Abstract
The present invention discloses a kind of localization method of multilayer sand core block longitudinal stack, which comprises the steps of: production positioning plate；Nowel sand mold is placed to steady, the stacking first layer sand core block on the supporting surface of nowel sand mold, the plug hole with the cooperation of the cavity shape of multilayered structure casting is preset on the sand core block；The location graduation plate made is inserted into again in the plug hole of first layer sand core block, and is located on the supporting surface of nowel sand mold；Successively multilayer sand core block is successively piled up, positioning plate both passes through preset plug hole on every layer of sand core block；Positioning plate is extracted out from top after the superposition of all sand core blocks, then is poured to obtain multilayered structure casting through mould assembling.The present invention can effectively prevent core shift, after every layer of sand core block has been superimposed when lower core, checks whether sand core block height has deviation using the scale on positioning plate, can accurately guarantee casting dimension.
Description
Technical field
The present invention relates to the sand casting production field of casting, the positioning side of specifically a kind of multilayer sand core block longitudinal stack
Method.
Background technique
At present when Steel Castings some by the similar structure composition of multilayer, multilayer sand core block longitudinal stack shape is usually used
At casting mold or sand core block, as shown in Fig. 2, nowel sand mold is placed steadily, positioning pin is put after placing first layer sand core block, then according to fixed
Position pin places second layer sand core block, places multilayer sand core block block by this method, then be poured to obtain casting through mould assembling.Multilayer sand core block
Between superposition usually rely on positioning pin carry out positioning sand core block, due to every layer of positioning pin all can there is a certain error, multilayer
A biggish scale error may can be generated after superposition, causes shift core shift, so that the underproof probability of product size increases
Add, also increases the workload reprocessed, or even casting is caused to scrap.
Summary of the invention
The purpose of the present invention is to provide a kind of localization methods of multilayer sand core block longitudinal stack, to solve above-mentioned background skill
The problem of being proposed in art.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that:
A kind of localization method of multilayer sand core block longitudinal stack, includes the following steps:
S1, production positioning plate: positioning plate is produced according to the cavity shape of multilayered structure casting with the shape, then on positioning plate
It depicts and the high corresponding graduation mark of the layer of multilayered structure casting；
S2, nowel sand mold is placed to steady, stacking first layer sand core block, the sand core block on the supporting surface of nowel sand mold
On be preset with the cavity shape of multilayered structure casting cooperation plug hole；
S3, again by the plug hole of the location graduation plate made insertion first layer sand core block, and be located at nowel sand mold
Supporting surface on, and check whether first layer sand core block height and the first layer graduation mark height on positioning plate concordant；
S4, when first layer sand core block height is concordant with the first layer graduation mark height on positioning plate, successively by multilayer sand
Pellet is successively piled up, and positioning plate both passes through preset plug hole on every layer of sand core block, and is checked respectively for every layer of sand core block height and be
It is no concordant with corresponding graduation mark height；
S5, positioning plate extracted out after the superposition of all sand core blocks from top, then is poured to obtain multilayered structure casting through mould assembling.
Further, the first layer graduation mark height on the first layer sand core block height in the S1 step and positioning plate is not
It, can be by the sand core block of replacement proper height, if the height of sand core block is higher than the first layer graduation mark on positioning plate when concordant
Highly, also the height of sand core block can be reduced, keep graduation mark height corresponding thereto concordant by way of polishing.
The beneficial effects of the present invention are:
The present invention provides a kind of localization method of multilayer sand core block longitudinal stack, can effectively prevent core shift, when lower core
After every layer of sand core block has been superimposed, checks whether sand core block height has deviation using the scale on positioning plate, can accurately guarantee
Casting dimension.
