Description
Technical field
The utility model relates to equipments machining die, is specially a kind of device making sand mold mould.
Background technology
Sand casting is the one in casting technique, and sand casting casting mold used is generally combined by outer sand mold and core.The Modeling Material used due to sand casting is cheap and easy to get, and Casting mold manufacturing is easy, and to the single-piece production of foundry goods, produce by batch and produce in a large number and all can adapt to, for a long time, be the basic technology in Foundry Production always.
Along with the research and development success of the core shooter for making core, due to the moulder's wage using core shooter moulding can save great number, so its application is more and more extensive.Core shooter adopts precoated sand coremaking, is applicable to hot box and cold-box two kinds.The feature of core shooter is application two guide pillars, folding mould vertical-parting.Core shooter operation principle is that core sand compound is injected in the core box after heating by being binding agent with liquid or solid thermosetting resin, core in core box preheating very rapid hardening to certain thickness (being about 5 ~ 10mm) by it taking-up, formed smooth surface, accurate in size high-quality core finished product.Its bonding agent used can give out some irritating smells after heating, and workman needs to wear mouth mask, and the place simultaneously worked needs to install ventilation fan to get rid of irritative gas.But, due to work often space is all larger in place, the limited use of ventilation fan, can not get rid of completely by irritative gas, causes the place of work still to have a large amount of irritative gas.
Utility model content
The purpose of this utility model is to provide a kind of device making sand mold mould, to solve problem irritative gas can not got rid of completely in prior art.
To achieve these goals, a kind of device making sand mold mould that the utility model provides, comprises dynamic model, cover half and exhaust apparatus; Described exhaust apparatus comprises air blowing part and air-breathing part, and air blowing part and air-breathing part are arranged at the both sides of dynamic model die joint respectively.
By arranging air-breathing part and air blowing part in the both sides of dynamic model die joint, when dynamic model and cover half are separated, air blowing part is ceaselessly blown toward mold parting surface inside, simultaneously air-breathing part ceaselessly air-breathing, make the air of mold parting surface inside produce convection current, thus irritative gas is taken away.
Compared with prior art, the advantage of this programme is: by arranging air blowing part and air-breathing part in the both sides of dynamic model die joint, thus being got rid of by irritative gas from source, avoiding irritative gas and being dispersed into environment, be not easy to get rid of completely.
Further, described air blowing part is arranged at the lower end of dynamic model, and air-breathing part is arranged at the upper end of dynamic model.Upwards can flow after air heat, so be provided with the disturbance being beneficial to and reducing air, get rid of irritative gas.
Further, described air blowing part is the pipe fitting being provided with gas hole, and the axis direction of pipe fitting is vertical with the die joint of mould, and is fixedly connected with dynamic model, and gas hole is just arranged air-breathing part.Make the gas hole of air blowing part be positioned at the downside of mold parting surface, the gas of producing by boasting all can enter mold parting surface.
Further, the lower end of described cover half is provided with the travel switch matched with part of blowing, and with hydraulic cylinder Electricity Federation.After dynamic model moves to certain position, touching travel switch, thus close hydraulic cylinder, thus realize automatically controlling.
Further, described travel switch is the travel switch of heat resistant type.Be conducive to the service life extending switch.
Further, described air-breathing part is the pipe fitting that sidewall is provided with suction hole, and the upper end of air-breathing part is provided with bridging piece, and the length that bridging piece is chosen is identical with the length of stretching out dynamic model of air blowing part, and tilts to the upper surface of cover half.To be conducive to the air that upwards flows, toward the side water conservancy diversion at suction hole place, preventing irritative gas from flying away away.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model makes the device of sand mold mould.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
In figure: hydraulic cylinder 1, dynamic model 2, air-breathing part 3, bridging piece 4, cover half 5, guide pillar 6, travel switch 7, air blowing part 8.
The device of making sand mold mould as shown in Figure 1, comprises dynamic model 2, cover half 5, exhaust apparatus, hydraulic cylinder 1 and frame.Frame is provided with guide pillar 6, and bottom and the guide pillar 6 of dynamic model 2 are slidably connected, and cover half 5 is fixedly connected with the right-hand member of guide pillar 6.Hydraulic cylinder 1 is connected with the left side of dynamic model 2.Exhaust apparatus is located on dynamic model 2, and exhaust apparatus comprises air blowing part 8 and air-breathing part 3.Air blowing part 8 is arranged at the lower end of dynamic model 2, and air blowing part 8 is for being provided with the pipe of gas hole, and the axis direction of air blowing part 8 is vertical with the die joint of mould, and is connected by U-bolt with dynamic model 2, and gas hole is just arranged air-breathing part 3.The lower end of cover half 5 is provided with the heat resistant type travel switch 7 matched with part 8 of blowing, and travel switch 7 is provided with plectrum, and air blowing part 8 can contact with plectrum, and can dial plectrum.Air-breathing part 3 is positioned at the upper end of dynamic model 2, air-breathing part 3 is provided with the square tube of suction hole for sidewall, the upper end of air-breathing part 3 is provided with bridging piece 4, and the length that bridging piece 4 is chosen is identical with the length of stretching out dynamic model 2 of air blowing part 8, and bridging piece 4 leaves the gap of three millimeters between the side of cover half 5 and the upper surface of cover half 5.
During use, dynamic model 2 and cover half 5 are in matched moulds state, and exhaust apparatus does not work.After sand mold mould is shaped, when needing to take out, primer fluid cylinder pressure 1, hydraulic cylinder 1 drives dynamic model 2 to move toward the direction away from cover half 5.Meanwhile, air-breathing part 3 and air blowing part 8 also work, when dynamic model 2 move to air blowing part 8 touch the plectrum of travel switch 7 time, hydraulic cylinder 1 just quits work, and now dynamic model 2 stops mobile.After dynamic model 2 keeps a period of time, primer fluid cylinder pressure 1 again, makes dynamic model 2 separate completely with cover half 5, and the plectrum of travel switch 7 resets due to the separation of air blowing part 8, thus closes exhaust apparatus.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
