Description

Technical Field

[0001] This utility model relates to the field of accessory clamping technology, and more specifically, to a quick-change batch clamping device. Background Technology

[0002] With the continuous development of society and the continuous progress of science, the production technology of injection molded parts is becoming more and more advanced. Injection molded parts refer to parts made by injection molding. However, after the injection molded parts are completed, they need to be removed from the mold. The traditional way to remove parts is by manual labor. However, after working for a long time, people are prone to fatigue, which affects the removal effect.

[0003] For example, the authorized publication number CN216400413U describes an automatic unloading mechanism for injection molding of automotive seat belt buckles. This mechanism includes a first conveying device that removes the injection molded part from the injection molding machine by clamping the sprue head; a positioning support fixture that receives the product from the first conveying device and precisely positions it; a pneumatic scissor module that extends into the positioning support fixture to cut off the sprue head; a horizontal transfer drive that drives the positioning support fixture to move between a receiving station and a picking station; a second conveying device that removes the product from the positioning support fixture at the picking station and places it on the unloading conveyor line; a finished product collection box located at the end of the unloading conveyor line; and a sprue head recovery device located on the conveying path of the first conveying device. However, due to the wide variety of injection molded parts, this mechanism cannot handle different specifications and types of injection molded parts, requiring the use of different sized mechanisms, leading to a significant increase in cost and exhibiting considerable limitations. This also greatly increases enterprise costs. Utility Model Content

[0027] The lower half-shaft 4 is fixed on the bearing plate 2, and the upper half-shaft 5 is provided on the base plate 1. An axial positioning structure for axial movement and positioning of the upper half-shaft 5 and a circumferential positioning structure for circumferential rotation and positioning of the upper half-shaft 5 are provided between the upper half-shaft 5 and the lower half-shaft 4. A drive cylinder 6 is also fixed on the base plate 1, and the motor shaft of the drive cylinder 6 is fixedly connected to the end of the upper half-shaft 5 away from the lower half-shaft 4.

[0028] Specifically, the circumferential positioning structure includes at least a semi-cylindrical block 41 integrally formed on the lower half-shaft 4, with a semi-circular groove 42 on the outer circumferential surface of the semi-cylindrical block 41; a semi-cylindrical limiting block 43 integrally formed on the lower half-shaft 4 is also provided, matching the outer contour of the groove 42, and a slot 44 is provided between the limiting block 43 and the semi-cylindrical block 41, the outer contour of the slot 44 matching the outer contour of the insertion end 411 of the semi-cylindrical block 41.
