Description

Technical Field

[0001] The present invention belongs to the technical field of die cutting, and in particular relates to a hardware mold for punching sleeve holes. Background Art

[0002] Die cutting is to laminate materials together, and use a mold to punch once or multiple times to remove waste materials and retain the product area. There are mainly two categories of die cutting machines: one is a round knife die cutting machine, and the other is a flat knife die cutting machine. The round knives used on round knife die cutting machines are relatively expensive, and are usually not considered when making samples or the total quantity is small. That is, round knives are more suitable for products with large demand and complex processing technology. Flat knife die cutting machines are more commonly used, and flat knife die cutting machines are generally selected for products with small sample making or small total quantity.

[0003] Currently, automation is the trend, and more than 80% of product customers use automated machines for mounting. These products have requirements for typesetting and the gaps between products. Especially for die cut parts used on mobile phones, the products are small (generally with dimensions not exceeding 10MM), and have relatively high requirements for the accuracy of the gaps, and the tolerance is generally controlled within ±0.2MM (or even smaller). Due to the error in the material support of the die cutting machine, if relying solely on the material support of the machine, the tolerance cannot be achieved, and there will be steps with up and down fluctuations on the material tape.

[0004] A hardware mold is a special tool installed on various presses in industrial production. Through pressure, metal materials or other materials are used to produce parts or products of the required shape. Such special tools are collectively referred to as hardware molds.

[0005] The upper and lower plates are used in a matching manner, and the pitch is the sum of the length of a single-row product and the gap (if multiple rows are made at one time, multiply this value by the number of rows). This method is when punching and cutting holes, the guide posts are simultaneously inserted into the positioning holes of the previous mold, so as to ensure the gap between products and stably punch the products. Usually, the tolerance is within ±0.1MM.

[0006] As Figure 4 shown, both ends of the upper surface of the upper template 300 are punching sleeve hole areas 400. The punching sleeve hole areas 400 are integral with the overall hardware mold, and the hole gap is fixed and cannot be adjusted arbitrarily. Therefore, when punching products with different pitch or gap requirements, it is necessary to replace the mold or re-open the mold, increasing the cost.

[0007] CN205020647U discloses a metal mold for processing parts with inner frames, including a relatively movable upper template and a lower template, a cutting die provided on the upper template, and a concave die provided on the lower template. A plurality of inner frame blades corresponding to the inner frames on the parts with inner frames are provided on the cutting die. The distance between adjacent inner frame blades is the sum of the distance between corresponding adjacent inner frames on the parts with inner frames and the skip distance. A groove corresponding to the inner frame blade is provided on the top surface of the concave die. This application only improves the precision and still can only punch products with one gap requirement. Summary of the Invention
