Description

Technical Field

[0001] This utility model relates to the field of template device technology, specifically a shell mold combination template device that is easy to disassemble and maintain. Background Technology

[0002] In the field of mold manufacturing and processing, modular mold assembly devices with easily disassembled and maintained shell molds are key tooling for ensuring production continuity. This device, through an innovative mechanical connection structure, enables rapid assembly and disassembly of mold components and is widely used in molding processes such as injection molding and die casting. Its core function is to simplify mold maintenance procedures, reduce equipment downtime, and provide technical support for enterprises to improve production efficiency and reduce operating costs.

[0003] Traditional shell mold template devices suffer from significant operational drawbacks. Previous mold installation and disassembly relied heavily on external tools such as wrenches and screwdrivers, involving tightening or loosening numerous bolts for fixation—a cumbersome and time-consuming process. When molds malfunction or require regular maintenance, this method not only consumes substantial manpower but also leads to prolonged equipment downtime, severely impacting production schedules. Furthermore, frequent tool disassembly can cause bolt stripping and thread wear, increasing the risk of mold damage and further raising maintenance costs. Simultaneously, the complex disassembly process demands a high level of operator skill; novice operators are prone to improper installation, causing mold positioning deviations and affecting product molding quality. These problems make traditional mold devices unable to meet the urgent needs of modern manufacturing for efficient and convenient maintenance. Therefore, we propose a modular template device for shell molds that facilitates disassembly and maintenance. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that the installation and disassembly of existing template devices mostly rely on external tools such as wrenches and screwdrivers. Fixing is accomplished by tightening or loosening a large number of bolts.

[0007] In some embodiments, the upper end of the lower mold assembly located at the middle of the upper end of the lower mold frame is correspondingly connected to the lower end of the upper mold located at the lower end of the upper mold frame.

[0008] In some embodiments, the connecting component has the same structure as the connecting mechanism, and the connecting component is limitedly connected to the lower mold component.

[0009] In some embodiments, two connecting components are respectively provided on the outer walls of both sides of the lower mold assembly.

[0010] In some embodiments, the first threaded groove on the fixing block is correspondingly connected to the second threaded groove on the connecting plate, and the connecting bolts are threadedly connected to the first threaded groove and the second threaded groove.

[0011] In some embodiments, the knob block at one end of the connecting bolt is rectangular and is connected to the limiting groove on the limiting block.

[0012] In some embodiments, two connecting mechanisms are provided on each side of the upper mold.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. In use, this utility model utilizes a combination of a knob block, connecting bolts, and limiting grooves to achieve rapid fixing and disassembly of the upper mold.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a modular template device for easy disassembly and maintenance of a shell mold, including an upper mold frame 1, a connecting mechanism 2 fixedly connected to the lower outer wall of the upper mold frame 1, an upper mold 3 movably connected to the lower outer wall of the upper mold frame 1, two connecting mechanisms 2 respectively provided on both sides of the upper mold 3, and two connecting plates 4 fixedly connected to the outer walls of both sides of the upper mold 3, with a second threaded groove 5 opened on the connecting plate 4. The connecting mechanism 2 includes a fixing block 21 fixed to the lower outer wall of the upper mold frame 1, a first threaded groove 22 opened on one side of the fixing block 21, and a fixed connection on one side of the fixing block 21. A connecting shaft 23 is connected, and a limiting block 24 is movably connected to the outer wall of the connecting shaft 23. A limiting groove 25 is opened on the limiting block 24. A connecting bolt 26 is threadedly connected to one side of the inner wall of the first threaded groove 22. The first threaded groove 22 opened on the fixing block 21 is correspondingly connected to the second threaded groove 5 opened on the connecting plate 4, and the connecting bolt 26 is threadedly connected to both the first threaded groove 22 and the second threaded groove 5. A knob block 27 is fixedly connected to one end of the connecting bolt 26. The knob block 27 provided at one end of the connecting bolt 26 is rectangular and is correspondingly connected to the limiting groove 25 opened on the limiting block 24.

