Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts production equipment, and specifically to an injection mold base for automotive headlight production and its preparation process. Background Art

[0002] In the production process of automotive headlights, the injection mold base is a crucial piece of equipment. Many problems that need to be solved urgently have emerged in the production process of traditional injection mold bases. In the product removal link, traditional injection mold bases lack the automatic and precise product removal mechanism achieved by the upper component transmission structure in the present invention. Usually, manual operation is required to remove the headlight products after injection molding, and this method is extremely inefficient. According to relevant statistics, the speed of manually removing headlight products is much lower than that of automated equipment, and the hourly output is only one-third or even lower than that of automated equipment. Moreover, manual operation is greatly affected by human factors. Workers are prone to fatigue during long-term repetitive operations, resulting in collisions, scratches, etc. during the part removal process, and the product damage rate is as high as 10% - 15%, seriously affecting the stability of product quality, and further increasing production costs and the defective rate of products. In terms of cooling, the cooling system of traditional injection mold bases cannot achieve the mobile cooling cycle using the adsorption device as in the present invention. Its cooling effect is not good, often resulting in too high a mold temperature and uneven temperature drop. This will cause quality problems such as shrinkage deformation and surface defects in the headlight during the molding process, reducing the yield rate of products. At the same time, traditional cooling systems often operate at a continuous high power without effectively recycling water resources, resulting in high energy consumption. From the perspective of process coordination, each process of traditional injection mold bases is independent of each other and lacks a close coordination mechanism. Processes such as injection molding, ejection, adsorption, and cooling cannot achieve seamless cooperation through the mold base structure design as in the present invention. For example, after injection molding, the ejection and adsorption processes need to be operated manually or by an additional control system respectively, resulting in unsmooth connection between processes and an extended production cycle. Moreover, the operating parameters of the equipment for each process are difficult to automatically adjust according to the actual production situation, unable to adapt to complex and changeable production requirements, and the overall automation degree and stability of the production process are poor, seriously restricting the improvement of the production efficiency and quality of automotive headlights. Therefore, it is of great practical significance to develop an injection mold base for automotive headlight production that can improve production efficiency, ensure product quality, reduce energy consumption, and have good process coordination. Summary of the Invention

[0003] The object of the present invention is to provide an injection mold base for automobile headlamp production and its working method, so as to solve the problems existing in the prior art, such as difficult extraction of headlamps, poor cooling effect, high energy consumption, and poor process coordination, and realize the efficient, high-quality and energy-saving automated production of automobile headlamps.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: The technical solution provided by the present invention is: an injection mold base for automobile headlamp production, including a bracket, a support plate is fixedly arranged above the bracket, a hydraulic plate is fixedly arranged above the support plate, an upper assembly is arranged below the hydraulic plate, a lower mold is fixedly arranged above the bracket, conveyor belts are symmetrically arranged on one side above the bracket, a moving device is fixedly arranged on the surface of the lower mold, an adsorption device is movably arranged on the surface of the moving device, and a cooling device is fixedly arranged below the adsorption device.

[0005] Furthermore, a water storage tank is arranged on the inner wall of the bracket.

[0008] Furthermore, the adsorption device includes an adsorption slide rail fixedly installed above the moving slide plate, an adsorption motor is fixedly arranged on one side of the adsorption slide rail, an adsorption threaded rod is adapted to be arranged at the output end of the adsorption motor, an adsorption slide plate is threadedly adapted to be arranged on the surface of the adsorption threaded rod, a concave plate is fixedly arranged on one side of the adsorption slide plate, negative pressure plates are fixedly arranged at both ends of the concave plate, and negative pressure suction cups are symmetrically arranged at both ends of the negative pressure plates.

[0009] Furthermore, the cooling device includes a cooling cylinder fixedly installed on the inner wall of the lower mold and a cooling plate fixedly installed below the adsorption slide rail; One side below the cooling plate is fixedly provided with a telescopic push rod, one end of the telescopic push rod is fixedly provided with a negative pressure water absorption plate, the negative pressure water absorption plate is movably adapted to the inner wall of the cooling cylinder, the other end of the cooling cylinder is fixedly provided with a cooling pipe, circulating water pipes are symmetrically arranged at one end of the cooling pipe, a water suction pipe is fixedly arranged below the cooling cylinder, and the circulating water pipes and the water suction pipe penetrate and extend into the water storage tank.

