Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 , figure 2 As shown in the figure, an injection mold can adjust the tilting top off and undercut mechanism, which is used for the undercut and off of the bumper 7. The front of the end of the bumper 7 is provided with a number of first undercut structures 71, and one side of the end of the bumper 7 is provided with There is a second undercut structure 72, and the undercut mechanism includes:

[0031] The upper doubler plate 61 and the lower doubler plate 51 are connected with the mold cavity 6 below the upper doubler plate 61 , and the mold core 5 is connected with the lower doubler plate 51 . It also includes an adjustable undercut assembly, which is slidably arranged on the core 5, and an injection molding cavity is formed between the adjustable undercut assembly and the cavity 6, and the adjustable undercut assembl...

Abstract

The invention discloses an injection mold adjustable inclined top reverse buckle removing mechanism and a reverse buckle removing method.The reverse buckle removing mechanism comprises a mold core and a mold cavity and further comprises an adjustable reverse buckle removing assembly, the adjustable reverse buckle removing assembly is arranged on the mold core in a sliding mode, and an injection molding cavity with a plurality of reverse buckle structures is formed between the adjustable reverse buckle removing assembly and the mold cavity; and the reverse buckle removing directions of the reverse buckle structures are different, and the adjustable reverse buckle removing assembly moves towards one of the reverse buckle removing directions while moving in the mold opening direction. The clamping wire is prevented from being exposed, and the appearance consistency is guaranteed; the product is locked and driven when the first section is opened, and the inverted buckle is removed when the second section is opened; a two-section mold opening mode is adopted, the first section of mold opening realizes reverse buckle removal of the mold cavity, and the second section of mold opening can simultaneously realize complete opening of the mold cavity and reverse buckle removal of the sliding block, so that the efficiency is improved; the die is simple in structure and easy and convenient to use and operate.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an adjustable slanted top release and undercut mechanism of an injection mold and a method for undercutting. 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 large inclined top, and a slider to make the product o...
