Description

TECHNICAL FIELD

[0001] The application relates to the technical field of injection molds, in particular to an automobile part injection device facilitating material stripping. BACKGROUND

[0002] Automobile parts are units that constitute an automobile as a whole and products serving the automobile. Automobile parts are various, and with the improvement of people's living standards, people's consumption of automobiles is also increasing, and the market for automobile parts is also becoming larger. In recent years, automobile parts manufacturers have also been developing rapidly. In the prior art, most automobile parts are made by injection molding.

[0003] In the prior art, a kind of injection mold that can be quickly cooled and demolded is disclosed in Chinese patent CN108582637A. The first electric telescopic rod can make the movable template slide inside the support frame, thereby facilitating the demolding of the molded mold, improving the working efficiency of the injection mold. The second electric telescopic rod is also provided on the device, which can make the auxiliary demolding rod and the main demolding rod move inside the limiting cover, thereby assisting the demolding of the molded model through the auxiliary demolding rod and the main demolding rod, ensuring that the molded model can be quickly demolded, improving the working efficiency of the entire device, solving the problem that the existing injection molding device cannot efficiently injection mold, thereby reducing the working efficiency of the injection mold.

[0004] However, the prior art still has some shortcomings, such as:

[0005] During injection molding of automobile parts, an injection mold is usually used. The injection mold is used to inject molten plastic into the mold cavity under high pressure by an injection molding machine, and the molded product is obtained after cooling and solidification. During the cooling process, the most commonly used method is to use water cooling or air cooling to accelerate the cooling of the mold, thereby improving the molding efficiency of the injection mold. During air cooling, heat is removed from the mold by heat dissipation fins, and then a fan is used to dissipate heat from the heat dissipation fins, thereby accelerating the cooling of the mold by the heat dissipation fins. However, since the heat dissipation fins are exposed to the outside for a long time, a lot of dust will adhere between the heat dissipation fins, which will affect the heat dissipation effect of the heat dissipation fins. Moreover, only the air flow generated by the fan blades can remove the heat between the fan blades, and part of the heat on the heat dissipation fins cannot be removed immediately. When the mold cannot be cooled quickly at the first time, the working efficiency of the injection mold will be reduced. SUMMARY

[0061] Working principle:

[0062] In use, the first module 5 is moved horizontally by the hydraulic cylinder 4 to adhere to the second module 6. When the first module 5 moves, the sliding block 8 moves on the sliding rod 7 to ensure the stability of the first module 5 during horizontal movement. Then the first motor 11 drives the injection roller to rotate, which facilitates the injection of the injection material in the injection cavity into the mold cavity of the second module 6.

[0063] When the injection is completed, the first motor 11 is stopped. The cooling water is introduced into the cooling pipe 12 in the second module 6 through the liquid inlet pipe 14. The cooling liquid flows in the cooling pipe 12 to facilitate the removal of heat in the second module 6. The heat removed by the cooling liquid is discharged through the liquid outlet block. At the same time, the heat dissipation fins 13 on the second module 6 are used to accelerate the cooling of the second module 6.

[0064] Through the start of the second motor 23, the second motor 23 drives the driving shaft 26 to rotate. The fan blades 29 on the driving shaft 26 rotate in the fan shell 28. The airflow generated by the fan blades 29 blows against the heat dissipation fins 13. The hot air between the heat dissipation fins 13 is quickly discharged with the flow of the airflow. By accelerating the heat dissipation of the heat dissipation fins 13, the heat dissipation effect of the heat dissipation fins 13 is improved, and the molding of the injection molding part in the mold is effectively improved.

[0065] At the same time, when the cooling water enters the cooling pipe 12 through the liquid inlet pipe 14, part of the cooling water enters the flow guide pipe 35 through the connecting pipe 36. The cooling water in the flow guide pipe 35 enters the shunt pipe 31 through the flexible hose 34, and then is sprayed on the heat dissipation fins 13 through the spray head 32 on the shunt pipe 31.

[0066] When the second motor 23 drives the driving shaft 26 to rotate, the driving shaft 26 will drive the first pulley 37 to rotate synchronously, the first pulley 37 will drive the second pulley 40 to rotate through the transmission belt, the rotation of the second pulley 40 will drive the rotating shaft 39 to rotate, the reciprocating thread 41 on the rotating shaft 39 and the crescent pin 44 make the sliding block 8 slide block 43 reciprocate on the reciprocating thread 41, the sliding block 43 will drive the toothed plate 45 to reciprocate when reciprocating, through the meshing of the toothed plate 45 and the gear 42 on the rotating rod 30, the shunt pipe 31 on the rotating rod 30 will be in a state of oscillation, and the cooling water sprayed by the spray head 32 is uniformly sprayed on the cooling fins 13 through the oscillation of the shunt pipe 31.

[0067] When the injection molding of automobile parts is cooled in the second module 6, the hydraulic cylinder 4 drives the first module 5 to move away from the second module 6, and the first module 5 drives the J-shaped rod 18 into the pushing groove 17 through the through hole on the second module 6, and the pushing block 19 is moved in the pushing groove 17 through the J-shaped rod 18, at this time, the pushing block 19 drives the ejector pin 21 to push the injection molding in the second module 6 out, when new injection molding is needed, the hydraulic cylinder 4 drives the J-shaped rod 18 to move out of the pushing groove 17, and the ejector pin 21 outside the storage groove 57 is restored to the original position through the action of the first spring 22, so that the mold cavity in the second module 6 is in a complete state.
