Description

Technical Field

[0001] This utility model belongs to the field of molds, and in particular relates to a rocker plate resetting structure for plastic molds. Background Technology

[0002] Molds play a vital role in plastic manufacturing, improving the quality and speed of plastic production. During the production process of plastic molds, the reset mechanism is an important component to ensure the normal operation of the mold. Existing rocker reset structures often use springs for reset, but prolonged use of springs can lead to insufficient reset capacity. Utility Model Content

[0003] The purpose of this utility model is to provide a plastic mold rocker reset structure to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A plastic mold rocker reset structure includes a lower mold, a mold groove, a mounting groove, a rocker, and a motor. The lower mold has a mold groove, which is integrated with the mold groove of the upper mold. The lower mold has at least one mounting groove, which connects the upper mold and the lower mold. A rocker is installed at the bottom of the mold groove. There are at least two rockers, which are symmetrically arranged along the diagonal of the mold groove. A motor is located on the outside of the lower mold.

[0006] Preferably, a groove is provided at the bottom of the mold groove, a rocker plate is installed in the groove, one end of the rocker plate is connected to the inner wall of the groove via a shaft, the other end of the rocker plate is not fixed, and a guide groove is provided on the side wall of the groove.

[0007] Preferably, the rocker is a wedge-shaped block design, with a movable block below the rocker and integrally formed inserts on both sides of the movable block. The inserts are slidably connected to the guide groove. The movable block is wedge-shaped and has a threaded screw connected to it. The screw passes through the lower mold and connects to the motor.

[0008] Preferably, the groove is provided with a support block installed by screws. The support block is located below the end of the rocker that is not fixed. A magnet is embedded above the support block. The bottom of the rocker is provided with an iron plate installed by screws. When the rocker contacts the support block, the rocker is flush with the mold groove.

[0009] Compared with the prior art, the present invention has the following advantages: The present invention is reasonably designed; the motor drives the lead screw to rotate, and the moving plate on the lead screw can move forward and backward with the lead screw. When the highest point of the moving plate contacts the rocker, the rocker can be raised. When the rocker does not need to be raised, the lead screw is used to move the highest point of the moving plate away from the bottom of the rocker, and the rocker contacts the support block under the action of the magnet.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1-3 As shown, a plastic mold rocker reset structure includes a lower mold 1, a mold groove 2, a mounting groove 3, a rocker 4, and a motor 5. The lower mold 1 has a mold groove 2, which forms an integral part with the mold groove of the upper mold. The lower mold 1 has at least one mounting groove 3, which connects the upper mold and the lower mold 1. A rocker 4 is installed at the bottom of the mold groove 2, and at least two rockers 4 are provided, symmetrically arranged along the diagonal of the mold groove 2. A motor 5 is provided on the outside of the lower mold 1, and the motor has forward and reverse rotation functions. A groove 6 is provided at the bottom of the mold groove 2, and the rocker 4 is installed in the groove 6. One end of the rocker 4 is connected to the inner wall of the groove 6 via an shaft. The rocker arm 4 is not fixed at the other end. A guide groove 7 is provided on the side wall of the groove 6. The rocker arm 4 is designed as a wedge. A movable block 8 is provided below the rocker arm 4. An integrally formed insert block 11 is provided on both sides of the movable block 8. The insert block 11 is slidably connected to the guide groove 7. The movable block 8 is designed as a wedge. A threaded screw 9 is provided on the movable block 8. The screw 9 passes through the lower mold 1 and is connected to the motor 5. A screw-installed support block 10 is provided in the groove 6. The support block 10 is located below the unfixed end of the rocker arm 4. A magnet 12 is embedded above the support block 10. A screw-installed iron plate is provided at the bottom of the rocker arm 4. When the rocker arm 4 contacts the support block 10, the rocker arm 4 is flush with the mold groove 2.

[0015] The working principle of this utility model is as follows: When the mold needs to be installed, the upper mold and the lower mold are connected together by the installation groove. During plastic manufacturing, the motor drives the lead screw to rotate, so that the high point of the moving block on the lead screw is away from the low point of the rocker. The iron plate on the rocker is attracted by the magnet and contacts the support block. After the rocker contacts the support block, the mold groove is horizontal. When it is necessary to remove the plastic, the lead screw on the motor drives the moving block to move, so that the high point of the moving block contacts the low point of the rocker, thereby making the rocker tilt upward and lifting the plastic for easy removal.

[0016] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
