through setting up reinforcing frame 14 to make the drawing together of penetrating of gluing mechanism 1 glue subassembly 12, penetrate gluey subassembly 13 and material pipe subassembly 11 and set up on reinforcing frame 14, make when glue subassembly 12, penetrate gluey subassembly 13 or material pipe subassembly 11 have the trend of twisting under the effect that the lead screw motion is nonparallel, reinforcing frame 14 relies on self structural strength to overcome the trend of twisting, avoided twisting the material pipe subassembly 11 centering problem that leads to, improved and penetrated gluey accuracy nature.

Through setting up spacing slide rail 141 parallel with material pipe subassembly 1111 to make the two boards 123 that penetrate of sol subassembly 12 cooperate spacing slide rail 141 to set up the gliding tie wing 122 on spacing slide rail 141, make the slide rail pass through tie wing 122 can further prevent to penetrate the probability that glue subassembly 13 twists appear, can provide the support for sol subassembly 12 simultaneously, further guaranteed the steadiness of penetrating glue subassembly 13, improved and penetrated gluey accuracy.
Although the cooperation of the limiting slide rail 141 and the connecting wing 122 provides a supporting effect for the sol assembly 12, when the contact surface of the limiting slide rail 141 and the connecting wing 122, that is, the supporting point of the limiting slide rail 141 to the sol assembly 12 is far away from the center of gravity of the sol assembly 12, the force arm of the center of gravity to the supporting point is longer whenever the center of gravity of the sol assembly 12 has a trend of moving parallel to the ground, the burden on the slide rail is larger, the slide rail is damaged, or the support is unstable, the stability of the glue injection assembly 13 is reduced, the glue injection accuracy is reduced, in order to avoid the occurrence of the situation, the distance between the two slide rails and the ground is consistent, the height difference between the connecting surface of the glue injection two plates 123 and the limiting slide rail 141 and the axis of the material pipe assembly 11 is 5-10 mm, through calculating that the gravity center of the sol component 12 is located at the position 9-11 mm above the axial center of the material pipe component 11, in order to enable the supporting point to be slightly lower than the sol component 12, the supporting stability is ensured, the shape of the connecting wing 122 ensures that the connecting wing 122 is arranged on the limiting slide rail 141, the connecting surface of the connecting wing 122 and the limiting slide rail 141 is 5-10 mm higher than the axial center height of the screw 111, at the moment, the supporting point of the sol component 12 supported on the limiting slide rail 141 can be ensured to be slightly higher than the gravity center of the sol component 12, when the sol component 12 shakes or twists, and when the gravity center of the sol component 12 has a trend of moving parallel to the ground, the gravity center has a shorter tendency to the supporting point, the burden to the slide rail is smaller, the shaking probability is smaller, the supporting is more stable, and the stability and the glue injecting accuracy of the glue injecting component 13 are improved.
By setting the connecting surface of the connecting wing 122 and the limiting slide rail 141 to be 5-10 mm higher than the axial center of the screw 111, the force arm of the gravity center to the connecting point when the sol assembly 12 shakes is reduced, and the support stability and the glue injection accuracy are improved.
In the above process, when the sol assembly 12 twists, besides the limit sliding rail 141, the connecting wing 122 has a certain deformation trend, when the connecting wing 122 deforms, the positions of the sol assembly 12 to the two sliding rails change, so that the supporting stability is reduced, in order to ensure the structural strength of the connecting wing 122, the deformation probability is reduced, the ratio of the span of the connecting wing 122 to the thickness is 0.3-0.4, specifically, the span of the connecting wing 122 is the distance between the two limit sliding rails 141, the thickness is the dimension vertical to the ground direction after being arranged on the connecting wing 122, when the thickness of the connecting wing 122 is 0.3-0.4 times of the span, the dimension vertical to the ground direction is thicker, and when the connecting wing 122 has the deformation trend, the supporting stability and the glue injecting accuracy can be better resisted.
Besides the shaking of the material pipe assembly 11 caused by the twisting of the glue injection assembly 13, the whole pitching of the glue injection mechanism 1 can also lead the material pipe assembly 11 to deviate from the cavity, so that the glue injection accuracy is reduced, in the process of injecting glue by the structure, due to the fact that the material pipe assembly 11 is required to resist the trend of pushing the material pipe assembly 11 away from the cavity by high-pressure raw materials in the cavity, the glue injection assembly 13 is required to continuously give larger pressure to the sol assembly 12 and the material pipe assembly 11, so that the motor of the glue injection assembly 13 needs to output larger power and has larger volume, and when the motor of the glue injection assembly 13 is arranged at one end of the glue injection mechanism 1 away from the die clamping mechanism 2, the gravity center of the whole glue injection mechanism 1 is caused to deviate from one end of the die clamping mechanism 2, the supporting point of the glue injection mechanism 1 is deviated, the whole pitching of the glue injection mechanism 1 is possibly caused, and in order to reduce the occurrence of the situation, the reinforcing frame 14 is a front wall close to the metal plate structure at one end of the injection molding machine, the metal plate structure at one end of the reinforcing frame 14 far away from the injection molding machine is a rear wall, the dimension of the front wall along the direction perpendicular to the ground is consistent with the dimension of the rear wall along the direction perpendicular to the ground, the dimension of the front wall along the axial direction of the opening is 3-4 times that of the rear wall, specifically, the materials of the front wall and the rear wall are consistent, the dimensions of the front wall and the rear wall are consistent in the direction perpendicular to the ground and in the direction parallel to the ground and perpendicular to the axial direction of the opening, at the moment, the dimensions of the front wall and the rear wall are only distinguished in the axial direction of the opening, the mass of the front wall is 3-4 times that of the rear wall, at the moment, the heavy front wall enables the center of gravity of the whole glue injection mechanism 1 to be closer to the front wall, the integral pitching caused by the fact that the center of gravity of the glue injection mechanism 1 is excessively far away from one end of the glue injection mechanism 1 is avoided, the probability of the decrease of the glue injection accuracy is reduced.
