Description

High pressure welding ball valve valve stem sleeve disposal molding mold
Technical field
The utility model is related to a kind of mechanical manufacturing technology, especially a kind of high and middle pressure valve parts machining technology, tool Say to body it is a kind of high pressure welding ball valve valve stem sleeve disposal molding mold.
Background technology
It is well known that valve stem sleeve is the essential operating member of high and middle pressure valve, its structure is as shown in Figure 1, it is fanned Shape step processing generally use CNC milling machine is processed, and long processing time, material-removal rate is high, efficiency and inefficiencies.It must It must be improved.
Utility model content
The purpose of this utility model is to be directed to existing high and middle pressure valve valve stem sleeve high processing costs, and waste of material is serious The problem of, a kind of disposal molding mold is designed to improve processing efficiency, reduces production cost.
The technical solution of the utility model is:
A kind of high pressure welding ball valve valve stem sleeve disposal molding mold, it includes top mold frame 1, lower mold holder 2, it is characterized in that Punch-pin 3 is first mounted on upper mounted plate 4, then is fixed in top mold frame 1 by upper stress plate 5, the punch-pin 3 be equipped with for 6 end of workpiece forms two fan-shaped convex shoulders of scalloped recess, is equipped with die socket 7 on lower mold holder 2, cavity plate 8 is mounted on die socket 7 It above and by die block 9 fixes, cavity plate 8 is equipped with the scalloped recess to match with the fan-shaped convex shoulder of punch-pin 3;In die socket 7 Center is equipped with upper end and can stretch into eject the collar 10 of workpiece in cavity plate, and the lower end of collar 10 offsets with lower seat top plate 11, under The lower end of seat top plate 11 is stretched out outside lower mold holder 2.
It is connected with guide sleeve 12 in the top mold frame 1, guide post 13 is installed on lower mold holder 2, guide sleeve 12 is sleeved on In guide post 13, to ensure the linear relative movement of top mold frame 1 and lower mold holder 2.
The punch-pin 3 and cavity plate 8 is the Cr12MoV mold steel members that hardness is far above workpiece 6.
The beneficial effects of the utility model:
The utility model changes traditional processing technology, and production efficiency 100 not only can be improved using an extrusion forming Times or more, and the material at scalloped recess can be added at fan-shaped step, can significantly be dropped by the Plastic Flow of material Low waste of material.
The utility model is simple in structure, easily manufactured.
Description of the drawings
Fig. 1 is the structural schematic diagram of the valve member of the utility model.
Fig. 2 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 2.
A kind of high pressure welding ball valve valve stem sleeve disposal molding mold, it includes top mold frame 1, lower mold holder 2, and described is upper It is connected with guide sleeve 12 on mould bases 1, guide post 13 is installed on lower mold holder 2, guide sleeve 12 is sleeved in guide post 13, to ensure The linear relative movement of top mold frame 1 and lower mold holder 2.Punch-pin 3 is first mounted on upper mounted plate 4, then is fixed on by upper stress plate 5 In top mold frame 1, the punch-pin 3 is equipped with for forming two of scalloped recess fan-shaped convex shoulders in 6 end of workpiece, on lower mold holder 2 Die socket 7 is installed, cavity plate 8 is mounted on die socket 7 and is fixed by die block 9, and cavity plate 8 is equipped with the fan with punch-pin 3 The scalloped recess that shape convex shoulder matches;Being equipped with upper end at the center of die socket 7 can stretch into eject the collar 10 of workpiece in cavity plate, The lower end of collar 10 offsets with lower seat top plate 11, and the lower end of lower seat top plate 11 is stretched out outside lower mold holder 2.The punch-pin 3 and cavity plate 8 It is the Cr12MoV mold steel members that hardness is far above workpiece 6.When it is implemented, by the variation to cavity plate lower dimension, work The step fenestra of part lower part can disposal molding.Due to section view, the sector of punch-pin and cavity plate in Fig. 2 of the utility model Step is not depending on going out.The design of part finally shaped can be found in the part shape structure of Fig. 1.
When specific works, during punch-pin pushes, since workpiece cannot be moved down by the effect of collar, punch-pin is downward When movement, scalloped recess is formed in workpiece upper end, the extra material of scalloped recess moves up to form fan under the constraint of cavity plate Shape convex shoulder, is calculated by material, and the length of valve stem sleeve raw material can save the half for being equivalent to fan-shaped step height.Extrusion forming Shi Yingxian is by workpiece entirety phosphatization(Easy mold release), extruding workpiece is carried out by four-column hydraulic press and enters mold molding, it is former to save the time 100 times of Milling Machining time, it is efficient.
The parts not involved in the utility model is the same as those in the prior art or can be realized by using the prior art.
