Problems solved by technology
This method requires low investment in equipment, economical and practical, but the treatment effect is not ideal, and the requirements for self-disassembly are also high. When the thickness of self-disassembly is not ideal, the effect of flash treatment will be poor.
Because the rigidity of the steel ball is much higher than that of the rubber product, the appearance of the rubber product will be greatly damaged after the steel ball hits the rubber product during the rolling process, affecting the appearance quality of the rubber product
[0007] To sum up, it is very easy to cause flash residue and damage the body through the existing technology to deal with the flash, and the effect of flash treatment is not good.

Embodiment Construction
[0020] like figure 1 As shown, the flash cutting tool for rubber products includes an upper base plate 1 , a lower base plate 2 , an upper cutter head 3 , a lower cutter head 4 , and a stripping plate 5 . The upper substrate 1 is located on top of the lower substrate 2 . The stripping plate 5 is fixed on the upper base plate 1 by screws, and the stripping plate 5 is provided with a T-shaped through hole for accommodating the upper cutter head 3 . The upper cutter head 3 is T-shaped as a whole, one end is a cylinder with a larger diameter, and the other end is a cylinder with a smaller diameter; Two parallel blades on the upper cutter head 3 are flat with the stripping plate 5 surface when fully positioned at the smaller place of the T-shaped through hole diameter. The upper blade is provided with an arc-shaped notch at the end where the blade is provided, and the blade is located on both sides of the arc-shaped notch. The upper base plate 1 is also provided with a contour b...

The invention discloses a rubber product flash split tool, which at least comprises an upper substrate and a lower substrate. The upper substrate is provided with an upper cutter head for cutting off flash. The upper cutter head is provided with two parallel blades. The lower substrate is provided with a lower cutter head used for cutting off flash and an object carrying plate. The lower cutter head is provided with two parallel blades. The object carrying plate is provided with a through hole for containing the lower cutter head. The lower cutter head is positioned in the through hole, and the blades of the lower cutter head and the surface of the objecting carrying plate are at the same level. The upper cutter head is positioned right over the lower cutter head, and the blades of the upper cutter head are opposite to the blades of the lower cutter head. Through implement of the counterpoint cutting method, the rubber product flash split tool can be used to rapidly and effectively process flash and has advantages of simple operation, low treatment cost, no residue after cutting and no damage. A rubber product obtained by the use of the flash split tool has a beautiful appearance and requires no secondary processing, which is of great significance for reducing enterprise quality management cost.
Description
technical field [0001] The invention relates to a flash cutting tool for rubber products. Background technique [0002] Flash is the residual edge that overflows into the mold parting line or the gap of the demoulding pin during the molding process and remains on the injection molded part. [0003] In the production process of rubber products, flashes also exist on the edges of rubber products. The flashes are also formed due to the low precision of the contact surface between the punch and the die, excessive material volume, and leakage of the remaining material at the weak seal. In the prior art, there are various methods for processing the flash of rubber products, mainly including the following three methods: freehand processing, freezing processing, and roller grinding. These three methods require different hardware when used, and the effects obtained by processing are also different, and the processing costs are significantly different. [0004] (1) Hand-handling met...
