Description

Technical Field

[0001] The utility model belongs to the field of automobile parts production, and particularly relates to an injection molding part gate waste shearing production line. Background Art

[0002] Among automobile parts, injection molding parts account for a considerable proportion. With the continuous development of the automobile industry, in addition to the increasing requirements for the output of injection molding parts, the requirements for production quality and production efficiency are also getting higher and higher. However, after the injection molding parts are formed, a gate will be left on the workpiece, and the injection molding part finished product can only be obtained after removing the gate. Since injection molding parts are usually diverse and the gate positions are different, the gates on the injection molding parts are usually sheared manually, which is time-consuming and laborious, and the production speed is relatively low. Especially when the gate on the injection molding part is thicker, shearing is even more time-consuming and laborious, and it is even easy to injure or scratch the injection molding part during the process of shearing the gate, resulting in defective products, thus making it difficult to improve the production efficiency. In addition, the quality of shearing by relying on manual labor is usually difficult to be unified, which is likely to affect the product quality. Content of the Utility Model

[0003] In order to overcome the deficiencies of the above-mentioned existing problems, the utility model provides an injection molding part gate waste shearing production line that can simultaneously shear and cut off the gate waste of multiple workpieces quickly and neatly.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0023] As Figure 1-7 Shown in the figure, the injection molded part gate waste shearing production line includes a support frame 1 with 2 layers and several groups of workpiece gate waste shearing devices 2 arranged side by side on each layer of the support frame 1. On both sides of the support frame 1, there are also respectively provided a gate waste conveyor belt 3 for receiving and conveying gate 10 waste corresponding to the number of layers of the support frame 1 and a workpiece conveyor belt 4 for receiving and conveying the workpiece 9 with the sheared gate.

Between two adjacent groups of workpiece gate waste shearing devices 2, there is also a pick-and-place manipulator (not shown) to facilitate placing and picking up workpieces for two groups of workpiece gate waste shearing devices 2 with one pick-and-place manipulator, saving equipment costs and improving production efficiency; the clamping device 7 includes a base 71 fixedly connected to the support frame 1 and a clamping cylinder 72 rotatably arranged above the base 71;

[0024] The shearing device 8 includes a heatable shearing mechanism 81 and a driving mechanism for driving the shearing mechanism 81 to move up, down, left, and right. The driving mechanism includes an inclined second base 82 fixedly connected to the support frame 1 and a horizontal driving cylinder 83 arranged above the second base 82 for driving the shearing mechanism 81 to move back and forth. The movable end of the horizontal driving cylinder 83 is also fixedly connected to the shearing mechanism 81 through two adjusting plates 84 with adjustable relative angles. A number of adjusting slots are provided on both adjusting plates 84, and an arc-shaped slot 85 is provided on at least one adjusting plate. The two adjusting plates 84 are fixed through a locking bolt. Thus, it is convenient to adjust the inclination angle of the shearing mechanism 81 relative to the horizontal driving cylinder 83 as needed to better perform precise shearing of the gate 10 for different workpieces 9; the shearing mechanism 81 includes a tool holder and a fixed blade and a shearing blade that are cooperatively arranged on the tool holder through a pin shaft. The rear end of the shearing blade is connected to the movable end of a shearing cylinder fixedly connected to the tool holder. The shearing of the gate is realized by driving the rotation of the shearing blade through the shearing cylinder; Heating blocks (not shown) are connected to both the fixed blade and the shearing blade.

Specifically, it is placed between the two support seats of the workpiece gate waste shearing device. Then, the workpiece 9 is pressed tightly by the pressing manipulator 6, the end of the gate 10 is clamped by the clamping cylinder 72, and then the gate 10 is sheared by the shearing mechanism 81. After the shearing is completed, the finished workpiece 9 is taken off by the picking and placing manipulator and placed on the workpiece conveyor belt 4, and the clamping cylinder 72 takes the gate waste to above the gate waste conveyor belt 3 and drops it.
