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
The present invention relates to Mould Machining and structure-design technique field, be specifically related to a kind of sealing strip mould and mould processing technology.
Background technology
Existing board-like sealing strip class mould is of a great variety, and wherein, the special-shaped core rod of waisted opposite sex lower bolster having many groups outstanding, cope match-plate pattern has the complex-shaped groove of many group back-offs, usually adopts edge to join and has combined with electric pulse.Utilize this kind of method often there will be somatotype uneven and bore burr phenomena.In addition, use electric pulse to add man-hour, due to narrow space, be not easy polishing, roughness does not reach requirement, and the existence of these factors can cause scrapping of mould.Prior art majority can adopt processing torn edges groove to carry out manual trimming Collator Mode, but torn edges slot machining is unreasonable also can cause scrapping of mould, and thus reasonably processing is very important.
