Abstract

The utility model discloses a compound end cast iron pot, compound end cast iron pot bottom has the type groove of the semi-surrounding tenon fourth of the twelve earthly branches structure of constituteing by cast iron pot outer bottom and type limit and type post, and the type groove can be accomplished with the integrative casting of the cast iron pot body, perhaps casts earlier when casting with the integrative casting of the cast iron pot body into the groove base and forms the type groove through processing again, uses the type groove as mould partly and suitable mould group die cavity, goes into the die cavity with the pouring of molten aluminium liquid, forms composite aluminum plate after the aluminium liquid solidifies, accomplishes the preparation of compound end cast iron pot. The composite bottom cast iron pot has the advantages that the composite surface is tightly attached, the heat conduction effect is good, and the composite bottom cannot crack or fall off when the composite bottom cast iron pot is cooked and heated.

Description

Composite bottom cast iron pot

Technical Field

The utility model belongs to the technical field of cooking utensil and preparation thereof, a cast iron pan at compound end is related to, especially relate to a cast iron pan at compound end.

Background

Pans are cooking utensils frequently used by people, pans made of cast iron, aluminum and aluminum alloy (hereinafter, collectively referred to as aluminum) are commonly used by people, cast iron pans (hereinafter, referred to as cast iron pans) are more beneficial to health of people due to the characteristic that the cast iron pans do not select a slice, but the cast iron pans with the same thickness have lower heat conduction uniformity than aluminum pans (hereinafter, referred to as aluminum pans) due to the fact that the cast iron heat conduction efficiency is far lower than that of aluminum, the heat conduction uniformity of cast iron pans can cause local overheating of the cast iron pan bottom, oil smoke is generated, the environment is influenced, the health is not facilitated, if the heat conduction uniformity of cast iron pans is improved, the thickness of cast iron pan bottoms can be increased, but the weight is greatly increased, the inconvenience is brought to use, the aluminum pans have high heat conduction efficiency, good heat conduction uniformity, small density, light weight and convenient use, and are also favored by people due to the fact that aluminum is softer, the used turner is limited to a certain extent, and the aluminum pot is used for cooking certain foods and causes worry to health increasingly, so people develop various composite bottom cast iron pot manufacturing technologies for compounding an aluminum plate at the bottom of the cast iron pot in order to fully utilize the cast iron pot to be beneficial to health without selecting the characteristics of good heat conduction uniformity, small density and light weight of the turner and the aluminum pot, but the currently developed composite bottom cast iron pot manufacturing technologies realize the compounding of the cast iron pot and the aluminum plate by using a method of welding or riveting rivets distributed at the bottom, the composite bottom cast iron pot is an appliance used for heating, metal materials can generate thermal expansion when being heated, the thermal expansion can generate deformation when being blocked and restrained, and the cast iron pot and the aluminum plate can generate thermal expansion along the direction of a compounding surface by using a welding or riveting method because the thermal expansion coefficients of cast iron and aluminum are greatly different, due to different expansion coefficients, the aluminum plate is restrained and hindered by welding or riveting, so that the deformation of the aluminum plate is caused, the heat conduction effect is reduced, and even the aluminum plate is cracked or falls off. For example, in the pot with a composite bottom disclosed in chinese patent document CN201894562U, in the technical scheme, the bottom of the pot body is provided with the composite bottom, the composite bottom comprises a heat conduction layer and a bottom layer, the heat conduction layer is provided with through holes, the bottom layer is provided with protrusions, the protrusions penetrate through the through holes of the heat conduction layer and are connected with the bottom of the pot body in a welding manner, the heat conduction layer can enable the pot body to be heated uniformly, the occurrence of local high temperature is effectively inhibited, and therefore, the. According to the technical scheme, the protruding parts are equivalent to rivets, the combination is riveting of the rivets, and due to the fixing effect of the distributed protruding parts, the expansion of the heat conduction layer along the direction of the combination surface is hindered during heating, so that the heat conduction layer is deformed, the heat conduction effect is reduced, and even cracking and falling occur. In practice, if more than two rivets are connected to the composite base, the heat conducting layer will expand and deform between the riveting points when heated.

Disclosure of Invention

The utility model aims to provide a composite bottom cast iron pan, which aims to solve the problem that the composite bottom of the composite bottom cast iron pan is easy to crack and fall off, and the composite bottom cast iron pan (with a pan wall or without a pan wall) is characterized in that the outer bottom of the composite bottom cast iron pan is a type groove with a semi-enclosed tenon-and-mortise structure, which consists of an outer bottom of the cast iron pan, a section edge and a section column, the section edge is a surrounding edge on the circumference of the outer bottom of the cast iron pan, the section column is a columnar body on the center of the outer bottom of the cast iron pan, the type groove is formed by integrally casting with the cast iron pan body, or a groove blank is formed by casting together with the cast iron pan body through processing, the type groove can be a dovetail type groove outer bottom, a T type groove or a type groove with other shapes, which forms a semi-enclosed tenon-and-mortise structure through the outer bottom of the cast iron pan and the section column, an, the aluminum plate in the composite bottom cast iron pot groove is formed by pouring molten aluminum liquid into the groove and solidifying the molten aluminum liquid in the groove, so that the limit state of the thermal expansion of the aluminum plate when the composite bottom cast iron pot is heated is the state of beginning solidification during pouring, the expansion of the aluminum plate is not hindered when the composite bottom cast iron pot is heated, and the problem that the heat conduction effect is reduced due to deformation and even cracking or falling is avoided.

Drawings

FIG. 1 is a sectional view of a composite bottom cast iron pan, the section passes through the diameter of the pan bottom and is vertical to the plane of the pan bottom, in FIG. 1, 1 is a cast iron pan body, 2 is a profile edge, 3 is a profile column, 4 is the outer bottom of the cast iron pan, 5 is a groove, and 6 is an aluminum plate.

Detailed Description

In the embodiment, the half-surrounded mortise-tenon structural type groove of the composite bottom cast iron pan can be various, in the embodiment, the type groove (5) consists of a dovetail-shaped edge (2), a dovetail-shaped column (3) and an outer bottom (4) of the cast iron pan, the type groove (5) and the cast iron pan body (1) are cast integrally, or when the type groove (5) and the cast iron pan body (1) are cast integrally, a groove (5) blank is cast and formed firstly, then the type groove (5) is processed to form the type groove (5), the type groove (5) is subjected to rust removal treatment, the cast iron pan body (1) is heated to the temperature which is the same as the liquid phase of aluminum to be cast, the type groove (5) is used as a part of a mold to form a molten aluminum liquid cavity together with a proper mold, molten aluminum liquid is poured into the type cavity from a pouring port, the molten aluminum liquid is solidified to form an aluminum plate (6.
