Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, specifically a mold frame device with a clearance structure. Background Technology

[0002] The mold frame is the basic support structure and standardized skeleton of the mold. It constitutes the main framework of the entire mold and provides a precise installation and positioning platform, stable support, reliable guidance and efficient motion transmission for the core forming components and various functional mechanisms of the mold.

[0003] Existing mold bases typically have slots on their surfaces to install the core molding inserts. However, because the slots on existing mold bases lack protective mechanisms such as clearance structures, the inserts are easily scratched or damaged by impacts, resulting in poor protection. Furthermore, during installation, the inserts are usually bolted to the mold base, and pressure plates are used on the bolts to prevent them from coming loose. However, the inserts vibrate when subjected to impacts during use, which can cause the bolts to loosen, resulting in poor installation.

[0004] Therefore, a mold frame with a clearance structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mold frame with a clearance structure, which can solve the problem of easy damage to inserts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mold frame with a clearance structure, comprising a mold frame body, wherein a second groove is provided on the top of the mold frame body, and a plurality of first grooves are provided on the top edge of the mold frame body, wherein a block is provided inside the first groove and the second groove.

[0007] The first groove is stepped, and clearance grooves are provided at the corners of the first groove and the second groove.

[0008] The bottom of both the first and second recesses is provided with receiving grooves, and each receiving groove is provided with a buffer block inside;

[0009] Each of the first slots has threaded holes at both ends and at the corner of the second slot. Each threaded hole has a fixing bolt above it. When the insert is located inside the corresponding first slot and second slot, one end of the fixing bolt passes through the edge of the insert and moves into the threaded hole and is threadedly connected to the threaded hole.

[0010] The first groove has several first recesses at both ends, and each first recess has a first elastic pressure plate inside, with the top of the first elastic pressure plate abutting against the bottom of the insert.

[0011] The bottom edge of the second groove is provided with a number of second grooves, and each second groove is provided with a second elastic pressure plate inside, the top of the second elastic pressure plate abutting against the bottom of the insert.

[0012] Preferably, the clearance groove is arc-shaped.

[0013] Preferably, the top edge of the mold frame body is set as a first rounded corner, and the edges of the first groove and the second groove are both set as second rounded corners.

[0014] Preferably, both the first elastic pressure plate and the second elastic pressure plate are supported by elastic metal materials, and both the first elastic pressure plate and the second elastic pressure plate are arranged in a "Z" shape.

[0015] Preferably, when the first elastic pressure plate and the second elastic pressure plate are not under force, the top of the first elastic pressure plate extends to the outside of the first groove, and the top of the second elastic pressure plate extends to the outside of the second groove.

[0016] Preferably, the top edge of the mold frame body has several positioning holes.

[0017] Preferably, the buffer block is made of soft copper or polyimide (PI) material.

[0026] 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. Example

[0027] Please see Figure 1 - Figure 4 In this embodiment, a mold frame with a clearance structure includes a mold frame body 1. The top of the mold frame body 1 is provided with a second groove 14, and the top edge of the mold frame body 1 is provided with a plurality of first grooves 11. Both the first grooves 11 and the second grooves 14 are provided with inserts. By placing the inserts in the corresponding first grooves 11 and second grooves 14, the first grooves 11 and second grooves 14 can horizontally limit the inserts and connect the inserts to the mold frame body 1.

[0028] like Figure 1 and Figure 2 As shown, the first groove 11 is stepped, and a clearance groove 7 is provided at the corners of the first groove 11 and the second groove 14. The clearance groove 7 is arc-shaped, which makes the corners of the first groove 11 and the second groove 14 arc-shaped. This can avoid stress concentration and prevent the surface of the insert from being scratched by the corners of the first groove 11 and the second groove 14 when installing the insert.

[0029] It should be noted that, as Figure 1 and Figure 2 As shown, the top edge of the mold frame body 1 is set as a first rounded corner 2, and the edges of the first groove 11 and the second groove 14 are both set as second rounded corners 13. The second rounded corners 13 can form the edges of the first groove 11 and the second groove 14 into an arc shape. In this way, when installing the insert, the arc surface of the second rounded corner 13 will not scratch the surface of the insert, thus improving the performance.

