Description

[0001] The invention relates to the technical field of automobile molds, in particular to an automobile injection mold for parts processing. Background Art

[0002] As the foundation of the automotive industry, auto parts are an essential factor in supporting the sustainable and healthy development of the automotive industry. Most auto parts are still produced by injection molding. Plastic particles are placed in the feeding chamber of the injection molding machine and gradually melted by the heating system to become liquid plastic. With the strong pressure generated by the screw or plunger, the high-pressure melt is accurately pressed into the mold cavity and enters the pressure holding and cooling stage to ensure that the plastic fills the mold cavity without dead ends. After cooling, it hardens and forms. The mold is opened, and the molded plastic parts are pushed out to complete the injection molding process; When the existing injection mold is used, the upper mold group and the lower mold are generally combined first, and then the injection liquid is injected. In actual production, since most molds do not have an anti-overflow glue mechanism, when there is too much injection liquid in the mold, it is easy to overflow, which not only affects the stability of the mold, resulting in a decrease in the injection molding quality of the mold, but also easily causes a waste of injection liquid; In view of this, the present invention proposes an automobile injection mold for parts processing to make up for and improve the deficiencies of the prior art.

[0018] The working principle and use process of the present invention: In order to facilitate the description and understanding of this working process, the injection molding state and the demoulding state are mainly used to describe and explain: In the demoulding state: the staff drives the double-axis motor 31 from the control panel to start, so that the main rotating rod 32 and the auxiliary rotating rod 41 rotate clockwise. Since the top of the main rotating rod 32 is fixedly connected to the main rotating wheel 314, the liquid storage hole 39 is slidably connected to the heat transfer plug 38, the center of the heat transfer plug 38 is threadedly connected to the main threaded rod 36, the top of the liquid storage hole 39 is connected to the liquid guide tube 310, and the auxiliary turntable 35 and the main turntable 33 are connected to the first belt 34, the outer surface of the main threaded rod 36 is rotatably connected to the heat supply plate 37, the liquid storage hole 39 is provided with a straight supply slide groove, and the heat transfer plug 38 is fixedly connected to the main threaded rod 36.

At the same time, since the secondary threaded rod 317 is threadedly connected to the supply and transfer platform 7, the bottom end of the secondary threaded rod 317 is fixedly connected to the secondary rotating wheel 316, and the secondary rotating wheel 316 and the main rotating wheel 314 are connected to the second belt 315 by transmission, and the supporting rod 6 and the supply and transfer platform 7 are matched and limited, so that the secondary threaded rod 317 is rotated to control the upper mold base 1 to move upward, so that the upper mold base 1 moves upward and separates from the lower mold base 2; In the injection molding state: inversely deduced from the above working process, the staff controls the dual-axis motor 31 to make the main rotating rod 32 and the auxiliary rotating rod 41 rotate counterclockwise until the heat-conducting plug 38 moves downward and is level with the inner bottom surface of the lower mold base 2, and the upper mold base 1 moves downward and engages with the lower mold base 2. At the same time, since the bottom end of the auxiliary rotating rod 41 is fixedly connected to the cam 42, one end of the cam 42 is rotatably connected to the push rod 43, and an air inlet hole 47 is provided on the air supply cylinder 45, the inner wall of the air supply cylinder 45 is slidably connected to the piston block 44, and the piston block 44 is fixedly connected to the push rod 43, so that the piston block 44 is located in the air supply cylinder 45 with the rotation of the auxiliary rotating rod 41, and intermittently reciprocates horizontally, so that the external air is pressurized through the air inlet hole 47 and transported to the heat dissipation through hole 48, so as to dissipate heat from the mold cavity of the lower mold base 2; During the process of converting from the demoulding state to the injection state, as the heat conductive plug 38 moves upward, the overflowed injection liquid stored in the liquid guide tube 310 is guided to the liquid storage hole 39 for storage, and the steering ring 311 carries the positive magnetic block 312 and the negative magnetic block 313 to continuously rotate, so that the positive magnetic block 312 and the negative magnetic block 313 magnetically cut the heat supply plate 37, so that the heat supply plate 37 generates heat to heat the injection liquid.
