Multi-mold forming combined mold multi-flow-channel injection molding system

Abstract

The invention relates to a multi-mold forming combined mold multi-flow-channel injection molding system. The multi-mold forming combined mold multi-flow-channel injection molding system comprises an upper mold assembly and a lower mold assembly, wherein the upper mold assembly and the lower mold assembly can be buckled in a face-to-face mode. Two upper molds which are arranged transversely and symmetrically are fixedly installed in the middle of an upper mold plate in an embedded mode, and are of a rectangular cube structure. Eight pouring channels which are communicated with lower molds are formed in the upper end of each upper mold at intervals in an evenly distributed mode, upper model grooves are formed in the lower ends, corresponding to the lower ends of the upper molds, of the pouring channels, and a flow slowing bay is arranged in the center of every four adjacent pouring channels on the two sides in a symmetrical mode. Injection molding flow channels are formed in the upper ends of the upper molds, and the flow at the output ends of the injection molding flow channels symmetrically arrives at the flow slowing bays in the middle of the two sides in a flow division mode, and then symmetrically arrives at every four adjacent pouring channels from the flow slowing bays through the corresponding injection molding flow channels. A communicated overflowing flow channel is formed in the end, on the outer side of each pouring channel, of the upper mold plate, and flow division separating pieces are arranged between the overflowing flow channels and the flow channels. The mode of synchronous injection molding of a plurality of mold cavities is adopted by the molds, a plurality of products are formed at one time, and the processing efficiency is high; and the quantity of raw materials lost in the flow channels is small, the raw materials are saved, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the field of precision processing of plastic accessories, in particular to a multi-mode molding combined mold multi-channel injection molding system. Background technique [0002] The processing accuracy requirements of auto parts are very high, especially for seals that play a sealing role and have irregular shapes. Multiple contact surfaces play the role of sealing surfaces. Only one time processing can meet the requirements, the efficiency is low, and the effect of mold opening and demoulding is not good, and even damage the workpiece; the production efficiency of separate processing is low, and it causes more waste of raw materials in the runner. The existing ordinary processing molds are difficult to meet the production requirements. quality and efficiency. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a multi-molding combination mol...
