Description

Self-preheating mold

Technical Field

The utility model belongs to the technical field of dies, and particularly relates to a self-preheating die.

Background

In the process of using different molds to perform material molding processing on high-temperature materials, such as liquid metal materials, softened glass materials, thermoplastic resins and the like, cold molds are generally directly used for replacing production lines, and hot materials are processed. However, the material is easy to cause the material performance changes such as expansion with heat and contraction with cold due to the rapid change of the temperature, so that the produced products can not reach the standard within a long time period after the die is replaced, and the rejection rate is greatly improved. When the mould is heated to a temperature close to the hot material, the product can be effectively produced. Many enterprises adopt a mould preheating procedure, and a method of putting a mould into a preheating furnace such as a coal furnace, an electric furnace and the like in advance for heating or using a gas fire gun to spray fire and heat the mould is adopted to reduce the rejection rate. However, the preheating furnace or the flame gun still needs to be heated for a long time, so that the energy consumption is high after long-term use, and the production cost is increased.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1-3, a self-preheating mold comprises a covering shell 1, a cavity 2 is arranged inside the covering shell 1, a mold 3 is installed in the cavity 2, the mold 3 is fixedly connected to the inner wall of the covering shell 1, a heating device is further arranged in the cavity 2, a pouring pipe 4 is further included, and the pouring pipe 4 penetrates through the covering shell 1 and extends to a pouring opening of the mold 3 in the cavity 2. The self-preheating mould provided by the technical scheme preheats the mould in an internal heating mode, and the mode realizes self-preheating, so that compared with a method for preheating the mould in a preheating furnace such as a coal furnace, an electric furnace and the like in advance or heating the mould by using a gas fire gun to spray fire, no intermediate step exists, the mould cannot dissipate heat in the intermediate step such as the mould is transferred from the preheating device, the mould preheating efficiency is improved, and the production period is shortened; and energy consumption can be saved.

Heating device includes jet-propelled pipe 5, a plurality of air jets 6 have been seted up on jet-propelled pipe 5, jet-propelled pipe 5 still communicates there is air supply pipe 7, the external air feed of air supply pipe 7, still install a plurality of cooperation air jets 6 on the jet-propelled pipe 5 and some firearm 8, exhaust gas discharge port 9 has been seted up on the cladding shell 1. When specific air supply pipe 7 supplies with the gas, utilize some firearm 8 to ignite and realize in the cladding shell 1 to mould 3 heating, owing to there is cladding shell 1 on the one hand can reduce the heat of heating in-process and scatter and disappear, on the other hand when air supply pipe 7 is connected the fan and is supplied with the natural wind, spun air can be to mould 3 cooling down in the jet-propelled pipe 5 to help accelerating the cooling process after accomplishing to pour.
