Combined multifunctional PVC extrusion mold

Abstract

The invention discloses a combined multifunctional PVC extrusion mold. The combined multifunctional PVC extrusion mold comprises an upper mold plate. A lower mold plate is arranged below the upper mold plate. An inner chamber plate main body fixing bolt is arranged at the position of connection between the upper mold plate and the lower mold plate. An upper inner chamber plate and a lower inner chamber plate are arranged below the upper mold plate and are close to the upper part of the lower mold plate. An upper mold plate fine adjustment bolt is arranged on the upper part of the upper mold plate. An inner chamber body split fixing bolt is arranged inside the upper mold plate. Compared with the prior art, the combined multifunctional PVC extrusion mold has the beneficial effects that the design of modularization and transverse layering is adopted for the mold, the mold is divided into an outer mold plate, an inner chamber plate, namely a flow channel mold plate, and a mold orifice plate, and the outer mold plate is subdivided into the upper mold plate and the lower mold plate; and the working procedures including feeding, flow split, extrusion and the like are completed in the inner chamber plate; forming is completed at the mold orifice plate, and the outer mold plate mainly plays a role in supporting, strength enhancement and cooling and heat dissipation; and because the fineadjustment bolt is arranged at the position of connection between the mold orifice plate and the outer mold plate, the interval of the mold orifice plate can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of abrasive tools-plastic extrusion molding dies, and in particular relates to a combined multifunctional PVC extrusion die. Background technique [0002] Abrasives are tools used for grinding, grinding and polishing. Most of the grinding tools are artificial grinding tools made of abrasives and bonding agents, and natural grinding tools are also directly processed into natural ore rocks. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in the processing of non-metallic materials such as grain processing, paper industry, ceramics, glass, stone, plastic, rubber, and wood. Grit size refers to the size of the abrasive particle size. The particle size is divided into two types: abrasive grain and micro powder. For abrasives with a particle size larger than 40 μm, they are called abrasive grains. Classified by sieving method, the p...

Problems solved by technology

The existing technology mainly has the following three disadvantages: 1. Since the template has a certain thickness, when processing the flow channel, it is difficult to feed the knife in some places, and the processing is more difficult
