Inclined core-pulling plastic mold with rapid cooling structure

Abstract

The invention discloses an inclined core-pulling plastic mold with a rapid cooling structure, and belongs to the field of molds. The inclined core-pulling plastic mold comprises a lower mold and an upper mold, a lower mounting bin is arranged on the lower mold, a plurality of lower mounting columns are arranged in the lower mounting bin, and lower springs are arranged on the lower mounting columns; and a liquid inlet hole is formed in the position, located above the lower mounting bin, of the lower mold, a plurality of folded liquid outlet holes are formed in the positions, located on the two sides of the liquid inlet hole, of the inner part of the lower mold, a plurality of air pressure connecting pipes are arranged at the positions, located at outlets of the folded liquid outlet holes, of the lower mold, and air pressure through holes are formed in the air pressure connecting pipes. According to the inclined core-pulling plastic mold with the rapid cooling structure, the air pressure connecting pipes and other structures are arranged, all the folded liquid outlet holes can be filled with cooling liquid, the cooling area is large, cooling is more uniform and sufficient, cooling liquid is convenient to recycle, heat loss is conveniently prevented through a sliding shielding plate and other structures, and solidification and blockage of an injection outlet are avoided.

Description

technical field [0001] The invention relates to the field of molds, in particular to an oblique core-pulling plastic mold with a rapid cooling structure. Background technique [0002] Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low foaming molding.

[0002] Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low foaming molding. The coordinated change of mold convex, concave mold and auxiliary molding system can process different shapes and sizes. A series of plastic parts, plastic mold is the mother of industry, and the release of new products will involve plastic. The scope of application is also expanding, such as: household appliances, instruments, construction equipment, automobile industry, daily hardware and many other fields. The proportion of plastic products is increasing rapidly, and a well-designed plastic part can often replace multiple parts. The trend of plasticization of traditional metal parts, industrial products and daily products continues to rise. In plastic molds with oblique core pulling, the upper and lower molds are mainly placed on the side. When the injected plastic solution enters the molding chamber, it needs to be adjusted. The cooling of plastic products is mainly carried out through cooling holes and cooling liquid. In order to make the cooling effect better, multiple connected cooling holes are often used to expand the cooling area. However, because the air pressure in the cooling holes is not connected to the outside, the filling The coolant often cannot completely fill each cooling hole, resulting in a much smaller cooling area than expected, uneven cooling, and poor cooling effect. After the mold is withdrawn, since the injection hole is in an open space and communicates with the external airflow, it is easy to Cooling blockage occurs, and workers are often required to manually scrape off the cooling solids and dredge the injection pipes, which is very inconvenient
