The working MASTERplastic injection toy mould

The working principle of mold temperature machine consists of a water tank, heating and cooling system, power transmission system, the liquid level control system and a temperature sensor, MASTER plastic injection mould port devices. Usually, power transmission system in the pump so that the thermal fluid from the tank is equipped with a built-in heater and cooler to die, then die from the back to the water tank; temperature sensor to measure the temperature of hydrothermal fluids and transmit data to the control part of the controller; the controller adjusts the hydrothermal temperature, thereby indirectly control the mould temperature. If the mold temperature MASTER injection molding suppliesmachine in production, mold temperature exceeds the set point of the controller, the controller will open the electromagnetic valve is communicated with a water inlet pipe, until the heat fluid temperature, the mold temperature to the set point. If the mold temperature is lower than the set value, the controller will turn on the heater.

Preparation conditions MASTER plastic rattan garden furniture system to control the mold temperature

Preparation conditions of temperature control system control mold temperature, mold temperature machine, the mold heat transfer fluid is composed of three parts. In order to ensure that heatMASTER pe pipe fitting mold can be added to the mold or moved, each part of the system must meet the following conditions: the first is in the mold, cooling channel surface area must be large enough, the ability to channel diameter to match the pump (pump pressure). The temperature distribution in the cavity on the deformation and internal pressure have a great impact. A reasonable set of cooling channel can reduce the internal pressure, so as to improve the quality of injection molded parts. It also can shorten the cycle time, reduce product cost. The second is the mold temperature machine must be able to keep constant temperature heat conducting fluid in the range of 1 ℃ -3 ℃ within, depending on the product MASTER zplastic box moldquality requirements set. Third is a heat transfer fluid must have good heat conduction ability, the most important is, it must be able to import or export a large amount of heat in the shortest amount of time. From the thermodynamic point of view, the water is more obvious than that of oil well.

Metal mold cavity surface thermal fatigue

Cavity surface metal thermal fatigue ( cracking ) . Hot mold work is characterized by intermittent . After each state of the metal forming the hot water to be cooled cavity surface oil, air and other media. Therefore . Hot mold working condition is repeated heating and cooling , so that the surface of the metal mold cavity to produce plastic container moldingthermal expansion and contraction , which repeatedly subjected to tensile and compressive stress . As a result, the cavity caused by surface cracks , called thermal fatigue phenomenon whereby hot die steel made for second basic performance requirements. That has a high thermal fatigue resistance . In general, the factors affecting the thermal fatigue resistance of steel are mainly : ① steel thermal conductivity. The high thermal conductivity of steel , a metal mold can reduce the degree of surface heating , thereby reducing the tendency of the steel to thermal fatigue . Thermalconductivity is generally believed that the amount of carbon steel and cooperation related to the high china plastic injection moldingthermal conductivity when the carbon content is low, it should not be hot die steel with high carbon steel. Commonly used in the production of carbon steel (C0.3% 5 ~ 0.6%) combined carbon content is too low. Causes decrease in the hardness and strength of steel .Isdisadvantageous.Critical point ② Steel. The critical point is usually steel (Acl) is higher. The lower steel thermal fatigue bias. Therefore . Usually by adding alloying elements Cr, W, Si, attracted improve the critical point of the steel. Thereby improving the thermal fatigue resistance of steel.
