Abstract

The utility model discloses a kind of mother matrix of lathe sand mold mould, it is inconvenient to solve the demoulding, the problem of sand mold out-of-flatness, its drip irrigation device is a kind of mother matrix of lathe sand mold mould, including mother matrix body, the mother matrix body has lathe surface characteristics, and the mother matrix body is made up of wooden materials, and any vertical plane of the mother matrix body is installed with epoxy plate.The mother matrix of lathe sand mold mould of the present utility model can make the sand mold mould of plane finishing, be easy to be stripped, and service life is grown, and cost is low.

Description

The mother matrix of lathe sand mold mould
Technical field
Machine tooling field is the utility model is related to, more specifically, it relates to a kind of mother matrix of lathe sand mold mould.
Background technology
The lathe that modern times use is typically to be made of cast iron, because cast iron materials intensity, rigidity are high, plastic deformation is small, resistance to Grit is high, and is easily worked, low cost, and in order to make the moulding of lathe fuselage, typically use after cast iron smelting Cast in mould so that the cast iron of liquid is cooled and shaped, so as to which the moulding of lathe be made.
During lathe of casting, mould is usually provided with two parts, and a part is casting body, and another part is mould Covered on tool, if the dry sand core made is placed in casting body first, forms runner between adjacent core, placing sand , it is necessary to which complete die cavity could be formed by covering lid on mold after core, these cores casting body is either upper to be covered The feature that there is lathe locally to be shown is required to, and these features are required to design mother matrix for being molded these features.
Mother matrix of the prior art is typically to be made up of wooden materials, and the moulding of lathe is made up of wood, then should Mother matrix is placed in cubical frame, and filling molding sand rear profile sand cooling is fixed-type so as to obtain the moulding on the outside of lathe, then Mother matrix is removed, but because the material property of wood in itself, cause made of wood that mother matrix service life is short, be often subject to heat Swollen shrinkage and be easily damaged, it is therefore desirable to frequently change, also have in the prior art certainly using aluminium sheet or foamed material, aluminium The cost of plate is high, is not easy to reduce production cost, and foamed material is then more prone to damage, therefore also only has minority to use, Therefore need to propose a kind of new scheme to solve the above problems.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of mother of lathe sand mold mould Version, makes its conveniently stripped, and the sand mold mould surface made is smooth, while the mother matrix service life is grown, and cost is low.
To achieve the above object, the utility model provides following technical scheme:A kind of mother matrix of lathe sand mold mould, bag Mother matrix body is included, the mother matrix body has lathe surface characteristics, and the mother matrix body is made up of wooden materials, the mother matrix sheet Any vertical plane of body is installed with epoxy plate.
By using above-mentioned technical proposal, epoxy plate will be set on the vertical plane of mother matrix body, because epoxy plate surface light Sliding, shrinkage is low, and mechanical property is good, and so epoxy plate is arranged on the vertical plane of mother matrix, when molding sand is filled in around mother matrix When fixed-type afterwards, relatively smooth face can be formed, while during the demoulding, because vertical face is to be easiest to occur The part for scratching or damaging, traditional wooden mother matrix can be damaged on vertical plane and cause shaping after sand mold damage from And result in the need for remaking sand mold mould or sand mold mould is repaired, so cause greatly increasing for cost, and incite somebody to action When vertical plane is replaced by epoxy plate, then vertical plane facilitates depart from during demoulding, and epoxy plate is unlikely to deform, and can be repeated Using several times without damage, saved financial cost.
Further, the epoxy plate is bolted on mother matrix body.
By using above-mentioned technical proposal, epoxy plate is bolted on mother matrix body, convenient installation, tied simultaneously Structure is firm, and stability is good.
Further, the epoxy plate offers counterbore, and the sunken end face of the bolt is in counterbore, and the end face of bolt It is generally aligned in the same plane with the surface of epoxy plate.
By using above-mentioned technical proposal, counterbore is opened up on epoxy plate, bolt is located at the surface with epoxy plate in counterbore It is consistent, so in the demoulding, bolt will not impact to the fluency of the demoulding, so as to ensure the flatness of sand mold.
Further, freezing plastic is filled with counterbore, freezing plastic fills the gap between bolt and counterbore complete.
By using above-mentioned technical proposal, freezing plastic is supplemented in the gap between bolt and counterbore, for filling-in gap, Do not penetrated into when molding sand is set in around mother matrix body in gap so, can so ensure the flatness of mould surface.
The utility model tool has the advantage that compared with prior art:The wooden mother matrix that in the market is commonly used is changed in wood Epoxy plate is installed, the surface of epoxy plate is smooth, and shrinkage is low, is unlikely to deform, so as to sand on the vertical plane that mother matrix processed is easily damaged Type is conveniently stripped when being stripped, and surface smoothness is high, and the service life length of epoxy plate, and making many times can be repeated With not interfering with the precision or finish of sand mold, while low manufacture cost, meet the requirement of energy-saving and emission-reduction.
Brief description of the drawings
Fig. 1 is the structural representation of the mother matrix of the utility model lathe sand mold mould.
In figure:1st, mother matrix body;2nd, epoxy plate;3rd, bolt.
Embodiment
The utility model is described in further detail below.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
The mother matrix of lathe sand mold mould, as shown in figure 1, including mother matrix body 1, mother matrix body 1 is made up of wooden materials, female The surface of version body 1 has some regularly or irregularly shape facilities, and the lathe that this feature makes required for determines, The moulding of mother matrix body 1 is substantially consistent with the outer contoured features for the lathe to be made, if mother matrix body 1 now has Dry perpendicular, epoxy plate 2 is installed with some perpendiculars, the quantity of the epoxy plate 2 is according to mother matrix sheet Vertical plane possessed by body 1 determines, and carries out considering selection according to the size of actual vertical plane, can if less vertical plane With selection without installing epoxy plate 2, and the mounting means of epoxy plate 2 passes through bolt then using counterbore is opened up on epoxy plate 2 3 pass through counterbore after be threadedly coupled with mother matrix body 1 so as to form fixation, and the end face of fixed rear bolt 3 and the table of epoxy plate 2 Face is kept maintaining an equal level, if slightly error, freezing plastic is filled in the gap of counterbore and bolt 3, then carries out floating, thus can The surface for enough making epoxy plate 2 is flat smooth on the whole, the sand mold mould smooth this makes it possible to make surface.
