Problems solved by technology

However, the mold is made of metal. When the thermoplastic part is poured into the mold matrix, the male body of the mold exerts pressure on the mold matrix, which is not easy to dissipate heat, and the setting speed of the fan blades is slow.

Abstract

The invention discloses a forming mold for fan blades, which comprises a mold female body and a mold male body matched with the mold female body, wherein injection molding grooves for the fan blades are formed in the mold female body; a cold water flowing channels are formed in the mold female body and below the injection molding grooves for the fan blades, and are positioned at the bottoms of the injection molding grooves for the fan blades; a heating module is arranged in the mold female body; a pull ring is fixed on the mold female body. The forming mold has the advantages that the fan blades subjected to injection molding are high in quality, and the mold has an excellent cooling effect, and can increase the forming rate of the fan blades.

Description

technical field [0001] The invention relates to an injection mold, in particular to a fan blade forming mold. Background technique [0002] Fan blades have complex shapes, uneven wall thickness, high dimensional accuracy requirements, and high surface quality and dimensional stability requirements. Most of the fan blades are made of plastic, which are generally made by injection molding. And injection molding has the following advantages: almost no complexity restrictions, allowing different thermoplastic parts in the mold; no restrictions on the quality of plastic parts; thermoplastics with suitable fluidity within a certain temperature; high-precision plastics can be injected parts, with good surface quality and dimensional stability. With injection molding, it uses a mold. However, the mold is made of metal, and when the thermoplastic part is poured into the mold body, the male body of the mold exerts pressure on the mold body, which is not convenient for heat dissipat...
