Embodiment Construction

[0030] see figure 2 , image 3 with Figure 4 ,in figure 2 It is a schematic sectional view when the slide block of the present invention withdraws from the mold clamping mechanism, image 3 It is a schematic cross-sectional view of the first mold opening of the slide block withdrawal mechanism of the present invention, Figure 4 It is a schematic cross-sectional view of the second mold opening of the slider ejection mechanism of the present invention.

[0031] The sliding block ejection mechanism of the present invention is applied to a two-color mold. The two-color mold includes a first injection master mold, a second injection master mold, two identical male molds, a bunch of blocks 100 and at least one thimble 101. In an embodiment, the slider withdrawal mechanism includes:

[0032] An inlet 102, one end of the inlet 102 is placed in the male mold core 103 of the male mold;

[0033] A base 115, the base 115 is placed in the male template 116 of the male mold, and t...

Abstract

The invention discloses a slide block exiting mechanism. The slide block exiting mechanism comprises an insert core, a base, a first ejector plate, a second ejector plate, a third ejector plate, a striping block, a pull rod, an ejector rod, an elastic element, a positioning ball and a slide block; one end of the slide block is arranged in a male molding board of a male mould; the end, in the male molding board, of the slide block contacts the base; one side of the slide block is correspondingly connected with the insert core, and the other side of the slide block correspondingly contacts a restraining block; a slide groove is arranged in the slide block. According to the slide block exiting mechanism, the slide block, the stripping block, the elastic element and the positioning ball are arranged, so that when a mould is used for injection molding of a first ejecting product, the mould is opened for the first time and the slide block does not exit; and the male mould is rotated by 180 degrees to be matched with a second ejecting female mould for injection molding of a second ejecting product, the mould is opened for the second time and the slide block exits under the acting force of the stripping block. The slide block exiting mechanism enables the first ejecting product to be not scraped when the double-color mould is closed for the second time.

Description

【Technical field】 [0001] The invention relates to a sliding block withdrawing mechanism, in particular to a sliding block withdrawing mechanism applied in a two-color mold. 【Background technique】 [0002] Due to the development of modern technology, single material properties of mobile phone casings or engineering plastic parts can no longer meet the requirements and aesthetic requirements of these products. Two-color molds can use two materials of different colors to meet these design requirements. Two-color molds are two Two kinds of plastic materials are injected on the same injection molding machine, molded in two parts, and the product is only released once. In addition, in the production of plastic products, sometimes undercuts are set on the product. In order to prevent the undercut from leaving the mold core when the mold is opened, a slider ejection mechanism is usually installed in the two-color mold so that the product can be moved smoothly. demoulding.
