Problems solved by technology
[0006] Purpose of the invention: In order to overcome the above deficiencies, the purpose of the present invention is to provide a preparation process for forming a narrow mouth insert on a blow molded part. The preparation process is simple, and a process ring is used to seal between the core pulling and the insert, thereby It prevents the material blank from breaking under the action of air pressure. After forming, the process ring is cut off by post-processing method, which solves the problem that the existing technology can only form an open insert on the blow molded part but cannot form a narrow opening. Technical problems of inserts, broad application prospects

Embodiment Construction
[0035] The following will be combined with Figure 1~7 and specific embodiments, clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0036] In practical applications, it is often necessary to assemble blow molded parts with other parts. Due to the low manufacturing precision of many blow molded parts, poor surface quality, or low strength, it is difficult to have a better assembly surface when blow molded parts are assembled with other parts, resulting in low assembly quality. In order to solve this problem, it is often used to form an external injection molding insert or hardware insert on the blow molded p...

A preparation process for forming a narrow mouth insert on a blow molded part, comprising forming a narrow mouth injection molding insert on the blow molded part and forming a narrow mouth metal insert on the blow molded part; said forming a narrow mouth insert on the blow molded part Injection molding inserts, including the following steps: mold opening, pouring into the blow molded parts, adding a process ring, blanking, blow molding, cooling, core pulling, demoulding, post-processing; the mold opening is to set the core pulling on the mold device, the mold is composed of a left mold and a right mold, the left mold and the right mold are arranged oppositely, and the mold cavity is between the left mold and the right mold; one end of the core pulling device penetrates the left mold and enters The mold cavity, the core pulling device can move left and right. The preparation process for forming a narrow-mouthed insert on a blow-molded part according to the present invention is simple, and solves the problem that the prior art can only form an open-mouthed insert on a blow-molded part but cannot form a narrow-mouthed insert. Technical problems, broad application prospects.
Description
technical field [0001] The invention belongs to the technical field of blow molding technology, and in particular relates to a preparation process for forming a narrow mouth insert on a blow molding part. Background technique [0002] In the prior art, there are many molding methods, the main molding methods are: injection molding, blow molding, extrusion molding, pressure injection molding, compression molding and solid phase molding. Among them, the blow molding method, also known as the hollow blow molding method, is a method in which the hot-melt parison closed in the mold is inflated to form a hollow product by means of gas pressure. The mold used in the blow molding method is only a concave mold. Compared with injection molding, the cost of the mold is lower, and products with complex undulating curves (shape) can be formed, and the applicability is strong. The blow molded parts are widely used in food, Beverages, cosmetics, pharmaceuticals, daily necessities packagin...
