AI Technical Summary
In the existing lifting mechanism of injection molding machines, the top of the guide rod is not fixed, resulting in insufficient installation strength. The guide rod is prone to shaking when the injection molding machine is raised or lowered, and the stability is low.
A reinforcing member is installed at the top of the platform and fixedly connected to the guide rod. The support plate is driven to slide through the adjusting member and fixed to the guide rod with the locking member, thereby improving the installation strength of the guide rod.
This effectively prevents the guide rod from wobbling and improves the stability of the injection molding machine's lifting and lowering.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting mechanism technology, specifically to a lifting mechanism for an injection molding machine. Background Technology
[0002] An injection molding machine is a specialized piece of equipment used to manufacture shoe soles. It heats thermoplastic materials (such as PVC, TPR, EVA, etc.) to a molten state and injects them under high pressure into a pre-defined mold. After cooling and solidification, the desired shoe sole shape is formed. This production method offers advantages such as high efficiency, low cost, and the ability to achieve complex designs.
[0003] Because different molds have different heights, a lifting mechanism is usually used to adjust the height of the injection molding machine to ensure that the molten material can be injected into the mold. The existing lifting mechanism sets multiple guide rods on the platform, and the support plate is slidably connected to the guide rods. The injection molding machine is installed on the support plate, and the adjusting component is set in the platform and connected to the support plate. The adjusting component drives the support plate to slide along the axis of the guide rods. Because the top of the guide rod is not fixed, the installation strength is insufficient, and the injection molding machine is relatively heavy, the guide rod is prone to shaking when the adjusting component drives the support plate to slide, which makes the stability of the injection molding machine low when lifting.
