Description

Technical Field

[0001] The invention relates to the field of automated manufacturing of injection molded products, and in particular to a manipulator fixture for automatically sucking and shearing a gate sprue of an injection molded part. Background Art

[0002] In the field of automated injection molding, a robot is usually used to automatically remove the product, and the gate trimming operation is completed manually. At present, in some improvements, the robot is first programmed to perform the grasping operation by adjusting the Y-axis up, down, left, and right movement of the grasping position, as well as the forward and backward movement of the X-axis. Then, when the product is ejected from the mold, the suction cup robot fixture takes the product out and moves it to a specific position, and cooperates with other machine fixtures to complete the automatic gate trimming operation. Compared with manual trimming, this method can not only reduce the labor intensity of workers, but also improve the consistency of the shearing of the product gate head, thereby improving the product yield.

[0003] However, this subsequent improvement method also has some problems. First, it takes up a large space and requires two sets of manipulator control systems to control the removal and shearing operations respectively. Secondly, this method is time-consuming and easily increases the failure rate of the machine, resulting in low product output efficiency, which in turn affects the product yield. In order to improve production efficiency and product quality and reduce the labor intensity of workers, it is necessary to improve automation equipment to automatically complete the product removal operation. This can not only improve production efficiency and quality stability, but also reduce labor costs and waste of labor resources. Summary of the invention

[0004] In view of the deficiencies in the prior art, the utility model provides a robot fixture for automatically sucking and cutting the gate sprue of injection molded parts, which can complete the operations of automatically sucking the product and subsequently automatically cutting the gate sprue through a set of systems.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a robot fixture for automatically sucking and shearing the gate head of an injection molded part, comprising: a base plate, a pneumatic nozzle pliers, a suction cup and a suction cup seat, a plurality of the pneumatic nozzle pliers are arranged on the base plate through nozzle pliers fixing nuts, a plurality of suction cups are respectively connected to one end of a plurality of the suction cup seats, and the other ends of the plurality of the suction cup seats are respectively arranged on the base plate through suction cup seat fixing nuts.

[0006] The utility model improves the efficiency of the use of traditional manipulators. The new manipulator fixture uses multiple suction cups to adsorb the product, and uses multiple pneumatic sprue clamps to automatically cut the product gate material head. This technical solution effectively solves the problem of consistency in product gate trimming, and realizes the operation of automatically picking up and cutting the sprue. The use of automated equipment to complete the product cutting operation can reduce dependence on human resources, reduce labor costs, reduce the labor intensity of workers, and improve the overall efficiency of the production line. At the same time, it avoids the unstable factors in traditional manual operations, improves production efficiency, and ensures the stability of product quality. BRIEF DESCRIPTION OF THE DRAWINGS
