Description of the Invention (1) [Technical Field of the Invention] The present invention relates to a cast product formed by pouring molten metal into a disappearing mold and forming Its manufacturing method. [A brief description of the prior art] For example, the stator frame (Statbr frame) of a rotary electric motor has a substantially cylindrical shape, and an opening for ventilation is provided at the central portion of the wall portion in the axial direction. The cooling air used to cool the motor winding is discharged to the outside through this opening. The above-mentioned stator frame is traditionally manufactured by the inlay method. An example of the method of assembling the stator frame will be described below with reference to FIGS. 52 to 56. First, the outer sand mold 1, the inner sand mold 2 shown in Figure 5 3, and the sand core 3 for the mouth as shown in Figure 5 4 are produced. In this situation, the outer sand mold 1 is made as shown in Figure 55, that is, a rectangular container-like mold 4 is housed with a circle having an outer diameter that is almost equal to the outer diameter of the stator frame. In the state where the cylindrical inner mold 5 is fixed, sand is placed between the two molds 4 and 5 and then hardened to make it. The inside sand mold 2 and the sand core sand mold 3 are made by inserting sand into the cavity of a mold (not shown) that can be divided into two pieces, and then hardening it. Then, the convex portion 3 a protruding from the core sand mold 3 is fitted into the concave portion 2 a on the outer peripheral portion of the inner sand mold 2, and the sand core 3 is installed in the inner sand mold 2. The mold clamping operation contained in the outer sand mold 1. After that, in the cavity 6 formed by the sand molds 1, 2, and 3, the molten metal is poured as shown in Fig. 56 (please read the precautions on the back before writing this page) This paper music scale uses Chinese National Standards (CNS) Grade 4 specifications (210x297) 1-3-printed by the Ministry of Agriculture, Industry and Consumer Cooperatives 31 199119 Λ 6 _; _Β6 ___ V. Description of invention (2) Make it. In this way, the stator frame can be manufactured. In addition, the opening of the cast stator frame is fixed with bolts or the like to protect the protective member made of a net or the like for safety reasons. However, in the above-mentioned conventional method, when the sand mold 3 is installed in the sand mold 3, only the convex portion 3a of the sand core mold 3 is fitted into the concave portion 2a of the inner sand mold 2, so the sand core Mode 3 saw the poor positioning accuracy of the mouth, which is where the humiliation lies. In order to solve this shortcoming, it was suggested that another way is to set a recess in the outer sand mold, and at the same time set a sand core sand mold for fitting on the outer sand mold The convex part of the concave part, using the outer sand mold and the inner sand mold to perform the positioning of the sand mold. However, according to this configuration method, it is necessary to divide the outer sand mold into two pieces, which causes a problem that the number of so-called sand mold divisions increases. Moreover, because it is the way to mold the sand molds 1, 2, and 3 together, there is a large gap between the mating parts of the sand mold and the sand mold, and the molten metal insert fluid will flow into these In the gap, considerable burrs of inserts are caused, and the operation of removing these burrs of inserts is also quite troublesome and troublesome, and is also one of its disadvantages. In order to eliminate the above-mentioned shortcomings, it has been proposed in the past to use the "disappearing model" to carry out the method of making. According to this method, the foamed material is used to make the vanishing mold of the stator frame using a metal mold, and then the vanishing mold is placed in the casting box. In this state, the sand is placed in the casting box and beaten After hardening, the mounting solution is injected into the disappearing mold. In this way, the disappearing mold melts and disappears due to the high temperature of the wax liquid, and the casting liquid is filled into the cavity formed by the disappearing of the disappearing mold, thereby casting.

