Door seal die for washing machine

Abstract

A door seal die for a washing machine comprises an injection piece die cavity composed of an upper die body, a first upper die core, a second upper die core, a lower die body, a lower die core, a middle die body and a middle core. The middle core is arranged between the upper die body and the lower die body. The first upper die core and the second upper die core are arranged on the upper die body. The lower die core is arranged on the lower die body. The middle core is connected with the upper die body through a pull rod. An upper Haff module is arranged on the middle die body. A lower Haff module is arranged under the middle die body. Compression springs are arranged in an upper sliding block, a lower sliding block and the middle die body and used for moving the sliding blocks outwards for opening. An injection nozzle is formed in the upper die body, and glue injection is conducted from the lower end of the die, so that the situation that an injected glue material carrying impurities in a runner is stored in a sealing lip can be prevented effectively, the defects of the impurities and air clog which are likely to happen to the sealing lip at the glue injection end of the upper end glue injection process are overcome, and the quality of the sealing lip of the key portion of a product is guaranteed; and guide pins are arranged on the upper die body and the lower die body correspondingly, the Haff sliding blocks are guided to be opened and closed, the friction force is small, thorns are not likely to be generated, the mechanical operation reliability is high, the die combination precision can be kept for a long time, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of washing machine molds, and relates to a washing machine door seal mold. Background technique [0002] The existing mold has the following disadvantages: [0003] 1. The existing structure cannot solve the demoulding problem in this case; [0004] Two, the Huff slider spring in the existing washing machine door seal mold is set as an external structure, which has the problem of being easy to loosen and pop up and hurt people, and the spring is just facing the hidden danger of puncturing and scratching the operator. [0005] 3. In the existing structure, the upper and lower half sliders are directly in contact with the template cone surface to overcome the spring force and close together. At the initial stage of closing, the slider is in contact with the upper and lower mold cone surface lines and finally contacts, resulting in rapid wear of the upper and lower mold cone surface line contact points.
