Detailed ways

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific implementation modes.

Example

As shown in Figures 1-4 and 6, this embodiment discloses a rapid prototyping glass lampshade manufacturing mold, which includes a shell 1. The lower end of the shell 1 is provided with a bracket 2. The bracket 2 is used to elevate the shell 1. This facilitates the installation of the motor 3 at the lower end of the housing 1. The upper end of the housing 1 is provided with a rotating rod 2 5. The outer surface of the rotating rod 2 5 is provided with two cover plates 6 for closing the housing 1. The two closed together The two cover plates 6 are convenient for shaping the upper part of the glass lampshade. The upper middle portions of the two cover plates 6 are respectively provided with two semi-fixed rings 17 and two semi-fixed rings 28 for fixing the two cover plates 6. , when the semi-fixed ring one 7 and the semi-fixed ring two 8 located at the same level are connected together, the two cover plates 6 are fixed together to prevent the two cover plates 6 from suddenly separating when the glass is rotating, causing the glass to fail to shape. , the ends of the two semi-fixed rings one 7 and the two semi-fixed rings two 8 that are close to each other are provided with two connecting rods 61, so that one of the semi-fixed rings one 7 and the two semi-fixed rings 8 are located above the shell 1, facing The blow tube is connected to the glass and used to blow mold the glass into a hollow shape to prevent the blow tube from deflecting when the glass rotates, causing damage to the glass, thus reducing the probability of producing defective glass lampshades.

Specifically, please refer to Figure 2-3. The inside of the semi-fixed ring 7 is provided with two symmetrically arranged empty grooves 71 on one side close to its inner surface. The inner surfaces of the semi-fixed ring 7 and the semi-fixed ring 2 8 are evenly spaced. A semi-rotating ring 9 is provided, and the two semi-rotating rings 9 are brought together to fix the blow pipe, so that the semi-rotating ring 9 can rotate on the inner surfaces of the semi-fixed ring 1 7 and the semi-fixed ring 2 8 as the blow pipe rotates. In order to connect and fix the semi-fixed ring 1 7 and the semi-fixed ring 2 8 that are rotated together, in this embodiment, the upper end of the semi-rotating ring 9 located inside the semi-fixed ring 7 is provided with two symmetrically arranged fixing mechanisms 93 . The mechanism 93 has two functions. One is to fix the semi-fixed ring 1 7 and the semi-fixed ring 2 8 , and the other is to facilitate the control of the semi-rotating ring 9 to rotate. After the motor 3 stops working, the fixing mechanism 93 is used to control the semi-rotation. The ring 9 continues to rotate to its initial position, and the T-shaped magnet 72 is sucked back into its original position. The fixing mechanism 93 includes a mounting box 931 fixedly connected to the upper end of the semi-rotating ring 9. The mounting box 931 is close to the center of the semi-fixed ring 7 One end of the shaft is provided with a T-shaped magnet 932. One end of the T-shaped magnet 932 away from the central axis of the semi-fixed ring 17 penetrates the installation box 931 and extends to the inside of the empty slot 71. The upper and lower outer end walls of the T-shaped magnet 932 are evenly spaced. There is a limit plate 933 located in the inner cavity of the installation box 931. One end of the limit plate 933 close to the central axis of the semi-fixed ring 7 is provided with a spring 934 together with the inner wall of the installation box 931;

It can be seen that by pressing the T-shaped magnet two 932 outward, it moves into the empty slot 71, pushing the T-shaped magnet one 72 to move outward, and then returns to its original position under the pull of the spring 934 and the limiting plate 933. , to avoid affecting the rotation of the semi-rotating ring 9;

Specifically, the outer surface of the semi-fixed ring 8 is provided with two symmetrically arranged L-shaped external connecting plates 83. The vertical parts of the two L-shaped external connecting plates 83 are provided with fixing grooves 85 penetrating their left and right outer end walls. The interior of the empty slot 71 is provided with a T-shaped magnet 72 that is magnetically attracted to the T-shaped magnet 2 932. When the semi-fixed ring 7 and the semi-fixed ring 2 8 are separated, the T-shaped magnet 72 can follow the T-shaped magnet 72. The two magnets 932 move together and disengage from the fixed groove 85, so that the semi-fixed ring 7 and the semi-fixed ring 2 8 are no longer connected. The horizontal part of the T-shaped magnet 72 penetrates the outer surface of the semi-fixed ring 7 and is slidably connected to the fixed groove. 85 interior;

