Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a lower template structure used in molds. Background Technology

[0002] In the field of mold manufacturing and application, the lower mold plate is a key component of the mold, and its structural rationality and convenience directly affect the mold's assembly efficiency, maintenance costs, and production quality. Traditional lower mold plate structures often have some shortcomings in the connection method between the mold body and the mold base.

[0003] Traditional lower mold plates are often connected to the mold body and mold base using bolts. During installation, operators must tighten multiple bolts individually with tools, which is not only cumbersome and time-consuming, but also requires loosening the bolts individually during disassembly. This significantly reduces mold assembly and disassembly efficiency, increasing mold maintenance time and labor costs. Especially when frequent mold body replacements are needed to adapt to different product production requirements, this inefficient assembly and disassembly method severely restricts production efficiency. Therefore, a new lower mold plate structure for molds is proposed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lower template structure for use in molds, which has advantages such as improved assembly and disassembly efficiency, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lower template structure for a mold includes a mold base and a mold body disposed on the top of the mold base. Connecting plates are fixedly connected to both the left and right sides of the mold body, and mounting components that facilitate disassembly and assembly with the mold body are provided on both the left and right sides of the mold base.

[0007] The mounting assembly includes limiting frames that are fixedly connected to the left and right sides of the mold base, respectively. Threaded blocks are slidably connected to the inner side of the limiting frames, and threaded shafts are threadedly connected to the inner side of the threaded blocks. Locking shafts are fixedly connected to the opposite side of the threaded blocks on both the left and right sides.

[0008] Furthermore, the left and right sides of the inner side of the mold base are provided with connecting cavities, and the top of the inner side of the connecting cavity is provided with an insertion port that is compatible with the connecting plate.

[0009] Furthermore, the inner side of the connecting plate is provided with a locking hole adapted to the locking shaft, and the left part of the left connecting cavity and the right part of the right connecting cavity are both provided with through holes adapted to the locking shaft.

[0010] Furthermore, the right end of the threaded shaft on the left is rotatably connected to the left side wall of the mold base, and the left end of the threaded shaft on the right is rotatably connected to the right side wall of the mold base. A torsion cap is fixedly connected to the opposite ends of the threaded shafts on both the left and right sides.

[0011] Furthermore, limit blocks are fixedly connected to both the upper and lower sides of the threaded block, and limit sliding openings adapted to the limit blocks are provided on both the upper and lower sides inside the limit frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 The lower template structure for use in a mold in this embodiment includes a mold base 1 and a mold body 2 disposed on the top of the mold base 1. Connecting plates 3 are fixedly connected to both the left and right sides of the mold body 2. The left and right sides of the mold base 1 are provided with mounting components that facilitate disassembly and assembly with the mold body 2.

[0023] Please see Figure 1 In this embodiment, the installation component includes a limiting frame 4 that is fixedly connected to the left and right sides of the mold base 1 respectively. A threaded block 5 is slidably connected to the inner side of the limiting frame 4. A threaded shaft 6 is threadedly connected to the inner side of the threaded block 5. A locking shaft 7 is fixedly connected to the opposite side of the threaded blocks 5 on both the left and right sides.

[0024] Specifically, the left and right sides of the inner side of the mold base 1 are provided with connecting cavities, and the top of the inner side of the connecting cavity is provided with an insertion port that is compatible with the connecting plate 3.

[0025] It should be noted that connecting cavities are provided on the left and right sides of the inner side of the mold base 1. Their function is to provide space for the connecting plate 3, facilitating its insertion and achieving initial positioning and connection between the mold body 2 and the mold base 1. An insertion port adapted to the connecting plate 3 is provided on the top of the inner side of the connecting cavity, allowing the connecting plate 3 to be accurately and smoothly inserted into the connecting cavity, providing a basis for subsequent locking operations.

[0026] Specifically, the inner side of the connecting plate 3 is provided with a locking hole that is compatible with the locking shaft 7, and the left part of the left connecting cavity and the right part of the right connecting cavity are both provided with through holes that are compatible with the locking shaft 7.

