Description

The sulfurizing mould of plough groove type pipe joint seal ring

Technical field

The utility model relates to technical field of vulcanized, relates in particular to a kind of sulfurizing mould that is used for plough groove type pipe joint seal ring.

Background technology

Now water supply pipe, gas piping and fire protection pipeline usually adopt plough groove type pipe joint to connect, and its method is the joint that sealing ring is set in two pipes, then with pipe collar with its banding.Because this method need not the machining screw at the pipe joint place, connect fast and good sealing effect, thereby obtained using widely in the pipeline installing area.

Plough groove type pipe joint seal ring processes by sulfuration process with mould on vulcanizer, known sulfurizing mould comprises the upper die body that is positioned at outer upper, be arranged in the die body of outer middle side part, be positioned at the lower mold body of outer lower portion, and being positioned at inboard core block, the corresponding binding face of described upper die body, middle die body, lower mold body and core block is fitted and is formed the plough groove type pipe joint seal ring die cavity of sealing.Technical process is as follows: the first step is charging, and middle die body and lower mold body are merged, and then the raw material bar is wrapped in the sealing ring die cavity, puts core block, puts upper die body again, pushes in the vulcanizer heating plate with the handgrip mould; Second step was a matched moulds, and heating plate moves upward at the drive lower edge of hydraulic cylinder guide rail, until with the corresponding binding face pressing of upper die body; The 3rd step was sulfuration, by electric heating body sulfurizing mould heated, and the insulation certain hour; The 4th step was die sinking, and heating plate moves downward at the drive lower edge of hydraulic cylinder guide rail, made heating plate and following heating plate leave certain unlatching distance up and down; The 5th step was discharging, at first mould was taken out together, then upper and lower die body was separated with sealing ring after the moulding, and therefrom die body takes out sealing ring and core block, at last sealing ring is taken out from core block.By above-mentioned processing step as can be seen, this split type sulfurizing mould is more loaded down with trivial details when charging and discharging, and the process time is longer, also hinders the workman easily, thereby has reduced operating efficiency, has increased heat energy loss.

Summary of the invention

Technical problem to be solved in the utility model is: the sulfurizing mould that a kind of plough groove type pipe joint seal ring is provided, process time expend long technical problem to solve when charging and the discharging, this mould structure is simple, and is easy to use, improve the operating efficiency of vulcanizer, reduced heat energy loss.

For solving the problems of the technologies described above, the technical solution of the utility model is: the sulfurizing mould of plough groove type pipe joint seal ring, comprise the upper die body that is positioned at outer upper, be arranged in the die body of outer middle side part, be positioned at the lower mold body of outer lower portion, and be positioned at inboard core block, and the corresponding binding face of described upper die body, middle die body, lower mold body and core block is fitted and is formed the plough groove type pipe joint seal ring die cavity of sealing, and described lower mold body is made as one with middle die body or fixedlys connected; Described upper die body is provided with axially directed portion, and core block can be sheathed on described axially directed portion with moving axially; It also comprise be arranged between described upper die body and the core block, when the corresponding binding face axial separation of upper die body and core block to the sealing ring after the moulding can be taken out apart from the time, prevent the anti-drop device that both throw off its, and both keep the positioner of fit-state can to make it when the corresponding binding face applying of upper die body and core block.

As a kind of specific embodiment, described anti-drop device comprises the locking member of the axially directed portion that is installed on described core block, and described locking member has the limiting section of the outer peripheral face that extends radially out described axially directed portion; Described core block is provided with a spacing hole greater than the pilot hole of core block, and the outer peripheral face of the axially directed portion of described upper die body and the spacing hole of described core block form limit chamber; The limiting section of described locking member stretches in the described limit chamber.

As a kind of specific embodiment, described positioner comprises the annular groove of the spacing hole inner peripheral surface that is arranged at described axially directed portion, and described annular groove is corresponding with respect to the maximum axial separating distance of core block to the axial distance and the upper die body of the shoulder of limit chamber; The limiting section of described locking member has and the suitable head of described annular groove shaped; The axially directed portion of described upper die body is provided with radial hole, and described locking member is movably installed in described radial hole; Described positioner also comprises the spring that is installed in the described radial hole, with the adjustment screw that is connected with the end thread of described radial hole.

After having adopted technique scheme, the beneficial effects of the utility model are: because described lower mold body is made as one with middle die body or fixedlys connected; So when charging and discharging, need not die body in the mounting or dismounting; Because described upper die body is provided with axially directed portion, core block can be sheathed on described axially directed portion with moving axially; It also comprise be arranged between described upper die body and the core block, when the corresponding binding face axial separation of upper die body and core block to the sealing ring after the moulding can be taken out apart from the time, prevent the anti-drop device that both throw off its, and both keep the positioner of fit-state can to make it when the corresponding binding face of upper die body and core block is fitted, therefore, when filling with substance, only need to promote core block, the head of the limiting section of limit body is snapped in the annular groove, and the elastic force of spring can make it both kept the clamping state this moment; During discharging, by applying extra axial opening force, make the head of the limiting section of limit body break away from clamping with annular groove, and upper die body and core block are relatively moved leave certain distance, the limiting section of limit body will slide to the shoulder of limit chamber and block at this moment, both can not throw off connection thereby make it, the sealing ring after the moulding are taken off from core block to get final product then.This sulfurizing mould is simple in structure easy to use, has saved the time of charging and discharging, thereby has improved the operating efficiency of vulcanizer, has reduced heat energy loss.The utility model can also pass through the turn-knob adjustment screw, comes the reduction length of regulating spring, and then regulates the size of the elastic force that makes upper die body and core block maintenance clamping state, makes this mould be more convenient for using.
