A kind of plastic electrofusion saddle mold
Technical field
The utility model belongs to electric smelting saddle type technical field of mold, is related to a kind of plastic electrofusion saddle mold.
Background technique
Plastic electrofusion saddle pipe fitting after moulding, since its underpart package power is larger, and is wound on the inner wall of pipe fitting
Resistance wire, and it to be provided with copper bolt in plastics capacitor pipe fitting domestic demand, in process of production, usually copper bolt is directly arranged
In type in-core, and due to being provided with resistance wire, after causing entire mold needs to be cooled to, then type core and workpiece be placed on pumping
Core pulling is carried out on core machine.
It therefore, is that operator is needed to carry out mould inside, and by the workpiece of injection molding, type in existing mold
Core frame and type core take out together, and operation is more troublesome, and in workpiece shaping, are only merely to need one section of copper bolt to be arranged
In workpiece, and another section is to need to cut, and the discarded section of copper bolt is discharged, but in the actual production process, due to
During die sinking, just copper bolt is broken disconnected, therefore in the process of die sinking, the discarded section of copper bolt is located in mold,
It results in staff and is difficult to the case where clearing up appearance, and existing mold is caused using artificial modulus and molding workpiece
The production efficiency of entire mold reduces.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of plastic electrofusion saddle mould
Tool, technical problem to be solved in the utility model is how to improve the production efficiency of plastic electrofusion saddle mold.
The purpose of this utility model can be realized by the following technical scheme:
A kind of plastic electrofusion saddle mold, including cover half block and dynamic model block, are formed between the cover half block and dynamic model block
Forming cavity for shaping workpiece, which is characterized in that guide rail and guide rail core are equipped between the dynamic model block and cover half block, it is described to lead
The ejection hole being connected with forming cavity is offered in the middle part of rail core, the guide rail is equipped with the tapered wedges one and inclined wedge mutually agreed with
Block two, the tapered wedges two are fixed on one end of guide rail, and the tapered wedges one are arranged on the other end and tapered wedges one of guide rail
The mandril in ejection hole is embedded in equipped with end, the side of the guide rail is equipped with the driving that guide rail can be driven to move back and forth along its length
Part, guide rail can be driven mobile for the actuator so that tapered wedges one are ejected and tapered wedges one is made to pass through mandril for work by tapered wedges two
Part ejection, the guide rail in-core are additionally provided with the return unit that can be pushed into tapered wedges one in guide rail.
Working principle: workpiece injection molding in forming cavity, the end of the mandril of tapered wedges one is to be located at ejection hole at this time
It is not pierced by ejection hole inside, after workpiece shaping, the side of guide rail is arranged in cover half block and the die sinking of dynamic model block, actuator, and
Actuator is connect with guide rail core, and driving actuator is able to achieve guide rail and drives tapered wedges two mobile towards tapered wedges one, when being moved to
Tapered wedges one are ejected, the mandril on tapered wedges one is with the movement of tapered wedges one at this time, since ejection hole is connected to forming cavity, because
One end ejection ejection Kong Bingneng of this mandril ejects the workpiece in forming cavity, does not need staff and enters directly into cover half
Workpiece is taken out between block and dynamic model block, but is directly ejected by mandril, and by driving actuator to make tapered wedges
One and tapered wedges two are not in stuck phenomenon, to realize the fast demoulding to workpiece, improve the production effect of mold
Rate;When needing to be molded next time, as long as driving actuator resets tapered wedges two, tapered wedges one are in return unit at this time
It under effect, can reset in guide rail again, and then facilitate the molding of mold next time, further improve the production effect of mold
Rate.
In above-mentioned plastic electrofusion saddle mold, the tapered wedges one have inclined-plane one close to one end of tapered wedges two,
The tapered wedges two have inclined-plane two close to one end of tapered wedges one, and mobile tapered wedges two can make the inclined-plane one and inclined-plane two-phase
Fitting.
During tapered wedges two eject tapered wedges one, the inclined-plane two-phase on the inclined-plane one and tapered wedges two of tapered wedges one
Fitting, then the inclined-plane one of tapered wedges one progressively disengages to tapered wedges two with the inclined-plane two of tapered wedges two and can push up tapered wedges one
Out, so that the stability in whole process gets a promotion, the production efficiency and stability of mold are further improved.

It is connected to sliding groove, the guide rail is equipped with the chip removal mouth being discharged for copper bolt.
The other end of copper bolt is pierced by forming cavity and is arranged in mounting hole, and copper bolt is equipped with can be with guide rail core lateral wall
The shoulder block to lean, in mold clamping, copper bolt is to be set in mounting hole, and the other end of copper bolt is to have set
It sets in forming cavity, in forming process, which is to be located in molding workpiece, and only this part is by workpiece
It needs to be arranged in the corresponding position of workpiece, therefore during demoulding, needs for copper bolt to be truncated, and since copper bolt is logical
Shoulder block is crossed to be fixed on guide rail core, during demoulding, while tapered wedges one being ejected by tapered wedges two, at
The workpiece and guide rail core of type are detached from, and copper bolt can be truncated at this time, and the copper bolt being truncated can fall to sliding out of chip-removal hole
On slot, and copper bolt is discharged by mold out of chip removal mouth by the reset of tapered wedges one and tapered wedges two, realizes mold oneself
Dynamic waste discharge material, further improves the production efficiency of mold.
In above-mentioned plastic electrofusion saddle mold, the guide rail core is equipped with rail core fixture block, and the guide rail, which is equipped with, to be slided
Slot and the baffle that can be leant with rail core fixture block, the rail core fixture block are equipped with sliding part, and the chip removal mouth is provided on guide rail
And vertically running through guide rail, the rail core fixture block can be slidably connected on the chute and in guide rail by sliding part and sliding and can will be broken
The copper bolt split is pushed to chip removal mouth.
During actuator driving, rail core fixture block moves together with guide rail core, during the sliding of guide rail core, energy
The copper bolt of truncation being located on guide rail is moved to chip removal mouth with dynamic rail core fixture block, and can be discharged from chip removal mouth, is realized pair
The cleaning of waste material on guide rail, so that chip removal is more convenient, and during sliding, track is more smooth, to improve mould
The production efficiency of tool.
In above-mentioned plastic electrofusion saddle mold, the aperture of the chip-removal hole is greater than the aperture of mounting hole.
