Moreover, the excess release agent drips on the concave part 17 and will not cause pollution to the die casting environment.

[0070] In the die-casting process of automobile parts, the release agent can form an isolation film. Before the molten material is injected, the release agent will be evenly distributed on the surface of the mold cavity to form an isolation film to prevent the molten material from directly scouring the movable mold 3, thereby protecting the movable mold 3 and extending its service life; secondly, it promotes the flow of the molten material, helps the molten material to smoothly enter the mold cavity, and ensures the integrity of the filling process, which is crucial for the production of high-quality automobile parts blanks; thirdly, it is easy to demold. The use of a release agent can make it easier for the automobile parts blank to be removed from the mold after forming, reduce manual intervention, and improve production efficiency; fourthly, it improves the quality of automobile parts blanks, improves the surface finish of automobile parts blanks, reduces defects such as pores, and thus Improve the overall quality of the automobile parts blank; therefore, it is necessary not only to spray the release agent on the movable mold 3, but also to spray the release agent on the fixed mold 2, and the release agent is sprayed on the fixed mold 2 during the execution of the ejection component, that is, during the upward movement of the ejection block 20, the automobile parts blank in the fixed mold 2 is ejected from the fixed mold 2, and at the same time, the external material pump injects the spraying agent into the middle tube 21, and then discharges it from the spray hole 23 on the ejection block 20, and the release agent is sprayed during the upward and downward movement of the ejection block 20. The spraying of the release agent in the fixed mold 2 makes full use of the ejection execution action of the ejection component, and there is no need to preset the time for spraying the release agent in the fixed mold 2, which is also a way to improve the automobile parts blank;

[0071] The pusher assembly moves with the movement of the movable mold 3, that is, the pusher assembly as a whole moves synchronously with the movable mold 3. After the mold is opened, the pusher assembly pushes the automobile part blank, and at the same time, the cylinder 26 pushes the pusher plate 27 to move horizontally above the fixed mold 2. When the pusher block 20 pushes the automobile part blank to the specified position, the pusher plate 27 is close to the automobile part blank, and then the pusher plate 27 pushes the automobile part blank away from the pusher block 20, and the unloading of the automobile part blank is realized; after the unloading is completed, the pusher block 20 moves down and resets, and the cylinder 26 drives the pusher plate 27 to withdraw and reset;

[0072] The rear half of the push plate 27 is hollow inside, and through the material pipe 19 together with the external material pump, the material pump can inject the demoulding agent into the push plate 27, and then discharge it from the spray hole 23 opened on the lower surface of the push plate 27. In the process of the push plate 27 retreating, the spray hole 23 sprays the demoulding agent, and the demoulding agent is sprayed on the upper surface of the fixed mold 2, and cooperates with the spray hole 23 on the top block 20 to spray the demoulding agent on the fixed mold 2, so that the inner surface of the fixed mold 2 is evenly sprayed with the demoulding agent, which is helpful for demoulding the blank of the automobile parts and improving the quality of die casting;

[0073] After the movable mold 3 is horizontally away from the fixed mold 2, the mold opening action is realized. At this time, the automobile part blank needs to be disengaged from the top. When the movable mold 3 moves to the specified position, the connecting rod 24 will squeeze the No. 1 touch switch 28, and the No. 1 touch switch 28 is used to control the execution of the No. 2 hydraulic cylinder 22, which can ensure that the No. 2 hydraulic cylinder 22 can be executed after the movable mold 3 is completely moved to the axis, so as to prevent the No. 2 hydraulic cylinder 22 from pushing the automobile part blank, and the automobile part blank is pressed on the lower surface of the movable mold 3, causing damage to the automobile part blank and the movable mold 3; the No. 2 hydraulic cylinder 22 drives the middle tube 21 to move upward, and the upper end surface of the middle tube 21 is squeezed to the No. 2 touch switch 29, and the No. 2 touch switch 29 is used to control the execution of the cylinder 26, and the middle The upper end surface of the tube 21 triggers the No. 2 touch switch 29, and the cylinder 26 can execute the second stroke. The first stroke of the cylinder 26 is that the cylinder 26 drives the push plate 27 to approach the automobile part blank, and the second stroke of the cylinder 26 is that the push plate 27 pushes the automobile part blank on the top block 20 away from the top block 20 to realize the unloading of the automobile part blank; the setting of the No. 1 touch switch 28 and the No. 2 touch switch 29 can ensure that each step in the entire die-casting process is executed in an orderly manner, and the steps are closely matched with each other; the set convex portion 30 cooperates with the groove, which can improve the stability of the pressure between the pressure block 13 for maintaining the pre-pressure block 15, so that the downward pressure applied by the No. 1 hydraulic cylinder 12 can stably act on the pre-pressure block 15 to ensure the stability of the mold cavity.
