Abstract
The utility model discloses a water jacket exhausting manifold cast mould belonging to the cast technical field, which is provided with a shrink head, and is characterized in that the shrink head is of a blind feeder, and the blind feeder is of a terrace structure with small upper part and large lower part, and the lower part of the blind feeder is provided with a thin plate core, and both sides of the thin plate core are provided with a pouring channel hole forming a shrink head neck. Compared with the prior art, the mould has simple structure and convenient operation, and thoroughly resolve the hole reduction and loosening problem of the water jacket exhausting manifold casting, and improves the production rate, and adapts to the requirement of the mass production.
Description
Technical field
The utility model belongs to casting technology field, is specifically related to a kind of water jacket exhaust manifold casting mould.
Background technology
The water jacket exhaust manifold is the important spare part of high-power marine engine, complex structure, divide inside and outside two-layer, the nexine ventilation, skin is crossed water, reduces the temperature of internal layer blast pipe by outer field recirculated water, prolong the service life of exhaust manifold, having reduced the operating temperature of engine simultaneously, is the first-selected product of high-power engine, and market prospects are wide.Before calendar year 2001, domestic do not have this series products of manufacturer production, fully dependence on import.Water jacket exhaust manifold casting technique is complicated, be prone to shrinkage cavity, shrinkage porosite phenomenon, the particularly casting of the even water jacket exhaust manifold of wall unevenness, as comings water jacket exhaust manifold, wall unevenness is even, 8 isolated thermal center is arranged at vertical direction, surrounding wall is thin, and its processing is to need to place 4 blocks of chills, 4 open risers, sand mold top box height is too high, operate very inconveniently, and production efficiency is low, by the iron chill shock chilling position because of expecting the hard processing that is difficult to, so think and await this casting mould incompatibility requirements of large-scale production further to improve.
Summary of the invention
For solving the above-mentioned defective that prior art exists, it is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and eliminates shrinkage cavity, the shrinkage porosite of foundry goods, the water jacket exhaust manifold casting mould that production efficiency is high.
For achieving the above object, the technical solution adopted in the utility model is: this water jacket exhaust manifold casting mould has rising head, it is characterized in that: described rising head is a blind riser, blind riser is the big terrace with edge structure in little bottom, top, the blind riser bottom is provided with the thin plate core, and thin plate core both sides have the running channel hole that forms riser neck.
The middle part of described thin plate core has the boss that reduces the top plan puncture.
Adopt the beneficial effect of technique scheme to be: the rising head of this water jacket exhaust manifold casting mould is a blind riser by open riser, has improved the feeding efficiency of rising head, has saved iron liquid, removes chill, makes moulding more convenient, has improved production efficiency, has eliminated
Shrinkage porosite, shrinkage cavity that in the cylinder and riser neck place forms.The middle part of thin plate core has the boss that reduces the top plan puncture, and boss has increased the thickness of thin plate core, has the bottom of reduction iron liquid temp, and it is solidified before riser neck solidifies, and rising head can carry out feeding to it, recessed phenomenon occurs inhaling thereby solve end face.Compared with prior art, simple in structure, easy to operate, thoroughly solved shrinkage cavity, the shrinkage porosite problem of water jacket exhaust manifold foundry goods, improved yield rate, and the production efficiency height, adapt to requirements of large-scale production.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is a water jacket exhaust manifold casting mould structural representation.
Fig. 2 is the structural representation of thin plate core.
The specific embodiment
Comings water jacket exhaust manifold, wall unevenness is even, and weight is 25.7kg, has 8 at vertical direction
Isolated thermal center, surrounding wall is thin.Comings water jacket exhaust manifold casting mould as shown in Figure 1, has mold 1, classifying method adopts the by-level somatotype, be positioned at the thermal center position on the mold and be provided with blind riser 2, blind riser 2 is the big terrace with edge structure in little bottom, top, blind riser is located at the blind riser bottom and is provided with thin plate core 3, and thin plate core 3 both sides have the running channel hole 4 that forms riser neck, and the middle part of thin plate core has the boss 5 that reduces the top plan puncture.
Claims (2)
1, a kind of water jacket exhaust manifold casting mould has rising head, it is characterized in that: described rising head is a blind riser, and blind riser is the big terrace with edge structure in little bottom, top, and the blind riser bottom is provided with the thin plate core, and thin plate core both sides have the running channel hole that forms riser neck.
2, water jacket exhaust manifold casting mould according to claim 1 is characterized in that: the middle part of described thin plate core has the boss that reduces the top plan puncture.
