Technical Field

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

[0002] The mold frame is the semi-finished skeleton of the mold, which is composed of steel plates, guiding mechanisms, ejection systems and other parts, providing the installation foundation and movement guarantee for the mold core (forming part).

[0003] Existing mold bases require angled holes during machining to allow angled ejector pins to pass through and eject the formed workpiece. However, machining these angled holes necessitates first fixing the mold base to the worktable of the machining equipment before machining the holes, which is cumbersome and inefficient. Furthermore, lubrication between the ejector pin and the hole requires repeatedly moving the ejector pin to one end, applying lubricant to the contact area, and then moving it to the other end to apply lubricant again, resulting in a tedious and ineffective process. Therefore, we propose a mold base structure with an angled hole insert.

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

[0026] Please see Figure 1 - Figure 4 This embodiment of a mold frame structure with an inclined hole insert includes a mold frame body 1. The top of the mold frame body 1 has a groove 2, the groove 2 has an insert 3 inside, the top of the insert 3 has an inclined hole 8, and the inclined hole 8 has an inclined push rod 4 coaxially inside the inclined hole 8. One end of the inclined push rod 4 extends to the outside of the inclined hole 8. In actual use, by opening the groove 2 on the mold frame body 1 and connecting it with the insert 3, the inclined push rod 4 can be connected to the mold frame body 1. It is not necessary to directly open the inclined hole 8 on the mold frame body 1 to connect it with the inclined push rod 4. The processing is simple and the use is convenient.

[0027] It should be noted that a through groove 20 is provided at the bottom of the groove 2, and the other end of the inclined ejector rod 4 passes through the through groove 20 and is connected to the drive mechanism. After the workpiece is formed and processed, the inclined ejector rod 4 can be moved by the drive mechanism to eject the workpiece and complete the demolding of the workpiece.

[0028] like Figure 1 and Figure 3 As shown, stepped holes 9 are provided at both ends of the top of the insert 3. Each stepped hole 9 is provided with a first fastening bolt 5. A threaded hole 19 is provided at the bottom of the groove 2. The bottom of each first fastening bolt 5 passes through the corresponding stepped hole 9 and extends into the corresponding threaded hole 19. The bottom of each first fastening bolt 5 is threadedly connected to the threaded hole 19. In actual use, by passing the first fastening bolt 5 through the stepped hole 9 and screwing it into the threaded hole 19, the insert 3 can be fixed in the groove 2 and secured firmly.

[0029] It should be noted that, as Figure 3 As shown, when the first fastening bolt 5 is tightened, the top of the first fastening bolt 5 is located inside the stepped hole 9, so that the installation of the first fastening bolt 5 will not hinder the installation of the subsequent core components of the mold.

[0030] It should be noted that the side wall of the insert 3 is fitted with the inner wall of the groove 2 with a clearance, so that the insert 3 will not wobble after being placed in the groove 2I.

[0031] It should be noted that when the insert 3 is located in the groove 2, the top of the insert 3 is flush with the top opening of the groove 2, so that the installation of the insert 3 will not hinder the subsequent installation of the core components of the mold.

[0032] like Figure 1 and Figure 3 As shown, one side of the insert 3 is set as an inclined surface 11, and a limiting inclined block 10 is installed on one side of the groove 2. The limiting inclined block 10 matches the inclined surface 11. In actual use, the insert 3 can be limited by the cooperation of the limiting inclined block 10 and the inclined surface 11, so that the insert 3 is installed more stably.

[0033] like Figure 1 and Figure 3 As shown, a fixing plate 14 is installed on one side of the top of the limiting inclined block 10. A groove 12 is also provided inside the mold frame body 1. One end of the fixing plate 14 extends into the groove 12 and is fastened to the groove 12 by bolts. In actual use, the fixing plate 14 can be fixed in the groove 12 by bolts, thereby fixing the limiting inclined block 10 in the groove 2, which is fixed and stable.

[0034] like Figure 3 and Figure 4 As shown, an oil reservoir 15 is provided on one side of the top of the insert 3, and a guide groove 13 is provided at one end of the bottom of the oil reservoir 15. Several annular grooves 17 are provided on the side of the inclined hole 8. The annular grooves 17 are connected to each other through the guide grooves 13. In actual use, when it is necessary to lubricate the inclined push rod 4, the operator can pour the lubricating oil into the oil reservoir 15. The lubricating oil can flow into the annular grooves 17 along the guide grooves 13 under the action of gravity, and finally contact the side of the inclined push rod 4 to lubricate the inclined push rod 4 and the inclined hole 8.

[0035] like Figure 3 and Figure 4 As shown, the top of the oil storage tank 15 is provided with a receiving groove 16, and the inside of the receiving groove 16 is provided with a cover plate 7. The cover plate 7 covers the end of the oil storage tank 15, and the edge of the cover plate 7 is fastened to the bottom of the receiving groove 16 by the second fastening bolt 6. In actual use, the cover plate 7 can be fixed in the receiving groove 16 by the second fastening bolt 6 to block the opening of the oil storage tank 15, prevent external dust from seeping into the oil storage tank 15, and improve the dustproof effect.

[0036] like Figure 4 As shown, a sealing plug 18 is installed at the bottom of the cover plate 7. When the cover plate 7 is located in the receiving groove 16, the bottom of the sealing plug 18 extends into the oil storage tank 15 and is sealed to the side wall of the oil storage tank 15. The opening of the oil storage tank 15 can be sealed by the sealing plug 18 to prevent dust and other impurities from entering the oil storage tank 15, thereby further improving the dustproof effect.

[0037] The working principle of the above embodiments is as follows:

[0038] During installation, the worker places the insert 3 into the groove 2. At this time, the stepped hole 9 on the insert 3 is aligned with the threaded hole 19 at the bottom of the groove 2. Then, the first fastening bolt 5 is passed through the stepped hole 9 and inserted into the threaded hole 19. Tightening the first fastening bolt 5 will fix the insert 3 in the groove 2. Then, the limiting inclined block 10 is placed into the groove 2, so that the limiting inclined block 10 abuts against the inclined surface 11 on the insert 3. Then, the fixing plate 14 is fixed in the groove 12 to fix the limiting inclined block 10. The installation of the insert 3 is then completed. Then, the inclined push rod 4 is connected to the mold frame body 1. The connection is secure and stable. This way, only the inclined hole 8 needs to be made on the insert 3 to connect with the inclined ejector rod 4. There is no need to make the inclined hole 8 on the mold frame body 1. The processing is convenient and the use effect is improved. When the inclined ejector rod 4 needs to be lubricated, the operator opens the cover plate 7 and then injects lubricating oil into the oil storage tank 15. The lubricating oil will flow into the annular groove 17 along the guide groove 13 under the action of gravity, and finally adhere to the surface of the inclined ejector rod 4 to lubricate the inclined ejector rod 4 and the inclined hole 8. The lubrication is convenient and the use effect is improved. After lubrication, the cover plate 7 is placed in the receiving groove 16 and fixed with bolts.

[0039] 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.

[0040] 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.
