Abstract

The invention discloses a plastic mold for detecting the water content of molten plastic. By installing a moisture-sensitive sensor module outside the fixed mold part of the plastic mold, the mold can detect the release of water vapor during the melting process of plastic raw materials during use. Concentration, and then through the comparison of parameters can determine the amount of water in the plastic raw materials, which plays a good role in controlling the quality of the mold made; The creative design has greatly improved its sensitivity and response time, produced unexpected technical effects, and has great market application prospects.

Description

technical field [0001] The invention belongs to the field of moulds, and more specifically relates to a plastic mold used for detecting the water content of molten plastics. Background technique [0002] Mold is a tool used to shape objects. It is composed of various parts. It is a general term for various molds and tools used in industry to obtain required products by injection molding, blow molding, extrusion, stamping and other methods. Plastic molds are tools used in the plastic processing industry for the complete configuration and precise dimensions of plastic products, generally including fixed molds and moving molds. [0003] However, the plastic molds in the related art have the following technical problems: during use, the water vapor detection of the molten plastic during the normal working process of the plastic mold is generally not taken seriously. Contents of the invention [0004] Aiming at the problems in the background technology, the present invention p...