It can be seen from this that the T-shaped magnet 1 72 is pushed through the fixed groove 85 by the push of the T-shaped magnet 2 932 , so that the L-shaped external plate 83 and the semi-fixed ring 2 8 cannot rotate away, thereby moving the semi-fixed ring 1 7 and 8 . The semi-fixed rings 2 and 8 are fixed together and facilitate subsequent disassembly;

Specifically, an L-shaped clamping plate 84 is provided at one end of the L-shaped external connection plate 83 away from the semi-fixed ring 28. The lower part of the horizontal part of the L-shaped clamping plate 84 is a triangular structure. The L-shaped clamping plate 84 is slidably connected to the L-shaped external connection plate 83. on the T-shaped magnet 72 so that it can be pushed up by the T-shaped magnet 72 as it moves. The end of the T-shaped magnet 72 away from the empty slot 71 is an inclined surface structure that fits the horizontal part of the L-shaped clamping plate 84 to avoid Push the L-shaped clamping plate 84 upward, and the upper end of the T-shaped magnet 72 close to the inclined surface is provided with a clamping groove 73 for connecting with the triangular structure of the L-shaped clamping plate 84. The L-shaped clamping plate 84 is moved by the T-shaped magnet. After being lifted up, the one 72 moves down by its own gravity, so that the triangular structure of the horizontal part of the L-shaped clamping plate 84 is slid into the clamping groove 73, and is stuck, so that the T-shaped magnet one 72 can no longer follow the T-shaped magnet. Two 932 moved back together;

As can be seen from the above, the T-shaped magnet 2 932 is pressed outward, and the spring 934 is compressed, so that a part of the T-shaped magnet 932 away from the central axis of the semi-fixed ring 7 moves into the empty slot 71 , and the T-shaped magnet 72 is squeezed to move outward and slide. Insert it into the fixing slot 85. Then, as the T-shaped magnet 72 continues to move, use its inclined surface to push up the L-shaped clamping plate 84 until the inclined part of the T-shaped magnet 72 completely moves to the outside of the fixing slot 85. Then the L-shaped clamping plate 84 moves down by its own gravity, so that the triangular structure on the horizontal part is slid into the clamping groove 73, thereby fixing the T-shaped magnet one 72, and then directly releasing the T-shaped magnet two 932. Let it return to its original position under the action of spring 934;

When the semi-fixed ring one 7 and the semi-fixed ring two 8 are separated, pull up the L-shaped clamping plate 84 to separate the L-shaped clamping plate 84 from the T-shaped magnet one 72, and then press the T-shaped magnet two 932 to use the T-shaped clamping plate 84. The mutual attraction between magnet two 932 and T-shaped magnet one 72 causes T-shaped magnet one 72 to move back until T-shaped magnet one 72 is detached from the fixing groove 85, thereby separating semi-fixed ring one 7 and semi-fixed ring two 8 Separate, and then it is convenient to open the cover 6 and take out the formed glass lampshade.

Further, please refer to Figure 4. A chute 81 is provided in the middle of the inner surface of the semi-fixed ring one 7 and the semi-fixed ring two 8. The upper and lower inner walls of the chute 81 are provided with a chute 81 that penetrates the semi-fixed ring one 7 and the semi-fixed ring 2. The open grooves 82 at one end of the two 8's are close to each other. The middle part of the outer surface of the semi-rotating ring 9 is provided with a semi-connecting ring 92 that is slidably connected to the inside of the chute 81. The middle parts of the upper and lower outer end walls of the semi-connecting ring 92 are provided with arcuate grooves. 921. There are multiple balls 922 inside the arcuate groove 921 and the open groove 82. The rotation of the balls 922 in the arcuate groove 921 and the open groove 82 is used to reduce the friction of the semi-connection ring 92 rotating in the chute 81. This facilitates the semi-rotating ring 9 to rotate together with the blow pipe;

