will have a greater impact on cost
[0003] The first color sealing insert of the traditional two-color mold is provided with a sealing rib protruding from its surface. Due to the thin thickness and low strength of the sealing rib, the sealing rib is the easiest to break, which affects the product quality and qualification rate, and affects the quality of the product.

Embodiment

[0014] Such as figure 1 and 2 As shown, a first-color sealant insert structure of a two-color mold includes an insert body 1 and a movable block 2, and the insert body 1 is provided with an installation cavity 11 matching the movable block 2, The movable block 2 is slidably arranged in the installation cavity 11, one end of the movable block 2 is provided with a sealing rib 3, and the other end is provided with an elastic element 4, the elastic element 4 is a spring, and the sealing The rubber ribs 3 protrude from the upper end surface of the insert body 1 .

[0015] Specifically, the size of the upper part of the movable block 2 is smaller than that of the lower part, and a first platform 21 is formed at the junction of the upper part and the lower part, and the upper part and the lower part of the installation cavity match the shape of the movable block 2 respectively. The bottom end of the movable block 2 has a mounting portion, the mounting portion is larger in size to f...

Abstract

The invention belongs to the technical field of double-color molds and provides a first-color sealant insert structure of a double-color mold. The first-color sealant insert structure comprises an insert body and a movable block. A mounting cavity matched with the movable block is formed in the insert body. The movable block is slidably arranged in the mounting cavity. One end of the movable blockis provided with a sealant rib, and the other end of the movable block is provided with an elastic element. The sealant rib protrudes out of the upper end face of the insert body. The first-color sealant insert structure has the beneficial effects that an original sealant rib arranged fixedly is arranged movably; thus, the sealant effect in the mold closing state can be guaranteed, and excessivemold closing force can also be dispersed to the elastic element; the problem that the sealant rib is broken easily is solved; the service life of the mold is prolonged.

Description

technical field [0001] The invention belongs to the technical field of two-color molds, and in particular relates to a first-color sealing glue insert structure of a two-color mold. Background technique [0002] Mold is one of the factors that have a greater impact on the product quality and pass rate of plastic parts in automotive lamps. Among the problem points of product quality and pass rate, mold affects more than 50%. The success of the mold structure design affects the cycle and cost of later maintenance. In order to repair in the shortest time, it is often necessary to work overtime to remove the mold, and the machine tool is fully waiting for processing, which disrupts the overall processing plan of the new mold. will have a greater impact on costs. [0003] The first color sealing insert of the traditional two-color mold is provided with a sealing rib protruding from its surface. Due to the thin thickness and low strength of the sealing rib, the sealing rib is th...
