Abstract

The invention provides injection molding equipment with a hot nozzle twice ejection-free structure hot nozzle die. The hot nozzle twice ejection-free structure hot nozzle die comprises a die channel component, a die fixed die component, a die movable die component and a die sliding block exiting mechanism. The hot nozzle twice ejection-free structure hot nozzle die adopts four holes in one die anda hot channel adhesive dispensing manner, is parted and opened twice to realize automatic injection molding production of a product, is simple in structure, and can reliably realize core-pulling demoulding of the front die side face of the product and leaves the product on a rear die; as the die adopts the ejection-free structure to simply and efficiently demould, the production and manufacturingcost of the die is reduced, and the production and manufacturing period of the die is shortened; and as the hot channel is used, generation of degraded material is effectively reduced, the injectionmolding quality is improved and the production period of the injection molding product is shortened.

Description

technical field [0001] The invention relates to the field of mechanism design of injection molds, in particular to injection molding equipment with hot nozzle double-extrusion structure hot nozzle molds. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and melted plastic into a mold cavity under high pressure from an injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] The appearance of the product needs to be core-pulled and demolded from the side of the rear mold. Therefore, the appearance of the product is high, and there should be no obvious traces during production. The mold structure is compact, and it is difficult to realize fully automated producti...
