Description

Technical Field

[0001] This utility model relates to the field of molding dies, specifically a positioning molding die for processing membrane switch panels. Background Technology

[0002] A membrane switch is an operating system that integrates button functions, indicator elements, and an instrument panel. It consists of four parts: a panel, an upper circuit, an isolation layer, and a lower circuit. When the membrane switch is pressed, the contacts of the upper circuit deform downwards and make contact with the plates of the lower circuit to conduct electricity. When the finger is released, the contacts of the upper circuit bounce back, the circuit is broken, and the circuit triggers a signal. Membrane switches have a rigorous structure, beautiful appearance, good sealing, moisture resistance, and long service life. They are widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, automotive industry, smart toys, and home appliances. However, the processing of membrane switch panels requires the use of positioning and molding molds.

[0003] The existing positioning and forming mold is manually placed on the platform, then manually pushed to the stamping platform for stamping. After stamping, it is manually pulled out and removed to place a new membrane switch for further processing. This method has low work efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a positioning and forming mold for processing membrane switch panels, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and forming mold for processing a membrane switch panel, comprising a base, a support frame fixed to the top of the base, and a cylinder disposed inside the support frame, with a pressure plate fixed to the output end of the cylinder, a placement platform movably mounted on the top of the base, and a driving structure for moving the placement platform disposed on the top of the base, the driving structure comprising a rotating rod, a sprocket, and a chain, two sets of rotating rods movably mounted on the top of the base, with a sprocket sleeved on the outer wall of the rotating rod, and a chain sleeved on the outer wall of the sprocket, the chain being fixedly connected to the bottom of the placement platform, and two sets of grooves formed on the top of the placement platform.

[0006] By adopting the above technical solution, the problem of low processing efficiency of existing membrane switch panels is solved. The membrane switch panels can be placed in two sets of grooves. The chain drives the placement table to move. One set of grooves is located under the pressure plate and the other set of grooves is located on the outside. The stamped membrane switch is removed and a new membrane switch panel is placed. This method improves work efficiency.

[0007] The present invention is further configured such that a drive assembly is provided at the end of one set of the rotating rods, and the rotating rods are controlled to rotate by the drive assembly.

[0008] Preferably, the motor drives the rotating rod to rotate when it is working, replacing the method of manually rotating the rotating rod.

[0009] The present invention is further configured such that the bottom of the placement platform is equipped with multiple sets of moving wheels, and the top of the base is provided with a moving groove.

[0010] Preferably, the movable wheels can reduce the friction between the placement platform and the base, and the movable groove can conveniently limit the movement direction of the placement platform.

[0011] The present invention is further configured such that limiting components are provided on both sides of the pressure plate to position the placement platform. The limiting components include limiting rods fixed on both sides of the pressure plate, and multiple sets of limiting grooves are provided on the top of the placement platform.

[0012] Preferably, the placement platform can be limited by the setting of the limiting component. When the cylinder drives the pressure plate to move downward, the limiting rod and the limiting groove cooperate with each other to limit the placement platform, so that the placement platform is located directly below the pressure plate, and the processing accuracy is higher.

[0013] The present invention is further configured such that the end of the limiting rod is tapered and the inner wall of the limiting groove is inclined.

[0014] Preferably, the tapered limiting rod can easily enter the interior of the limiting groove when moving downwards, thereby correcting the placement platform so that the groove is located directly below the pressure plate.

[0015] The present invention is further configured such that multiple sets of fixing blocks are fixed to the top of the base, and the fixing blocks are connected to the rotating rod bearing.

[0016] Preferably, the fixed block facilitates the installation of the rotating rod, allowing it to be mounted above the base and reducing friction between the rod and the base.

[0017] The present invention is further configured such that the number of chains is two sets, and the two sets of chains are symmetrically arranged about the vertical center line of the base.

[0018] Preferably, the placement platform can be moved more effectively by using two sets of chains.

[0019] The present invention is further configured such that the bottom of the placement platform does not contact the top of the base, and the support frame is located in the middle of the base.

[0020] Preferably, the placement platform does not contact the base to reduce friction between them, and the support frame is located in the middle of the base to facilitate the processing of the membrane switch panel.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model solves the problem of low processing efficiency of existing membrane switch panels by setting up a placement platform, grooves, rotating rods, sprockets and chains. The two sets of grooves can place the membrane switch panels, and the chain drives the placement platform to move. One set of grooves is located below the pressure plate and the other set of grooves is located on the outside. The stamped membrane switch is removed and a new membrane switch panel is placed. This method improves work efficiency.

