Problems solved by technology

Using this method often results in uneven parting and drilling burrs
In addition, when using electric pulse processing, due to the narrow space, it is not easy to polish, and the roughness cannot meet the requirements. The existence of these factors will lead to the scrapping of the mold
Most of the existing technologies will use the manual trimming method of processing the tearing groove, but the unreasonable processing of the tearing groove will also lead to the scrapping of the mold, so reasonable processing is very important

Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0034] Figure 1-Figure 5 It is a structural schematic diagram of the sealing strip mold provided by the specific embodiment of the present invention. A sealing strip mold includes a stacked first template 1 and a second template 2 and a plurality of cavities 3 arranged side by side between the first template 1 and the second template 2, formed on the first template 1 and the second template 2 The outside of each cavity 3 between the second templates 2 is provided with an arc-shaped edge tearing groove 4 with a depth of 0.5-1 mm, which can realize manual edge removal of the mold, and the pass rate of sealing strip molding is high.

[0035] Specifically, at a distance of 0.15 mm to 0.25 mm from the cavity 3, there is an edge tearing groove 4 for manual edge removal, and a residual material groove is...

Abstract

The invention discloses a sealing strip mold and a mold processing technology and belongs to the technical field of mold processing and structural design. The sealing strip mold and the mold processing technology are designed for solving the problem that existing mold tearing groove processing is unreasonable and consequently a mold is discarded. The sealing strip mold comprises a first mold plate, a second mold plate and multiple cavities, wherein the first mold plate and the second mold plate are arranged in a stacked manner, and the cavities are formed between the first mold plate and the second mold plate side by side. A circular-arc-shaped tearing groove with the depth ranging from 0.7 mm to 0.9 mm is formed in the exterior of each cavity formed between the first mold plate and the second mold plate. According to the sealing strip mold and the mold processing technology, the appropriate tearing grooves are processed in the mold, trimmings can be well removed, and the scrap risk of the mold is reduced. The sealing strip mold is simple in processing process, and the processed tearing grooves are high in precision.

Description

technical field [0001] The invention relates to the technical field of mold processing and structural design, in particular to a sealing strip mold and mold processing technology. Background technique [0002] There are many types of molds for the existing plate sealing strips. Among them, there are multiple sets of protruding waist-shaped heterogeneous mold cores on the lower template, and multiple sets of inverted and complex-shaped grooves on the upper template. The combination is done. Using this method often results in uneven parting and drilling burrs. In addition, when using electric pulse processing, due to the narrow space, it is not easy to polish, and the roughness cannot meet the requirements. The existence of these factors will lead to the scrapping of the mold. In the prior art, most of the methods adopt the method of manual edge trimming by processing the tearing groove, but the unreasonable processing of the tearing groove will also lead to the scrapping of...
