Description

Heat insulation strip extrusion die
Technical field
The present invention relates to heat insulating strip technical field, particularly a kind of heat insulation strip extrusion die.
Background technology
At present, in use, raw material, in the feed cavity between mouth mould charging aperture inflow entrance mould and core rod, and enters stock mould and by discharging opening moulding discharging along stock mould charging aperture to heat insulation strip extrusion die.In said process, stock mould inner chamber cannot be cooling, and the high temperature in forming process causes product cavity crude, affects properties of product.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiencies in the prior art, provides a kind of heat insulation strip extrusion die, avoids to reach the object that in forming process, stock mould high temperature causes the crude problem of product cavity to occur.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of heat insulation strip extrusion die, comprise a mouthful mould, core rod, stock mould, one end that described stock mould is connected with core rod is provided with boss, the other end end face of described stock mould is provided with discharging opening, described raised head face is provided with charging aperture, described charging aperture is connected with described discharging opening and forms sizing chamber, described core rod comprises plug, transverse arm, be connected to the fixed arm at transverse arm two ends, described plug bottom is connected to described transverse arm middle part, described core rod is provided with and runs through its inner pure water coolant flow channel, in described boss, be provided with the groove passing for transverse arm, between the inwall of described groove and the outer wall of transverse arm, be provided with gap.
One of them fixed arm is provided with water inlet, another fixed arm is provided with delivery port, and described pure water coolant flow channel is run through the fixed arm at fixed arm, transverse arm one end, plug, the transverse arm other end, delivery port place at water inlet place successively to delivery port by water inlet.
Two madial walls of described groove are skew wall.
On described stock mould, be extended with holder, described holder is provided with groove, and described fixed arm is provided with groove and matches and merge the projection being connected in groove.
The present invention adopts said structure, has the following advantages: 1, avoid stock mould high temperature in forming process to cause the crude problem of product cavity to occur, improve product cavity smoothness, enhance product performance; 2, the holder clamping of the fixed arm of core rod and stock mould, is connected firmly, simultaneously easy accessibility; 3, because the transverse arm of core rod is less, coolant flow channel is smaller, after use pure water, avoids the calcium ions and magnesium ions in water that coolant flow channel is stopped up; 4, can serialization produce.

Detailed description of the invention
A kind of heat insulation strip extrusion die as shown in Figure 1 to 4, comprise mouthful mould 1, core rod 2, stock mould 3, one end that stock mould 3 is connected with core rod 2 is provided with boss 4, and the other end end face of stock mould 3 is provided with discharging opening 5, and boss 4 end faces are provided with charging aperture 6, charging aperture 6 is connected with discharging opening 5 and forms sizing chamber, sizing is provided with sizing core rod in chamber, is formed into die cavity, when heat insulating strip moulding between sizing core rod and sizing cavity wall, its shape is by forming cavity moulding, and heat insulating strip inner chamber is by the core rod moulding of shaping.Core rod 2 comprises plug 7, transverse arm 8, is connected to the fixed arm 9 at transverse arm 8 two ends, plug 7 bottoms are connected to transverse arm 8 middle parts, core rod 2 is provided with and runs through its inner pure water coolant flow channel, is provided with the groove 10 passing for transverse arm 8 in boss 4, between the inwall of groove 10 and the outer wall of transverse arm 8, is provided with gap.
One of them fixed arm 9 is provided with water inlet, another fixed arm 9 is provided with delivery port, and pure water coolant flow channel is run through the fixed arm at fixed arm, transverse arm one end, plug, the transverse arm other end, delivery port place at water inlet place successively to delivery port by water inlet.Two madial walls of groove 10 are skew wall.On stock mould 3, be extended with holder 11, holder 11 is provided with groove, and fixed arm is provided with groove and matches and merge the projection 12 being connected in groove.The holder clamping of the fixed arm of core rod and stock mould, is connected firmly, simultaneously easy accessibility.
This mould is in when work, and raw material enters from the charging aperture of mouth mould 1, enters stock mould moulding in its forming cavity, discharging by the feed cavity between mouth mould 1 and core rod 2 to stock mould charging aperture.In forming process, logical pure water in pure water coolant flow channel, pure water flows through from transverse arm 8, reduce the temperature in groove 10, stock mould 3 is carried out cooling, avoid stock mould 3 high temperature in forming process to cause the crude problem of product cavity to occur, improve product cavity smoothness, enhance product performance.Two madial walls of groove 10 are skew wall, contribute to heat radiation.Because the transverse arm of core rod is less, coolant flow channel is smaller, after use pure water, avoids the calcium ions and magnesium ions in light water that pure water coolant flow channel is stopped up.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted technical scheme of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
