[0024] By adopting the above technical solution, the molten raw materials required for the injection molding of the automobile lampshade are injected into the filter cartridge 13 through the through hole 11, and then the rotating part 15 is used to drive the top plate 12 to rotate, and the rotation of the top plate 12 drives the filter cartridge 13 to rotate. During the rotation of the filter cartridge 13, the falling rate of the raw materials inside the filter cartridge 13 can be accelerated, and during the falling process of the raw materials, the filter screen 14 can filter and remove impurities from the raw materials, thereby ensuring the cleanliness of the injection-molded raw materials, and thus ensuring the quality of the subsequently injection-molded automobile lampshade and the subsequent use effect of the automobile lampshade.

During the cooling and molding process, the cooling mechanism 3 can accelerate the cooling and molding efficiency of the automobile lampshade inside the upper mold 6 and the lower mold 5. Example 2

[0030] The present embodiment differs from the embodiment 1 in that the support assembly 7 includes a support rod 71, an end plate 72, a fixing screw 73, a fixing nut 74, a reset member 75 and a support block 76. Both sides of the lower mold 5 are fixedly connected to the support rod 71. A support block 76 is inserted into the interior of the support rod 71. A reset member 75 is provided between the support rod 71 and the support block 76. One end of the support block 76 is fixedly connected to the end plate 72. A fixing screw 73 is fixedly connected to the side wall of the support rod 71. A circular hole is opened on the end plate 72 at the position corresponding to the fixing screw 73.

[0033] When this embodiment is used, after the automobile lampshade is cooled and formed, the upper mold 6 is moved upward, and then the support block 76 is moved toward the upper mold 6. The movement of the support block 76 drives the moving block 753 to move inside the moving groove 751 and the end plate 72 to move. The movement of the moving block 753 drives the return spring 752 to stretch. When the end plate 72 moves to fit the side wall of the support rod 71, the fixing nut 74 is rotated and screwed onto the fixing screw 73, and made to fit the side wall of the end plate 72. The support block 76 can be used to support the upper mold 6, which is convenient for the staff to take out the cooled and formed automobile lampshade from the lower mold 5.

[0034] The rotary motor 155 in the present invention is an existing disclosed technology, and the selected model is TCB6334.

