Abstract
The utility model discloses a sand removing device for shooting nozzles of a hot-box core shooter. The sand removing device comprises a hydraulic pump, a push rod, a top plate, shooting needles and a sand core mold. The upper end of the push rod is fixedly connected with the hydraulic pump, and the lower end of the push rod is fixedly connected with the top plate; small guide posts are fixedly arranged at two ends of the lower surface of the top plate; a plurality of shooting needles are fixedly arranged between the two small guide posts; small guide sleeves are inlaid at two ends of an upper mold plate of the sand core mold; the shooting nozzles with the same amount with the shooting needles are fixedly arranged between the two small guide sleeves; and the shooting needles and the shooting nozzles are in one-to-one correspondence, and are in clearance fit. With adoption of the sand removing device, after the hot-box core shooter finishes sand shooting of coated sand cores, the shooting needles press residual sand remained in the shooting nozzles into a die cavity of the sand core mold, so that the compactness of sand cores are enhanced, the shooting nozzles are cleaned, the sand cores can be easily demolded during mold unloading, and the production efficiency and the cast quality are improved.
Description
Technical field
The utility model relates to the foundry machinery field, relates in particular to a kind of hot box shoot core machine nozzle desanding device.
Background technology
Penetrate that system sand in coating phenolic resin core has advantages such as shaping speed is fast, the core appearance is bright and clean, the cleaning convenient, surface quality of continuous castings is good and the production that is widely used in the middle-size and small-size foundry goods that geometry is assorted again, surface requirements is bright and clean with hot box shoot core machine.When making core, hot box shoot core machine is penetrated sand in coating phenolic resin in the bucket at the die cavity of through the nozzle on the core mould cope match-plate pattern precoated sand being injected the core mould under the effect of air pressure.The prior art existing problems are: penetrate sand and finish to leave residual sand in the nozzle of back and link to each other with core, easy-to-draw evil idea of core and nozzle stop up when causing die sinking.
Summary of the invention
For addressing the above problem, the utility model provides a kind of hot box shoot core machine nozzle desanding device, hot box shoot core machine is penetrated the sand end to film covered sand core after, utilizes this device to remove the residual sand that leaves in the nozzle clean immediately.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of hot box shoot core machine nozzle of the utility model desanding device, it comprises push rod, top board, core mould.Described push rod upper end is fixedly connected with hydraulic pump; The lower end is fixedly connected with top board; The little guide pillar of the fixing assembling in the two ends of the lower surface of described top board, the some pins of penetrating of fixing assembling between two little guide pillars, the little guide pin bushing that the cope match-plate pattern two ends edge of described core mould is joined.
The further improvement of the utility model is: the cope match-plate pattern two ends edge of fixing little guide pillar of assembling in the two ends of the lower surface of top board and core mould is joined little guide pin bushing for movingly.
The further improvement of the utility model is: the fixing assembling nozzle identical between two little guide pin bushings with penetrating pin quantity, and it is corresponding one by one to penetrate pin and nozzle, and both are matched in clearance.
The beneficial effect of the utility model is: hot box shoot core machine is penetrated the sand end to film covered sand core after; Utilize this device immediately the residual sand that leaves in the nozzle to be pressed into the die cavity of core mould and strengthened the degree of packing of core; Cleared up nozzle again; Core is prone to the demoulding when making die sinking, has improved the quality of production efficiency and foundry goods.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is further described below, this embodiment only is used to explain the utility model, does not constitute the qualification of the utility model protection domain.
As shown in Figure 1: a kind of hot box shoot core machine nozzle desanding device of the utility model, it comprises push rod 1, top board 2, core mould 6.Described push rod 1 upper end is fixedly connected with hydraulic pump 5; The lower end is fixedly connected with top board 2, the little guide pillar 3 of the fixing assembling in the two ends of the lower surface of described top board 2, the some pins 4 of penetrating of fixing assembling between two little guide pillars 3; The cope match-plate pattern 7 two ends edge of described core mould 6 is joined little guide pin bushing 8; The fixing assembling nozzle 9 identical between two little guide pin bushings with penetrating pin 4 quantity, it is corresponding one by one with nozzle 9 to penetrate pin 3, and both are matched in clearance.The little guide pin bushing 8 that the cope match-plate pattern two ends edge of the little guide pillar 3 of the fixing assembling in the two ends of the lower surface of top board 2 and core mould is joined is for movingly.Hot box shoot core machine was penetrated sand and finished to precoated sand core 6 die cavities after, primer fluid press pump 5 made push rod 1 move to core mould 6, and under the guiding of little guide pillar 3 and little guide pin bushing 8, all pins 3 of penetrating get into the die cavity that residual sand that nozzles 9 will retain is pressed into core mould 6.
After the utility model is implemented, both strengthened the degree of packing of core, and cleared up nozzle again, core is prone to the demoulding when making die sinking, thereby has improved the quality of production efficiency and foundry goods.
