Description
Technical field
The present invention relates to core shooter technical field, particularly relate to and a kind of there is the hot box shoot core machine taking out negative pressure system.
Background technology
Cast iron cooker be in daily life by cooking, steaming, boil, the means such as stir-fry, in order to food material to be processed into the utensil of edible item.Cast iron cooker adopts conventional casting methods to cast mostly, and the process of conventional cast cooker is roughly the following steps: first, makes mould according to cooker external form; Then, in mould, molding sand is cured; Secondly, the mould with molding sand is poured into a mould; Finally, shaping cooker is obtained by after mould parting.
Can use core shooter in the process being cured molding sand, core shooter is exactly Casting Equipment molding sand being become to have ad hoc structure by penetrating sand heating Post RDBMS.There are some problems in existing core shooter: (1) needs after producing sand mold, core manually sand mold, core to be taken out in actual application.(2) could pour into a mould after the sand mold produced, core need man-made assembly, automaticity is low.(3) casting process produces a large amount of gas, affects foundry goods shaping, and foundry goods easily produces pore, causes that the rough surface of foundry goods, dimensional accuracy are low and yield rate is low.(4) cooker of the cooker wall ratio coated sand technology production of clay-bonded sand casting is thicker.(5) pour into a mould under the condition of not taking out negative pressure, thin-section casting difficulty is shaping.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind ofly has the hot box shoot core machine taking out negative pressure system, and it is high that described core shooter has operating efficiency, the feature that cooker dimensional accuracy is high, any surface finish, thickness are thin of casting.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of have the hot box shoot core machine taking out negative pressure system, base is provided with guide rail and supporting plate, hot core box mould is arranged on the upper surface of base by supporting plate, hot core box mould comprises a left side, right half module and intermediate die plate, left, right half module moves left and right along guide rail under the effect of cylinder, a described left side, right half module is provided with electric heater unit, intermediate die plate under the effect of cylinder along it below guide rail move forward and backward, column is fixed on the centre of base, crossbeam is fixed on the upper end of column, penetrating sand device is arranged on crossbeam, cylinder and penetrate sand device and be controlled by control cabinet, it is characterized in that a left side of taking out negative pressure system and hot core box mould, negative pressure ventilation hole of taking out on right half module is tightly connected.
Preferred: the electric heater unit on left and right half module is electric heating tube.
Preferred: described in take out negative pressure system be vavuum pump.
The beneficial effect adopting technique scheme to produce is: by using described core shooter, take out negative-pressure operation to carry out on core shooter, and pour into a mould while taking out negative pressure, carry out again taking out negative-pressure operation and pouring operation after mould is taken off, pour into a mould while taking out negative pressure, accelerate the flowing velocity of iron liquid thus accelerate cooker shaping speed, and without the need to using miscellaneous equipment to carry out taking out negative-pressure operation, having saved operating procedure; Namely accelerate cooker shaping speed by using described core shooter and again save operating procedure, thus improve operating efficiency.By using described core shooter to pour into a mould while taking out negative pressure, be conducive to the casting of thin-walled cooker, thin-walled cooker thickness can be less than 3mm, and the cooker of production has the advantages that dimensional accuracy is high, any surface finish, casting deformation are little and yield rate is high.
In addition, by using hot core box mould casting process to use resin sand amount few, energy resource consumption is few, protection of the environment, reduces production cost; Matched moulds, parting etc. are carried out under operating in the control of control cabinet, and automaticity is high, improves production efficiency, reduces labour intensity, ensure that the personal safety of workman.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Wherein: 1, base 2, guide rail 3, supporting plate 4, left half module 5, right half module 6, intermediate die plate 7, cylinder 8, column 9, crossbeam 10, penetrate sand device 11, control cabinet 12, take out negative pressure system.
Detailed description of the invention
As shown in Figure 1, a kind of have the hot box shoot core machine taking out negative pressure system, and base 1 is provided with guide rail 2 and supporting plate 3, and hot core box mould is arranged on the upper surface of base by supporting plate 3; Hot core box mould comprises left and right half module 4,5 and intermediate die plate 6, and the left and right half module 4,5 of described hot core box mould is provided with electric heating tube and takes out negative pressure ventilation hole; Left and right half module 4,5 moves left and right along guide rail 2 under the effect of cylinder 7, intermediate die plate 6 under the effect of cylinder 7 along it below guide rail move forward and backward; Column 8 is fixed on the centre of base 1, crossbeam 9 is fixed on the upper end of column 8, penetrating sand device 10 is arranged on crossbeam 9, cylinder 7 and penetrate sand device 10 and be controlled by control cabinet 11, take out negative pressure system 12 to be tightly connected with the negative pressure ventilation hole of taking out on the left and right half module 4,5 of hot core box mould, take out negative pressure system and preferably use vavuum pump.