[0010] Furthermore, a preparation process of an injection mold base for automobile headlamp production includes the following steps: S1: Turn on the control device, control the operation of the hydraulic telescopic rod, and make the hydraulic telescopic rod push the upper mold to descend until the upper mold is in close contact with the lower mold. Then, perform an injection molding operation inside the mold to start the production of automotive headlights; S2: During the descent of the upper mold, the transmission plate below it also descends, and the toothed plate on one side of the transmission plate descends synchronously. The toothed plate drives the moving gear meshed with it to rotate, and the rotation of the moving gear drives the moving threaded rod to rotate. The rotation of the moving threaded rod causes the moving slide plate with a surface thread fit to move along the moving slide rail, thereby driving the adsorption device to move out between the upper mold and the lower mold to avoid affecting the close contact of the mold; S3: At the same time, when the transmission plate descends, it drives the lifting plate to move downward, and the lifting plate drives the lifting telescopic rod to stretch, so that the ejector plate is at the bottom of the inner groove of the lower mold; S4: After injection molding is completed, control the hydraulic telescopic rod to raise the upper mold. The rise of the upper mold drives the transmission plate to rise, the rise of the transmission plate drives the toothed plate to rise, the toothed plate drives the moving gear to rotate in the reverse direction, and further causes the moving threaded rod to rotate in the reverse direction. The moving threaded rod drives the moving slide plate to move in the reverse direction, and the moving slide plate drives the adsorption device to move to the middle of the mold; S5: When the transmission plate rises, the lifting telescopic rod shortens and pushes the ejector plate to rise in the inner groove of the lower mold to eject the injection-molded headlights from the lower mold; S6: Start the adsorption motor. The adsorption motor drives the adsorption threaded rod to rotate. The adsorption threaded rod causes the adsorption slide plate with a surface thread fit to move along the adsorption slide rail. The adsorption slide plate drives the concave plate, the negative pressure plate, and the negative pressure suction cup to move to a suitable position, and adsorb the injection-molded headlights through the negative pressure suction cup; S7: Control the hydraulic telescopic rod again to lower the upper mold. During the descent of the upper mold, it drives the transmission plate to descend, and repeat step S2 to make the adsorption device carry the headlights out of the mold area. When the adsorption device moves to the outermost position, cancel the adsorption of the negative pressure suction cup, place the headlights on the surface of the conveyor belt, and the conveyor belt transports the headlights to the next process; S8: During the movement of the adsorption device, drive the cooling device below to work. When the adsorption device moves to the outside, drive the telescopic push rod to stretch, so that the negative pressure water absorption plate is at one end of the cooling cylinder. At this time, pump water from the water storage tank into the cooling cylinder through the water suction pipe; when the adsorption device moves into the mold after injection molding is completed, drive the telescopic push rod to shorten and move, so that the negative pressure water absorption plate is at the other end of the cooling cylinder, and drain the water in the cooling cylinder into the circulating water pipe to replace the hot water after each injection molding to complete the cooling cycle; S9: Repeat the above steps S1 - S8 to realize the overall cyclic operation of the device and continuously produce automotive headlights.

[0011] The beneficial effects of this technical solution are: (1) Through the transmission structure of the upper component, the adsorption device is automatically moved out of the mold area during injection molding, automatically moved in and precisely adsorbs the car lamp after injection molding is completed, and finally automatically moved out and placed on the conveyor belt. The entire process does not require manual intervention, reducing the time and labor intensity of manual operation, greatly improving production efficiency. Compared with the traditional manual picking method, the production cycle can be significantly shortened, and the product output per unit time is increased; During the process of manual picking, due to the uncertainty of operation and human factors, it is easy to cause damage such as scratches and deformation to the car lamp products after injection molding. However, in the automated picking method of the present invention, each component operates precisely according to the preset program and trajectory, which can avoid damage to the products caused by improper manual operation, ensuring the appearance quality and performance stability of the products.

[0012] (2) The cooling device is driven by the movement of the adsorption device, cleverly realizing the extraction and discharge cycle of water in the cooling cylinder, effectively cooling the mold. During the injection molding process, the mold will heat up due to the high-temperature injection molding raw materials. Excessive temperature will affect the molding quality of the car lamp, such as defects like deformation and bubbles. The cooling system of the present invention can timely take away the heat of the mold, keeping the mold within a suitable temperature range and ensuring the stable molding quality of the car lamp; The design of the water storage tank and the circulating water pipe realizes the recycling of water resources, reduces the dependence on external water sources, and saves water resources. At the same time, the operation of the cooling system does not require additional power equipment, but only relies on the movement of the adsorption device to drive, reducing energy consumption and lowering production costs.

