Problems solved by technology

The existing IMR mold mold glue feeding method generally adopts the middle large oblique pin method, but the middle large oblique pin glue feeding method often causes large oblique pin water leakage, water blockage, ink flushing, etc. during the mold test and production process. It is very inconvenient to use because of many problems

Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] refer to figure 1 and figure 2 , the IMR mold of the present embodiment uses a glue-in structure, which includes a female template and a male template, a mold core 10 and a mold cavity 11 for a shaped product are arranged on the male template, and a fan-shaped inlet is provided on one side of the cavity 11. A rubber plate 20, on which a downwardly inclined curved groove 22 and a glue inlet 21 communicating with the cavity 11 are arranged on the rubber inlet plate 20, and the glue inlet 21 is connected with the cavity 11 through the curved groove 22 connected.

[0016] In the present invention, the width B of the rubber feed plate 20 is 100-140mm, and it is fan-shaped, and the deepest downward depth of the curved groove 22 is 0.5-1.5mm; t...

Abstract

The invention discloses a glue feeding structure for an IMR (In Molding Reprinting) mould, wherein the glue feeding structure comprises a female template and a male template, a mould core and a die cavity used for forming products are arranged on the male template, a glue feeding plate having a fan-shaped structure is arranged on one side of the die cavity, a cambered bent groove inclining downwards and a glue feeding opening communicated with the die cavity are arranged on the glue feeding plate, and the glue feeding opening is communicated with the die cavity though the cambered bent groove. The glue feeding structure disclosed by the invention feeds the glue through the large fan-shaped glue feeding plate on the side edge, and the cambered bent groove is arranged to prevent such problems as water leakage, water path blockage and ink flushing, so that the glue feeding effect is good and the defects of the products caused by pressure can be reduced, and the glue feeding structure is reasonable in structure and simple in operation and can be used for improving the percent of pass of finished products.

Description

technical field [0001] The invention relates to the field of molds, in particular to a glue-feeding structure for an IMR mold. Background technique [0002] IMR technology is the in-mold film technology. It adopts the technology of extending the film with patterns and colors into the mold cavity and forming the plastic integrally while the mold is being formed. These molds all use the mold structure of pouring hot glue channels. Ejection, generally do not make sliders. This technology avoids a series of subsequent processes of plastic molds, such as: scratching, painting, printing, engraving, etc., which greatly shortens the time of mold manufacturing process, and the formed products are beautiful and generous, which are deeply loved by consumers. The existing IMR mold mold glue feeding method generally adopts the middle large oblique pin method, but the middle large oblique pin glue feeding method often causes large oblique pin water leakage, water blockage, ink flushing...
