Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a molding mold for automobile injection molded parts. Background Art

[0002] Automotive injection molding molds are tools used to produce automotive parts during the automobile manufacturing process. Automotive injection molding parts are usually made of materials such as plastic or rubber. These materials are injected into the molding mold after heating and formed into the desired shape after cooling. In this way, most parts such as automobile body parts, interior parts, engine parts, etc. can be completed.

[0003] After searching, the patent number "CN218342717U" mentioned in the text that "a rapid heat dissipation mold for automobile injection molding production includes a box body; a water tank is fixedly connected to the bottom of the inner wall of the box body; a water pump is fixedly connected to one side of the water tank, and a cooling pipe is fixedly connected to the other end of the water pump; a one-way valve is fixedly connected to the end of the cooling pipe away from the water pump, and the other end of the one-way valve is fixedly connected to the outside of the water tank; a fan blade is rotatably connected to the inner wall of one side of the box body adjacent to the cooling pipe; water in the water tank is pumped out by the water pump and flows into the cooling pipe to realize heat transfer, and the air flow in the box is accelerated by starting the fan blade to rotate, and the air inside and outside the box is exchanged through the fan slot and the heat dissipation slot, realizing The function of quickly cooling the mold during the production of automobile injection molding parts is realized. When in use, the water in the water tank is pumped out by a water pump and flows into the cooling pipe to realize heat transfer. The air flow in the box is accelerated by starting the fan blades to rotate. The air inside and outside the box interacts through the fan slot and the heat dissipation slot, realizing the function of quickly cooling the mold during the production of automobile injection molding parts. However, when installing the upper mold, the screw needs to be rotated four times to fix the position of the upper mold, which takes a long time. In addition, the lower mold is only placed in the interior of the slide slot through the fixing rod, and is not fixed. As a result, the relative position of the lower mold and the upper mold is easily offset during use, resulting in the inability to perform injection molding.

[0004] Therefore, we provide automotive injection molding molds to solve the above problems. Utility Model Content

[0029] The clamping assembly 9 includes a threaded rod 91, a turntable 92, a linkage rod 93, an adjusting rod 94 and a clamping plate 95.

[0030] Furthermore, a groove 921 is provided on the surface of the turntable 92, and the groove 921 is designed in a regular hexagonal shape. Through the setting of the turntable 92, the threaded rod 91 can be rotated better.