[0013] (3) Through the structural design of the mold base, the various processes such as injection molding, ejection, adsorption, and cooling are closely coordinated. The up and down movement of the upper mold not only controls the injection molding process but also synchronously drives the operation of the moving device, the jacking device, and the cooling device. The cooperation between the processes is tacit, without the need for frequent manual intervention and adjustment, greatly improving the automation degree of the overall production process; Enhance production stability: Since the coordinated operation between the processes is based on the mechanical structure and the preset program, its operation has high stability and reliability. Compared with the traditional mold base, it reduces production failures and product quality problems caused by factors such as poor process connection and human operation errors, ensuring the continuity of the production process and the consistency of product quality.

The lower mold 302 is firmly installed at the lower end of the hydraulic telescopic rod 301, usually by bolt connection or tenon and mortise fit plus bolt fastening to ensure that there is no relative displacement between the two. The transmission plate 303 is fixed below the lower mold 302 by welding or bolts and moves synchronously with the lower mold 302. The toothed plate 304 is fixed on one side of the transmission plate 303 by welding or bolts to ensure that it moves together with the transmission plate 303 and accurately transmits power. The jacking plate 305 is installed below the transmission plate 303 by bolt connection, and the jacking telescopic rods 306 are symmetrically fixed on the surface of the jacking plate 305 by bolts. The ejector plate 307 is connected to the moving end of the jacking telescopic rod 306 by threaded connection or pin connection to achieve a stable ejection action under the action of the jacking telescopic rod 306; The hydraulic telescopic rod 301 serves as a power source. After being powered on, the internal hydraulic system operates, pushing the telescopic rod to extend or retract, thereby driving the upper mold 302 to move up and down, achieving the opening and closing actions of the mold, meeting the requirements of the injection molding process. The transmission plate 303 moves along with the movement of the upper mold 302. Its main function is to convert the up-and-down movement of the upper mold 302 into the power input of other components. The toothed plate 304 moves synchronously with the transmission plate 303. By meshing with the moving gear 602, it converts the linear motion into rotational motion, thereby driving the moving device 6 to work. The lifting system composed of the lifting plate 305 and the lifting telescopic rod 306. When the transmission plate 303 descends, the lifting telescopic rod 306 elongates, sending the ejector plate 307 to the bottom of the inner groove of the lower mold 4; when the transmission plate 303 ascends, the lifting telescopic rod 306 shortens, pushing the ejector plate 307 to eject the injection-molded vehicle lamp from the lower mold 4, facilitating subsequent part-taking operations; The moving device 6 includes a moving slide rail 601 fixedly installed on the surface of the lower mold 4. One end of the moving slide rail 601 is provided with a moving gear 602, which is adaptively meshed with the toothed plate 304. A moving threaded rod 603 is fixedly provided at the axial center position on one side of the moving gear 602, and a moving slide plate 604 is threadedly adapted to the surface of the moving threaded rod 603; The moving slide rail 601 is fixed on the surface of the lower mold 4 by bolts or welding, providing an accurate moving track for the moving slide plate 604. The moving gear 602 is installed on the shaft at one end of the moving slide rail 601, and the shaft is connected to the moving slide rail 601 through a bearing, ensuring that the moving gear 602 can rotate flexibly. One end of the moving threaded rod 603 is key-connected to the moving gear 602 at the axial center position to ensure synchronous rotation of the two; the other end of the moving threaded rod 603 is installed on the other side of the moving slide rail 601 through a bearing to ensure its stable rotation. The moving slide plate 604 is threadedly connected to the moving threaded rod 603 and is connected to the moving slide rail 601 through a slider at the bottom, enabling the moving slide plate 604 to slide smoothly on the moving slide rail 601; When the toothed plate 304 moves up and down with the transmission plate 303, the moving gear 602 meshed with the toothed plate 304 will rotate accordingly. The rotation of the moving gear 602 drives the moving threaded rod 603 key-connected to it to rotate synchronously. Since the moving slide plate 604 is threadedly connected to the moving threaded rod 603 and is restricted by the moving slide rail 601, the rotation of the moving threaded rod 603 will be converted into the linear movement of the moving slide plate 604 on the moving slide rail 601. Its functional role is to move the adsorption device 7 out between the upper mold 302 and the lower mold 4 during the injection molding process to avoid affecting the normal mold closing; after the injection molding is completed, move the adsorption device 7 to the middle of the mold to facilitate the adsorption operation of the injection-molded vehicle lamp; The adsorption device 7 includes an adsorption slide rail 701 fixedly installed above the moving slide plate 604. An adsorption motor 