Abstract
The invention discloses a kind of casting mould assembling dowel device with magnet, including top box sand mold and nowel sand mold, the upper location dimples that top carries steel plate are equipped in the top box sand mold, lower location dimples are equipped in the nowel sand mold, upper location dimples are opposite with the lower opening of location dimples, and upper location dimples are equipped with the positioning pin with magnet with the cavity of lower location dimples formation, when top box sand mold and nowel sand mold mould assembling, positioning pin with magnet is adsorbed in upper location dimples, facilitates row to hang on case sand mold and mould assembling is accurately positioned.The mould assembling dowel device, it is simple and reliable, pass through the steel plate being arranged at the top of upper location dimples when the magnet and the moulding that are embedded in positioning pin upper surface, positioning pin is adsorbed in upper location dimples when mould assembling, it is operated convenient for accurate mould assembling, avoids drawback and the jiggly problem of mould assembling that traditional mould assembling positioning pin can be only put in lower location dimples.
Description
Technical field
The invention belongs to machine casting fields, and in particular to a kind of casting mould assembling dowel device with magnet.
Background technology
In hardened sand casting, sand mold hardens molding, core under upper painting, upper and lower sand mold mould assembling.Mould assembling is last one of moulding
Critical process, it is desirable that engage accurate positioning when upper and lower sand mold mould assembling, horizontal four direction and vertical direction cannot have deviation.It is no
Then casting mismatch, size will be caused not to be inconsistent, casting mold runout, casting grinding workload are increased or scrapped.
In traditional hardening sand molding production process, usually using the upper location dimples of top box sand mold, nowel sand mold
Lower location dimples and metal fitting nail position mould assembling.Its metal fitting nail can be only put in lower location dimples, be hung in practical row
In mould assembling operating process, there is prodigious drawback, visually upper location dimples mould assembling positioning is inconvenient, and be easy to cause positioning mould assembling not
Steadily, cavity occurs to wipe sand, false type question with sand core.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of, and the casting mould assembling positioning pin with magnet fills
It sets, improves the stationarity of positioning mould assembling, prevent mould assembling from wiping sand, the generation of shift defect.
In order to solve the above technical problems, the technical scheme is that：
This carries the casting mould assembling dowel device of magnet, including top box sand mold and nowel sand mold, it is characterised in that：The top box
Be equipped with the upper location dimples with steel plate in sand mold, be equipped with lower location dimples in the nowel sand mold, upper location dimples with it is lower fixed
The opening of position pit is opposite, and upper location dimples are equipped with the positioning pin with magnet with the cavity of lower location dimples formation,
When top box sand mold and nowel sand mold mould assembling, the positioning pin with magnet is adsorbed in upper location dimples, and row is facilitated to hang accurate positionin
Mould assembling.
Preferably, the upper surface center of the positioning pin is inlaid with dual face strengthened magnet.
Preferably, steel plate is embedded at the top of the upper location dimples in moulding, the size of the steel plate is more than upper positioning
Pit top perimeter size 10mm or more.
Preferably, the upper location dimples are frustum of a cone pit, and the lower location dimples are the symmetrical size of upper location dimples
Frustum of a cone pit.
Preferably, the positioning pin is symmetrical frustum of a cone overall structure broad in the middle, both ends are small.
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of casting mould assembling dowel device with magnet, passes through the strong magnets inlayed at the upper surface center of positioning pin
And the pre-buried steel plate at the top of upper location dimples, positioning pin installation is adsorbed in upper location dimples, top box sand mold and nowel sand
When type mould assembling, under the lower end aligned of positioning pin in location dimples, row is facilitated to hang positioning mould assembling operation.The mould assembling dowel device,
It is simple in structure, it positions reliable convenient, improves row and cod the stationarity of type positioning mould assembling, prevent from wiping sand, shift defect occurs.
