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
[0022] Such as 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 peeling plate 5 . The upper base plate 1 is located on the upper part of the lower base plate 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 cutter head 3 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 pro...

The invention discloses a flash cutting tool for rubber products. The device at least includes an upper base plate and a lower base plate. The upper base plate is provided with an upper cutter head for cutting the flash edge. The upper cutter head is provided with two Parallel blades, the lower base plate is provided with a lower cutter head and a carrier plate for cutting flash, the lower cutter head is provided with two parallel blades, and the lower cutter head is provided with a The through hole of the lower cutter head is located in the through hole and the blade on the lower cutter head is flat with the surface of the loading plate, the upper cutter head is located directly above the lower cutter head, and the blade of the upper cutter head is aligned with the The blades of the head face each other. By implementing the alignment cutting method, the flash cutting tool for rubber products can quickly and effectively process the flash, and has the advantages of simple operation, low processing cost, no residue and no damage after cutting. The rubber product obtained by using the flash half-cutting tool has a beautiful appearance and does not require secondary processing, which is of great significance for reducing the cost of enterprise quality management.
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...
