Technical Field

[0001] This utility model relates to the field of product parts structure technology, specifically a watch case and its processing device. Background Technology

[0002] Smartwatches are high-tech products that integrate microcomputers, sensors, and communication modules into a watch form. They have multiple functions such as time display, health monitoring, activity tracking, message reminders, and payment. In the production process, smartwatches are usually manufactured in parts first and then assembled. The watch case is injection molded using molds.

[0003] Currently, most smartwatch cases are manufactured by filling the button holes near the 3H position with glue during production to facilitate injection molding. The glue is then removed by subsequent machining. This process results in a thicker wall in this area, which takes longer to complete the degreasing process and reduces the production efficiency of the watch case. Utility Model Content

The top of the positioning block 18 is inserted into the positioning groove 19. By setting the positioning block 18 and the positioning groove 19, the upper mold base 5 and the lower mold base 4 can be precisely matched to prevent misalignment.

[0023] A positioning ring 16 is fixedly installed at the bottom of the mold core 6. The lower end of the top block 13 abuts against the surface of the positioning ring 16. A compression spring 15 is sleeved on the outer surface of the top block 13. By setting the positioning ring 16, the top block 13 can be limited. By setting the compression spring 15, the top block 13 can be reset.

[0024] This utility model provides a watch case processing device, the specific working principle of which is as follows: After the upper mold base 5 and the lower mold base 4 are opened, the cylinder 17 is activated. The cylinder 17 pushes the ejector plate 7 to move upward. During the movement of the ejector plate 7, the connecting rod 12 is bent. During the bending of the connecting rod 12, the driven plate 11 is pushed to slide within the limit frame 20, so that the shaping block 10 exits from the mold cavity 8 and slides. After the ejector plate 7 moves a certain distance, the push rod 14 contacts the top block 13 and pushes it to move upward, pushing the watch case body 1 out of the mold cavity 8 and completing the demolding.