In order to further reduce the weight of the rear wall, the weight contrast of the front wall and the rear wall is increased, so that the gravity center of the glue injection mechanism 1 is further close to the front wall, the strength of the rear wall is ensured, a plurality of lightening holes are dug in the rear wall, after the lightening holes are formed, the weight of the rear wall is further reduced, and meanwhile, when the rear wall has a deformation trend, the probability of deformation of the rear wall is reduced due to the structures around the lightening holes, and the strength of the rear wall and the reinforcing frame 14 is ensured.
Sometimes, the glue injection mechanism 1 needs to integrally move, so that the glue injection mechanism 1 is convenient to integrally move, the base slide rail 15 is arranged below the reinforcing frame 14, the glue injection mechanism 1 is slidably arranged on the base slide rail 15, and when the glue injection mechanism 1 needs to integrally move, the glue injection mechanism slides along the base slide rail 15.
When the glue injection assembly 13 pushes the sol assembly 12 to move, the connecting wing 122 can slide along the limiting slide rail 141, at the moment, the connecting wing 122 can slide out along the limiting slide rail 141 with probability, in order to avoid the occurrence of the situation, one end of the limiting slide rail 141, which is close to the injection molding machine, is provided with a limiting plate, when the connecting wing 122 slides to one end along the limiting slide rail 141, the connecting wing 122 is abutted with the limiting plate, the limiting plate prevents the further sliding of the connecting wing 122, and the blocking of the connecting wing 122 is completed.
The limiting slide rail 141 is in the in-process that supports linking wing 122 and sol subassembly 12 to and linking wing 122 is taking place to twist with the in-process of limiting slide rail 141's butt, and limiting slide rail 141 possesses the trend of deformation under external force, in order to reduce the probability that limiting slide rail 141 warp under external force, limiting slide rail 141 comprises chromium molybdenum alloy, and chromium molybdenum alloy's hardness is higher, when receiving external force, is difficult to take place deformation yet.
After the injection molding of the cavity is completed by the injection molding mechanism 1, the mold clamping mechanism 2 is required to be kept away, the mold opening of the mold clamping mechanism 2 is facilitated, an injection moving oil cylinder is arranged between the reinforcing frame 14 and the injection molding machine for completing the action of keeping away from the mold clamping mechanism 2, and when the injection molding mechanism 1 is required to be pushed to keep away from the mold clamping mechanism 2, the injection moving oil cylinder stretches to drive the injection molding mechanism 1 to slide along the base sliding rail 15.
The working principle and the using flow of the invention are as follows:
during injection molding, the movable template and the fixed template of the mold closing mechanism 2 are closed to form a cavity, raw materials enter the cavity of the material pipe assembly 11 from the charging hole 112, the sol motor 121 drives the screw 111 to rotate, the screw 111 enables the raw materials to be dissolved and approach to an opening, meanwhile, the material pipe assembly 11 is pushed by the glue injection assembly 13 to slide in the opening and approach to and extend into the opening of the cavity, the raw materials enter the cavity from the material pipe, and in the injection molding process, the material pipe assembly 11 is continuously pushed by the glue injection motor, so that the material pipe assembly 11 overcomes the trend of raw materials in the cavity to gush out, and is maintained in situ until injection molding is completed;
when the glue injection mechanism 1 has a twisting tendency, the connection part of the glue injection assembly 13 and the reinforcing frame 14 presses the reinforcing frame 14, and the reinforcing frame 14 keeps all parts of the glue injection assembly 13 in place by virtue of the strength of the reinforcing frame 14; meanwhile, the reinforcing frame 14 has a certain weight, so that when the glue injection mechanism 1 has a tendency of shaking integrally and the material pipe assembly 11 has a tendency of deviating from a cavity, the reinforcing frame 14 reduces shaking of the glue injection mechanism 1 by means of self weight;
when the glue injection assembly 13 pushes the glue assembly 12 and the material pipe assembly 11 to slide along the opening, the connecting wings 122 are synchronously driven to slide along the sliding rails, when the glue injection assembly 13 has a twisting trend, besides the jacking reinforcing frame 14, the connecting wings 122 are driven to extrude the sliding rails, at the moment, the sliding rails jack the grooves of the connecting wings 122, so that the glue injection assembly 13 is further prevented from twisting, meanwhile, the sliding rails arranged below the connecting wings 122 can provide additional support for the connecting wings 122, namely the glue injection two plates 123 and the glue injection assembly 12, and the stability of the glue injection assembly 13 in the glue injection process is further ensured.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
