AI Technical Summary
When producing EHY project products, errors in mold processing and assembly caused the hole positions to fail to meet the inspection requirements in one go. Traditional methods such as replacing the die sleeve resulted in wasted processing and labor costs.
The design adopts a mold with adjustable hole positions, which allows for quick adjustment of the product hole positions by inserting a soft sleeve on the outside of the die sleeve. The soft sleeve and anti-rotation pin are used for positioning, avoiding the need to replace the die sleeve.
It enables rapid hole position changes, saving processing and labor costs, while improving the convenience of maintenance and management.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts mould, specifically is a hole position mould that can change. BACKGROUND
[0002] At present, when producing EHY project products, since the project product adopts automatic welding when welding, the product profile and hole position are required to be high, and the hole position needs to be centered during detection, but since errors are caused in the mould machining and assembly process, the product cannot be detected once, wherein the EHY-501015214AA product production process has multiple hole positions that need to be changed and optimized, and the traditional replacement of the concave die sleeve and the change of the square insert will cause waste of the processing cost and the labor cost to different degrees. SUMMARY
[0003] In view of the technical problems of the existing multiple hole position changing, the utility model provides a hole position mould that can change. The product hole position can be quickly changed by the way of inserting a soft sleeve outside the original concave die sleeve, and the mould not only saves the processing and labor cost, but also ensures the convenience of later maintenance and management.
[0004] The technical problems to be solved by the utility model are solved by the following technical solutions:
[0005] A hole position mould that can change, comprising a lower die plate, a concave die sleeve arranged on the lower die plate, a soft sleeve arranged between the lower die plate and the concave die sleeve, the concave die sleeve being embedded in the soft sleeve, and the soft sleeve being mounted on the lower die plate.
[0006] As a further improvement of the utility model, a soft sleeve mounting groove is processed on the lower die plate, and the soft sleeve is embedded in the soft sleeve mounting groove.
[0007] As a further improvement of the utility model, a first anti-rotation pin for preventing rotation is arranged on the concave die sleeve and matched with the soft sleeve.
[0008] As a further improvement of the utility model, a second anti-rotation pin for preventing rotation is arranged on the soft sleeve and matched with the lower die plate.
[0009] As a further improvement of the utility model, the soft sleeve is a 45 steel soft sleeve.
[0010] The utility model has the beneficial effects that:
[0011] The utility model provides a hole position mould that can change, and the product hole position can be quickly changed by the way of inserting a soft sleeve outside the original concave die sleeve, so that the processing and labor cost are saved, and the convenience of later maintenance and management is ensured. BRIEF DESCRIPTION OF DRAWINGS
[0012] The utility model is further illustrated below in combination with the drawings and embodiments:
[0013] Figure 1 It is a structure schematic diagram of the original state of the mold.
[0014] Figure 2 It is a structure schematic diagram of the utility model.
[0015] In the drawings:
[0016] 1, lower die plate; 2, concave die sleeve; 3, first anti-rotation pin; 4, soft sleeve; 5, second anti-rotation pin. Specific implementation
[0017] In order to make the technical means, creation features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with the drawings and embodiments.
[0018] As shown in the drawings, it is a structure schematic diagram of the original state of the mold, and as shown in the drawings, it is a structure schematic diagram of the utility model. Figure 1 Figure 2
[0019] It mainly includes lower die plate 1, concave die sleeve 2, first anti-rotation pin 3, soft sleeve 4 and second anti-rotation pin 5. The lower die plate 1 is numerically controlled and finely processed with a soft sleeve mounting groove for embedding the soft sleeve 4, and the second anti-rotation pin 5 is arranged on the soft sleeve 4, embedding the soft sleeve 4 into the soft sleeve mounting groove and positioning and preventing rotation through the second anti-rotation pin 5.
[0020] The concave die sleeve 2 is embedded into the soft sleeve 4, and the first anti-rotation pin 3 is arranged on the concave die sleeve 2 and positioned and prevented from rotating through the first anti-rotation pin 3.
[0021] The concave die sleeve 2 is a standard part, made of SKD11 material, and is relatively high in price, while the soft sleeve 4 only needs to be cut by a 45# steel wire and is relatively low in cost. Therefore, when the hole position is changed subsequently, the concave die sleeve 2 does not need to be replaced, and the soft sleeve 4 only needs to be cut into an eccentric sleeve and mounted.
[0022] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