[0035] The structure and principle of the cooling mechanism 3 composed of a water tank, a heat dissipation box, a ventilation net, a water inlet pipe, a transmission belt, a water outlet pipe, a water pump, a motor, a mounting plate, a pulley, a transmission rod, a stirring plate, a stirring rod, a chute, a moving block, a slider, a heat dissipation fan, a threaded rod, a cooling pipe, an outlet pipe, a cooling chamber, and an inlet pipe in the utility model have been disclosed in a car lampshade mold with a circulating cooling structure disclosed in Chinese patent application No. 202220742108.8. Its working principle is as follows: the upper end of the base 4 is connected to a water tank, the top of the water tank is connected to a heat dissipation box, a ventilation net is installed on one side of the top of the water tank, and a water adding cover is movably connected to the other side of the water tank, one end of the water tank is connected to a water pump, and the end of the water pump facing away from the water tank is connected to the water outlet pipe, and the water tank One end of the water tank is connected to the water inlet pipe, and one end of the water tank and the radiator box are both interspersed with a transmission rod, one end of the two transmission rods is connected to a pulley, and the outer surfaces of the two pulleys are jointly sleeved with a transmission belt, the lower end of one water tank is connected to a mounting plate, the top of the mounting plate is connected to a motor, and the output end of the motor is fixedly connected to one of the pulleys. One end of the transmission rod inserted at one end of the water tank extends into the water tank and is connected to a stirring rod, and both ends of the stirring rod are connected to multiple stirring plates, one end of the transmission rod inserted and connected to one end of the radiator box extends into the radiator box and is connected to a threaded rod, and the end of the threaded rod away from the transmission rod is rotatably connected to one side inner wall of the radiator box, and the outer surface of the threaded rod is sleeved with a moving block, and a slide groove is provided on the upper inner wall of the radiator box, and a slider is slidably connected in the slide groove. The lower end of the block is fixedly connected to the moving block, and the lower end of the moving block is connected to a heat dissipation fan. The lower end of the heat dissipation box and the top of the water tank are provided with through slots for use with the heat dissipation fan. A cooling chamber is provided inside the lower mold 5, and a cooling pipe is provided in the cooling chamber. One end of the cooling pipe is connected to an inlet pipe, and the other end of the cooling pipe is connected to an outlet pipe. The inlet pipe is fixedly connected to the water outlet pipe, and the outlet pipe is fixedly connected to the water inlet pipe. When in use, the water pump is started to start the water pump to extract the cooling water in the water tank and send it into the lower mold 5 through the outlet pipe. After cooling, the used cooling water will flow back to the water tank through the water inlet pipe. In order to quickly cool down the used cooling water, the motor on the mounting plate can be started to drive one of the pulleys to rotate. Under the action of the pulley, the other pulley will also start to rotate, causing the two transmission rods to start rotating at the same time. When the transmission rod connected to the water tank rotates, it will drive the stirring rod in the water tank to rotate, causing the stirring plate to rotate accordingly to stir the cooling water. With the cooperation of the ventilation network, the cooling water can be cooled. When cooling the cooling water after use, the cooling fan in the heat dissipation box can be started, and the cooling fan can cooperate with the stirring rod and the stirring plate to cool the cooling water. When the two pulleys rotate, the transmission rod connected to the heat dissipation box will drive the threaded rod in the heat dissipation box to rotate, causing the moving block to start moving along the threaded rod, thereby causing the cooling fan to move accordingly, thereby increasing the speed of cooling water when cooling.When the moving block moves, the slider will also slide in the chute, making the movement of the moving block more stable. When cooling the injection molded parts, the cooling water from the outlet pipe will enter the cooling pipe through the inlet pipe. The cooling water will flow in the cooling pipe to cool the injection molded parts. After that, the cooling water from the cooling pipe will enter the water inlet pipe through the outlet pipe and return to the water tank to complete the cooling process of the injection molded parts.

[0036] The working principle and use process of the present invention are as follows: the present invention injects the molten raw materials required for the injection molding of automobile lampshades into the filter cartridge 13 through the through hole 11, and then starts the rotating motor 155 on the mounting block 154. The operation of the rotating motor 155 drives the rotating gear 151 to rotate, and the rotation of the rotating gear 151 drives the built-in gear ring 153 to rotate. The rotation of the built-in gear ring 153 drives the rotating frame 152 to rotate, and the rotation of the rotating frame 152 drives the top plate 12 to rotate. The rotation of the top plate 12 drives the filter cartridge 13 to rotate, which can accelerate the falling rate of the raw materials inside the filter cartridge 13. During the falling process of the raw materials, the filter screen 14 can filter and remove impurities from the raw materials to ensure the cleanliness of the raw materials for injection molding, thereby ensuring the quality of the subsequent injection-molded automobile lampshades and the subsequent use effect of the automobile lampshades. The filtered and impurity-removed raw materials are injected into the space between the upper mold 6 and the lower mold 5 through the injection molding tube 2 for cooling and molding operations. During the cooling and molding process, the cooling mechanism 3 can accelerate the cooling and molding efficiency of the automobile lampshade inside the upper mold 6 and the lower mold 5. After the automobile lampshade is cooled and molded, the upper mold 6 is moved upward, and then the support block 76 is moved toward the upper mold 6. The movement of the support block 76 drives the moving block 753 to move inside the moving groove 751 and the end plate 72 to move. The movement of the moving block 753 drives the reset spring 752 to stretch. When the end plate 72 moves to fit the side wall of the support rod 71, the fixing nut 74 is rotated and screwed onto the fixing screw 73, and it is fit to the side wall of the end plate 72. The support block 76 can be used to support the upper mold 6, which is convenient for the staff to take out the cooled and molded automobile lampshade from the inside of the lower mold 5.
