[0002] In the plastics industry, finished products are mainly formed by extrusion of various molds. Due to the different models of finished products, different molds need to be used for processing, which requires the molds on the machine to be disassembled and assembled. Although the traditional socket ratchet wrench reduces the user's strength requirements, in order to further improve the efficiency of mold disassembly and assembly and reduce the user's strength requirements, the corresponding electric wrench will be used for mold removal, which will make the use process simpler and faster.

[0003] When using the electric wrench, the spatial layout between some molds is different. Since the handle of the electric wrench is too long or too short, it cannot be used more flexibly in different areas. To address the above problems, we have launched an electric wrench that is convenient for molds to go up and down the machine. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The utility model discloses an electric wrench which is convenient for a mold to be mounted on and off a machine platform and is mainly used in the scene of disassembling and assembling a mold on a machine platform.

[0025] Reference Figure 1 , Figure 3 and Figure 4 , an electric wrench that is convenient for the upper and lower platforms of molds, comprising a sleeve arm 1, a connecting rod 3 is fixedly connected to the lower end of the sleeve arm 1, teeth 4 are evenly provided on the left surface of the connecting rod 3, an adjusting mechanism 2 is connected to the lower end of the connecting rod 3, and the adjusting mechanism 2 is used to adjust the expansion specifications of the connecting rod 3; the adjusting mechanism 2 comprises a handle 201 slidably connected to the lower end of the connecting rod 3, a gear roller shaft 202 is rotatably connected to the upper left end of the handle 201, a slide groove 203 is provided inside the upper left end of the handle 201, a cone head clamping plate 204 is slidably connected inside the slide groove 203, a shift block 205 is fixedly connected to the left side of the cone head clamping plate 204, and springs 206 are connected to the front and rear ends below the shift block 205;

[0026] In this embodiment, when a motor wrench is used to remove the mold on the machine, since the position of the mold fixing bolt is narrow and the fixing bolt is on the back of the mold, the electric wrench needs to be inserted horizontally, and the total length of the electric wrench is long. At this time, by pushing the push block 205 downward, the cone head clamping plate 204 is forced to move downward in the slide groove 203, and the cone head at the upper end of the cone head clamping plate 204 is pulled out from the tooth gap of the gear roller shaft 202. At this time, the restriction on the gear roller shaft 202 is released, and the gear roller shaft 202 can be pushed to rotate, and the gear roller shaft 202 is meshed with the teeth 4 on the connecting rod 3. The connection causes the connecting rod 3 to slide downward inside the handle 201, shortening the distance between the handle 201 and the sleeve force arm 1. After the distance is adjusted, the shift block 205 is released, and the transmission cone head clamp 204 of the shift block 205 is pushed into the tooth gap of the gear roller shaft 202 by the spring 206, thereby limiting the rotation of the gear roller shaft 202. At this time, the electric wrench can be placed horizontally in the narrow area to loosen the bolts on the back of the mold. The total length of the electric wrench can be adjusted to adapt the electric wrench to different environments, thereby improving the practicality of the electric wrench.

[0027] Reference Figure 1 and Figure 2In a preferred embodiment, the upper end of the sleeve arm 1 is connected to the main body shell 5, a quick release button 8 is arranged on the front right side of the main body shell 5, a rotating part 6 is rotatably connected inside the main body shell 5, a sleeve 7 is installed on the front side of the rotating part 6, a forward and reverse switch 9 is arranged on the upper front end of the sleeve arm 1, a handle 10 is connected to the right side of the sleeve arm 1, a battery 11 is installed on the lower left end of the main body shell 5, a charging port 12 is arranged on the lower end of the battery 11, and a motor switch 13 and a safety switch 14 are respectively arranged on the upper right end of the sleeve arm 1;

[0028] In this embodiment, when using an electric wrench to remove a bolt, first remove the sleeve 7 by pressing the quick-release button 8, replace the sleeve 7 with a sleeve of the corresponding size of the bolt, and then hold the handle 10 with one hand to prevent excessive torque when removing the bolt, which may cause harm to personnel and improve safety in use. At that time, press the safety switch 14 first and turn on the power to further improve safety in use and prevent accidental contact with the motor switch 13, which may cause harm to personnel. At this time, press the motor switch 13 to drive the rotating part 6 to drive the sleeve 7 to rotate and loosen the bolt. When the bolt needs to be tightened, the forward and reverse switch 9 can be turned to adjust the rotation direction of the rotating part 6, thereby disassembling and assembling the bolt by electric means, reducing the long-term labor intensity of the staff. After the electric wrench is used, the battery 11 is replenished with power through the charging port 12 for the secondary use of the electric wrench.

[0029] Working principle: When using the motor wrench to remove the mold on the machine, due to the narrow position of the mold fixing bolts, the fixing bolts are on the back of the mold, and the electric wrench needs to be inserted horizontally. The total length of the electric wrench is long. At this time, by pushing the block 205 downward, the cone head clamping plate 204 is pushed downward in the slide groove 203, and the cone head at the upper end of the cone head clamping plate 204 is pulled out from the tooth gap of the gear roller shaft 202. At this time, the restriction on the gear roller shaft 202 is released, and the gear roller shaft 202 can be pushed to rotate, and the gear roller shaft 202 and the upper teeth 4 of the connecting rod 3 are connected. The meshing connection causes the connecting rod 3 to slide downward inside the handle 201, shortening the distance between the handle 201 and the sleeve force arm 1. After the distance is adjusted, the shift block 205 is released, and the transmission cone head clamp 204 of the shift block 205 is pushed into the tooth gap of the gear roller shaft 202 by the spring 206, thereby limiting the rotation of the gear roller shaft 202. At this time, the electric wrench can be placed horizontally in the narrow area to loosen the bolts on the back of the mold. By adjusting the total length of the electric wrench, the electric wrench can be adapted to different environments, thereby improving the practicality of the electric wrench.