V. Description of the invention (3) According to this method, the positioning accuracy of the opening of the stator frame can be sufficiently improved because the metal mold is used to make the disappearing mold. The precision of manufacturing products). In addition, because the metal mold is clamped, the gap between the mold and the mold is relatively small, so the burrs generated by the disappearing mold become smaller, and the result is that the The burrs also become smaller. However, when the stator frame is built using the above-mentioned disappearing mold, because the protection member is a separate entity, the opening of the stator frame after the installation must still be bolted. The operation of fixing the protective member still has various disadvantages such as a large number of members and troublesome assembly. _ The object of the present invention is to provide a cast product and its binding method that can achieve the effect of improving the mounting accuracy of the inlaid product, reducing the flash of the flange parts, and reducing the number of components to improve the efficiency of assembly work. The casting product of the present invention belongs to a type of molded article in which a disappearing mold is installed in a casting box and sand is poured, and then casting liquid is poured into the disappearing mold to form, which is presumably equipped with the following components . This kind of component is made of non-disappearing material, and is fixed on the disappearing mold in such a way that a part of it protrudes, and when the inlay is injected into the disappearing mold, it can be sickled on the sickle integrally By. According to this method, the inlaid product of the present invention is formed by injecting a liquid of liquid into the disappearing mold, which not only improves the casting accuracy, but also reduces the burrs of the binding. And, by fixing a part made of non-disappearing material to the disappearing mold with a part of it protruding out, the structure is made (please read the precautions on the back before filling in this page). Binding- This paper uses the Chinese National Standard (CNS) A4 specifications (210x297 g; ¢) -5-199118 Λ 6 B6 Standard of the Ministry of Economic Affairs is the Inno V. Invention Description (4). It is included in the structure of the casting. In this way, not only can the number of components be reduced, but at the same time, it is no longer necessary to perform the installation work for mounting the components on the inlay, and the man-hour for assembly can be reduced. In the above-mentioned case, the conventional products refer to, for example, a frame for electrical equipment having an opening for ventilation; and a member refers to, for example, a protection member provided at both ends of the frame for electrical equipment. Furthermore, the protective member may also be composed of wire, net, or blinds. In addition, this component can also be used as a reinforcing member to prevent the deformation of the disappearing mold when sand filling is carried out in the casting box. In this situation, because the disappearing mold does not deform during sand removal, it can be more Definitely prevent the deformation or strength reduction of inlays. In addition, another form of the inlay device of the present invention is a device for placing a disappearing mold in the inlay box and filling it with sand, and then injecting a liquid of liquid into the disappearing mold to bind the inlaid product.

As a result, the positioning accuracy of the opening 11a in the stator frame 11 can be improved, and the burrs of the insert can be reduced. In addition, since the protective member 14 made of a non-erasable material is integrally cast at the position corresponding to the opening 11a in the disappearing mold 41, the number of members can be reduced and assembly can be reduced Working hours. However, in the conventional method, the protective member used for mounting in the opening of the stator frame mostly uses a porous plate made of plastic, which has the disadvantage that the strength of the protective member is weak. On the contrary, in the above embodiment, the protective member 14 is made of a plurality of metal rods 15 so that the strength of the protective member 14 can be increased. Furthermore, since the structure in which both ends of the plural metal rods 15 are embedded in the stator frame 11 is adopted, the stator frame 11 (please read the precautions on the back before filling in this page) Use the Chinese aa standard (CNS) Grade 4 standard (210X297 public waste) -18-193118 Shiyang standard of the Ministry of Economic Affairs, printed by the Industrial Consumers ’Cooperative Society ¾ 6 _____Bj6_ V. Description of invention (17) The strength can also be increased, the previous The common phenomena of the rotary motor, such as the falling off and damage of the protective member during the transportation process and the damage only after the rotary motor is installed, are no longer present in this embodiment. Furthermore, in the above embodiment. Because only the metal rod 15 is placed at the opening 1 1 a, the flow resistance of the air passing through the opening 1 1 a can be increased compared to the conventional configuration of a porous plate made of plastic The way of composition is smaller. Therefore, the exhaust efficiency of the cooling air can be better, and the cooling performance of the stator 12 can be improved. In addition, in the above embodiment, the coating mold is applied on the surface of the disappearing mold. Therefore, there is a coating mold layer between the stator frame 11 and the sand formed by the flange, which makes the stator frame 11 easier to remove the sand. Moreover, it is possible to easily carry out processes such as shot blasting for subsequent operations. Furthermore, according to the above embodiment, in addition to the vibration device 46, an auxiliary booster is added at the opposite position For the reason of the device 47, the vibration 43 can be applied to the sand 4 3 at any position in the box 4 2 by an auxiliary vibration device 47, so that the sand 43 around the disappearing mold 4 1 can be made The packing density is more uniform. In particular, the difference in the packing density of the sand 43 in the box 42 can be minimized, and the difference between the outer peripheral surface Sout and the inner peripheral surface S i η of the cylindrical disappearing mold 41 can be effectively reduced There is a pressure difference. As a result, the deformation of the disappearing mold 4 1 can be reduced, and the stator frame 11 which is a high-quality insert can be manufactured. Here, in order to confirm that the pressure difference between the outer peripheral surface S ut and the inner