Description

Technical Field

[0001] The invention relates to a mould, in particular to a refrigerator slide rail rolling burr-free cutting mould for cutting off a semi-finished product of a refrigerator slide rail. Background Art

[0002] As is known to all, there are drawers in the refrigerator body for storing items, and the drawers are connected to the refrigerator body through refrigerator slide rails. Figure 1 As shown, the refrigerator slide includes a support plate 111, and the two long sides of the support plate 111 are provided with a bent portion 112, and the bent long side away from the strip plate is provided with a flange 113. The refrigerator slide is made of a profile as a support plate, and then a bending portion and a flange are rolled out on both sides of the profile by a rolling process to obtain a semi-finished product, which is then cut by a mold.

[0003] At present, the traditional refrigerator slide rail rolling cutting die includes a lower die seat and an upper die seat; the lower die seat is provided with a horizontally arranged lower die plate, and two horizontal grooves for placing the two bent edges of the refrigerator slide rail are arranged in parallel and side by side on the upper surface of the lower die plate, and the two ends of the horizontal grooves are respectively located on a set of opposite side walls of the lower die plate, so that both ends of the first horizontal groove are open. Below the upper die seat is a horizontally arranged upper stripping plate, and the upper stripping plate and the upper die seat are matched in an upper and lower sliding state, and an upper die spring is provided between the upper stripping plate and the upper die seat. The upper stripping plate is located above the lower die plate, and there are cutting through grooves at the corresponding positions of the upper stripping plate and the lower die plate, and the cutting through groove is perpendicular to the first horizontal groove, and the cutting through groove is located between the two first horizontal grooves, and there is a cutting knife in the cutting through groove of the upper stripping plate, and the upper end of the cutting knife is fixed on the upper die seat, and the cutting knife and the cutting through groove are matched in a sliding state, and there is a first blanking channel on the lower die seat corresponding to the cutting through groove. This cutting die only uses a cutting knife to cut from top to bottom. Since the semi-finished product after rolling has a bent part, the entire cutting thickness is relatively large. During the cutting process, the waste generated by the cutting front will block the cutting knife, resulting in the cutting knife actually cutting the bent part with the waste cut first. However, the cutting knife of the die has a high hardness, and the waste has no hardness. Therefore, using a traditional die to cut the semi-finished product is prone to burrs at the cut, and an additional manual deburring station is required, which has a high production cost and low work efficiency. In addition, manual deburring will lead to poor product consistency. Summary of the invention
