Description

Technical Field

[0001] This utility model relates to the field of mold testing technology, and in particular to a high-precision mold forming accuracy testing device. Background Technology

[0002] A mold is a tool composed of various parts with a specific contour or internal cavity shape. Under the action of external force, it can shape a blank into a part with a specific shape and size. Molds are widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. After the mold is formed, it needs to be inspected. Mold inspection equipment refers to the process of quality inspection and performance testing of the mold to ensure that the quality and performance of the mold meet the standard requirements.

[0003] A Chinese patent publication (CN115122550A) discloses an intelligent detection device for mold forming, comprising a sealing cylinder. The sealing cylinder is cylindrical with an opening at its lower end. An annular rubber gasket is fixedly connected to the lower end face of the sealing cylinder. Two fixing rings are fixedly connected to the inner wall of the sealing cylinder. An elastic sealing layer is disposed between the two fixing rings, and the upper and lower surfaces of the elastic sealing layer are respectively bonded to the two fixing rings. A gap is left between the elastic sealing layer and the inner wall of the sealing cylinder, and the gap is filled with liquid. The device is activated by bonding the liquid between the two fixing rings. An elastic sealing layer is attached, with a gap between the elastic sealing layer and the inner wall of the sealing cylinder, and the gap is filled with liquid. A transparent tube is installed on the outside of the sealing cylinder, and the lower end of the transparent tube is connected to the inner cavity of the sealing cylinder and located between two fixed rings. After the annular rubber pad on the lower surface of the sealing cylinder is attached to the surface of the mold to be tested, the air pressure in the inner cavity at the lower end of the sealing cylinder is increased, causing the elastic sealing layer to undergo elastic deformation. At this time, the liquid level in the transparent tube rises. After standing for a certain period of time, observe whether the liquid level in the transparent tube drops, and you can detect whether the surface of the mold to be tested has protrusions or depressions.

[0004] The aforementioned mold inspection device, during its use, gradually revealed the following defects:

[0005] (1) The above-mentioned testing device is not equipped with a mold clamping and fixing device. When encountering a mold with an irregular appearance, the mold is not stable, which will directly affect the testing operation of the testing device and may also lead to inaccurate test results.

[0006] (2) Most of the clamping blocks on traditional clamping devices are integral or inconvenient to disassemble. After long-term use, the clamping blocks may be worn or damaged. At this time, it is very inconvenient to replace the clamping blocks, which not only wastes a lot of time, but also reduces work efficiency. Utility Model Content

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the quick-release replacement component 5 includes a storage hole 51. Two storage holes 51 are symmetrically opened on the arc-shaped clamping block 42. A pin shaft 52 is provided inside the storage hole 51. A spring 53 is provided inside the storage hole 51.

The pin shaft 52 is inserted into the limiting hole 54. The quick-release replacement component 5 is also provided at both ends of the second clamping plate 44. The pin shaft 52 plays a limiting role in the arc-shaped clamping block 42.

[0041] The first clamping plate 41 has U-shaped plates 55 at both ends, and the U-shaped plates 55 are slidably connected to the push rod 56. The push rod 56 has a pressure plate 57, and a spring 58 is sleeved on the outer surface of the push rod 56. The first clamping plate 41 has guide blocks 59 at both ends, one end of the push rod 56 is located inside the guide block 59, and the spring 58 is located between the guide block 59 and the pressure plate 57. The other end of the push rod 56 has a pull plate 510. The push rod 56 is pushed to move by the pull plate 510. The push rod 56 pushes the pin shaft 52 to disengage from the limiting hole 54 and retract into the storage hole 51. Then the arc-shaped clamping block 42 is removed from the first clamping plate 41 to facilitate the replacement of the clamping block.

[0042] In use, the operator places the mold on top of the base 1. Then, according to the shape of the mold, the motor 471 is started. The forward rotation of the motor 471 drives the first bevel gear 473 and the third bevel gear 475 on the rotating shaft 472 to rotate. The first bevel gear 473 drives the two second bevel gears 474 to rotate. The two second bevel gears 474 drive the two first lead screws 43 to rotate. The first lead screws 43 drive the two arc-shaped clamping blocks 42 to move in opposite directions along the guide rod 48 through the first clamping plate 41. At the same time, the third bevel gear 445 drives the two fourth bevel gears 476 to rotate. The two fourth bevel gears 476 drive the two second lead screws 46 to rotate. The second lead screws 46 drive the two planar clamping blocks 45 to move in opposite directions along the sliding groove 410 through the slider 49 at the bottom of the second clamping plate 44. The two arc-shaped clamping blocks 42 clamp the mold, preventing it from being unstable and thus not directly affecting the detection operation of the detection device, while also preventing the detection results from being compromised. The problem of inaccuracy is addressed by reversing the direction of motor 471, which drives two planar clamping blocks 45 to clamp the mold. Different clamping blocks can be used to clamp molds with different appearances, improving the applicability of the detection device. Then, the mold is inspected by the detection component 3. When the clamping blocks are worn or damaged, the operator squeezes the pull plate 510, which pushes the push rod 56 to move. The push rod 56 compresses the second spring 58 through the pressure plate 57, generating tension. The tension of the second spring 58 drives the push rod 56 back to its initial position. Then, the push rod 56 pushes the pin shaft 52 along the guide block 59 to disengage from the limiting hole 54 and retract into the receiving hole 51. It also compresses the first spring 53, generating tension. The tension of the first spring 53 pushes the pin shaft 52 back to its initial position. Then, the arc-shaped clamping block 42 is removed from the first clamping plate 41 for easy replacement of the clamping block, saving a lot of time and improving work efficiency.
