Oil tank filler cap double-color injection molding mold

Abstract

The invention relates to an oil tank filler cap double-color injection molding mold. The oil tank filler cap double-color injection molding mold comprises a movable mold plate and a fixed mold plate which are arranged in parallel, and the fixed mold plate is connected with a first mold core, a first mold cavity, a second mold core and a third mold cavity. The movable mold plate is connected with asecond cavity and a fourth cavity. A product primary blank cavity for accommodating a product primary blank is formed when the first mold core, the first mold cavity and the second mold cavity are assembled, and a pouring gate communicating with the product primary blank cavity is formed in the first mold core. A finished product cavity for containing a product is formed when the second mold core, the third mold cavity and the fourth mold cavity are assembled, and pouring gates are formed in the positions, corresponding to a first soft rubber body, a second soft rubber body and a third soft rubber body, of the fourth mold cavity. The oil tank filler cap double-color injection molding mold has the advantages that injection molding of an oil tank filler cap can be completed in one set of mold, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to an injection mold, in particular to a two-color injection molding mold for a refueling mask for a fuel tank. Background technique [0002] The fuel tank refueling mask is an auto part that is installed at the fuel tank refueling port and cooperates with the fuel tank refueling cap to close the fuel tank refueling port. [0003] A newly designed fuel tank refueling mask, refer to Figure 12 , which includes a chassis 101, a main casing 102 connected to one side of the chassis 101, and a secondary casing 103 connected and communicated to one side of the casing, combined Figure 14 and 15 , the projection of the secondary housing 103 is fan-shaped, one end extends from the main housing 102, the other end extends away from the main housing 102, and its inner concave surface faces the chassis 101, and the outer side of the secondary housing 103 is far away from the chassis 101 and the main housing A hollow 104 is provided in the m...

AI Technical Summary

Problems solved by technology

[0004] Using the existing two-color mold technology to carry out injection molding to the above-mentioned newly designed fuel tank refueling mask, it is necessary to use a set of molds to form the main shell 102, the secondary shell 103, the first convex body 106, and the second convex body with hard plastic injection molding. Body 107, the third convex body 108 and the product embryo formed by the fourth convex body 109, then need to manually take out the product embryo and put it into another set of molds and use soft rubber injection molding to form the first soft colloid 111 and the second soft colloid 112 and the third soft colloid 117 to form a finished product; two sets of molds are used for injection molding, and the production cost is high
