Abstract

The mold unit includes one upper mold with one first through hole, one lower mold with one second through hole, and one locating set with one first embedded block and one second embedded block for being held into the first through hole and second through hole separately. The first embedded block has one locating pin in one end and the second embedded block has one locating hole in one end opposite to and fitting to the locating pin. The first embedded block has outer thread and the first through hole has inner thread to match the outer thread for the locating pin and the locating hole to match tightly.

Description

【Technical field】 [0001] The invention relates to a plastic injection mold device, in particular to a mold device which realizes precise positioning by adjusting the expansion and contraction of positioning pins. 【Background technique】 [0002] At present, in products such as electronics, automobiles, motors, electrical appliances, instruments and meters, home appliances and communications, 70% to 90% of parts are manufactured by mold forming, and molds have become an important equipment for industrial production. Moreover, most of the plastic products are made by injection molding devices. [0003] The mold device disclosed in the prior art includes an upper module and a lower module, and when using this kind of mold for molding, especially during the mold closing process, the precise positioning of the upper module and the lower module is very important. Usually, when the mold is closed, the positioning pin and the positioning hole matching the positioning pin are used fo...
