preparation example Construction

[0020] Such as figure 1 As shown, it is a schematic flow diagram of a method for preparing an oven food mold in a preferred embodiment of the present invention, and a method for preparing an oven food mold is provided, comprising the following steps:

[0021] a. Kneading the silicone rubber compound with a rolling mill;

[0022] b. Add oxides and pigments as vulcanizing agents, blend them and take them out of the rolling mill;

[0023] c. molding the obtained mixture by extrusion molding or injection molding.

[0024] First, use a rolling mill to knead the silicone rubber compound. The silicone rubber contains one of silicone oil or food oil. It is a silicone rubber with a JIS A hardness of 55-95 and a thermal conductivity of 0.15-0.50W / m.℃. Silicone rubber is mixed with fiber filler so that the elongation at break is reduced to 10-100%, then oxides and pigments are added as vulcanizing agents, blended and taken out of the rolling mill, and the resulting mixture is extruded ...

Embodiment 1

[0029] The siloxane compound is kneaded with a rolling machine. During the kneading process, 20 parts of quartz powder are added and kneaded to obtain the silicone rubber compound. Add oxides and pigments as vulcanizing agents, 2 parts by weight of silicone oil to 100 parts by weight of silicone rubber compound, and extrude at 170° C. for 10 minutes to prepare a circular oven food mold, and then two at 200° C. After 4 hours of secondary vulcanization, it can be made into oven food molds. The prepared oven food mold has the following physical properties: JIS A hardness is 75, thermal conductivity is 0.25 W / m.°C, and elongation is 45%. Put the bread ingredients into the oven food mold and bake at 230°C for 10 minutes, no deformation occurs, and the baked bread is very easy to demould.

Embodiment 2

[0031] Knead the siloxane compound with a rolling mill, add 15 parts of diatomaceous earth during the kneading process, and knead to obtain the silicone rubber compound. To 100 parts by weight of the silicone rubber compound, add oxides and pigments as a vulcanizing agent, 3 parts by weight of food oil, mix vinyl-containing polydimethylsiloxane and organohydrogenpolysiloxane to obtain a liquid mixture, and simultaneously The liquid mixture is injected into a star-shaped metal mold through an injection molding machine, extruded at 180°C for 8 minutes to prepare a star-shaped oven food mold, heated at 160°C for 1 minute, and the formed oven food mold Take it out, and then perform secondary vulcanization at 200°C for 4 hours to make an oven food mold. The prepared oven food mold has the following physical properties: JIS A hardness is 70, thermal conductivity is 0.20 W / m.°C, and elongation is 230%. Put the bread raw materials into the oven food mold and bake it at 230°C for 20 m...

Abstract

The invention discloses a method for manufacturing an oven food mould, which comprises the following steps of: a, kneading silicon rubber compound by using a roll mill; b, adding oxides and pigments serving as vulcanizing agents, blending, and taking the obtained product out of the roll mill; c, molding the obtained mixture by an extrusion molding method or an injection molding method. The oven food mould manufactured by the method is mainly used for baking cakes. The mould has the advantages of excellent durability and heat resistance and good demoulding property, and oil or grease or a layer of release paper does not need to be brushed or laid on the inner surface of the mould; in addition, bread raw materials containing lot of sugar and eggs can be easily broken away from the mould after baking.

Description

technical field [0001] The invention belongs to a mold, in particular to a method for preparing a food mold for an oven. The mold made by the mold is more suitable for baking bread and the like. Background technique [0002] The so-called molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, casting, forming, smelting, stamping, stretching and other methods to obtain the required products. In short, a mold is a tool used to shape an item. The level of mold technology is an important symbol to measure the level of manufacturing industry. [0003] Bread with a specific shape is usually prepared by packing bread raw materials into a mold with a specified shape and baking. Generally, a metal mold is used as a mold for baking bread. The metal mold is made by processing the metal plate to make it have a specific shape. In practical application, a layer of oil or grease will be brushed on the inner surface of the metal mol...
