Abstract
The invention discloses a water immersion full-sealing negative pressure shaping system of an extrusion mold, which is provided with a sealed box body, the box body is internally provided with a mold cavity component, supporting frames are arranged in the positions of box boards at the two ends of the box body, the mold cavity component is arranged between the two supporting frames by a four-corner squeeze pad, the mold cavity component inside the box body is provided with a plurality of narrow grooves which are vertical to the motion direction of a profile, the narrow grooves surrounds the whole circle of the mold cavity, the mold cavity component is completely immersed into cooling medium in the box body, vacuum negative pressure is formed in the box body by a fluid drawing pipe and a vacuum pumping duct, and the vacuum negative pressure shapes an extruded product via the narrow grooves on the mold cavity component. The mold cavity component consists of a plurality of shaping boards. The system shapes the plastic profile accurately in the immersion full-sealing negative pressure mode, thus avoiding the influence of vacuum fluctuation on profile shaping in the condition of improving the cooling efficiency and achieving the aim of improving the production efficiency and quality of the product; and the cooling medium is in direct contact with a plastic parison, thus improving the cooling efficiency.
Description
Technical field
The present invention relates to a kind of water immersion full-sealing negative pressure shaping system of plastic material extrusioning shaping technology, particularly a kind of extrusion die.
Background technology
Dry type stock mould and the moulding of negative pressure of vacuum water tank that traditional plastic material extrusion die adopts complete aqueous vapor to separate.The mold cavity surface of dry type stock mould is processed with special vacuum air drain, make the plastic parison that from die head, reaches molten condition be close to mold cavity surface through heating, cooling water is flowing in the special passage of die cavity, carry out heat exchange by metal mold cavity, to reach the purpose of cooling plastic section bar, therefore the Vacuum shaping effect of this dry type stock mould is better, and cooling effectiveness is because be subjected to the influence of metal heat transfer coefficient magnitude.The negative pressure of vacuum water tank has preferably cooling effectiveness and the effect of finalizing the design is relatively poor, and the influence that is subjected to the negative pressure of vacuum fluctuation is bigger, and has influence on the precise forming of section bar, thereby influences the quality of product.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, a kind of water immersion full-sealing negative pressure shaping system of extrusion die has been proposed, this system accurately finalizes the design to plastic material by the water immersion full-sealing negative pressure mode, under the situation that improves cooling effectiveness, avoid the influence of the fluctuation of vacuum, reach the purpose that improves production efficient and quality for product moulding.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of water immersion full-sealing negative pressure shaping system of extrusion die, be characterized in: be provided with a seal case, in casing, be provided with mold cavity component, the charging aperture of mold cavity component and discharging opening are arranged on the tank ends boxboard, the place is provided with bracing frame at the tank ends boxboard, mold cavity component is contained between two bracing frames by four jiaos strap, the mold cavity component that is located at box house is provided with some narrow grooves perpendicular to the section bar direction of motion, described narrow groove is around whole one week of die cavity, casing is provided with cooling medium inlet and outlet, casing is provided with duct and the liquid suction pipe that is used to vacuumize, casing is provided with and is used to regulate the valve of casing vacuum size and the vacuum meter that is used for the monitoring vacuum size, the complete submergence mold cavity component of cooling medium in casing, casing is by liquid suction pipe and vacuumize duct formation negative pressure of vacuum, and negative pressure of vacuum is finalized the design to extruded product by the narrow groove on the mold cavity component.
The technical problem to be solved in the present invention can also come by the following technical programs to realize that further mold cavity component is made of several stereotype plates that described narrow groove is arranged between the adjacent stereotype plate.
The technical problem to be solved in the present invention can also come to realize that further described narrow well width is 0.8～1.2mm by the following technical programs.
The present invention compared with prior art, this system accurately finalizes the design to plastic material by the water immersion full-sealing negative pressure mode, under the situation that improves cooling effectiveness, avoid the influence of the fluctuation of vacuum, reach the purpose that improves production efficient and quality for product moulding; Cooling medium directly contacts with the plastic parison that reaches molten condition from die head through heating, has improved cooling effectiveness, thereby can enhance productivity.

The specific embodiment
A kind of water immersion full-sealing negative pressure shaping system of extrusion die, be provided with a casing 2 with better sealing effectiveness, casing is formed the casing that seals by left plate, right plate, loam cake, base plate, and bottom half is provided with the footing piece that connects with equipment and is used for casing is fixed on equipment.
In casing 2, be provided with mold cavity component 5, the charging aperture of mold cavity component 5 and discharging opening are arranged on the tank ends boxboard, the place is provided with bracing frame 4 at the tank ends boxboard, mold cavity component 5 is contained between two bracing frames 4 by four jiaos strap 3, the mold cavity component that is located at box house is provided with some narrow grooves 11 perpendicular to the section bar direction of motion, described narrow groove 11 is around whole one week of die cavity, and described narrow well width is 0.8～1.2mm.
Casing is provided with the extraneous duct that communicates and is used for cooling system on the connection device so that the entering and flow out of cooling medium, casing is provided with the duct 10 that is used to vacuumize simultaneously, be used for the vacuum system on the connection device, simultaneously casing is provided with and is used to the vacuum meter 8 regulating the valve 9 of casing vacuum size and be used for the monitoring vacuum size.The complete submergence mold cavity component of cooling medium in casing, casing is by liquid suction pipe 7 and vacuumize duct 10 formation negative pressure of vacuum, and negative pressure of vacuum is finalized the design by narrow groove 11 extruded products on the mold cavity component 5.The vacuum that vacuum meter 8, valve 9 are used to monitor and regulate casing is with stablizing with controlled of vacuum in the assurance casing.
Aforesaid mold cavity component 5 need be passed through polishing with the surface that the plastic parison that reaches molten condition from die head through heating contacts, and reaches mirror effect, to guarantee the surface quality of final shape product.
Cooling medium is by being installed in water pipe head 6,1 on left plate, the right plate, entering the cooling extruded goods of casing, by liquid suction pipe 7 cooling water is forced to extract out casing and quicken cooling medium flowing in casing, form the negative pressure of vacuum of casing simultaneously to strengthen cooling effect.The mold cavity component profile becomes similar figures with extruded product, to reduce cooling medium and extruded product contact distance, as required, strap 3 can be to closely cooperate with mold cavity component 5, it also can be matched in clearance, during matched in clearance, a plurality of stereotype plates in the mold cavity component have self-align and suffer from one's own actions RC effect.
