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
The present invention relates to mould processing and structure-design technique field are and in particular to a kind of sealing strip mould and mould are processed
Technique.
Background technology
Existing board-like sealing strip class mould species is various, wherein, lower template has multigroup prominent waisted opposite sex abnormity
Core rod, cope match-plate pattern has the complex-shaped groove of multigroup back-off, is generally joined using edge and completes with electric pulse combination.Using this kind of
Method often occurs that typing is uneven and bores burr phenomena.In addition, using electric pulse processing when, due to narrow space it is not easy to
Polishing, roughness does not reach requirement, and the presence of these factors can lead to scrapping of mould.Prior art majority can be torn using processing
Side groove carries out manual trimming Collator Mode, but torn edges groove processing is unreasonable to also result in scrapping of mould, thus reasonably adds
Work is particularly significant.
Content of the invention

On the other hand, the present invention employs the following technical solutions:
Further, described technique comprises the steps:
Step 1, process in described first template using the mode that roughing and polish combine and form the first die cavity,
In described second template, processing forms the second die cavity；
Step 2, added the 0.15mm～0.25mm of described first die cavity at using the mode that roughing and polish combine
Work circular arc the first torn edges groove, at the 0.15mm～0.25mm of described second die cavity Machining Arc shape the second torn edges groove；
Step 3, respectively in the external process clout groove of described first torn edges groove and described second torn edges groove；
Step 4, described first template and described second template layer poststack, described first die cavity and described second die cavity are formed
Die cavity, described first torn edges groove and described second torn edges groove form described torn edges groove.
Further, described step 1 is particularly as follows: in described first stencil design electrode, carry out roughing by electric pulse,
Leave the surplus of 0.05～0.07mm, then polish is carried out by molding cutter, formed in described first template with realization described
First die cavity.
Further, described step 2 is particularly as follows: become depth to exist with described second torn edges groove processing described first torn edges groove
Circular shape between 0.5～1mm.
Further, described step 2 is particularly as follows: the roughing of described first torn edges groove and described second torn edges groove is using little
Cutter in its own section is carried out, and drops machine-shaping by electric pulse from 0～0.5mm depth layer, and oral area leaves 0.04～
0.06mm surplus, 0.15～0.2mm surplus is left in bottom；Pass through again to drop essence with section molding cutter from 0.5～0.8mm depth layer
Machine-shaping.
The invention has the benefit that
(1) present invention passes through to process torn edges groove at the suitable distance of die cavity, and torn edges groove processing is become 0.5～1mm
Deep circular shape, is capable of the manual trimming of mould, and the qualification rate of sealing strip molding is high.
(2) present invention sets up clout groove it is ensured that overlap height is less than or equal to by the peripheral correct position in torn edges groove
0.25mm.
(3) present invention method when processing torn edges groove is improved, and the cutter using little No. than torn edges groove itself enters
Row roughing, then carry out finish-milling again, improve the precision of torn edges groove, it is to avoid traditional method not tool changing causes the report of mould
Useless, improve the qualification rate of mould processing.
