[0018] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0019] Refer to Figures 1 - 3 As shown in the figure, a CNC machining precision mold with quick installation and positioning includes a bottom plate 1. A fixed base 2 is arranged at the upper end of the bottom plate 1. Slide grooves 201 are respectively formed through the left and right ends of the fixed base 2. A clamping mechanism 3 and a mold 4 are arranged inside the fixed base 2. The mold 4 is arranged in the middle of the clamping mechanism 3. The clamping mechanism 3 is composed of a first clamping assembly 31, a positioning plate 32 and a second clamping assembly 33. A pair of first clamping assemblies 31 are provided, and the two first clamping assemblies 31 are symmetrically arranged on the inner side of the bottom of the fixed base 2. The positioning plate 32 is fixedly connected to the front side of the bottom plate of the mold 4. The second clamping assembly 33 is arranged at the rear side of the fixed base 2. The mold 4 is composed of an upper mold 41 and a lower mold 42. In this device, the clamping mechanism 3 can quickly position and clamp the mold 4 through the cooperation of the first clamping assembly 31 and the second clamping assembly 33, avoiding the movement of the mold 4 during processing, thereby causing processing errors.

[0020] Specifically, in this embodiment, the first clamping assembly 31 includes a rotating motor 311 and a moving toothed plate 315. The rotating motor 311 is fixedly installed on the bottom plate of the clamping mechanism 3. The moving toothed plate 315 is slidably installed inside the chute 201. The output end of the rotating motor 311 is fixedly connected to a gear 312. The upper end of the gear 312 is meshed with the moving toothed plate 315. The inner end of the moving toothed plate 315 is fixedly connected to a first clamping plate 316. The other end of the first clamping plate 316 is fixedly connected to a first anti-slip pad 317. The outer end of the moving toothed plate 315 is fixedly connected to a limit baffle 318.

[0021] Specifically, in this embodiment, a transmission roller 313 is fixedly connected to the front end of the gear 312. The other end of the transmission roller 313 is rotatably connected to a support seat 314. The support seat 314 is fixedly installed on the upper side of the bottom plate of the fixed base 2. In this device, the mold 4 is placed inside the fixed base 2, so that the front end of the mold 4 is in contact with the positioning block 32. Subsequently, the rotating motors 311 on both sides and the telescopic cylinder 332 at the rear are started. The rotating motor 311 drives the gear 312 to rotate. The gear 312 is meshed with the moving toothed plate 315, thereby driving the moving toothed plate 315 to move, so that the two first clamping plates 316 approach or move away from the mold 4, so as to be able to position and clamp the mold 4.

[0022] Specifically, in this embodiment, the second clamping assembly 33 includes a mounting plate 331. The mounting plate 331 is fixedly installed at the upper rear side of the bottom plate 1. A telescopic cylinder 332 is fixedly installed at the rear end of the mounting plate 331. The output end of the telescopic cylinder 332 penetrates through the mounting plate 331 and is fixedly connected to a second clamping plate 333. The front end of the second clamping plate 333 is fixedly connected to a second anti-slip pad 334. The telescopic cylinder 332 drives the second clamping plate 333 to move towards the mold 4, and cooperates with the positioning block 32 to position and clamp the mold 4. Through the cooperation of the first clamping assembly 31 and the second clamping assembly 33, it is avoided that the mold 4 moves during processing, which may lead to processing errors. At the same time, both the first clamping plate 316 and the second clamping plate 333 are provided with anti-slip pads. The anti-slip rubber pads can increase the friction between the mold 4 and the clamping plate, further improving the clamping effect. On the other hand, it can be avoided that the clamping plate exerts too much pressure on the mold 4, causing damage to the mold 4, and ensuring the processing efficiency.

[0023] Specifically, in this embodiment, positioning blocks 411 are fixedly connected to both the front and rear ends of the upper mold 41. First card slots 412 are opened on both the left and right ends of the upper mold 41. Positioning sleeves 421 are fixedly connected to both the front and rear ends of the lower mold 42. Second card slots 422 are opened on the upper sides of both the left and right ends of the lower mold 42. Mounting grooves 423 are opened on the lower sides of both the left and right ends of the lower mold 42.

[0024] Specifically, in this embodiment, the interior of the positioning sleeve 421 is slidably connected to the lower end of the positioning block 411. An elastic telescopic rod 424 is installed inside the installation groove 423. The outer end of the elastic telescopic rod 424 is fixedly connected to the lower end of the fixing plate 425. A pair of clamping blocks 426 are fixedly connected to the inner side of the upper end of the fixing plate 425. The other ends of the two clamping blocks 426 are respectively arranged inside the first clamping groove 412 and the second clamping groove 422. When the upper die 41 and the lower die 42 are closed, the fixing plates 425 on both sides of the lower die 42 are pulled, and the positioning block 411 in the upper die 41 is inserted into the positioning sleeve 421 of the lower die 42 to complete the positioning connection between the upper die 41 and the lower die 42. Subsequently, the fixing plates 425 are released. Under the action of the elastic telescopic rod 424, the two clamping blocks 426 are clamped in the first clamping groove 412 and the second clamping groove 422 to complete pre-fixing. Subsequently, under the action of the two first clamping components 31, the two first clamping plates 316 respectively abut against the two fixing plates 425, thereby completing the fixation of the die 4.

[0025] The working principle of the present utility model is as follows: In this device, the die 4 is placed inside the fixed base 2, such that the front end of the die 4 is in contact with the positioning block 32, and the upper die 41 and the lower die 42 are closed. First, the fixing plates 425 on both sides of the lower die 42 are pulled, and the positioning block 411 in the upper die 41 is inserted into the positioning sleeve 421 of the lower die 42 to complete the positioning connection between the upper die 41 and the lower die 42. Subsequently, the fixing plates 425 are released. Under the action of the elastic telescopic rod 424, the two clamping blocks 426 are clamped in the first clamping groove 412 and the second clamping groove 422 to complete pre-fixing;

[0026] Subsequently, the rotation motors 311 on both sides and the telescopic cylinder 332 at the rear are started. The rotation motor 311 drives the gear 312 to rotate. The gear 312 is meshed with the moving toothed plate 315, thereby driving the moving toothed plate 315 to move, so that the two first clamping plates 316 approach or move away from the die 4, thereby being able to position and clamp the die 4. At the same time, the two first clamping plates 316 respectively abut against the two fixing plates 425, thereby completing the fixation of the die 4;

[0027] The telescopic cylinder 332 drives the second clamping plate 333 to move towards the die 4, and cooperates with the positioning block 32 to position and clamp the die 4. Through the cooperation of the first clamping component 31 and the second clamping component 33, it is avoided that the die 4 moves during processing, which may lead to processing errors. At the same time, anti-slip pads are provided on both the first clamping plate 316 and the second clamping plate 333. The anti-slip rubber pads can increase the friction force between the die 4 and the clamping plates, further improving the clamping effect. On the other hand, it can be avoided that the clamping force of the clamping plates on the die 4 is too large, causing damage to the die 4, ensuring the processing efficiency.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model.
