Detailed Implementation
[0016] 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.
[0017] Please see Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of a mirror barrel injection mold, comprising a first fixed plate 2, an electric push rod 3, a movable mold base 4, a second fixed plate 6, a feed pipe 7, an injection pipe 8, and a fixed mold base 9. The electric push rod 3 is fixedly installed in the middle of the first fixed plate 2. The movable mold base 4 is fixedly connected to the end of the electric push rod 3 away from the first fixed plate 2. The second fixed plate 6 is disposed on the outer side of the first fixed plate 2. The feed pipe 7 is fixedly installed in the middle of the second fixed plate 6. The fixed mold base 9 is fixedly installed on the inner side of the second fixed plate 6. The injection pipe 8 is fixedly installed in the middle of both ends of the fixed mold base 9 away from the feed pipe 7, and the feed pipe 7 is connected to the injection pipe 8 through the fixed mold base 9. Guide posts 5 are fixedly installed at the corners of the movable mold base 4, and the guide posts 5 are slidably inserted into the fixed mold base 9.
[0018] A mirror barrel injection mold includes a demolding part 1. The demolding part 1 includes a return spring 10, an extrusion frame 11, an extrusion sliding plate 12, an auxiliary stabilizing spring 13, a connecting plate 14, and a mold cylinder 15. The extrusion frame 11 is symmetrically arranged, and the extrusion sliding plates 12 are symmetrically arranged and distributed on the outer side of the extrusion frame 11. The return spring 10 is fixedly connected to the inner end of the extrusion sliding plate 12. The auxiliary stabilizing spring 13 is symmetrically fixedly connected to the side end of the extrusion sliding plate 12 away from the extrusion frame 11. The connecting plate 14 is fixedly connected to the side end of the auxiliary stabilizing spring 13 away from the extrusion sliding plate 12. The mold cylinder 15 is fixedly connected between the connecting plates 14.
[0019] The extrusion frame 11 is fixedly connected to the first fixed plate 2.
[0020] The extrusion sliding plate 12 is slidably engaged with the side end of the movable mold base 4, and the reset spring 10 is fixedly installed inside the movable mold base 4. The tension of the reset spring 10 plays the role of reset.
[0021] The mold cylinder 15 is adapted to the mold groove in the middle of the movable mold base 4, so that the injection molded part can be fully demolded and fall after the mold cylinder 15 is separated from the mold groove.
[0022] Working principle: During use, the injection material is transported to the injection tube 8 through the feed pipe 7. Then, the injection tube 8 is inserted into the moving mold base 4, allowing the material to be injected into the mold groove, thus enabling the lens barrel to be quickly injection molded. The electric push rod 3 is activated, causing the moving mold base 4 to move away from the fixed mold base 9. At this time, the moving mold base 4 and the fixed mold base 9 separate and open. The injection molded lens barrel separates and falls from the mold groove on the moving mold base 4. After the moving mold base 4 separates and opens from the fixed mold base 9, it continues to move. At this time, the extrusion sliding plate 12 and the extrusion frame 11 press and contact each other. The extrusion frame 11 pushes the extrusion sliding plate 12 to slide along the outside of the moving mold base 4. At this time, the return spring 10 is stretched. With the help of the auxiliary stabilizing spring 13 and the connecting plate 14, the extrusion sliding plate 12 separates and discharges the mold barrel 15 from the mold groove in the moving mold base 4, ensuring that the lens barrel formed inside the mold groove can be fully demolded and fall from the mold, so that the injection molding can be carried out continuously, stably and efficiently.
[0023] 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.
