Description of the Invention: » Technical Field of the Invention The present invention relates to a heating and heat preservation device, and more particularly to a heating and heat preservation device for molten metal. [Prior Art] The conventional metal component manufacturing methods are roughly three types of cutting, casting and forging. Among them, the so-called cutting process is to use the cutting tools such as lathe, milling machine, CNC machine tool (C〇mputer Numericai control, # CNC), etc. to directly process the metal blank into metal components; casting (Casting) is The metal billet is heated to melt into a liquid metal, and the liquid metal is injected into a mold cavity of a previously formed metal component to form a metal component; and Forging is to place the metal billet into different molds. Pressure is applied to form the metal components. However, the slow processing speed is not suitable for the production of a large number of metal components; casting is easy to form pores and shrinkage holes in the fabricated metal components; forging is directly forged metal blanks, so the forging The metal components of the production # will have high residual stress. In order to overcome the shortcomings of the above manufacturing methods, related companies have developed Semi-Solid Forming (SSF), which refers to a technique in which materials are molded in a solid and liquid state. When the metal material is in a semi-solid state, a part of the solid particles and the liquid molten material surrounding the solid particles together form a semi-solid slurry. The biggest key point of the semi-solid molding technology is to control the molten metal. In the semi-solid state of the melt, however, most of the existing semi-solid molding devices lack the thermal insulation equipment suitable for 201111069. Therefore, the existing semi-solid molding devices are as shown in the patents of U.S. Patent Nos. 5,836,372 and 6,135,196, which will be used. The heating furnace for heating and melting the metal billet is placed on the molding machine to directly feed the semi-solid melt into the molding machine to prevent the semi-solid melt from being excessively cooled to affect the molding. However, since the heating furnace is disposed on the molding machine, it is necessary to consider the load that the molding machine can bear, so that the volume of the metal blank that can be contained in the existing heating furnace is very limited, so that new metal is frequently added during molding. The billet, due to the addition of the metal billet, will cause the temperature to drop and reheat, which seriously affects the smoothness of the processing. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a heating and holding device for a molten metal which can precisely control the temperature and make the process smoother. Thus, the heating and holding device for molten metal of the present invention comprises a base: a heating and holding unit disposed on the base, a holding unit located in the heating and holding unit, and a driving unit for driving the holding unit. The heating and holding unit includes a cover disposed on the base and forming an accommodating space, a heater that can controllably heat the accommodating space, and a note formed on the cover and communicating with the accommodating space a material port, and a take-up opening formed on the cover and communicating with the receiving space. The accommodating unit comprises a plurality of cartridges spaced apart from each other in the accommodating space and containing a molten metal for the month b; the driving unit includes a predetermined condition for driving the cartridge along a passage through the injection opening and the take-up opening A drive group that moves the path, and a power source that can controllably drive the drive group. The utility model has the advantages that the heater is used to heat the accommodating space to make the 201111069 position: the cartridge in the accommodating space can maintain the set temperature, and avoid the over-cooling of the metal contained in the accommodating space. The production of molten metal: the temperature difference between inside and outside can not only make the process smoother, but also avoid the energy consumption of repeated heating to reduce the production cost. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention are provided below and below. The detailed description of the preferred embodiment with reference to the drawings will be apparent.

The driving unit 14 includes a power source 141 disposed on the base raft and located under the cover 122, and a drive group 142 that can be driven by the power source 141. The drive group 142 has A support frame 143 that can be rotated by the power source i4i and an indexing plate 144 that is disposed on the support frame 143 and cooperates with the accommodating space 121 to form an annular shape. In the preferred embodiment, the indexing plate 144 is also made of a heat-insulating ceramic material. The accommodating unit 13 includes sixteen cartridges 131 which are disposed at an equal angle and spaced apart from the indexing disk 144 and located in the accommodating space 121. Each of the cartridges 131 has a housing 132 detachably disposed on the indexing plate 144, and a cartridge body 33 that can be detachably engaged in the housing 132. In the preferred embodiment, the base 132 and the casing 133 are made of a metal material. Referring to Figures 3 and 4, the molten metal heating and holding device of the present invention is further disposed in a metal semi-solid molding apparatus, and the metal semi-solid molding apparatus 100 includes a melting apparatus 1〇1, and A molding device 1〇2 disposed at a distance from the melting device ι〇ι, and the heating and holding device! It is disposed between the melting device 101 and the molding device 102. Wherein, the smelting apparatus 1〇1 has a heating furnace 103 capable of heating the metal material into a smelting metal, and a first robot arm 104 capable of heating the molten metal in the furnace 1〇3 from the spoon, the molding apparatus 102 including A die casting machine 1〇5 spaced apart from the heating furnace 1〇3, and a second robot arm 1〇 spaced apart from the die casting machine 1〇5. The injection port 124 of the heating and holding unit 12 faces the first robot arm 1〇4, and the take-up port 125 faces the second robot arm 1〇6. It is specifically noted herein that the molten metal obtained by heating the metal material in the preferred embodiment is a semi-solid metal paste. 