There are two types of electric demoulders: hydraulic and gear transmission. They can be used for demoulding various test specimens with diameters of 50mm, 100mm, 101.6mm, 150mm, 152mm, and heights up to 230mm. (At the same time, our company produces manual demoulders) Main technical parameters: 1. Upward speed of demoulder screw: 70mm/min. 2. Downward speed of demoulder screw: 70mm/min. 3. Maximum movement distance of demoulder screw: 240mm. 4. Maximum maximum upward limit distance of demoulder screw: (L) 270mm. 5. Maximum downward distance of demoulder screw: (L) 30mm. 6. Maximum demoulding force of demoulder screw: 150KN. This is a specialized equipment for manually removing specimens from the mold of lime soil, asphalt, clay and other compaction tests. The manual hydraulic demoulder is mainly used for testing the gradation and asphalt content of asphalt mixtures in road traffic engineering departments and related colleges and universities' scientific research and teaching departments. Suitable for construction supervision of road engineering and on-site rapid testing of asphalt mixture manufacturers. This instrument complies with the JTJ052-2000 standard of the Ministry of Transport. Main technical parameters of manual hydraulic demoulder: 1. Bulk density of material bowl: 1.5 kg 3 kg 2. Power: 1.1 kW 3. Voltage: 220 V 4, speed: 1300~3000 r/min. Electric hydraulic demoulder 1. Main purpose and scope of application: Stepless speed regulation (0-100mm) 4. Maximum working pressure of oil: 40MPa 5. Piston diameter: φ 100mm 6. Maximum piston stroke: 260mm 7. Motor specification: 750WAC380V1400 8 revolutions per minute, net weight: about 210 kilograms. 3. Features of this machine: Electric hydraulic demoulder. 1. This machine is driven by hydraulic pressure, which runs smoothly, safely, and reliably. It has a wide range of ascending speed control and fast descending speed. Compared with mechanical demoulders, it has the advantages of high power, high efficiency, low noise, and long service life, especially meeting the demoulding requirements of high-strength specimens such as cement mixtures. 4、 The main structure and working principle of this machine are composed of the main frame, hydraulic system, pressure gauge, and electrical system. 1. The frame part is mainly composed of crossbeams, columns, trays, oil cylinders, bases, etc. The crossbeam can be equipped with demoulding accessories for demoulding of trial molds with diameters of 101.6mm, 100mm, and 50mm. The center of the oil cylinder plunger can be equipped with long and short rods of 45mm. The drag plate is used for positioning and supporting the mold barrel during demoulding. 2. The hydraulic system consists of a hydraulic pump, oil supply valve, return valve, oil tank, oil filter, oil pipe, and joint. The hydraulic pump is an axial piston high-pressure pump with a flow rate of 0.125Mm/min and a rated pressure of 40MPa. It is directly driven by a 0.75KW three-phase motor and fixed on the base. The oil return valve and the oil delivery valve are installed on the left and right sides of the front panel respectively, both operated by handwheels. The right oil delivery valve can adjust the piston's upward speed, and the left oil return valve is used for the oil cylinder to descend and return oil. The oil delivery valve is equipped with a safety valve, which can overflow in case of overload to provide safety. 3. The pressure gauge of this machine has a precision of 1.5 levels and is shock resistant. It is used to measure the working pressure inside the cylinder. When using it, it should be noted that the pressure value must not exceed 40MPa to prevent damage to the parts. 4. The electrical system consists of an electric motor, start button, stop button, fuse, relay, etc. 5. Usage method: Electric hydraulic demoulder. 1. Before use, first add 6L to the oil tank Hydraulic shaft, check whether the oil pipe joints and fasteners are loose. If they are loose, tighten them to prevent oil leakage and affect use. Check the grounding of the electrical system and whether the fuse is effective. 2. When starting the operation procedure and demolding method, turn the left return valve to the open position and the right oil supply valve to the slow position. Then press the start button on the panel, turn on the power, and the oil pump starts working. Rotate the return valve clockwise, and slowly open the oil supply valve to lift the piston up a certain distance. Observe whether there is any jamming phenomenon. If there is, stop the machine for inspection and elimination. If there is no abnormal reaction, the piston will rise to the limit of oil return to exhaust the air in the system. Observe that there are no bubbles in the left oil cylinder return pipe to start working normally. The sentence is:. When demolding, attention should be paid to the accuracy of the positioning of the mold cylinder, which is the key to the safe operation of the instrument and smooth demolding. Due to the different sizes and structures of various compaction instruments, this machine adopts three different positioning methods for mold testing, and is equipped with corresponding accessories, making it easy and reliable to use. (1) There is a pad iron inside the compression test mold cylinder, and the positioning is achieved by using the Φ 45mm hole on the pad iron. (2) A light heavy blow is applied to the actual test mold of Φ 152X170mm, and the positioning is achieved by using the Φ 180mm waterproof line on the tray, The Φ 100X170mm trial mold and Maser compaction trial mold can be directly removed using the attached Φ 96mm shim with the demoulder, and the Φ 152X170mm trial mold can also be removed using the Φ 96mm shim (3). The machine's accessory is a Φ 45mm, and the long rod is a Φ 50X130mm. When demoulding the special accessory for the trial mold, the height of the tray should be adjusted first to meet different trial molds. Place the trial mold with the test block on the tray, pay attention to accurate positioning, unscrew the oil supply valve to make the piston rise quickly. When approaching the test block, slowly rise to prevent the test piece from falling out and breaking. When the test piece is removed, the power or oil supply valve should be turned off in a timely manner to stop the piston from rising and reverse. Rotate the return valve clockwise to allow the oil in the cylinder to flow back to the tank while the piston descends to its lowest point by its own weight. When it reaches a certain height, close the return valve to control the descent height