[0030] like Figure 1 and Figure 3As shown, the bottom of the first groove 11 and the second groove 14 are provided with a receiving groove 10. Each receiving groove 10 is provided with a buffer block 5. The buffer block 5 is made of soft copper or polyimide (PI) material. The buffer block 5 can buffer the impact force on the insert, prevent the insert from being damaged due to excessive force, and improve the protection effect.

[0031] like Figure 1 and Figure 2 As shown, threaded holes 9 are provided at both ends of the interior of each first groove 11 and at the corner of the second groove 14. A fixing bolt 4 is provided above each threaded hole 9. When the insert is located inside the corresponding first groove 11 and second groove 14, one end of the fixing bolt 4 passes through the edge of the insert and moves into the threaded hole 9 and is threadedly connected to the threaded hole 9. In actual use, by passing the fixing bolt 4 through the mounting hole on the surface of the insert and threading it with the threaded hole 9, the insert can be fixed in the corresponding first groove 11 and second groove 14, and it is fixed firmly.

[0032] like Figure 1 and Figure 2 As shown, the first groove 11 has several first grooves 12 at both ends, and each first groove 12 has a first elastic pressure plate 6 inside. The top of the first elastic pressure plate 6 abuts against the bottom of the insert. The bottom edge of the second groove 14 has several second grooves 15, and each second groove 15 has a second elastic pressure plate 8 inside. The top of the second elastic pressure plate 8 abuts against the bottom of the insert. Both the first elastic pressure plate 6 and the second elastic pressure plate 8 are made of elastic metal material. In actual use, the insert will squeeze the first elastic pressure plate 6 or the second elastic pressure plate 8 when it is installed, causing the first elastic pressure plate 6 or the second elastic pressure plate 8 to deform. This will make the first elastic pressure plate 6 or the second elastic pressure plate 8 elastic, which can then generate a pushing force on the insert, making the connection of the fixing bolt 4 more stable and preventing it from loosening.

[0033] like Figure 4 As shown, both the first elastic pressure plate 6 and the second elastic pressure plate 8 are arranged in a "Z" shape. In this way, when the first elastic pressure plate 6 and the second elastic pressure plate 8 are deformed by compression, the top of the first elastic pressure plate 6 and the second elastic pressure plate 8 will still make full contact with the bottom of the insert and will not scratch the surface of the insert.

[0034] It should be noted that, as Figure 1 and Figure 2As shown, when the first elastic pressure plate 6 and the second elastic pressure plate 8 are not under force, the top of the first elastic pressure plate 6 extends to the outside of the first groove 12, and the top of the second elastic pressure plate 8 extends to the outside of the second groove 15. In this way, when the insert is placed in the first groove 11 or the second groove 14, the first elastic pressure plate 6 and the second elastic pressure plate 8 will be squeezed by the corresponding insert, which can generate a pushing force on the insert, so that the fixing bolt 4 is installed firmly and will not loosen.

[0035] like Figure 1 and Figure 2 As shown, the top edge of the mold frame body 1 is provided with several positioning holes 3. The positioning holes 3 can be used to cooperate with the positioning pins to complete precise assembly during assembly, ensuring the accuracy of the mold.

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

[0037] During installation, the worker places the corresponding insert into the corresponding first groove 11 or second groove 14. The insert is guided by the second rounded corner 13 during insertion, and the arc surface of the second rounded corner 13 prevents scratches on the insert surface. When the insert is moved into the corresponding first groove 11 or second groove 14, the clearance groove 7 prevents the edge of the insert from being scratched by the corner of the first groove 11 or second groove 14. After placement, the bottom of the insert contacts the top of the buffer block 5, and the buffer block 5 cushions the impact force received by the insert. To protect the insert from damage, the worker then inserts one end of the fixing bolt 4 through the mounting hole on the insert and into the corresponding threaded hole 9, and tightens the fixing bolt 4 to fix the insert in the corresponding first groove 11 or second groove 14. When tightening the fixing bolt 4, the bottom of the insert will press against the corresponding first elastic pressure plate 6 or second elastic pressure plate 8. The first elastic pressure plate 6 and the second elastic pressure plate 8 are deformed by the compression, generating a reaction force on the insert. This makes the connection of the fixing bolt 4 more stable and prevents it from loosening, thus improving the installation effect.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
