A mold device for the production of large buttons

Abstract

The invention discloses a die apparatus used for producing a large button, which comprises a front die and a rear die. The die apparatus used for producing the large button is characterized in that a hot runner system capable of injecting plastic cement at a fusion state to the inner part of a cavity of the front die is arranged at the upper part of the front die, a line is arranged on the rear die at one side of the cavity of the front die, a shovel base is provide at the outer side of the line, the shovel base is connected to the rear die through a mold insert and a compact block, a slide block mold insert used for positioning a large button nozzle of a spray valve is connected on the line, a push pedal mold insert cooperated with the cavity of the front die is arranged on the rear die, a locator pin used for positioning a channel in the large button of the spray valve is arranged on the push pedal mold insert, and a material drawing rod is arranged between the front die and the rear die. A purpose of the die apparatus used for producing the large button aims to overcome the disadvantages in the prior art, the die apparatus has simple structure, and can effectively avoid the wearing due to bounce of the front die to a heat nozzle.

Description

technical field [0001] The invention relates to a mold device for the production of large buttons. Background technique [0002] The existing mold device for big button production generally uses the front mold to spring open to drive the shovel base to open the row position, and the front mold and the rear mold are separated and the push plate pushes out the product. However, the existing design is It is easy to wear and tear the hot nozzle during the molding process, and the existing front mold pop-up structure has poor stability and is not conducive to production. [0003] Therefore, the existing mold device for large button production needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a mold device for the production of large buttons, which has a simple structure and can effectively avoid the wear of the hot nozzle caused by the ejection of the front mold. ...
