Embodiment Construction
[0053] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The following is attached Figure 1-8 The present invention is described in detail.
[0054] An injection mold with a forced demoulding structure described in this embodiment includes a fixed template 1, a push plate 2, a movable template 3, a supporting plate 4 and a pusher bottom plate 5 arranged in sequence, and the push plate 2 is provided with There is a slider 6, and the slider 6 is slidably connected with the push plate 2;
[0055] The fixed template 1 is provided with an inclined guide column 7 for sliding the sliding block 6; the fixed template is also provided with a locking block 8, and the locking block 8 is installed on one side of the slider 6 ;
[0056] A molding cavity 9 for...

The invention relates to the technical field of dies, and particularly relates to an injection mould with a forced demoulding structure. Compared with the prior art, according to the forced demoulding structure of the mould disclosed by the invention, primary mould opening is carried out between a supporting plate and a movable die plate, a movable core is gradually separated from a plastic part product, and then a space for inward elastic deformation during forced demoulding is provided for a second reverse fastener; further, a push plate is oppositely separated from a fixed die plate, the push plate is opened from the fixed die plate, and a slide block carries out side core-pulling on the plastic part product; after the side core-pulling is concluded, a push element bottom plate is pushed, then the push plate is pushed to leave the movable die plate and carry out opposite movement, at this moment, the push plate is opened from the movable die plate, a movable die core is separated from the plastic part product, the movable die is separated from the plastic part product, and then a space for inward elastic deformation during the forced demoulding is provided for a first reverse fastener; and meanwhile, the plastic part product is ejected to complete the forced demoulding for the plastic part product due to the movement of a movable die insert on the push plate with the push plate.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to an injection mold with a forced demoulding structure. Background technique [0002] see figure 1 and figure 2 , figure 1 is a structural diagram of a product, figure 2 for figure 1 The cross-sectional schematic diagram of the product in ; the product plastic part 10 has a second undercut 12 in the middle, and the first undercut 11 is provided on both sides of the product plastic part 10; due to the use of traditional mold structures, it is impossible to achieve the molded product plastic part The first undercut 11 and the second undercut 12 in 10 are separated from the mold by forced demoulding. [0003] In view of this, it is necessary to develop a forced demoulding mechanism to solve the problem that the above-mentioned hook is relatively large and difficult to directly forcibly demould. Contents of the invention [0004] Aiming at the problems of the prior art, the inv...
