Description
A modular mold for producing plastic products Technical Field
[0001] This utility model relates to the field of plastic mold technology, and in particular to a mold for producing composite plastic products. Background Technology
[0002] The field of plastic mold technology refers to a collection of technologies that use specific tools (i.e., molds) and processes to process plastic raw materials into plastic products with specific shapes, sizes, and properties. Modular plastic product production molds, as a special form of plastic molds, consist of multiple mold components. In the mold production process, modular plastic product production molds play a crucial role, not only ensuring product quality and precision but also significantly improving production efficiency and economic benefits.
[0003] Existing modular plastic product manufacturing molds typically use a single, inflexible method for fixing the mold box, making it difficult to accommodate mold boxes of different sizes. This drawback requires operators to make frequent adjustments, resulting in decreased work efficiency. This not only increases production costs but also reduces the flexibility of the equipment, making it difficult to adapt to rapidly changing market demands. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the fixed mold box is relatively simple and lacks flexibility when using the mold for the production of combined plastic products, and it is difficult to adapt to mold boxes of different sizes. Therefore, we propose a mold for the production of combined plastic products.
[0005] To achieve the above objectives, this application adopts the following technical solution: a mold for producing combined plastic products, including a lower mold, a workbench fixed to the top of the lower mold, a mold box provided on the top of the workbench, fixed plates fixed to both sides of the top of the workbench, a push rod slidably connected inside the fixed plate, a clamping plate fixed to one end of the push rod, a fixed shell fixed to the top of the fixed plate, a rotating rod slidably connected inside the fixed shell, a circular plate fixed to one end of the rotating rod, a protrusion fixed to the other end of the rotating rod, a first rotating shaft fixed to both sides of the front end of the protrusion, a connecting rod rotatably connected to the surface of the first rotating shaft, a second rotating shaft rotatably connected to one end of the connecting rod, a moving plate fixed to one end of the second rotating shaft, a locking block fixed to one side of the moving plate, several locking grooves for cooperating with the locking blocks opened on both sides of the push rod, a pull plate slidably connected to the surface of the rotating rod, fixing blocks fixed to both ends of the pull plate, and two fixing holes for cooperating with the fixing blocks opened on both sides of the front end of the fixed shell.
[0006] Preferably, a first spring is rotatably connected to the surface of the rotating rod, one end of the first spring is fixed to the circular plate, and the other end of the first spring is fixed to the pull plate.
[0007] Preferably, sliders are fixed on both sides of the protrusion, and the inside of the fixing shell is provided with a groove for cooperating with the sliders.
[0008] Preferably, a fixing rod is fixed inside the fixed shell, and the surface of the fixing rod is slidably connected to the inside of the movable plate.
[0009] Preferably, a second spring is slidably connected to the surface of the fixed rod, and the two ends of the second spring are fixed to the movable plate.
[0010] Preferably, a mold plate is fixed inside the mold box, a lifting plate is slidably connected inside the mold box, a number of ejector pins are fixed on the top of the lifting plate, a number of demolding holes for cooperating with the ejector pins are opened inside the mold plate, and a third spring is fixed at each of the four corners of the lifting plate, with the other end of the third spring fixed to the mold plate.
