Description

A mold device for processing plastic products

Technical Field

The invention relates to the technical field of plastic processing molds, and in particular to a mold device used for processing plastic products.

Background Art

Plastic products are a general term for daily necessities and industrial products made of plastic as the main raw material, including products made of plastic by injection molding, vacuum forming and other processes. Plastic is a type of synthetic polymer material with plasticity. In the production process of plastic products, injection molding is generally used, that is, injection molding machines are used for production. The working principle of an injection molding machine is similar to that of a syringe for injections. It uses the thrust of a screw (or plunger) to inject the plasticized molten state (i.e., viscous flow state) plastic into a closed mold cavity, and obtains the product after solidification and finalization. Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and part removal. After the plastic part is taken out, the mold is closed again for the next cycle.

However, during demolding, since the plastic in the injection molding mechanism is still in a heated state, after demolding, it is very easy for the plastic to flow out through the concave mold plate due to temperature changes, thereby causing impurities to remain on the concave mold plate, causing impurities to be mixed into the product during the next injection molding, resulting in poor product quality or even direct scrapping; in addition, during the mold opening process, there are no protective measures for the convex mold plate and the concave mold plate, and the environment of the production workshop is complex, so external impurities are very easy to adhere to the mold, causing mold contamination, causing impurities to be mixed into the product, which also affects the quality of the product, and the product is often not completely cooled during the falling process, and there are no buffering measures during the falling process, which causes the parts to be hit hard, thereby causing deformation of the parts, resulting in a low yield rate of parts production, and causing great economic losses to the company.

Furthermore, in the present invention, through the setting of the synchronous cleaning mechanism, when the driving rod rotates and moves downward, the extrusion frame is pressed downward, so that the extrusion frame moves vertically in the extrusion groove, and at the same time the extrusion spring is stressed, and the extrusion frame drives the card block to be stuck in the card groove at the same time, and the movement of the extrusion frame drives the lifting shaft to move through the follower plate, and the lifting shaft moves in the follower groove, thereby driving the rotating column to rotate, and the rotation of the rotating column drives the swing rod to rotate, so that the swing rod drives the transverse rod to move through the swing shaft, and at the same time the swing shaft slides in the swing groove, and the transverse rod slides in the mounting plate, and then the transverse rod drives the two cleaning rods to move, so that the two cleaning rods clean the convex mold plate and the concave mold plate through two cleaning brushes, thereby further ensuring the cleanliness of the mold, thereby ensuring the production quality of the mold.

Furthermore, in the present invention, through the setting of the cooling buffer mechanism, when the mold is opened, the driving rod rotates and the squeeze switch is pressed so that the air pump can be turned on. At this time, the gas output by the air pump is blown out through the multiple blowing holes on the buffer plate, which can blow and cool the plastic parts that are about to fall. At the same time, when the plastic product falls on the buffer plate, it drives the multiple buffer rods to move downward, and the buffer rods move in the buffer groove and drive the buffer spring to be stressed. Then, under the rebound force of the buffer spring, the impact on the buffer plate is offset, so that the plastic product can be further cooled when it falls, and at the same time, it can be buffered, thereby ensuring the production quality of the plastic product.

In summary, the working principle of a mold device for plastic product processing provided by an embodiment of the present invention is:

When the movable mold base 3 is reset, the pushing plate 717 is pushed to slide. The pushing plate 717 can drive the driving plate 714 to rotate when sliding, and the driving plate 714 is connected to the driving rod 713 as a whole through the driving shaft 716, and when the driving plate 714 rotates, the driving rod 713 is driven to rotate through the driving shaft 716, and rotates around the driving shaft 716, so that the driving plate 714 only needs to rotate a small angle to drive the driving rod 713 to rotate a larger angle through the driving shaft 716. At this time, the driving rod 713 drives the driving frame 704 to move through another driving shaft 716, and the driving shaft 716 slides in the driving groove 715. When the driving frame 704 moves, it moves vertically in the two stretching grooves 706 through the two stretching rods 705, and the two stretching springs 707 are stressed. The driving frame 704 drives the blocking frame 702 to move through the sliding block 708, so that the blocking frame 702 is driven to move vertically when the driving rod 713 rotates. When the blocking frame 702 moves, the two guide shafts 711 slide in the two guide grooves 710, thereby making the blocking frame 702 move horizontally. At the same time, the blocking frame 702 slides horizontally on the driving frame 704 through the sliding block 708, so that the blocking frame 702 moves downward and the purpose of synchronous lateral movement is achieved, so that the blocking frame 702 drives the blocking head 703 to block the pouring port, avoiding the problem of plastic overflow during discharge, ensuring the cleanliness of the mold, and thus ensuring the production quality of the mold. Similarly, when the movable mold base 3 moves to close the mold, at this time, under the resilience of the two stretching springs 707, the two stretching rods 705 drive the driving frame 704 to reset, and the driving frame 704 drives the driving rod 713 to rotate upward through the driving shaft, so that the driving rod 713 drives the driving plate 714 to rotate through another driving shaft 716, so that the driving plate is moved to reset the push plate 717, and then the blocking frame 702 can be reset without affecting the production of the mold.

Furthermore, when the driving rod 713 rotates and moves downward, the extrusion frame 812 is pressed downward, so that the extrusion frame 812 moves vertically in the extrusion groove 813, and the extrusion spring 814 is stressed, and the extrusion frame 812 drives the clamping block 816 to be clamped in the clamping groove 815 at the same time. The movement of the extrusion frame 812 drives the lifting shaft 810 to move through the follower plate 809, and the lifting shaft 810 moves in the follower groove 811, thereby driving the rotating column 808 to rotate. The rotation of the rotating column 808 drives the swing rod 805 to rotate, so that the swing rod 805 drives the lateral movement rod 802 to move through the swing shaft 806, and the swing shaft 806 slides in the swing groove 807, and the lateral movement rod 802 is on the mounting plate 801. The two cleaning rods 803 are moved inwardly, and the two cleaning rods 803 are driven by the transverse rod 802 to move, so that the two cleaning rods 803 clean the male mold plate 4 and the female mold plate 5 through the two cleaning brushes 804, further ensuring the cleanliness of the mold, thereby further ensuring the production quality of the mold; in addition, when the movable mold base 3 is reset, the push plate 717 is driven to move, so that the push plate 717 drives the extrusion frame 812 to move upward, and then the extrusion frame 812 drives the card block 815 to disengage from the card slot 816. At this time, with the help of the rebound force of the extrusion spring 814, the extrusion frame 812 is helped to reset, and then the transverse rod 802 can be reset, so that the transverse rod 802 can be reset before the mold is closed, without affecting the mold closing;

Furthermore, when the mold is opened, the driving rod 713 rotates and squeezes the switch 909 so that the air pump 907 can be turned on. At this time, the gas output by the air pump is blown out through the multiple blowing holes 906 on the buffer plate 902, so as to blow and cool the plastic parts that are about to fall. At the same time, when the plastic product falls on the buffer plate 902, it drives the multiple buffer rods 904 to move downward, and the buffer rods 904 move in the buffer groove 903, and drive the buffer spring 905 to be stressed, and then under the rebound force of the buffer spring 905, the impact on the buffer plate 902 is offset, so that the plastic product can be further cooled when it falls, and at the same time, it can be buffered, thereby ensuring the production quality of the plastic product.
