Description

Technical Field

[0001] The utility model relates to the field of mold processing, in particular to a positioning device for high-precision mold processing. Background Art

[0002] Mold processing is used in industrial production to obtain various molds and tools for the desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, the mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. During the mold processing process, the mold is generally positioned to facilitate subsequent processing.

[0003] In a Chinese patent, a mold processing positioning device is disclosed, and its patent number is CN219881900U. In the mold processing positioning device of the patent, it involves the field of positioning devices, including a base, both sides of the inner cavity of the base are fixedly connected with hydraulic rods, the inner side of the hydraulic rod is fixedly connected with a fixed block, the bottom of the fixed block is fixedly connected with a sliding sleeve, the top of the fixed block is fixedly connected with a fixed column, and the top of the fixed column penetrates to the top of the base and is fixedly connected with a shell. A mold processing positioning device, firstly, the mold part is placed on an L-shaped support frame, at this time, the hydraulic rod drives the fixed block to move relatively, the fixed block drives the sliding sleeve to move relatively, the sliding sleeve slides on the sliding rod through the support wheel, the synchronous fixed block drives the fixed column to move relatively, the fixed column drives the shell to move relatively, the shell drives the L-shaped support frame to move relatively through the connecting block, so that the L-shaped support frame clamps and fixes the mold part.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) The positioning device in the prior art ensures that the mold remains stable and accurate during the processing. When fixing the mold, the existing positioning device uses hydraulic pressure to push the clamping block to achieve the clamping and fixing of the mold. However, the hydraulic advance distance usually needs to be manually adjusted according to actual needs. When fixing molds of different sizes, the clamping force is difficult to control, which often causes damage to the mold surface.

[0006] (2) In the prior art, after the mold is positioned and clamped by a device, if the mold is to be rotated, the entire device is usually rotated. This operation is time-consuming and labor-intensive, reducing work efficiency. In addition, the positioning accuracy of the mold may be affected during the rotation process, increasing the risk of processing errors.

[0007] (3) In the prior art, the external shapes of some molds are different, and the clamping plates in the existing positioning devices are mostly flat. When clamping molds with irregular shapes, the clamping effect is not satisfactory, causing the mold to shift or fall off during the processing, and may also cause damage to the processing equipment and the mold itself.
