Abstract
A wax injection process for manufacturing mould features that the mould is made of paraffin wax by means of a mother mould and simple mould without design drawings. Its advantages are speeding up by 80%, reducing cost by 90% and weight by 5-6 times, uniform thickness of moulding cavity and beautiful mould.
Description
The present invention relates to a kind of technology, belong to the manufacture method of mould with the wax injection mfg. moulding die.
At present, along with industrial develop rapidly, mold manufacturing industry is also prosperous day by day.The difficulty of mould process designing technique is also increasing, causes the manufacturing of product more and more difficult, and often the reason owing to mould has caused the delay of producing the duration.The manufacturing step of the injection molding of introducing on the existing publication and the processing method of die cavity, have: machined, spark machined, electrotyping process, cold-extrusion shaping, poured with epoxy resin die cavity etc., can adopt the ceramic precision casting model cavity for complex-shaped surface mould, the low-melting alloy film is made; Also having a kind of is earlier timber and other simple and easy material such as land plaster etc. to be made the simple and easy transoid of mould chamber, add imitative type to machine again and mill the imitative type of processing on the equipment, more than several mould manufactures or to claim that the manufacturing process of mould does not all break away from design complicated, used machining apparatus is many, the problem that manpower, financial resources and raw material are wasteful.
The object of the present invention is to provide a kind of technology with the wax injection mfg. moulding die, complicated to overcome the prior art design, machining apparatus is many, the problem that manpower, financial resources and raw material are wasteful.
The object of the present invention is achieved like this: it is that the raw material making processes by paraffin mainly, it is characterized in that it is the mould of making by following process:
(1) making of the three-dimensional full pattern of wax pattern
1. be purchased and the industrial paraffin of weighing is made raw material,
2. place in the special-purpose melter, heat fused,
3. make required size and shapes of containers with galvanized iron sheet,
4. the paraffin after the fusing is poured in the above-mentioned galvanized iron sheet container,
5. natural condensation, the paraffin blank,
6. adopt system die model worker's process that the paraffin blank is processed into the three-dimensional full pattern of wax pattern,
(2) die sinking
1. select wax stone plate according to the size of small product size greater than the three-dimensional full pattern 30-60 of wax pattern millimeter,
2. mark the full pattern position location of wax stone plate up and down with the coordinate cross hairs at the wax stone board plane,
3. lower plate is drawn the relative standard position earlier, marks selected four jiaos of fastener hole lines and Template Location pin line again,
4. make the wax-pattern transoid die cavity of periphery greater than the three-dimensional full pattern 3-5 of wax pattern millimeter at place, full pattern location,
(3) making of wax-pattern full pattern
1. on the two ends of the imitative type cavity distance of cope match-plate pattern, get two 10 millimeters holes,
2. on full pattern and imitative type cavity die joint, be coated with and smear parting agent,
3. after full pattern was inserted imitative type cavity, stencil plate tightened up by fastener hole with screw up and down,
4. get and be placed on stirring in the wax container of a special use after paraffin dissolves and be stirred to pasty state,
5. with special syringe pasty state paraffin is injected in the wax-pattern die cavity, treats that steam vent goes out till the wax,
5. wax-pattern is opened in wax condensation after 10-20 minute,
6. repair the parting line face, first complete wax-pattern full pattern die joint is made, later process by that analogy,
7. after used operation has been imitated, open wax template and take out full pattern,
8. check die cavity, repair-deficiency is until nature, the mould made with wax injection of the present invention.
Its feature also is: described die sinking can be lower open die, curve die sinking and the die sinking of T type.
Its feature also is: the hole of beating on the cope match-plate pattern two ends is respectively into that wax hole and exhaust go out the wax hole.
The present invention compared with prior art, 1. it does not need the designing mould drawing, the master mold and the simple die that only need to make a mould get final product.2. Mold Making speed is fast, and its Production Time can be forging stock-machine and adds 1/5 of mould.3. the Mold Making cost is low, and its manufacturing cost only adds about 10% of mould for forging stock-machine.4. mold weight is light, and the profile of mould can be selected arbitrarily with the die cavity uniform wall thickness, and weight ratio forging stock-machine adds the light 5-6 of mould doubly.5. mold integral appearance exquisiteness is attractive in appearance, and the die cavity transoid designs and produces nature, is product drawing imagination and the exquisite moulding natural beauty that combines together of making, and is that forging stock-machine adds mould and can't realize.Especially the complicated more module die cavity effect of producing of geometric shape is just good more.Wax of the present invention is to recycle, and does not have loss, and it is little that technology is made scope, designs and produces conveniently, and the instrument of use is simple, and designing and producing property of association is very strong, is the direction of complex geometry mould development of manufacturing a product.
Embodiment
Be purchased and the industrial paraffin of weighing is made raw material, place in the special-purpose melter, heat fused pours into after the fusing in the galvanized iron sheet container of making according to the required size and dimension of product, and natural condensation is taken out, the paraffin blank of required product; Adopt system die model worker's process that the paraffin blank is processed into the three-dimensional full pattern of wax pattern again; Be equivalent to the mold thickness of sand casting with wax stone design, select the wax stone plate of periphery greater than the three-dimensional full pattern 30-60 of wax pattern millimeter according to the volume size of product; According to cross hairs in the wax stone board plane work branch is the coordinate location, mark wax stone plate full pattern position up and down with the coordinate cross hairs, lower plate is drawn the relative standard position earlier, mark selected four jiaos of fastener hole lines and Template Location pin line again, the three-dimensional full pattern of wax pattern is designed in the die sinking wax stone, make first false tire die joint, unnecessaryly on every side obturage very much, as long as three-dimensional full pattern parting line is concordant relatively, the main some face frame in full pattern bottom is flat just, removing the 3-5 millimeter around upper plate stencil plate full pattern decides according to the product size, get two 10 millimeters holes on the two ends of the imitative type cavity distance of cope match-plate pattern, be respectively that into wax hole and exhaust go out the wax hole, on full pattern and die joint, wipe the some parting agent, stencil plate is fastening with screw up and down, the wax injection that accent is chilled to behind the even pasty state is gone in the wax-pattern die cavity, treat that steam vent goes out till the wax, wax condensation after 10-20 minute, open wax-pattern, can process and repair the parting line face, first complete wax-pattern full pattern die joint is made into, later process by that analogy, after used operation imitated, open wax template and take out full pattern and check the die cavity repair-deficiency until nature, be the technology of the present invention with the wax injection mfg. moulding die.
