[0025] It should be noted that the operating height of the roller 121 is slightly higher than the operating height of the second slide 153, so that the roller 121 is the main structure supporting the mold. The outer layer of the roller 121 is made of nylon material with low friction, which can allow the top-supported mold to produce a certain degree of deviation during the limiting process without wearing the roller 121 and the bottom metal of the mold; the reducer 124 cooperates with the drive motor 125 to provide a large torque to drive the various components to operate; the external transfer equipment needs to transfer the mold to a position on the inner side of the middle of the base 10 so that the two driven gears 122 can bear force on the mold. During the limiting process, each L-shaped baffle 171 will not contact the mold that has not been bent into the middle of the base 10 under the control of the PLC component;
[0026] Furthermore, the molds are placed on one side of the middle of the base 10 in sequence through an external transfer device. At this time, each L-shaped baffle 171 is at the corner position of the base 10, and the middle of the base 10 is not blocked.
[0027] Furthermore, the driving motor 125 is started, and the high torque rotational force is outputted through the reducer 124, driving the two gears 122 at the same end of different hollow support plates 11 to rotate, and then the two toothed belts 123 drive all the gears 122 to rotate, so that the multiple rollers 121 rotate synchronously together;
[0028] Furthermore, the rolling rollers 121 drive one side of the bottom of the mold to move toward the middle of the base 10 , and allow the mold to completely enter the middle of the base 10 .
[0029] Please refer to the attached Figure 2 、 4As shown, the first support component 13 includes two first sliding rails 131 arranged on both sides of the top of the base 10, two first baffles 132 arranged at both ends of the top of the base 10, and two first sliding plates 133 slidingly arranged in the middle of the two first sliding rails 131; the transverse translation component 14 includes two first threaded sleeves 141 arranged through the middle of the two first sliding plates 133, a first threaded rod 142 with a nut connected to the middle of the two first threaded sleeves 141 and both ends rotatably connected to the middle of the two first baffles 132, and a first motor 143 arranged at one end of the first threaded rod 142; the second support component 15 includes two second sliding rails 151 arranged at both ends of the top of the first sliding plate 133, two second baffles 152 arranged on both sides of the top of the first sliding plate 133, and two second sliding plates 153 slidingly arranged in the middle of the two second sliding rails 151; the longitudinal translation component 16 includes two second threaded sleeves 161 arranged through the middle of the two second sliding plates 153, a second threaded rod 162 with a nut connected to the middle of the two second threaded sleeves 161 and both ends rotatably connected to the middle of the two second baffles 152, and a second motor 163 arranged at one end of the second threaded rod 162; the clamping component 17 includes four L-shaped baffles 171 arranged in a ring shape on the top of all four second sliding plates 153, a short sponge sleeve 172 and a long sponge sleeve 173 arranged on the inner sides of the two walls of the L-shaped baffles 171.
[0030] It should be noted that each rotating connection has a shaft as a support, the first threaded rod 142 and the second threaded rod 162 are both double-thread structures, cooperating with each first threaded sleeve 141 and each second threaded sleeve 161, so that when rotating, the two first sliding plates 133 and the two second sliding plates 153 can be displaced synchronously in opposite directions, driving each L-shaped baffle 171 to adjust the length and width of clamping, the middle of the first threaded rod 142 is a smooth round rod, the middle bottom of the two hollow supporting plates 11 has a cylinder through which the round rod passes, and the diameter of the cylinder does not affect the operation of the rolling component 12; the short sponge sleeve 172 and the long sponge sleeve 173 are provided with pressure sensors inside, and the pressure sensors transmit electrical signals to the PLC to promote the operation mode of the first motor 143 and the second motor 163;
[0031] Further, according to the length of the mold, the first motor 143 is started, so that the first threaded rod 142 rotates in the middle of the two first baffles 132, the rotating first threaded rod 142 engages through double threads, drives the two first sliding plates 133 to approach or move away from each other through the two first threaded sleeves 141, and drives the L-shaped baffles 171 to approach both ends of the mold;
[0032] Further, when the pressure sensor inside the long sponge sleeve 173 reaches a certain pressure, an electrical signal is sent out, the first motor 143 stops, and the length adjustment is completed;
[0033] Furthermore, according to the width of the mold to be clamped, the second motor 163 is started, causing the second threaded rod 162 to rotate in the middle of the two second baffles 152. The rotating second threaded rod 162 is engaged by double threads, and drives the two second slides 153 to move closer to or away from each other through the two second threaded sleeves 161, so as to achieve a width suitable for mounting the mold.
[0034] Furthermore, when the pressure sensor inside the short sponge sleeve 172 reaches a certain pressure, an electrical signal is sent, the second motor 163 stops, the width adjustment is completed, the mold is limited, and processing can be carried out;
[0035] Furthermore, after the mold processing is completed, the first motor 143 and the second motor 163 rotate in the opposite direction, and cooperate with other components to move each L-shaped baffle 171 back to the corner position of the base 10 to make way for the mold movement channel;
[0036] Furthermore, the driving motor 125 is started again, and cooperates with other components to move the mold out from the other side of the base 10 .
[0037] The working principle of this utility model is:
[0038] First, the mold is placed on one side of the middle of the base 10 in sequence through an external transfer device. At this time, each L-shaped baffle 171 is at the corner position of the base 10, and the middle of the base 10 is unobstructed. The drive motor 125 is started, and the speed reducer 124 outputs a large torque rotational force to drive the two gears 122 at the same end of different hollow support plates 11 to rotate, and then the two toothed belts 123 drive all the gears 122 to rotate, so that multiple rollers 121 rotate synchronously together, and the rolling rollers 121 drive the bottom side of the mold to move toward the middle of the base 10, and make the mold completely enter the middle of the base 10. According to the length of the mold, the first motor 143 is started, so that the first threaded rod 142 rotates in the middle of the two first baffles 132. The rotating first threaded rod 142 is engaged through double threads, and drives the two first slides 133 to approach or move away from each other through the two first threaded sleeves 141, driving the L-shaped baffle 171 to approach the two ends of the mold. 3 reaches a certain pressure, it sends an electrical signal, the first motor 143 stops, the length adjustment is completed, and the second motor 163 is started according to the width of the mold to be clamped, so that the second threaded rod 162 rotates in the middle of the two second baffles 152. The rotating second threaded rod 162 is engaged through double threads, and drives the two second slides 153 to approach or move away from each other through the two second threaded sleeves 161 to achieve a width suitable for installing the mold. When the pressure sensor inside the short sponge sleeve 172 reaches a certain pressure, it sends an electrical signal, the second motor 163 stops, the width adjustment is completed, the mold is limited, and can be processed. When the mold processing is completed, the first motor 143 and the second motor 163 rotate in opposite directions, and cooperate with other components to move each L-shaped baffle 171 back to the corner position of the base 10 to make way for the mold movement channel. The drive motor 125 is started again, and cooperates with other components to move the mold out from the other side of the base 10.