[0023] 2. This utility model has a limiting component, which can limit the placement platform. When the cylinder drives the pressure plate to move downward, the limiting rod and the limiting groove cooperate to limit the placement platform, so that the placement platform is located directly below the pressure plate, resulting in higher processing accuracy.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] First embodiment:

[0034] Please see Figures 1-3 The system includes a base 1, a support frame 2 fixed to the top of the base 1, a cylinder 3 inside the support frame 2, a pressure plate 4 fixed to the output end of the cylinder 3, a placement platform 5 movably mounted on the top of the base 1, and a drive structure for moving the placement platform 5. The drive structure includes a rotating rod 8, a sprocket 9, and a chain 10. When the motor works, it drives the rotating rod 8 to rotate, which in turn drives the sprocket 9 to rotate, which in turn drives the chain 10 to rotate. The rotation of the chain 10 causes the placement platform 5 to move. The placement platform 5 drives the moving wheel 14 to slide on the inner wall of the moving groove 11. Two sets of rotating rods 8 are movably mounted on the top of the base 1, and the outer wall of the rotating rod 8 is fitted with a sprocket 9. The outer wall of the sprocket 9 is fitted with a chain 10, and the chain 10 is fixedly connected to the bottom of the placement platform 5. Two sets of grooves 6 are opened on the top of the placement platform 5. The two sets of grooves 6 can improve the processing efficiency and eliminate the need to stop and wait.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A drive assembly is provided at the end of a set of rotating rods 8. The drive assembly is a motor 7. The rotating rods 8 are controlled to rotate by the drive assembly. When the motor 7 is working, it drives the rotating rods 8 to rotate, which replaces the method of manually rotating the rotating rods 8.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The bottom of the placement platform 5 is equipped with multiple sets of moving wheels 14, and the top of the base 1 is provided with a moving groove 11. The moving wheels 14 can reduce the friction between the placement platform 5 and the base 1, and the moving groove 11 can conveniently limit the movement direction of the placement platform 5.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 Multiple sets of fixing blocks 15 are fixed to the top of the base 1, and the fixing blocks 15 are connected to the rotating rod 8 by bearings. The fixing blocks 15 make it easy to install the rotating rod 8, so that the rotating rod 8 is installed above the base 1, reducing the friction between the rotating rod 8 and the base 1.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 There are two sets of chains 10, which are symmetrically arranged around the vertical center line of the base 1. The two sets of chains 10 can better drive the placement platform 5 to move.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2The bottom of the placement platform 5 does not contact the top of the base 1, and the support frame 2 is located in the middle of the base 1. The fact that the placement platform 5 does not contact the base 1 can reduce the friction between them. The support frame 2 is located in the middle of the base 1 to facilitate the processing of the membrane switch panel.

[0040] Second embodiment:

[0041] Please see Figures 2-5 Limiting components are provided on both sides of the pressure plate 4 to position the placement table 5. The limiting components include limiting rods 13 fixed on both sides of the pressure plate 4. Multiple sets of limiting grooves 12 are opened on the top of the placement table 5. When the cylinder 3 drives the pressure plate 4 to move downward, the limiting rods 13 and the limiting grooves 12 cooperate with each other to limit the placement table 5, so that the placement table 5 is located directly below the pressure plate 4, and the processing accuracy is higher.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 5 The end of the limiting rod 13 is tapered, and the inner wall of the limiting groove 12 is inclined. The tapered limiting rod 13 can easily enter the interior of the limiting groove 12 when moving downward, thereby correcting the placement platform 5 so that the groove 6 is located directly below the pressure plate 4.

[0043] In practical operation, the following steps are taken: The membrane switch panel to be processed is placed inside the two sets of grooves 6. Then, the motor 7 is started, driving the rotating rod 8 to rotate. The rotating rod 8 drives the sprocket 9 to rotate, which in turn drives the chain 10 to rotate. The chain 10 then moves the placement platform 5, causing the moving wheel 14 to slide along the inner wall of the moving groove 11. When one set of grooves 6 moves below the pressure plate 4, the motor 7 stops, and the placement platform 5 stops moving. The cylinder 3 then moves the pressure plate 4 downwards to process the membrane switch panel. After processing, the cylinder 3 moves the pressure plate 4 back to its original position. The motor 7 then drives the rotating rod 8 to continue rotating, moving the placement platform 5. When the other set of grooves 6 moves below the pressure plate 4, the motor 7 stops, and the cylinder 3 moves the pressure plate 4. The membrane switch panel inside the groove 6 is manually removed, and the processed membrane switch panel is placed inside. The above steps are then repeated.