[0011] Preferably, a fixing frame is fixed to one end of the top of the lower mold, an electric telescopic rod is installed at the front end of the fixing frame, a push plate is fixed to the output end of the electric telescopic rod, and a collection box is fixed to the front end of the lower mold.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, pulling the pull plate outward causes the fixing block to disengage from the fixing hole, and pulling the rotating rod downward causes the protrusion to move towards the push rod. This causes the first rotating shaft, connecting rod, and second rotating shaft to press against the moving plate, causing the moving plate to move the clamping block to both sides of the fixing shell, thereby releasing the fixation of the push rod. The user can push the push rod to adjust the position of the clamping plate, and the mold box can be adjusted as needed. This allows for flexible adaptation to mold boxes of different sizes, enabling the production of diversified products. It significantly improves the working efficiency and flexibility of the device, reduces production costs, and better meets the diversified needs of the market. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Referring to Figures 1-5, this utility model provides a technical solution: a combined plastic product manufacturing mold, including a lower mold 1, a workbench 2 fixed to the top of the lower mold 1, a mold box 23 provided on the top of the workbench 2, fixed plates 3 fixed on both sides of the top of the workbench 2, a push rod 4 slidably connected inside the fixed plate 3, a clamping plate 5 fixed to one end of the push rod 4, a fixed shell 6 fixed to the top of the fixed plate 3, a rotating rod 7 slidably connected inside the fixed shell 6, a circular plate 33 fixed to one end of the rotating rod 7, a protrusion 8 fixed to the other end of the rotating rod 7, a first rotating shaft 9 fixed to both sides of the front end of the protrusion 8, a connecting rod 10 rotatably connected to the surface of the first rotating shaft 9, a second rotating shaft 11 rotatably connected to one end of the connecting rod 10, a moving plate 12 fixed to one end of the second rotating shaft 11, a locking block 13 fixed to one side of the moving plate 12, and several locking blocks that cooperate with the locking blocks 13 on both sides of the push rod 4. The groove 14 and the rotating rod 7 are slidably connected to a pull plate 15. Both ends of the pull plate 15 are fixed with fixing blocks 16. Two fixing holes 17 are opened on both sides of the front end of the fixing shell 6 to cooperate with the fixing blocks 16. By pulling the pull plate 15 outward, the fixing blocks 16 are disengaged from the fixing holes 17. By pulling the rotating rod 7 downward, the protrusion 8 is moved towards the push rod 4. This causes the first rotating shaft 9, the connecting rod 10, and the second rotating shaft 11 to squeeze the moving plate 12, causing the moving plate 12 to move the locking block 13 to both sides of the fixing shell 6, thereby releasing the fixation of the push rod 4. The user can push the push rod 4 to adjust the position of the clamping plate 5. The mold box 23 can be adjusted as needed, thus flexibly adapting to mold boxes 23 of different sizes, realizing the production of diversified products, significantly improving the working efficiency and flexibility of the device, reducing production costs, and better meeting the diversified needs of the market.
[0022] Referring to Figure 3, in this embodiment: a first spring 18 is rotatably connected to the surface of the rotating rod 7. One end of the first spring 18 is fixed to the circular plate 33, and the other end of the first spring 18 is fixed to the pull plate 15. By setting the structure of the pull plate 15, when the rotating rod 7 is fixed, the pull plate 15 is in a stretched state. When it is necessary to release the fixing of the rotating rod 7, the pull plate 15 is pulled outward and the rebound force of the first spring 18 is used. Under the action of the two, the fixing block 16 is driven to disengage from the interior of the fixing hole 17. The operation is simple and convenient.
[0023] Referring to Figure 4, in this embodiment: sliders 19 are fixed on both sides of the protrusion 8, and a groove 20 that cooperates with the slider 19 is provided inside the fixing shell 6. By setting the structure of slider 19 and groove 20, it is ensured that the protrusion 8 can move smoothly.
[0024] Referring to Figure 4, in this embodiment: a fixing rod 21 is fixed inside the fixing shell 6, and the surface of the fixing rod 21 is slidably connected to the inside of the moving plate 12. By setting the structure of the fixing rod 21, it can be ensured that the moving trajectory of the moving plate 12 does not deviate.
[0025] Referring to Figure 4, in this embodiment: a second spring 22 is slidably connected to the surface of the fixed rod 21. The two ends of the second spring 22 are fixed to the moving plate 12. By setting the structure of the second spring 22, when the push rod 4 is released from fixation, the second spring 22 is in a stretched state, pulling the rotating rod 7 upward to drive the protrusion 8 to move, which drives the first rotating shaft 9, connecting rod 10, and second rotating shaft 11 to squeeze the moving plate 12. At the same time, with the rebound force of the second spring 22, the locking block 13 is smoothly inserted into the slot 14, thereby fixing the push rod 4.
