Description

Technical Field

[0001] The utility model relates to the technical field of foreign body clamps, in particular to a foreign body clamp for a wood-plastic production mould. Background Art

[0002] Wood-plastic production molds are mainly used to cool and extrude heated plasticized wood-plastic raw materials. During the production process, garbage is often stuck in the production molds. Garbage mixed with the wood-plastic raw materials will cause the hardness and strength of the produced products to be unqualified.

[0003] In order to remove the garbage in the production mold, the staff usually use tools such as files and pliers to remove the garbage stuck in the production mold.

[0004] However, some production molds have more complex structures, with crevices, dead corners and other hard-to-reach areas, which make it difficult for files and pliers to reach and effectively clean the molds. Utility Model Content

[0005] To this end, the utility model provides a foreign body clamp for a wood-plastic production mold to solve the technical problem that the prior art cannot clean foreign bodies in the gap of the production mold.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A foreign body clamp for a wood-plastic production mold, comprising symmetrically cross-arranged clamping rods, two clamping rods being hinged at the intersection by a rotating shaft, and gripping portions being provided at the ends of the clamping rods;

[0008] A clamping piece is connected to the end of the clamping rod away from the gripping portion, and the clamping rod drives the clamping pieces to expand outward or retract inward by controlling the opening and closing of the gripping portion;

[0009] The head of the clamping piece is formed into a pointed shape, and a side edge of the clamping piece close to the head is provided with a notch to form a barb.

[0010] Furthermore,

[0011] A plurality of anti-slip stripes are provided on the inner outer wall of the clamping piece, and the anti-slip stripes on the two clamping pieces are staggered with each other.

[0012] Furthermore,

[0013] The thickness of the clamping rod gradually decreases along its length direction;

[0014] Wherein, the thickness of the clamping rod near the end of the clamping piece is consistent with the thickness of the clamping piece.

[0015] Furthermore,

[0016] The two clamping piece heads are gradually bent toward the side with the notch.

[0017] Further,

[0018] The length of the clamping rod is not less than 20 cm.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The utility model controls the opening and closing of the clamping rod through the gripping part, so that the clamping rod drives the clamping piece to clamp foreign objects. The clamping piece has a barbed notch and a pointed head, which is conducive to the clamping piece extending into the small clamping gap and can help to hook out foreign objects in the clamping gap, thereby effectively cleaning foreign objects in the clamping gap of the production mold.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides a foreign body clamp for a wood-plastic production mold, comprising symmetrically cross-arranged clamping rods 1, two clamping rods 1 being hinged at the intersection by a rotating shaft 6, and a gripping portion 3 being provided at the end of the clamping rod 1;

[0028] The end of the clamping rod 1 away from the gripping portion 3 is connected to a clamping piece 2. By controlling the gripping portion 3 to open and close, the clamping rod 1 drives the clamping pieces 2 to expand outward or retract inward.

[0029] The head of the clamping piece 2 is formed into a pointed shape, and a notch 5 is provided on the side of the clamping piece 2 close to the head to form a barb.

[0030] During actual use, foreign objects with smooth surfaces may be stuck in the production mold. In order to prevent them from slipping during the clamping process, anti-slip stripes 4 are provided on the inner and outer walls of the clamping pieces 2. The anti-slip stripes 4 on the two clamping pieces 2 are staggered to increase the friction between the clamping pieces 2 and the foreign objects.

[0031] In the actual production process, foreign objects are easily stuck in the tiny gaps of the mold. In order to enable the clamping rod 1 to extend into the tiny gaps to hook out foreign objects, the thickness of the clamping rod 1 gradually decreases along its own length so that it will not be stuck during the process of extending into the gaps, and the thickness of the clamping rod 1 near the end of the clamping piece 2 is consistent with the thickness of the clamping piece 2.

[0032] If the head of the clamping piece 2 is pointed and straight, the clamping instability problem will occur during the clamping process due to the small contact surface. In order to increase the clamping surface area of ​​the clamping piece 2, the head of the clamping piece 2 gradually bends toward the side with the notch 5, which helps to better control and grasp the object during operation.

[0033] Molds with more complex structures usually contain deeper gaps. In order to allow the clamping rod 1 to penetrate deep into the gaps, the length of the clamping rod 1 must be no less than 20 cm. The specific length of the clamping rod 1 needs to be adjusted according to different molds and the size of the mold gap.

[0034] When in use, the staff holds the gripping portion 3 to control the two clamping pieces 2 to close in order to increase the hardness of the clamping pieces 2, and then extends the end of the clamping rod 1 with the clamping piece 2 into the clamping gap to hook out foreign objects. Since the clamping piece 2 is bent to one side and has a barbed notch 5 at its head, it can further help to hook out foreign objects from the clamping gap;

[0035] After hooking out the foreign object, hold the gripping portion 3 to control the clamping piece 2 to clamp the foreign object out of the production mold.

[0036] In summary, the utility model addresses the problem that the existing technology cannot clean foreign objects in the gap of the production mold, and designs a wood-plastic production mold foreign object clamp. The gripping portion 3 controls the opening and closing of the clamping rod 1, so that the clamping rod 1 drives the clamping piece 2 to clamp foreign objects. The clamping piece 2 has a barbed notch 5 and a pointed head, which is conducive to the clamping piece 2 extending into the small gap and helping to hook out foreign objects in the gap, thereby effectively cleaning foreign objects in the gap of the production mold.

The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
