Abstract
The invention relates to a nozzle of an inorganic resin process temperature core box. The nozzle comprises a nozzle body and a nozzle head arranged at the lower part of the nozzle body; communicated sand shooting passages are formed in the nozzle body and the nozzle head; the nozzle body comprises a first nozzle body and a second nozzle body arranged in the first nozzle body; a cooling water passage is formed between the first nozzle body and the second nozzle body; the first nozzle body is provided with a water inlet and a water outlet; and the water inlet, the cooling water passage and the water outlet are connected and form an access. The cooling water passage arranged on the nozzle structure effectively cools the nozzle, so that the mixture of molding sand and inorganic resin in the nozzle is not cured due to over high temperature is ensured, blockage of the nozzle is avoided, and continuous batch production is realized.
Description
Technical field
The present invention relates to inorganic resin technology temperature core box, particularly relate to the nozzle of the use on the warm core box of this kind.
Background technology
At present, inorganic resin carries out coremaking with it and is widely used because environmental pollution is little.When carrying out the coremaking of inorganic resin technology, its main technique step is as follows: resin and molding sand mixing back are penetrated sand to core box from the nozzle of penetrating the sand plate, in core box core is cured.Wherein the difficult point of this technology is: the core of moulding is cured by the heating principle, and the sand environment temperature of penetrating of nozzle is raise.In general, nozzle self does not possess refrigerating function, phenomenon may just appear solidifying because temperature is higher in resin in nozzle and molding sand mixture in nozzle, cause its obstruction, thereby can not carry out continuous production, nozzle dredging and clear up and must wasting the working time, is influenced operating efficiency.
Summary of the invention
The invention provides a kind of nozzle that is applicable to heating-up temperature at 120～250 ℃ inorganic water-soluble resin core manufacturing craft temperature core box.
For achieving the above object, the technical solution used in the present invention is:
A kind of nozzle of inorganic resin technology temperature core box, comprise the nozzle body, be installed in the nozzle head of described nozzle body bottom, have in described nozzle body and the nozzle head be connected penetrate the sand passage, described nozzle body comprises the first nozzle body, be arranged on the second nozzle body of the described first nozzle body interior, between the described first nozzle body and the second nozzle body, has a cooling-water duct, offer water inlet and delivery port, described water inlet on the described first nozzle body, water cooling passageway and delivery port are connected and form path.
Preferably, the porch of described nozzle body is provided with steel wire, and the spacing of adjacent two steel wires is 4～8mm in the described steel wire.
Preferably, describedly penetrate the sand passage to be positioned at aperture, described nozzle head exit be 4～30mm.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
The present invention effectively cools off it by increase cooling-water duct on injection nozzle structure, guaranteeing that molding sand and inorganic resin mixture can not solidify owing to temperature is too high in the nozzle, thereby causes the obstruction of nozzle, realizes continuous batch production.
Description of drawings
Accompanying drawing 1 is a cross-sectional schematic of the present invention;
Accompanying drawing 2 is an A-A cutaway view in the accompanying drawing 1;
Accompanying drawing 3 is a B-B cutaway view in the accompanying drawing 2;
Accompanying drawing 4 is a steel wire schematic diagram of the present invention.
Wherein: 1, nozzle body; 10, the first nozzle body; 11, the second nozzle body; 2, nozzle head; 3, penetrate the sand passage; 4, water inlet; 5, delivery port; 6, steel wire; 7, nozzle cover; 8, cooling-water duct.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
The nozzle of a kind of inorganic resin technology temperature core box shown in Fig. 1～3, comprise and be installed in the nozzle body of penetrating on the plate 1, the nozzle head 2 that is installed in nozzle body 1 bottom, have in nozzle body 1 and the nozzle head 2 be connected penetrate sand passage 3, penetrating sand passage 3, to be positioned at aperture, nozzle head 2 exit be 4～30mm, is provided with nozzle cover 7 in the outer cover of nozzle head 2.
Wherein: nozzle body 1 comprises the first nozzle body 10, is arranged on the second nozzle body 11 of the first nozzle body, 10 inside.In the present embodiment, part forms a cooling-water duct 8 between the outside wall surface of the internal face of the first nozzle body 10 and the second nozzle body 11, penetrate sand passage 3 and the internal face of the second nozzle body 11 constitutes nozzle body 1 part, and offer water inlet 4 and delivery port 5 on the first nozzle body 10, water inlet 4, water cooling passageway 8 and delivery port 5 are connected and form path.
In addition, be provided with steel wire 6 in the porch of nozzle body 1, the spacing of adjacent two steel wires is 4～8mm in the steel wire 6.Sand stopped up in penetrating sand passage 3 when this steel wire 6 can effectively prevent to produce continuously, as shown in Figure 4.
When penetrating sand technology, resin and molding sand mix the back and inject core box by penetrating sand passage 3, and by being heating and curing.Simultaneously, feed cooling water in water inlet 4, cooling water flow is flowed out by delivery port 5 through water cooling passageway 8.Like this, cooling water can guarantee to penetrate that molding sand do not solidify because temperature after heating is too high in the sand passage 3, guarantees that it has flowability, stop up preventing, thus the production of realization continuous batch.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
