Referring to fig. 1-8, according to an aspect of the present invention, the present invention provides a demolding assembly, comprising:

the top block 1 is internally provided with an accommodating groove 2, and a clamping part is formed on the side wall in the accommodating groove 2;

the fixed insert 3 and the sliding block 4 are arranged in the accommodating groove 2, and the fixed insert 3 is in sliding fit with the sliding block 4;

slider 4 still is formed with the joint position, joint position and joint portion joint to when making kicking block 1 remove, slider 4 can slide along fixed mold insert 3 and along with kicking block 1 together removes.

In the above embodiment, be provided with holding tank 2 in kicking block 1, fixed mold insert 3 and slider 4 set up in holding tank 2, and fixed mold insert 3 makes slider 4 can slide for fixed mold insert 3 with slider 4 sliding fit. Through set up joint portion in holding tank 2, set up the joint position on slider 4, can be so that joint position and joint portion joint cooperation and then make slider 4 can be along with kicking block 1 together motion. In summary, when the top block 1 moves, the slide block 4 can slide relative to the fixed insert 3 and move together with the top block 1, so that the slide block 4 is separated, and the demolding process is completed.

It should be noted that, in the prior art, the top block 1 may be mounted on the housing 9 of the product, for example, a mounting hole is formed on the automobile housing 9, and the top block 1 is slidably mounted in the mounting hole. Be provided with bayonet socket 8 on the slider 4, be provided with the product buckle on the bayonet socket 8, the product buckle can be the working of plastics buckle for be connected with other working of plastics of car. Because the product buckle drawing of patterns space is little, lead to the drawing of patterns inconvenient. Therefore, the ejector block 1 can drive the sliding block 4 to move together to complete the demoulding process. In addition, the sliding block 4 and the top block 1 are arranged in a clamping mode, and the convenience in installation and disassembly is mainly achieved. This embodiment has the convenient, the convenient advantage of the installation of drawing of patterns subassembly and dismantlement of drawing of patterns convenience.

Further, referring to fig. 3, 5-8, the clamping portion is a groove 21, the groove 21 is formed by inward concave portions of the side wall of the receiving groove 2, the clamping portion includes a protruding end 41 engaged with the groove 21, and the protruding end 41 is formed by outward convex portions of the side wall of the slider 4. The recess 21 grips the protruding end 41 to ensure that the slide 4 can move out with the top piece 1 to complete the ejection process. As for the shapes of the groove 21 and the protruding end 41, they can be set according to actual needs as long as the sliding block 4 and the top block 1 can be ensured to be clamped with each other. Such as a semi-circular shape, an oval shape or a square shape, the preferred embodiment is a square shape.

Further, referring to fig. 3, 5-8 again, the number of the grooves 21 is two, the two grooves 21 are disposed oppositely, the number of the protruding ends 41 is also two, and the two protruding ends 41 are disposed on two opposite sides of the slider 4.

The push rod 5 can be used for pushing the ejector block 1 to move, and then the demolding process is smoothly completed. The push rod 5 can be manually pushed or can be connected with an external driving part, and the automatic demoulding process is completed through the driving part. The driving member here may be a driving motor or a driving cylinder.

Further, referring to fig. 1 to 4, the number of the receiving grooves 2 is four, the slider 4 includes a first slider 6 and a first slider 7, the number of the first slider 6 is three, and the number of the first slider 7 is one. The big kicking block 1 can drive four sliders 4 simultaneously and accomplish the drawing of patterns, promotes drawing of patterns efficiency. The structure of the slider 4 may be the same or different, and this is set according to the actual situation. It should be noted that the slider 4 described in the foregoing embodiment has a structure in which both the first slider 6 and the first slider 7 are provided.

According to the utility model discloses an on the other hand, refer to fig. 9, the utility model discloses still provide a demoulding system, demoulding system includes foretell drawing of patterns subassembly, still includes casing 9, and casing 9 is formed with the mounting hole, installs in the mounting hole in kicking block 1 slidable, still is provided with bayonet socket 8 on the slider 4, bayonet socket 8 and casing 9 joint. The bayonet 8 is provided with a product buckle, the shell 9 can be a plastic part of an automobile, and the product buckle is used for being connected with the plastic part of the automobile. Since the demolding system includes all technical solutions of all the above embodiments, at least all the beneficial effects brought by all the above embodiments are achieved, and no further description is given here.

Above only be the utility model discloses an optional embodiment to do not consequently restrict the utility model discloses a patent range, all be in the utility model discloses a technical idea down, utilize the equivalent structure transform of doing of the contents of description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection scope.
