Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] This embodiment provides an injection-type quantitative furnace for an induction heating magnesium alloy without a check valve, such as figure 1 As shown, the injection-type dosing furnace includes a furnace body 104, a feeding pipe 101, a cylinder 102, an injection dosing pot 103 and a dosing furnace outlet 105, and the cylinder 102 is a small cylinder with adjustable stroke.
[0033] Among them, such as figure 1 with 2 As shown, a crucible 201 is arranged in the furnace body 104, and the crucible 201 is connected with the injection dosing pot 103. The crucible 201 is gravity casted by qualified nickel-free high-temperature steel, with a wall thickness of 30mm, and can be used normally for 15 months; The crucible 201 is provided with SF6+N2 shielding gas, and a material leakage protection plate is used on the bottom of the shelf of ...

Abstract
The invention discloses an induction-heating-type magnesium alloy injection quantitative furnace without a one-way valve. The furnace comprises a furnace body, a crucible arranged in the furnace body and a conveying pipe and further comprises an injection quantitative material kettle connected with the crucible. The injection quantitative material kettle is provided with a hanging table, a quantitative material pipe and a discharge port, and a plurality of feed openings are formed in the quantitative material pipe. The hanging table is fixedly installed with an air cylinder support and the discharge port is communicated and fixed with the conveying pipe. The injection quantitative material kettle can conduct quantitative injection, and is applicable to products with the pouring amount lower than 200 g. Thus, no expensive one-way control valve device which is prone to abrasion exists, accurate quantitative output is completed by using the volume difference, and the induction-heating-type magnesium alloy injection quantitative furnace is simple and reliable in structure and low in cost.
Description
technical field [0001] The invention relates to magnesium alloy die-casting equipment, in particular to an induction heating magnesium alloy injection-type quantitative furnace without a check valve. Background technique [0002] In the prior art, magnesium alloy die-casting methods are divided into hot chamber die-casting and cold chamber die-casting. Hot chamber die-casting is used under high temperature and high pressure for hot parts such as material pot and nozzle body, so it needs to be made of expensive special steel, and the cost is high. And it is easy to wear and damage. At present, magnesium alloy hot chamber die-casting requires manual operation and has not realized automatic production. The number of workers required is high, the temperature of the production site is high, the conditions are poor, the workers are tired, the turnover rate of workers is high, skilled workers are difficult to recruit, and the labor cost is high. [0003] Magnesium alloy cold chamb...
