Abstract
The utility model discloses a mold for producing a steel ball. The mold comprises an upper mold and a lower mold, wherein a joint surface of the upper mold and the lower mold is relatively provided with a plurality of concave hemispherical mold cavities; the edge of the joint surface of the upper mold and the lower mold is provided with a plurality of bulges and grooves which are matched with one another; the bulges can be clamped in the grooves; mold prying holes are respectively formed in the four side walls of the upper and lower molds; and the top of the upper mold is provided with a plurality of vent holes leading to the mold cavities. A pin positioning mode is canceled, the bulges of the lower mold are matched with the grooves of the upper mold, the four-surface positioning is adopted, and the labor intensity of a worker is reduced. By adoption of the integral structure, the mold and spherical bowl structure of the mold in the conventional mold is canceled, the service life of the mold is prolonged, and the probability of producing scrap steel balls is reduced. The used material formula is reasonable, and the mold is high-temperature resistant and wear-resistant and does not deform for a long time.
Description
Technical field
The utility model relates to the production mould field, especially a kind of mould for the production of steel ball.
Background technology
In the wear-resistant ball industry production, adopt the mould of circular matched moulds and pin locate mode now, this mould is the assembling die form, is comprised of upper and lower die body and some ball bowls, during the mould matched moulds, needs the workman to find pin accurately more, and workman's labour intensity is larger; In the use procedure, the ball bowl easily sink, and pin easily weares and teares, and makes mould dislocation occur, thereby causes the steel ball of producing to lose circle.In the prior art, mainly by pin hole again and change pin, guarantee positioning accuracy, but do like this and increased the cost that mould is safeguarded.
The utility model content
The purpose of this utility model provides a kind of mould for the production of steel ball, to solve the problem that the pin mould exists in the prior art.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of mould for the production of steel ball, include upper die and lower die, it is characterized in that: the involutory surface of described upper die and lower die is provided with a plurality of indent hemispherical die cavitys relatively, the edge on the involutory surface of upper die and lower die is provided with a plurality of projections that cooperatively interact and groove, described projection may be stuck in the groove, also have the sled nib on four sidewalls of described upper and lower mould, described patrix top also has a plurality of steam vents that lead to die cavity.
Described a kind of mould for the production of steel ball is characterized in that: described patrix crown center is provided with the boss as insulation place, has the perforate towards die cavity in the middle of the boss, and described steam vent is distributed in around the described patrix boss.
The utility model has been cancelled the pin locate mode, matches by the projection of counterdie and the groove of patrix, adopts the location, four sides, has reduced workman's labour intensity.The utility model adopts monolithic construction, and the mould of cancellation existing mold adds the ball bowl structure, has improved service life, has reduced the possibility of manufacturing scrap steel ball.The utility model uses material prescription more reasonable, high temperature resistance, wear-resistant, permanency shape.
Description of drawings
Fig. 1 is the upper and lower mould separate structure of the utility model schematic diagram.
Fig. 2 is the utility model overall structure schematic diagram.
The specific embodiment
Such as Fig. 1, shown in Figure 2, a kind of mould for the production of steel ball, include patrix 1 and counterdie 2, the involutory surface of patrix 1 and counterdie 2 is relative to be provided with a plurality of indent hemispherical die cavitys 3,4, the edge on the involutory surface of patrix 1 and counterdie 2 is provided with 4 projections that cooperatively interact 5 and groove 6, projection 5 may be stuck in the groove 6, on, counterdie 1, also have sled nib 7 on four sidewalls of 2, patrix 1 top also has a plurality of steam vents 8 that lead to die cavity, patrix 1 crown center is provided with the boss 9 as insulation place, have the perforate towards die cavity in the middle of the boss 9, steam vent 8 is distributed in around the patrix boss 9.
The utility model is applicable to the production of the steel ball of Φ 30～Φ 150, and mould adopts square structure, matches by the projection of counterdie and the groove of patrix, adopts the four sides locate mode to replace the pin locate mode.Mould is comprised of upper die and lower die, and patrix band insulation place and beginning venthole use the location, four sides, and open four at upper and lower mould outer surface and play nib.
