Abstract
The utility model relates to a preheating device arranged at the outer surface of a mold. The device comprises a main body arranged at the outer surface of the mold, a channel is arranged in the main body, and a deflector communicated with the channel is arranged at the end of an air inlet of the channel. The preheating device can preheat the mold without the need of adding materials such as acid catalyst and the like, thus not only being capable of lowering the cost of manufacturing castings, but also being capable of shortening resin sand curing and stripping time, improving the quality of the castings, and also increasing the production efficiency of the castings.
Description
Technical field
The utility model relates to a kind of preheating device that is installed in mold outer surface.
Background technology
Resin sand is a kind of formed a kind of raw material after roughing sand and the mixed with resin.In the process of cast metal foundry goods, at first resin sand is squeezed in the die cavity of mould, the mode through heating makes its moulding again, then the mud core after the moulding is put into casting die and casts.Utilize resin sand to produce foundry goods, one side can make molten iron and mould isolate, and then the service life that can improve mould, can improve the fineness and the dimensional accuracy of cast(ing) surface on the other hand.Yet, because resin sand will be through the mode ability moulding of heating, if the temperature of mould is low excessively; Will prolong heat time heating time, and then can prolong resin sand curing and stripping time, not only wastes energy; But also can influence the efficient of producing foundry goods, also can influence the quality of foundry goods simultaneously.Particularly in the low area of environment temperature, like the north in winter, temperature is usually at subzero 20 ℃～30 ℃, and is quite long to resin sand curing and stripping time in the environment of this cold, and foundry goods also is difficult to reach desired quality standard.
In the prior art; Usually take the mode of catalyst to solve that resin sand solidifies and stripping time problem; As being binding agent with the furan resin-sand, and adding catalyst and mix and make molding sand, this kind mode can make sand mold solidify moulding voluntarily at normal temperatures; Catalyst wherein generally adopts acid catalyst, like furfuryl alcohol resin.Though acid catalyst can be through heating sand mold solidified, the problem that at first reflects is that the content of acid catalyst need be more than 50%, and then the raising cost of manufacture; In addition, in lower environment, promptly environment temperature, also is difficult to shorten resin sand and solidifies and stripping time below 20 ℃ the time subzero, and casting quality also is difficult for improving.
Summary of the invention
The task of the utility model provides a kind of utilization solves problems such as resin sand solidifies and grow stripping time to the mode of the prior heating of mould the preheating device that is installed in mold outer surface.
The preheating device that is installed in mold outer surface that the utility model proposed has the main body that is installed in mold outer surface, in main body, is provided with passage, and the air inlet end of this passage is equipped with the current divider that is connected with passage.
[0006]Said passage is provided with three.Said current divider is provided with two, and the input of each current divider is equipped with the input pipe fitting that is connected with air-heater, and the output of each current divider is equipped with the output pipe fitting that is connected with passage.
The preheating device that is installed in mold outer surface that the utility model proposed only adopts one to be arranged on the main body of mold outer surface and passage is set on main body, and its structure is quite simple, and cost of manufacture is lower; Simultaneously mould is heated in advance, need not add materials such as acid catalyst, not only can reduce the cost of making foundry goods, also can shorten resin sand and solidify and stripping time, improve the quality of foundry goods, and can also improve castings production efficient.
Description of drawings:
Accompanying drawing 1 is that the master of the embodiment of the preheating device that is installed in mold outer surface that proposes of the utility model looks the surface structure sketch map;
Accompanying drawing 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Referring to Fig. 1 and Fig. 2, these two accompanying drawings provide the surface structure sketch map of the embodiment of the preheating device that is installed in mold outer surface that the utility model proposes.This preheating device has the main body 1 and current divider 2 that an outward appearance is annular.This main body 1 can be enclosed within on the outer surface of mould (not providing among the figure), in main body 1, is provided with passage 11, and this passage 11 comprises air inlet 12 and exhaust outlet 13.Passage 11 is provided with three altogether, and each bar passage 11 is provided with two air inlets 12 and two exhaust outlets 13, and each air inlet 12 is connected with current divider 2 respectively.Current divider 2 is provided with two, and each current divider 2 has a housing 21, and the input of each housing 21 is equipped with the input pipe fitting 22 that is connected with air-heater 3, and its output is equipped with the output pipe fitting 23 that is connected with passage 11.When the hot blast of air-heater 3 outputs got into current divider 2, current divider 2 was input to hot blast in the passage 11 of main body 1 again, thereby can heat mould, so that the resin sand moulding.
