Description
Technical field
The utility model belongs to casting field, is specifically related to a kind of chilling block device using in sand casting.
Background technology
The shape matching of foundry goods is complicated, and difference in size is very large, and the difference of wall thickness may be very remarkable, but often has local thick major part, and these positions are under sand casting condition, and the heat of contained liquid metal is many, forms so-called thermal center.The molten metal at thermal center place, in process of setting, solidifies slowly than molten metal around, tends to produce the defects such as shrinkage porosite, shrinkage cavity.The most frequently used solution is near thermal center, to lay chill at present, so-called chill is the block solid of being made by materials such as cast steel, cast iron, graphite, copper, because chill has stronger heat storage capacity, can accelerate the cooling of foundry goods thermal center place, thereby prevent the generation of shrinkage porosite, shrinkage cavity.
But chill of the prior art is mostly all more regular, volume is also restricted, particularly for thick and large casting or large thermal center place, only depending on the heat storage capacity of chill itself to accelerate the cooling of thermal center place is nowhere near, its reason is the heat at thermal center place to be passed out outside sandbox and goes, and does not have lasting cooling capacity.
For solving appeal problem, authorize and to have announced a kind of external chill and external chill system for the utility model patent of CN202963412U public number, but still there are some problems in this utility model patent, as: need the cooling mediums such as water, gas, under liquid metal liquid and large heat effect, this medium can reach very soon gasification temperature generation volume and acutely expand, and has potential safety hazard; In addition its structure is also complicated, is unfavorable for that installation is fixed.
Summary of the invention
Problem to be solved in the utility model is: a kind of chilling block device is provided, can be safe and effective, and continue the heat of thermal center place liquid metal to be discharged to fast outside sandbox, simultaneously simple and practical, easy to use.
The technical scheme of the invention for solving the technical problem is: a kind of chilling block device, be arranged in sand mold, and it is characterized in that: this chilling block device comprises bowl-shape absorber, setscrew nut, heat conductive bar and radiator; Bowl-shape absorber is comprised of bowl-shape heat absorbing sheet more than a slice at least, and its bottom offers screwed hole, and the external screw thread arranging with one end on heat conductive bar adapts, and is threaded, and the openend of its bowl-shape heat absorbing sheet is placed in the heat energy-saving position that approaches foundry goods in sand mold; Setscrew nut regulates and the position of fixing bowl-shape absorber in heat conductive bar; Radiator is fin shape, and centre offers screwed hole, stretch out sandbox with heat conductive bar outside the external screw thread of the other end be connected.Bowl-shape absorber consists of 1～10 bowl-shape heat absorbing sheet, is steel or copper alloy.Heat conductive bar and radiator are made by copper alloy.
The beneficial effects of the utility model are: this kind of chilling block device, and the size and number of its bowl-shape absorber can regulate, and is applicable to the thermal center of different sizes, and its surface area is larger simultaneously, can absorb amount of heat.Heat conductive bar is used the higher Cu alloy material of thermal conductivity factor, and the heat that absorber can be absorbed is delivered to the radiator outside sandbox fast.Radiator is fin shape, and its surface area is larger can keep lower temperature and absorber to form larger temperature difference fast by heat and air or cold wind exchange simultaneously, increases the capacity of heat transmission.In sum, this chilling block device has been realized the heat at thermal center place has been delivered to outside sandbox fast, and thermal center has been played to the effect of lasting cooling, simultaneously safe and reliable again, practical and convenient.
