The present invention relates to a method of manufacturing a cooking container for an induction stove which is optimized at the time of casting molding of a container to improve product productivity.

Induction ranges generally have a built-in coil for generating a magnetic field when a high voltage is applied to the induction range, and such an induction range induces a magnetic field when a high voltage is applied to the coil. The principle is that the metal is heated.

These induction stoves do not generate any flame or harmful gas, so there is no danger of fire, and there is no carbon monoxide inevitably generated when gas is used as a heat source. have.

Induction stoves do not cause burns even when the grille is touched while the container is heated.There is no spark, so there is no risk of fire or explosion, and the body does not burn even when the grille is touched while the power is on. It has been used a lot recently.

However, a container for use in such an induction stove must be made of metal with the bottom surface of the container, which is the part touching the grille, to be magnetically induced by the magnetic field generated by the induction stove. That is, the bottom surface of the cooking vessel should contain iron (Fe).

Therefore, the induction stove can be used only a container made of a magnetic material and a magnetic sensitive metal, a container made of stoneware and ceramics or a container made of a non-ferrous metal such as aluminum or stainless steel that occupies most of the cooking vessel. This is an impossible drawback.

In general, a cooking vessel (pot, frying pan, kettle, pressure cooker, etc.) usable in the induction stove is attached to a conductive metal plate on the bottom surface of the container body of the non-ferrous metal. In other words, the container that can be used in the induction stove is made of a non-ferrous metal and a different material of the metal material.

Such a container can be produced by welding a different material, but it is manufactured by casting molding for mass production simply, but it is difficult to fix the position of the metal plate in a suitable state during casting molding, so that a lot of defective products are produced. In addition, there is a problem that the metal plate is deformed due to the heat of the metal material when the non-conductive metal material is injected.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In order to manufacture the cooking container for the induction stove according to the present invention, firstly provided with small holes (214) and long holes (212) and protruding walls (216) laid from the edge of the long holes (212) and from the center toward the outside The metal plate body 200 having the cutting grooves 222 long cut.

3 to 6, the metal plate 200 is made of a conductive metal material and formed by the container manufacturing mold 400 (see FIGS. 7 to 9). Installed in recessed. At this time, the metal plate 200 is installed to be exposed to the bottom surface of the container body 100, as shown in Figure 1 to 2 in response to the magnetic field generated in the induction stove and the contents contained in the container body 100 Allow to cook.

The long holes 212 include a radially extending from the center of the metal plate 200 and arranged to bend inwardly of the metal plate 200 therebetween, the small holes 214 are the holes 212 It is formed evenly arranged between them. It is preferable that the diameter of the small holes 214 has a degree of about 3 to 8 mm, and when the diameter of the small holes 214 is large, the metal plate body 200 and the container body 100 of a nonferrous metal (aluminum) having different materials are used. This is because the bonding force is lowered and the diameters of the small holes 214 are not good because the material of the container body 100, which is a different material from the metal plate body 200, does not pass. By allowing the material of the container body 100 to pass through the small holes 214 to maintain a firm bonding force, the metal plate 200 can be firmly recessed in the container body 100 integrally.

The metal plate 200 may be installed on the container body 100 such that the protruding wall 216 formed from the edges of the long holes 212 is exposed from the bottom of the container body 100, and the protruding wall ( 216 may be installed on the container body 100 so as not to be exposed to the outside. In the former case, the protruding wall 216 serves to react with the magnetic field generated in the induction stove, and in the latter case, the protruding wall ( 216 increases the coupling surface with the container body 100 so that the metal plate 200 can be firmly installed on the container body 100 of aluminum material. In particular, in the former case, the protruding wall 216 facilitates the processing of the bottom surface of the container body 100 after molding the container body 100.

In addition, the cutting grooves 222 deform the metal plate 200 due to the heat of the solution during the casting molding for forming the container body 100 after placing the metal plate 200 in the mold 400. To prevent it. The cutting groove 222 is preferably formed by cutting the edges of the long holes 212 extending radially from the center of the metal plate 200. The outer peripheral surface end of the metal plate 200 has a predetermined tension by the cutting grooves 222, because of this, the metal plate 200 by the heat of the solution injected during the molding of the container body 100 It stays horizontal without being deformed.

