Description

Technical Field

[0001] The invention belongs to the technical field of plate production, and in particular relates to high-pressure vacuum extrusion molding plate production equipment. Background Art

[0002] High-pressure vacuum extrusion molded board, referred to as ECP board, is made of silicate cement, fiber (pulp fiber, polypropylene fiber, etc.), siliceous material (quartz powder, etc.) as the main raw materials. It is formed by vacuum high-pressure extrusion, and then cured by low-temperature steam and then high-temperature and high-pressure to form a hollow strip board.

[0004] ECP board has many advantages, including: (1) High strength: ECP board has high strength after high temperature and high pressure curing. Its flexural strength reaches 17MPa, solid compressive strength can reach 60MPa, and hollow compressive strength is greater than 10MPa. (2) Light weight: ECP board is relatively light in weight. For example, the surface density of 60mm thick board is 70~75kg / m², which can reduce the load requirements on the structure and foundation and facilitate construction. (3) High weather resistance: The board structure is dense, the performance is stable, the surface water absorption rate is low, and the freeze-thaw cycle can reach 100 times. Therefore, ECP board has excellent durability and weather resistance. (4) Excellent fire resistance: ECP board is A1 grade non-combustible material. The fire resistance limit of 60mm thick board is 1 hour, which meets the fire resistance performance requirements of buildings. (5) Good sound insulation performance: ECP boards have excellent sound insulation performance. For example, the sound insulation performance of 60mm thick boards can reach 32dB, and the sound insulation performance of 80mm thick boards can reach 36dB. Therefore, ECP boards are widely used in the construction industry.

[0005] However, when the ECP board is subjected to vacuum high-pressure extrusion molding, it is inconvenient to apply high pressure and evacuate the interior of the molding cavity formed between the upper and lower molds, which easily generates holes and bubbles in the molded ECP board.

[0023] The clamping fixing unit 206 includes a fixing sleeve 2062 installed at an equal angle on the top of the movable stopper 2058, the fixing sleeve 2062 is sleeved on the outer side of the guide rod 2053, and the inner wall of the fixing sleeve 2062 is in close contact with the outer wall of the guide rod 2053, a side tube 2063 is fixedly installed on the side of the fixing sleeve 2062 close to the axis of the movable stopper 2058, a clamping block 2064 is movably installed inside the side tube 2063, a pull rod 2066 is fixedly installed on the end of the clamping block 2064 away from the fixing sleeve 2062, one end of the pull rod 2066 passes through the outer side of the side tube 2063, a mounting plate 2067 is coaxially arranged above the movable stopper 2058, a magnetic block 20510 is fixedly installed on the mounting plate 2067, a connecting rod 2068 is hingedly installed at an equal angle on the bottom end of the mounting plate 2067, the other end of each connecting rod 2068 is hinged to the end of each pulling rod 2066, the clamping block 206 The end away from the pull rod 2066 is inserted into the inside of the card slot 2061.

When the moving stopper 2058 moves back, the card block 2064 is inserted into the card slot 2061 again to fix the moving stopper 2058. When the piston 2033 is pushed to generate pressure on the raw material, the reaction force generated by the raw material on the stopper 2059 will not push the moving stopper 2058 to move, thereby improving the forming stability of the plate.

[0025] Working principle: When working, firstly, the bottom wall of the movable mold 201 is pressed against the top wall of the fixed platform 1 by the cylinder 5, and the electromagnet 20511 is controlled to be energized to generate attraction to the magnetic block 20510. Firstly, the mounting plate 2067 moves upward under the action of attraction, thereby pulling each block 2064 into the inside of the side tube 2063 through each connecting rod 2068, so that the block 2064 is disengaged from the card slot 2061, and then under the action of attraction, the mounting plate 2067 continues to move upward, pulling the movable stopper 2058 upward, so that the stopper 2059 moves out of the bottom hole 2052, and finally the movable stopper 2058 moves upward to the connecting hole 2052. Above the hole 2055, the vacuum pump is turned on to drive the air inside the molding cavity 202 to be discharged from the bottom hole 2052, the connecting hole 2055 and the exhaust pipe 204, so that a vacuum is formed inside the molding cavity 202 to prevent the air retained inside from generating bubbles and cavities when the plate is formed. After the vacuum is formed, the electromagnet 20511 is controlled to generate a repulsive force on the magnetic block 20510, so that the movable stopper 2058 moves back downward, so that the stopper 2059 at the bottom end of the movable stopper 2058 is reinserted into the bottom hole 2052, and at the same time, the clamping block 2064 moves back under the elastic force of the compression spring 2065 and is clamped into the clamping groove 2061, so that the movable stopper 2058 is clamped and fixed; Then, the driving motor 2039 is turned on to rotate the screw 2038, thereby driving the sliding block 2035 to move upward along the sliding groove 2037, thereby pulling the pushing piston 2033 to move upward to the top of the feeding pipe 2032, and then the screw feeder is turned on to feed the cement raw material into the molding cavity 202 through the feeding pipe 2032. After the required amount of raw material is fed, the screw feeder is turned off, and then the driving motor 2039 is controlled to pass a reverse current, so that the sliding block 2035 moves downward, thereby driving the pushing piston 2033 to move downward, and the excess raw material in the fixed cylinder 2031 is completely pushed into the molding cavity 202, which is convenient for the plate molding, and at the same time, a high pressure is generated on the raw material in the molding cavity 202 to increase the molding speed; After molding, the movable mold 201 is pulled upward by the cylinder 5. At this time, the molded plate is inside the molding cavity 202. The piston 2033 is driven downward by the driving motor 2039 to push the molded plate inside the molding cavity 202 out to facilitate unloading.
