Description

Technical Field

[0001] The invention relates to a demoulding device, which is mainly used for demoulding a thermal insulation block and belongs to the technical field of thermal insulation block production equipment. Background Art

[0002] With the development of economy and the progress of society, energy conservation has become a consensus, and building energy conservation is an important area of ​​energy conservation. With the continuous improvement of building energy conservation standards, thermal insulation blocks are used more and more widely as building energy conservation materials.

[0003] With the increasing demand for thermal insulation blocks, in order to improve production efficiency, the use of automatic production lines to produce thermal insulation blocks has become the first choice for many manufacturers.

[0004] In the automatic production line of thermal insulation blocks, the blocks initially formed in the mold need to be demolded to separate the blocks from the mold. The demolding of the blocks relies on a demolding machine to separate the blocks from the mold. The Chinese patent application with publication number CN103240799A discloses a demolding device, in which four mold lifting devices for lifting the mold are respectively installed at the four corners of a mobile vehicle. Each mold lifting device is provided with a demolding cylinder, which drives the corresponding lifting foot to rise and fall to lift the mold. The four mold lifting devices act separately. Since the weight of the mold is very large, the separate action of the four mold lifting devices can easily lead to asynchronous lifting action, resulting in radial force on the cylinder, the cylinder is easily skewed, and the cylinder is easily damaged. In addition, since the mold lifting device is installed on the mobile vehicle, the mold lifting device is not easy to be accurately positioned with the mold vehicle, resulting in the inability to accurately position the pressure head and the mold, affecting demolding. Summary of the invention

[0005] In view of the above-mentioned defects existing in the prior art, the present invention provides a demoulding device which can synchronously lift the mold and has accurate movements.

[0006] The present invention is realized by the following technical scheme: a demoulding device, characterized in that it comprises a main frame, a mobile vehicle, a mold lifting device, and a block pressing device, wherein the upper part of the main frame is provided with parallel guide rails on both sides along the length direction thereof, the mobile vehicle is movably provided on the guide rails through wheels provided at the lower part of the frame, the upper part of the frame of the mobile vehicle is provided with four groups of synchronous lifting mechanisms arranged symmetrically in pairs, each group of the synchronous lifting mechanisms comprises a gear and a guide wheel provided opposite to the gear, and two of the two mutually symmetrical groups of synchronous lifting mechanisms are provided with a guide wheel arranged opposite to the gear. The gears are connected through a rotatable intermediate shaft. A guide sleeve A is fixedly arranged at each of the four corners of the frame of the mobile vehicle. The block pressing device includes a pressure head frame arranged at the lower part of the mobile vehicle, a pressure head connected to the lower part of the pressure head frame, and a pressure head lifting cylinder. Four racks are vertically fixedly arranged on the pressure head frame. The four racks are respectively meshed with the gears of the four sets of synchronous lifting mechanisms on the frame of the mobile vehicle. The guide wheels of the four synchronous lifting mechanisms are respectively matched with the corresponding racks. Four guide rods are vertically fixedly arranged on the pressure head frame. The four guide rods are vertically fixedly arranged on the pressure head frame. The rods are respectively inserted into four guide sleeves A arranged on the frame of the mobile vehicle, the cylinder body of the pressure head lifting cylinder is fixedly installed in the middle of the frame of the mobile vehicle, and the piston rod of the pressure head lifting cylinder is connected to the pressure head frame. The mold lifting device includes two demoulding cylinders and two groups of lifting foot mechanisms respectively arranged on opposite sides of the pressure head frame. The two demoulding cylinders are respectively vertically fixedly installed on both sides of the pressure head frame, and a vertically arranged positioning rod is respectively fixedly connected on both sides of the pressure head frame. Each group of the lifting foot mechanisms includes a lifting foot bracket, a lifting foot guide The lifting foot bracket is fixedly mounted on both sides of the pressure head bracket, and two guide shafts are vertically fixedly mounted on the lifting foot bracket.

The two lifting foot cylinders are respectively arranged corresponding to the lifting feet, one end of the lifting foot cylinder is hinged to the lifting foot guide frame, and the other end is hinged to the lifting foot. The piston rods of the two demoulding cylinders are respectively connected to the two lifting foot guide frames.

Then the moving car drives the demoulded mold back to its original position, and the lifting foot cylinder is actuated to cause the lifting foot to release the mold, and the mold is placed on the mold cart to complete the entire demoulding work.

The front end of the positioning rod is designed as a V-shaped edge, which can cooperate with the V-shaped positioning block set on the side of the mold, so that when the mold car drives the mold to approach the demoulding device, the V-shaped edge of the positioning rod cooperates with the inclined surface of the V-shaped block to automatically guide the mold, effectively preventing the problem of the pressure head and the block not being aligned due to inaccurate mold positioning, and thus failing to demould.

[0010] Furthermore, to facilitate adjustment of the position of the positioning rod, the positioning rod is installed on the base plate through a mounting seat, the base plate is fixedly connected to the pressure head frame, a strip mounting hole is provided on the base plate, and the mounting seat is connected to the base plate by bolts cooperating with the strip mounting hole.

[0011] Furthermore, the piston rod of the pressure head lifting cylinder is connected to the pressure head frame through a pin shaft.

[0012] Furthermore, a hydraulic station is arranged on the frame of the mobile vehicle. The hydraulic station is arranged on the mobile vehicle to ensure that no interference occurs when the equipment is working, and to ensure reliable operation of the equipment.

[0013] Furthermore, in order to improve the reliability of the equipment operation, the rack is fixed on a square tube vertically fixed on the pressure head frame, and the upper ends of the square tubes are connected together by connecting square tubes.
