Detailed description of the invention
Fig. 1 is the structural schematic diagram of preform mould provided by the utility model.
Specific embodiment
The utility model provides a kind of preform mould, to keep the purpose of this utility model, technical solution and effect more clear
Chu defines, and the utility model is further described as follows in conjunction with drawings and embodiments.It should be appreciated that described herein
Specific embodiment only explaining the utility model, be not used to limit the utility model.
Referring to Fig. 1, the utility model provides a kind of preform mould, including the die cavity 3 of mold core 2, two of cover half 1, two；Mould
Core 2 and 3 shape forming cavity 4 of die cavity, wherein further include the U-iron 5 for being wrapped hot-wire coil；Cover half 1 is in cross, cover half 1
It is internally provided with T-shaped material channel 11, the flowing of material channel 11 has bottle embryo raw material fluid, the feed inlet of material channel 11
Set on the top of cover half 1, bottle embryo raw material are injected from top to down；Two die cavitys 3 are respectively arranged on the left part of cover half 1, right part side,
Die cavity 3 is equipped with the feed opening 31 that communicates with type chamber 4, and 3 front end of die cavity is equipped with connector 33 with groove, the left part of groove and cover half 1,
Right part matches, and connector 33 is sheathed on the left part of cover half 1, right part respectively and connects so that feed opening 31 and 11 phase of material channel
It is logical, so that bottle embryo raw material flow into type chamber 4 from material channel 11；Die cavity 3 offers appearance in the top side of feed opening 31 or bottom side
Receive slot 32, holding tank 32 is equipped with spring 6 and the iron block 7 set on 6 top of spring, iron block 7 act in spring and block feed opening 31；
The setting corresponding with two iron blocks 7 of the both ends of U-iron 5, U-iron 5 is used for magnetic iron block 7 so that iron block 7 overcomes elastic force mobile, into
And feed opening is made to be in unimpeded state.
Further, the front side of connector 33 is equipped with rubber ring 8, is inserted in the left part or right part of cover half 1, rubber ring in connector 33
8 connect with cover half 1.
Further, connector 33 is equipped with sealing ring 9 in groove, is inserted in the left part or right part of cover half 1 in connector 33, seals
Circle 9 connects with the left part of cover half 1 or right part.Rubber ring and sealing ring are made of heat-resisting material such as fluorubber materials, can
The heat for absorbing cover half 1 slightly expands.
Specifically, connector 33 and die cavity 3 are welded to connect.After producing connector and die cavity, spring and iron block are placed in
In holding tank, then by welding manner, so that connector and die cavity are welded to connect, it is non-dismountable.
Specifically, connector 33 is equipped with rubber ring recess and seal groove, and rubber ring 8 is set in rubber ring recess, and sealing ring 9 is set to
In seal groove, rubber ring 8 protrudes rubber ring recess, and sealing ring 9 protrudes seal groove.When connector and cover half are socketed, rubber
Cushion rubber and sealing ring can play the role of shock absorbing, avoid connector and cover half from being damaged because of impact, in turn result in connector
Become larger with the contact surface gap of cover half, material is easier to flow out from gap, wastes more materials.

The interference fit of sealing ring 9 is installed on seal groove, and the protrusion distance of sealing ring 9 is 3 to 8 millimeters.
Specifically, the bottom of iron block 7 is welded in spring 6.Under the resilient support effect of spring 6, iron block 7 closes off charging
Hole 31, material can not be flowed into type chamber 4 by feed opening 31.
Specifically, the cross sectional shape of material channel 11, feed opening 31 cross sectional shape be rectangular, holding tank 32 and iron block
7 be in four prism type.The height of iron block is bigger than the height of feed opening, the horizontal cross section dimension of iron block and coincideing for holding tank, iron block
It can be moved up and down along the inner wall of holding tank, in this way, material can not flow into holding tank when iron block blocks feed opening.
In conclusion the utility model provides a kind of preform mould, devised at left and right sides of cover half two die cavitys,
Mold core, cover half are internally provided with T-shaped material channel, and the U-joint of two die cavitys is inserted in the left part of cover half, right part respectively,
So that feed opening is communicated with material channel, by injecting bottle embryo raw material fluid toward the feed inlet at the top of cover half, the same time is complete
At two bottle embryo products, output is greatly improved.
The top side of feed opening or bottom side are provided with holding tank, spring and iron block are set in holding tank, in hot-wire coil
In cold situation, iron block intercepts feed opening under the resilient support of spring, prevents material from by feed opening entering type intracavitary.
After connector in die cavity is inserted in and connects with cover half, hot-wire coil is powered, and U-iron generates magnetism, generates magnetic force to iron block, so that
Iron block overcomes elastic force effect movement, enables material by material channel to flow into type intracavitary.After material fills up type chamber, it is powered
Coil blackout, iron block set back, and block feed opening, so that bottle embryo product is isolated with material, and then realize bottle embryo production
Product one-pass molding so that the bottle embryo product shape beauty produced is unified, reduces process, saves without the technical purpose of trimming
Human input.
The connector of die cavity is provided with rubber ring in front side, and sealing ring is provided in groove, connects in connector with cover half
Meanwhile rubber ring resistant to high temperature and sealing ring are also abutted against with cover half, rubber ring, sealing ring after the heat by cover half slightly
Expansion, connected with to fill connector with cover half between slight gap, strengthen sealing effect, prevent material from flowing out from gap to make
At flash, play the role of saving material.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement all should belong to appended by the utility model