702 is fixedly provided on one side of the adsorption slide rail 701. An adsorption threaded rod 703 is adaptively provided at the output end of the adsorption motor 702. An adsorption slide plate 704 is threadedly adapted to the surface of the adsorption threaded rod 703. A concave plate 705 is fixedly provided on one side of the adsorption slide plate 704. Negative pressure plates 706 are fixedly provided at both ends of the concave plate 705. Negative pressure suction cups 707 are symmetrically provided at both ends of the negative pressure plates 706; The adsorption slide rail 701 is fixed above the moving slide plate 604 by bolts, providing a moving track for the adsorption slide plate 704. The adsorption motor 702 is installed on one side of the adsorption slide rail 701 by bolts, and its output shaft is connected to the adsorption threaded rod 703 through a coupling to ensure stable power transmission. Both ends of the adsorption threaded rod 703 are installed on the adsorption slide rail 701 through bearings to ensure its smooth rotation. The adsorption slide plate 704 is threadedly connected to the adsorption threaded rod 703 and is connected to the adsorption slide rail 701 through a slider at its bottom, enabling the adsorption slide plate 704 to slide smoothly on the adsorption slide rail 701. The concave plate 705 is fixed on one side of the adsorption slide plate 704 by welding or bolt connection. The negative pressure plates 706 are bolted to both ends of the concave plate 705. The negative pressure suction cups 707 are symmetrically installed at both ends of the negative pressure plates 706, usually by threaded connection or clamping, which is convenient for installation and replacement; After the adsorption motor 702 is powered on, its output shaft drives the adsorption threaded rod 703 to rotate. Since the adsorption slide plate 704 is threadedly connected to the adsorption threaded rod 703 and is restricted by the adsorption slide rail 701, the rotation of the adsorption threaded rod 703 causes the adsorption slide plate 704 to move linearly on the adsorption slide rail 701. The adsorption slide plate 704 drives the concave plate 705, the negative pressure plates 706, and the negative pressure suction cups 707 to move to a suitable position. The negative pressure plates 706 and the negative pressure suction cups 707 generate negative pressure through the internal vacuum system to adsorb the injection-molded headlights, realizing the automatic part-taking function, taking out the headlights from the mold and transferring them to the designated position; The cooling device 8 includes a cooling cylinder 801 fixedly installed on the inner wall of the lower mold 4 and a cooling plate 802 fixedly installed below the adsorption slide rail 701; A telescopic push rod 803 is fixedly provided on one side below the cooling plate 802. One end of the telescopic push rod 803 is fixedly provided with a negative pressure water-absorbing plate 804. The negative pressure water-absorbing plate 804 is movably adapted to the inner wall of the cooling cylinder 801. The other end of the cooling cylinder 801 is fixedly provided with a cooling pipe 805. One end of the cooling pipe 805 is symmetrically provided with circulating water pipes 806. A water suction pipe 807 is fixedly provided below the cooling cylinder 801. The circulating water pipes 806 and the water suction pipe 807 penetrate and extend into the water storage tank 101; The cooling cylinder 801 is fixed to the inner wall of the lower mold 4 by welding or bolting, and is used to store and circulate cooling water. The cooling plate 802 is installed below the adsorption slide rail 701 by bolting, and moves with the adsorption device 7. One end of the telescopic push rod 803 is bolted to one side below the cooling plate 802, and the other end is bolted to the negative pressure water absorption plate 804. One end of the cooling pipe 805 is welded or sealed to the cooling cylinder 801, and the other end is connected to the circulating water pipe 806 through a three-way joint. One end of the water absorption pipe 807 is sealed to the bottom of the cooling cylinder 801, and the other end extends into the water storage tank 101 through a pipe joint. When the adsorption device 7 moves, the cooling plate 802 is driven to move synchronously, and the telescopic push rod 803 under the cooling plate 802 is extended or shortened according to the position change of the adsorption device 7. When the adsorption device 7 moves to the outside, the telescopic push rod 803 is extended, so that the negative pressure water absorption plate 804 is at one end of the cooling tube 801. At this time, water is pumped from the water storage tank 101 into the cooling tube 801 by negative pressure through the water absorption pipe 807; when the adsorption device 7 is moved into the mold after the injection molding is completed, the telescopic push rod 803 is shortened and moved, so that the negative pressure water absorption plate 804 is at the other end of the cooling tube 801, and the water in the cooling tube 801 is discharged into the circulating water pipe 806 through the cooling pipe 805, so as to realize the circulating cooling of the mold. Its function is to take away the heat generated by the mold in the injection molding process after each injection molding is completed, to ensure that the temperature of the mold is within a suitable range, to improve the molding quality of the headlights, and at the same time to reduce energy consumption and production costs through the recycling of water resources.

