Separated-type double-thread connected micro injection molding test mold

Abstract

The invention discloses a separated-type double-thread connected micro injection molding test mold, belongs to the field of micronano fabrication and injection molding, and relates to a micro injection molding test mold which is a round micro chip that can be mounted and dismounted rapidly and is manufactured by an MEMS technology, and can monitor the pressure and temperature distribution of a cavity in the injection molding process. The test mold consists of a fixed mold component, a moving mold component and a four-claw tool; the fixed mold component consists of a cavity component, a fixed mold frame and a temperature sensor; the moving mold component of the mold consists of a push rod fixing plate, a push rod, a fixed plate, a moving mold frame, a hollow rod and a micro pressure sensor. The test mold is connected by double separated-type threads, has the advantages that sealing is reliable, the mold core is convenient to dismount and replace, the compression fore of the mold core is easy to adjust and the like; pressure and temperature sensors are integrated on a mold, and can monitor the pressure and temperature dynamic variation and distribution in the injection molding process in real time, and have important guidance effect for optimizing the novel technology.

Description

technical field [0001] The invention belongs to the field of micro-nano manufacturing and injection molding, and relates to a micro-injection testing mold that can quickly load and unload a circular micro-core manufactured by a MEMS process and can monitor the pressure and temperature distribution of a cavity during the injection molding process. technical background [0002] Micro-injection molding has the advantages of high molding efficiency, good size and quality consistency, and low cost. It can be used to manufacture various polymer micro-devices, and has market demand in the fields of optoelectronic communication and biomedicine. The micro-injection mold is the core of giving plastic products a complete structure and precise dimensions. The micro-core containing the microstructure is often designed as an independent structure, which is assembled with the mold base through inlays and other methods to form a micro-mold.
