Die casting machine is mainly composed of mold closing mechanism, injection mechanism, hydraulic system and power control system. In addition, die casting machine also has parts and components and frame, other devices, auxiliary devices and other parts. Working principle of die casting machine: (1) At the beginning of the slow injection movement in the first stage, the hydraulic oil of the system enters the cavity through the oil circuit integrated plate, and then enters the cavity through the channel, so as to push the injection piston to the left to achieve the slow injection. (2) Two-stage rapid injection movement. When the injection punch exceeds the sprue of the barrel, the control valve of the accumulator opens, and the hydraulic oil enters the cavity rapidly through and through the sprue. The volume of the hydraulic oil in the cavity increases rapidly, and the injection speed increases. (3) Three-stage supercharging movement of metal liquid filling into the cavity, immediately terminated, alloy liquid began to solidified, then the punch forward resistance increases, controlled by the computer program, the use of accumulator control valve open, through the rapid entry into the cavity, so as to promote the pressurized piston and piston rod left fast move. When the piston rod and floating piston inside and outside cone joint, truncated, so that the formation of a closed chamber, pressurized piston, piston rod, floating piston and the pressure of the chamber together to obtain a pressurized effect of the piston. (4) slow, fast and pressurized fast and slow time policy can be adjusted by the oil circuit board control oil valve () the role of the hydraulic transmission system: through the hydraulic components (power components, executive components, control components, auxiliary components, working medium) and loop transmission power, so as to achieve a variety of actions.

China's first self-developed die casting robot was successfully trial-produced in Longhua, Bengbu   On May 30, 2022, Bengbu Longhua Die Casting Machine Co., LTD. * Hefei Institute of Material Science, Chinese Academy of Sciences * Bengbu College * Anhui Peitian Robot Group Co., LTD., two science and technology manufacturing r&d enterprises and two big institutes, actively respond to the great call of encouraging "cooperation between institutes, industries, universities and research institutes".  The first "die casting robot" jointly developed and manufactured by many parties in China has been successfully debugged in Longhua die casting Machine production base in Bengbu.   The die-casting robot has completely independent product intellectual property rights, the degree of localization reaches 99%, and the cost performance is the world's first.  In r&d and production, it has successively won 874 patents (including 543 invention patents and 54 PCTpatents) and 74 computer software Copyrights.  The successful research and development of this product has fundamentally changed the world's understanding of die casting robots. After entering the market, it will completely shake the monopoly position of four foreign robot families (Fanuc, Yaskawa, Kuka and ABB) on the global die casting robot market.  The birth of this product can not only reduce the production and procurement costs of domestic and foreign die-casting robot manufacturers (die-casting machine manufacturers and die-casting manufacturers), but also improve the competitiveness of national brands in the international market.   "Domestic AI die casting robot, help science and technology power, let the world fall in love with Made in China!"   

On May 24, 2022, Bengbu, vice President of Chinese people's political consultative conference (CPPCC), the MDC of Anhui provincial party committee standing committee, the MDC Bengbu municipal party committee chairman comrade Zhou Jingfei with MDC Bengbu council organization department minister kingship and department leaders come to Bengbu Longhua die casting machine co., LTD of Bengbu Longhua with Hefei institute of Chinese Academy of Sciences major joint research and development production of die-casting robot to inspect the progress of the project, And provide guidance. Zhou Jingfei pointed out: science and technology power, manufacturing prosperous country, the domestic die casting robot into China's Fanuc. We will try our best to give full play to the regional advantages of bengbu traditional manufacturing industrial base, and make die-casting machine and die-casting machine special robot project bigger and stronger with longhua's experience and wisdom.

A servomechanism, also known as a follow-up system, is a feedback control system designed to accurately follow or reproduce a process. Servo system an automatic control system that enables the position, orientation, state and other output controlled quantities of the object to follow arbitrary changes in the input target (or a given value). Its main task is to magnify, transform and control the power according to the requirements of the control command, so that the torque, speed and position control of the output of the drive device is very flexible and convenient. Servo system in many cases, the amount of points to be controlled (system) of the output is the mechanical displacement or displacement velocity and acceleration feedback control system, its role is to make the output of the mechanical displacement (or Angle) to accurately track the input displacement (or Angle), its structure and other forms of feedback control system there is no difference in principle. Servo system was initially used in the national defense industry, such as gun control, ship, aircraft autopilot, missile launch, etc., and then gradually promoted to many sectors of the national economy, such as automatic die-casting production line, wireless tracking control, etc. First, the main role 1. Control high-power load with low-power instruction signal; 2. In the absence of mechanical connection, the input shaft controls the output shaft located in the distance to achieve remote synchronous transmission; 3, make the output mechanical displacement accurately track electrical signals, such as recording and indicating instruments. Ii. Development history Servo is a shortening of ServoMechanism, which comes from Greece and means slave. As the name suggests, ServoMechanism refers to the system following external instructions to perform the desired motion. The motion factors include position, speed and torque. Reviewing the development history of servo system, from the earliest hydraulic and pneumatic to the current electrification, servo system composed of servo motor, feedback device and controller has gone through nearly 50 years. Nowadays, with the continuous maturity of technology, AC servo motor technology with its excellent cost performance, gradually replace DC motor to become the dominant motor servo system. The mature technology of AC servo system also makes the market show a rapid diversified development, and become one of the supporting technologies of industrial automation. 3. Die-casting machine equipped with servo robot
