Description
Technical field
The present invention relates to the production methods of mold, and in particular to a kind of manufacture craft of MD, RB integrated mould.
Background technique
Die for shoe-sole is mainly used for injecting raw material injection completely, circulation connected pathways is equipped in mold, cooling water is recycling
Circulating cooling in connected pathways is finally cooled and shaped using the raw material in mold；And the production of existing mold mainly includes following
Several techniques and defect:
1, tradition MD molding die is mainly using upper and lower casting, and mold adds sulphur and cooling time long when Sole moulding, ratio defective product
Low, energy consumption is high.
2, the cooling-water duct in mold is set in die casting and molding using stainless steel tube, and stainless steel tube is thermally conductive/cooling system
Number is low, and loosening is easy to appear between pipeline and mold and is generated, therefore adds sulphur and cooling time longer in process of production, and energy consumption is high,
And mold gets rusty after stainless steel tube is easy to oxidize in process of production and leak/steam phenomenon occurs.
3, the cooling-water duct in mold uses sand core casting die, and the mold fraction defective is high, due to cooling-water duct
It needs to design channel sized according to product thickness and height, need to be designed using bend in turning point, when making sand core stock mould
Sand core is extremely difficult after hardly possible molding, easy fracture, and die casting form digs out, and time-consuming, and Mold Making scrappage is high；Cooling-water duct
Using sand core sizing and the cast molding of mold one, usually there is husky hole or shrinkage cavity, lead to steam/cooling water leakage, mold product
Matter fraction defective is high.
4, in addition cooling-water duct is cast using pipeline or sand core moulding, channel belong to unified specification size, and sole
Keel thickness difference 10MM or so before and after finished product, and lead to the position sulphur of finished product keel thickness because sole product vulcanization time is identical
While changing OK, the overdone situation in the thin position of finished product keel, to influence the physical property of sole product.
5, MD, RB formed combination technique in current die for shoe-sole are as follows: be first separately formed MD and RB, then pass through the two
Artificial combination, high labor cost, production capacity are low.
Summary of the invention
In place of overcoming the above deficiencies in the existing technologies, the purpose of the present invention is to provide a kind of MD, RB mono-
The manufacture craft of forming die.
The present invention is achieved through the following technical solutions: a kind of manufacture craft of MD, RB integrated mould comprising as follows
Step:
A, production circulation connected pathways model:
(1) according to the size of sole product thickness and the shape of circulation connected pathways, pass through channel analogy mould needed for 3D printing
Type；
(2) surrounding of channel analogy model is compound has certain thickness colloidal silica, and channel analogy model is by including colloidal silica packet
Portion, the thickness toward colloidal silica split into two panels silica gel along middle line, take out the channel analogy model in each silica gel, make two panels silica gel
Corresponding face, which is formed respectively, channel pattern slot, is then provided with material hole on the channel pattern slot in a piece of silica gel thereto；
(3) two panels silica gel is combined into one, it is compound after two panels silica gel channel pattern slot between just to be formed casting channel,
Emulsus calcium carbonate composite material is poured into material hole makes calcium carbonate composite material fill up the intracorporal casting channel of silica gel, to 8-10
Calcium carbonate solidifies in channel within a hour, finally dismantles colloidal silica, takes out channel physical model made of calcium carbonate, and the channel is real
Body Model is used for die casting；Intensity, hardness increase when calcium carbonate composite material meets high temperature, water dissolution are met when low temperature, convenient for punching
It washes；
B, production mold molding:
(1) mold base is made: in order to avoid casting because husky hole or shrinkage cavity occur leaking steam/water phenomenon, inset type mold base in production,
The channel physical model that step A is obtained is put into mold base model, and is fixed by channel location device, then cast mold base at
It after type is cooling, is shaken by giant and rinses mold base internal channel, since calcium carbonate composite material meets water dissolution in low temperature, made
It is formed inside mold base and runs through cyclic steam/cooling water channel；
(2) it makes mold former insert: casting to obtain required model insert by processing wooden model, after reverse scanning is processed, casting
It makes insert and is set in mold base, required mold can be obtained.
C, mold completes the process.
Preferably, the step B further includes making whole lower die, and production is recycled connected pathways model for casting entity
It is positioned in lower die model, after casting mold base molding is cooling, is shaken with giant and rinse lower die internal channel, make shape inside lower die
At through cyclic steam/cooling water channel；Lower die needed for obtaining.
Preferably, mold of the present invention includes upper die and lower die.
Preferably, insert is provided in lower die of the present invention.
MD, RB integrated mould of the present invention is integrally formed mainly for the production of secondary EVA and secondary EVA and outsole RB
Product；Mold material is aluminum dipping form；Circulation canal and aluminum dipping form are integrally formed, thermally conductive and cooling fast；Circulation canal can be according to product thickness
Thin and peripheral wall height 3D simulation mathematical analysis production, makes steam and water directly affect production, shortens the production cycle to improve
Production capacity reduces energy consumption；Mold is produced using automatic board, reduces manual operation.
Compared with prior art, the present invention have the following advantages that and the utility model has the advantages that
1, present invention circulation connected pathways designs channel layout according to sole product thickness and peripheral wall height 3D simulation mathematical analysis
And using simulation model needed for 3D printing after cross-sectional sizes, design makes mold in this way and finished product is thermally conductive and cooling is more reasonable, thus
It improves production capacity and guarantees the physical property of finished product.
2, channel pattern is done using calcium carbonate composite material and replaces original stainless steel tube, the production for substantially reducing channel is difficult
Degree and the limitation of shape thickness processing improve the thermally conductive of channel and cooling influence area, improve production efficiency and reduction
Energy consumption.
3, channel pattern is done using calcium carbonate composite material and replaces sand core model, technology difficulty and fraction defective drop significantly
It is low；Meeting the water hardness due to the material reduces, and convenient for being gone out with giant, is easier than digging out sand core.
4, lower die more conducively flexibly handles Mold Making mode using insert mode or integral way production is bumped into mold base
And guarantee mold quality, be not in leakage steam/water phenomenon and influence the production period.
5, mould intracavity gas is discharged when upper mould, lower die are equipped with vacuum road and sealing ring, more conducively formed product, is
Fine quality provides safeguard, and especially has thin effect of decorative patterns to become apparent from product surface.
6, when the mold can be used for producing RB and EVA outsole integrated molding finished product, artificial subsequent combination is not needed to mention
Height production production capacity, is greatly reduced cost of labor and relies on.
