[0014] Preferably, the slide rail is fixedly arranged on the side wall of the protruding rib.

[0015] The fixed connection mode of the slide rail and the protruding rib adopts a high-strength bolt or a welding process, so as to ensure that the slide rail has sufficient firmness during operation of the equipment. Such a setting can effectively reduce the loosening problem of the slide rail due to long-term use, and can also improve the bearing capacity of the overall structure to a certain extent.

[0016] Preferably, the top of the first bearing is separated from the top of the slide rail.

[0017] The first bearing and the top of the slide rail are kept apart, and such a design can effectively reduce the friction therebetween, thereby prolonging the service life of the slide rail and the bearing.

[0018] The second purpose of the utility model is to provide an injection molding machine.

[0019] The above purpose is achieved in the following manner.

[0020] The injection molding machine comprises an injection system, and the injection system comprises the stable structure of the moving table support and the shooting platform cover plate.

[0021] By adopting the technical scheme, the utility model discloses a precise bearing mechanism is arranged, so that reliable positioning and supporting effect can be obtained in the vertical direction and the horizontal direction of the shooting platform cover plate. This innovative design not only ensures that the shooting platform cover plate maintains a stable positional relationship during movement, but also effectively eliminates the common problems of deviation and shaking in traditional structures. When the shooting platform cover plate needs to move synchronously with the injection head plate, this bearing device can provide smooth guiding function, so that the shooting platform cover plate can accurately follow the movement trajectory of the injection head plate, thereby realizing high stability and accuracy of the entire system operation. This design significantly improves the operation reliability and service life of the equipment, and also provides a safer and more stable working environment for the operator.