Furthermore, the inner surface of the semi-rotating ring 9 is provided with a semi-rubber ring 91. The inner surface of the semi-rubber ring 91 is relatively rough. The friction force of the semi-rubber ring 91 on the blow pipe is used to enable the semi-rotating ring 9 to follow the blow pipe. Rotate to maintain the stability of the blow tube when rotating and prevent it from shaking during rotation, resulting in damage to the glass lampshade;

Specifically, there is a mold body 4 inside the shell 1, and a motor 3 is provided at the lower end of the shell 1. The output end of the motor 3 is provided with a bottom wall of the inner cavity of the shell 1 through a coupling and is fixedly connected to the lower end of the mold body 4. The rotating shaft 31 uses the motor 3 to rotate the rotating shaft 31 and the mold body 4, and controls the rotation of the uncooled glass lampshade in the mold body 4, so that the material inside is evenly distributed, thereby reducing the generation of defective products.

Therefore, the specific implementation of the embodiment is:

First put the unformed glass into the mold body 4, and then use the handle on the cover plate 6 to merge the two cover plates 6 together, so that the semi-fixed ring 1 7 and the semi-fixed ring 2 8 pair the blow pipe on the glass Clamp and fix, and then push the T-shaped magnet 2 932 outward, so that a part of the central axis of the T-shaped magnet 2 932 away from the semi-fixed ring 1 7 moves into the empty slot 71 , squeeze the T-shaped magnet 1 72 , move outward, slide, insert and fix. In the groove 85, as the T-shaped magnet 72 continues to move, its inclined surface is used to push up the L-shaped clamping plate 84 until the inclined part of the T-shaped magnet 72 completely moves to the outside of the fixing groove 85, and then L The T-shaped clamping plate 84 then moves down by its own gravity, so that the triangular structure on the horizontal part is slidably inserted into the clamping groove 73, thereby fixing the T-shaped magnet one 72, and then directly loosens the T-shaped magnet two 932 to make it Return to the original position under the action of the spring 934, and then start the motor 3 to control the rotation of the rotating shaft 31 and the mold body 4, so that the blow pipe uses the half rubber ring 91 to drive the two half rotating rings 9 to rotate;

After the glass lampshade is formed, pull up the L-shaped clamping plate 84 to separate the L-shaped clamping plate 84 from the T-shaped magnet one 72, and then press the T-shaped magnet two 932 again, using the T-shaped magnet two 932 and the T-shaped magnet one The mutual attraction between the T-shaped magnets 72 causes the T-shaped magnet 72 to move back until the T-shaped magnet 72 is detached from the fixing groove 85, thereby separating the semi-fixed ring 7 and the semi-fixed ring 28, thereby facilitating the cover plate 6 Open and take out the formed glass lampshade.

Example

This embodiment adds a water cooling circulation structure on the basis of Embodiment 1, so that the taken-out glass lampshade can be directly cooled and formed, reducing subsequent steps. As shown in Figure 5-10, a cooling cavity 45 is provided inside the mold body 4. The bottom wall of the cooling cavity 45 is a tapered surface with a high middle and low surroundings, which facilitates the coolant entering the cooling cavity 45 to quickly flow to the surroundings to avoid accumulation in the middle and affect the subsequent entry of the coolant. The upper surface of the outer surface of the mold body 4 is evenly opened There are a plurality of water inlet holes 41 and 42. The water outlet of the water inlet hole 42 and the bottom side of the inner surface of the water inlet are at the same level, so that the part of the coolant covered by the L-shaped plate 15 can finally be free. The cooling cavity 45 flows into the cooling cavity 45 to reduce the accumulation of remaining coolant. The lower part of the inner surface of the cooling cavity 45 is provided with two outlets 43 penetrating its outer surface. The cooling liquid is sprayed through the water inlet hole 41 and the water inlet hole 2 42 Entering the cooling cavity 45, the inner wall of the cooling cavity 45 is cooled, thereby cooling the formed glass lampshade to avoid the glass lampshade cooling too fast, causing it to break;

