Gas-assisted injection molding technology features (1) The design of the mold cavity should ensure the flow balance to reduce the uneven penetration of the gas, and ensure the flow balance is also a design principle of the common injection molding mold, but this is more important for the gas-assisted injection molding products. (2) The mold design should consider the influence on the process parameters, because gas-assisted injection molding is much more sensitive to process parameters than ordinary molding. In injection molding, small differences in mold wall temperature or injection volume can lead to asymmetry of gas penetration in symmetrical parts. Gas-assisted injection molding equipment (1) Ordinary injection molding machine (the metering accuracy is slightly higher). (2) Nitrogen control system, including self-sealing gas-assisted nozzles. (3) High pressure nitrogen generator. (4) Industrial nitrogen cylinders and air compressors that provide supercharged power. (5) A mold designed and manufactured for gas-assisted injection. (6) Gas-assisted injection molding gas auxiliary nozzle The nozzle air intake mode uses a special self-closing gas-assisted nozzle. After the plastic injection is finished, the high-pressure gas directly enters the plastic inside by the nozzle, and forms an extended closed space-air cavity according to the air passage and maintains a certain pressure until the pressure is maintained. Cooling, before the mold is opened, the nozzle is forced to separate from the product channel by the backrest of the table, and the gas is discharged from the product. (7) gas needle The air needle intake method is to install an exhaust deviceâ??a gas needle at a specific position of the mold. When the plastic is injected into the cavity, the gas needle is wrapped inside the plastic; at this time, the high-pressure gas is discharged, and the gas needle forms an extended closed space-air cavity according to the air passage inside the plastic, and maintains a certain pressure until cooling, and the mold is opened. Previously, the gas in the air chamber was discharged from the interior of the plastic by the control device by means of a gas needle.

Mixing truck is a special truck used to transport concrete for construction; Because of its appearance, it is also often called the field snail car, olive car. These trucks are equipped with cylindric mixing tanks to carry the mixed concrete. Concrete mixing transport vehicle by the car chassis and concrete mixing transport special device. The concrete mixing transport vehicles produced in our country use more than two kinds of general chassis provided by vehicle manufacturers. Its special mechanism mainly includes the force retractor, stirring cylinder before and after the support, reducer, hydraulic system, mixing cylinder, operating mechanism, cleaning system, etc. The working principle is that the power of the car chassis is taken out by the force device, and the variable pump of the hydraulic system is driven, and the mechanical energy is converted into hydraulic energy to the quantitative motor, and the motor is driven by the reducer, and the mixing device is driven by the reducer to mix the concrete.
Boring machine is a machine for digging tunnels in flat ground. There are many types of boring machine: according to the job object, it is divided into ordinary machine and tunnel Boring machine, referred to as TBM; According to the operation mode, it is divided into open roadheader and shield roadheader. Tunnel boring machine (TBM) is a kind of comprehensive equipment which uses mechanical rock crushing, ballast and support to carry out continuous operation. According to the cutting process of the roadheader on the working surface, it is divided into full-section roadheader and partial section roadheader.
Shield tunneling machine is a tunnel boring machine using shield tunneling method. Shield construction method is tunneling machine in tunneling at the same time to build (laying) tunnel "shield" (refers to the supporting segment), it is different from the open construction method. Internationally, generalized shield tunneling machine can also be used in rock formation, but different from the open (non-shield tunneling machine) tunnel boring machine. But in our country, the tunnel tunneling machine used for soft soil layer is habitually called the narrow sense shield machine, will be used for the rock formation to be called the (narrow sense) TBM. According to the working principle, the shield machine is generally divided into hand digging shield, extrusion shield, semi-mechanical shield (local pressure, global pressure), mechanical shield (open-chest cutting shield, pneumatic shield, mud and water pressure shield, earth pressure balance shield, mixed shield, special-type shield).
Cold mill is a new type of cold steel mill processing equipment. The machine can be hot rolled wire rod diameter between 6.5 mm to 12 mm, hot rolled disc circle processing into the finished product specifications diameter of 5 mm to 12 mm cold rolled ribbed steel bar. The cold-rolled ribbed steel bar rolled by cold rolling mill is the replacement of cold-drawn low carbon steel wire in prestressed concrete members. In cast-in-place concrete structures, the grade I steel bar can be replaced to save steel. It is a better kind of cold-worked steel in the same kind. If speed regulation is not required in the process of cold rolling mill, AC motor can be used; If speed regulation is needed in the process of cold rolling mill, DC motor can be used.
