Abstract
The utility model discloses a kind of sprocket wheel mould, its drip irrigation device comprises pedestal, pedestal offers tank, also include die cavity and polylith and be arranged at model block in tank, the all detachable settings with pedestal of described model block, described die cavity is joined end to end to enclose by model block and forms, and model block is at least provided with four pieces, and the sidewall of model block is all fitted with the inwall of tank.The purpose of this utility model is that providing a kind of can carry out effective sprocket wheel mould processed by husky bits.
Description
Technical field
The utility model relates to a kind of mould, and more particularly, it relates to a kind of sprocket wheel mould.
Background technology
Sprocket wheel mould is used for the casting of sprocket wheel.The mould of the large-scale sprocket wheel of current tradition is all generally be made up of sandstone, and is formed in one setting as shown in Figure 4, so can there is shortcoming.Because sprocket wheel has been cast, and when taking out from mould, because sprocket wheel and mould are for fitting tightly state, therefore through friction each other, the inwall of mould can drop lower sand bits a lot, and these husky bits can drop in the die cavity of mould, because mould is integrated setting, so can dead angle be there is in die cavity, therefore the sand bits entering dead angle are difficult to be eliminated totally, and can only be come by whole die flip sand bits to pour out, but (quality comparatively greatly on the one hand, and staff is not easy to move, overturn to consider the quality of mould itself and problem of materials; On the other hand because mould is sandstone material, so in the process of moving upset, perhaps can arrive grinding tool and cause damage), so be not suitable for utilizing which to clear up sand bits, so the accuracy of next sprocket wheel casting can be had influence on.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of can carry out effective sprocket wheel mould processed by husky bits.
For achieving the above object, the utility model provides following technical scheme: a kind of sprocket wheel mould, comprises pedestal, pedestal offers tank, also include die cavity and polylith and be arranged at model block in tank, model block all detachable settings with pedestal, die cavity is joined end to end to enclose by model block and forms.
Preferably, model block is at least provided with four pieces.
Preferably, the sidewall of model block is all fitted with the inwall of tank.
Preferably, every block models block is provided with convenient draw ring model block upwards pulled.
Compared with prior art, the utility model has the advantages that: when producing husky bits in die cavity, corresponding model block upwards can be promoted, then sand bits are swept into the dead angle place of tank inwall, and then model block is put down, make the outside of the cleaned die cavity formed to being enclosed by polylith model block of husky bits, namely husky bits are between model block and tank inwall, thus this sand bits just can not have influence on the casting of sprocket wheel, also the utility model need not be carried out moving upset simultaneously.

Reference numeral: 1, pedestal; 2, die cavity; 3, model block; 4, tank; 5, draw ring; 6, chamfering.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model sprocket wheel Die Embodiment is described further.
A kind of sprocket wheel mould, comprises pedestal 1, and the block that pedestal 1 is square is arranged; Pedestal 1 offers tank 4, the rounded setting of this tank 4; Simultaneously in the utility model, also include die cavity 2 and polylith and be arranged at model block 3 in tank 4, in the utility model, model block 3 is made up of earthy material, die cavity 2 for the cast molding of sprocket wheel, model block 3 all with the detachable setting of pedestal 1 (namely model block 3 is placed in tank 4), die cavity 2 is joined end to end to enclose by model block 3 and forms, namely the end conflict bonded to each other often on adjacent two block models blocks 3, around formation circle and toothed die cavity 2.In the utility model, model block 3 all with the detachable setting of pedestal 1 (being namely placed in tank 4), and due to die cavity 2 be combined to form by polylith model block 3, and the cast molding of sprocket wheel is in die cavity 2, so sprocket wheel is when cast molding, can not connect with the inwall of the dead angle at tank 4 inwall place and tank 4 and contact, so cast at sprocket wheel, when taking out from die cavity 2, even if there is spare to drop, only model block 3 upwards need be mentioned, then spare is swept into the inwall place of tank 4, and then model block 3 is put down, thus make to there is not spare in die cavity 2, thus just can not have influence on the normal casting of sprocket wheel, on the other hand, in the utility model, model block 3 utilizes earthy material to make, because the spare fallen down from earthy material can be less than the particle of sand bits, thus can occupy less space in tank 4, make the utility model have more practicality.
Further, model block 3 is at least provided with four pieces, and in the utility model, model block 3 is provided with eight pieces, because when arranging eight pieces, the quality comparation of every block models block 3 is moderate, namely facilitates staff to be mentioned; And when arranging too much model block 3, the space of consecutive phantom block 3 joining place is just more, the normal casting of sprocket wheel can be had influence on, so arranging eight is the preferred of the technical program.
Further, the sidewall of model block 3 is all fitted with the inwall of tank 4, and the crest line at the corresponding dead angle of model block 3 is set to chamfering 6, and model block 3 fits to conflict with the inwall of tank 4 and arranges, can increase model block 3 be enclosed to form die cavity 2 after stability, namely model block 3 is not easily shifted; On the other hand, the setting of chamfering 6, can increase the stability of model block 3 equally, because after crest line is arranged to chamfering 6, this chamfering 6 position can not touch with the spare being swept into dead angle place, so substantially increase the stability of model block 3 to a certain extent.
Further, every block models block 3 is provided with the convenient draw ring 5 model block 3 upwards pulled, the gripping of staff can be facilitated to have an effect by this draw ring 5, thus just can be convenient model block 3 is upwards pulled from tank 4.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
