Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically to a plastic mold with a double limiting structure. Background Technology

[0002] Plastic molds are specialized tools used for the mass production of plastic parts. By injecting molten plastic into the mold cavity and then cooling and solidifying it, a plastic product with the same shape as the mold cavity is obtained. In order to help the plastic mold move stably and limit its movement during the preparation of plastic parts, a plastic mold with a double limiting structure is needed.

[0003] In traditional plastic molds, the left and right molds open and close horizontally. However, traditional devices cannot guarantee the stable movement of plastic molds of different shapes and sizes, which can easily lead to problems in the stable production of plastic parts after the molds are joined. Furthermore, traditional devices cannot stably limit the movement path of the molds, thus affecting the stable use of the device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a plastic mold with a double limiting structure to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a plastic mold with a double limiting structure, including a fixed frame, a side plate slidably connected to the inner wall of the fixed frame, a slide plate fixedly mounted at the bottom of the side plate, an outer cylinder fixedly mounted on the side of the slide plate, a slide tube slidably sleeved on the inner wall of the outer cylinder, an adjusting plate fixedly mounted on the side of the slide tube, a slide frame fixedly mounted on the side of the adjusting plate, a clamping frame slidably connected to the inner wall of the slide frame, a gear rotatably connected to the side of the clamping frame, a round rod fixedly mounted on the side of the gear, and the outer edge of the round rod rotatably sleeved with the inner wall of the clamping frame, a rotating plate fixedly mounted on the outer edge of the round rod, a clamping plate fixedly mounted on the side of the rotating plate, and a guide rod fixedly mounted on the inner wall of the fixed frame, and the outer edge of the guide rod slidably sleeved with the inner wall of the side plate.

[0006] As a preferred embodiment of this utility model, a positioning frame is fixedly mounted on the side of the clamping frame, a spring is fixedly connected to the side of the inner wall of the positioning frame, and a toothed plate is fixedly connected to the end of the spring away from the inner wall of the positioning frame, and the convex teeth of the toothed plate mesh with the convex teeth of the gear.

[0007] As a preferred technical solution of this utility model, the side of the positioning frame is provided with a limiting groove, the side of the toothed plate is fixedly equipped with a circular plate, the side of the circular plate is rotatably connected to the limiting plate, and the shape and size of the outer edge of the limiting plate are adapted to the shape and size of the inner wall of the limiting groove, and the side of the limiting plate is fixedly equipped with an adjusting rod.

[0008] As a preferred embodiment of this utility model, an inner cylinder is fixedly sleeved on the inner wall of the outer cylinder, the outer edge of the inner cylinder is slidably sleeved with the inner wall of the slide cylinder, a slide rod is slidably sleeved on the inner wall of the inner cylinder, and the side of the slide rod is fixedly assembled with the side of the adjusting plate, a coil is fixedly sleeved on the inner wall of the outer cylinder, a magnet ring is fixedly assembled on the side of the slide cylinder, and the outer edge of the magnet ring is slidably sleeved with the inner wall of the coil.

[0009] As a preferred technical solution of this utility model, a self-locking motor is fixedly mounted on the side of the fixing frame, and a positive and negative threaded rod is fixedly sleeved on the output shaft of the self-locking motor. The outer edge of the positive and negative threaded rod is threadedly connected to the inner wall of the slide plate. There are two slide plates, and the inner walls of the two slide plates are respectively threadedly connected to the outer edges of the positive and negative threaded rod near both ends.

[0010] As a preferred technical solution of this utility model, a self-locking motor II is fixedly mounted on the side of the sliding frame, and a positive and negative threaded rod II is fixedly sleeved on the output shaft of the self-locking motor II. The outer edge of the positive and negative threaded rod II is threadedly connected to the inner wall of the clamping frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This plastic mold with a double limiting structure uses the cooperation of the sliding frame and the clamping plate to move the adjusting rod. The adjusting rod drives the outer edge of the limiting plate through the inner wall of the limiting groove to the side of the positioning frame. Then, the adjusting rod is rotated so that when the side of the limiting plate overlaps the side of the positioning frame, the convex teeth of the toothed plate and the convex teeth of the gear separate, placing the plastic mold on the side of the sliding frame. Then, the self-locking motor II drives the positive and negative threaded rod II to rotate, thereby driving the clamping plate to rotate. The clamping plate is adjusted to fit the outer surface of the plastic mold, thus ensuring the stable limiting of the plastic mold.

[0012] 2. This plastic mold with a double limiting structure uses a sliding rod and a sliding cylinder in combination. When the self-locking motor drives the positive and negative threaded rods to rotate, the positive and negative threaded rods drive the sliding plate to slide in the inner wall of the fixed frame. This assists the outer edge of the sliding rod to slide in the inner wall of the inner cylinder, the outer edge of the sliding cylinder to slide in the inner wall of the outer cylinder, and the inner wall of the sliding cylinder to slide in the outer edge of the inner cylinder. In turn, the sliding cylinder drives the magnetic ring to slide in the inner wall of the coil, thereby assisting in shock absorption when the plastic mold moves, preventing the plastic mold from shifting position, and further ensuring the stability of the plastic mold's movement.
