Injection mold

Abstract

The invention discloses an injection mold, which includes a back mold core and a front mold core, and also includes monitoring devices. Each monitoring device comprises a metal shell and sensors arranged in the metal shell. The back mold core is provided with grooves for installation of the metal shells. The bottoms of the grooves are provided with thimbles for ejection of the metal shells. When the metal shells are installed into the grooves, the metal shell end faces opposite to the front mold core are flush with the core end face of the back mold core or higher than the core end face of the back mold core. The injection mold can be used for testing new product intra-cavity material molding change and intra-cavity environment change parameters. Through the parameter data analysis, a problem solving method can be found quickly, the mode testing times can be greatly reduced, the new product development cycle can be shortened, and at the same time, the mold development cost can be effectively lowered.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with monitorable material forming change parameters in a mold cavity and environment change parameters in the mold cavity of a new product. Background technique [0002] Plastic products have been widely used in many fields, especially electronic product casings, air conditioner casings, mobile phone casings, automotive interior decorations, etc. The speed of development is amazing, but the requirements for the appearance quality and dimensional accuracy of plastic products are becoming more and more stringent. Its importance is self-evident. [0003] However, the current molding process of the plastic product shell is roughly as follows: the injection molding machine heats the plastic through the barrel, plasticizes, and then injects the molten plastic into the main channel of the mold through the nozzle of the barrel-the mold runner and then enters the...

Problems solved by technology

[0007] The main purpose of the present invention is to provide an injection mold, which aims to solve the problem that the existing mold molding technology cannot observe "complex technical parameter changes in injection molding materials and mold cavities", which affects the analysis of product defects, resulting in too many mold trials The mold cost increases and affects the new product mold opening cycle
