Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically to a mold rotating mechanism. Background Art

[0002] A mold is various molds and tools used in industrial production to obtain required products by methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. In short, a mold is a tool for making formed articles. Such a tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the outer shape of an article by changing the physical state of the formed material. When using a mold for injection molding, there is a process called two-color injection molding, which means injecting two different materials into the same set of molds, so that the injected parts are formed by two materials. This process can be completed by two types of molds. One is a mold with two or more cavities and the whole mold can rotate, and the other is a rotating mold with two or more cavities that can rotate and is equipped inside the mold. Both molds have two or more injection ports, and different injection ports inject different materials. When in use, first inject the first material into one cavity, then rotate the mold or the rotating mold, rotate the cavity injected with the first material to the position of the injection port for injecting the second material, and then inject the second material to complete two-color injection molding.

[0003] Currently, when using a mold equipped with a rotating mold, since the rotating mold needs to be engaged inside the mold during injection molding, to complete the rotation of the rotating mold, it is necessary to first push the rotating mold out of the mold, then rotate it, and finally re-engage the rotating mold into the mold. When the staff installs and adjusts the mold, they need to consider the coordination between the injection molding machine and the above three strokes, and the process is relatively cumbersome. Therefore, there is an urgent need to design a mold rotating mechanism to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a mold rotating mechanism to solve the problem that the process of installing and debugging a mold equipped with a rotating mold is relatively cumbersome as described in the above background art.

[0005] The utility model provides the following technical solution: A mold rotating mechanism includes an outer mold, and also includes a rotating mold assembly, a hydraulic power assembly, and an electric motor power assembly. The rotating mold assembly is arranged inside the outer mold. The hydraulic power assembly is arranged at the rear side of the outer mold, and the hydraulic power assembly is connected to the rotating mold assembly. The hydraulic power assembly can drive the rotating mold assembly to slide quantitatively. The electric motor power assembly is arranged inside the outer mold, and the electric motor power assembly is also connected to the rotating mold assembly. The electric motor power assembly can drive the rotating mold assembly to rotate quantitatively.

[0006] Further, the rotary die assembly includes a rotary die body and a movable rod. A die groove is formed on the front side of the outer die. The rotary die body is slidably installed in the die groove, and the movable rod is fixedly installed on the rear side of the rotary die body.

[0007] Further, the hydraulic power assembly includes a hydraulic cylinder body and a connecting block. The hydraulic cylinder body is fixedly installed on the rear side of the outer die, and the connecting block is fixedly installed on the piston end of the hydraulic cylinder body.

[0008] Further, a connecting groove is formed on one side of the movable rod close to the hydraulic cylinder body, and the connecting block is rotatably installed in the connecting groove.

[0009] Further, the motor power assembly includes a collar, a bevel gear ring, a bevel gear, a rotating rod, and a motor body. A circular groove is formed on the inner wall of one side of the die groove. The collar is rotatably installed in the circular groove. The movable rod is movably inserted into the collar. The bevel gear ring is fixedly installed on the outer wall of the collar. A square groove is formed on the rear side of the outer die, and the square groove communicates with the circular groove. The bevel gear is rotatably installed on the inner wall of one end of the square groove, and the bevel gear meshes with the bevel gear ring. The rotating rod is rotatably installed in the outer die. The motor body is fixedly installed at one end of the outer die. Both ends of the rotating rod are fixedly connected to the bevel gear and the output shaft of the motor body respectively.

[0010] Further, the rotary die assembly further includes two slide bars. Two slide grooves are formed on the inner wall of the collar. The two slide bars are respectively slidably installed in the two slide grooves.

[0011] Further, four positioning columns are fixedly installed in the die groove. Four positioning holes are formed between the two sides of the rotary die body. The positioning holes are adapted to the positioning columns.

[0012] The technical effects and advantages of the present utility model:

[0013] In the use of this utility model, when starting the hydraulic cylinder body, the movable rod is pushed to slide forward on the outer mold, and then the rotary mold body is pushed to slide out of the mold groove. It should be noted that the extension distance of the piston end of the hydraulic cylinder body is fixed. When the rotary mold body completely disengages from the mold groove, the motor body is started to drive the rotating rod and bevel gear to rotate, which can drive the bevel gear ring and collar to rotate, and then drive the movable rod to rotate through the two sliding strips, thus driving the rotary mold body to rotate. Through the arranged connecting block and connecting groove, the movable rod can rotate while remaining connected to the hydraulic cylinder body. It should be noted that the rotation amount of the bevel gear driven by the motor body is fixed, and one rotation amount can just make the rotary mold body rotate 180 degrees. When the rotary mold body finishes rotating, the hydraulic cylinder body is started again to pull back the movable rod and drive the rotary mold body back into the mold groove, and the rotation of the rotary mold body can be completed. Through the arranged hydraulic power assembly and motor power assembly, the rotation switching of the rotary mold assembly can be completed on the outer mold itself without relying on external power, and there is no need to consider the coordination with the injection molding machine too much during installation and debugging, which can relatively simplify the installation and adjustment process.
