Abstract

The invention discloses an injection mold for making a helical fan, comprising a movable mold base plate, square iron, a supporting plate, a movable mold plate, a fixed mold plate, a front inner mold, a helical mold core, a split type inclined bearing, a slide block, a scraping machine, an inclined guide pillar, a water gap push plate, a fixed mold base plate, a positioning ring, a bottom needle plate, a surface needle plate, an ejector sleeve and an ejector sleeve needle. According to the invention, the structure is simple, the cost is reduced, the structure comprises the slide block and the helical mold core, the helical mold core allows the ejector sleeve to extrude a mold product by rotating the split type inclined bearing, thus the complicated demolding problem becomes simple, and the quality of the product is guaranteed.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for making a spiral fan. Background technique [0002] The plastic part of the spiral fan is a part with helical curved blades in the whole circle. The structure of the part is complicated and it is not easy to demold. At present, although there are related molds in the enterprise for production injection molding, the structure is very complicated, the production cost is high, and the dimensional accuracy It is also difficult to control, thereby affecting the mechanical strength of the product and easily causing product quality defects. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide an injection mold for making a spiral fan, so as to overcome the defects of complex structure, high production cost and difficult quality assurance in the injection mold in the prior art....