[0018] Embodiment 2: See also Figure 1-7 The present invention provides a technical solution: a preparation process of an injection mold frame for automobile lamp production, characterized in that it includes the following steps: S1: Turn on the control device to control the hydraulic telescopic rod 301 to operate, so that the hydraulic telescopic rod 301 pushes the upper mold 302 to move downward until the upper mold 302 is tightly fitted with the lower mold 4, and then performs injection molding in the mold to start the production of automobile lamps; S2: When the upper mold 302 descends, the transmission plate 303 below it descends accordingly, and the tooth plate 304 on one side of the transmission plate 303 descends synchronously. The tooth plate 304 drives the movable gear 602 meshing therewith to rotate, and the rotation of the movable gear 602 drives the movable threaded rod 603 to rotate. The rotation of the movable threaded rod 603 causes the movable slide plate 604 with the threaded surface to move along the movable slide rail 601, thereby driving the adsorption device 7 to move out from between the upper mold 302 and the lower mold 4 to avoid affecting the close fit of the molds. S3: At the same time, the transmission plate 303 moves downward, driving the lifting plate 305 to move downward, and the lifting plate 305 drives the lifting telescopic rod 306 to lengthen, so that the ejection plate 307 is at the bottom of the inner groove of the lower mold 4; S4: After the injection molding is completed, control the hydraulic telescopic rod 301 to raise the upper mold 302. The rising of the upper mold 302 drives the transmission plate 303 to rise. The rising of the transmission plate 303 drives the toothed plate 304 to rise. The toothed plate 304 drives the moving gear 602 to rotate in the reverse direction, thereby causing the moving threaded rod 603 to rotate in the reverse direction. The moving threaded rod 603 drives the moving slide plate 604 to move in the reverse direction. The moving slide plate 604 drives the adsorption device 7 to move to the middle of the mold. S5: When the transmission plate 303 rises, the jacking telescopic rod 306 shortens and pushes the ejector plate 307 to rise in the inner groove of the lower mold 4, ejecting the injection-molded car headlight from the lower mold 4. S6: Start the adsorption motor 702. The adsorption motor 702 drives the adsorption threaded rod 703 to rotate. The adsorption threaded rod 703 causes the adsorption slide plate 704 with a surface thread fit to move along the adsorption slide rail 701. The adsorption slide plate 704 drives the concave plate 705, the negative pressure plate 706, and the negative pressure suction cup 707 to move to the appropriate positions, and adsorbs the injection-molded car headlight through the negative pressure suction cup 707. S7: Control the hydraulic telescopic rod 301 again to lower the upper mold 302. During the lowering process of the upper mold 302, it drives the transmission plate 303 to lower. Repeat step S2 to enable the adsorption device 7 to carry the car headlight out of the mold area. When the adsorption device 7 moves to the outermost position, cancel the adsorption of the negative pressure suction cup 707, place the car headlight on the surface of the conveyor belt 5, and the conveyor belt 5 transports the car headlight to the next process. S8: During the movement of the adsorption device 7, drive the cooling device 8 below to work. When the adsorption device 7 moves to the outside, drive the telescopic push rod 803 to elongate, so that the negative pressure water absorption plate 804 is at one end of the cooling cylinder 801. At this time, pump water from the water storage tank 101 into the cooling cylinder 801 through the water suction pipe 807. When the adsorption device 7 moves into the mold after the injection molding is completed, drive the telescopic push rod 803 to shorten and move, so that the negative pressure water absorption plate 804 is at the other end of the cooling cylinder 801, and drain the water in the cooling cylinder 801 into the circulating water pipe 806 to replace the hot water after each injection molding, completing the cooling cycle. S9: Repeat the above steps S1 - S8 to achieve the overall cyclic operation of the device and continuously produce automotive headlights.

