Precision injection mold

Abstract

The invention provides a precision injection mold which comprises a vacuum chamber, a liquid storage chamber and a decision box. The top of the vacuum chamber communicates with the liquid storage chamber through a lower through pipe, a plastic melt is stored in the liquid storage chamber, the bottom of the vacuum chamber is provided with a forming chamber, the bottom of the forming chamber is provided with a semicircular sheet, the bottom of the semicircular sheet makes contact with the top of a guide limiting groove, the bottom of the guide limiting groove is fixedly connected with the uppersurface of a substrate through welding, the left part of the upper surface of the substrate is provided with a repairing chamber, the upper surface and the lower surface of the vacuum chamber are provided with an inflow port and an outflow port correspondingly, the inner rear surface of the vacuum chamber is fixedly provided with a transverse limiting strip and a longitudinal limiting strip through welding, and the upper surface of the transverse limiting strip is in contact with the lower surface of a transverse guide arm. According to the technical scheme, the technical problems in the priorart that the device does not have the capability of absorbing and pumping air inside the device, and automatic cover sealing, excitation acceleration forming, automatic inspection and repair and thelike cannot be achieved are solved, and the application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a precision injection mold. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Plastic injection molding is a method of plastic products. The molten plastic is injected into the mold of the plastic product under pressure, and cooled and formed to obtain various plastic parts. There are mechanical injection molding machines specially designed for injection molding. The most commonly used plastic today is polystyrene. Porosity, shrinkage, underfull mold, burrs, weld lines, silver threads, spray marks, burnt, warping, cracking / rupture, dimension out-of-tolerance and other common injection molding problems description, cause analysis, and in the mold desi...