[0025] In this embodiment, an upper mold frame 1 is designed, and an upper mold 3 is provided at the lower middle part of the upper mold frame 1. A connecting plate 4 is fixedly connected to the outer walls of both sides of the upper mold 3, and a second threaded groove 5 is provided on the connecting plate 4. Two connecting mechanisms 2 are respectively provided on both sides of the lower end of the upper mold frame 1. Four connecting plates 4 are respectively provided on the side walls of the upper mold 3 and are correspondingly connected to the connecting plates 4 provided on the side walls of the upper mold 3. The connecting mechanism 2 specifically includes a fixing block 21, and a first threaded groove 22 is provided on the fixing block 21. The first threaded groove 22 can be correspondingly connected to the second threaded groove 5 provided on the connecting plate 4. A limiting block 24 is movably connected to one side of the fixing block 21 through a connecting shaft 23. A limiting groove 25 is provided on the limiting block 24. When the limiting groove 25 is rotated around the connecting shaft 23 and connected to the fixing block 21, the limiting groove 25 can be correspondingly connected to the first threaded groove 22 and the second threaded groove 5. Thus, a connecting bolt 26 is provided. The connecting bolt 26 can extend to the other side of the limiting groove 25 and be threadedly connected to the first threaded groove 22 and the second threaded groove 5. A knob block 27 is provided at one end of the connecting bolt 26. The knob block 27 is rectangular with a relatively convex middle part, which can be directly pinched and rotated by a person. Therefore, when the upper mold 3 can be slid to the side of the connecting plate 4 to the fixed block 21, the knob block 27 can be pinched and the connecting bolt 26 can be drilled, so that the connecting bolt 26 is threadedly connected to the first threaded groove 22 and the second threaded groove 5. At this time, the knob block 27 is turned horizontally, and the knob block 27 and the limiting groove 25 are cross-shaped, which can ensure the fixing effect of the knob block 27, so that the upper mold 3 can be fixed to the lower side of the upper mold frame 1 by the knob block 27. Conversely, it can be disassembled. This method avoids the need to use external tools to install and disassemble it, which makes it possible to quickly disassemble and maintain the upper mold 3 and meet the needs of different styles and shapes in a timely manner.

[0026] Example 2: Please refer to Figure 1-3 The lower end of the upper mold frame 1 is fixedly connected to a telescopic rod 6, and the lower end of the telescopic rod 6 is movably connected to a lower mold frame 7. Four connecting components 8 are fixedly connected to the outer wall of one side of the upper end of the lower mold frame 7. The middle of the upper outer wall of the lower mold frame 7 is movably connected to a lower mold assembly 9. The upper end of the lower mold assembly 9 located in the middle of the upper end of the lower mold frame 7 is correspondingly connected to the lower end of the upper mold 3 located at the lower end of the upper mold frame 1. The connecting components 8 have the same structure as the connecting mechanism 2, and the connecting components 8 are limitedly connected to the lower mold assembly 9. Two connecting components 8 are respectively located on the outer walls of both sides of the lower mold assembly 9. The lower outer wall of the lower mold frame 7 is fixedly connected to a support foot 10.

[0027] In this embodiment, a lower mold frame 7 is connected to the lower end of the upper mold frame 1 via a telescopic rod 6. The telescopic rod 6 is telescopic and can drive the upper mold frame 1 and the upper mold 3 connected at the lower end to move longitudinally. A lower mold assembly 9 is provided in the middle of the lower mold frame 7. Two connecting components 8 are provided on both sides of the lower mold assembly 9. The upper end of the lower mold assembly 9 is connected to the lower end of the upper mold 3. Therefore, when the upper mold 3 moves downward, it can connect with the lower mold assembly 9 to complete the mold making operation. The connecting components 8 have the same structure as the connecting mechanism 2, and can also quickly fix and disassemble the lower mold assembly 9. However, the side wall connecting the connecting components 8 and the lower mold assembly 9 is different from the side wall connecting the connecting mechanism 2 and the upper mold 3. This avoids the connecting mechanism 2 and the connecting components 8 from contacting each other when the upper mold 3 and the lower mold assembly 9 are connected, which would prevent the upper mold 3 and the lower mold assembly 9 from working together completely, thus resulting in the production of defective products. A support foot 10 is provided at the bottom of the upper mold frame 1, which can support the device.

