Description
Technical field
The utility model is related to extrusion plastic technical field of mold, and in particular to one kind is used for two kinds of raw material fusing point temperature difference phases
Co-extruding mould in the very big high/low temperature mould of difference.
Background technology
The temperature of injection mould is for the filling flow of plastic molting, solidifying and setting, the shape of production efficiency and product and
Dimensional accuracy all has a major impact.And appropriate uniform mold temperature must be controlled by the humidity control system in mould.Nothing
Which kind of it is injection moulded by plastics, there are one more suitable mould temperature scopes, within this range, the flowing of plastic melt
Property is good, and easily full of die cavity, article removal after-contraction and buckling deformation are small, the dimensionally stable of shape, physical and mechanical property and
Surface quality is also higher, and still, if without humidity control system, mould temperature is difficult to control in rational scope, plastics
Problem may occur for the quality of item after the filling flow of melt and the demoulding.
During cooling and shaping of the plastic melt after the mold filling of its filling flow, due to the influence of product geometry,
The temperature of die cavity table wall everywhere is difficult uniformity, therefore, the cooling velocity of product everywhere will difference, so as to cause system
Product shrink uneven and generate a degree of stress, this has undesirable influence to the Forming Quality of product.
At present, the mode for being typically employed in mould inside installation heating tube on the market heats mold, due to heating
Pipe usually has longer cold end at both ends, and the temperature of die cavity table wall everywhere is difficult uniformity, and long-time service is susceptible to short circuit
Or the problem of open circuit.Moreover, in the bigger raw material co-extruding mould of two kinds of temperature difference, if the temperature difference of two kinds of raw materials is 80
More than degree, using the mode of heating tube heating, the mould temperature for causing mold is difficult to control in rational scope, influences the life of product
Yield and quality.
Utility model content
The purpose of this utility model is to provide co-extruding mould in a kind of high/low temperature mould, and oil can be made fully to be obtained in mold
Xun Huan, makes the die temperance control of mold in rational scope.
Technical solution is used by the utility model solves its technical problem：Co-extruding mould in a kind of high/low temperature mould, bag
Upper mold, middle mould and lower die are included, first charging aperture is equipped between upper mold and middle mould, second charging aperture is equipped between middle mould and lower die,
It is characterized in that：The first die cavity is formed between the upper mold and middle mould, forms the second die cavity between middle mould and lower die, described
The one side or both sides of one die cavity and the second die cavity are respectively provided with the oil channel structures heated to raw material in die cavity, described
Oil channel structures include through mold upper oil cavitie and lower oil cavitie, if between upper oil cavitie and lower oil cavitie side by side connection be equipped with drier oil
Road is equipped with a plug between adjacent two oil duct, and the plug is staggered in upper oil cavitie and lower oil cavitie successively.
As preference, the plug is fixed on by plug bar in upper oil cavitie and lower oil cavitie respectively.
Further, the plug is arranged with sealing ring.
The beneficial effects of the utility model are：It is simple in structure, oil can be made fully to be cycled in mold, make mold
Die temperance control is in rational scope, so that the quality of product is protected.

Specific embodiment
The technical issues of in order to solve the utility model, technical solution and advantageous effect are more clearly understood, below
With reference to attached drawing and embodiment, the utility model is further described.
As shown in Figs 1-4, co-extruding mould in a kind of high/low temperature mould of the utility model, including upper mold 1, middle mould 2 and lower die 3,
First charging aperture 4 is equipped between upper mold 1 and middle mould 2, second charging aperture 5, upper mold 1 and middle mould 2 are equipped between middle mould 2 and lower die 3
Between form the first die cavity, the one side or two of the second die cavity, the first die cavity and the second die cavity is formed between middle mould 2 and lower die 3
Side is respectively provided with the oil channel structures heated to raw material in die cavity, and oil channel structures include 6 He of upper oil cavitie through mold
Lower oil cavitie 7, connection is equipped with several oil ducts 8 side by side between upper oil cavitie 6 and lower oil cavitie 7, and a plug is equipped between adjacent two oil duct 8
9, and plug 9 is staggered successively in upper oil cavitie 6 and lower oil cavitie 7, is allowed to be formed the oil circuit of a S-shaped.
Plug 9 is fixed on by plug bar 10 in upper oil cavitie 6 and lower oil cavitie 7 respectively；See Fig. 5, in order to increase sealing effect,
Groove is had at the both ends of plug 9, is then cased with sealing ring 11 respectively in groove.
During use, one end of 7 any one oil pocket of upper oil cavitie 6 or lower oil cavitie is selected as oil inlet, and by stifled
First 14 block the port of this another oil pocket of end, and as shown in Figure 3-4, the present embodiment is using one end of upper oil cavitie 6 as oil inlet
12, the port at 7 this end of lower oil cavitie is blocked by plug 14, and the heated oil of die heater is entered by oil inlet 12 in upper oil cavitie 6,
Since plug 9 is staggered successively in upper oil cavitie 6 and lower oil cavitie 7, the oil in upper oil cavitie 6 enters lower oil cavitie 7 by oil duct 8,
Upper oil cavitie 6 is entered by oil duct 8 again, ultimately forms the oil circuit of a S-shaped, by plug 14 by the other end mouth of upper oil cavitie 6
It blocks, the oil in oil pocket flows back to die heater forming circuit by oil outlet 13, the i.e. other end of lower oil cavitie 7.
During work, oil transportation is distinguished to each oil channel structures by die heater, and the oil temperature in each oil circuit is according to two kinds of raw material institutes
Need temperature that control is adjusted, when respectively reaching the required temperature of each raw material, two kinds of raw materials arrive mould after spiro rod plasticizing
The feed inlet of tool, a kind of raw material enter the first die cavity from first charging aperture 4, and another raw material enters second from second charging aperture 5
Die cavity.Two die heaters control the temperature of two kinds of big raw materials of two kinds of high-low temperature differences by the oil channel structures of mold respectively.By
The actual temperature that the temperature of on-the-spot test is fed back really.The temperature difference differs greatly, and field control temperature is very stable, has reached mold life
Production is stablized.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Any modification, equivalent replacement and improvement made within new spirit and principle etc., should all fall the protection in the utility model
Within the scope of.
