Description of the Invention: [Technical Field of the Invention] The present invention relates to a mold clamping device for opening and closing a mold of an injection molding machine. [Prior Art 1 The clamping device of the existing injection molding machine is mostly a hydraulic clamping mechanism, and the hydraulic cylinder is used to push the mechanical mechanism to complete the opening and closing of the mold. There is also an electric clamping device as shown in the first figure, the connecting rod of the substrate and the clamping mechanism is connected with the nut 2 disposed on the rear template 1', the screw 3, the nut 2, the screw 3, the front end connection The rear end of the mold clamping mechanism 4, the screw 3, is driven by the motor 6' through the pulley mechanism 5. During the rotation of the screw 3', due to the pushing of the nut 2, the advancement or retreat is caused to drive the mold clamping mechanism 4 to operate. The disadvantage of this electric clamping device is that the structure of the transmission part of the screw cup 3 is relatively complicated 'requires the transmission of torque to the screw 3 in motion', which requires opening a keyway (not shown), resulting in miscellaneous The consumption is very large. Secondly, the 'pulley mechanism 5' transmission method is inevitably slippery'. It is not conducive to the precise control of the clamping process. When the servo motor 6 is needed, this shortcoming becomes quite obvious when the clamping process is precisely controlled; The value says that the ice drag &, the transmission mechanism is large and complex, not compact enough, and the multi-stage transmission causes the energy efficiency to decrease. *The structure of the other electric clamping device is as shown in the second figure: the rear template ι, and the connecting link of the == mechanism 4 are connected to the 'moulding mechanism' 4, the nut is installed, and the broadcast is set to 5, by (4) The upper screw 3 is matched with the nut 2, and the screw 3 is driven by the belt motor machine. When the screw 3 rotates, the nut 2 advances and retreats on the screw 3, and drives the mold clamping mechanism 4 to open or close the mold. The disadvantage is that the screw 3, fixed and affecting 200924951 to (four) rod 3, the length of the scale tree, (four) the mechanical mechanism at the time. ——The shortcomings of poor accuracy and short life are also stored. [Invention] The lack of =1: There are: tr. complex, low energy efficiency, poor accuracy of the device.,, is conducive to sophisticated and energy efficient electric The electric clamping device of the mechanical machine comprises a clamping mechanism, the clamping machine, the mechanism comprising the frame, the rear, the movement of the die and the moving template of the fixed mold and the rear template are opposite Closing and separating, the front part of the screw is connected to the mechanical mechanism, wherein: the screw_moving_ is an outer rotor permanent magnet type servo motor, and the rotor connecting nut of the outer rotor permanent magnet type 値 motor, The nut is engaged with the screw. ❹ Further, the rotor of the outer rotor permanent magnet feeding motor is placed on the rear plate through the shaft, and the town passes through the test, and the outer turn + permanent magnet shirt motor Further, the rotor is coaxially arranged with the nut and the screw, and the stator of the outer rotor permanent magnet type motor is connected to the outer casing, and the outer casing is connected to the rear template. Or the outer rotor permanent magnet type motor is arranged on the machine through the bracket. Rack or rear template on the 'screw from the When the outer rotor permanent magnet motor is energized and rotated, the nut rotates and the drive screw advances or retreats. The screw pulls the mold mechanism to complete the mold opening or closing. 200924951 The screw drive of the present invention The compact mechanism and the nut between the cylinders are directly connected with the rotating shell motor, which avoids the energy loss caused by the transmission stage and the efficiency ratio of the screw, and also facilitates the precise control of the screw process. The advantage of the invention is that the structure is tight , Miscellaneous μ v, simple, this efficiency is high, the mold clamping stroke is controlled by the bee. [Embodiment] Example 1 refers to the third figure. The difficulty of the invention includes Qian Shunqi, the job of the mechanical mechanical package The former Wei 1Q, the money _ 17 and the front template 16 of the fixed mold 18, the moving template 15 and the front template 16 can be relatively closed and separated. The screw 8 passes through the rear mold (four), the screw 8 The front part is connected to the cross body wall 14 of the clamping mechanism. The rear plate 1G has an outer rotor permanent magnet servo motor as the driving mechanism of the screw ©, and the rotor 3 connection of the outer rotor permanent magnet ship motor With the stated The screw 8 is matched with the nut 9. The screw 8 is a ball screw, and the nut 9 is a ball nut. The rotor 3 of the outer rotor permanent magnet servo motor is not placed on the rear plate 10 through the tapered roller bearing 2 The rotor 3 of the servo motor is arranged coaxially with the nut 9 and the screw 8, and the stator 6 of the outer rotor permanent magnet type Wei motor is connected to the outer casing 7'. The outer casing 7 is connected to the rear plate 1〇. The rotor 3 is provided with a magnet 4 The stator 6 of the Shishi steel sheet material is wound with a coil 5. The bearing housing 1 for mounting the tapered roller bearing 2 is fixed on the rear template 1 。. 200924951 The rear template 10, the moving template 15 and the front template 16 are all placed over The clamping mechanism comprises: a toggle connecting rod mechanism, the rear template 10 is symmetrically connected - the rear end of the elbow hand u, the front end of the cashmer u is simultaneously with the connecting rod 12 and the curved The rear end of the large connecting rod 13 is hinged, and the other ends of the two curved small connecting rods 12 are symmetrically hinged at both ends of the cross-car wall 14, and the front ends of the two curved large connecting rods 13 are symmetrically hinged at the upper and lower ends of the moving template 15. 〇❹ The rotor 3 is fixed with the ball screw nut 9. When the clamping motor is positively energized, the rotor rotates clockwise. The main shaft 9 rotates and the screw 8 rotates. At this time, the screw 8 will rotate. The end is extended. The screw 8 is translated with the crossover wall 14, and at this time, the crossover wall 14 drives the shaft template 15 to move along the tie rod 19 to generate the clamping molds 17, 18; The rotor rotates when the motor is negatively charged. The screw 8 will be retracted from the end of the motor shaft, and the screw drives the cross-car ^ thousand movements. At this time, the cross-car wall drives the template π through the curved-link mechanism to make the movement of the mold 17 and 18 along the tie rod 19 (Fig. The machine is not compact. The machine is compact and simple, and the nut is directly and the outer rotor is always beneficial. Her money _ riding the ship, the ratio of the occupational efficiency is also beneficial to the precise control of the screw process. : The same _ and _ _ is the mechanical mechanism, and the rest with the first embodiment of the clamping mechanism of this embodiment includes: the rear template l〇i, the moving template (5) and the previous 200924951 ::: at the level • On; cross car wall i4i 'rear template oil, _ 汕 的 的 ' ' 其中 其中 其中 其中 其中 其中 其中 其中 其中 其中 其中 其中 其中 其中 接 她 她 她 她 她 她 她 她 她 她 她 她 她 她 她 她 她 她 她 她 41 41 41 41 41 41 41 41 41 41 Move the template (5).