[0027] It should be noted that a locking hole adapted to the locking shaft 7 is provided on the inner side of the connecting plate 3. When the locking shaft 7 is inserted into the hole, the connecting plate 3 can be locked, thereby firmly fixing the mold body 2 to the mold base 1. Through holes adapted to the locking shaft 7 are provided on the left side of the left connecting cavity and the right side of the right connecting cavity, providing a channel for the movement of the locking shaft 7, allowing the locking shaft 7 to pass smoothly through the side wall of the connecting cavity and be inserted into the locking hole of the connecting plate 3 to complete the locking action.

[0028] Specifically, the right end of the left threaded shaft 6 is rotatably connected to the left side wall of the mold base 1, and the left end of the right threaded shaft 6 is rotatably connected to the right side wall of the mold base 1. Torque caps are fixedly connected to the opposite ends of the left and right threaded shafts 6.

[0029] Specifically, the upper and lower sides of the threaded block 5 are fixedly connected to the limit block 8, and the upper and lower sides of the limit frame 4 are provided with limit sliding openings that are compatible with the limit block 8.

[0030] It should be noted that the limiting block 8 slides within the limiting slide, which can limit the threaded block 5 and prevent the threaded block 5 from rotating with the threaded shaft 6 when the threaded shaft 6 rotates.

[0031] Specifically, a bracket 9 is fixedly connected to the top of the mold base 1, a cylinder 10 is fixedly connected to the inner top wall of the bracket 9, and an upper mold 11 is fixedly connected to one end of the piston rod of the cylinder 10.

[0032] It should be noted that the cylinder 10 is fixedly connected to the inner top wall of the bracket 9. The cylinder 10 serves as a power source and can drive the upper mold 11 to move up and down.

[0033] Specifically, guide plates 12 are fixedly connected to both the left and right sides of the upper mold 11, and guide rods 13 are slidably connected to the inner side of the guide plates 12.

[0034] It should be noted that the cooperation between the guide plate 12 and the guide rod 13 can guide the up and down movement of the upper mold 11, ensuring that the upper mold 11 remains stable during movement and will not deviate, thus ensuring the accuracy of mold closing and improving the quality of molded products.

[0035] Specifically, the top end of the guide rod 13 is fixedly connected to the inner top wall of the bracket 9, and the bottom end of the guide rod 13 is fixedly connected to the top of the mold base 1.

[0036] The working principle of the above embodiments is as follows:

[0037] During installation, place the mold body 2 on top of the mold base 1, align the connecting plates 3 on the left and right sides of the mold body 2 with the insertion ports on the top of the connecting cavities on the left and right sides of the mold base 1, and then move the mold body 2 downwards so that the connecting plates 3 are inserted into the connecting cavities, thus completing the initial positioning of the mold body 2 and the mold base 1.

[0038] The operator rotates the torsion caps at opposite ends of the threaded shafts 6 on both sides of the mold base 1, causing the threaded shafts 6 to rotate. Since the threaded block 5 is threadedly connected to the threaded shaft 6 and is limited by the limiting block 8 and the limiting slide, it can only move axially along the threaded shaft 6. Therefore, as the threaded shaft 6 rotates, the threaded block 5 will move closer to the connecting plate 3. The movement of the threaded block 5 causes the locking shaft 7 to move, so that the locking shaft 7 passes through the through hole in the side wall of the connecting cavity and is inserted into the locking insertion hole on the inner side of the connecting plate 3, thereby locking the connecting plate 3 in the connecting cavity and completing the installation and fixation of the mold body 2 and the mold base 1.

[0039] During disassembly, the operator rotates the torsion caps at opposite ends of the threaded shafts 6 on both sides of the mold base 1 in opposite directions, causing the threaded shafts 6 to rotate in the opposite direction. Similarly, due to the limiting effect of the threaded block 5, the threaded block 5 will move away from the connecting plate 3. The movement of the threaded block 5 causes the locking shaft 7 to move, so that the locking shaft 7 is pulled out from the locking insertion hole on the inner side of the connecting plate 3 and retracted into the through hole on the side wall of the connecting cavity, thus releasing the lock on the connecting plate 3. The mold body 2 is then moved upward, so that the connecting plate 3 is pulled out from the insertion port at the top of the connecting cavity, thereby separating the mold body 2 from the mold base 1 and completing the disassembly.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
