Abstract
The present invention is to optimize the position of the metal plate to be installed in the bottom of the cooking vessel so that the cooking vessel can be used in the induction stove during the casting molding of the cooking vessel to improve the productivity of the induction stove cooking vessel To provide a manufacturing method.
The present invention is to support the lifting and lowering of the metal plate body exposed to the bottom surface by the cylinder during the molding molding of the cooking vessel recessed in the bottom of the cooking vessel so that the cooking vessel cast molded of aluminum material can be used in the induction stove It is supported by pins to optimize the position of the inside of the cooking vessel manufacturing mold to significantly improve product productivity.
Description
The present invention relates to a method of manufacturing a cooking container for an induction stove, and more particularly to cooking the position of the metal plate body is recessed to the bottom of the cooking container so that the cooking vessel cast molded of aluminum can be used in the induction stove. 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.
An object of the present invention is to provide a product that optimizes the position of the metal plate body exposed to the bottom surface of the cooking vessel is recessed in the bottom of the cooking vessel so as to be used in the induction stove cooker cast aluminum molded product It is to provide a method of manufacturing a cooking container for induction stoves to improve the productivity.
The manufacturing apparatus of the present invention for achieving the above object, the metal plate body and the metal plate body having the holes and the holes, and the protruding walls standing from the edges of the long holes and the cutting grooves are cut long outwardly from the center In the manufacturing apparatus of the induction stove cooking container made of a non-ferrous metal container body is filled with a high temperature solution between the holes and the holes and the cutting grooves of the metal plate to be recessed and exposed to the bottom surface. Mold to form a space for forming the container body to be cast; And installed at a lower end of the mold to protrude and elevate into the container body forming space formed inside the mold, and installed at the tip of the cylinder rod to support the metal plate horizontally in the container body forming space. The support plate is characterized in that it comprises a plurality of support pins installed at a predetermined interval along the circumferential direction.
The support pins are made of a diameter of 1mm ~ 4mm, the support pins are characterized in that consisting of 4 to 8 pieces.
The manufacturing method of the present invention for achieving the above object, the metal plate body and the metal plate body having a small hole and the long holes, the protruding walls and the cutting grooves are cut long in the center outward from the edge of the long holes A container formed inside the mold while being lifted by a cylinder installed below the mold for preparing a container so as to manufacture an induction stove cooking container which is recessed and exposed to the bottom surface. Providing support pins that can be positioned as a space for forming a body at regular intervals along the circumferential direction, thereby raising the support pins by the cylinder to be positioned in a space for forming a container body of the mold; Placing the metal plate horizontally on the support pins; A non-ferrous metal material is injected into the mold so that the solution is filled between the small holes, the holes and the cutting grooves so that the metal plate is integrated adjacent to the bottom face facing the induction stove. Casting the container body; Demolding the container body from a mold; And grinding the bottom surface of the container body so that a part of the metal plate is exposed to the outside to the bottom surface of the deformed container body, wherein the container body is manufactured. In the casting, the filling plate of the solution capable of maintaining the state where the metal plate is placed on the support pins is formed, and the support pins are lowered from the space for forming the container body of the mold by the cylinder. do.
The present invention is to be recessed in the bottom of the cooking vessel to be used in the induction stove cooking vessel cast molded of aluminum material to fix the metal plate exposed to the bottom surface with a plurality of support pins during the casting molding of the cooking vessel By optimizing its position, there is an effect of greatly improving product productivity.
