To reduce the flow resistance, flow passage all intersections are turning should be smooth transition.
In addition, because of the melt in the runner after downtime will be all set, so on the axis of the shunt way should be set to quick opening and closing of parting surface, in order to thoroughly remove all setting before starting the next time.
The mainstream way type gate adiabatic flow channel the beginning of the injection mold gate upward and protruding into the focus of distributary channel.
The adiabatic flow channel is only applicable to molding cycle is short, the disadvantage is that the injection molding processing parts still carry a short passage setting material, must be in the process of removal.
no flow channel without waste processing basic implementation, greatly save raw materials, saves the work out port setting during the process of injection molding materials, simplify the operation, to realize automatic production. Open mould and mould clamping stroke at the same time can be shortened, so as to shorten the molding cycle, improve the labor productivity. No flow saves excision, crushing and recovery of condensate such as pieces of plastic material and repair work, helps to save manpower, reduce equipment, reduce the cost. At the same time no longer use after repeated injection molding of plastics processing and may degrade or stained with impurities flow condensation, thus beneficial to improve the quality of plastic parts.
no runner injection mold structure is complex, but need to have a special nozzle and temperature adjusting device, thus the manufacturing cost is higher. As a result, its information used for high quality requirements, the production batch larger plastic molding. Plastic to keep the molten state method based on the flow passage is different, there is no port condensate injection mold material divided into two major categories of adiabatic flow injection mold with hot runner injection mold, and in each category and there are several different types of structure.
adiabatic flow characteristics of injection mold is the mainstream of the mould and distributary channel are very bulky, allowing molten plastic can pass it smoothly into the cavity, to achieve continuous injection without having to take out the port setting material requirements. Adiabatic flow injection mold can be divided into well type nozzle injection mold and two adiabatic flow of multi-cavity injection mold. Well type nozzle injection mold is also known as adiabatic mainstream way injection mold, it is one of the most simple in adiabatic flow injection mold, suitable for monotype modes.
monotype modes of mould is according to the characteristics of the parts with the entrance of the injection molding machine nozzle and mold a mainstream word cup, cup have hold the molten plastic shaft pit. In injection molding process, in addition to the lateral was soon condensation, can always stay near the center of the molten state, make the melt from the cylinder to continue through the flow into the cavity. In order to keep the sprue cup near the center of the melt condensation, injection molding machine nozzle and the sprue cup well pit should always close contact.
no port setting material injection molding processing module is by using the method of heating or thermal insulation, made from injection molding machine nozzle to cavity entrance this plastic has maintained the molten state of a port, thus need to take out the plastic parts when open mold, no need to remove the port setting material of a plastic injection mold. With no port setting material is plastic molding process of injection moulds to develop in the direction of energy saving, low consumption, high efficient processing of a major reform. In the whole process, because the plastic keeps molten state of gating system, so the pressure loss is small, can realize the gate, the multi-cavity mold and large low pressure injection molding of plastic parts. As well as to pressure transmission, can overcome the shrinkage due to lack of fill material dent, improve the quality of the plastic parts.
adiabatic flow of multi-cavity injection mold is also known as adiabatic flow injection mold. The multi-cavity injection mold according to its different gate adiabatic flow path, can be divided into the mainstream type gate and gate two types. The adiabatic principle of the mould is the same as well type nozzle injection mold, the mainstream way and distributary channel are very bulky, cross section shape is often circle. The diameter of the shunt way according to the length and the quality of plastic parts molding cycle, the diameter of the commonly used for 16 - to 30 mm, when molding cycle is long, great value.
