Mold for producing automobile glass switch button and mold opening method of mold

Abstract

The invention discloses a mold for producing an automobile glass switch button. The mold comprises a male mold, a female mold, an upper mold core, a lower mold core, an ejection rod and a product, wherein the top of the ejection rod is provided with a lug and a groove; the shapes of the lug and the groove are matched with the shapes of an inverted buckle and a snap joint groove; the middle of the ejection rod is provided with two oblique surfaces: a first oblique surface and a second oblique surface which are respectively positioned on the symmetrical surfaces of the ejection rod; the middle outer periphery of the ejection rod is provided with a positioning edge. The invention also discloses a mold opening method of the mold for producing the automobile glass switch button; the lug of the ejection rod is smoothly separated from the inverted buckle of the product by utilizing the acting force and counter-acting force between the two oblique surfaces and the positioning edge of the ejection rod. By the mode, the automobile glass switch button can be produced well, and mold can be opened smoothly, so that the product quality and the productivity are enhanced.

Description

technical field [0001] The invention relates to the field of molds, in particular to a mold for producing automobile glass switch keys and a mold opening method thereof. Background technique [0002] Plastics are widely used in the automotive field due to their superior performance. They have the advantages of simple processing, easy assembly, light weight, good corrosion resistance, long life, and low cost. Part of the plastic material can also be recycled, saving resources. Injection molding is the most important technology in the production of automotive plastic parts. Most plastic parts, such as fan blades, mirror covers, various switch buttons, etc., are manufactured by injection molding. [0003] like image 3 As shown, it is a kind of automobile glass switch button key, which mainly includes: an insertion rod and a top cover. The top cover is located on the top of the insertion rod. There is an undercut with a thinner thickness between the insertion rods, and a ...
