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

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0035] 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 between 0.7-0.9mm, which can realize manual edge removal of the mold, and the qualified rate of sealing strip molding is high.

[0036] Specifically, at a distance of 0.15 mm to 0.20 mm from the cavity 3, there is an edge tearing groove 4 for manual edge removal, and a surplus material...

Abstract

The invention discloses a sealing strip mold and a mold machining process, belonging to the technical field of mold machining and structural design and designed for solving the problems of an existing mold that an edge tearing groove is not reasonable to machine so that the mold is abandoned and the like. The sealing strip mold comprises a first template and a second template which are arranged in an overlapped manner, and a plurality of cavities which are formed between the first template and the second template and are arrayed in parallel; a circular-arc-shaped edge tearing groove with the depth being 0.7mm-0.9mm is arranged at the outer part of each cavity between the first template and the second template. The suitable edge tearing groove is machined on the mold so that flashes can be removed well and the abandoning risk of the mold is reduced. The sealing strip mold is simple in machining process and the accuracy of the machined edge tearing groove is high.

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...
