Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a clamping structure of an injection molding machine. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding machines are the main molding equipment that use plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds.

[0003] The product after injection molding by the injection molding machine is exposed after the mold is separated, and the product is taken out by a clamping adsorption structure with a suction cup. The existing clamping adsorption structure with a suction cup is basically connected to a robotic arm and moved by the robotic arm. However, when the suction cup contacts and adsorbs the product, the clamping wall connecting the suction cup makes the suction cup contact the product without buffering. After the suction cup is squeezed to a certain extent, it no longer buffers. At this time, if there is still impact force, it is easy to impact and damage the product.

[0004] In view of this, we propose a clamping structure for an injection molding machine. Utility Model Content

[0018] The reinforcement structure includes a reinforcement strip and a slide strip;

[0019] One end of the reinforcement strip is fixedly arranged on one side of the horizontal strip;

[0020] The sliding strip is fixedly arranged on the side of the other end of the reinforcing strip;

[0026] 1. The utility model provides a connecting rod, a limit plate and a spring, so that the suction cup contacts the product after injection molding and squeezes and absorbs it under the drive of an external mechanical arm.

[0036] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0037] Embodiment 1: A clamping structure for an injection molding machine, see Figures 1 to 4 , including a connecting plate 1, a U-shaped plate 2, a horizontal bar 5, a vertical bar 7 and a suction cup 6;

[0038] The U-shaped plate 2 is fixed to the end of the connecting plate 1, and the U-shaped plate 2 is fixed to the connecting end of the external mechanical arm by bolts and nuts; the ends of the two horizontal bars 5 are symmetrically arranged on one side of the head end of the connecting plate 1 through the elastic connection structure 3; the vertical bar 7 is fixed to the head end of the two horizontal bars 5; a plurality of suction cups 6 are equidistantly arranged on the vertical bars 7, and the suction cups 6 are connected to the air pump through a hose;

[0039] The elastic connection structure 3 includes a connection rod 301, a limit plate 302 and a spring 303;

[0040] The two connecting rods 301 are symmetrically inserted into the through holes 101 symmetrically opened on the connecting plate 1; the limit plate 302 is fixedly mounted on one end of the two connecting rods 301; wherein the other ends of the two connecting rods 301 are respectively fixedly connected to one side of the ends of the two horizontal bars 5; the spring 303 is sleeved on the connecting rod 301 between the ends of the horizontal bars 5 and the connecting plate 1, and the two ends of the spring 303 are respectively fixedly connected to the ends of the horizontal bars 5 and the connecting plate 1, and the elastic coefficient of the spring 303 is selected and used by the technicians in this profession according to the actual situation.

[0041] The utility model provides a connecting rod 301, a limit plate 302 and a spring 303, so that the suction cup 6 contacts the injection molded product and squeezes and absorbs it under the drive of an external mechanical arm. When the suction cup 6 is over-squeezed, the horizontal bar 5 is forced to drive the connecting rod 301 to move relative to the connecting plate 1, and the spring 303 is compressed to generate a reaction force for buffering. This solves the problem that the clamping wall connecting the suction cup 6 causes the suction cup 6 to contact the product without buffering, and the suction cup 6 no longer buffers after being squeezed to a certain extent. If there is still impact force at this time, it is easy to impact and damage the product.

[0042] Specifically, a reinforcement structure 4 is arranged between one side of the two horizontal bars 5 and the head end of the connecting plate 1;

[0043] The reinforcement structure 4 includes a reinforcement strip 401 and a slide strip 402;

[0044] One end of the reinforcement bar 401 is fixed to one side of the horizontal bar 5 ; the sliding bar 402 is fixed to the side of the other end of the reinforcement bar 401 ; wherein the sliding bar 402 is slidably matched with the sliding groove 102 opened at the head end of the connecting plate 1 .

[0045] The utility model provides a reinforcement bar 401, a slide bar 402 and a slide groove 102, so that when the horizontal bar 5 is driven by force to move the connecting rod 301 relative to the connecting plate 1, the slide bar 402 moves relative to the slide groove 102, and the reinforcement bar 401 ensures that there is a supporting force between the horizontal bar 5 and the head end of the connecting plate 1 when the horizontal bar 5 moves, thereby keeping the horizontal bar 5 stable.

[0046] Furthermore, the reinforcement strip 401 adopts a broken line structure design, and the angle between the two ends of the reinforcement strip 401 is an obtuse angle; the bending of the reinforcement strip 401 forms a triangle, which has good stability.

[0047] Furthermore, the slide bar 402 adopts a T-shaped structure design, and the slide bar 402 is adapted to the slide groove 102. The T-shaped slide bar 402 slides stably with the slide groove 102, so that the reinforcement bar 401 remains stable when moving, and the horizontal bar 5 and the connecting plate 1 remain relatively parallel.

[0048] It is worth noting that the length of the slide bar 402 is greater than the compressed length of the spring 303 , and when the spring 303 is compressed, the slide bar 402 will not separate from the slide groove 102 .

[0049] Working principle: When using the device of the utility model, the U-shaped plate 2 is fixed to the connecting end of the external mechanical arm by bolts and nuts. The product after injection molding by the injection molding machine is exposed after the mold is separated. The suction cup 6 contacts the product after injection molding and squeezes and absorbs it under the drive of the external mechanical arm. When the suction cup 6 is over-extruded, the horizontal bar 5 is forced to drive the connecting rod 301 to move relative to the connecting plate 1, and the spring 303 is compressed. The reaction force is generated by the compression of the spring 303 for buffering. The T-shaped slide bar 402 moves relative to the slide groove 102, and the reinforcement bar 401 moves accordingly and remains stable. The horizontal bar 5 and the connecting plate 1 remain relatively parallel. The external air pump evacuates the suction cup 6, so that the suction cup 6 absorbs the product, and the mechanical arm is operated to take out the product.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
