Abstract
The invention relates to a method for threaded connection between cast moulds and cores and between the cores, and belongs to the technical field of casting. To enable the conventional method for connection between the cast moulds and the cores and between the cores to be convenient and quick, the method provided by the invention is to finish fixed connection between the cast moulds and the cores and between the cores through threads; and the threads can be general threads, conical threads or trapezoidal threads. Therefore, the method not only can be used for conveniently finishing fixed connection between various types of the cast moulds and the cores and between the cores but also is quicker and safer in comparison with the conventional method, and is especially suitable for quickly fixing the cores on mould lines.
Description
Technical field
The invention belongs to casting technology field, be specifically related to the thread connection method between a kind of casting mold and fuse and fuse and the fuse.
Background technology
In casting technology field, casting mold adopts clay-bonded sand, oil-sand, resin sand, water-glass sand, cement bonded sand to make usually, fuse adopts oil-sand, resin sand, water-glass sand, cement bonded sand to make usually, being connected and fixed between casting mold and fuse and fuse and the fuse, can adopt respectively plug pin according to different situations, binding agent or with the mode that is fixedly connected such as iron wire and bolt.
The fuse that the casting mold that clay-bonded sand is made and oil-sand are made fixing as shown in Figure 1, clay-bonded sand lower mold 1, oil-sand fuse 2 is used for fixing the iron nail 3 of fuse, drag box 4 because clay-bonded sand intensity is low, fuse 2 and lower mold 1 adopt the mode of dowel nail to fix usually.
The lower mold that resin sand is made and fuse fixing as shown in Figure 2, lower mold 1, fuse 2, drag box 3.Because resin sand has preferably dry strength, usually adopt the binding agent bonding to realize the fixing of fuse and casting mold, but the casting mold after the bonding must be heating and curing.
The fuse that the upper mold that clay-bonded sand is made and cement bonded sand are made fixing as shown in Figure 3, clay-bonded sand upper mold 1, cement bonded sand fuse 2 is used for fixing the iron wire 3 of fuse, cope 4.Because fuse 2 is suspended in the upper mold 1, in such cases, clay-bonded sand upper mold 1 adopts the fixed form of dowel nail can't realize with cement bonded sand fuse 2, can only adopt the mode of iron wire binding to fix; Although the casting mold of other composition material has higher intensity, because the adhesion strength of binding agent has certain limitation, generally also adopt iron wire binding mode to fix, particularly weight fuse bigger than normal adopts iron wire binding mode to fix usually.
At present, the casting mold of being made by the heterogeneity material and fuse cause the fixed form that connects between casting mold and fuse, fuse and the fuse different, and the common mode that is connected and fixed respectively has its limitation, thus, how to develop the connecting mode between casting mold simple and easy to do, that can generally adopt and fuse, fuse and the fuse, be the correlative study staff the direction and goal in the urgent need to striving for.
Summary of the invention
The technical problem that (one) will solve
The technical problem to be solved in the present invention is to take different fixed forms for replacing traditional casting mold of making according to the heterogeneity material from fuse, connecting mode between a kind of casting mold simple and easy to do, that can generally adopt and fuse, fuse and the fuse is provided, namely utilizes the mode of thread connection to realize being fixedly connected of casting mold and fuse and fuse and fuse.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides the thread connection method between a kind of casting mold and fuse and fuse and the fuse, its technical scheme is to be to be fixed by threaded connection between described casting mold and fuse and fuse and the fuse.
Wherein, described fuse is with external screw thread, is fixed by threaded connection with lower mold or the fuse of the internal thread that is complementary with the external screw thread with fuse.
Wherein, described fuse is with external screw thread, and the sand swivel nut by the internal thread that is fixedly installed in lower mold or the fuse and is complementary with the external screw thread with fuse is fixedly connected with lower mold or fuse.
Wherein, described fuse is fixedly connected with upper mold or fuse by with the resin sand bolt and the resin sand nut that mutually mate screw thread.
Wherein, described sand swivel nut, sand bolt and sand nut are made by resin sand, water-glass sand, cement bonded sand or oil-sand.
Wherein, screw thread described above is regular screw threads, tapered thread or trapezoidal thread.Contact area between tapered thread, the trapezoidal thread is larger, and the bearing capacity ratio regular screw threads are larger.
(3) beneficial effect
Compared with prior art, the present invention possesses following beneficial effect:
Thread connection method between the casting mold that technical solution of the present invention provides and fuse and fuse and the fuse can realize being fixedly connected of casting mold that all kinds, various material are made and fuse, fuse and fuse easily.And because resin sand, water-glass sand, cement bonded sand or oil-sand have higher tensile strength, can bear larger load, can suspend larger fuse in midair, broken through originally to only have and adopted upper mold that metal material could realize and the fixed form between the fuse, and faster more safer than conventional method, the quick of fuse that this threaded connection mode especially is fit on the mo(u)lding line fixed.
