Abstract
The utility model discloses one and penetrate wax machine nozzle, belong to model casting field.This is penetrated wax machine nozzle and comprises wax conveying tube, nozzle housing, shower nozzle and piston, it is characterized in that: be provided with piston in wax conveying tube inside, and piston and wax conveying tube fit tightly and can slide in wax conveying tube; The bar linkage structure controlled is provided with after described piston; Be provided with groove in the middle part of described wax conveying tube, outermost end is provided with limited step, and forms sealed cavity between wax conveying tube and nozzle housing; Described shower nozzle is pyramid type structure.The utility model effectively solves the insulation problem of penetrating wax in wax machine nozzle and prevents leakage problem.
Description
Technical field
The utility model belongs to model casting field, is specifically related to one and penetrates wax machine nozzle.
Background technology
Model casting, also claims lost-wax casting: select suitable expendable pattern material system (as paraffin) to make fusible pattern, fusible pattern repeats be stained with fireproof coating and spread fire sand operation, sclerosis shell and drying; Again the fusible pattern of inside is melted away, obtain die cavity; Roasting shell to obtain enough intensity, and burns remaining expendable pattern material; Metal material required for cast; Solidify cooling, sand removal after shelling, thus obtain high-precision finished product.In the prior art, general employing is penetrated wax machine and is carried out making fusible pattern, by penetrating wax machine wax, the grown form of product is showed.The temperatures as high 60-90 degree Celsius of wax in operation, when of short duration break-off, wax remaining in nozzle easily solidifies and causes spray nozzle clogging, and cleaning trouble, again heats and can cause scale error because of wax temperature difference.Simultaneously remaining in nozzle wax injection or leakage can cause waste, can increase cost for a long time.
Utility model content
The utility model provides one and penetrates wax machine nozzle, and the wax penetrated in wax machine nozzle can be kept not solidify when of short duration break-off, and the wax in nozzle also can not produce leakage.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Penetrate wax machine nozzle, comprise wax conveying tube, nozzle housing, shower nozzle and piston, it is characterized in that: be provided with piston in wax conveying tube inside, piston and wax conveying tube fit tightly and can slide in wax conveying tube; The bar linkage structure controlled is provided with after described piston; Be provided with groove in the middle part of described wax conveying tube, outermost end is provided with limited step, and forms sealed cavity between wax conveying tube and nozzle housing; Described shower nozzle is pyramid type structure.
Described piston is soft rubber material.
Described shower nozzle is in wax conveying tube in first beginning and end duty, can slide.
The beneficial effects of the utility model are:
One, form toroidal cavity between wax conveying tube and nozzle housing, add constant-temperature hot water in the cavities, when of short duration break-off, the wax in nozzle also can not solidify, and avoids blocking and penetrates wax nozzle;
Two, be provided with piston in wax conveying tube inside, and piston being soft rubber material, when not working, good sealing function can being played, the wax of wax conveying tube can not be revealed;
Three, shower nozzle is in wax conveying tube in first beginning and end duty, and the constant-temperature hot water formed in toroidal cavity between wax conveying tube and nozzle housing can be utilized to keep wax in shower nozzle not solidify;
Four, be provided with groove in wax conveying tube, coordinate with piston, when piston moves to groove, just enter duty, fill wax to shower nozzle, when piston moves on groove, wax conveying tube seals, and upwards inhales wax remaining in shower nozzle simultaneously.The open/close state of good Control Nozzle, makes the wax of shower nozzle to reveal waste simultaneously, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 be nozzle housing, 2 be groove, 3 be piston, 4 be bar linkage structure, 5 be wax conveying tube, 6 be shower nozzle, 7 for limited step.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described.
As shown in Figure 1, penetrate wax machine nozzle, comprise wax conveying tube 5, nozzle housing 1, shower nozzle 6 and piston 3.Form toroidal cavity between wax conveying tube 5 and nozzle housing 1, add constant-temperature hot water in the cavities, when of short duration break-off, wax conveying tube 5 also can not solidify with the wax in nozzle 6, avoids blocking.Penetrate wax nozzle when non-duty, bar linkage structure 4 moves to right, and make piston 3 be in the right of groove 2, piston 3 selects elastomeric material, now can seal, and shower nozzle 6 is in wax conveying tube 5.When starting working, promote bar linkage structure 4 to be moved to the left, piston 3 moves to groove 2 place thereupon, and now piston 3 sealing function lost efficacy, liquid wax flows into cone shape shower nozzle 6 from groove 2, under the active force of wax, shower nozzle 6 is moved to the left, and stretches out wax conveying tube, wax conveying tube outermost end is provided with limited step 7, blocked by shower nozzle, shower nozzle no longer moves, and operation is carried out.When stopping when working, bar linkage structure 4 moves right, and drives piston 3 homing to the right, now, because of piston action, no longer includes wax and enter shower nozzle, produce one suction simultaneously, shower nozzle is sucked back original position, and wax remaining in shower nozzle also can not be revealed.Groove 2 in wax conveying tube 5 and the open/close state of the no-float Control Nozzle of piston 3, make the wax of shower nozzle to reveal waste simultaneously, cost-saving.
Claims (3)
1. penetrate a wax machine nozzle, comprise wax conveying tube, nozzle housing, shower nozzle and piston, it is characterized in that: be provided with piston in wax conveying tube inside, piston and wax conveying tube fit tightly and can slide in wax conveying tube; The bar linkage structure controlled is provided with after described piston; Be provided with groove in the middle part of described wax conveying tube, outermost end is provided with limited step, and forms sealed cavity between wax conveying tube and nozzle housing; Described shower nozzle is pyramid type structure.
2. one as claimed in claim 1 penetrates wax machine nozzle, it is characterized in that: piston is soft rubber material.
