The mould presenting a ball shape with the internal part being hollow comprises a semicircular upper die and a semicircular lower die, wherein, the upper die and the lower die are respectively provided with an upper connection side and a lower connection side, and the lower connection side is provided with symmetrical and rotatable fixing handles; die parting surfaces are adopted at the middle parts of the upper die and the lower die, a safe edge is arranged on the die parting surface of the upper die, and a step matched with the safe edge is arranged at the corresponding position of the lower die; the top end of the upper die is provided with an eye ring, which presents a cylinder shape, and the eye ring is internally provided with a small hole which passes through the upper die. The safe edge and the step can play the functions of positioning and stabilizing the mould, and also prevent the leakage from happening to die parting surfaces, and the fixing handles can conveniently fix the upper die and the lower die.

Description

The closure ball mould

Technical field

The utility model relates to a kind of mould, especially a kind of closure ball mould that is used for making closure ball.

Background technology

Closure ball is to make with elastomeric material, rounded, inner fluid of filling certain pressure for hollow, so the shell wall of closure ball needs certain thickness, and the thickness of shell wall must be evenly, otherwise under the effect of internal pressure, sex change can take place in the position of thin thickness, thereby influences the profile of closure ball integral body easily.

Making the die joint of the mould of round sealed ball must be close to, otherwise crack occurs easily, and inner material is seeped in the slit easily, reduces through the material of budget like this and makes the shell wall attenuation of closure ball.

Summary of the invention

The purpose of this utility model provides a kind of closure ball mould of making the round sealed ball.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of closure ball mould, integral body is the sphere of inner hollow, comprise semicircular upper die and lower die, wherein, be respectively equipped with fillet and following fillet on the described upper die and lower die, following fillet is provided with the rotatable fixed handle of symmetry; Upper die and lower die are die joint in the middle of adopting, and the die joint of patrix is provided with safe edge, and the corresponding position of counterdie is provided with the step that matches with safe edge; The top of patrix is provided with handle, and handle is cylindrical, is provided with the aperture that penetrates patrix in the handle; The extending part of patrix inner surface handle is provided with bullet.Median plane with bead is a die joint, and symmetry is divided mould easily; The die joint of upper and lower mould is provided with fillet, on following fillet rotatable fixed handle is set and can makes things convenient for matched moulds; Safe edge and the step cooperatively interact are set on die joint can make things convenient for the upper and lower mould location, fixing easily in the course of the work, the phenomenon that can occur misplacing not, and the slit can not appear between upper and lower mould; The handle of the aperture that penetrates patrix is set on the top of patrix, and the convenient mould that divides can plug fixture in the aperture, in order to the fixing object of closure ball inside, makes it to keep stablizing in closure ball; The bullet of patrix inner surface makes closed container produce a conical outlet at this position, and the self-enclosed sealing device of matching embedded type forms sealing.

The fixed handle front is square, and the side is " Π " shape, and the length of medial side is the height after overlapping greater than two fillets, is provided with large diameter sleeve pipe on the rotation free end.After patrix and counterdie aligned matched moulds, the upset fixed handle was pushed down free end at the back side of fillet; It is that the line contact can be stablized patrix that free end has certain length and contacting of the last fillet back side.

As preferably, fixed handle is provided with brace, is fixed in down on the fillet by clip, and round end is near the edge of fillet down.

The edge of last fillet and following fillet be provided with toward the back side of die joint high along the limit, the stationary plane that gets out of the way fixed handle along the limit on the following fillet.

As preferably, the back side of following fillet die joint is provided with uniform reinforcement, reinforcement connected on the counterdie along limit and spherical.Reinforcement is strengthened the intensity of fillet down, keeps stable when making a whole set of mould be placed on the workbench, irregular vibration can not occur.

The edge diameter of following fillet is greater than the edge diameter of last fillet.

The tapering of bullet is 10 ° ~ 30 °.

The beneficial effects of the utility model are: the middle plane of symmetry is convenient to the branch mould as die joint, at safe edge and the step that die joint setting can cooperatively interact, can plays the effect of location and stable mould, can also prevent that crack from appearring in die joint; On the fillet rotatable fixed handle is being set down, conveniently patrix and counterdie is being fixed; Reinforcement is set on the following fillet can strengthens fillet down, when mould is placed on the workbench, keep stable; Handle is set on the top of patrix can conveniently divides mould; Sleeve pipe on the fixed handle is used for pushing down upper and lower mould, and contact-making surface is that the line contact can make the upper and lower mould matched moulds stable.
