Embodiment Construction

[0031] First inject the middle layer (serial number 1), then inject the lower side (sequence number 3) of the outer periphery of the middle layer, and finally inject the upper side (serial number 2) of the outer periphery of the middle layer; a fixed mold and a movable mold are set to realize injection molding (see figure 2 );

[0032] The specific steps are:

[0033] (1) No. 1 fixed mold and No. 1 moving mold are injected into the middle layer;

[0034] (2) The middle layer stays on the No. 1 movable mold side, rotates 90 degrees, and closes the mold;

[0035] (3) No. 1 fixed mold and No. 2 dynamic mold inject the middle layer; the middle layer of the mold opening is left on the side of the No. 2 moving mold; the No. 3 fixed mold and the No. 1 moving mold are used as cooling chambers; the middle layer of the mold opening is left on the No. 3 side Fixed mold side; reverse rotation 90 degrees;

[0036] (4) No. 1 fixed mold and No. 1 dynamic mold inject the middle layer; the...

Abstract

The invention discloses an implementation method for three-layer four-station injection molding of a thick-wall part. According to the sequence of injection molding, injection molding is conducted on a middle layer at first, then, injection molding is conducted on the upper side of the periphery of the middle layer, and finally, the lower side of the periphery of the middle layer is subjected to injection molding; injection molding is implemented by arranging fixed molds and movable molds; and the fixed molds are uniformly arranged at four stations and are perpendicular to one another, and the movable molds are uniformly arranged at four stations and are perpendicular to one another. According to the implementation method, the movable molds and the fixed molds of the product exchange and stay through repeated rotating, the injection mold period is shortened, and the part precision is improved.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a scheme for realizing layering of a thick-walled light guide for molds.. Background technique [0002] Light guides are an important part of automotive lighting. In recent years, more and more automobile lights use light guides as inner light distribution mirrors. Using light guides as inner light distribution mirrors can not only reduce the cost of lights, but also reduce energy consumption while ensuring the same function. In addition, The style of the headlights is also beautiful because of the use of light guide strips. [0003] As a kind of light guide, the thick-walled light guide is a structural member that guides the light emitted by the light-emitting diode from the circuit board to the light-emitting position. This structural member is generally made of PC (polycarbonate) material, or PMMA (polymethyl Methyl acrylate) material. [0004] Due to the long coolin...
