Description

Technical Field

[0001] The utility model relates to an insert loading and unloading device for an injection molding machine, belonging to the technical field of injection molding machines. Background Art

[0002] Injection mold inserts are mold accessories used to be embedded in the core of the injection mold. In injection molded products, for some parts that need to be replaced frequently or are difficult to form, inserts can be pre-embedded in the mold to improve injection efficiency and reduce the difficulty of later processing.

[0003] The existing injection molding machine insert loading and unloading device refers to Chinese utility model CN219114610U. It can realize the synchronous movement of the insert and the injection molded product through a set of devices. Only one set of manipulators is needed to synchronously move the insert clamping mechanism and the injection molded product clamping mechanism, which not only reduces the occupied space, but also saves a set of manipulators and reduces the equipment cost. However, there are the following problems in the injection molding process: the clamping jaws are distinguished according to the objects to be loaded and unloaded, and the clamping jaws that match the size of the insert or product are needed. There is no unified clamping jaw device, which makes it more troublesome to repair and replace it later. Now there is an urgent need for an injection molding machine insert loading and unloading device to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an injection molding machine insert loading and unloading device to solve the problems raised in the above-mentioned background technology. The utility model has a reasonable structure and the design can automatically clamp the objects for loading and unloading. There is no need to distinguish between the clamps and the unified clamp device, which is relatively simple when maintenance and replacement are needed in the future.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: an injection molding machine insert loading and unloading device, including a workbench, a positioning slide hole, a hydraulic cylinder, a transmission gear plate, a transmission gear, a rotating rod and a positioning slide rod, a first frame is fixed on the left side of the upper surface of the workbench, and a second frame is fixed on the right side of the upper surface of the workbench, and the lower end surfaces of the first frame and the second frame are both provided with a mounting base;

[0006] A hydraulic cylinder is fixed to the lower end surface of the mounting base, an L-shaped support frame is fixed to the left and right end surfaces of the mounting base, a fixed box body is installed on the lower end surface of the L-shaped support frame, a rotating rod is rotatably connected inside the fixed box body, a transmission gear is fixed between the rotating rods, a transmission tooth plate is fixed to the lower end surface of the output end of the hydraulic cylinder and is meshed with the transmission gear, a connecting rod is fixed to the lower end surface of the transmission gear, clamping claws are fixed to the left and right end surfaces of the connecting rod, a positioning slide hole is opened on the front end surface of the fixed box body, a positioning slide rod is fixed to the front end surface of the connecting rod and is fit-connected with the positioning slide hole.

[0007] Furthermore, a movable hole is provided on the upper end surface of the fixed box body, the specification of the movable hole is larger than the specification of the transmission gear plate, and the two are close to each other.

[0008] Furthermore, the specification of the transmission gear matches the specification of the transmission tooth plate, and the two can be closely meshed and connected.

[0009] Furthermore, a rotation hole is provided inside the fixed box body, the inner diameter of the rotation hole is equal to the outer diameter of the rotation rod, and the two can fit and slide in connection.

[0010] Furthermore, the inner diameter of the positioning sliding hole is equal to the outer diameter of the positioning sliding rod, and the two can fit and slide together, and the positioning sliding hole is set to a circular arc structure.

[0011] Furthermore, the mounting base, L-shaped support frame, fixed box body, connecting rod, clamping claw, positioning slide hole, hydraulic cylinder, transmission gear plate, transmission gear, rotating rod and positioning slide rod constitute a clamping assembly, and the clamping assembly is provided with multiple groups, and two groups are symmetrically arranged on the lower end surfaces of the first frame and the second frame.

[0012] The beneficial effects of the utility model: the utility model is an injection molding machine insert loading and unloading device. Because the utility model adds a positioning slide hole, a hydraulic cylinder, a transmission tooth plate, a transmission gear, a rotating rod and a positioning slide rod, the design can automatically clamp the objects for loading and unloading, and there is no need to distinguish the clamping jaws. The unified clamping jaw device is relatively simple when it is needed in the later stage. It solves the problem that the original injection molding machine inserts distinguish the clamping jaws according to the objects to be loaded and unloaded, and the clamping jaws that match the size of the inserts or supplies are needed, and there is no unified clamping jaw device, which makes it more troublesome to repair and replace them in the later stage.
