Description
Technical field
Filter base casting die riser head heat-preserving device, belong to aluminium alloy casting technique field, is specifically related to a kind of insulation construction for the filter base casting die.
Background technology
Present stage, casting for aluminium alloy castingses such as filter bases mainly completes by the filter base casting die, the casting die top is provided with rising head, aluminium liquid enters die cavity from rising head, cooling contraction occurs in the aluminium liquid in die cavity, at this moment, need the aluminium liquid at rising head place to flow to the place that needs supplementary material, complete feeding.Yet, filter base casting die rising head place under prior art does not have Insulation, make the but speed of aluminium liquid cooling in rising head, especially in temperature lower winter, aluminium liquid in rising head is because insulation is bad, and temperature reduces very fast, can't complete the feeding to foundry goods, greatly reduce feeding a casting, cause the filter base after casting to have serious flaw and quality problems; Also some filter base manufacturing enterprise has also recognized problems, and some riser head heat-preserving measures have been developed, but such measures is all above rising head, to increase other attemperators to be incubated, complex structure not only, and increased the operation of casting, reduced production efficiency, be not suitable for popularizing in an all-round way.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of high insulating effect is provided, improves feeding a casting, simple in structure and without the filter base casting die riser head heat-preserving device that increases the casting operation and insulation casting process.
The technical scheme that its technical problem that solves the utility model adopts is: this filter base casting die riser head heat-preserving device, comprise external mold and inner core, it is characterized in that: described external mold forms die cavity by the mode of left and right matched moulds, die cavity and filter base profile are complementary, inner core is placed in die cavity, die cavity top has rising head, and the rising head periphery has a plurality of insulations hole, and the insulation hole is embedded in the installation insulation material.The insulation hole is near the rising head setting, and the rational Application of insulation material has increased the heat-insulating property of rising head greatly.
Described rising head is surrounded and is formed by left and right two parts, and left part is vertical plane, uniform a plurality of insulations hole on vertical plane; Right side is divided into the concave surface of back taper, along the back taper top edge uniform a plurality of insulations of annular hole.
Described insulation hole is that cross section is the die cavity of circular, square or rectangle, and insulation material fits tightly with insulation hole inwall.
Preferably, described insulation material is heat-preservation cotton or insulation rubber.
Preferably, described inner core is the sand mold shell core, and the sand mold shell core is hollow structure, and wall thickness is 5 ~ 6mm.
Compared with prior art, the beneficial effect that has of the utility model is:
1, the rising head periphery has a plurality of insulations hole, the insulation hole is embedded in the installation insulation material, the insulation hole is near the rising head setting, the rational Application of insulation material has increased the heat-insulating property of rising head greatly, in the situation that do not increase other devices, the cooling velocity of greatly having slowed down rising head, improve feeding a casting, improve the quality of the filter base after casting, improve yield rate, increase economic benefit;
2, simple in structure, cost is low, without extra, increase parts and need not increase the casting operation, and is simple to operate, save manpower, improved operating efficiency, applicable more economically;
3, inner core adopts the sand mold shell core of hollow structure, can save the materials such as a large amount of extra large sand and resin; Aeration is good, and venting quality is good, and hydrofuge is unobstructed, and the blank forming not only reduces product cost but also greatly reduces casting flaw, improves the filter base yield rate.
