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 , 2 As shown, the flash cutting tool for rubber products includes an upper substrate 1 and a lower substrate 2 . An upper clamping assembly and a pressing and cutting plate 3 are arranged on the upper base plate 1. The whole pressing and cutting plate 3 is a flat plate structure, and is fixedly connected with the upper base plate 1 by screws. A T-shaped through hole is provided inside the upper substrate 1 , and the T-shaped through hole is composed of two sections of through holes with different diameters. like figure 2 As shown, the pressing plate 3 is provided with protrusions I4 at the end of the T-shaped through hole with a smaller diameter, and the protrusions I4 are distributed on both sides of the T-shaped through-hole and are symmetrical with respect to the center line of the T-shaped through-hole. The cross section of the protrusion I4 is triangular, and the surface facing the T-shaped through hole is flush with the inner surface of the upper...

Abstract

The invention discloses a rubber product flash press-cutting tool, which at least comprises an upper substrate and a lower substrate. The upper substrate is provided with an upper clamping assembly and a press-cutting plate. The lower substrate is provided with a lower clamping assembly and an object carrying plate. The upper clamping assembly and the lower clamping assembly form two clamping stations. Two clamping stations are formed between the press-cutting plate and the object carrying plate. Press-cutting operation is realized through the four clamping stations. Through a press-cutting method, the rubber product flash press-cutting tool is used to directly cut off flash from a rubber product, and the operation process is simple and effective. After press-cutting, there is no residue and no damage. The press-cutting treatment cost is low. The rubber product produced by the use of the rubber product flash press-cutting tool has a beautiful appearance and requires no secondary processing, which is helpful for enterprises to reduce quality management cost.

Description

technical field [0001] The invention relates to a flash pressing and cutting tool for rubber products. Background technique [0002] Flash is the remaining edge that overflows into the gap between the mold parting line or the ejector pin during the molding process and remains on the injection molded part. [0003] In the production process of rubber products, there are also flashes 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 concave die, the excessive amount of material, and the leakage of the remaining material at the weak seal. In the prior art, there are various methods for processing the burrs of rubber products, mainly including the following three types: freehand processing, freezing processing, and roller milling. The hardware requirements of these three methods are different, the effect obtained by the processing is also different, and the processing cost is obviously differen...