[0026] Referring to Figures 2 and 5, in this embodiment: a mold plate 24 is fixed inside the mold box 23, and a lifting plate 25 is slidably connected inside the mold box 23. Several ejector pins 26 are fixed on the top of the lifting plate 25. Several demolding holes 27 that cooperate with the ejector pins 26 are opened inside the mold plate 24. A third spring 28 is fixed at each of the four corners of the lifting plate 25. The other end of the third spring 28 is fixed to the mold plate 24. By moving the lifting plate 25 upward, the third spring 28 is compressed, which drives the ejector pins 26 to pass through the demolding holes 27 and lift the mold inside the mold box 23. When the mold is separated from the mold plate 24, the lifting plate 25 is released and the rebound force of the third spring 28 drives the lifting plate 25 back to the initial position, thereby simplifying and accelerating the demolding process.
[0027] Referring to Figure 2, in this embodiment: a fixing frame 29 is fixed to one end of the top of the lower mold 1, an electric telescopic rod 30 is installed at the front end of the fixing frame 29, a push plate 31 is fixed to the output end of the electric telescopic rod 30, and a collection box 32 is fixed to the front end of the lower mold 1. By setting the structure of the electric telescopic rod 30, the push plate 31 and the collection box 32, the mold after molding can be automatically pushed out of the mold box 23 and collected into the collection box 32, avoiding manual removal by the operator, improving the removal efficiency, and preventing the residual heat of the mold from causing injury to the operator during manual operation.
[0028] Working principle: By pulling the pull plate 15 outward, the user moves the fixing block 16 out of the fixing hole 17. Pulling the rotating rod 7 downward moves the protrusion 8 towards the push rod 4, causing the first rotating shaft 9, connecting rod 10, and second rotating shaft 11 to compress the moving plate 12. This causes the moving plate 12 to move the locking block 13 to both sides of the fixing shell 6, thereby releasing the fixation of the push rod 4. The user can then push the push rod 4 to adjust the position of the clamping plate 5. The mold box 23 can be adjusted as needed, thus flexibly adapting to mold boxes 23 of different sizes. The production of diversified products significantly improves the efficiency and flexibility of the equipment, reduces production costs, and better meets the diverse needs of the market. By setting up the pull plate 15, when the rotating rod 7 is fixed, the pull plate 15 is in a stretched state. When it is necessary to release the fixing of the rotating rod 7, the pull plate 15 is pulled outwards, and the rebound force of the first spring 18, under the action of both, causes the fixing block 16 to disengage from the fixing hole 17. The operation is simple and convenient. By setting up the slider 19 and the slide groove 20, it is ensured that the protrusion 8 can move smoothly. The setting up of the fixing rod... The structure of 21 ensures that the moving trajectory of the movable plate 12 does not deviate. By setting the structure of the second spring 22, when the push rod 4 is released from its fixed position, the second spring 22 is in a stretched state, pulling the rotating rod 7 upward to move the protrusion 8. This causes the first rotating shaft 9, connecting rod 10, and second rotating shaft 11 to compress the movable plate 12. Simultaneously, the rebound force of the second spring 22 causes the locking block 13 to smoothly insert into the slot 14, thereby fixing the push rod 4. By moving the lifting plate 25 upward, the third spring 28 is compressed, causing the ejector pin 26 to move. The molded part passes through the demolding hole 27 and is pushed up inside the mold box 23. After the mold is separated from the mold plate 24, the lifting plate 25 is released and the rebound force of the third spring 28 drives the lifting plate 25 back to the initial position, thereby simplifying and accelerating the demolding process. By setting the structure of electric telescopic rod 30, push plate 31 and collection box 32, the molded part ejected from the mold box 23 can be automatically pushed out and collected into the collection box 32, avoiding manual removal by the operator, improving the removal efficiency, and preventing the residual heat of the mold from causing damage to the operator during manual operation.
