Description

Technical Field

[0001] The utility model relates to a device for removing plastic boxes from a male mold and stacking them, belonging to the field of plastic production. Background Art

[0002] Plastic crates are formed using injection molding machines. After molding, they need to be removed from the punch. This is a manual process that carries certain risks. Typically, a mechanical mechanism is used to push the product off the punch, allowing it to fall and then be picked up or allowed to fall onto conveyor equipment, transported to a distant location, and then manually palletized. This process can lead to problems, such as not landing squarely on the conveyor, collapsing on the ground, and even damaging the product. In order to solve this problem, the Chinese patent specification with application number: 201711187894.X discloses a robot for obliquely removing products from a mold, characterized in that: a fixed plate (1) for fixing to an injection molding machine is provided on the fixed plate (1), a cylinder plate (2) is provided on the cylinder plate (2), a cylinder (3) is provided on the cylinder plate (2) obliquely downward, a piston rod (4) capable of obliquely moving downward is provided on the cylinder (3), a connecting block (5) is fixed on the piston rod (4), a mounting plate (6) is fixed on the connecting block (5), a rigid tube (7) connected to an external exhaust device is horizontally fixed on the left and right sides of the mounting plate (6), and a suction nozzle (8) for adsorbing the product is provided at one end of the rigid tube (7). After the inclined ejector ejects the product, the cylinder drives the connecting block, along with the mounting plate and rigid tube, to move diagonally downward. The rigid tube carries the suction nozzle close to the surface of the product, which then draws the product diagonally upward from the mold's inclined ejector. This automated suction and removal replaces manual labor, improves work efficiency, and reduces the risk of operator damage due to glue issues. However, this mechanism cannot palletize plastic boxes, requiring manual work, which increases labor intensity. Utility Model Content

[0003] The purpose of the utility model is to provide a device for removing plastic boxes from a male mold and stacking them, so as to solve the problem of high labor intensity in the prior art.

[0004] In order to solve the above problems, the device for removing plastic boxes from a punch and stacking them involved in the present invention adopts the following technical solution: a device for removing plastic boxes from a punch and stacking them, comprising a frame, a conveyor device is provided on the frame, and sliding frames are assembled on both sides of the frame through guide rails, one end of the guide rail extends beyond the end of the frame, and the sliding frame has an accommodating channel, and the extension direction of the accommodating channel is consistent with the extension direction of the conveyor device. The sliding frame is provided with mounting plates that slide up and down at both ends of the accommodating channel, and the two mounting plates are respectively fixed with a pneumatic cylinder, and the piston rods of the pneumatic cylinders are relatively cantilevered and can extend into the accommodating channel, and the ends of the piston rods of the two pneumatic cylinders are provided with vacuum suction cups.

[0005] The frame is a U-shaped frame, and the conveyor belt device is arranged in a groove of the U-shaped frame.

[0006] The guide rail is arranged at the bottom of the frame.

[0007] The sliding frame includes four columns, two of which are located on one side of the frame and the other two are located on the other side of the frame. The two columns on the same side are fixed at the bottom by a crossbeam, and the four columns are connected into a whole at the top by a frame. The frame is formed by four connecting columns connected end to end and fixed, and the upper ends of the four columns are fixed to the frame.

[0008] The two ends of the mounting plate are respectively slidably assembled with two upright posts, and the two upright posts assembled with one mounting plate are respectively located on both sides of the frame.

[0009] The vacuum suction cup is an airflow negative pressure vacuum suction cup.

[0010] The utility model is provided with pneumatic cylinders on two mounting plates, and vacuum suction cups are provided on the pistons of the pneumatic cylinders. When in use, the injection molding machine is aligned with the accommodating channel, and the parts of the two guide rails extending out of the end heads of the frame are on both sides of the injection molding machine. After the mold is opened, the sliding frame moves, and the accommodating channel is in the mold opening area. One mounting plate slides, and the pneumatic cylinder thereon extends out, and the vacuum suction cup sucks the outer wall of the bottom wall of the plastic box. The mounting plate moves up to avoid the injection molding machine, and the sliding frame moves toward the frame. The other mounting plate moves, and the pneumatic cylinder thereon extends out, and the vacuum suction cup sucks the inner wall of the bottom wall of the plastic box. Then the mounting plate moves down, and the plastic box is placed on the conveyor belt device. When there are multiple plastic boxes, the plastic box is placed in the previous plastic box and stacked up. This not only solves the problem of taking out the plastic boxes, but also solves the problem of stacking. No manual intervention is required, and full automation is achieved.

[0011] The vacuum suction cup of the utility model is an airflow negative pressure type vacuum suction cup, which can realize rapid suction and release. BRIEF DESCRIPTION OF THE DRAWINGS
