Abstract
The utility model provides an improved metal type cast ball mould, which is mainly composed of an upper mould, a lower mould and a hot dozzle. The utility model is characterized in that an oblique pouring channel with an angle of 30-60 DEG and a reusable and detachable hot dozzle are adopted to enhance the feeding effect of molten iron. The quality of the grinding balls is stabilized and enhanced. A plurality of grinding balls can be cast in one step due to the design of the utility model so as to enhance the production efficiency. Environment pollution is avoided because the hot dozzle is not made from mould sand.
Description
The utility model is a kind of mould of improved cast grinding ball, particularly a kind of group mould of ball casting that is applicable to.
Present domestic cast grinding ball method mainly contains three kinds: sand casting, composite mold casting, permanent mold casting.Its mould of sand casting is easy to obtain different shape and combination, but its cast sturcture is fine and close inadequately, and surface quality of continuous castings is poor, and dimensional accuracy is low, and the molten iron utilization rate is low.Since use molding sand, the consumption that has also brought sand, and floor space is big, consequences such as environmental pollution.It is sand mold that its mould of composite mold casting is generally gone up half mould, and following half mould is a metal mold.Though the grounding ball casting tissue of this mould production makes moderate progress, having in the last half mould of mould is sand mold, still is difficult to overcome the shortcoming that sand casting exists.Its cast sturcture's densification of abrading-ball that permanent mold casting is produced, grain refinement, surface quality is good, the dimensional accuracy height.But having what adopt in the hot top of metal current mold casting mould is sand mold, needs the scene operation of tiing a knot, and its heat-insulating property is also relatively poor, and the running channel of mould is horizontal cross gate, and the feeding effect of molten iron is not ideal.Therefore, there is the defective of less stable in the mill ball quality of permanent mold casting production.
The purpose of this utility model is the quality and the service life of a kind of further raising of design and stable metal mold casting abrading-ball, is applicable to the many ball castings of the band hot top combination die of group ball foundry engieering.
Accompanying drawing 1 is a structural representation of the present utility model.
The purpose of this utility model is achieved in that the metal type multi-ball casting combination mould with thermal insulation cap that is made up of patrix 3, counterdie 1, hot top 5, alignment pin 10, wedge 8 etc., it is characterized in that: adopt the perlite roughing sand, float pearl, binding agent makes peviform typing hot top 5. At hot top 5 30 °～60 ° oblique running channels 6 in angle that lead to each cast ball die cavity are set.
The utility model is because hot top 5 is fixed-type, and is easy to loading and unloading when making the casting ball, and running channel is designed to the oblique running channel at 30 °～60 ° of angles, strengthened the feeding effect of molten iron, improved the quality of product.On this basis, be provided with a plurality of casting ball-types chamber on the metal pattern, improved production efficiency greatly.
Use the utility model to cast ball, after only need upper and lower mould being aligned with alignment pin 10, load onto peviform typing hot top 5 and use wedge 8 wedgings on patrix 3, just can cast, a mould can cast out a plurality of abrading-balls.
Claims (1)
1, the many ball castings of metal mold band hot top combination die is made up of patrix 3, counterdie 1, hot top 5, alignment pin 10, wedge 8, it is characterized in that: with the perlite roughing sand, float the peviform typing hot top 5 that pearl, binding agent raw material are made, the oblique running channel 6 at 30 °～60 ° of angles leading to each casting ball-type chamber 2 is set on hot top 5.
