Brief Introduction to Vacuum Compression Machine:
Vacuum vulcanizing machine is a machine for vacuum processing raw materials. The vulcanization process is mainly composed of a main body, a vacuuming device, a hydraulic transmission system and an electric control system. The vacuum device is connected with the lower template to form a sealed space, and the vacuum device is During the opening and closing and vulcanization process, a venting groove is embedded in the open end of the vacuum hood, and a movable beam that can move up and down along the column is provided with two parallel guide rails, and one end of the guide rail extends to the opening and closing device. Inside, the guide rail is provided with a mold formed by the upper and lower templates which can be moved along the guide rail into the main body or in the mold opening and closing device.
Function of Vacuum Compression Molding Machine:
The pre-heating of the rubber vulcanization process, the automatic exhaust gas after feeding, the pressure-proof vulcanization, the chronograph alarm, the automatic mold opening, the product ejection and other functions are integrated. It adopts PLC programmable controller or manual operation (customized according to the actual needs of users), records the required process flow and facilitates operation management. The vulcanizing machine is suitable for vulcanization of various rubber products, and is the advanced hydraulic machine heat for pressing various thermosetting plastics. Pressure equipment. The vulcanizer is divided into three types: electric heating, steam heating and heat transfer oil heating. The hydraulic press has perfect functions and compact structure. It has functions such as timed mode locking, automatic pressure compensation, automatic temperature control, automatic timing and time alarm. The surface temperature of the hot plate is uniform and the temperature control is accurate. The temperature controller can accurately record the temperature data and maintain pressure. Stable and reliable, safe and convenient to operate, the use of this machine can ensure product quality, provide production efficiency, and obtain significant economic benefits.
PLC, touch screen control, can achieve manual and automatic control. The automatic control can realize the functions of clamping, exhausting, temperature control, vulcanization timing, alarm, mold unloading, etc.; the touch screen timely displays the temperature of each heating zone of the hot plate.
The hydraulic cylinder of the press adopts ZG270-500 material, the plunger adopts the hard-hardened alloy cast iron with fine texture, and is refined after casting; the sealing form of the hydraulic cylinder is YX-type sealing ring.
The hot plate top adopts the hydraulic automatic top iron. Under the action of the four oil cylinders, the horns on both sides of the hot plate advance and retreat at the same time; the ends of the hot plate are provided with anti-horn overlapping devices.
Each heating zone of the hot plate is provided with a set of temperature-regulating valve groups. Under the control of the PLC, the temperature of each heating zone of the hot plate is ensured to be uniform.
Hydraulic system: the use of well-known brands of hydraulic stations at home and abroad, under the control of PLC, can achieve automatic: mold clamping, exhaust, mold unloading.Mechanical synchronous balance mechanism: There is a synchronous shaft running through the unit below the platform. Both ends of the shaft are provided with rack and pinion to ensure the horizontal lifting of the platform.
Clamping guide: There are clamping guides on both sides of the lower table. The frame plate and the platform are mounted with guides. The guides are used to machine the bevels. The distance between the bevels can be adjusted by the top wires.Open mold assisting mechanism: The four cylinders under the platform are opened when the mold is opened, and the platform is forcibly pulled down to prevent the stick from opening.
Vacuum forming features:
(1) Saving raw and auxiliary materials, light weight, convenient transportation, good sealing performance, and meeting the requirements of environmentally friendly green packaging;
(2) It can pack any special-shaped products, and no additional buffer material is required for packing;
(3) The packaged product is transparent, beautiful in appearance and easy to sell;
(4) The packaged products are suitable for mechanization and automatic packaging, which is convenient for modern management, saving manpower and improving efficiency.
The 4RT surpasses traditional top opening mold that can be used for taking out the final product when there are triple or four mold plates with the design of opening mold, pushing out the mold in between, and rising thimble to eject the final production.
4RT Machine motions flow:
Unload the mold
M1 goes up to open the mold
M2 goes up and separates from the mold
M3 follow the K goes backward
M2 goes down
L goes up take out the finished product, clean and place new material for re-start.
L goes down; M2 goes up, M3 follow the bottom plate goes forward.
M2&M1 go down.
Mold in, main ram goes up and molding than main ram goes down and mold-out when completed the process
