Description

Reduce extravagant improved generation collecting valve of steam

Technical Field

The utility model relates to a foaming shaping field, concretely relates to reduce extravagant improved generation integrated valve of steam.

Background

The foam molding device is equipment for molding thermoplastic foam plastic, a foam molding die comprises a female die core (on a fixed die) and a male die core (on a movable die), the two cores are provided with air holes, the female die core and the male die core are mutually embedded to form a hollow molding cavity, an upper air chamber and a lower air chamber are respectively formed on the upper side and the lower side of the female die core and the male die core, and a valve assembly for controlling the upper air chamber and the lower air chamber is further arranged.

When in foaming forming, the forming cavity is preheated by steam, then thermoplastic foaming plastic particles are filled in the forming cavity by a material gun, then high-temperature steam is injected into the steam chamber and enters the forming cavity through the air holes to melt foaming raw materials to form the required forming shape, then the forming cavity is cooled and formed, and finally the demoulding is carried out.

In above-mentioned foaming forming process, can form high-temperature condensate water after the high temperature steam condensation, consequently current integrated valve all sets a drain valve that is used for the drainage, and this drain valve is opened all the time at foaming forming process, but drain valve discharge bore has great size, can discharge high temperature steam in the drainage, causes steam extravagant, influences rate of heating.

In view of the above, the applicant has made an intensive study to solve the above problems and has made the present invention.

SUMMERY OF THE UTILITY MODEL

After the structure of the oil adding device is adopted, the utility model relates to a reduce extravagant improved generation collecting valve of steam, compare with prior art, beneficial effect lies in, open first drain valve before the foaming shaping, the steam condensate water that the indoor production of foaming shaping in-process gas gets into first drain valve after getting into first cavity, then from first drain valve to second cavity, discharge from the second cavity at last, because the drainage rate of first drain valve is not more than the formation speed of steam condensate water, make the steam condensate water slowly can hold and stay, finally form liquid front cover between first drain valve and lower air chamber. The first drain valve can be plugged up to the liquid seal face that forms for the comdenstion water can also continue outside discharge but most high temperature steam keeps in the shaping intracavity because of being blocked by water, has realized that only the drainage does not discharge steam or discharges steam less, prevents that high temperature steam from discharging, has practiced thrift the steam resource, has promoted foaming efficiency.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 5, an improved integrated valve for reducing steam waste comprises a main control box 1 and a first drain valve 2, wherein the main control box 1 comprises a first chamber 11 and a second chamber 12, the first chamber 11 is connected with a lower air chamber (not shown) of a mold through a water inlet and steam inlet 111, and the second chamber 12 is provided with a drain and steam outlet 121. The first drain valve 2 is arranged on the main control box 1, the first drain valve 2 is communicated with the first cavity 11 and the second cavity 12, the water inlet 21 of the first drain valve 2 is communicated with the first cavity 11, and the first water outlet 22 is communicated with the second cavity 12.

The first drain valve 2 is opened before foaming and forming of the integration valve, and only the first drain valve 2 is opened, so that steam in the lower air chamber can only be drained into the first drain valve 2 through the water inlet 21 after entering the first chamber 11, the steam forms condensed water in the foaming process, the condensed water flows into the second chamber 12 from the first water outlet 22, and finally the condensed water is drained out of the integration valve from the drain and steam outlet 121 of the second chamber 12. In whole drainage process, steam condensate water forming speed is V1, and the drainage speed of first drain valve 2 is V2, and V2 is not more than V1, and the comdenstion water can't once only be discharged like this, so steam condensate water can hold the accumulation gradually between first drain valve 2 and lower air chamber and form liquid front cover 5, first drain valve can be stopped up to liquid front cover 5 for the condensation water can continue outwards slowly to be discharged, but most high temperature steam has been realized only to drain and not steam or few steam of discharging because of being blockked by the comdenstion water and has been kept in the die cavity, prevents that high temperature steam from discharging, has practiced thrift steam resources, has promoted foaming efficiency.

Preferably, a water reservoir 23 communicated with the first water outlet 22 is arranged inside the first drain valve 2, and the water reservoir 23 is arranged between the water inlet 21 and the first water outlet 22. The reservoir 23 can be used to accumulate condensate, because the steam condensate is discharged inside the first drain valve 2 at a slower rate V2 than the steam condensate forming rate V1, and the undischarged condensate accumulates in the reservoir to form a liquid cover 5, which prevents the discharge of high-temperature steam.

Preferably, the water outlet 21 of the first drain valve 2 is arranged on the side wall of the second chamber, and the caliber size is within 1 inch, so that the size is reduced, and the draining speed of the first drain valve 2 can be reduced.

Preferably, the integrated valve further comprises a second water discharge valve 3, said second water discharge valve 3 communicating the first chamber 11 and the second chamber 12. When the second drain valve 3 is opened, the steam condensate can be discharged from the second water outlet 31 of the first chamber 11 to the second chamber 12 and then discharged from the drain steam outlet 121. However, the water discharge speed V3 of the second water discharge valve 3 is faster than the condensed water forming speed V1, so that part of the high temperature steam is discharged together during the water discharge. When a large amount of high-temperature steam needs to be discharged for cooling or a large amount of condensed water needs to be discharged after foaming and forming are completed, the second drain valve can be opened, and flexible adjustment is realized.

Preferably, the second water outlet 31 of the second drain valve 3 is arranged at the bottom of the first chamber 11, and the caliber size is between 3 and 5.

Preferably, the integrated valve further comprises a vacuum pumping valve 4, the main control box 1 further comprises a third chamber 13, the vacuum pumping valve 4 is communicated with the first chamber 11 and the third chamber 13, the third chamber 13 is provided with a vacuum pumping port 131 which can be connected with a vacuum pumping machine, and the raw material can be cooled by the vacuum pumping machine after foaming and forming.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