Meanwhile, as shown in FIGS. 7 to 9, the mold 400 for casting the container body 100 includes an upper mold 400a and a lower mold 400b, and the fixed lower mold 400b is formed. The upper mold 400a is moved upward and downward from the upper side to form the container body 100. Reference numeral 401 denotes a molten metal injection hole formed in the upper mold 400a in contact with the space for forming the container body 100 formed between the upper and lower molds 400a and 400b. .

In addition, a cylinder 302 is installed at the lower center portion of the lower mold 400b, and the metal plate body 200 is formed in the space 402 for forming the container body 100 at the tip of the rod 304 of the cylinder 302. Support pins 300 are installed to fix and support the position of the support pins 300 so that the support pins 300 are lifted up and raised in the forming space 402 by the cylinder 302.

As such, the metal plate body 200 and the support pins 300 capable of supporting the metal plate body 200 are introduced into the mold 400 by the cylinder 302 provided under the mold 400. When installed in the elevated state, as shown in FIG. 8 by the cylinder 302 so that the upper end of the support pins 300 protrude in the upper portion of the lower mold 400b in the state where the upper mold 400a is opened. As the metal plate 200 is raised, the metal plate 200 is placed on the supporting pins 300 to be level.

Thereafter, as shown in FIG. 9, the lower mold 400b is covered with the upper mold 400a. In this case, the metal plate 200 supported by the support pin 300 is the container body 100. It can be seen that the upper portion of the portion of the space 402 forming the bottom of the). That is, it can be seen that the metal plate 200 is optimally positioned adjacent to the bottom surface of the container body 100 facing the induction stove.

In addition, the diameter of the support pins 300 in the space 402 of the mold 400 so that the metal plate 200 can be located adjacent to the bottom surface of the container body 100 facing the induction stove. If it can support the diameter is good to form a sufficient 1mm ~ 4mm. Reference numeral 306 denotes a support plate installed at the tip of the cylinder rod 304 to allow the support pins 300 to be arranged in the circumferential direction.

As shown in FIG. 11, the support pins 300 have a function for fixing the position of the metal plate 200 in the space 402 of the mold 400. They protrude into the space 402 of the mold 400 and are installed at regular intervals along the circumferential direction so as to easily support the metal plate 200.

12A to 12C, the support pins 300 are circumferentially supported on the support plate 306 installed at the tip of the rod 304 of the cylinder 302 so that the metal plate 200 can be horizontally supported. It is good to be arranged in a position at a predetermined interval along the direction. That is, the support pins 300 may be installed in a number of four, six, eight, which are arranged at uniform intervals along the circumferential direction, but the number is not limited thereto, and the metal plate 200 is horizontal. It can be a number that can support to achieve.

As shown in FIG. 9 in the state in which the metal plate 200 is horizontally supported by the support pins 300 as shown in FIG. 9, the non-ferrous metal of the high temperature through the hot water 401 inside the mold 400. When the phosphorus aluminum solution L is injected, the aluminum solution L is filled between the small holes 214 of the metal plate 200 and the holes 212 and the cutting grooves 222, and the filling is completed. The support pins 300 are lowered by the cylinder 302 to exit the space 402 of the mold 400.

At this time, the metal plate 200 does not sink and maintains the same state as the state placed on the support pins 300, for this reason, as shown in FIG. Even if it descends from the space 402 of), since the metal plate 200 receives the filling pressure as indicated by the arrow of FIG. 10 from the aluminum solution L for casting the container body, the metal plate 200 is The same state as the state laid on the support pins 300 is maintained without being submerged and is embedded in the bottom portion of the container body 100 formed by the aluminum solution.

When the container body 100 of the cast aluminum material is demoulded from the mold 400, the metal plate 200 is completely formed at the bottom of the container body 100, as shown in FIGS. 1 and 2. It can be seen that the horizontal state is achieved, even if the bottom surface of the container body 100, that is, a little polishing the bottom surface facing the induction stove can be seen that the metal plate 200 is easily exposed. As a result, the defective rate of the product is remarkably reduced, so that the productivity is greatly improved, and the polishing operation for exposing the metal plate 200 from the bottom surface of the container body 100 becomes very easy.
