Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," "up," "down," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1, a mold cooling device with a water separating sleeve comprises a mold 10, wherein a mold cooling hole 11 is formed in the mold 10 close to a cooling position, a water separating sleeve 20 is arranged in the mold cooling hole 11, a gap is formed between the water separating sleeve 20 and the mold cooling hole 11, and the gap is filled with a heat-conducting glue 40; a non-through flow channel with a cylindrical structure is arranged in the water separating sleeve 20, a water pipe 30 which is coaxially arranged is arranged in the flow channel, one end of the water pipe 30 is hermetically connected with the opening end of the flow channel, and the other end of the water pipe 30 is close to the bottom of the flow channel.
During operation, cooling liquid continuously flows in through the water inlet of the water pipe 30 and flows out from the water return port, heat generated during operation of the mold 10 is conducted into the cooling liquid through the heat conducting glue 40 and the waterproof sleeve 20 and is taken out by the cooling liquid, and cooling of the mold is achieved.
After the water-separating sleeve 20 is used, even if cracks are generated in the die 10 in use, due to the action of the water-separating sleeve 20, the cooling liquid is prevented from flowing to a die cavity through the cracks, and the die is prevented from being scrapped due to leakage of the cooling liquid. Meanwhile, when the cast product has higher cooling requirement during casting, the effects of improving the casting quality and improving the efficiency are achieved.
Further, the heat conducting adhesive 40 comprises, by mass, 4 parts of inorganic aluminosilicate powder: 2 parts of resol: 1 part of copper powder: and 3 parts of a solvent.
The heat-conducting glue 40 is a thermosetting heat-conducting glue, the actually measured heat conductivity coefficient can reach 10W/m.K (the heat conductivity coefficient of a mould material is generally 14-16W/m.K), the heat-conducting glue can be kept stable for a long time at a high temperature and is not decomposed, and meanwhile, the heat-conducting glue has a thermal expansion rate close to that of the mould material, so that cracking caused by inconsistent thermal expansion can be avoided, and the heat conduction is poor. It can be seen that the heat-conducting glue 40 is adopted as a heat-conducting and fixing material, and has good heat conductivity and stability.
When the heat-conducting heat-insulating sleeve is used, firstly, the surface of the water-insulating sleeve 20 is coated with the uncured heat-conducting glue 40, then the water-insulating sleeve 20 is inserted into the mold cooling hole 11, the heat-conducting glue 40 fills the gap between the water-insulating sleeve 20 and the mold cooling hole 11, and heat curing is carried out by using heat generated by fire baking or casting, and the heat curing time is about 2 hours, so that complete curing can be realized.
Further, the material of the water partition sleeve 20 is SUS303 stainless steel; SUS303 has low hardness and is easy to process.
Further, the clearance between the water separating sleeve 20 and the die cooling hole 11 is 0.2-0.5 mm.
Further, the distance A between the bottom of the mold cooling hole 11 and the surface of the mold is more than or equal to 5.0 mm.
After the water separating sleeve 20 is arranged, the distance between the bottom of the mold cooling hole 11 and the surface of the mold can be deeper than the distance between the bottom of the mold cooling hole and the surface of the mold in the prior art so as to be very close to the surface of the mold for cooling (the distance is as close as 5mm, and the distance is more than 15mm in the prior art); too small a distance may result in insufficient strength of the mold and cracks easily caused by stress.
Further, the bottom of the mold cooling hole 11 is shaped like a hemispherical arc, and the arc-shaped convex part is far away from the water pipe 30.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the present invention.
