The processing cost of evaporative pattern is added, applicability and practicality are restricted.
The content of the invention
The purpose of this utility model is to provide the gear box of micro-cultivator shell that a kind of structure setting is reasonable and stability in use is good
Body casting evaporative pattern, it is intended to solve the poor technical deficiency of evaporative pattern versatility in conventional art.
The technical scheme for realizing the utility model purpose is a kind of gear box of micro-cultivator shell cast evaporative pattern, including is disappeared
Lose die body, the disappearance die body includes bottom model section and side form portion, it is identical and for square sheet mould that the bottom model section includes structure
There is screens strip groove on body, the symmetric side of the sheet die body, have card on two sides of residue of the sheet die body
Position is raised, and the raised thickness of the screens is identical with the width of screens strip groove, adjacent sheet die body by screens projection and
Screens strip groove is connected, and cross guiding channel, the side of the cross guiding channel are provided with the sheet die body
Edge is in the center of sheet die body side, provided with guiding circular hole in the side form portion, the side bottom in the side form portion have with
The outlet that the guiding circular hole is connected, the edge of the bottom model section cements in side bottom and the institute in side form portion by bonded adhesives
State outlet with the port of cross guiding channel to be connected, cementation has at connection flanging of the side form portion with the bottom model section
High temperature resistant reinforcement.
Lateral surface in the bottom surface of the bottom model section and side form portion scribbles refractory masses, and the high temperature resistant reinforcement glues
Gu in the outside of refractory masses.
There are ingate and small ventilating holes, the top phase of the ingate and the guiding circular hole on the top in the side form portion
Connection, the small ventilating holes are connected with the lower end of the guiding circular hole.
The high temperature resistant reinforcement is the ceramic muscle body of non-oxide beryllium.
The utility model has positive effect：Reasonable in the structure setting of utility model, bottom model section uses combining structure,
So as to be adjusted and change as needed, then side form portion is adhesively fixed with bottom model section, by more than bottom model section side
Edge is eliminated, and versatility is used so as to greatly improve it, solves in conventional art the poor technology of evaporative pattern versatility not
Enough, and at the connection flanging in bottom model section Yu side form portion there is high temperature resistant reinforcement, it is ensured that side form portion and the company of bottom model section
Stability is connect, the quality of casting is advantageously ensured that to a certain extent, strong applicability and practicality is good.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to the utility model, wherein：
