Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a mold that is easy to clean. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is a tool that makes the blank into a part with a specific shape and size under the action of external force. In the process of mold manufacturing and use, injection molding is usually processed by a combination of upper and lower molds. After injection molding, the model inside the lower mold is usually not easy to demold. Due to the frequent need to handle various materials, the residual materials in the mold cavity are difficult to clean and are prone to residues such as oil, dust and other impurities, which will affect the subsequent mold processing quality.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] The present application provides a mold that is easy to clean using the following technical solution:

[0006] A mold that is easy to clean comprises a base, a fixed mold is fixedly installed on one side of the top of the base, an injection tube is connected to the outer wall of the fixed mold, a mold cavity is opened at the top of the fixed mold, a slide rail is opened in the middle of the top of the base, a screw rod assembly is installed in the slide rail, a movable mold is arranged on the screw rod assembly, and a convex mold plate adapted to the mold cavity is arranged at the top of the movable mold.

[0007] Preferably, a positioning hole is opened in the middle of the inner wall of the top end of the fixed mold, and a positioning shaft adapted to the positioning hole is fixed in the middle of the inner wall of the top end of the movable mold.

[0008] Preferably, a servo motor is installed on the outer wall of the movable mold, a working groove is opened inside the movable mold, and a gear 1 is provided at the bottom of the working groove.

[0009] Preferably, the output end of the servo motor passes through the inner wall of the movable mold and is transmitted to a gear, and a movable groove is provided inside the top end of the working groove.

[0010] Preferably, a second gear is provided at the top of the working groove, a connecting screw is fixed inside the second gear, and the connecting screw is threadedly connected to the inner wall of the working groove.

[0011] Preferably, a contraction cavity adapted to the male mold plate is provided on the top surface of the movable mold, and one end of the connecting screw extends into the contraction cavity and is movably connected to the outer wall of the male mold plate.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The present application arranges a combination of a fixed mold, a movable mold and a male mold plate, and drives the movable mold to move close to the fixed mold through a screw rod assembly, so that the male mold plate can enter the mold cavity for mold closing, thereby allowing subsequent injection molding processing. After injection molding, the male mold plate can be ejected from the outside as it shrinks and resets in the shrinkage cavity, achieving rapid demolding and avoiding the model from remaining in the mold cavity that is difficult to clean. The overall structure is simple, demolding is convenient, and residues in the mold cavity are reduced, making subsequent cleaning convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a mold that is easy to clean. Figure 1, including a base 1, a fixed mold 2 is fixedly installed on one side of the top of the base 1, an injection tube 9 is connected to the outer wall of the fixed mold 2, a mold cavity 3 is opened at the top of the fixed mold 2, and an injection molding device is connected through the injection tube 9 to facilitate the transportation of materials to the inside of the mold cavity 3, a slide rail 7 is opened in the middle of the top of the base 1, a screw assembly 8 is installed in the slide rail 7, the screw assembly 8 includes a motor, a screw and a slider, a movable mold 5 is fixedly connected to the top of the slider, and a convex mold plate 12 adapted to the mold cavity 3 is provided at the top of the movable mold 5. When the screw drives the slider to approach the fixed mold 2, the convex mold plate 12 fits with the mold cavity 3 to perform mold forming.

[0020] like Figure 2 As shown, a positioning hole 4 is opened in the middle of the inner wall at the top of the fixed mold 2, and a positioning shaft 11 adapted to the positioning hole 4 is fixed in the middle of the inner wall at the top of the movable mold 5. When the movable mold 5 slides close to the fixed mold 2, the positioning shaft 11 enters the positioning hole 4 for positioning.

[0021] Combination Figure 3 As shown, a servo motor 6 is installed on the outer wall of the movable mold 5, a working groove 10 is opened inside the movable mold 5, a gear 13 is arranged at the bottom of the working groove 10, the output end of the servo motor 6 penetrates the inner wall of the movable mold 5 and is transmitted with the gear 13, and a movable groove 14 is opened inside the top of the working groove 10, and the movable groove 14 is a horizontal slide groove;

[0022] A second gear 15 is provided at the top of the working groove 10, and a connecting screw 16 is fixed inside the second gear 15. One end of the connecting screw 16 extends to the inside of the movable groove 14, and the connecting screw 16 is threadedly connected to the inner wall of the working groove 10. When the first gear 13 rotates, it will mesh with the second gear 15, and then the second gear 15 will drive the connecting screw 16 to move to one side in the movable groove 14 as the gear 13 meshes.

[0023] A contraction cavity 17 adapted to the male mold plate 12 is opened on the top surface of the movable mold 5, and one end of the connecting screw 16 extends into the contraction cavity 17 and is movably connected to the outer wall of the male mold plate 12, so that the male mold plate 12 can be pushed to slide out or reset in the contraction cavity 17.

[0024] The implementation principle of a mold that is easy to clean in the embodiment of the present application is as follows: when in use, the screw assembly 8 is started to work, and the movable mold 5 is driven by the slider to move to one side on the slide rail 7 to approach the fixed mold 2, and the positioning shaft 11 is pushed to slide into the positioning hole 4 to position the fixed mold 2 and the movable mold 5 to avoid offset, and then the servo motor 6 is started to drive the gear 13 inside the working groove 10 to rotate, and then the gear 13 moves to mesh with the gear 2 15, and the gear 2 15 rotates to drive the connecting screw 16 to rotate on the inner wall of the movable mold 5 away from the movable mold 5. The movable groove 14 can push the convex plate 12 inside the shrinkage cavity 17 to move outward and enter the mold cavity 3 for mold closing, and then connect the external injection molding equipment through the injection molding tube 9, so as to facilitate the injection molding of the raw materials into the mold cavity 3 for processing and molding. After the model is processed and formed, the movable mold 5 is reset away from the fixed mold 2, and the convex plate 12 is reset at the same time.
