A two-color injection molding mold for fuel tank refueling mask

Abstract

The invention relates to a two-color injection molding mold for a fuel tank refueling mask, which comprises a movable platen and a fixed platen arranged in parallel, and the fixed platen is connected with a first core, a first cavity, a second core and a third cavity; The movable template is connected with a second cavity and a fourth cavity; when the first core, the first cavity and the second cavity are closed, a product preliminary cavity for accommodating the product preliminary embryo is formed, and the first mold cavity is A core is provided with a gate that communicates with the initial embryo cavity of the product; the second core, the third cavity and the fourth cavity form a finished cavity for accommodating the product when the second core, the third cavity and the fourth cavity are closed, and the fourth cavity corresponds to the first cavity. The positions of the first soft gel, the second soft gel and the third soft gel are all provided with gates. The advantages of the invention are that the injection molding of the fuel tank refueling mask can be completed in a set of molds, which greatly reduces the production cost.

Description

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

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
