However, the guide rods between the upper and lower molds of the mold are separated, and the upper and lower molds cannot be used smoothly and accurately during use, which easily affects the molding effect of the mold.

Utility model content

The technical problem solved by the utility model is to provide an automobile lamp mold, which can make the upper and lower mold bases work together smoothly and accurately.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

An automobile lamp mould comprises a base and a lower die seat placed on the base, the lower die seat is provided with a groove-shaped molding cavity, a convex punch is arranged in the molding cavity, and an upper die seat is arranged above the punch, The upper die base includes a concave die that matches the shape of the punch and can be embedded in the cavity of the casting, bosses that protrude on both sides of the top of the die, and an injection channel that penetrates the die up and down. A cylinder is installed, the piston rod of the cylinder is set upward, the upper end of the piston rod is fixed with a connecting block, and the connecting block is fixedly connected with the top of the die at the same time, and two guide rods are fixed on the base, and the guide rods penetrate upward through the side wall of the lower mold base, Bosses and connection blocks.

As a further improvement of the above technical solution:

The material injection channel is composed of an upside-down truncated upper channel and a lower channel connected up and down, and the inclination of the inner wall of the upper channel is smaller than the inclination of the inner wall of the lower channel. Further, the diameter of the upper end of the upper channel is 3 to 5 times the diameter of the lower end; the diameter of the upper end of the lower channel is 2 to 1.5 times the diameter of the lower end. The constriction degree of the upper channel is smaller than that of the lower channel, so that a large flow of molding raw materials can be accommodated in the upper channel, and then quickly flow into the molding cavity in the lower channel.

A paint layer is smeared on the punch.

A surrounding frame is arranged around the side wall of the molding cavity of the lower mold base.

Compared with the prior art, the advantages of the present utility model are:

There are two through guide rods and piston rods of two cylinders between the upper and lower mold bases of the automobile lamp mold. The upper mold base can move smoothly in the vertical direction under the action of the cylinder, so that it can be accurately matched with the lower mold base. .