peripheral surface S i η of the disappearing mold 41 has a lowering effect, the pressure difference between the outer peripheral surface S ut of the disappearing mold 4 1 and The sand Ufc scale of the inner peripheral surface S i η uses the Chinese H Family Standard (CNS) A4 specifications (210X297) (Please read the precautions on the back before filling this page). -19-Shiyang Standard of the Ministry of Economic Affairs x, Jn Gongxiao Cooperative Co., Ltd. 51 199118 Λ 6 _; _ B 6_ V. Description of the invention (18) 4 3 The pressure distribution is measured. The results of this measurement are shown in Figure 11. In Fig. 11, the vertical axis represents pressure and the horizontal axis represents the distance from the vibration device 46. In this case, as shown in FIG. 7, a plurality of pressure sensors 57 are placed on the outer peripheral surface S out and the inner peripheral surface S i η of the disappearing mold 41 at regular intervals along the height direction Configure a distance. In the graph in Fig. 11, the white dots represent the measured pressure values on the outer peripheral surface S 〇 t; the black dots represent the measured pressure on the inner peripheral surface S i η. Incidentally, if the auxiliary vibration device 4 7 is not provided (that is, a conventional method), the measured effect acts on the outer peripheral surface S ut and the inner peripheral surface S i of the disappearing mold 41. The result of the pressure distribution on the sand 43 of η is shown in the 57th circle. It can be seen from the graphs in FIGS. 11 and 57. For example, in the graph in FIG. 11, it can be seen that the pressure pseudo tends to decrease as it moves away from the vibration device 46, compared with the graph in FIG. 57 , The pressure drop becomes smaller. Furthermore, as is clear from the results in FIG. 11, the pressure difference between the outer peripheral surface Sout and the inner peripheral surface 5 i η of the disappearing mold 41 is so small that it hardly exists. Moreover, in the case of the above-mentioned embodiment, although the auxiliary vibration device 47 is connected to other vibration sources not shown, it may be fixed integrally with the vibration device 46 in an integral manner On the side wall of the box 42. In addition, according to the above-mentioned embodiment, the strength to be buried in the shell forming portion 51 of the lost-type mold 50 is when manufacturing the lost-type mold 50 of the bearing bracket 16 The characteristic improving member 52 is made into a [thin wave band ^ sheet, so that the heat capacity of the strength characteristic improving member 52 becomes very small, and please (please read the precautions on the back and fill in this page) -20-199119

Figures 13 to 15 pseudo-represent the third embodiment of the present invention, Here, the differences from the first embodiment will be described. In Fig. 3, the stator frame 61 used to replace the previous stator frame 11 is formed with, for example, four openings 62 for ventilation in the peripheral wall portion. Of these, two openings 62 are arranged on the left and right of the upper part, and the other two openings 62 are arranged on the left and right of the lower part. The openings 6 2 are provided with blinds 6 3 made of non-disappearing materials as the blinds 6 3, which are composed of three elongated metal plates 64 for blinds arranged in parallel at specific intervals. Here, each shutter metal plate 64 is inclined as shown in Figure 13 so that when this motor is installed outside the house, if there is rain from above, rain water can hit the shutter 63. As a result, rainwater will not enter the stator frame 61 from the opening 62. The above-mentioned stator frame 61 is almost the same as that of the first embodiment, and it is made by using a disappearing mold. Here, Fig. 14 represents an intermediate metal mold 65 for forming a portion of the opening portion 6 2 of the disappearing mold. This intermediate metal mold 65 is composed of a gold mold that can be divided into two halves, that is, divided into intermediate metal molds 66 and 66. As shown in FIG. 15, a groove 66b for fitting and supporting the metal plate 64 of the shutter 64 is formed on the mold clamping surface 66a of the split intermediate metal mold 66 as shown in FIG. Insert the metal plate 64 for blinds into the groove 6 6 b of this split intermediate metal mold 6 6 (please read the precautions on the back before filling in this page). Thread · -22-199119 The standard of the Ministry of Economic Affairs is based on work Consumer Cooperative Yinyu Λ 6 Β 6 5. In the description of invention (21), the two split intermediate metal molds 6 6 are closed to form a complete intermediate gold lamination mold 65. Figure 14 shows the metal mold thus constructed. In this case, the two ends of the gold plate 64 for blinds protrude slightly from both end faces of the intermediate mold 65. Then, using the intermediate metal mold 65 described above, a disappearing mold was formed in substantially the same manner as in the first embodiment. At the opening of the formed disappearing mold, both ends of the gold plate 64 for coating mold are embedded and fixed, and a part of the metal plate 64 for shutters and the middle part protrude from the disappearing mold. Then, using such a disappearing mold, injection of the mounting liquid is carried out in substantially the same manner as in the above-mentioned first embodiment, that is, the stator frame 61 with the blinds 6 3 can be integrated with each other. In this third embodiment, in addition to obtaining substantially the same effect as the first embodiment, in particular, because the protective member is constituted by the louver 63, the position where the opening 62 is provided in the stator frame 61 is selected The degree of freedom can be expanded. As shown in FIG. 13, even if the opening portion 6 2 is arranged at the upper part of the stator frame 61, except when the horse is arranged outside the house, the shutter 63 can be used to prevent rain water from the opening portion 6 when it rains 2 intrusion. However, if only the net is used as a protection member, it is impossible to prevent rainwater from entering, and the opening cannot be arranged on the upper part. Therefore, according to the third embodiment described above, the opening 62, that is, the exhaust port can be provided at the most appropriate position, and it is possible to improve the cooling efficiency and use the cooling sucked from the intake port of the bearing bracket The wind effectively discharges the heat. As a result, the temperature of the stator and the central portion of the stator frame 61 can be lowered, and the temperature of the entire motor can be averaged and lowered to further improve the quality.
