[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figures 1 to 4 In the utility model: a mold frame positioning device for a mold, including a base 1, a lower mold 2 is fixedly connected to the top of the base 1, an upper mold 3 is arranged above the lower mold 2, fixed plates 4 are fixedly connected to the left and right sides of the lower mold 2, two through holes 5 are provided on the two fixed plates 4, and top plates 6 are detachably connected to the left and right sides of the upper mold 3. Two limiting rods 7 are fixedly connected to the bottoms of the two top plates 6. The bottom ends of the four limiting rods 7 are respectively located inside the four through holes 5, and the inner walls of the four through holes 5 are embedded with annularly distributed balls 8, and the outer sides of the balls 8 are in contact with the limiting rods 7.

[0027] In the utility model, when in use, the upper mold 3 is driven by the lifting device to move toward the lower mold 2. During the process, the limit rods 7 on the left and right sides of the upper mold 3 will slide in the through holes 5. The cooperation between the limit rods 7 and the through holes 5 can limit the descent of the lower mold 2, and the setting of the ball 8 can convert the sliding friction between the limit rods 7 and the through holes 5 into rolling friction, which effectively reduces wear and improves the service life of the device.

[0028] See also Figure 4 , wherein: two cavities 9 are provided on the fixed plate 4, the two cavities 9 are both arranged in a circular ring shape, the inner walls of the two cavities 9 are fixedly connected with oil suction rings 10, the tops of the two oil suction rings 10 are fixedly connected with smear rings 11, and the tops of the two smear rings 11 are in contact with the ball 8.

[0029] In the utility model, lubricating oil is added to the inside of the cavity 9, and the oil suction ring 10 can absorb the lubricating oil. Then the smearing ring 11 is an oil-absorbing sponge. The smearing ring 11 will absorb the lubricating oil on the oil suction ring 10. Since the inner ring of the smearing ring 11 is in contact with the ball 8, the smearing ring 11 will smear the lubricating oil on the surface of the ball 8, thereby achieving the effect of oiling the ball 8. The limiting rod 7 will automatically oil the ball 8 when it slides in the through hole 5, further reducing the friction and reducing the service life of the wear-promoting device.

[0030] See also Figure 4 , wherein: a refueling hole 12 is opened on the inner wall of the cavity 9, and a sealing plug 13 is fixedly connected to the inner wall of the refueling hole 12.

[0031] In the present invention, the user inserts a syringe filled with lubricating oil into the sealing plug 13, and can add the lubricating oil into the cavity 9, thereby achieving the effect of adding oil to the cavity 9, thereby improving the practicality of the device.

[0032] See also Figures 1 to 3, wherein: the left and right sides of the upper mold 3 are fixedly connected with support plates 14, the tops of the two top plates 6 are inserted with two bolts 15 rotatably connected thereto, and the bottom ends of the four bolts 15 are respectively inserted into the two support plates 14 and threadedly connected thereto.

[0033] In the utility model, the top plate 6 can be fixed on the support plate 14 by setting the bolt 15, so as to fix the limit rod 7. The limit rod 7 will be worn after working for a certain period of time. At this time, the user can rotate the bolt 15 to remove the top plate 6 and replace the limit rod 7, thereby improving the practicality of the device.

[0034] See also Figures 1 to 3 , wherein: the two limit rods 7 are both sleeved with an organ pipe 16 fixedly connected thereto, and the bottom end of the organ pipe 16 is fixedly connected to the fixing plate 4.

[0035] In the utility model, the arrangement of the organ pipe 16 can prevent the limit rod 7 from dust, thereby preventing dust from adhering to the limit rod 7, thereby improving the practicability of the device.

[0036] See also Figures 1 to 3 , wherein: the left and right sides of the base 1 are fixedly connected with installation boxes 17, the tops of the two installation boxes 17 are provided with two dustproof holes 18 adapted to the through holes 5, and the inner bottom walls of the two dustproof holes 18 are installed with pressure sensors 19.

[0037] In the present invention, the setting of the dustproof hole 18 can prevent dust from adhering to the limit rod 7, thereby improving the practicability of the device, and after the upper mold 3 and the lower mold 2 are fitted together, the bottom end of the limit rod 7 will squeeze the pressure sensor 19, and the pressure sensor 19 will measure a data. When the data is stable, it means that the limit rod 7 is in normal use. If the limit rod 7 is worn, the limiting effect of the limit rod 7 on the upper mold 3 is reduced, and the limit rod 7 will be inserted into the dustproof hole 18 at an angle. The contact between the limit rod 7 and the dustproof hole 18 will consume part of the force of the upper mold 3 descending, so the data detected by the pressure sensor 19 will become smaller. The user can assist in judging the wear condition of the limit rod 7 by observing the size of the detected data, thereby facilitating the replacement of the limit rod 7 as soon as possible, thereby improving the practicability of the device.

[0038] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
