Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary mold installation of an injection molding machine, in particular to a mold lifting device used on an injection molding machine. Background Art

[0002] At present, molds are used for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods to obtain various required products. The molds or tools are the core of modern manufacturing industry. Because they involve all aspects of production and manufacturing, they are widely used in modern factories. Large molds have the characteristics of large size and heavy mass due to their stability requirements, so the position of the mold is difficult to move easily.

[0003] Among them, when the mold needs to be installed or moved on the injection molding machine, this work is often difficult and requires the use of multiple people and corresponding moving tools, which is time-consuming and labor-intensive.

[0004] The conventional method of lifting the mold uses a slide rail design, which can reduce the friction between the mold and the mold. However, the mold can only be moved in or out of the side of the injection molding machine along the fixed slide rail direction, and it is not easy to move the mold to the middle position. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a mold lifting device for an injection molding machine, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mold lifting device for an injection molding machine, comprising a movable frame, both sides of which are provided with limit slide grooves, two groups of limit slide grooves are slidably installed with limit slide plates, and a mold lifting mechanism is installed on the limit slide plate;

[0007] The mold lifting mechanism includes support frames fixedly installed on both sides of the top of the limiting slide plate, lifting plates fixedly installed on the top of the two groups of support frames, multiple groups of equally spaced guide rollers rotatably installed inside the lifting plates, telescopic rods rotatably installed on both sides of the guide rollers on one side, clamping rollers rotatably installed on the other sides of the two groups of telescopic rods, a positioning rod between the clamping rollers and the guide rollers, and a guide cloth fixedly installed on one side of the positioning rod.

[0008] As an optional solution of the technical solution of the present application, the outer wall of each group of telescopic rods is sleeved with a spring, and the two sides of each group of springs are detachably mounted on the telescopic rods and the outer wall of the guide roller, respectively, to support the clamping roller.

[0009] As an optional solution to the technical solution of the present application, the guide cloth is formed by cross-weaving multiple groups of fishing lines, and convex plates are fixedly installed on the bottom of both sides of the lifting plate to support the concave frame.

[0010] As an optional solution of the technical solution of the present application, a concave frame is arranged on one side of the lifting plate, and first screw holes are opened in the middle of both sides of the concave frame to position the concave frame.

[0011] As an optional solution of the technical solution of the present application, a limiting frame is fixedly installed on one side of the limiting slide, and a second screw hole is opened in the middle of one side of the limiting frame. Each group of the second screw holes and the first screw holes are threadedly connected with bolts, which can position the limiting slide.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The technical solution of the present application unfolds the guide cloth in the mold lifting mechanism from the outside of the guide roller, lays it flat on the designated workbench, loosens the bolts on the concave frame, separates the concave frame from the lifting plate, pushes the mold on the lifting plate, and allows the mold to easily slide to one side of the workbench along multiple sets of guide rollers. In combination with the guide cloth, the operator can move the mold to the middle of the workbench with less effort, thereby avoiding the need for multiple operators to lift the mold to the workbench in a time-consuming and laborious manner.

[0014] 2. The technical solution of the present application is provided with a second screw hole in the middle part of one side of the limit frame, and each group of the second screw holes is threadedly connected with a bolt. When the movable frame is placed on the transport lifting plate to transport the mold, it is necessary not only to screw in the bolts in the first screw holes to position the mold on the lifting plate, but also to screw in the bolts in the second screw holes to position the limit slide block in the limit slide groove to ensure the stability and firmness of the mold during transportation.
