The invention further comprises a sheath 10, wherein the sheath 10 is wrapped on the top of the U-shaped operating rod 9.
The rectangular die mounting platform frame 1 plays a role in supporting a plastic die; the upper die A supporting legs 51 and 52 are respectively fixed on the long side of the rectangular die mounting platform frame 1 and play a role in supporting the mounting platform frame when the workpiece is to be removed and loaded; the bottom of the U-shaped operating rod 9 surrounds 2 symmetrical rod shafts 8 symmetrically arranged on two sides of the short side of the rectangular die mounting platform frame 1 to realize rotation, and the die removing component (hereinafter referred to as a die removing component) plays a role in moving a frame body and operating device for die removing when being loaded and de-molded; the lever shaft 8 is symmetrically and vertically fixed on the outer sides of the die fixing sliding grooves 21 and 22, and the U-shaped operating lever 9 rotates through the lever shaft 8; the sheath 10 wrapped at the top of the U-shaped operating rod 9 plays roles of skid resistance and protection of hands of an operator; the dowel bars 7 are symmetrically and vertically arranged outside the supporting legs 51 and 52 of the upper die A respectively, and when the device is demolded, vibration force generated by knocking of the U-shaped operating rod 9 and the 2 dowel bars 7 is transmitted into the device from the dowel bars 7 so as to separate a die to be demolded from a concrete member; the demolding supporting legs 31, 32, 33 and 34 are respectively fixed below four corners of the rectangular mold mounting platform frame 1 and play a role in supporting the mold mounting platform frame; the fixing rods 6 are respectively and vertically arranged at the outer sides of the demolding supporting legs 33 and 34, and play a role in fixing the operating rod 9 when the workpiece to be removed is loaded; the stiffening steel bars are respectively connected with the support legs 51 and 52 of the form removal A, the support legs 33 and 34 of the form removal B and the lower part of the die mounting platform frame 1 in an inclined mode, so that the effect of increasing the rigidity of the frame body is achieved.
Preferably, the fixing of the highway ditch cover plate plastic mold demolding device can be realized by welding.
The working principle of the plastic mold demolding device for the highway ditch cover plate of the invention is as follows: the turnover and demoulding of the module to be demoulded are realized by utilizing the lever principle.
According to the improvement of the plastic mold demolding device for the highway ditch cover plate, the U-shaped operating rod 9 is dragged to enable the edges of the mold to be removed to be loaded along the short side direction of the rectangular mold mounting platform frame 1 along the mold fixing sliding grooves 21 and 22.
The supporting legs 51 and 52 of the upper die A are used as supporting points, and the device and the piece to be removed rotate anticlockwise by 90 degrees by pushing the U-shaped operating rod 9. And then the support legs 31 and 32 of the demolding A are taken as fulcrums, and the rectangular mold mounting platform frame 1 is pushed to realize anticlockwise 90-degree rotation of the piece to be taken off.
When the device is used, the impact force generated by the impact between the device and the ground loosens the concrete member and the plastic mould through 2 times of rotation of the piece to be removed, and then the vibration force generated by the impact between the device and the ground loosens the dowel bar 8 through the swinging of the U-shaped operating rod 9, and the dowel bar 8 is transmitted to the device, so that the piece to be removed is vibrated to remove the concrete member from the plastic mould.
When the demoulding device is used for demoulding the plastic mould of the highway ditch cover plate, an operator makes the U-shaped operating rod 9 abut against the fixed rods 6 at two sides of the device, and the supporting legs 51 and 52 of the mould A serve as supporting points to carry the device to the position to be removed. Dragging the U-shaped operating rod 9 makes the edges of the die to be removed load along the short side direction of the rectangular die mounting platform frame 1 along the die fixing sliding grooves 21 and 22.
The supporting legs 51 and 52 of the upper die A are used as supporting points, and the device and the piece to be removed rotate anticlockwise by 90 degrees by pushing the U-shaped operating rod 9. And then the support legs 31 and 32 of the demolding A are taken as fulcrums, and the rectangular mold mounting platform frame 1 is pushed to realize anticlockwise 90-degree rotation of the piece to be removed.
The U-shaped operating rod 9 is swung to strike the dowel bar 8, the generated vibration force is transmitted to the device along the dowel bar 8, and the concrete member is separated from the plastic die due to vibration. And repeating the steps to remove the next component, so that the component is circularly recycled.
