Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] Such as Figure 2-10 Shown is the preferred embodiment provided by the present invention.
[0029] It should be noted that, when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0030] It should also be noted that the orientation terms such as left, right, up, and down in this embodiment are only r...

The present invention relates to the technical field of mold equipment, and provides an undercut device, including a coupling block, on which there is an opening groove with a gradually expanding opening, and hooking grooves are respectively extended on the two inner walls of the opening groove along the direction of expanding the opening. , sliding blocks are respectively inserted in the two hook grooves, the sliders are provided with protrusions for fastening with the undercuts, the coupling block is connected with a drive assembly for driving the coupling block to move along the tapered direction of the opening and for limiting the sliding A limit block that moves in the direction of tapering of the opening. The driving part drives the coupling block to move along the direction of opening tapering, and with the coupling block as a reference system, the slider moves in the hook groove along the direction of opening gradual expansion, so that the distance between the two sliders in the hook groove becomes until the protrusion disengages from the undercut. Therefore, the above-mentioned tripping and tripping device has a simple structure and low cost, and the coupling block and the sliding block are detachable and replaceable, and the maintenance is convenient.
Description
technical field [0001] The invention belongs to the technical field of mold equipment, and in particular relates to an undercut device. Background technique [0002] At present, when most factories in the industry produce plastic parts, they usually encounter the situation of 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. [0003] Such as figure 1 As shown, the existing undercut device 20 generally includes an oil cylinder 21, the push rod 22 of the oil cylinder 21 is connected with a slider 23, the oil cylinder 21 pushes the slider 23 through the push rod 22, and the slider 23 pushes the undercut 24 on the product , so that the slider 23 is disengaged from the undercut 24 . The tripping and tripping device 20 of this solution adopts structures such as the oil cylinder 21, which is relatively expensive and unfavorable for subsequent maintenance. Contents of ...
