[0026] Figure 1-4 As one embodiment of the utility model, an adjustable support column of an injection mold comprises a base plate 1, a plurality of support columns 2 are arranged on the base plate 1, a same movable plate 3 is mounted on the upper surface of the support columns 2, and an adjustment mechanism 4 for adjusting the height of the support columns 2 is arranged on the upper surface of the base plate 1;

[0027] The adjustment mechanism 4 includes two symmetrically arranged fixing plates 41 fixed on the upper surface of the bottom plate 1. The fixing plates 41 are provided with through holes, and a rotating rod 42 is inserted into the through holes. A plurality of gears 43 are slidably connected to the outer circumferential surface of the rotating rod 42. The number of the gears 43 is the same as the number of the supporting columns 2. The supporting columns 2 are provided with racks 22 meshing with the gears 43.

[0028] The adjustment mechanism 4 further includes a control component 44 for rotating the rotating rod 42 , and a positioning component 45 disposed on the sides of the fixing plate 41 and the gear 43 for positioning the gear 43 and the rotating rod 42 .

[0029] During actual use, when it is necessary to adjust the height of the support column 2 according to the actual situation of the injection mold support column 2, the rotating rod 42 is inserted into the through-holes of the two fixed plates 41, and the gear 43 is sleeved on the outer circular surface of the rotating rod 42 according to the number of support columns 2. The gear 43 is moved to the side of the corresponding support column 2, so that the rack 22 is meshed with the gear 43, so that the gear 43 can drive the rack 22 to move when it rotates, which is convenient for installing suitable rotating rods 42 and gears 43 according to the actual number and position of support columns 2, and the heights of multiple support columns 2 can be adjusted synchronously to improve the adjustment efficiency.

[0030] More specifically, the support column 2 includes a support seat 21 fixed on the upper surface of the base plate 1, a rack 22 is slidably connected in the support seat 21, a support tube 23 is slidably connected on the outer circular surface of the support seat 21, and the top of the support tube 23 and the rack 22 are fixed on the lower surface of the movable template 3.

[0031] During the process of adjusting the height of the support column 2, the rack 22 is meshed with the gear 43, and the rack 22 moves upward under the drive of the gear 43, so that the movable template 3 moves upward, and the support tube 23 slides on the outer circular surface of the support seat 21 under the drive of the movable template 3 to protect the rack 22.

[0032] More specifically, a guide strip 46 is fixed on the outer circumferential surface of the rotating rod 42, and an axial hole matched with the rotating rod 42 is provided on the gear 43, which is used to guide and limit the gear 43; when the gear 43 is installed according to the actual situation of the support column 2, the gear 43 slides on the outer circumferential surface of the rotating rod 42, and the guide strip 46 is provided on the outer circumferential surface of the rotating rod 42 to guide and limit the sliding of the gear 43, so that when the rotating rod 42 rotates, it can drive the gear 43 on the rotating rod 42 to rotate, thereby realizing the adjustment of the support column 2.

[0033] Specifically, the control component 44 includes a worm 441 rotatably connected to the upper surface of the base plate 1, and a worm wheel 442 meshing with the worm 441 is slidably connected to the outer circumferential surface of the rotating rod 42; in actual use, when the height of the support column 2 needs to be adjusted, the worm 441 is rotated. Since the worm wheel 442 and the rotating rod 42 are slidably connected, and the worm wheel 442 is guided and limited by the guide bar 46, the worm wheel 442 is driven to rotate, and the rotating rod 42 is driven by the worm wheel 442, so that the other gears 43 on the outer circumferential surface of the rotating rod 42 rotate, driving the rack 22 to move, thereby adjusting the height of the support column 2.

[0034] Specifically, the positioning component 45 includes a fixing block 451, on the outer side of which a bolt 452 is threadedly connected, and the end of the bolt 452 passes through the fixing block 451 and is fixed with a positioning plate 453, which is used to realize the positioning of the gear 43 and the rotating rod 42; in actual use, when the position of the gear 43 or the rotating rod 42 is fixed according to the actual situation of the support column 2 on the injection mold, taking the fixing of the gear 43 as an example, the gear 43 is made to slide on the rotating rod 42, and when it slides to a suitable position, the bolt 452 is rotated to move its end downward, and the bolt 452 drives the positioning plate 453 to move downward until it contacts the surface of the guide bar 46, and the friction between the positioning plate 453 and the guide bar 46 is used to realize the positioning of the position of the gear 43.

[0035] More specifically, an anti-skid pad 454 is fixed to the lower surface of the positioning plate 453, and the anti-skid pad 454 is made of rubber. The anti-skid pad 454 is located directly above the guide bar 46. In actual use, when the positioning plate 453 is moved by rotating the bolt 452 to achieve positioning of the position of the gear 43, the anti-skid pad 454 made of rubber is arranged on the lower surface of the positioning plate 453. The friction between the anti-skid pad 454 and the guide bar 46 can be increased, thereby stabilizing the position of the gear 43.
