Abstract
A kind of speed changer rubber piston mould, relates to a kind of rubber piston mould.To solve existing speed changer rubber piston mould in matched moulds process, because clamp force is not enough to skeleton and mould to fit tightly, sizing material can flow out under pressure, affect product quality and do not design exhaust structure because of mould, the gas produced when sizing material flows under stress can not be discharged in time, can produce sulfuration print problem at product surface.Core rod is arranged in patrix, and butterfly spring arranges in the mounting groove between patrix and core rod, and the upper cavity of counterdie is provided with gear platform near outer edge; During matched moulds, the upper surface of skeleton is closely attached to that core rod lower surface is outer peripheral to match on face, the upper cavity that lower surface is closely attached to counterdie matches on face, and the passage formed between counterdie and core rod is exhaust passage, and the inner chamber formed between patrix, core rod and counterdie is reinforced chamber.The utility model is used for shaping speed changer rubber piston.
Description
Technical field
The utility model relates to a kind of rubber piston mould.
Background technology
In use there is following defect in existing speed changer rubber piston mould: before (1) mould matched moulds, clamp force is not enough to skeleton and mould to fit tightly, in matched moulds process, sizing material can flow out under pressure, make skeleton outer surface also have sizing material, cause product (speed changer rubber piston) presentation quality defective.(2) because mould does not design exhaust structure, the gas produced when sizing material flows under pressure can not be discharged in time, can produce sulfuration print at product surface.
Summary of the invention
The purpose of this utility model is to provide a kind of speed changer rubber piston mould, to solve existing speed changer rubber piston mould in matched moulds process, because clamp force is not enough to skeleton and mould to fit tightly, sizing material can flow out under pressure, affect product quality and do not design exhaust structure because of mould, the gas produced when sizing material flows under stress can not be discharged in time, can produce the problem of sulfuration print at product surface.
For achieving the above object, the technical scheme taked is as follows for the utility model:
A kind of speed changer rubber piston mould, it comprises patrix, core rod, butterfly spring, counterdie and skeleton, described upper die and lower die are oppositely arranged up and down, described core rod is arranged in the center cavity of patrix, mounting groove is provided with between patrix and core rod, butterfly spring is arranged in described mounting groove, and described skeleton upper surface one end is attached to that core rod lower surface is outer peripheral to match on face; The upper cavity of described counterdie is provided with one for placing the gear platform of sizing material near outer edge; During matched moulds, the upper surface of skeleton is closely attached to that core rod lower surface is outer peripheral to match on face, the upper cavity that the lower surface of skeleton is closely attached to counterdie matches on face, and the passage formed between counterdie and core rod is exhaust passage, and the inner chamber formed between patrix, core rod and counterdie is reinforced chamber.
The utility model relative to the beneficial effect of prior art is:
1, owing to being provided with butterfly spring in the mounting groove between patrix and core rod, in formed product process, increase clamp force, and this clamp force is enough to the upper surface of skeleton to be closely attached to, and core rod lower surface is outer peripheral to match on face, the upper cavity that the lower surface of skeleton is closely attached to counterdie matches on face, therefore, can prevent sizing material from overflowing.
2, because mould of the present utility model is provided with exhaust passage, the bubble produced can be discharged in sizing material flow process, efficiently solve the sulfuration print problem of product.
3, the utility model has simple, with low cost, the easy to operate feature of structure, and the appearance quality of formed product using this mould to obtain meets the requirements completely.
Accompanying drawing explanation
Fig. 1 is the front view before a kind of speed changer rubber piston mould matched moulds of the present utility model;
Fig. 2 is the front view after a kind of speed changer rubber piston mould matched moulds of the present utility model;
Fig. 3 is the A place partial enlarged drawing of Fig. 1.
Wherein, patrix 1, core rod 2, butterfly spring 3, counterdie 4, gear platform 5, exhaust passage 6, skeleton 7, sizing material 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ Fig. 3, a kind of speed changer rubber piston mould, it comprises patrix 1, core rod 2, butterfly spring 3, counterdie 4 and skeleton 7, described patrix 1 and counterdie about 4 are oppositely arranged, described core rod 2 is arranged in the center cavity of patrix 1, mounting groove is provided with between patrix 1 and core rod 2, butterfly spring 3 is arranged in described mounting groove, disk spring 3 one end contacts with core rod 2, disk spring 3 other end contacts with patrix 1, and described skeleton 7 upper surface one end is attached to that core rod 2 lower surface is outer peripheral to match on face; The upper cavity of described counterdie 4 is provided with one for placing the gear platform 5 of sizing material 8 near outer edge; During matched moulds, the upper surface of skeleton 7 is closely attached to that core rod 2 lower surface is outer peripheral to match on face, the upper cavity that the lower surface of skeleton 7 is closely attached to counterdie 4 matches on face, the passage formed between counterdie 4 and core rod 2 is exhaust passage 6, and the inner chamber formed between patrix 1, core rod 2 and counterdie 4 is reinforced chamber.
Patrix 1, core rod 2, butterfly spring 3 and counterdie 4 acting in conjunction, realize axial location skeleton 7, prevent skeleton 7 axial motion and ensure formed product.During matched moulds, power is passed to core rod 2 by disk spring 3.
Further, as shown in Figure 3, described gear platform 5 is annular gear platform, can ensure that sizing material 8 is in the reinforced chamber described in the uniform inflow of circumferencial direction.
Further, as shown in Figure 1 and Figure 2, described patrix 1, core rod 2 and counterdie 4 are coaxially arranged, and can guarantee to process up-to-standard product.
The course of work: as shown in Fig. 1 ~ Fig. 3, sizing material 8 can be circular shape or elongate in shape and is placed on the gear platform 5 of counterdie 4, during matched moulds, mould closes sternly from top to bottom, under the effect of disk spring 3, power is passed to core rod 2, core rod 2 radially compresses skeleton 7, prevent the radial vibration of skeleton 7, counterdie 4 compresses skeleton 7 vertically, prevents skeleton 7 axial motion.Skeleton 7 is compressed by core rod 2, counterdie 4 and patrix 1, and sizing material 8 flows in the reinforced chamber formed by patrix 1, core rod 2 and counterdie 4 from the gear platform 5 of counterdie 4, effectively prevents the outflow of sizing material 8.Mould parting position is arranged between patrix 1, core rod 2 and counterdie 4.During sulfidization molding, mould is being vented by the exhaust passage 6 formed between counterdie 4 and core rod 2, and when preventing sizing material 8 from flowing, gas has no way of discharging, and causes product sulfuration print or product stripping difficulty, and can guarantee formed product and the demoulding.
