Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding technology, specifically to an injection mold with a locking structure. Background Technology
[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.
[0003] According to Chinese Patent Publication No. CN218171190U, in the above application, the rotating threaded column drives the moving plate to move inward, so that one end of the pin is inserted into the inner cavity of the square slot, connecting the moving plate and the upper injection mold, thereby connecting the upper injection mold with the sliding ring. The sliding fit between the sliding ring and the sliding column limits the upper injection mold, thereby guiding the movement of the upper injection mold and improving the practicality of the injection mold with the guiding structure.
[0004] However, in actual use, the above-mentioned equipment causes deformation of the mold due to the high pressure during injection molding, which affects product quality. In view of this, we propose an injection mold with a locking structure. Utility Model Content

[0007] Preferably, the support block has receiving grooves on both sides that are adapted to the electric telescopic rod and the locking block.
[0008] Preferably, the inclination of the lower surface of the card block is the same as the inclination of the bottom of the receiving groove opened on both wings of the reinforcing block.

[0019] 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 scope of protection of the present utility model.
[0020] like Figure 1-3 As shown, this utility model provides a technical solution: an injection mold with a locking structure, including a lower template 1, a limiting post 2 fixedly connected to the surface of the lower template 1, a support block 3 fixedly connected to the lower surface of the lower template 1, receiving grooves adapted to the electric telescopic rod 4 and the locking block 5 on both sides of the support block 3, an electric telescopic rod 4 fixedly connected to one side of the support block 3, and a locking block 5 fixedly connected to one end of the electric telescopic rod 4. The inclination of the lower surface of the locking block 5 is the same as the inclination of the bottom of the receiving grooves opened on both wings of the reinforcing block 7. By setting the electric telescopic rod 4 and the locking block 5, in conjunction with the reinforcing block 7, the function of strengthening the upper template 6 is achieved, thus solving the problem of mold deformation caused by high pressure, which affects product quality. An upper template 6 is set above the lower template 1, and limiting holes adapted to the limiting post 2 are opened at the four corners of the upper template 6. The upper template 6 has a receiving groove on one side that matches the blocking strip 13. A reinforcing block 7 is fixedly connected to the upper surface of the upper template 6. An injection port 8 is provided on the upper surface of the upper template 6. A venting hole 9 is provided on the surface of the injection port 8. A leak-proof plate 10 is fixedly connected to the lower surface of the upper template 6. The leak-proof plate 10 matches the receiving groove inside the lower template 1. A connecting block 11 is fixedly connected to one side of the upper template 6. An electric push rod 12 is fixedly connected to one side of the connecting block 11. A blocking strip 13 is fixedly connected to one end of the electric push rod 12. One end of the blocking strip 13 is fixedly connected to one end of the electric push rod 12. The other end of the blocking strip 13 matches the venting hole 9. By setting the venting hole 9, the connecting block 11, the electric push rod 12, and the blocking strip 13, the functions of venting and leak prevention are achieved, thus solving the problem of effective injection of internal gas during the injection molding process.
[0021] Working principle: When the injection mold with locking structure is used, when the upper mold plate 6 descends, the anti-leakage plate 10 can be accurately locked into the receiving groove inside the lower mold plate 1 due to the action of the limiting post 2. Then, the electric telescopic rod 4 is activated to push the locking block 5 towards the reinforcing block 7. Since the locking block 5 is lower than the receiving grooves on both sides of the reinforcing block 7, it will exert a downward pressure on the reinforcing block 7, thereby reinforcing the upper mold plate 6 and preventing the mold from deforming due to high pressure during injection. During the injection process, the vent hole 9 is opened to prevent gas in the mold plate from preventing the product from being completely injected. When the injection is completed, the electric push rod 12 is activated, which drives the blocking strip 13 to block the vent hole 9 to prevent liquid plastic leakage.
[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
