According to a further technical scheme, the back-off demoulding structure is arranged in the mould opening direction of the mould.
According to the technical scheme, the back-off demoulding structure further comprises a limiting screw and a spring, the limiting screw is in partial thread fit with the elastic block and completely sinks into the elastic block, the spring is sleeved on the limiting screw, when the mould is closed, the spring is compressed, and when the mould is opened, the spring automatically pushes out the sliding block by means of the elastic action of the spring, so that unhooking is realized.
According to the technical scheme, the elastic block is provided with an inverted buckle, the inverted buckle is clamped with an inverted buckle groove in the sliding block, and the front die and the sliding block are clamped together.
According to the technical scheme, the reverse buckle is convex, the convex outer contour is matched with the shape of the reverse buckle groove, and clamping is achieved.
The utility model has the advantages that:
use this practical technical scheme, including back-off demoulding structure, in the slider was located to back-off demoulding structure part, when the mould die sinking, back-off demoulding structure relied on self effect auto-eject, realized withdrawing from the back-off. The traditional mode of using an oil cylinder as a power source is replaced, the implementation mode is simple, the injection molding cost and the mold processing time are reduced, and the mold steel cost is reduced.
Description of the drawings:
the accompanying drawings, which form a part of the present application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention and not to limit the invention.
In the drawings:

FIG. 2 is an enlarged view of portion A of FIG. 1;
FIG. 3 is a schematic view of the back-off exit structure of FIG. 1;
fig. 4 is an enlarged view of a portion a-1 of fig. 3.
In the figure: 1 front mould, 2 sliders, 3 elastic blocks, 4 limiting screws, 5 back-off buttons, 6 springs and 7 back-off grooves.
The specific implementation mode is as follows:
the technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, the utility model provides a back-off demoulding structure, including back-off demoulding structure, back-off demoulding structure part is located in slider 2, and when the mould die sinking, back-off demoulding structure relies on self effect auto-eject, realizes withdrawing from the back-off, back-off demoulding structure is including bullet piece 3, and when not unhooking, bullet piece 3 will be in front mould 1 and slider 2 joint together, at this moment 3 partly in front mould 1 of bullet piece, partly in slider 2, when the mould unhook, bullet piece 3 auto-eject slider 2 makes front mould 1 and slider 2 autosegregation. The utility model replaces the traditional mode of using the oil cylinder as a power source, and the realization mode is simple; the traditional mode of using an oil cylinder as a power source is replaced, the implementation mode is simple, the injection molding cost and the mold processing time are reduced, and the mold steel cost is reduced.
In this embodiment, the inverted-buckle demolding structure is arranged in the mold opening direction of the mold. The withdrawing mechanism along the mold opening direction avoids the problems of larger injection molding machine caused by the over-thickness of the mold in the thickness direction and environmental protection caused by hydraulic core pulling caused by using an oil cylinder or a complex mechanism.
