Technical Field
The utility model belongs to the technical field of half solid-state magnesium alloy processing, specific saying so relates to a half solid-state magnesium alloy injects electromagnetic heating device.
Background
At present, semi-solid magnesium alloy products are mainly produced by matching an injection molding machine with a mold.
The semi-solid magnesium alloy injection molding has incomparable advantages of other casting methods, such as energy saving (the melting temperature of the magnesium alloy is low: the magnesium alloy is required to be heated to 650-680 ℃ in the general magnesium alloy casting, and the magnesium alloy is required to be heated to 580-600 ℃), environmental protection (no protective gas is required: SF6 and other protective gases harmful to the environment are required to prevent the magnesium alloy from being oxidized and burnt after the magnesium alloy is melted in the general magnesium alloy casting, the molten magnesium alloy is not contacted with the air in the injection molding process), safety (although the protective gas is used after the magnesium alloy is melted in the general magnesium alloy casting process, the risks of spontaneous combustion and explosion still exist, the molten magnesium alloy is in a closed container which is not contacted with the air in the injection molding process, and the risks of spontaneous combustion and explosion are avoided).
However, the semi-solid magnesium alloy forming machine generally adopts resistance wires to heat the outer surface of the material pipe, and the magnesium alloy raw material in the material pipe is subjected to heat conduction through contact, so that the heat conduction efficiency is low, the melting time is long, and the production beat is slow.
Disclosure of Invention
In order to overcome the defects, the utility model provides a half solid-state magnesium alloy injection electromagnetic heating device, can be rapid with heat conduction for magnesium alloy raw and other materials, shortened production time, improved production efficiency greatly.
The utility model discloses a solve the technical scheme that its technical problem adopted and be: a semi-solid magnesium alloy injection electromagnetic heating device comprises a screw, an electromagnetic heater, a temperature sensor, heat-preservation cotton and a material pipe, wherein the screw is arranged in the material pipe and can rotate along the axis of the material pipe relative to the material pipe; the heat preservation cotton is wrapped in the periphery of material pipe, electromagnetic heater locates the periphery of heat preservation cotton.
As a further improvement, the material pipe is also provided with a plurality of temperature sensors, and the temperature measuring head of the temperature sensor extends into the material pipe.
As a further improvement of the utility model, a plurality of temperature sensor evenly distributed in on the material pipe.
As a further improvement, the front end of the material pipe is provided with a material spraying port, and the screw head of the screw rod is correspondingly arranged in the material spraying port.
As a further improvement, the front end radius of the material spraying opening is gradually reduced.
The utility model has the advantages that: this half solid-state magnesium alloy injection electromagnetic heating device is through setting up electromagnetic heating system, and the shortening that can be quick melts the material time, reaches the effect of melting the material fast, and the cotton can protect electromagnetic heating system and heat preservation effect of keeping warm simultaneously to can shorten the production beat greatly, improve production efficiency.

Detailed Description
The following description of the preferred embodiments of the present invention will be made in conjunction with the accompanying drawings.
Referring to fig. 1, the electromagnetic heating device for semi-solid magnesium alloy injection according to the present invention comprises a screw rod 1, an electromagnetic heater 2, a temperature sensor 3, a thermal insulation cotton 4 and a material pipe 5, wherein the screw rod 1 is arranged in the material pipe 5 and can rotate along the axis of the material pipe 5; the heat preservation cotton 4 wraps the periphery of the material pipe 5, and the electromagnetic heater 2 is arranged on the periphery of the heat preservation cotton 4.
In order to facilitate the real-time inspection of the temperature of the material, a plurality of temperature sensors 3 are further arranged on the material pipe 5, and temperature measuring heads of the temperature sensors 3 extend into the material pipe 5. In order to heat evenly, a plurality of temperature sensors 3 are evenly distributed on the material pipe 5. The front end of the material pipe 5 is provided with a material spraying opening 51 with the radius of the front end gradually reduced, and the screw head 11 of the screw is correspondingly arranged in the material spraying opening 51.
This half solid-state magnesium alloy injection electromagnetic heating device at during operation, at first start the stirring screw rod, then start the quick feeding pipe of electromagnetic heater and arrange the interior raw and other materials heating of charging pipe in, the raw and other materials in the charging pipe under the stirring effect of screw rod, thermally equivalent reaches the molten condition fast, and temperature sensor can the real-time detection material the temperature, can jet out half solid-state magnesium alloy thick liquid through the screw rod head when reaching preset temperature. Wherein, the cotton cover of heat preservation is in the material pipe periphery, protects electromagnetic heater, plays fine heat preservation effect to raw and other materials simultaneously.
Therefore, the semi-solid magnesium alloy injection electromagnetic heating device can rapidly shorten the material melting time by arranging the electromagnetic heating system, achieves the effect of rapidly melting materials, and can protect the electromagnetic heating system and the heat preservation effect by the heat preservation cotton, so that the production beat can be greatly shortened, and the production efficiency is improved.
