The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Utility model content
The purpose of this utility model is the nozzle plugging structure providing a kind of simple and reasonable diesel engine core mold, the nozzle plugging structure of this diesel engine core mold adopts rubber cushion blocks to carry out shutoff, rubber cushion blocks is fixed on lower core box, core shooter is shifted out with lower core box after die sinking, the convenient loose sand removed on rubber cushion blocks, long-pending sand under avoiding not having the nozzle of core, ensures that subsequent production nozzle matched moulds puts in place and penetrates carrying out smoothly of sand.
For achieving the above object, the utility model provides the nozzle plugging structure of diesel engine core mold, comprising: lower core box assembly; Upper core box assembly, working when penetrating sand, it be located in the end face of described lower core box assembly, and on this, the end face of core box assembly is disposed with and penetrates sand board component, air blowing board component, plunger tip board component; Nozzle, its be fixed on described in penetrate on sand board component, the sand end of penetrating of this nozzle stretches into described upper core box assembly; And elastic cushion block, it is fixed on the lower core box of described lower core box assembly, and the upper surface of this elastic cushion block abuts shutoff with the sand end of penetrating of nozzle.
Preferably, in technique scheme, elastic cushion block is rubber cushion blocks.
Preferably, in technique scheme, elastic cushion block is fixed on the lower core box of lower core box assembly by cushion block hold-down screw.
Preferably, in technique scheme, the cross section of elastic cushion block is circular.
Compared with prior art, the utility model has following beneficial effect: the nozzle plugging structure of this diesel engine core mold adopts rubber cushion blocks to carry out shutoff, rubber cushion blocks is fixed on lower core box, core shooter is shifted out with lower core box after die sinking, the convenient loose sand removed on rubber cushion blocks, long-pending sand under avoiding not having the nozzle of core, ensures that subsequent production nozzle matched moulds puts in place and penetrates carrying out smoothly of sand.
Accompanying drawing explanation
Fig. 1 is the structural representation of the nozzle plugging structure of diesel engine core mold of the present utility model.
Fig. 2 is the partial structurtes schematic diagram of the nozzle plugging structure of diesel engine core mold of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As depicted in figs. 1 and 2, according to specifically comprising of the nozzle plugging structure of the diesel engine core mold of the utility model detailed description of the invention: plunger tip board component 1, air blowing board component 2, penetrate sand board component 3, upper core box assembly 4, lower core box assembly 5, nozzle 6 and rubber cushion blocks 7, wherein, rubber cushion blocks 7 is fixed on the lower core box of lower core box assembly 5, for there is no the nozzle of core below shutoff diesel engine core mold, core shooter is shifted out with lower core box after rubber cushion blocks die sinking, the convenient loose sand removed on rubber cushion blocks, traditional nozzle shutoff mode is avoided to adopt in the direct rigidity shutoff of upper core box, sealing shroud is metal material, directly be fixed on upper core box with screw, nozzle directly contacts with sealing shroud, nozzle shutoff is unreliable, race sand is serious, the sand simultaneously dropped in sealing shroud is difficult to cleaning, loose sand is not fallen in cleaning can be affected subsequent production nozzle matched moulds and put in place, thus affect the matched moulds of mould and penetrate sand.
Specifically, upper core box assembly 4 works when penetrating sand, and it be located in the end face of lower core box assembly 5, plunger tip board component 1, air blowing board component 2, penetrate sand board component 3 end face being arranged on core box assembly 4 from top to bottom successively, wherein, plunger tip board component 1 passes air blowing board component 2 for flattening the sand of sand projection on each core.Nozzle 6 is fixed on to be penetrated on sand board component 3, and the sand end of penetrating of nozzle 6 stretches into core box assembly 4.
Rubber cushion blocks 7 is fixed on the lower core box of lower core box assembly 5 by cushion block hold-down screw 8, the upper surface of rubber cushion blocks 7 abuts shutoff with the sand end of penetrating of nozzle 6, for there is no the nozzle of core below shutoff diesel engine core mold, core shooter is shifted out with lower core box after rubber cushion blocks die sinking, the convenient loose sand removed on rubber cushion blocks, long-pending sand under avoiding not having the nozzle of core, ensures that subsequent production nozzle matched moulds puts in place and penetrates carrying out smoothly of sand.Preferably, the cross section of rubber cushion blocks 7 is circular.Cushion block hold-down screw 8 is two.
Such as, this diesel engine core mold comprises three cover core boxes, a set ofly penetrates sand plate, a set of air blowing plate and a set of plunger tip plate.Three cover core boxes are produced under a core shooter, and three cover core boxes share a set ofly penetrates sand plate, a set of air blowing plate, a set of plunger tip plate, and during core shooting, each core box changes another set of core box after penetrating system five cores and carries out core shooting.Share in order to three cover core boxes can be made and a set ofly penetrate sand plate, a set of air blowing plate, a set of plunger tip plate, reasonable Arrangement is wanted in core position, the core that shape is close is in same position when core shooting state, adjusts core position simultaneously, makes the distance of each core upper surface distance nozzle identical.
Have a set of core box to have two cores in three cover core boxes, other two cover core boxes have three cores, and only have the core box of two cores to be prevent from not having below when penetrating core processed the nozzle of core to run sand, this kind of nozzle of this cover core box needs to carry out shutoff.Rubber cushion blocks has spring energy effective sealing nozzle when core shooting, and rubber cushion blocks is screwed on lower core box, shifts out after die sinking with lower core box, the sand dropped on rubber cushion blocks be easy to cleaned fall.
To sum up, the nozzle plugging structure of this diesel engine core mold adopts rubber cushion blocks to carry out shutoff, rubber cushion blocks is fixed on lower core box, core shooter is shifted out with lower core box after die sinking, the convenient loose sand removed on rubber cushion blocks, long-pending sand under avoiding not having the nozzle of core, ensures that subsequent production nozzle matched moulds puts in place and penetrates carrying out smoothly of sand.
