DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1-7 The utility model provides a technical solution: an extrusion casting device for dustproof automobile parts, including a base 1, an extrusion casting mold 2, a water inlet 3, a cooling channel 4, a water outlet 5, a fixed bracket 6, an electric telescopic rod 7, a movable push plate 8, a die 9, a fixed rod 10, a dustproof mechanism 11, a dust cover 12, a connecting plate 13, an auxiliary plate 14, an auxiliary block 15, a spring 16, a positioning plate 17, a convex block 18 and a pull rod 19.
[0033] When using the extrusion casting device for dust-proof automobile parts, Figure 1 , Figure 2 and Figure 3 As shown, an extrusion casting mold 2 is fixedly installed on the front side of the upper end of the base 1, and a water inlet 3 and a water outlet 5 are respectively arranged on the front and rear sides of the extrusion casting mold 2, and the water inlet 3 is connected to the water outlet 5 through a cooling channel 4. First, the water inlet 3 and the water outlet 5 are respectively connected and fixed to the external cooling water pipe, and then cooling water is injected into the extrusion casting mold 2, and the cooling water is passed into the cooling channel 4, so that the heat in the production extrusion casting process can be taken out, which plays a good cooling and temperature reduction role, and the cooling channel 4 is curved at the bottom of the extrusion casting mold 2, which increases the contact area between the extrusion casting mold 2 and the cooling water, thereby improving the actual cooling efficiency and playing a good protective role for the extrusion casting mold 2;
[0034] Then, a proper amount of the liquid green body or the semi-solid green body to be formed is placed in the extrusion casting mold 2, and the Figure 5 , Figure 6 and Figure 7As shown, a dustproof mechanism 11 is provided on both sides of the extrusion casting mold 2, and the dustproof mechanism 11 includes a dust cover 12 fitted on the upper end of the extrusion casting mold 2, a connecting plate 13 fixedly connected to the middle of the dust cover 12, an auxiliary plate 14 for support, and auxiliary blocks 15 fixedly connected to the front and rear sides of the lower end of the connecting plate 13. By pulling the pull rod 19 upward, the pull rod 19 and the connecting plate 13 are connected by a slot, the pull rod 19 slides with the connecting plate 13, and the pull rod 19 is fixedly connected to the positioning plate 17. The positioning plate 17 is driven to move at the lower end of the connecting plate 13, and the positioning plate 17 squeezes the spring 16, so that the spring 16 is elastically deformed, and the positioning plate 17 is separated from the protrusion 18, thereby releasing the limit between the auxiliary plate 14 and the connecting plate 13, and then the connecting plate 13 is pulled toward the side close to the extrusion casting mold 2, and the connecting plate 13 and the auxiliary plate 14 slide.

At this time, the spring 16 restores its elastic deformation, drives the positioning plate 17 to move downward and engages with the protrusion 18 at the upper end of the auxiliary plate 14 close to the base 1, so as to facilitate the fixing between the connecting plate 13 and the auxiliary plate 14. The dust cover 12 is arranged on the outer side of the upper end of the extrusion casting mold 2, which can play a good dust protection role and prevent external device dust from entering the extrusion casting mold 2 and affecting the processing quality of the product. Then, the electric telescopic rod 7 installed at the upper end of the fixed bracket 6 is started, and the output end of the electric telescopic rod 7 is fixedly connected with a movable push plate 8.
