Abstract
A kind of high and middle pressure valve valve body disposal molding mold, it is characterized in that it is mainly by upper mold（1）, lower die（2）And plug（3）Composition, plug（3）It is installed on valve body（4）Valve rod mounting hole in prevent valve body compression molding when deformed damaged；The upper mold（1）And lower die（2）Cavity and valve body（4）The shape at both ends matches；Simultaneously in upper mold（1）The upper mould core of determining valve body upper port size is installed（5）, lower die（2）The lower die mold core of determining valve body lower end mouth size is also installed（6）.The utility model creatively will be changed to disposable extrusion forming by pultrude process twice, have simple in structure, the high advantage of production efficiency.
Description
Technical field
The utility model is related to a kind of high and middle pressure valve manufacturing technology, especially a kind of high and middle pressure valve valve body is shaped
Technology, specifically a kind of high and middle pressure valve valve body disposal molding mold.
Background technology
Currently, the necking at valve body both ends, which is all made of necking machine single head, carries out necking, processing technology is complicated, needs multiple clamping
It could complete the necking at both ends with necking, this method is there are long processing time, the problem of efficiency is low, and quality is difficult to ensure, has
Necessity is improved.
Utility model content
The purpose of this utility model is that there are technique is multiple for the necking processing at the valve body both ends of existing high and middle pressure valve
It is miscellaneous, the problem of long processing time, quality is difficult to ensure, a kind of high and middle pressure valve valve body that can simultaneously both ends be carried out with shrinkage cavity of design
Disposal molding mold.
The technical solution of the utility model is：
A kind of high and middle pressure valve valve body disposal molding mold, it is characterized in that it is mainly by 3 groups of upper mold 1, lower die 2 and plug
At plug 3 is installed in the valve rod mounting hole of valve body 4 deformed damaged when preventing valve body compression molding；The upper mold 1 is under
The cavity of mould 2 and the shape at 4 both ends of valve body match；The upper mold mould of determining valve body upper port size is installed in upper mold 1 simultaneously
Core 5, lower die 2 are also equipped with the lower die mold core 6 of determining valve body lower end mouth size.
The upper mold 1 uses Cr12MoV, quenching hardness HRC58；Upper mould core 5 uses Cr12MoV, quenching hardness
For HRC53.
The lower die 2 uses Cr12MoV, quenching hardness HRC60, lower die mold core 6 to use Cr12MoV, quenching hardness
For HRC63.
The plug 3 uses Cr12MoV, quenching hardness HRC63, to prevent valve body centre trepanning position in pressing process
The place of setting and stress and deform.
The beneficial effects of the utility model：
The utility model creatively will be changed to disposable extrusion forming by pultrude process twice, have simple in structure, production
Efficient advantage.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the utility model.
Fig. 2 is the schematic cross-sectional view of Fig. 1.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figs. 1-2.
A kind of high and middle pressure valve valve body disposal molding mold, it is mainly made of upper mold 1, lower die 2 and plug 3, such as Fig. 1
Shown, plug 3 is installed in the valve rod mounting hole of valve body 4 deformed damaged when preventing valve body compression molding；1 He of upper mold
The cavity of lower die 2 and the shape at 4 both ends of valve body match；The upper mold of determining valve body upper port size is installed in upper mold 1 simultaneously
Mold core 5, lower die 2 are also equipped with the lower die mold core 6 of determining valve body lower end mouth size.As shown in Fig. 2, when it is implemented, upper mold 1 most
Cr12MoV, quenching hardness HRC58 are used well；Upper mould core 5 uses Cr12MoV, quenching hardness HRC53.Lower die 2 uses
Cr12MoV, quenching hardness HRC60, lower die mold core 6 use Cr12MoV, quenching hardness HRC63.Plug 3 uses
Cr12MoV, quenching hardness HRC63, the stress to prevent in pressing process position with pores among valve body and deform.
Envoy ajusts valve body, the upper top workpiece of upper mold compacting, work in use, only need to valve body blank be put into lower mould
Part is pressed into lower die.Workpiece both ends while necking forming.
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.