[0028] like Figure 1-4 As shown, this device, through its precise mechanical design and pneumatic control system, is mainly used for the rapid installation, disassembly, and longitudinal movement of molds, ensuring efficient and flexible completion of mold production tasks.

[0029] The core component of the device is the upper mold frame 1, which supports the upper mold 3 and ensures its stability and precision during the production process. Connecting plates 4 are connected to both sides of the upper mold 3, and second threaded grooves 5 are formed on the connecting plates 4. The upper mold 3 is tightly integrated with the connecting mechanism 2 through these connecting plates 4, forming a fixed structure.

[0030] Two connecting mechanisms 2 are respectively provided on both sides of the lower end of the upper mold frame 1. The connecting mechanism 2 is fixed to the upper mold frame 1 by a fixing block 21, and the fixing block 21 has a first threaded groove 22, which can precisely match the second threaded groove 5 on the connecting plate 4. The design of the connecting mechanism 2 allows the upper mold 3 to be quickly disassembled and installed through simple operation. Each connecting mechanism 2 also includes a limiting block 24 movably connected by a connecting shaft 23, and the limiting block 24 has a limiting groove 25. When the limiting groove 25 rotates through the connecting shaft 23, it can mate with the first threaded groove 22 and the second threaded groove 5, ensuring a stable fixing force.

[0031] For easy adjustment and fixation, connecting bolts 26 are used to securely connect the connecting mechanism 2 and the upper mold 3 together. One end of the connecting bolt 26 is equipped with a knob block 27, which has a rectangular design and a raised portion that allows the operator to easily rotate and lock it. Once the knob block 27 is in place, the connecting bolt 26 is securely threaded into the first threaded groove 22 and the second threaded groove 5, ensuring the upper mold 3 is fixed in the upper mold holder 1. In this way, the operator can easily disassemble or install the upper mold 3 without external tools, making the process quick and convenient.

[0032] The device is also equipped with a telescopic rod 6, which connects to the lower mold frame 7 to enable longitudinal movement of the upper mold frame 1. The telescopic nature of the telescopic rod 6 allows the upper mold frame 1 and the upper mold 3 to move flexibly up and down in the vertical direction to adapt to different production needs. The lower mold assembly 9 is installed in the middle of the lower mold frame 7, which fits tightly with the upper mold 3 to ensure the accuracy of mold making.

[0033] The lower mold assembly 9 is also equipped with two connecting assemblies 8 on both sides. Their structure is the same as that of the connecting mechanism 2, thus enabling quick installation and disassembly. The side wall of the connecting assembly 8 that connects to the lower mold assembly 9 is slightly different from the side wall of the upper mold 3 connected by the connecting mechanism 2. This design effectively avoids interference problems when the upper mold 3 and the lower mold assembly 9 are connected, ensuring precise alignment of the mold assemblies and avoiding production defects caused by loose connections.

[0034] The device is equipped with support feet 10 at the bottom, which provide stable support for the entire device and ensure that it does not tilt or become unstable during operation. The presence of support feet 10 enhances the overall stability of the device and ensures the smooth progress of the mold making process.

[0035] Through this series of designs, the device not only achieves precise mold fixation but also ensures the stability and reliability of the mold during the production process. The quick disassembly and installation function allows the production line to flexibly adjust the mold style according to needs, greatly improving production efficiency and flexibility.