[0019] Working principle: When this injection mold frame for automotive headlight production works, the bracket 1 serves as a stable basic support, bearing the weight of the entire device and maintaining its stability. The support plate 2 and the hydraulic plate 201 are firmly connected by bolts or other means, providing a reliable installation platform for the upper assembly 3. After starting the equipment, the control device starts the hydraulic telescopic rod 301. The hydraulic telescopic rod 301 utilizes the internal hydraulic system to work and pushes the upper mold 302 to move downward until it is tightly closed with the lower mold 4. At this time, the injection molding machine injects the injection molding raw material into the mold cavity, starting the injection molding process of the car headlight. In this process, the movement of the upper mold 302 drives a series of linkage reactions. Since the transmission plate 303 is fixedly connected to the upper mold 302, when the upper mold 302 descends, the transmission plate 303 descends synchronously. The toothed plate 304 on one side of the transmission plate 303 also moves accordingly. The toothed plate 304 meshes with the moving gear 602, and the linear motion of the toothed plate 304 is converted into the rotational motion of the moving gear 602. The rotation of the moving gear 602 drives the moving threaded rod 603 to rotate through a key connection. The moving threaded rod 603 is threadedly connected to the moving slide plate 604, and the moving slide plate 604 is constrained by the moving slide rail 601. Therefore, the rotation of the moving threaded rod 603 causes the moving slide plate 604 to slide on the moving slide rail 601, thereby driving the adsorption device 7 out of the space between the upper and lower molds, avoiding affecting the mold clamping. At the same time, when the transmission plate 303 descends, it drives the jacking plate 305 to move downward, and the jacking telescopic rods 306 symmetrically arranged on the surface of the jacking plate 305 are elongated, so that the ejector plate 307 reaches the bottom of the inner groove of the lower mold 4, preparing for ejecting the injection-molded lamp in the subsequent process; After the injection molding is completed, the control device causes the hydraulic telescopic rod 301 to contract, and the upper mold 302 rises. Similarly, components such as the transmission plate 303, the toothed plate 304, the moving gear 602, the moving threaded rod 603, and the moving slide plate 604 operate according to the opposite motion logic when descending. Finally, the adsorption device 7 moves to the middle of the mold. At this time, the transmission plate 303 rises to drive the jacking telescopic rod 306 to shorten, and the jacking telescopic rod 306 pushes the ejector plate 307 to rise, ejecting the injection-molded lamp from the inner part of the lower mold 4; Immediately afterwards, the adsorption motor 702 is started. The output shaft of the adsorption motor 702 drives the adsorption threaded rod 703 to rotate through a coupling. The adsorption threaded rod 703 is threadedly connected to the adsorption slide plate 704, and the adsorption slide plate 704 is constrained by the adsorption slide rail 701. Thus, the adsorption slide plate 704 slides on the adsorption slide rail 701, and the adsorption slide plate 704 drives the concave plate 705, the negative pressure plate 706, and the negative pressure suction cup 707 to move to a suitable position. The vacuum system inside the negative pressure plate 706 and the negative pressure suction cup 707 generates negative pressure to adsorb the ejected lamp; Subsequently, the hydraulic telescopic rod 301 is controlled again to make the upper mold 302 descend, repeating the process of the adsorption device 7 moving out of the mold area. When the adsorption device 7 moves to the outermost position, the adsorption of the negative pressure suction cup 707 is cancelled, and the lamp is placed on the conveyor belt 5, and the conveyor belt 5 transports the lamp to the next process; During the whole process, the movement of the adsorption device 7 also drives the cooling device 8 to work. When the adsorption device 7 moves to the outside, the telescopic push rod 803 below the cooling plate 802 elongates, so that the negative pressure water absorption plate 804 is at one end of the cooling cylinder 801, and water is pumped from the water storage tank 101 to the inside of the cooling cylinder 801 through the water suction pipe 807; when the adsorption device 7 moves into the mold, the telescopic push rod 803 shortens, so that the negative pressure water absorption plate 804 is at the other end of the cooling cylinder 801, and the water in the cooling cylinder 801 is discharged into the circulating water pipe 806 through the cooling pipe 805 to cool the mold in a cycle, timely taking away the heat generated during the injection molding process, ensuring that the mold temperature is appropriate, improving the forming quality of the car headlight, and repeating this cycle to achieve the efficient and high-quality production of the car headlight.
