Integrated lifting ring bottle blank forming mold

Abstract

The invention belongs to the technical field of injection molds, and particularly relates to an integrated lifting ring bottle blank forming mold which comprises a front mold frame and a rear mold frame. The front mold frame is sequentially provided with an injection plate, first forming plates and second forming plates. First cavities are formed in the side ends, close to each other, of the two first forming plates, and lifting ring forming cavities are formed between the first cavities and the injection plate during mold closing. The injection plate is provided with an injection port communicating with the lifting ring forming cavities. The second forming plates are provided with second forming cavities, and the second cavities communicate with the first cavities. The rear mold frame isprovided with two third forming plates. Third cavity pieces are arranged on the two third forming plates. A third cavity is formed between the two third cavity pieces when the two third cavity piecesare close to each other, and a mold core is arranged in the third cavity. The second cavities are provided with third conical grooves. Third conical parts are arranged at the same ends of the two third cavity pieces. The two third cavity pieces are close to each other during mold closing, the two third conical parts are contained in the third conical grooves in a matched mode, and a bottle blank body forming cavity is formed among the second cavities, the third cavity and the mold core.

Description

technical field [0001] The invention belongs to the technical field of injection molds, and in particular relates to an integral hanging ring bottle blank forming mold. Background technique [0002] Plastic bottles, etc. are made by bottle blowing machines. During the preparation process, the preform needs to be formed first, and then the preform is blown to form it, and the preform is mainly formed by the preform mold. Hanging ring preforms are often used in infusion bottles, and the bottom of the infusion bottle needs a ring, which is convenient to hang on the fixed hook when in use. [0003] The ring preform includes a preform body, a lifting ring and a sprue column; the preform body is an integral structure and one end is a cylindrical hollow cone structure with an opening; the ring and the closed end of the preform body pass In the connection part, the sprue column is arranged on the suspension ring. [0004] In the existing preform mold, the end of the preform body h...
