       The integrated wax injection machine is a key equipment used for low-temperature wax mold forming in the investment casting industry, with dual functions of stirring and wax injection. Here is a detailed introduction：
1.Structural composition
Wax storage bucket: Generally made of stainless steel material, it is used to store wax materials. For example, the wax cylinder volume of the MDYL-120 low-temperature wax injection molding machine is 120L, which can store a large amount of wax materials and is convenient for manufacturing large models.
Mixing system: composed of a motor, a mixing shaft, and a mixing blade. For example, the MDYL-120 type has a mixing speed of 860r/min, which can fully stir the wax material and make it more uniform.
Pneumatic system: including air compressor, air pressure pipeline, etc. Its function is to provide suitable injection pressure to the wax storage tank, ensuring smooth wax transportation and injection. The injection pressure of MDYL-120 type wax is 0.4MPa.
Electric heating temperature control system: composed of electric heating rods, temperature sensors, temperature controllers, etc., it can provide suitable temperature and heat to the wax material, so that the wax material is always in a suitable softening state. The temperature control range of MDYL-120 type is 30-80 ℃, and the heating power is 2 × 3kW.
Thermal insulation box: used to block the heat transfer between the electric heating temperature control system and the liquid heating box, ensuring the uniform temperature and heat required by the wax material, and reducing power consumption.
Wax conveying and injection device: including wax paste conveying pipeline, wax injection port, wax injection gun, etc., to transport and inject the wax material from the wax storage tank into the mold, so that the wax material eventually becomes a model.
2.Working principle
       After the device is started, the electric heating rod heats the water in the insulation tank. The hot water melts the wax material in the wax paste mixing tank, and the driving motor drives the mixer to rotate, causing the wax material to quickly melt and have a uniform density. The temperature sensor feeds back the temperature signal to the thermostat, which controls the operation of the electric heating rod to maintain a constant temperature. Turn on the air compressor to pressurize the wax paste mixing tank, creating a high-pressure state. Then, the melted wax material is injected from the wax injection port through the pressure and injected into the mold through the wax injection gun.
3.Characteristics
Accurate pressure and temperature control: equipped with pressure control device and heating control device, it can automatically adjust the pressure and temperature of the wax cylinder, so that the mold material is always in an ideal state, making it easy to produce high-quality models.
High safety performance: equipped with safety protection devices, when the pressure exceeds the rated pressure, the safety protection devices can work to avoid accidents.
High efficiency: The wax cylinder has a large volume, and the dual stations are relatively independent and do not affect each other. They can be operated simultaneously or separately, which is convenient to use and can improve production efficiency.
Advanced pneumatic system: using domestically advanced manual directional valves, oil and air filtration devices, and plug-in quick couplings, easy installation, easy pipe replacement, reliable sealing, firm and beautiful connections, and long service life.
Easy to operate: The wax injection head is manually controlled, easy to operate, and flexible to maneuver. It is equipped with a micro muffler and flow control valve, with low noise, adjustable flow rate, and adjustable control of operating speed.
