[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 hardware mold mold frame positioning device comprises a workbench 1, a mounting plate 2 is fixedly connected to the top of the workbench 1, a lower mold 3 is fixedly connected to the top of the workbench 1, an upper mold 4 is arranged on the front of the mounting plate 2, two electric push rods 5 are fixedly connected to the mounting plate 2, the bottom ends of the two electric push rods 5 are fixedly connected to the upper mold 4, the left and right sides of the upper mold 4 are fixedly connected with positioning plates 6, two through holes 7 are provided on the two positioning plates 6, and limiting rods 8 are provided inside the four through holes 7, and the two ends of the four limiting rods 8 are respectively fixedly connected to the workbench 1 and the mounting plate 2, and the bottoms of the two positioning plates 6 are fixedly connected to two fixing blocks 9, the four fixing blocks 9 are provided with square grooves 10, and the four fixing blocks 9 are provided with clamping structures 11.

[0027] The clamping structure 11 includes four sliding rods 111, one ends of the four sliding rods 111 are inserted into the fixed block 9 and slidably connected thereto, the four sliding rods 111 are sleeved with springs 112, the two ends of the four springs 112 are respectively fixedly connected to the four sliding rods 111 and the fixed block 9, one end of the four sliding rods 111 close to the limiting rod 8 is fixedly connected with a slider 113 slidably connected to the limiting rod 8, the fixed block 9 is sleeved with a lifting ring 114 threadedly connected thereto, and a driving groove 115 in contact with the sliding rod 111 is provided at the bottom of the lifting ring 114, and the driving groove 115 is shaped like a trumpet.

[0028] In the utility model, the upper mold 4 is driven to descend and engage with the lower mold 3 by the electric push rod 5. During the descent of the upper mold 4, the two positioning plates 6 will drive the fixed block 9 to descend. Four sliding bars 111 are arranged on the fixed block 9. The end of the sliding bar 111 on each fixed block 9 away from the limiting rod 8 is tightly attached to the driving groove 115 on the lifting ring 114. The driving groove 115 will limit the sliding bar 111, so that the sliding block 113 fixedly connected to the other end of the sliding bar 111 always keeps in contact with the limiting rod 8. During the descent of the upper mold 4, the sliding block 113 on each fixed block 9 will slide along the corresponding surface of the limiting rod 8, so as to realize the positioning of the descending direction of the upper mold 4, so that the upper mold 4 can be accurately engaged with the lower mold 3, and thus complete the positioning of the upper mold 4.

[0029] After long-term use, the slider 113 causes wear to the limit rod 8, and a gap appears between the slider 113 and the limit rod 8. The user only needs to rotate the lifting ring 114, and the lifting ring 114 will descend along the surface of the fixed block 9. During the descent of the lifting ring 114, the driving groove 115 will be driven to squeeze the sliding rod 111. After the sliding rod 111 is squeezed, it will deviate. After the sliding rod 111 deviates, it will compress the spring and drive the slider 113 to approach the limit rod 8 until the slider 113 is tightly attached to the limit rod 8 again, thereby compensating for the gap between the slider 113 and the limit rod 8, overcoming the influence of wear on the lowering positioning of the upper mold 4, improving the accuracy of the engagement between the upper mold 4 and the lower mold 3, and improving the qualified rate of product production.

[0030] See also Figure 3 , wherein: a ball 12 movably connected to the sliding rod 111 and away from the limiting rod 8 is embedded at one end thereof, and the surface of the ball 12 is in contact with the driving groove 115 .

[0031] In the present invention, the arrangement of the ball bearing 12 can reduce the wear between the slide bar 111 and the driving groove 115, thereby increasing the service life of the device.

[0032] See also Figure 3 , wherein: a roller 13 rotatably connected to the slider 113 is embedded on the slider 113 , and the outer side of the roller 13 is in contact with the limiting rod 8 .

[0033] In the utility model, by setting the roller 13, the friction between the slider 113 and the limit rod 8 can be reduced, the smoothness of the descent of the upper mold 4 can be improved, the wear can be reduced, and the cycle of adjusting the slider 113 can be shortened, thereby improving the practicality of the device.

[0034] See also Figure 1 and 4 , wherein: a liquid storage tank 14 is opened on the limiting rod 8, a ring-shaped smear sponge 15 is embedded on the outer side of the limiting rod 8, an oil-absorbing sponge 16 is fixedly connected to the bottom of the smear sponge 15, and the bottom of the oil-absorbing sponge 16 passes through the limiting rod 8 and contacts with the inner wall of the liquid storage tank 14.

[0035] In the utility model, lubricating oil is stored in the liquid storage tank 14, and the oil-absorbing sponge 16 can absorb the lubricating oil. The absorbed lubricating oil will be absorbed by the smear sponge 15. After the upper mold 4 moves up and down repeatedly for many times, the user drives the upper mold 4 to rise, and the roller 13 will rise along the limiting rod 8. The roller 13 will roll on the smear sponge 15, and the smear sponge 15 will smear the lubricating oil on the roller 13, thereby further reducing the friction between the slider 113 and the limiting rod 8, improving the smoothness of the descent of the upper mold 4, reducing wear and shortening the cycle of adjusting the slider 113, thereby improving the practicality of the device.

[0036] See also Figure 1 , wherein: a controller 17 is fixedly connected to the top of the workbench 1 , and an output end of the controller 17 is connected to a signal of the electric push rod 5 .

[0037] In the present invention, the arrangement of the controller 17 can facilitate the user to control the opening and closing of the electric push rod 5, thereby improving the practicality of the device.

[0038] The above are the 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.
