Description

Technical Field

[0001] The present invention relates to the technical field of clamping machines, and specifically to a disk vertical clamping machine for precision mold production. Background Art

[0002] As product designs become larger and larger, molds are also getting larger. Therefore, it is impossible to assemble molds solely by manpower, and hydraulic clamping machines can assemble large molds.

[0003] Existing clamping machines rely on the uniform suction force of electromagnetic plates to fix molds. If there is magnetic field distortion, it may cause uneven stress on the molds, resulting in deformation after clamping. Moreover, the unshielded stray magnetic field over a long period may cause residual magnetism in metal components such as mold sliders, leading to dust adsorption and movement jamming, affecting the use of the disk vertical clamping machine for precision mold production. If the mold installation position is offset, local collisions or uneven stress may occur during clamping, resulting in damage to the mold cavity, guide pillars or inserts. At the same time, it may cause the clamping force to concentrate in a local area, resulting in uneven stress on the electromagnetic chuck and affecting the equipment life. It is difficult for the existing technology to position the mold, reducing production efficiency and increasing debugging time. Finally: Some precision molds need to withstand high-pressure material filling or impact force during production. It is difficult for the existing technology to simulate the load conditions in actual production and detect weak links in mold design or manufacturing in advance, which may lead to cracking or wear of the mold due to overload during formal production. Moreover, when the mold is clamped, if the stress is uneven, it may cause local deformation. It is difficult for the existing technology to make up for the uneven distribution of disk magnetic force, and the practicability is relatively single. Finally: When an abnormality occurs, it is difficult for the existing technology to immediately cut off the power source to avoid damage caused by mechanical movement. And if it is detected that the mold is not aligned during the clamping process, it is difficult for the existing technology to prevent the mold from colliding, thus it is difficult to protect high-precision cavities and inserts.

[0023] The shielding mechanism 5 includes a first electromagnetic block 51. The first electromagnetic block 51 is magnetically adsorbed on the top of the first electromagnetic plate 4. A first installation shell 52 is magnetically adsorbed on the top of the first electromagnetic block 51.

Cylinders 55 are fixedly connected to the four circumferences of the top of the second electromagnetic block 53. A clamping plate 56 is fixedly connected to the back of the cylinder 55 on the front side of the top of the second electromagnetic block 53. The cylinder 55 is convenient for driving the clamping plate 56 to move.

[0025] A electromagnetic shielding cloth 57 is fixedly connected below the front end of the clamping plate 56. The electromagnetic shielding cloth 57 is wound around the outer wall of the reel 58. Fifth electromagnetic blocks 59 are magnetically adsorbed at both the left and right ends of the reel 58. The electromagnetic shielding cloth 57 penetrates through the first mounting shell 52 and is slidably connected to its interior. The electromagnetic shielding cloth 57 facilitates the formation of an electromagnetic barrier.

[0026] The fifth electromagnetic blocks 59 are fixedly connected to the inner bottom of the first mounting shell 52. The first electromagnetic block 51, the second electromagnetic block 53, and the fifth electromagnetic blocks 59 are all electrically connected to an external current output device.

[0027] The working principle of a disk vertical die closing machine for precision mold production based on Embodiment 1 is as follows: First, when using this device, first place this device in the working area, and then connect the device to an external power supply to provide the power required for the operation of this device. Second, the staff respectively place the upper mold 6 and the lower mold 9 on the first electromagnetic plate 4 and the second electromagnetic plate 8. Then, after energizing them, the upper mold 6 and the lower mold 9 are attracted by the first electromagnetic plate 4 and the second electromagnetic plate 8. In the die closing state, the pressure of the hydraulic pump 2 is adjusted through the control panel 10, so that the upper mold 6 and the lower mold 9 can be tightly closed under high pressure. Then, the die closing state is exited, the hydraulic pump 2 decompresses, the first electromagnetic plate 4 rises and drives the upper mold 6, so that the upper mold 6 and the lower mold 9 are separated and flipped, so that the upper mold 6 and the lower mold 9 are placed side by side, and the die closing action is completed. Third, when the first electromagnetic plate 4 and the second electromagnetic plate 8 are in use, start the four groups of cylinders 55 and drive the fifth electromagnetic blocks 59 to stop working through an external current output device. Drive the four groups of clamping plates 56 to move through the four groups of cylinders 55, so that the distance between the four groups of clamping plates 56 gradually shortens. Thus, the upper mold 6 is clamped by the four groups of clamping plates 56. And during the movement of the four groups of clamping plates 56, the four groups of electromagnetic shielding cloths 57 on the outer walls of the four groups of reels 58 are synchronously pulled to move, so that the electromagnetic shielding cloths 57 open and are located between the first electromagnetic plate 4 and the second electromagnetic plate 8 during die closing. An electromagnetic barrier is formed through the electromagnetic shielding cloth 57 to balance the magnetic field distribution between the first electromagnetic plate 4 and the second electromagnetic plate 8, reduce the error of the suction uniformity, meet the parallelism requirements of the precision mold, and at the same time block the stray magnetic field through the electromagnetic shielding cloth 57, reduce the residual magnetic amount of the metal parts of the mold, and reduce the maintenance frequency.

[0028] Embodiment 2:

[0029] Please refer to Figure 4, a disk vertical die closing machine for precision mold production according to the present invention. Compared with the first embodiment, this embodiment further includes: a positioning mechanism 54. The positioning mechanism 54 includes a sliding groove 541.

Both the third electromagnetic block 542 and the fourth electromagnetic block 543 are electrically connected to an external current output device. The fourth electromagnetic block 543 is slidably connected to the inside of the sliding groove 541.

[0032] In this embodiment: When it is necessary to position the upper mold 6, the twelve groups of third electromagnetic blocks 542 are driven to work step by step through an external current output device, so that the fourth electromagnetic block 543 moves left or right under the influence of the magnetic adsorption of the twelve groups of third electromagnetic blocks 542. The fourth electromagnetic block 543 drives the installation rod 544 to move left or right. The installation rod 544 drives the rubber shock absorber 545, the cast iron integrated base 546, and the laser rangefinder 547 to move left or right. Thus, the position of the upper mold 6 is detected multiple times by the laser rangefinder 547, preventing the installation position of the upper mold 6 from shifting, and avoiding phenomena such as local collision or uneven force during die closing, improving production efficiency, reducing debugging time, and the twelve groups of third electromagnetic blocks 542 can be driven to stop working through an external current output device, so that the third electromagnetic block 542 and the fourth electromagnetic block 543 are in a non-magnetic adsorption state and separated. Furthermore, the installation rod 544, the rubber shock absorber 545, the cast iron integrated base 546, and the laser rangefinder 547 can be removed through the fourth electromagnetic block 543 to prevent it from affecting the die closing state. The fourth electromagnetic block 543 can also be magnetically adsorbed to the second electromagnetic plate 8, and then the position of the lower mold 9 can be detected by the laser rangefinder 547.
