Dual-color injection mold of molded liquid shampoo bottle cap product

Abstract

The invention discloses the technical field of dual-color injection molds, and particularly discloses a dual-color injection mold of a molded liquid shampoo bottle cap product. The dual-color injection mold comprises a top plate, a hot runner plate, a fixed mold plate, a movable mold plate, a bearing plate, a square iron, an ejector retainer plate, an ejector base plate and a bottom plate; a fixed mold is arranged on the fixed mold plate, a movable mold is arranged on the movable mold plate, an ejector pin and a sleeve are arranged at the upper end of the ejector retainer plate, the body further comprises a shifting rod, a fixed plate and a hydraulic oil cylinder, and the top plate, the hot runner plate, the fixed mold plate, the movable mold plate, the bearing plate, the square iron, the ejector retainer plate, the ejector base plate and the bottom plate are sequentially arranged from top to bottom, when mold opening is carried out, the fixed mold and the movable mold are separated, the ejector pin is used two times, and ejects the product from the movable mold together, a hydraulic oil cylinder drives the shifting rod to carry out cover closing on the product and drives the shifting rod to be subject to resetting and returning, the ejector pin ejects the product subject to cover closing, then, the fixed mold and the movable mold are assembled, the rejection rate and the production cost can be reduced, and the stability can be improved.

Description

technical field [0001] The invention discloses the technical field of two-color injection molds, and more specifically discloses a two-color injection mold for forming shampoo bottle cap products. Background technique [0002] With the development of the economy and the prosperity of the market, the types of pre-packaged food are becoming more and more abundant. Leakage and breakage will occur. For traditional lid products, the common production method is to add a process to manually close the lid after the mold is formed. Because of the addition of a process, the production cost of the enterprise is increased, because manual contact is required for assembly. The cover will inevitably bring dust into the product that needs to be closed, which will affect the precision and stability of the product and lead to an increase in the scrap rate of the product. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a kind of two-col...
