Abstract
The utility model discloses a subtract heavy formula core box, it contains the core box, the bottom of core box is provided with shooting hole, the bottom of core box has four to subtract the pouring weight, four through the bolt fastening subtract the pouring weight with the shooting hole noninterference, four subtract the pouring weight about core box central symmetry, and the shape that subtracts the pouring weight with the core box phase -match, it adopts the aluminum product to make to subtract the pouring weight. The upper end that subtracts the pouring weight is less than the lower extreme, the mould unloading of being convenient for, is the upper end that subtracts the pouring weight 3 for the inclination of lower extreme 5. The utility model discloses an under the prerequisite of ensuring the quality of products, the maximum psammitolite weight that lightens reduces the use amount of sand, reduction in production cost.
Description
Technical field:
This utility model relates to a kind of sand cores of castings box, particularly relates to a kind of weight-loss type core box.
Background technology:
Complex-shaped currently for foundry goods fuse, that volume is bigger core, the usage amount of sand is the biggest.So on the premise of ensureing quality, the weight alleviating core is imperative, and loss of weight can reduce the usage amount of sand, thus reduces Foundry Production cost.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of reasonable in design, reduction core weight and the weight-loss type core box of reduction Foundry Production cost.
The technical solution of the utility model is:
A kind of weight-loss type core box, containing core box, the bottom of described core box is provided with sand-spraying hole, the bottom of described core box has been bolted four loss of weight blocks, four described loss of weight blocks are not interfered with described sand-spraying hole, four described loss of weight blocks are about described core box centrosymmetry, and the shape of described loss of weight block matches with described core box, and described loss of weight block uses aluminium to make.
The upper end of described loss of weight block is less than lower end, it is simple to mould unloading, the upper end of described loss of weight block is 3-5 ° relative to the angle of inclination of lower end.The quantity of described sand-spraying hole is four and is uniformly distributed along the circumference, and described sand-spraying hole is circular；One end of described core box is linear structure, and the other end is arc-shaped structure.
The beneficial effects of the utility model are:
1, this utility model is in order to, on the premise of ensureing quality, farthest alleviate core weight, reduces the usage amount of sand, reduces production cost.
2, this utility model aluminum loss of weight block is bolted on the bottom of core box, easily dismounts, convenient and swift, changes and keeps in repair facility.
3, this utility model loss of weight block upper end is less than lower end, it is simple to mould unloading, it addition, the sand-spraying hole bottom four loss of weight blocks and core box is not interfered, does not affect product quality.
4, this utility model alleviates foundry goods fuse weight, reduces the cost of materials consumed, is particularly suited for foundry goods complex-shaped, that fuse weight big and batch is big, it is easy to promotion and implementation, economic benefit is obvious.
Accompanying drawing illustrates:
Fig. 1 is the structure chart of weight-loss type core box.
Detailed description of the invention:
Embodiment: see Fig. 1, in figure, 1-core box, 2-loss of weight block, 3-sand-spraying hole.
Weight-loss type core box contains core box 1, the bottom of core box 1 is provided with sand-spraying hole 3, wherein: the bottom of core box 1 has been bolted four loss of weight blocks 2, four loss of weight blocks 2 are not interfered with sand-spraying hole 3, four loss of weight blocks 2 are about core box 1 centrosymmetry, and the shape of loss of weight block 2 matches with core box 1, loss of weight block 2 uses aluminium to make.
The upper end of loss of weight block 2 is less than lower end, it is simple to mould unloading, the upper end of loss of weight block 2 is 3-5 ° relative to the angle of inclination of lower end.The quantity of sand-spraying hole 3 is four and is uniformly distributed along the circumference, and sand-spraying hole 3 is circular；One end of core box 1 is linear structure, and the other end is arc-shaped structure.
When coremaking, sand is injected core box 1 inner chamber from four sand-spraying holes 3, is filled into its complementary space removing four loss of weight blocks 2, thus alleviates the weight of core, reduces the usage amount of sand, reduces production cost, increases economic efficiency.
The above, it it is only preferred embodiment of the present utility model, not this utility model is made any pro forma restriction, every any simple modification, equivalent variations and modification made above example according to technical spirit of the present utility model, all still falls within the range of technical solutions of the utility model.