201111069 For convenience of explanation, the following description is taken as an example of producing an alloy of aluminum alloy, which is an aluminum alloy melt 200 in which an aluminum alloy billet (not shown) is heated to a molten state, and the heater 123 is The cartridge 13丨 located in the accommodating space 12丨 is heated to 600t: ～66 (rc, and then the power source 141 is activated (shown in FIG. 1) to make the indexing plate 144 according to the arrow in FIG. The first robot arm 1〇4 is in the molten state of the aluminum alloy melt 200 in the heating furnace 1〇3, and the aluminum alloy melt 2 is poured into the guiding member 126. The gravity molten aluminum alloy slurry 2 is transferred into the casing 133 of the cartridge 131 located in the injection port 124 and located under the guide member 126 by gravity, because the temperature of the cartridge 131 is Between 6 〇〇 and 660 ° C. Therefore, the aluminum alloy melt 200 which can effectively control the molten state in the cartridge 131 is in a semi-solid molten state, and the temperature of the cartridge 131 is prevented from being too low to cause a molten state. When the aluminum alloy melt 2 〇〇 flows into the magazine ΐ3, the temperature is too fast to produce excessive cooling. The phenomenon causes the temperature difference between the center and the edge of the aluminum alloy melt 200 in a molten state to be excessively large. The cartridge 131 containing the aluminum alloy melt 2 in a molten state is driven by the indexing plate 144, according to the figure. The direction indicated by the arrow 15 passes through the holding zone 129 to enter the take-up port 125, and the heat retaining zone 129 can reheat the cartridge 131' to ensure that the molten aluminum alloy in the cartridge 13 is molten. Presenting a semi-solid molten state, the second robot arm 1 〇 6 then grips the casing 133 ′ located in the take-up opening 125 and containing the molten aluminum alloy melt 200 and melts the casing 133 The aluminum alloy melt 2 of the state is poured into the die casting machine 1〇5 so that the die casting machine 1〇5 can produce the aluminum alloy from the aluminum alloy melt 2 in the molten state of the casing 133. Product, 201111069 Finally, the second robot arm 106 then returns the box i33 to the corresponding seat 132 in the take-up port, so that the box ι31 continues to be driven by the indexing disc* into the heating zone. In 128, the case 133 which was originally cooled by contact with air is again brought up. Raise to between 600 ° c and 66 ° c for the next - I process. a It is to be noted that the heater 123 'power source ΐ 4 i and the first and second robot arms 1 〇 4, The control of the die casting machine 1〇5 belongs to the prior art in the field of control technology, and therefore will not be further described herein. With the above design, the heating and heat insulating device of the molten metal of the present invention is applied in practical applications. The utility model has the following advantages: 1. Smoothness of the same manufacturing process: the heating and heat preservation device 1 can keep the molten metal away from the heating furnace 103 and remain in the semi-solid molten state, and also causes the melting device 101 to be combined with the molding device. 102 is spaced apart to have a volume of 5, which avoids the trouble of re-heating the metal blanks to be re-heated; and the cartridges 131 are disposed on the indexing disk 144 at equal intervals and located in the accommodating space 121 The process can be continuously carried out without interruption, effectively improving the smoothness of the process. 2. Improving the quality of the product: the heater 123 is used to heat the equiangularly spaced arbitrarily disposed on the indexing plate 144 and the cartridge 131' located in the accommodating space '2 is allowed to continue when the molten metal reaches the cartridge 131. Keeping it in a semi-solid state, not only can the temperature of the molten metal contact with the crucible 131 be too fast (4) to become internal defects, but also maintain better fluidity and improve product quality and production speed. 3. Low production cost: Continued above, it can improve the smoothness of the process and produce 201111069: quality and production speed, thus effectively reducing production operation costs and improving product competitiveness. In summary, the heating and holding device of the molten metal of the present invention uses the heater 123 to heat the accommodating space 121, so that the magazine 131 located in the accommodating space can maintain the set temperature and avoid the contained Excessive cooling of the molten metal causes the internal and external temperature difference of the molten metal in the accommodating space, which not only makes the process smoother, but also reduces the energy consumption of repeated heating, solves the internal defects of products that may be generated by excessive cooling, and improves the production. Απ贝, and reduce the production cost, it is indeed the object of the present invention. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
