Abstract
The invention discloses an extrusion casting mould for an automobile clutch housing. The extrusion casting mould comprises a movable molding board, a movable mould cavity, a molding slide block, a molding slide block base, an oil cylinder and a fixed mould. Through incompatible characteristic of the titanium and the aluminum alloy, titanium is coated on the surface of the mould corresponding to the surface with high casting smoothness, which is not mechanically processed subsequently, so that the aluminum alloy is prevented from bonding with the movable mould core; when the casting piece and the movable mould core are separated, the surface of the casting piece is guaranteed to be complete, and the smoothness is guaranteed. The movable mould core has no mould lifting inclination, a cooling water slot is formed in a position, close to a material handle, of the molding slide block, so that the upper thermal expansion and the lower cold shrinkage of the casting time are caused within a short time; micro demolding taper is formed due to temperature difference between upper and lower parts of the casting piece, so that the inner cavity of the casting piece has no mould lifting inclination, thereby obtaining the casting piece with high dimension precision and smoothness.
Description
Technical field
The present invention relates to a kind of die casting die, particularly about a kind of automobile clutch shell squeeze casting mould.
Background technology
Clutch is widely used in automobile industry, is the important spare part of automobile, in automobile transmission power and motion process, plays requisite effect, and at present, it has been compression casting by traditional gravitational casting progress that automobile clutch shell is shaped.Adopt the clutch housing that extrusion process is produced, there is pattern draft in foundry goods, core cavity dimensional accuracy is poor.Hyundai Motor requires that bell housing intracoelomic cavity is spline, do not allow to there is pattern draft, and surface smoothness will be got well, and has not allowed to pull, and these are all difficult to solve in existing Die Casting technique; In addition during die casting clutch housing, because cast-internal has a large amount of pore, cannot carry out subsequent heat treatment, mechanical castings cannot improve.
Summary of the invention
The present invention seeks to the defect for above-mentioned prior art, a kind of automobile clutch shell extrusion casint shaping dies is provided.Make after extrusion casint is shaped, bell housing intracoelomic cavity is without pattern draft, and dimensional accuracy is high, surface smoothness is high and the requirement that nothing is pulled.
For achieving the above object, the present invention takes following technical scheme:
Manufacture without pattern draft dynamic mould core, highly polished and do not carry out die surface titanizing corresponding to follow-up mach surface at foundry goods, by titanium and aluminium alloy not affinity characteristic, aluminium alloy and dynamic mould core bonding can be prevented, when foundry goods is separated with dynamic mould core, ensure the complete and fineness of cast(ing) surface.Bosh is offered near material handle position at shaping slide block, dynamic model moves up water flowing cooling in process, foundry goods bottom is cold faster than top, cause top " heat expansion " and bottom " shrinkage " of short time, form small draw taper by the foundry goods top and the bottom temperature difference, realize core cavity without the pattern draft demoulding.
A kind of automobile clutch shell squeeze casting mould, comprising: moving platen, dynamic mould core, shaping slide block, shaping take-up housing, oil cylinder, cover half.Described shaping slide block is the some shaping slide block compositions with decile in full circle, these shaping slide blocks are separately fixed on shaping take-up housing, both can the T-slot in moving platen move, described shaping take-up housing is connected with the piston of oil cylinder, and the radial motion in the course of the work of shaping slide block realizes by the oil cylinder piston be connected on shaping take-up housing.
The present invention has following distinguishing feature and beneficial effect: 1) highly polished at foundry goods and do not carry out die surface titanizing corresponding to follow-up mach surface, by the not affinity characteristic of titanium and aluminium, realize being separated of die surface and cast(ing) surface, ensure that foundry goods is highly polished and do not carry out the complete and fineness in follow-up mach surface; 2) by the control to the mold temperature short time, produce small pattern draft, realize core cavity without the pattern draft demoulding; 3) automobile clutch shell produced through the technology of the present invention can heat-treat strengthening further, effectively improves the mechanical property of foundry goods.
The present invention also can be widely used in the extrusion casint process of various cup-shaped, sleeve shaped foundry goods.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and concrete enforcement, the present invention is further described.
Fig. 1 is structural representation of the present invention, in figure:
1-dynamic mould core, 2-push rod, 3-foundry goods, 4-shaping slide block, 5-moving platen, 6-parallels, 7-is loosed core oil cylinder, 8-shaping take-up housing, 9-cover half, and 10-expects handle, 11-tup, 12-barrel, 41-bosh;
Fig. 2 is certain automobile clutch shell sketch of embodiment.
Detailed description of the invention
As shown in Figure 1, a kind of automobile clutch shell squeeze casting mould, comprising: moving platen 5, dynamic mould core 1, shaping slide block 4, shaping take-up housing 8, oil cylinder 7, cover half 9.Described dynamic mould core 1 is without pattern draft, and ti coat on diamond, prevents aluminium alloy castings and dynamic mould core 1 from boning, and when foundry goods 3 is separated with dynamic mould core 1, ensures the complete and fineness in foundry goods 3 surface.By offering bosh 41 at shaping slide block 4 near material handle 10 position, moving platen 5 drives shaping slide block 4 and shaping take-up housing 8 to move up water flowing in process, the cooling of foundry goods 3 bottom is faster than top, cause top " heat expansion " and bottom " shrinkage " of short time, small draw taper is formed by the foundry goods 3 top and the bottom temperature difference, when oil cylinder piston drives shaping take-up housing 8 to complete action of loosing core, foundry goods 3 ejects rapidly by push rod 2, realize foundry goods 3 inner chamber without the pattern draft demoulding, thus obtain high dimensional accuracy foundry goods 3.Described shaping slide block 4 is the some shaping slide block compositions with decile in full circle, shaping slide block is the level of state, shaping slide block 4 number in the present embodiment is two pieces, shaping slide block 4 is separately fixed on shaping take-up housing 8, both can the T-slot in moving platen 5 move, described shaping take-up housing 8 is connected with the piston of oil cylinder 7, and described shaping slide block 4 radial motion is in the course of the work that the piston by being connected to the oil cylinder 7 on shaping take-up housing 8 realizes.
Realize the another kind of method of the demoulding: in dynamic mould core 1, offer cooling water channel, at dynamic mould core 1 surface coating one deck heat insulating coatings in the course of work, moving platen 5 drives shaping slide block 4 and shaping take-up housing 8 to move up water flowing in process, dynamic mould core 3 is cooling meat fast, thermal insulation function due to dynamic mould core 1 surface coating makes foundry goods 3 cooling meat be slower than dynamic mould core 1, greatly reduce the package power of foundry goods 3 pairs of dynamic mould cores 1, when oil cylinder piston drives shaping take-up housing 8 to complete action of loosing core, foundry goods 3 ejects rapidly by push rod 2, thus obtain high dimensional accuracy foundry goods 3.
