Problems solved by technology

[0002] In the design of two-color molds, some products with high requirements, the appearance or functional requirements make it difficult to enter the glue, and the traditional glue injection method will make the appearance of the product flawed or bad
[0003] see figure 1 and figure 2 As shown, the product 100 is a product formed by a two-color mold. The appearance of the product 100 includes hard rubber 110 and soft rubber 120 on the inside and outside of the hard rubber 110, and the soft rubber 120 on the inside of the hard rubber 110 not only has appearance requirements but also There are functional requirements; the appearance surface of the product 100 must not have flaws, so the appearance area cannot be glued; moreover, the inner frame area of ​​the product 100 is small, and the ribs on the side wall are locally high, so latent glue injection cannot be used; therefore, according to the traditional The glue feeding method cannot meet the requirements of the product 100

Abstract

The invention discloses a bi-color mold lapping and gluing mechanism which is applied to bi-color molds. The bi-color mold lapping and gluing mechanism comprises a base, a support plate, an ejector pin and an insert core, wherein the base is arranged in male mold cores of male molds, and is provided with a groove; the support plate is rotatably arranged in the groove of the base; the ejector pin is arranged on the support plate; the insert core is arranged on the support plate; elastic elements are arranged between the insert core and the male mold cores. According to the bi-color mold lapping and gluing mechanism provided by the invention, the inner-side lapping and gluing of products can be realized when produced products cannot be subjected to glue feeding from outer surfaces and inner sides in a concealed mode, so that outer surfaces of products are flawless.

Description

【Technical field】 [0001] The invention relates to a glue feeding mechanism, in particular to an overlapping glue feeding mechanism used in a two-color mold. 【Background technique】 [0002] In the design of two-color molds, some products with high requirements, the appearance or functional requirements make it difficult to enter the glue, and the traditional glue injection method will make the appearance of the product flawed or bad. [0003] see figure 1 and figure 2 As shown, the product 100 is a product formed by a two-color mold. The appearance of the product 100 includes hard rubber 110 and soft rubber 120 on the inside and outside of the hard rubber 110, and the soft rubber 120 on the inside of the hard rubber 110 not only has appearance requirements but also There are functional requirements; the appearance surface of the product 100 must not have flaws, so the appearance area cannot be glued; moreover, the inner frame area of ​​the product 100 is small, and the rib...
