Embodiment 1

[0021] as attached figure 1 And attached figure 2 As shown, a cleanable injection mold includes an upper mold and a lower mold. The upper mold is a punch 1, and the lower mold is a die 2. When the punch 1 and the die 2 are engaged, the gap between the punch 1 and the die 2 is A molding cavity is formed between them, and the punch 1 is provided with an injection channel communicating with the molding cavity. Use the injection molding machine to inject plastic melt into the molding cavity through the injection channel.

[0022] The bottom of the die 2 is provided with a cooling chamber, the cooling chamber is provided with a slide plate 6 slidingly connected with the die 2, the slide plate 6 can slide vertically on the die 2 and the slide plate 6 closes the cooling chamber, the slide plate 6 and the die 2 A seal is provided at the sliding connection to seal the cooling chamber. The bottom of the slide plate 6 is provided with a clip spring 5 with one end fixed on the slide p...

Abstract

The invention relates to the technical field of mold machining, and discloses a cleanable injection mold. The cleanable injection mold comprises an upper mold and a lower mold; the upper mold is a convex mold; the lower mold is a concave mold; when the convex mold is clamped with the concave mold, a molding cavity is formed between the convex mold and the concave mold; the convex mold is providedwith an injection molding way communicating with the molding cavity; a cooling cavity is formed in the bottom of the concave mold, and is provided with a slide plate; a pressure spring is arranged atthe bottom of the slide plate; one-way valves are arranged on two sides of the cooling cavity; air cavities communicating with the external are arranged on two sides of the cooling cavity; rotating shafts are arranged in the air cavities; spiral blades are fixed on the rotating shafts; the convex mold is provided with a cooling way and a collecting cavity; a pressing plate is arranged in the collecting cavity; a pushing rod slidingly connected with the convex mold is fixed on the pressing plate; an air way and a closing block are arranged on the side wall of the molding cavity; the closing block is provided with a connecting rod; and the connecting rod is connected with the rotating shafts through one-way clutches. The cleanable injection mold is simple in structure, can remove dust of themolding cavity, scrapes off impurities in the molding cavity, and meanwhile, can cool plastic melts.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a cleanable injection mold. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products are usually injection molded with rubber or plastic. Injection molding can also be divided into injection molding molding method and die casting method. [0003] The vast majority of auto parts are molded by injection molding. Generally, injection molding machines, namely injection machines and injection molding machines, are used. Injection molding machines make thermoplastic or thermosetting plastics into various shapes of plastic auto parts using plastic molding molds. , so the injection molding of auto parts is achieved through injection molding machines and injection molds. [0004] The existing injection mold includes a die and a lower die. The die is a die and the die is a punch. When the die and the die are engaged, a clo...
