Technical Field
[0001] This invention relates to the field of mold positioning technology, and more specifically, to a mold positioning device for die casting molds. Background Technology
[0002] As an important component of die-casting molds, the accuracy of the lower mold's installation and positioning directly affects the mold closing accuracy of the upper and lower molds, which in turn affects the dimensional accuracy, surface quality, and service life of the die-cast parts. Currently, in the traditional die-casting mold installation process, the positioning of the lower mold mainly relies on manual labor based on experience for rough placement and adjustment. However, this method has drawbacks: manual positioning is not only inefficient but also difficult to guarantee positioning accuracy, easily leading to positioning deviations and resulting in incomplete mold closing between the upper and lower molds.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0019] For an example, please refer to... Figures 1-4 The device includes a lower mold mounting plate 1. The top of the lower mold mounting plate 1 has several T-shaped grooves 101. The bottom of the lower mold mounting plate 1 is fixedly mounted with a support shaft 102. The outer surface of the support shaft 102 is fitted with a collar 2 through a bearing. The outer surface of the collar 2 is fixedly connected with a rotating plate 201. A driving component is provided on the rotating plate 201. The driving component is connected to several C-shaped frames 205. The C-shaped frames 205 are divided into two groups. Both groups of C-shaped frames 205 are connected to connecting plates 206. This application can drive the two connecting plates 206 to move by the cooperation of the driving component and the four C-shaped frames 205. When the two connecting plates 206 are close to each other, they can push the lower mold to move to the middle of the lower mold mounting plate 1 to position the lower mold. The collar 2 is connected to the support shaft 102 through the bearing, so that the collar 2, the rotating plate 201 and the driving component can rotate. Furthermore, the connecting plates 206 can also rotate around the support shaft 102 to position the lower mold on all four sides.
[0020] Furthermore, a limiting groove is provided at the bottom end of the support shaft 102, and a base plate 103 is provided at the bottom of the support shaft 102. A connecting groove 104 is provided at the top of the base plate 103 to be inserted into the limiting groove and the bottom end of the support shaft 102. The base plate 103 and the support shaft 102 are fixed together by bolts. Several mounting holes are also provided on the base plate 103. The mounting holes allow the base plate 103 to be mounted on the die-casting equipment by bolts.
[0021] Furthermore, there are four C-shaped frames 205. The driving component includes a bidirectional screw 202 mounted on the bottom of the rotating plate 201 via bearings and bearing seats. Two connecting blocks 204 are threadedly connected to the outer surface of the bidirectional screw 202. The two connecting blocks 204 are respectively connected to two of the C-shaped frames 205. A drive motor 203 is mounted on the rotating plate 201 and is connected to the bidirectional screw 202. The drive motor 203 can drive the bidirectional screw 202 to rotate. During the rotation of the bidirectional screw 202, it drives the connecting blocks 204 connected to it to move, and then drives the connecting plate 206 to move through the C-shaped frames 205.
[0022] Furthermore, the driving component also includes a support rod 210 mounted on the bottom of the rotating plate 201 via a bearing seat. The support rod 210 and the bidirectional screw 202 are located on both sides of the support shaft 102. Two connecting blocks 204 are also provided on the outer surface of the support rod 210, and a linear bearing is provided between the support rod 210 and the connecting blocks 204 thereon. The two connecting blocks 204 on the support rod 210 are respectively connected to two other C-shaped frames 205. The cooperation between the support rod 210 and the connecting blocks 204 thereon can limit the movement of the C-shaped frames 205, thereby improving the stability of the C-shaped frames 205 when they move.
[0023] Furthermore, each of the four C-shaped frames 205 is provided with a through hole 207, which corresponds to the two ends of the support rod 210 and the bidirectional screw 202, respectively, so as to prevent the C-shaped frame 205 from interfering with the bidirectional screw 202 and the support rod 210 when it moves.
[0024] Furthermore, a slide rail 208 is installed at the bottom of the rotating plate 201, and a slider 209 is slidably connected on the slide rail 208. The slider 209 is connected to the connecting block 204. The slide rail 208 and the slider 209 cooperate with each other to support and limit the connecting block 204.
[0025] Furthermore, a stop 214 is installed at the bottom of the rotating plate 201. The stop 214 is located at the outer end of the slide rail 208 and can limit the movement of the connecting block 204 to the maximum distance.
[0026] Furthermore, a fixing component is provided between the lower mold mounting plate 1 and the rotating plate 201; the fixing component includes four limiting holes 213 opened at the bottom of the lower mold mounting plate 1 and an internally threaded tube 211 installed at the bottom of the rotating plate 201. The internally threaded tube 211 is threadedly connected to a first hand-tightening bolt 212. The top end of the first hand-tightening bolt 212 passes through the rotating plate 201 and is inserted into one of the limiting holes 213. The insertion of the first hand-tightening bolt 212 into the limiting hole 213 can fix the position of the rotating plate 201.
[0027] Furthermore, a connecting shaft 301 is provided on the connecting plate 206, and a support plate 3 is sleeved on the outer surface of the connecting shaft 301 through a bearing. Two threaded holes 302 are provided on the connecting plate 206, and a second hand-tightening bolt 303 is threaded onto the support plate 3. The second hand-tightening bolt 303 is connected to one of the threaded holes 302. The support plate 3 can switch between horizontal and vertical states. During die casting and positioning, the support plate 3 is horizontal. When the upper die of die casting is raised, the support plate 3 can be raised for cleaning or maintenance of the lower die. Figure 5 As shown, the support plate 3 can play a safety protection role at this time, reducing the safety hazards caused by the accidental fall of the upper mold. The two threaded holes 302 are located above and to the side of the connecting shaft 301, respectively.
[0028] Reference Figure 1 Insert the T-bolts for installing the lower mold into the T-slot 101, place the lower mold on top of the lower mold mounting plate 1, start the drive motor 203, drive the bidirectional screw 202 to rotate, and drive the connecting block 204 connected to it to move during the rotation of the bidirectional screw 202, which in turn drives the connecting plate 206 to move through the C-shaped frame 205, and pushes the lower mold to move through the connecting plate 206 to center and position the lower mold. Then, move the connecting plate 206 away from the lower mold, loosen the first hand-tightening bolt 212 so that the first hand-tightening bolt 212 separates from the limiting hole 213, and then rotate the rotating plate 201 around the support shaft 102 to switch the position of the connecting plate 206. The drive unit continues to drive the connecting plate 206 to move, thereby positioning the lower mold in four directions. The lower mold can be fixed by using T-bolts, nuts and lower mold pressure plates.
