Abstract
The utility model discloses a vibrating sand-shooting cold-box used for manufacturing the sand core with deep holes or deep grooves by shooting. A vibrator used for vibrating the cold-box during the sand-shooting or after the sand-shooting to enable the core sand positioned inside the cold-box to be fully filled in the deep hole or the deep groove parts is installed on the vibrating sand-shooting cold-box. The vibrator is started during the sand-shooting or after the sand-shooting to drive the cold-box to vibrate together with the core sand, and enables to fill the deep hole or the deep groove parts with the core sand under the vibration, so that the sand core prepared in this way has the advantages of complete shape, high qualification rate, no repairation as well as high production efficiency.
Description
Technical field
The utility model relates to a kind of vibrating sand-shooting cold box.
Background technology
Triethylamine cold core technology is to inject in the core box die cavity with the mixed silica sand of resin, to be blown into the triethylamine gas of heating again, and the chemistry reflection takes place, and solidifies, and forms core at last, is used for casting pouring.Present Al-alloy heat exchanger, in order to improve heat conduction efficiency, the burning chamber has several small columns, correspondingly, the deep hole that several shape small column positions are arranged on the core during coremaking, when the core shape has deep hole or zanjon situation, push rod can't be set, only penetrate sand and can cause deep hole, ditch position to penetrate unreal with common cold-box, the coremaking qualification rate is low, the core shape is imperfect, needs to repair core, greatly reduces production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of vibrating sand-shooting cold box, and this cold-box is when penetrating fixture the core of deep hole or zanjon is arranged, and core sand can fully be filled deep hole or zanjon position.
In order to reach above purpose, the technical solution adopted in the utility model is: a kind of vibrating sand-shooting cold box, be used to penetrate the core that fixture has deep hole or zanjon, be equipped with on this cold-box be used for when penetrating sand or penetrate sand after vibrations core box make the core sand that is positioned at it fully fill the electromagnetic shaker at deep hole or zanjon position.
Underframe is arranged at the bottom of described cold-box, and described electromagnetic shaker is installed in the underframe, is connected with the connection base plate in the bottom of underframe by elastic component.
Described elastic component is a spring, and upright on the described connection base plate have spring guide pillar, and described elastic component is set on the described spring guide pillar.
Be fixed with spacing column on the described connection base plate, offer through hole on the described underframe, described spacing column passes described through hole, and there is the limited block of forbidding that described underframe excessively moves up the end that described spacing column passes described through hole, and the width of described limited block is greater than the width of described through hole.
Because the utility model has adopted above technical scheme, its advantage is: when penetrating sand or after penetrating sand, the starting shock device, electromagnetic shaker drives core box and core sand shakes together, utilize vibrations to make core sand tamp deep hole or zanjon position, the core shape that makes like this is complete, and qualification rate is very high, need not to repair, production efficiency is also high.
Description of drawings
Accompanying drawing 1 is that master of the present utility model looks cutaway view.
The specific embodiment
Further set forth concrete structure of the present utility model and operation principle below in conjunction with accompanying drawing.
A kind of vibrating sand-shooting cold box, be used to penetrate the core that fixture has deep hole or zanjon, comprise frame, penetrate sand mechanism, plunger tip mechanism, the core box clamping positioning mechanism, gas generator and controlling organization, adopt the cold-box of vertical die sinking, core box is generally by a left side, right mould is formed, in Fig. 1, penetrate some nozzles are installed on the sand plate 1, the head of nozzle stretches into core box 3 and penetrates sand, underframe 4 is arranged at the bottom of cold-box, the core box clamping positioning mechanism, core box 3 is contained on the underframe 4, electromagnetic shaker 5 is installed in the underframe 4, electromagnetic shaker 5 also can be installed in four sides of core box as required, and electromagnetic shaker 5 drives core box 3 and shakes when penetrating sand or after penetrating sand, the core sand that is positioned at core box 3 deep holes or zanjon position is fully tamped, bottom at underframe 4 is connected with connection base plate 11 by elastic component 7, specifically, the bottom of underframe 4 is connected with an end of elastic component 7 by cushion block 6, and the other end of elastic component 7 is connected and connects on the base plate 11.Elastic component 7 is a spring, and connecting to stand on the base plate 11 has spring guide pillar 8, and elastic component 7 is set on the spring guide pillar 8.When not penetrating sand, elastic component 7 is supporting underframe 4 and core box 3, and when penetrating sand or after penetrating sand, starting shock device 5, electromagnetic shaker 5 drive underframe 4, core box 3 and core sand and shake together, utilize vibrations to make core sand tamp deep hole or zanjon position.For guaranteeing the smooth and easy of shock motion, elastic component 7 sideslips when avoiding penetrating the sand vibrations simultaneously, elastic component 7 is set on the spring guide pillar 8, and guide pillar 8 play the guiding role.
Connect on the base plate 11 and be fixed with spacing column 10, offer through hole on the underframe 4, spacing column 10 passes through hole, and there is the limited block 12 of forbidding that underframe 4 excessively moves up in the vibrations process end that spacing column 10 passes through hole, and the width of limited block 12 is greater than the width of described through hole.In Fig. 1, spacing column 10, limited block 12 are wholely set into hexagon-headed bolt, and hex nut 9 is housed on the hexagon-headed bolt, and hex nut 9 can forbid that underframe 4 excessively moves down.Excessively move down when in fact, spring guide pillar 8 also can play the vibrations of restriction underframe 4 and sideslip during underframe 4 vibrations.
To sum up, this cold-box utilizes the vibrations core sand can fully fill deep hole or zanjon position when penetrating fixture the core of deep hole or zanjon is arranged, and the core shape that makes like this is complete, and qualification rate is very high, need not to repair, and production efficiency is higher.And this core shooter is mechanical connection manner, and motion is reliable, stable.
