[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to a positioning and clamping device for mold processing, comprising a base 1, a clamping mechanism 2 on the top of the base 1, and a limiting mechanism 3 on the clamping mechanism 2.

[0025] Specifically, by Figure 2-4The clamping mechanism 2 includes a U-shaped plate 201 located above the base 1. A reinforcing block 206 is fixedly connected between the U-shaped plate 201 and the base 1. Two upright plates 204 are symmetrically fixedly connected to the U-shaped plate 201. Both upright plates 204 are fixed to the top of the base 1. Guide rods 207 are fixedly connected between the two upright plates 204 and the U-shaped plate 201. A guide plate 209 is movably sleeved between the two guide rods 207. The guide plate 209 is symmetrically fixedly connected to the U-shaped plate 201. Two springs 205 are connected, and the two springs 205 are respectively sleeved on the outside of the two guide rods 207. The base 1 is provided with a through groove 4, and a slide rod 2012 is fixedly connected in the through groove 4. A slide plate 2010 is movably sleeved on the outside of the slide rod 2012. A clamping plate 203 located above the base 1 is fixedly connected to the side of the slide plate 2010 near the guide plate 209. Rubber blocks 208 are fixedly connected to the sides of the clamping plate 203 and the guide plate 209 that are close to each other. The rubber blocks 208 are used to prevent... Damage to the mold is caused by the following: an inner plate 2015 is fixedly connected to the through groove 4; one end of the slide rod 2012 is fixedly connected to the inner plate 2015; a screw 2013 located below the slide rod 2012 is rotatably connected to the through groove 4; one end of the screw 2013 is fixedly connected to a drive motor 2014, which is fixed to the inner plate 2015; a sliding plate 2010 is threaded onto the outside of the screw 2013; and two support blocks 2016 are symmetrically fixedly connected to the bottom of the clamping plate 203. The bottom of each of the two support blocks 2016 is provided with a support wheel 2011 located at the top of the base 1. When the clamping plate 203 moves horizontally, the two support wheels 2011 roll on the top of the base 1, which supports the clamping plate 203 and ensures the stability of the clamping plate 203 when it moves. A support roller 202 is rotatably connected in the through groove 4. The support roller 202 is located on the side of the inner plate 2015 away from the slide bar 2012. By setting the support roller 202, it is convenient for the mold to move on the support roller 202.

[0026] In use, the mold is first placed on the support roller 202 so that the mold abuts against the rubber block 208 on the guide plate 209. Then, the drive motor 2014 is started, which drives the screw 2013 to rotate and causes the slide plate 2010 to slide along the slide rod 2012. At the same time, the clamping plate 203 moves horizontally closer to the mold. When the rubber block 208 on the clamping plate 203 abuts against the mold, the clamping plate 203 continues to move, pushing the mold so that the guide plate 209 slides along the two guide rods 207. Both springs 205 are compressed, and under the action of the elastic force of the two springs 205, the guide plate 209 applies stable pressure to the mold, and finally quickly achieves the positioning and clamping of the mold.

[0027] Specifically, by Figure 5The limiting mechanism 3 includes two guide blocks 301, which are movably sleeved on the outside of two guide rods 207. A limiting frame 302 is fixedly connected to the outside of each of the two guide blocks 301. A soft pad 303 is fixedly connected to the side of each limiting frame 302 that is close to each other. By setting the soft pad 303, damage to the mold is avoided. Two movable rods 304 are symmetrically rotatably connected to the outside of the guide plate 209. The ends of the two movable rods 304 away from the guide plate 209 are rotatably connected to the two guide blocks 301 respectively.

[0028] In use, when the mold pushes the guide plate 209 to slide along the two guide rods 207, the two movable rods 304 drive the two guide blocks 301 to slide along the two guide rods 207 respectively. At the same time, the two limit frames 302 move closer to each other until the two soft pads 303 are in contact with the mold, thereby achieving front and rear clamping of the mold and finally ensuring the stability of the mold.
