Description
Technical field
The present invention relates to a kind of mould, and in particular to a kind of die casting and the method that die casting is carried out using the mould.
Background technology
In enterprise produces, when running into, batch is small or batch is indefinite, but during promise well such case, is cut according to metal
The mode of processing completes important aluminium or magnesium alloy member, then, production cost and production cycle will improve tens times, even more
It is high.It is the optimal path of smail investments and quick rerurn by compression mod miniaturization, the simplification of traditional sense.
By taking the aluminium alloy castings of motor base as an example, the method according to metal cutting process is obtained, then substantial amounts of to add
Work center milling workload（Containing programming）Casting cost will be made in tens times of growths；According to metal pattern gravity-assist pouring, its mould
Although cost is very low, because casting wall is too thin（2.5mm）, cause the flow velocity of molten metal too slow and can not be molded.Thus die carter
Skill is undoubtedly optimal selection.It is worth noting that, the mould generally used on horizontal plunger die casting machine, due to its shaping, is closed
Mould is oriented to and ejecting mechanism is complete, and generally uses standard die set, therefore the manufacturing cost of mould is all more than tens thousand of members.
The content of the invention
The technical problem to be solved in the present invention is to overcome the defect of prior art there is provided a kind of die casting and die casting side
Method, the structure of cast die is simply, shaping is reliable, it is smooth to be stripped, small investment, production week when using inventive die progress die casting
Phase is short, is the fast simple and direct precision casting process that produces effects.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
Have after a kind of die casting, including upper die and lower die, stripper and core, the upper mould and the lower mould matched moulds
Die cavity, the upper mould includes upper mould body and upper mould mold insert, and the upper mould mold insert is partially submerged into the upper mould body, and it is described on
Mould mold insert and the upper mold cavity of the upper mould body formation indent；The lower mould has cast gate；The upper mould and the lower mould it
Between be provided with alignment pin.
It is preferred that, the core includes at least one user installation pass core, and the user installation pass core is conehead
Spot hole core.
It is preferred that, the stripper has lower mould mounting hole, and the lower mould can be partly by lower mould mounting hole, and passes through
Part coordinate with the discharging sheet separation.
It is preferred that, provided with shunting taper hole in the middle part of the upper mould mold insert, the shunting taper hole is built with spreader, the lower mould
Middle part is provided with sprue taper hole wide at the top and narrow at the bottom, and the shunting taper hole and sprue taper hole are coaxial；The cast gate is opened in shunting
At the cooperation of cone and sprue taper hole, the cast gate is the claw type cast gate being made up of several cast gate grooves being evenly distributed.
It is preferred that, the cast gate groove is along circumferentially uniform four of sprue taper hole.
It is preferred that, the relative both sides of the upper mould are respectively provided with mould handle, and the relative both sides of the stripper are respectively provided with down
Mould handle, during matched moulds state, the upper mould handle and the lower mould handle be not overlapping.It is not overlapping to refer to upper mould handle and lower mould hand
Handle staggers at an angle, and preferably offset angular is 90 ゜
It is preferred that, the upper mould is further opened with overflow launder and air discharge duct.
A kind of method that die casting is carried out using above-mentioned die casting.
It is preferred that, the die casting is placed on full-vertical die casting machine and used.
The beneficial effect that the present invention is reached：
Upper mould can reduce manufacturing cost using upper mould body and the chimeric form of upper mould mold insert, it is to avoid electrical spark working
Work.In order to ensure that die casting stays in lower mould after die sinking, user installation pass core uses conehead point well format, whole user to be obtained
Mounting hole, gets out after being stripped.In addition, the design of cast gate groove of the present invention is easy to remove cast gate.
The present invention die casting is cheap, casting quality reliable, longer die life, overflow, exhaust conditions are good.
Small investment, with short production cycle when carrying out die casting using inventive die, is the fast simple and direct precision casting process that produces effects.It is obtained
Casting have and Horizontal type pressure mold（High investment）The equal effect of casting, but its manufacturing cost is only suitable with casting of metals mould.
Therefore, it can yet be regarded as medium and small enterprise's design of Die Casting when, a kind of structure choice merited attention.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
Die casting used in manufacture die casting as shown in Figure 1, including upper mould 1, lower mould 2, stripper 3 and core 4-1
And 4-2, as in Figure 2-4, there is die cavity 5 after upper mould 1 and the lower 2-in-1 mould of mould, upper mould 1 includes upper mould body 11 and upper mould mold insert
12, as shown in Figure 3-4, upper mould mold insert 12 is partially submerged into mould body 11, specifically, the middle part of upper mould body 11 offers mould edge
Part mounting hole 111, upper mould mold insert 12 includes the protuberance 122 that supporting part 121 and self-supporting portion 121 stretch out, upper mould mold insert
12 with upper mould body 11 when being connected, the upper mould mold insert mounting hole 111 of the insertion of protuberance 122, and the supporting part 121 of upper mould mold insert 12 has
First face relative with the upper upper surface of mould body 11, the protuberance 122 of upper mould mold insert 12 have with upper mould mold insert mounting hole 111
The second relative face of wall, and after installing, upper mould mold insert 12 and the upper mold cavity of upper mould body 11 formation indent；Upper mold cavity is
Constitute a part for die cavity.Mould has cast gate；Alignment pin 4-3 is provided between upper mould 1 and lower mould 2.In the present embodiment, alignment pin 4-
3 be the straight pin with positioning and guide effect, and two are set altogether.
Core includes at least one user installation pass core 4-1, and the user installation pass core 4-1 is conehead point pass
The conehead taper of the conehead spot hole core is 120 ゜ in core, the present embodiment, if wanting to obtain whole user mounting hole 4-1, waits to be stripped
After get out.In addition to user installation pass core 4-1, the mould of the present embodiment also includes four motor installing hole core 4-2, casting
The motor installing hole of part can rheo-die-casting shaping, without follow-up drilling.
As shown in figure 5, stripper 3 has lower mould mounting hole 31, lower mould 2 can be partly by lower mould mounting hole 31, and leads to
The part crossed coordinates with the gap of stripper 3.Specifically, as shown in Fig. 6-7, lower mould 2 includes the lower die model core 21 of protrusion, under
Model core 21 passes through the lower mould mounting hole 31 of stripper 3, and gap coordinates therewith.
As shown in Figure 2 and Figure 4, the upper middle part of mould mold insert 12 is provided with shunting taper hole 123, and shunting taper hole 123 is built with spreader
6, the lower middle part of mould 2 is provided with sprue taper hole 7 wide at the top and narrow at the bottom, and shunting taper hole 123 and sprue taper hole 7 are coaxial；Cast gate is opened in
At the cooperation of spreader 6 and sprue taper hole 7, cast gate is that the claw type being made up of several cast gate grooves 22 being evenly distributed is poured
Mouthful.Cast gate groove 22 is circumferential uniform four along sprue taper hole 7 in the present embodiment.
The relative both sides of upper mould 1 respectively set mould handle 8 on one, and the relative both sides of stripper 3 are respectively provided with mould handle 9, close
