Molds for the production of airbag covers

Abstract

The invention discloses a mold suitable for the production of a supplementary restraint system cover. The mold comprises an upper mold, a lower mold and a cavity located between the upper mold and the lower mold, wherein the upper mold is sequentially provided with an upper fixed plate, a hot runner manifold and a cavity plate from top to bottom, and a cavity insert is arranged in the cavity plate; and the lower mold is sequentially provided with an oil hydraulic cylinder, a lower fixed plate and a core plate from bottom to top, the lower fixed plate is provided with a cooling water pipe, and the core plate is provided with a core insert, a containing space is formed between the lower fixed plate and the core plate, and the periphery of the containing space is supported through mold legs, and the containing space is internally provided with a support pillar, an ejector pin plate guide pillar, an ejector pin plate, an ejector pin and an ejector rod. The mold has the beneficial effects that after a cavity is moved away, the ejector rod is outwards pushed out by automatic reset elastic force of an elastic part so as to realize the one-time ejection, and meanwhile, a product deforms; the oil hydraulic cylinder is used for driving the ejector pin to be pushed out, so that the product is demolded, the demolding can be realized through two-times ejection, the mold is fast and high-efficiency, and the product does not need to be manually taken.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for producing an airbag cover on an automobile steering wheel. Background technique [0002] In the existing molds for producing airbag covers, demoulding after the master mold is removed requires at least three actions. The number of ejections is large and the operation is complicated, resulting in a larger overall mold size and a greatly increased cost. Cooperating with pick-ups manually reduces production efficiency. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a mold for producing airbag covers that has a simple structure and can be demolded twice. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A mold suitable for producing airbag covers, including: an upper mold, a lower mold and a cavity between them. A female mold core is...
