The invention discloses a forming die for a bent connecting pipe. The forming die comprises an upper die, a lower die and mandrels and is characterized in that the mandrels comprise a main pipe mandrel and a branch pipe mandrel, wherein the branch pipe mandrel is inserted into the main pipe mandrel; the branch pipe mandrel can be bent; a main pipe die cavity and a branch pipe die cavity which respectively correspond to the main pipe mandrel and the branch pipe mandrel are arranged on the bonding surface of the upper die and the lower die; in addition, a connecting rubber die cavity is arranged at the intersected position of the main pipe die cavity and the branch pipe die cavity. According to the forming die for the bent connecting pipe, disclosed by the invention, the bent connecting pipe is produced by using the bendable branch pipe mandrel in a shaping manner; after the vulcanization molding is finished, the branch pipe mandrel can be pulled from the bent connecting pipe easily and conveniently, so that the bent connecting pipe can be manufactured into random required size.
Description
Technical field
The present invention relates to sebific duct mould, more particularly, to a kind of bending connection pipe shaping mould.
Background technology
Using tube core whether sebific duct forming method is pressed, and can be divided into and have core method (again including soft core method and hard core method), called non-sleeve method.
Hard core method is to carry out molding using metal or rigid plastics plug, will be enclosed within to be become on plug by extruding the pipe producing
Type.The feature of hard core method is that molding sebific duct internal diameter size is accurate, smooth, and glue-line is good with the adherence strengthening interlayer.But institute's energy
The sebific duct length of molding is shorter, and has difficulties when making bend pipe, and plug is more difficult to be extracted in sebific duct.
In particular cases need for arm to be inserted in supervisor's connection at some, in the company near sebific duct crooked position
Connect difficult forming, because plug cannot be extracted, thus govern the application of many logical connecting lines.Traditional approach is using pipeline even
Fitting many sebific ducts are withheld by collar or clip clamping etc. fixed form be attached, but this kind of mode lead to connect
Easily sealing problem in line connection in sebific duct, easily leaks in line connection in use for some time.
Content of the invention
The technical problem to be solved and the technical assignment proposing are that prior art is improved, and provide one kind
Bending connect pipe shaping mould, solve current technology in sebific duct mould be difficult to make bending connecting tube, plug be difficult from
The problem extracted in the sebific duct of brake forming.
For solving above technical problem, the technical scheme is that
A kind of bending connects pipe shaping mould, including upper die and lower die and plug it is characterised in that described plug includes
Supervisor's plug and core rod, a core rod is inserted in supervisor's plug, and a core rod is flexible, the connecing of upper die and lower die
Supervisor's die cavity corresponding to supervisor's plug and a core rod is provided with conjunction face, props up tubular cavity, and in supervisor's die cavity and arm
The position that die cavity intersects offers connection rubber die cavity.
Bending of the present invention connects pipe shaping mould and is used for making the how logical connection rubber tube of bending, due to a core rod
Flexible, then the pipe extruding production is enclosed within a core rod, can deform with arm mandrel bend, by arm mandrel bend extremely
After the shape of a tubular cavity in upper die and lower die, it is put in a tubular cavity, then carries out sulfur by after upper die and lower die matched moulds
Chemical conversion type, makes the how logical connection rubber tube with curved shape, has resilient characteristic using sebific duct, will prop up core rod and recover straight line
State can be extracted propping up core rod, finally gives complete swan-neck.
The present invention will be responsible for the position connection that die cavity is intersected with a tubular cavity using connecting rubber die cavity, is connecting rubber-type
Intracavity injects sizing material, will be responsible for and arm parcel connects, sulfidization molding makes supervisor and arm form integral type, thus need not make
Connect associate member with three way cock, clip or enhancing skeleton etc., make and connect overall integral type three-way rubber pipe, effectively improve curved
The sealing of bent connecting tube.Bending of the present invention connects pipe shaping mould and only need to be responsible for and arm two, opens on supervisor
Hole, arm is inserted in the perforate of supervisor by a core rod, is connecting the injection rubber vulcanization molding of rubber-type intracavity, is being formed close
The good connection member of envelope property, it is ensured that the supervisor of three-way rubber pipe and arm junction will not leak, effectively extends and uses the longevity
Life.
Further, a described core rod is constituted by front bar and rear bar are hinged, realizes Zhi Guanxin by way of hinged
Rod can 360 ° of bendings, according to actual flexion connecting tube actual demand bending arbitrarily angled so that the strong applicability of core rod, front
Bar is plugged on supervisor's plug.
Further, described front bar end is provided with screw thread, using screw thread so that a core rod is connected with supervisor's plug
Firmly, and ensure size precisely, the installation and removal of a core rod are all convenient and swift, improve working (machining) efficiency.
Further, described connection rubber-type intracavity is provided with injection pressure mouth, by the way of the injection moulding upper mould, under
To connecting rubber-type intracavity injection sizing material under mould closure state, make entirely to connect rubber die cavity full of sizing material, after sulfidization molding
Form the good connection member of sealing, improve sealing and the service life of bending connecting tube.
Further, described upper die and lower die are additionally provided with location hole and alignment pin.Played by alignment pin and location hole
Connect the effect of guiding and positioning it is ensured that precision during upper die and lower die matched moulds is it is ensured that connect the dimensional accuracy of rubber-moulding,
It is more beneficial for ensureing to be responsible for the structural strength with arm junction and sealing.
Further, described upper die and lower die are provided with handle, using handle can convenient folding upper die and lower die, behaviour
It is more convenient to make.
Further, described supervisor's plug is provided with retainer ring, lower mould is provided with fixed column.The present invention is using solid
Determine ring set be contained in play in fixed column positioning and prevent deviate from effect it is ensured that bending connecting tube accurate to dimension, simultaneously
It is easy to upper die and lower die matched moulds to put in place, it is to avoid make matched moulds difficult because supervisor's plug is placed not in place, impact connects rubber-type
Sealing at chamber, it is to avoid injection moulding is affected.
Compared with prior art, the invention has the advantages that:
Bending of the present invention connects pipe shaping mould and utilizes flexible core rod sizing to make bending connecting tube,
What after the completion of sulfuration sizing, a core rod can be easy and convenient extracts out so that bending connecting tube can make from bending connecting tube
Become the size arbitrarily needing；
Open up connection rubber die cavity in supervisor and arm junction, using connection rubber die cavity in its interior rubber vulcanization
Tight, in supervisor and arm junction, is formed integrally the bending connecting tube of formula, effectively improves sealing and service life afterwards；
