Description

Technical Field

[0001] The present invention relates to the technical field of injection molding devices, and particularly relates to a rapid heat cycle injection molding device for automotive trim panels. Background Art

[0002] As an important decorative and functional component inside the vehicle, the quality and production efficiency of automotive trim panels have a crucial impact on the overall quality and cost of the vehicle; injection molding, as a commonly used method for processing plastic products, occupies an important position in the production of automotive trim panels.

[0003] During the operation of traditional automotive trim panel injection molding devices, a certain amount of plastic solution often remains at the injection port; the remaining plastic solution may enter the mold cavity together with the newly injected plastic solution during a new injection process; due to the possible differences in physical properties such as temperature and fluidity between this part of the remaining solution and the newly injected solution, it will cause the plastic solution to be unevenly distributed in the cavity; this uneven distribution will result in defects such as inconsistent local thickness and uneven surface on the automotive trim panel after molding, seriously affecting the appearance quality and dimensional accuracy of the trim panel and reducing the product qualification rate.

[0015] Beneficial effects 1. In the present invention, through the cooperative cooperation of the plugging block, the cross bar, the spring member and the piston block, the plastic solution inside the syringe can be completely extruded through the piston block, ensuring that there is no residue of the plastic solution in the syringe; when the piston block pushes out all the plastic solution in the syringe, the spring member pushes the cross bar to quickly reset, and the reset of the cross bar drives the plugging block to move synchronously, and the plugging block extrudes the residual plastic solution at the end of the syringe with accurate position and force; thus, after each injection is completed, the plastic solution inside and at the end of the syringe can be completely removed, effectively avoiding the residue of the plastic solution at the injection port; ensuring the appearance quality and dimensional accuracy of the decorative panel.

[0016] 2. In the present invention, during the injection stage, the heat-conducting oil furnace transports high-temperature heat-conducting oil to the cavity inside the moving mold through the liquid pump A via the heat-conducting oil pipe, so that the mold is quickly heated to an appropriate injection temperature, ensuring good fluidity of the material and ensuring the smooth progress of the injection molding process; when the injection is completed, the chiller transports cooling water to the inside of the moving mold through the liquid pump B via the cooling water pipe, quickly reducing the mold temperature and accelerating the cooling and shaping of the decorative panel.

[0017] 3. In the present invention, when the heat-conducting oil is injected into the cavity inside the moving mold, its hydraulic pressure will quickly act on one side of the drain plate, pushing the drain plate to move along the cavity and quickly squeezing out the residual cooling water in the cavity; similarly, when the cooling water is injected, the hydraulic pressure of the cooling water will push the drain plate to move in the reverse direction and squeeze out the heat-conducting oil from the cavity; at the same time, the inductive proximity sensor A and the inductive proximity sensor B monitor the position of the drain plate in real time and feed back the position information to the control module B; the control module B accurately controls the opening and closing of the solenoid valve A and the solenoid valve B according to these feedback signals; in this way, the heat-conducting oil and the cooling water can be quickly circulated and switched, greatly shortening the production cycle and significantly improving the production efficiency.

[0018] 4. In the present invention, by providing a reciprocating lead screw, a connecting block and a lifting seat, the sliding seat can drive the vibrating seat to move up and down outside the fixed mold through the auxiliary rod. At the same time, the vibration motor keeps running, and the vibration generated by it is efficiently conducted to the fixed mold through the vibrating seat, causing regular vibration of the fixed mold. The vibration of the fixed mold can make the bubbles in the solution float up and escape quickly, effectively preventing the existence of bubbles in the plastic solution and avoiding internal defects of the decorative panel caused by bubbles. And it enables the decorative panel in the fixed mold to be smoothly demolded under the action of vibration. This auxiliary demolding method avoids excessive adhesion between the decorative panel and the mold, reduces the damage to the decorative panel caused by the demolding force, ensures the integrity and smoothness of the surface of the decorative panel, and improves the appearance quality of the decorative panel.

