Description

A kind of process modeling structure using graphitization expansion feeding HWS calipers
(1) technical field:
The caliper class product that the utility model produces primarily directed to HWS, mainly by this process structure, utilizes spheroidal graphite The graphitization expansion characteristic of cast iron prevents caliper fuel feed hole shrinkage porosite nearby.
(2) background technology:
In existing caliper class product foundry production, to solve shrinkage porosite near fuel feed hole, position is produced using in shrinkage porosite Place's increase chill, rising head increase the rising head at cylinder head and riser neck, make its solidification mode prevent shrinkage porosite from producing in consecutive solidification It is raw.But increase rising head or increasing rising head and riser neck greatly reduce the product yield of product, while increase riser neck to production The subsequent treatment of product brings very burden, increases the labor intensity of worker, reduces the market competitiveness of company, is unfavorable for pushing away Move the energy-saving and emission-reduction of country.
Structure at caliper class product oil filler point is complex and wall herein is thicker, modulus of the modulus compared with other positions Greatly, iron liquid is in process of setting, and final set, carries out feeding without the iron liquid of abundance and easily form shrinkage porosite herein.In order to prevent The generation of this phenomenon, by adjusting process structure, its contraction is offset using the graphitization expansion of spheroidal graphite cast-iron.
(3) utility model content:
The purpose of this utility model is to provide a kind of process modeling structure using graphitization expansion feeding HWS calipers, It can solve the problem that the deficiencies in the prior art, and one kind is simple in construction, easy to make, feasibility is high, the technique that can greatly improve product Yield rate.
The technical solution of the utility model:A kind of process modeling structure using graphitization expansion feeding HWS calipers, it is special Sign be it using one side independently enter water, by template, sprue cup, sprue, cross gate, strainer core, ingate, enter molten iron piece, Rising head, riser neck and casting die cavity are formed, and the sprue cup connects sprue;Sprue bottom directly communicates with cross gate;Institute Cross gate is stated to be connected with the ingate shunted by strainer core;Use between the ingate and connect into molten iron piece;The rising head with Ingate is connected;The rising head side is provided with riser neck, and riser neck communicates with casting die cavity;It is the sprue cup, strainer core, straight Running channel, cross gate, enter molten iron piece, ingate, rising head, riser neck and casting die cavity in template;After the template matched moulds Sprue cup, strainer core, sprue, cross gate, enter molten iron piece, ingate, rising head, riser neck and casting cavity portion and form sky Chamber.
Into cuboid after two pieces of template matched moulds, sprue is round;The ingate is that section is trapezoidal Rectangular cavities, it is Thin Rectangular cavity to enter molten iron piece, and rising head section is trapezoidal, and rising head throat area is trapezoidal.
Described two casting die cavities are adjacent and a rising head is shared when being set up in parallel, and two sides of the rising head are set respectively There is riser neck, riser neck communicates with two casting die cavities respectively.
The course of work of the present utility model:
A set of casting pattern includes two block models, and for model after sand mo(u)ld is printed off in moulding respectively, two pieces of sand mo(u)lds carry out matched moulds, matched moulds Sprue cup, strainer core, cross gate afterwards, enter molten iron piece, ingate, rising head, riser neck and casting portion and form cavity, molten iron is most Sand mo(u)ld is first entered by sprue cup, first reaches sprue cup base, reaches cross gate and strainer core afterwards, by entering molten iron piece piece flow direction Ingate, rising head is reached afterwards, by being full of casting and rising head after riser neck, finally fill up whole die cavity.
Superiority of the present utility model:The planform is simple, is easy to make, and coordinates spheroidal graphite cast-iron graphitization expansion self-complementary Contracting characteristic, the number of rising head can be reduced and reduce the size of rising head so that the product yield of product greatly improves, and reduces work The labor intensity of people, improves the market competitiveness.
(4) illustrate:
Fig. 1, Fig. 2 are a kind of process modeling structure using graphitization expansion feeding HWS calipers involved by the utility model Template schematic diagram.
In figure:1 is sprue cup, and 2 be cross gate, and 3 be strainer core, and 4 be ingate Ia, and 5 be into molten iron piece, and 6 be ingate Ib, 7 be ingate IIa, and 8 be ingate IIb, and 9 be rising head, and 10 be riser neck, and 11 be casting die cavity.