Specifically, please refer to Figure 6-8. The inner lower side of the shell 1 is provided with a mounting slot 11 and two mounting slots 12. The left and right sides of the shell 1 are both provided with a mounting slot 3 13 and are connected to the outlet channel 43. Through the L-shaped groove 14, the cooling liquid sprayed into the cooling cavity 45 is thrown to the outside by the rotational force of the mold body 4, and finally enters the L-shaped groove 14 at the moment when the outlet water tank 43 is connected to the L-shaped groove 14. Thereby replenishing the coolant in the L-shaped groove 14, the installation groove three 13 is located directly above the installation groove two 12 and connected with the installation groove two 12. The L-shaped groove 14 is provided with three holes on the upper side of the side wall close to the mold body 4. The communication groove 18 connecting the water inlet hole one 41 and the water inlet hole two 42 facilitates the coolant in the L-shaped groove 14 to enter the cooling cavity 45 at the moment when it communicates with the water inlet hole one 41 and the water inlet hole two 42 through the communication groove 18 Inside, the glass lampshade is cooled;

Specifically, the outer surface of the rotating shaft 31 is provided with a bevel gear 32 located inside the installation groove 11. The left and right inner walls of the installation groove 11 are provided with a bevel gear 2 33 meshing with the bevel gear 1 32. The bevel gear 2 33 The end of the transmission shaft 34 away from the rotating shaft 31 is provided with a transmission shaft 34. The end of the transmission shaft 34 away from the bevel gear 2 33 extends to the inside of the mounting groove 2 12 and is provided with a disc 35. The end of the disc 35 away from the transmission shaft 34 is provided with a rotating shaft 34 on the outside. Rod one 351, the outer surface of the rotating rod 351 is provided with a moving rod 36, the upper part of the moving rod 36 extends to the inside of the installation groove three 13 and is provided with a moving rod two 37, the upper end of the moving rod two 37 passes through the installation groove three The top wall of 13 is also provided with a flushing mechanism 38;

It can be seen that while the motor 3 uses the rotating shaft 31 to control the rotation of the mold body 4, it also uses the meshing of the first bevel gear 32 and the second bevel gear 33 to rotate the transmission shaft 34 and the disk 35, so that the rotating rod is connected to the The moving rod 36 on the outer surface of the first 351 moves up and down, thereby driving the moving rod 37 and the flushing mechanism 38 to move up and down, pushing up the coolant in the L-shaped groove 14 and increasing the pressure in the upper part of the L-shaped groove 14 , so that the cooling liquid in the cooling chamber can be sprayed into the cooling cavity 45 through the communication groove 18, the first water inlet 41 and the second water inlet 42, thereby indirectly cooling the glass lampshade.

Specifically, the flushing mechanism 38 includes a connecting plate 381. The connecting plate 381 is slidingly connected between the L-shaped groove 14 and the L-shaped plate 15, so that the coolant in the L-shaped groove 14 can flow up into the L-shaped plate 15. and the communication groove 18, thereby increasing the pressure of the coolant so that it can be sprayed out quickly. The upper end of the connecting plate 381 is provided with a flow groove 384 that runs through its lower end. Four sliding rods 382 are provided inside the connecting plate 381. And the four sliding rods 382 are evenly distributed outside the flow groove 384. The upper ends of the four sliding rods 382 penetrate the upper end of the connecting plate 381 and are jointly provided with a sealing plate 383;

It can be seen that the moving rod 37 first pulls the flushing mechanism 38 downward, causing the coolant in the lower part of the L-shaped groove 14 to impact the sealing plate 383, forcing the sealing plate 383 to move upward to open the flow groove 384, so that the L-shaped groove 14 The coolant in the lower part can enter the upper part of the L-shaped groove 14, and then the flushing mechanism 38 moves upward with the moving rod 237, and the pressure of the coolant is used to make the sealing plate 383 move downward again to close the flow groove 384, so that the flushing mechanism 38 moves upward. The water mechanism 38 pushes part of the cooling liquid to move upward, increasing the pressure at the upper part of the L-shaped groove 14 so that the cooling liquid can be sprayed out to cool the glass lampshade.

