Description

A kind of spelling loam core formula simple die

Technical field

This utility model relates to casting technology field, spells loam core formula simple die particularly to one.

Background technology

Mould, in commercial production in order to be molded, to be blow molded, to extrude, die casting or the method such as forging forming, smelting, punching press obtain The various moulds of required product and instrument.In brief, mould is used to the instrument of formed article, and this instrument is by various parts Constituting, different moulds is made up of different parts.It mainly realizes article by the change of institute's moulding material physical state The processing of profile.Have the title of " mother of industry ".Wherein, during a lot of steel-casting production it is all the life using full pattern wooden model Product mode, makees an overall wooden model, and wood model structure needs very firm, and manufacturing cost is at a relatively high, such a product needed ten The die cost of several ten thousand, adds production cost virtually, in Vehicles Collected from Market is competed, it is impossible to occupy market.In consideration of it, this reality A kind of spelling loam core formula simple die is provided with novel.

Summary of the invention

In order to solve the problems referred to above, this utility model provides a kind of spelling loam core formula simple die.

To achieve these goals, this utility model realizes by the following technical solutions: a kind of spelling loam core formula low-cost die Tool, including loam core and wooden model；Described wooden model is nested in outside loam core, and lateral wall, loam core is close to mutually with wooden model medial wall, mud Core is in " U " type shape structure, and upside outer wall and the downside outer wall in loam core are straightway, and the left side outer wall in loam core is also straightway, The outer right wall in loam core caves inward, and the outer right wall in loam core is in " Ω " type shape；Described wooden model is tied in " U " type shape housing Structure, and wooden model rear and front end is hatch frame.

As further improvement of the utility model, described wooden model material is kahikatea wood.

During production, first by good to loam core and the Wooden Pattern Making of side, carry out the most the other way around opposite side loam core and The making of wooden model, and the loam core of both sides is the most identical with wooden model shape and size, it is not necessary to do any conversion, only need to carry out twice adding Work, the loam core finally made both sides and wooden model piece together and define a complete sand mo(u)ld.

The beneficial effects of the utility model are: a kind of loam core formula simple die of spelling has simple and compact for structure, operation letter The features such as single and cost of manufacture is low, compared to existing technology, it is by spelling the sculpting method in loam core, it is not necessary to produce unitary mould, Greatly reduce production cost, shorten the Mold Making time, thus shorten the production cycle of product.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Fig. 1 is the front view of existing mold (full pattern wooden model)；

Fig. 2 is front view of the present utility model.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under Face combines and is specifically illustrating, and this utility model is expanded on further.It should be noted that in the case of not conflicting, in the application Feature in embodiment and embodiment can be combined with each other.

As shown in Fig. 1 and Fig. 2, a kind of spelling loam core formula simple die, including loam core 1 and wooden model 2；Described wooden model 2 Being nested in outside loam core 1, and lateral wall, loam core 1 is close to mutually with wooden model 2 medial wall, loam core 1 is in " U " type shape structure, loam core 1 Upside outer wall and downside outer wall be straightway, the left side outer wall in loam core 1 is also straightway, the outer right wall in loam core 1 to Sunken inside, and the outer right wall in loam core 1 is in " Ω " type shape；Described wooden model 2 is in " U " type shape shell structure, and before wooden model 2 Rear two ends are hatch frame, and wooden model 2 material is kahikatea wood.

During production, first loam core 1 and the wooden model 2 of side are made, carry out the mud of opposite side the most the other way around Core 1 and the making of wooden model 2, and the loam core 1 of both sides is the most identical with wooden model 2 shape and size, it is not necessary to do any conversion, only Twice processing need to be carried out, the loam core 1 finally both sides made and wooden model 2 piece together define one complete Sand mo(u)ld, above-mentioned this sand mo(u)ld (as shown in Fig. 2) is by spelling the sculpting method in loam core 1, it is not necessary to produce unitary mould, significantly Reduce production cost, shorten the Mold Making time, thus shorten the production cycle of product；Avoid as a lot of cast steels During part production all be use full pattern wooden model 3(as shown in Fig. 1) the mode of production, do an overall full pattern wooden model 3, full pattern Wooden model 3 structure needs very firm, and manufacturing cost is at a relatively high, the die cost of such a product needed tens0000, virtually Add production cost, in Vehicles Collected from Market is competed, it is impossible to occupy market.

Of the present utility model ultimate principle, principal character and advantage have more than been shown and described.The technical staff of the industry It should be appreciated that this utility model is not restricted to the described embodiments, the simply explanation of the description in above-described embodiment and description Principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has various change Change and improve, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims model Enclose and defined by appending claims and equivalent thereof.
