Injection mold with glue feeding amount manual adjusting device

Abstract

The invention discloses an injection mold with a glue feeding amount manual adjusting device. The injection mold comprises a mold body; a pair of front and back symmetric adjusting flow channel unitsare formed on the surface of the mold body; the adjusting flow channel units are composed of cylindrical groove-shaped central grooves and three diversion channels evenly distributed on the side wallsof the central grooves in circumference; the two diversion channels on the left side of the adjusting flow channel unit on the front side of the mold body communicate with the a first branch channeland a second branch channel; the two diversion channels on the left side of the adjusting flow channel unit on the rear side of the mold body communicate with a third branch channel and a fourth branch channel; flow equalizing adjusting blocks are arranged on the side walls of the central grooves right opposite to the diversion channels on the right sides of the mold body in a sliding mode; rubbermaterial adjusting blocks are arranged on the side walls of the central grooves right opposite to the diversion channels communicating with the second branch flow channel and the third branch flow channel; and the sliding direction of the rubber material adjusting blocks is the same as the direction of the diversion channels right opposite to the rubber material adjusting blocks in the positive direction. According to the injection mold, the amount of rubber material injected into a mold cavity through all diversion channels can be effectively adjusted, so that quality of product forming is guaranteed.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with a manual adjustment device for glue feeding. Background technique [0002] At present, for the injection molds of large plastic products, the gating system of the injection molds often adopts multi-point glue feeding, so as to achieve simultaneous glue feeding everywhere and improve the injection molding efficiency. The runners generally take the main channel to each inlet The shortest distance between the glue points can save materials, but due to the multi-point glue injection, this will make the speed of each glue point inconsistent, which will lead to inconsistent pressure and glue injection in the cavity, which often leads to problems in the injection molding process. The lack of material, burnt and other poor appearance of the product and the ejection problem caused by the excessive tightness of the product due to partial overfilling, so the i...

[0002] At present, for the injection molds of large plastic products, the gating system of the injection molds often adopts multi-point glue feeding, so as to achieve simultaneous glue feeding everywhere and improve the injection molding efficiency. The runners generally take the main channel to each inlet The shortest distance between the glue points can save materials, but due to the multi-point glue injection, this will make the speed of each glue point inconsistent, which will lead to inconsistent pressure and glue injection in the cavity, which often leads to problems in the injection molding process. The lack of material, burnt and other poor appearance of the product and the ejection problem caused by the excessive tightness of the product due to partial overfilling, so the injection speed (that is, the amount of glue) has a great influence on the quality of the product and the efficiency of processing. However, on the current injection mold, the single adjustment of the amount of glue