Further, the inner surface of the cooling cavity 45 is provided with a flow guide plate 44 that is not in contact with its bottom wall. The upper inner side of the flow guide plate 44 has a conical structure with the same shape and different sizes as the lower part of the inner cavity of the mold body 4, so that the flow guide plate 44 can enter the cooling cavity. The coolant in the lower part of 45 can re-flush the inner surface of the cooling cavity 45 under the action of the upper inclined surface of the guide plate 44, thereby facilitating the overall cooling of the glass lampshade and avoiding uneven cooling and heating on the surface causing rupture;

Further, please refer to Figure 8-9. The plurality of water inlet holes 41 and 42 are all tapered structures with a larger inner diameter on the side close to the housing 1. By narrowing the water inlet holes 1 and 41, 2. The diameter of the water outlet is 42 to increase the speed at which the coolant comes out, so that the coolant can spray and cool the inner surface of the cooling cavity 45 to avoid the surface of the glass lampshade from cracking due to excessive cooling speed;

Further, an L-shaped plate 15 is provided in the upper middle part of the side wall of the L-shaped groove 14 close to the mold body 4. The upper end of the vertical part of the L-shaped plate 15 located in the same plane is located at the uppermost water inlet hole 41. Above, it is convenient for the coolant to completely cool the glass lampshade. The upper end of the horizontal part of the L-shaped plate 15 is tangent to the lower side of the inner surface of the water inlet hole 2 42, so that the coolant in the part covered by the L-shaped plate 15 can finally be free. flows into the cooling cavity 45 to reduce the accumulation of remaining coolant. The lower end of the L-shaped plate 15 is at the same level as the bottom wall of the horizontal part of the L-shaped groove 14 to prevent the coolant from using the L-shaped plate 15 and the L-shaped groove. The gap between 14 drops back, affecting the subsequent injection of coolant;

Further, the upper part of the side wall of the L-shaped groove 14 away from the mold body 4 is provided with an L-shaped plate 2 16 that is not in contact with the L-shaped plate 1 15 . The vertical part of the L-shaped plate 16 is located vertically on the L-shaped plate 1 15 . Above between the straight part and the communication groove 18, the L-shaped plate 16 is used to allow the rising coolant to enter between the L-shaped plate 15 and the communication groove 18 to prevent the coolant from leaving directly through the transfer pipe 17. This causes a waste of resources. The side of the outer surface of the housing 1 close to the rotating rod 2 5 is provided with a transfer pipe 17 that communicates with the cavity between the upper end of the L-shaped plate 2 16 and the top wall of the L-shaped groove 14. The transfer pipe 17 is used to discharge cooling. The steam in the cavity 45 prevents the device from being damaged due to excessive pressure in the mold body 4 .

Therefore, the specific implementation of the embodiment is:

While the motor 3 controls the rotation of the mold body 4 through the rotating shaft 31, it also controls the rotation of the transmission shaft 34 and the disk 35 through the meshing of the bevel gear 1 32 and the bevel gear 2 33, so that the outer surface of the rotating rod 351 is connected The moving rod one 36 moves downward, so that the moving rod two 37 pulls the flushing mechanism 38 to move downward. During the downward movement of the flushing mechanism 38, the coolant in the lower part of the L-shaped groove 14 will impact the sealing plate 383. The sealing plate 383 is forced to move upward to open the flow groove 384, so that the coolant in the lower part of the L-shaped groove 14 can enter the upper part of the L-shaped groove 14, and then the flushing mechanism 38 moves upward with the moving rod 237, using the pressure of the coolant The sealing plate 383 is moved downward again to close the flow groove 384, so that the flushing mechanism 38 pushes part of the coolant to move upward, and then through the steering of the L-shaped plate 2 16, the coolant enters the L-shaped plate 15 and is connected Between the grooves 18, the communication groove 18, the first water inlet 41 and the second water inlet 42 are finally used to spray the coolant into the cooling cavity 45 to indirectly cool the glass lampshade to avoid the glass lampshade from breaking.
