Technical Field

[0001] The utility model relates to the technical field of die carriers, in particular to a die carrier with high structural strength. Background Art

[0002] A die carrier is a support structure for carrying dies and die components, commonly found in processing fields such as injection molding, die casting, and blow molding. A die carrier usually consists of an upper template, a lower template, template supports, guide pillars, guide sleeves, pistons, and other components, which are used to support various parts of the die and cooperate with the die opening and closing, injection, cooling, and other movements.

[0003] In the existing related technologies, the following defects often exist: during the actual use of the die carrier, when relative movement occurs between the guide holes on the upper die carrier and the guide rails on the lower die carrier, friction will occur between the two. Long-term friction easily leads to blockage between the guide rails and the guide holes, and further easily leads to wear on the outer surface of the guide rails and the inner side of the guide holes. Wear will cause changes in the size and shape of the die, reducing the accuracy and stability of the die, and further affecting the service strength of the die.

[0004] Therefore, the utility model provides a die carrier with high structural strength. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Referring to Figure 1 as shown, the present utility model provides a technical solution: a mold die holder with high structural strength, including a lower die holder 1 and an upper die holder 2. Four guide rails 3 are fixedly connected to the surface of the lower die holder 1. Four guide holes 4 are evenly opened on the lower surface of the upper die holder 2. The sizes of the guide rails 3 and the guide holes 4 are adapted to each other. A coating structure 5 is provided on the surface of the upper die, and a locking structure 6 is provided on the side wall of the upper die holder 2.

[0029] The specific settings and functions of its coating structure 5 and locking structure 6 will be specifically described below.

[0030] Referring to Figures 1 - 4As shown, in this embodiment: The smearing structure 5 includes a reserved groove 51 formed in the side wall of the upper die holder 2 and communicating with the guiding hole 4. An oil storage box 52 is placed inside the reserved groove 51. A limiting ring 57 is communicated with the side wall of the oil storage box 52. The limiting ring 57 is of a hollow structure, and a number of reserved holes 58 are evenly formed inside the limiting ring 57. By providing the smearing structure 5, the flexible smearing work of the lubricating fluid between the guide rail 3 and the guiding hole 4 is facilitated, and the phenomenon that serious wear between the inner sides of the guide rail 3 and the guiding hole 4 reduces the service strength of the guide rail 3 is avoided, and to a certain extent, the service strength of the die holder is improved. A sponge ring 59 is adhesively connected to the inside of the limiting ring 57. The lubricating fluid will soak the sponge ring 59 along the reserved holes 58, facilitating the subsequent even smearing work on the guide rail 3.

[0031] A piston 53 is slidably connected to the inside of the oil storage box 52, and a sliding rod 54 is slidably connected to the inside of the oil storage box 52. The other end of the sliding rod 54 is fixedly connected to a pulling block 55. By pushing the sliding rod 54, the sliding rod 54 will drive the piston 53 to push the lubricating fluid inside the oil storage box 52. A screw rod 56 threadedly penetrates through the pulling block 55, the sliding rod 54 and the piston 53. Then, the screw rod 56 is threadedly connected to the inside of the pulling block 55, the sliding rod 54 and the piston 53, and the plugging work of the pores can be realized.

[0032] Refer to Figures 1 - 3 As shown, specifically, the locking structure 6 includes a rectangular block 61 fixedly connected to the side wall of the upper die holder 2, and a sliding frame 62 is slidably connected to the inside of the rectangular block 61. By providing the locking structure 6, the flexible disassembly work of the oil storage box 52 is facilitated, and thus the regular maintenance work of the smearing structure 5 is facilitated. A spring 63 is fixedly connected between the sliding frame 62 and the rectangular block 61. The sliding frame 62 will be sleeved outside the oil storage box 52 under the elastic force of the spring 63, and the locking work of the oil storage box 52 inside the reserved groove 51 can be realized. A limiting groove 66 is formed in the side wall of the upper die holder 2, a connecting pin 64 is fixedly connected to the side wall of the sliding frame 62, and a rotating bar 65 is rotatably connected to the side wall of the connecting pin 64. By rotating the rotating bar 65 on the connecting pin 64 and turning the rotating bar 65 into the inside of the limiting groove 66, the temporary supporting work of the position of the sliding frame 62 after being pulled can be realized.

[0033] Working principle: Before using the upper die holder 2 and the lower die holder 1, first rotate the screw rod 56 out from the inside of the pulling block 55, and pull the sliding rod 54 to move the piston 53 away from the limiting ring 57. At this time, lubricating fluid can be injected into the inner side of the oil storage box 52 through the pores on the pulling block 55, the sliding rod 54, and the piston 53. Then, thread the screw rod 56 into the inner sides of the pulling block 55, the sliding rod 54, and the piston 53 to seal the pores. Next, install the limiting ring 57 and the oil storage box 52 inside the reserved groove 51, and push the sliding rod 54. The sliding rod 54 will drive the piston 53 to push the lubricating fluid inside the oil storage box 52. The lubricating fluid will soak the sponge ring 59 along the reserved hole 58. When relative movement occurs between the guide rail 3 and the guide hole 4, relative movement will occur between the guide rail 3 and the inner side of the sponge block, thereby realizing the lubrication of the guide rail 3, reducing the friction when relative movement occurs between the guide rail 3 and the guide hole 4, and avoiding wear between the guide rail 3 and the guide hole 4. By setting the coating structure 5, it is convenient to flexibly apply the lubricating fluid between the guide rail 3 and the guide hole 4, avoiding the phenomenon that serious wear between the inner sides of the guide rail 3 and the guide hole 4 will reduce the service strength of the guide rail 3, and improving the service strength of the die holder to a certain extent.

[0034] Pull the sliding frame 62 inside the rectangular block 61. When the rotating bar 65 moves to a position corresponding to the limiting groove 66, rotate the rotating bar 65 on the connecting pin 64 and turn the rotating bar 65 into the inner side of the limiting groove 66 to temporarily support the position of the sliding frame 62 after pulling. At this time, the oil storage box 52 inside the reserved groove 51 can be taken out. After installing the oil storage box 52 inside the reserved groove 51, turn out the rotating bar 65 on the inner wall of the limiting groove 66. At this time, the sliding frame 62 will be sleeved on the outer side of the oil storage box 52 under the elastic force of the spring 63 to lock the oil storage box 52 inside the reserved groove 51. By setting the locking structure 6, it is convenient to flexibly disassemble the oil storage box 52, and further convenient for the regular maintenance of the coating structure 5.
