Abstract
The present invention relates to a casting process, specifically to a positioning process adopted for a bolt hole sand mold. According to the present invention, the implementation process is simple, a plurality of fixation cores are added to the sand mold, such that the bolt hole sand mold is easy to exactly position, and the disadvantages of easy breaking or defect of the bolt hole column sand core are solved so as to improve the production efficiency.
Description
Technical field
The present invention relates to a kind of casting technique, concrete relate to a kind of positioning process that is applicable to the bolt hole sand mold.
Background technology
Some foundry goods of in casting industry, producing, what have has a bolt hole structure that is used to connect miscellaneous part at least, connects more fast, accurately in order to make parts, and therefore shape, the position to its bolt hole proposed higher requirement.
At present, have the foundry goods of bolt hole, though can bolt directly be cast out, exempted the operation of follow-up machining, improved work efficiency, when making the bolt hole core, contained bolt hole post core very easily ruptures or is damaged.
Summary of the inventionDefective in view of prior art exists the objective of the invention is to provide a kind of bolt hole sand mold positioning process, and this kind features simple and practical process can effectively guarantee the machining accuracy and the location of bolt hole.
For realizing above-mentioned purpose, the technical solution that the present invention adopted:
A kind of bolt hole sand mold positioning process is characterized in that:
Its process is following:
(1) mfg. moulding die and bolt hole core box;
(2) preparation of core, sand mold: preparation foundry goods agent structure core and bolt hole core, described bolt hole core comprise annulus part and some protruded stigmas that adapts with diameter of bolt hole that has; The bolt hole core is socketed on the foundry goods agent structure core.
(3) core after will making up is put in the sand mold, and mould assembling, cast, post processing form foundry goods.
The molding sand of described foundry goods agent structure core adopts clay-bonded sand; The bolt hole core is selected furane resins or resol for use.
Described its characteristic of bolt hole core also is: add the plurality of fixed fuse in the core, fixedly fuse adopts the I shape steel bar, in the core fixedly the quantity of fuse decide by the bolt aperture.
The present invention has the following advantages:
Implementation process of the present invention is simple, adds the plurality of fixed fuse in the core, is beneficial to the accurate location of bolt hole sand mold, has solved bolt hole post core simultaneously and has very easily ruptured or damaged defective, has improved production efficiency.
Description of drawings
Fig. 1 cross-section structure simplified schematic diagram of the present invention;
Fig. 2 fixed core minor structure sketch map.
Among the figure: 1, foundry goods agent structure core, 2, the bolt hole core, 3, fixing fuse.
The specific embodiment
Specify below in conjunction with embodiment:
At first need mfg. moulding die and bolt hole core box; Next carries out the preparation of core, sand mold: preparation foundry goods agent structure core 1 and bolt hole core 2, and the molding sand of described foundry goods agent structure core 1 adopts clay-bonded sand; Bolt hole core 2 is selected furane resins or resol for use; Described bolt hole core 2 comprises annulus part and some protruded stigmas that adapts with diameter of bolt hole that has; In bolt hole core 2, add plurality of fixed fuse 3, fixedly fuse 3 adopts the I shape steel bars, in the core fixedly the quantity of fuse 3 decide by the bolt aperture; Then bolt hole core 2 is socketed on the foundry goods agent structure core 1; Core after will making up at last is put in the sand mold, and mould assembling, cast, post processing form foundry goods.
Claims (2)
1. bolt hole sand mold positioning process is characterized in that:
Its process is following:
(1) mfg. moulding die and bolt hole core box;
(2) preparation of core, sand mold: preparation foundry goods agent structure core and bolt hole core, described bolt hole core comprise annulus part and some protruded stigmas that adapts with diameter of bolt hole that has; The bolt hole core is socketed on the foundry goods agent structure core.
(3) core after will making up is put in the sand mold, and mould assembling, cast, post processing form foundry goods.
The molding sand of described foundry goods agent structure core adopts clay-bonded sand; The bolt hole core is selected furane resins or resol for use.
2. according to the said a kind of bolt hole sand mold positioning process of claim 1, it is characterized in that: add the plurality of fixed fuse in the described bolt hole core, fixedly fuse adopts the I shape steel bar, in the core fixedly the quantity of fuse decide by the bolt aperture.
