Description

Technical Field

[0001] The present invention belongs to the field of modular machine tools, and in particular relates to automatic positioning processing equipment and an automatic positioning processing method for a mold splicing core. Background Art

[0002] During mold casting, it's difficult to integrate the mold and core into a single piece for molds with complex cavities and cores. Therefore, the mold and core must be cast separately, then clamped and positioned on a modular machine tool. The molds are then assembled together using an assembly robot.

[0003] At present, when the mold core is positioned and spliced ​​by a modular machine tool, due to the spatial combination formed by the assembly robot and other components on the modular machine tool, the mold needs to be transported to the edge of the modular machine tool through suspension, lifting and other equipment, and then manually pushed to the positioning processing position in the middle of the machine tool. Most molds are cast from metal materials and are heavy, which makes it more laborious to manually push and adjust the mold position, and easily leads to inaccurate mold position adjustment, thereby affecting the splicing accuracy of the mold core.

A guide groove 58 is opened at the bottom end of the slide rail 55, and a connecting strip 59 fixedly mounted between the sliding seat 512 and the slider 510 is slidably mounted in the guide groove 58. When the clamping and positioning mechanism 5 is working, the clamping and positioning bidirectional screw rod 57 is driven to rotate by the clamping and positioning motor 56.

10. A method for automatically positioning a mold splicing core, using the automatic positioning processing equipment for mold splicing core according to any one of claims 1 to 9, characterized in that: The specific steps are: First, the mold to be processed is placed on the outer edge of the splicing positioning plate, and the mold is rolled and supported by the rollers on the outer side of the splicing positioning plate. Then, the rotary drive assembly drives multiple rollers to rotate synchronously toward the inside of the machine tool, so that the mold is rolled toward the inside of the machine tool through the rollers until the mold reaches the splicing processing position; Then, the clamping drive assembly drives the two sets of clamping assemblies to move toward each other and gradually close. When moving and closing, the clamping assembly first drives multiple rollers to move downward synchronously and hide inside the splicing positioning plate, so that the mold can be placed directly on the top surface of the splicing positioning plate. Then, the clamping assembly abuts against the end of the mold, thereby clamping and fixing the mold through the cooperation of the two sets of clamping assemblies. Then the mold core is clamped and spliced ​​into the mold cavity by the splicing robot to complete the mold splicing process; Finally, the clamping drive assembly drives the two sets of clamping assemblies to move in opposite directions to open and release the clamping of the mold. At the same time, the roller resets and lifts the mold upward, and the mold is rolled and supported again. The rotation drive assembly then drives multiple rollers to rotate synchronously toward the outside of the machine tool, so that the mold is rolled to the outside of the machine tool through the rollers to facilitate the subsequent removal of the mold from the machine tool.