[0037] Specific usage method and function of this embodiment: In the present invention, when in use, the air cylinder 202 is started, and the air cylinder 202 drives the moving die 204 to move horizontally through the guide rod 203, so that the moving die 204 is closed with the fixed die 101; then the heat-conducting oil furnace 301 and the liquid pump A 302 are started, and at the same time the solenoid valve A 306 is closed, and the solenoid valve B 3013 is in the open state; the liquid pump A 302 pumps the hot oil generated by the heat-conducting oil furnace 301 into the cavity inside the moving die 204 through the connecting hose A 303 and the heat pipe 304. The hot oil uses hydraulic pressure to push the liquid discharge plate 207, and the liquid discharge plate 207 quickly discharges the cooling water in the cavity; so that the heat-conducting oil heats the moving die 204, the fixed die 101 and the injection cavity; when the metal block 208 contacts the inductive proximity sensor A 209, the inductive proximity sensor A 209 transmits a signal to the control module B 205, and the control module B 205 opens the solenoid valve A 306 and closes the solenoid valve B 3013, so that the hot oil circulates in the cavity inside the moving die 204; the driving motor 406 is started, and the driving motor 406 drives the spiral feeding rod 405 to rotate, so that the plastic particles inside the storage barrel 402 are conveyed into the feeding cylinder 401. The plastic particles inside the feeding cylinder 401 are heated and melted by the electric heating ring 404, so that the plastic solution flows into the injection cylinder 102; when the hydraulic sensor 1010 detects that the hydraulic pressure inside the injection cylinder 102 reaches the predetermined value, the hydraulic sensor 1010 transmits a signal to the control module A 107, and the control module A 107 controls the driving motor 406 to stop working; at the same time, the control module A 107 controls the electric cylinder 105 to work, and the electric cylinder 105 drives the piston block 106 to move through the driving plate 104 and the injection rod 103. The piston block 106 pushes the plastic solution inside the injection cylinder 102; the plastic solution pushes the blocking block 109 open, so that the plastic solution is injected into the injection cavity. At the same time, when the plastic solution enters the injection cavity, the hydraulic sensor 1010 will always be subjected to hydraulic shock; when all the plastic solution inside the injection cylinder 102 is pushed out, the blocking block 109 quickly resets through the spring member and the cross bar 108, so that the residual solution at the end of the injection cylinder 102 is squeezed into the injection cavity; thus enabling the hydraulic sensor 1010 to return to the normal pressure value. At this time, the hydraulic sensor 1010 transmits a pressure signal to the control module A 107, and the control module A 107 controls the electric cylinder 105 to drive the driving plate 104 and the injection rod 103 to move in the reverse direction, so that the piston block 106 resets, and at the same time the driving motor 406 is started for the next injection process; when the injection of the plastic solution is completed, the liquid pump B 309 is started, and the liquid pump B 309 pumps the cooling water generated by the chiller 308 into the cavity inside the moving die 204 through the connecting hose B 3010 and the cooling pipe 3011, and at the same time the solenoid valve A 306 is opened and the solenoid valve B 3013 is closed; so that the cooling water uses hydraulic pressure to push the liquid discharge plate 207 in the reverse direction, and the liquid discharge plate 207 quickly discharges the hot oil in the cavity; so that the cooling water cools the moving die 204, the fixed die 101 and the plastic solution;When the metal block 208 comes into contact with the inductive proximity sensor B2010, the inductive proximity sensor B2010 transmits a signal to the control module B205. The control module B205 opens the solenoid valve B3013 and closes the solenoid valve A306, causing the cooling water to circulate within the internal cavity of the moving mold 204; thereby enabling the plastic solution to cool and form an automotive trim panel. Start the motor device to drive the reciprocating lead screw 502 to rotate. The reciprocating lead screw 502 drives the lifting seat 503 through the connecting block 504 to drive the sliding seat 505 to move up and down reciprocally.
