Problems solved by technology

Its shortcoming is that this solution is easy to produce clamping lines on the outer surface of the bumper, which affects the appearance, and if the undercut of the product contains deep ribs, it is easy to stick to the inclined roof and affect the demoulding problem

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] like figure 1 , figure 2 As shown, an injection mold inclined ejector pin linkage mechanism includes:

[0029] Inclined roof 1, one side of the inclined roof 1 is inclined and slidably arranged on the core, and an injection cavity is formed between the other side of the inclined roof 1 and the cavity. The entire inclined roof 1 has a plate-like structure, such as figure 1 As shown, the inclined top 1 moves to the right while moving along the mold opening direction (upward). Since the product 6 in the figure has an undercut structure on the left side, the first step of undercutting is realized. like figure 2 , image 3 As shown, the inclined top 1 is lateral to the chute 11, and the spring pin 2 is slid in the chute 11, and the top of the spring pin 2 is set corresponding to the undercut structure on the side of the product 6. The ...

Abstract

The invention discloses an injection mold pitched roof and vibrating needle linkage mechanism and an inverted buckle removing method. The injection mold pitched roof and vibrating needle linkage mechanism comprises a pitched roof, a pitched roof rod arranged on the pitched roof, a vibrating needle and a transmission mechanism, the vibrating needle is elastically connected with the pitched roof and is slidably arranged in the pitched roof, the pitched roof rod is rotationally arranged on the pitched roof, and the pitched roof rod drives the vibrating needle to stretch on the pitched roof through the transmission mechanism. The injection mold pitched roof and vibrating needle linkage mechanism has the following beneficial effects that (1), the reverse buckle removal in the cavity direction is realized by arranging the pitched roof, and an external parting mold does not need to be arranged on the cavity, so that the exposure of a clamping wire is avoided, and the appearance consistency is ensured; (2), by arranging the vibrating needle, a product is locked and driven when the first section is opened, and the inverted buckle is efficiently removed when the second section is opened; (3), two-section demolding and reverse buckle removal are realized through two moving modes of an inclined ejector rod structure; and (4), the mold is simple in structure and simple and convenient to use and operate.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an injection mold inclined ejector pin linkage mechanism and an undercut method. Background technique [0002] When a large number of plastic parts are ejected from the mold, they usually encounter the situation of falling off and buckling. The undercut is a structural part of the product that has a "reverse covering" mold, so that the product cannot be demolded directly in one direction. Some plastic parts are equipped with many flanges and undercuts due to the need for assembly. The undercut structures are respectively arranged on the front and side of the product. Therefore, the corresponding mold is usually equipped with multiple undercut structures corresponding to different undercut directions. The commonly used mold structure is the outer parting type, usually with a large straight top and a slanted top, and a slider to make the product out of the undercut. The disadvanta...
