Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a mold with a rapid calibration mechanism. Background Technology

[0002] Machining molds are specialized tools used in industrial production for processes such as forming, stamping, and casting. Their core function is to efficiently and precisely process raw materials such as metal and plastic into parts or products of specific shapes through pre-set cavities or structures. Typical applications include injection molds (plastic products), stamping molds (metal sheet metal), and die-casting molds (metal castings), and they are widely used in the automotive, electronics, and home appliance industries.

[0003] Currently, traditional mold processing usually relies on manual adjustment or simple mechanical drive for mold closing and demolding, which has problems such as low positioning accuracy, poor demolding efficiency, and a lot of manual intervention. In particular, the calibration process of complex molds is time-consuming and prone to errors. Existing demolding mechanisms mostly use independent ejection devices, resulting in complex structures and insufficient synchronization.

[0004] Therefore, how to provide a machining mold with a rapid calibration mechanism is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a processing mold with a rapid calibration mechanism. By providing an opening and closing component, the mold can be rapidly calibrated, and after calibration, the mold can be opened to automatically demold the items inside, thereby solving the problems mentioned in the background art.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1 , Figure 2 , Figure 3 As shown, a processing mold with a rapid calibration mechanism includes a base box 1. Guide rods 4 are fixedly connected to the left and right sides of the top of the base box 1. A top plate 5 is fixedly connected between the top ends of the guide rods 4. An electric push rod 6 is fixedly connected to the middle of the top of the top of the top plate 5. A connecting block 7 is fixedly connected to the output end of the electric push rod 6. Second hinge rods 10 are hinged to the left and right sides of the outer wall of the connecting block 7. A first hinge rod 9 and a third hinge rod 11 are hinged to the end of the second hinge rod 10 away from the connecting block 7. A fixing block 8 is hinged to the end of the first hinge rod 9 away from the second hinge rod 10. The top end of the fixing block 8 is fixedly connected to the top plate 5. The third hinge rod 11 is hinged to the second hinge rod 9. A connector 12 is hinged to the bottom of the connecting rod 11. The bottom of the connector 12 is fixedly connected to the movable plate 13. A movable connecting block 3 is slidably connected to the outer wall of the guide rod 4. A movable plate 13 is fixedly connected to one side of the movable connecting block 3 near the middle of the bottom box 1. An upper mold 14 is fixedly connected to the bottom of the movable plate 13. Connecting rods 15 are fixedly connected to both the left and right sides of the bottom of the movable plate 13. A lower mold 2 is fixedly connected to the middle of the top of the bottom box 1. An ejector plate 20 is provided at the bottom of the inner wall of the lower mold 2. Two spring retraction rods 16 are fixedly connected to the bottom of the ejector plate 20. The bottom of the spring retraction rods 16 is fixedly connected to the connecting rod 15.

[0023] By sliding between the guide rod 4 and the movable connecting block 3, the movable plate 13 can be guided and assisted to move up and down. By activating the electric push rod 6, the connecting block 7 is moved downward. The downward movement of the connecting block 7 can cause the end of the second hinge rod 10 near the connecting block 7 to move downward. Through the hinge between the end of the second hinge rod 10 away from the connecting block 7 and the first hinge rod 9 and the third hinge rod 11, the second hinge rod 10 can cause the first hinge rod 9 to rotate away from the connecting block 7, and at the same time, it can cause the end of the third hinge rod 11 that is hinged to the second hinge rod 10 to rotate to the opposite side. Thus, the downward force can be transmitted to the movable plate 13 through the connecting member 12. The downward movement of the movable plate 13 can make the upper mold 14 and the lower mold 2 fit tightly together. Conversely, if it is necessary to demold the items inside the mold, the electric push rod 6 is activated to move the connecting block 7 upward, which can then cause the upper mold 14 to move upward through the movable plate 13. The movable plate 13 also drives the connecting rod 15 to move upward. The upward movement of the connecting rod 15 compresses the spring contraction rod 16 to contract. The contraction and upward movement of the spring contraction rod 16 can drive the ejector plate 20 to move upward. The ejector plate 20 extrudes the items inside the mold, which can achieve rapid demolding of the items.

[0024] refer to Figure 1 , Figure 2 , Figure 3 As shown, a storage box 17 is provided on the left side of the bottom of the bottom box 1, and a material pump 19 is provided in the middle of the inner wall of the bottom box 1. A material pump 18 is fixedly connected to the input end of the material pump 19. The end of the material pump 18 away from the material pump 19 is fixedly connected to the storage box 17. A discharge pipe 21 is fixedly connected to the output end of the material pump 19. The top end of the discharge pipe 21 is fixedly connected to the lower mold 2.

[0025] By activating the material pump 19, the material is extracted from the storage box 17 through the material extraction pipe 18, which facilitates the processing and shaping of the item through the mold. Then, the material is discharged into the lower mold 2 through the discharge pipe 21 at the output end of the material pump 19.

[0026] Working principle:

[0027] By sliding between the guide rod 4 and the movable connecting block 3, the movable plate 13 can be guided and assisted to move up and down. Activating the electric push rod 6 moves the connecting block 7 downwards. This downward movement of the connecting block 7 causes the end of the second hinge rod 10 near the connecting block 7 to move downwards. Through the hinge between the end of the second hinge rod 10 away from the connecting block 7 and the first hinge rod 9 and the third hinge rod 11, the second hinge rod 10 can cause the first hinge rod 9 to rotate away from the connecting block 7, while simultaneously causing the end of the third hinge rod 11 hinged to the second hinge rod 10 to rotate to the opposite side. The rotation of the upper mold 14 allows downward force to be transmitted to the movable plate 13 via the connecting piece 12. The downward movement of the movable plate 13 brings the upper mold 14 and lower mold 2 into close contact. Then, the material pump 19 is activated to extract material from the storage box 17 through the extraction pipe 18, facilitating the molding of the item through the mold. The material is then discharged into the lower mold 2 through the discharge pipe 21 at the output end of the material pump 19. Conversely, if demolding is required, the electric push rod 6 is activated, causing the connecting block 7 to move upward. This, in turn, causes the upper mold 14 to move upward via the movable plate 13. Simultaneously, the movable plate 13 also causes the connecting rod 15 to move upward. The upward movement of the connecting rod 15 compresses the spring contraction rod 16, causing it to contract. The contraction and upward movement of the spring contraction rod 16 then causes the ejector plate 20 to move upward, extruding the item from the mold. This allows for rapid demolding of the item while the mold is being opened.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
