Description

Technical Field

[0001] The utility model relates to the technical field of plastic product production, in particular to a demoulding adsorption fixture for small plastic products. Background Art

[0002] In the prior art, for the production of small plastic products (such as plastic gaskets used on some buttons, etc.), after injection molding, they are first ejected by sticking ejectors, and then generally picked up and demolded by air duct blowing or a robot. However, in order to improve production efficiency, multiple products are usually injection molded together, resulting in a small spacing between injection molded products. The rear end of the suction cup on the robot is relatively large, and there is no place to place the suction cup, so it is impossible to stably grab multiple products at the same time for demolding. Therefore, only air duct blowing can be used, and the products will fly around, and some will not be blown away. The production is extremely unsmooth, resulting in occasional mold compression during mold closing, causing mold damage, thereby increasing costs. Utility Model Content

[0003] The technical problem to be solved by the embodiments of the utility model is to provide a demoulding adsorption fixture for small plastic products, so as to facilitate a robot to demould multiple small plastic products at the same time.

[0004] In order to solve the above technical problems, an embodiment of the utility model proposes a demolding adsorption jig for small plastic products, including a jig body and a fixed locking plate for an external robot, correspondingly provided with limiting bosses on both sides of the front side of the jig body, correspondingly provided with a plurality of suction nozzles in the middle of the front side of the jig body, the interior of the suction nozzle is hollow, the front side of the limiting boss exceeds the front end surface of the suction nozzle, a vacuum exhaust nozzle is provided on the back side of the jig body, an air duct connecting the suction nozzle and the vacuum exhaust nozzle is provided in the jig body, the jig body is provided with a fixed locking plate, and a plurality of screw holes are provided on the fixed locking plate.

[0005] Furthermore, a plurality of positioning posts are provided on the front side of the fixture body.

[0006] Furthermore, a balancing portion is convexly provided on the outer periphery of the front end of the suction nozzle, and the longitudinal section of the balancing portion and the front end of the suction nozzle forms a T-shape.

[0007] Furthermore, a reinforcement portion is provided on the air suction nozzle.

[0008] The beneficial effects of the utility model are as follows: the utility model is convenient for taking products and improving production efficiency; the utility model can be directly installed on the flip plate of the robot, and after the mold is opened, the robot flips to make the adsorption fixture of the utility model automatically turn to the product position, absorb the product, and then put it into a special product frame, which greatly increases the output and improves the yield rate.

[0014] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model is further described in detail below in conjunction with the drawings and specific embodiments.

[0015] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0016] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0017] Please refer to Figure 1 to Figure 3 The demoulding adsorption fixture for small plastic products of the embodiment of the utility model includes a fixture body and a fixed locking plate.

[0018] The fixed lock plate is used for connecting the flap of the external manipulator. The fixed lock plate is provided with a plurality of screw holes for conveniently connecting the flap of the manipulator by screws.

[0019] There are corresponding limit bosses on both sides of the front of the fixture body. The front of the limit boss exceeds the front end surface of the suction nozzle (exceeding 0.5mm to 3mm), so that when grabbing the product, a certain distance can be maintained between the suction nozzle and the product, avoiding the suction nozzle from directly touching the product before sucking the product, and preventing the suction nozzle from scratching the product under the drive of the robot.

[0020] A plurality of suction nozzles are provided in the middle of the front of the fixture body, and the positions of the suction nozzles correspond to the product positions on the injection mold. The suction nozzles are hollow inside, and a vacuum exhaust nozzle is provided on the back of the fixture body. An air passage connecting the suction nozzle and the vacuum exhaust nozzle is provided in the fixture body, and the fixture body is provided on the fixed locking plate.

[0021] As an implementation method, a plurality of positioning posts are provided on the front side of the fixture body to facilitate the air suction nozzle to align with the product.

[0022] As an implementation method, a balancing part is convexly provided on the outer periphery of the front end of the suction nozzle, and the balancing part and the longitudinal section of the front end of the suction nozzle form a T-shape. The balancing part prevents the position of the product from deflecting or shaking when the suction nozzle sucks the product, thereby improving the grasping efficiency.

[0023] As an implementation method, a reinforcement part is provided on the air suction nozzle, which improves the strength of the air suction nozzle and facilitates the installation and sealing between the air suction nozzle and the fixture body.

[0024] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
