Abstract
Aim at the tool of evaporative pattern flow coat process protection ingate; including bubbles model, ingate, external screw thread, ingate protective case, internal thread, band; bubbles model both sides are respectively equipped with ingate; ingate is equipped with external screw thread; the position close to bottom in ingate is arranged in external screw thread; it is cased with ingate protective case on the outside of ingate; ingate protective case inner wall is equipped with internal thread; internal thread is arranged in position corresponding with external screw thread; internal thread coordinates with external screw thread, and a circle band is equipped on the outside of ingate protective case.The utility model has the advantage of：It eliminates original process and is possible to the hidden danger that ingate goes out coating infiltration occur, can guarantee and completely eliminate because coating flows into foundry facing inclusion defect caused by ingate factor；In addition, ingate protective case can be used with Infinite Cyclic, production cost has been saved；Finally, the coating of ingate protective case recycling rear surface can again be utilized by the method for washing, improve the service efficiency of coating.
Description
Technical field
The present invention relates to Press Tools for Automobiles casting fields, more particularly to aim at evaporative pattern flow coat process protection ingate
Tool.
Background technology
Furane resins type lost foam casting is to obtain the direct moulding of bubbles model similar with product size by cast
The advantages that process of target casting, this kind of mode can improve casting dimension accuracy, reduced proper motion technique.To ensure to pour into a mould
System ingate has good combination effect with casting ontology, is just steeping the setting of papery ingate generally before painting type
On foam model, so that after painting type process, ingate pedestal can well became one with bubbles model.Paper is used before
The method that adhesive tape seals ingate, and the mode of operation that ingate is sealed to adhesive tape is repeatedly improved, but all poor strong man of effect
The case where meaning, viscosity weakens and often falls off after paper self-adhesive tape is soaked by coating；On the other hand, the paper self-adhesive tape intensity soaked is not
Often there is damaged situation in foot.The coating that both of which will appear painting type process enters the problems in ingate.For
Thoroughly eliminate this hidden danger, a kind of ad hoc cast gate protective case of rubber system of meter.
Invention content
According to the above technical problem, the utility model provides a kind of work aiming at evaporative pattern flow coat process protection ingate
Tool, it is characterised in that including bubbles model, ingate, external screw thread, ingate protective case, internal thread, band, the bubbles model
Both sides are respectively equipped with ingate, and the ingate is equipped with external screw thread, and the position close to bottom in ingate is arranged in the external screw thread
Set, ingate protective case be cased on the outside of the ingate, be equipped with 45 ° of chamferings at the ingate protective case inner wall, it is described in pour
Mouth protective case inner wall is equipped with internal thread, and the internal thread is arranged in position corresponding with external screw thread, the internal thread and external screw thread
Cooperation, the ingate protective case are fitted close with ingate, and a circle band is equipped on the outside of the ingate protective case.
The material of the ingate protective case is rubber.
The ingate material is phenolic sand molding dedicated paper.
The band material is rubber, and band internal diameter is slightly smaller than ingate protective case outer diameter
The beneficial effects of the utility model are：Ingate protective case is made of rubber, and there is certain elasticity, inner wall to be provided with
45 ° of chamferings, convenient for good fit with ingate；The internal thread of ingate protective case and the external screw thread of ingate coordinate, and increase
Frictional force, band further fasten the cooperation between ingate protective case and ingate, it is entirely avoided ingate is protected
Cover the case where it falls from ingate.The utility model, which eliminates original process and is possible to ingate occur to go out coating, to be oozed
The hidden danger entered can guarantee and completely eliminate because coating flows into foundry facing inclusion defect caused by ingate factor；In addition, interior pour
Mouth protective case can be used with Infinite Cyclic, for processing mode more originally, eliminate consumption of the paper self-adhesive tape in the operation, be saved
About production cost；Finally, the coating of ingate protective case recycling rear surface can again be utilized by the method for washing, be promoted
The service efficiency of coating.
Description of the drawings
Fig. 1 is the utility model assembly structure figure；
Fig. 2 is ingate protective case structural schematic diagram；
Fig. 3 is ingate enlarged structure schematic diagram.
Such as figure, bubbles model -1, ingate -2, external screw thread -3, ingate protective case -4, internal thread -5, band -6.
Specific implementation mode
Shown in below in conjunction with the accompanying drawings, the utility model is further described：The utility model is to aim at evaporative pattern stream
Apply the tool of process protection ingate, including bubbles model 1, ingate 2, external screw thread 3, ingate protective case 4, internal thread 5, beam
Band 6,1 both sides of bubbles model are respectively equipped with ingate 2, and 2 material of ingate is phenolic sand molding dedicated paper, and ingate 2 is equipped with
The position close to bottom in ingate 2 is arranged in external screw thread 3, external screw thread 3, and 2 outside of ingate is cased with ingate protective case 4, inside pours
The material of mouth protective case 4 is rubber, and 45 ° of chamferings are equipped at 4 inner wall of ingate protective case, and 4 inner wall of ingate protective case is equipped with interior
Screw thread 4, in position corresponding with external screw thread 3, internal thread 5 coordinates the setting of internal thread 4 with external screw thread 3, ingate protective case 4 with it is interior
Cast gate 2 is fitted close, and 4 outside of ingate protective case is equipped with a circle band 6, and 6 material of band is rubber, and 6 internal diameter of band is slightly smaller than
4 outer diameter of ingate protective case.
In use, before painting type starts, ingate protective case 4 is installed on ingate 2, makes internal thread 5 and outer spiral shell
Line 3 coordinates, and band 6 further fastens ingate protective case 4 and ingate 2, it is avoided to fall off, during playing painting type
The effect of barrier coating.Painting type process finishes, after bubbles model 1, the drying of 4 surface coating of ingate protective case, from
Ingate protective case 4 is removed on ingate 2, bubbles model can enter moulding process, and ingate protective case 4 can then lead to
The mode for crossing washing recycles, and scrubbing the coating water left can also recycling.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvement can also be made, these improvement are also answered
It is considered as the scope of protection of the utility model.
