specific example

[0031] A specific example: the width of the positioning groove provided on the center line of the alignment claw of the four-jaw chuck of the chassis is 4.03 to 4.05 mm, and the depth is 5 mm. Positioning holes with a diameter of 4 to 4.02 mm and a depth of 5 mm are provided on the two center lines of the top plate at positions corresponding to the positioning grooves. When processing, use a positioning pin with a diameter of 4 mm and a length of 8 mm to connect the above positioning groove and the above positioning hole, and then use an automatic centering instrument to center the center of the mold to ensure the center of the mold. be effectively guaranteed.

[0032] The traditional positioning operation often takes 8-12 minutes. Using this mold processing device and positioning method can shorten the positioning operation process to 2-4 minutes, which can greatly improve the processing and positioning efficiency and greatly improve production efficiency. Through the mold p...

Abstract

The invention discloses a mold machining device and a mold positioning method. The device comprises a top disc, a bottom disc, at least one pair of chucks fixed with the bottom disc, and at least one pair of dowel pins, wherein a positioning groove is formed in the middle line position of the at least one pair of chucks; a positioning hole is formed in the top disc opposite to the positioning groove; one ends of the dowel pins are fixed in the positioning groove; and the other ends are fixed in the positioning hole. The method comprises the following steps: the positioning groove is formed in the middle line position of the opposite chucks on the bottom disc, and the elongation line of the center line of the positioning groove is intersected with the center line of a cylindrical hole in the bottom disc; the positioning hole is formed in the top disc opposite to the positioning groove; when a discharge surface is required to be machined, one ends of the dowel pins are fixed in the positioning groove, and the other ends are fixed in the positioning hole, and then, the centering is performed by using an automatic centering instrument. The method can greatly improve the positioning precision of the top disc and the bottom disc, so that the mold center is guaranteed, and the double-surface machining precision of molds is guaranteed.

Description

technical field [0001] The invention relates to the technical field of device processing, in particular to a mold processing device and a mold positioning method. Background technique [0002] The mold processing device generally includes a top plate and a bottom plate. During the production process of the extrusion die, the die hole needs to be processed on both sides, and the top plate and the chassis cannot be aligned with high precision, which leads to the problem that the positioning accuracy of the top plate and the chassis cannot be guaranteed and the positioning is difficult. In the rough machining process of the mold in the prior art, the positioning of the top plate and the chassis is corrected by the scribe line of the CNC machine tool, which has the problem of large cumulative error and low efficiency, which may easily cause 0.3 to 0.5 mm misalignment of the two ends. The die hole produces step defects, and in the subsequent finishing of the CNC machine tool, it...
