Description
Technical field
The utility model belongs to the positioner of foundry sand type, particularly relates to a kind of self-hardening sand sand mold positioner.
Background technology
The foundry sand type generally is made up of first sand mold and second sand mold butt joint, and first sand mold is the primary condition that guarantees casting quality with accurate butt joint of second sand mold, so the sand mold positioner is one of primary structure in the self-hardening sand molding technology.
Following two kinds of sand mold detent mechanisms are arranged in existing self-hardening sand molding technology: a kind of is that the positioner that is made up of alignment pin and guide is set on last drag box, in order to confirm the relative position of sand mold.This detent mechanism generally need adopt the metal flask of casting, through the machining of sandbox mould assembling face and dowel hole being guaranteed quality of fit between sandbox and sandbox, sandbox and the template.Another kind of sand mold detent mechanism is to utilize self-hardening sand quick solidifying, operational characteristic that intensity is high; On upper and lower mould template, be provided with respectively can concavo-convex joint metal bump and recess; Protruding and recess is at least more than two pairs; Metal bump and recess form the convexity and the recess that are formed by self-hardening sand of concavo-convex opposite states on upper and lower half sand mold that solidifies, carry out the location between upper and lower half sand mold by this.
Above-mentioned second kind of detent mechanism positioning accuracy is general, but can satisfy common foundry goods required precision basically, and cost is cheap less than being strict with to the sandbox material.But because the intensity of the self-hardening sand of sand mold convexity is limited after all; The protruding about 40～50mm of maximum height; When higher sand mold mould assembly, often can't realize effective guiding, must carry out the sand mold cooperation of location in advance by manual work, otherwise will occur shoveling problems such as sand, shift.It is thus clear that there is the defective that production efficiency is low, the mould assembly precision is difficult to guarantee in existing self-hardening sand sand mold detent mechanism.
Summary of the invention
The utility model is to have the technical problem that production efficiency is low, the mould assembly precision is difficult to guarantee in order to solve existing casting industry self-hardening sand sand mold detent mechanism, and proposes a kind of self-hardening sand sand mold positioner.
The utility model is taked following technical scheme for realizing above-mentioned purpose: this positioner comprises the mould template; It is characterized in that: upper and lower mould template upper surface is respectively provided to few two support columns; The support column position of mould template is corresponding up and down; Each support column is respectively installed with the mould assembling alignment pin of metal; The said last mould assembling alignment pin that is set in mold template respective support post is an inversed taper platform shape, highly is equal to or greater than the thickness of first sand mold, and the centre hole axis that is engaged in support column is to running through the mould assembling alignment pin; The said following mould assembling alignment pin that is set in bed die template respective support post is positive taper type; Highly at least, equal the half the of second sand mold thickness, the central blind hole that is engaged in support column is extended with the screw section, and the cone bottom diameter of following mould assembling alignment pin is equal to or less than mould assembling inversed taper platform shape alignment pin cone bottom diameter; Said up and down mould assembling alignment pin in the central blind hole of mould assembling alignment pin centre bore and following mould assembling alignment pin is provided with the lift bar that make it concentric on it at last second sand mold during with sandbox mould assembling separately; Lift bar upper end is provided with transverse handle, and the bottom is provided with screw thread, and this screw thread bottom is threaded with the screw section that following mould assembling alignment pin central blind hole extends.
The utility model can also be taked following technical measures:
Said support column is arranged at the diagonal position of mould template up and down respectively, and the support column position of mould template is corresponding up and down.
The beneficial effect and the advantage of the utility model are: the metal of this positioner mould assembling alignment pin is up and down kept somewhere respectively in last second sand mold; At first use the lift bar to insert the centre bore of going up the mould assembling alignment pin; Insert the central blind hole of mould assembling alignment pin down subsequently again and be threaded with it, promptly realized that last drag box promptly goes up the accurate location of second sand mold this moment.On mention the case bar and can mould assembling alignment pin up and down be taken out from the sand mold of mould assembling.Only support column need be set on the mould template of this device, other accessories are general part, not limited by the size of sandbox, use flexibly; Mould assembling alignment pin length is enough to effectively carry out sand mold guiding and location up and down; The mould assembling alignment pin can recycle aborning up and down, helps reducing production costs.The utlity model has simple in structure, easy to use, sand mold accurate positioning and can thoroughly avoid shoveling the outstanding advantage of phenomenons such as sand, shift.
