Description

Technical Field

[0001] The utility model relates to the field of injection molding demoulding, and more specifically, to a multi-mold clamping mechanism. Background Art

[0002] The original injection molding demolding products and sprues need to be manually removed from the injection molding machine one by one. There are 16 products and sprues respectively. Because the sprues have a certain pre-tightening force in the mold, it is not easy to remove them by manual operation. In addition, during the injection molding process, the temperature rises for hot-melt material molding, which will make the temperature of the entire cavity machine higher. Manual operation may have safety hazards such as burns, and workers are prone to fatigue, resulting in low production efficiency. The common robot picking fixture is used in conjunction with a hardware suction cup and a clamp. However, for some products with small structures, irregular shapes, and some residual constraints on the mold, it is easy for the fixture to fail to pick up and the clamping to be unstable.

[0003] In order to avoid production safety hazards, develop a compact and exquisite injection molding product removal fixture, and now design a multi-mode clamping mechanism for multi-mode injection molding products to perform product demoulding and multi-mode clamping and removal. By using its unique configuration, the product can be clamped and removed in the cycle production of injection molding production demoulding and unloading, which reflects high-efficiency production and is more cost-effective.

[0004] Therefore, a multi-mode clamping mechanism is proposed to address the above problems. Utility Model Content

Furthermore, the linear bearing 22 arranged on the surface of the positioning block 21 is utilized to make the optical axis 23 able to perform horizontal reciprocating movement, so as to cooperate with the clamping mechanism 3 to perform clamping work.

[0024] like Figure 2 As shown, as a preferred embodiment; multiple groups of movable end support bars 24 are arranged between the two groups of optical axes 23, and one group of movable end support bars 24 is connected to the top of the T-shaped connecting block 42. Furthermore, the movable end support bars 24 arranged between the two groups of optical axes 23 and the clamping mechanism 3 are used to form a clamping assembly, which is convenient for clamping the injection molding material that needs to be demolded.

[0025] like Figure 3As shown, as a preferred embodiment; the clamping mechanism 3 includes eight groups of fixed end support plates 31 arranged on the surface of the base plate 1, and the eight groups of fixed end support plates 31 are respectively arranged opposite to the movable end support strips 24, and multiple groups of left brackets 32 and right brackets 33 are arranged on the top of the fixed end support plates 31 and the movable end support strips 24, and the left clamping plates 34 and the right clamping plates 35 are respectively arranged on the top of the left bracket 32 ​​and the right bracket 33. Furthermore, since the left bracket 32 ​​and the left clamping plates 34 and the right bracket 33 and the right clamping plates 35 arranged on the top of the fixed end support plates 31 and the movable end support strips 24 are arranged opposite to each other, when the movable end fixed strip moves, the clamping assembly forms an interchangeable open and closed state.

[0028] When the utility model is in use, the cylinder 41 drives the T-shaped connecting block 42 to move horizontally, and then the T-shaped connecting block 42 drives the movable end support bar 24 to move horizontally, so that the follower mechanism 2 moves back and forth, and then the follower mechanism 2 drives the clamping mechanism 3 to clamp, so that the injection-molded material can be demolded. The utility model can realize the simultaneous clamping and removal of multi-mode injection molded products, especially for some products with small structures, irregular shapes, and some residual constraints on the mold.
