Abstract
A kind of curing forming mold of middle line butterfly valve valve seat, including external mold, internal model, upper die and lower die, upper mold core, screw arbor assembly, internal model and external mold are placed in lower die, and it is fixedly connected by screw arbor assembly, upper mold core is placed on inner membrance, and die cavity, the upper surface installation charging part of upper mold core and external mold are formed between external mold and inner membrance and upper mold core, the part that charges is interior to install material extrusion part, and material extrusion part is pressed by press machine.The beneficial effects of the utility model are: 1, it is artificial sizing material refine need to be only put into the part that charges, by press machine sizing material press-in die type chamber, reduce labor intensity；2, mold cavity can be filled up, the valve seat of extrusion will not generate defect since sizing material is insufficient together sizing material press-in die by charging part, binder part and press machine；3, valve seat high yield rate, saving raw material reduces cost.
Description
Technical field
The utility model relates to a kind of molds, the in particular to curing forming mold of valve seat.
Background technique
Currently, the valve seat curing forming mold of middle line butterfly valve, mainly by external mold, internal model, upper die and lower die and screw rod group
The main parts sizes such as part composition.When mold assembles preparation vulcanization valve seat, first have to rubber raw materials are made the flat of fritter
Shape is finally placed on vulcanizing press again and vulcanizes then by being put into the type chamber of mold by hand.Since rubber raw materials are to pass through
It is put into the type chamber of mold by hand, so rubber raw materials can not completely fill out mold cavity, the valve seat after leading to vulcanization is had
Defect is generated because sizing material is insufficient, so that the qualification rate of valve seat disposal molding reduces, is increased manufacturing cost.
Summary of the invention
To overcome existing curing forming mold drawbacks described above, the utility model provides high yield rate, without artificial blowing
Curing forming mold.
The utility model solves its technical problem the technical solution adopted is that a kind of middle line butterfly valve valve seat is sulfided into
Pattern tool, including external mold, internal model, upper die and lower die, upper mold core, screw arbor assembly, internal model and external mold are placed in lower die, and are passed through
Screw arbor assembly is fixedly connected, and upper mold core is placed on inner membrance, forms die cavity between external mold and inner membrance and upper mold core, upper mold core with
The upper surface installation charging part of external mold, charging part is interior to install material extrusion part, and material extrusion part is pressed by press machine, and the part that charges is by sky
Heart annulus cylinder and Circular Plate composition, hollow ring cylinder are fixed in Circular Plate, and annular U-lag, open circles are offered in Circular Plate
The charging door of ring cylinder is communicated with annular U-lag, annular U-lag and mould cavity；Material extrusion part is by upper ring plate, lower Circular Plate and one
A support frame forms, and installs press machine on upper ring plate, and lower Circular Plate is placed in charging door, passes through press machine and presses upper annulus
Sizing material in charging door is squeezed into die cavity by plate, and upper mold is mounted on upper mold after removing charging part, material extrusion part and press machine
On the upper surface of core and external mold.
The beneficial effects of the utility model are: 1, it is artificial sizing material refine need to be only put into the part that charges, pass through press machine
Sizing material press-in die type chamber, labor intensity is reduced；2, sizing material is pressed into together by charging part, binder part and press machine by mould
Tool, can fill up mold cavity, and the valve seat of extrusion will not generate defect since sizing material is insufficient；3, valve seat high yield rate is saved
Raw material reduces cost.

Specific embodiment
As shown in Figure 1, 2, a kind of curing forming mold of middle line butterfly valve valve seat, including external mold 14, internal model 13, upper mold
17, lower die 15, upper mold core 11, screw arbor assembly 16, internal model 13 and external mold 14 are placed in lower die 15, and solid by screw arbor assembly 16
Fixed connection, upper mold core 11 are placed on inner membrance 13, and die cavity 12, upper mold core are formed between external mold 14 and inner membrance 13 and upper mold core 11
11 with the upper surface of external mold 14 installation charging part 9, material extrusion part 10 is installed in charging part 9, material extrusion part 9 is applied by press machine 1
Pressure, charging part 10 are made of hollow ring cylinder 6 and Circular Plate 7, and hollow ring cylinder 6 is fixed in Circular Plate 7, is opened in Circular Plate 7
Equipped with annular U-lag 8, the charging door 4 of hollow ring cylinder 6 is communicated with annular U-lag 8, and annular U-lag 8 is communicated with die cavity 12；It squeezes
Materials and parts 10 are made of upper ring plate 2, lower Circular Plate 5 and a support frame 3, and press machine 1, lower Circular Plate 5 are installed on upper ring plate 2
It is placed in charging door 4, upper ring plate 2 is pressed by press machine 1, the sizing material in charging door 4 is squeezed into die cavity 12, work as glue
After material enters die cavity 12, charging part 9, material extrusion part 10 and press machine 1 are removed, upper mold 17 is mounted on upper mold core 11 and external mold
On 14 upper surface, finally the mold of charged is vulcanized on being put into vulcanizer.
