Description

Technical Field

[0001] The utility model relates to the technical field of silicone part production and processing, in particular to a stamping machine for silicone parts. Background Technique

[0002] Silicone parts refer to parts made of silicone rubber, which have many excellent properties, such as high temperature resistance, low temperature resistance, anti-aging, good insulation performance, etc. These properties make silicone parts widely used in many fields such as electronics, machinery, automobiles, construction, chemical industry, food, etc. By using a stamping machine in cooperation with a mold corresponding to the requirements, silicone parts with complex contours and structures can be processed to meet diverse design requirements.

[0003] However, usually before stamping silicone parts, it is necessary to manually place each silicone product on the corresponding position of the mold one by one so that the stamping machine can accurately stamp it. However, when manually placing silicone products back and forth many times, it may be difficult to ensure that each silicone product is accurately placed at the same position on the mold at one time. Most of them need to spend a lot of time adjusting and aligning the corners. Especially in large-scale production, this will increase production costs and error rates, and workers need to approach the stamping machine or other mechanical equipment, which increases the risk of work-related injury accidents and results in a decrease in production and processing efficiency. Content of the Utility Model

[0004] The utility model discloses a stamping machine for silicone parts, aiming to solve the technical problem that usually before stamping silicone parts, it is necessary to manually place each silicone product on the corresponding position of the mold one by one so that the stamping machine can accurately stamp it. However, when manually placing silicone products back and forth many times, it may be difficult to ensure that each silicone product is accurately placed at the same position on the mold at one time. Most of them need to spend a lot of time adjusting and aligning the corners. Especially in large-scale production, this will increase production costs and error rates, and workers need to approach the stamping machine or other mechanical equipment, which increases the risk of work-related injury accidents and results in a decrease in production and processing efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A stamping machine for silicone parts includes a mounting base, the mounting base includes a mounting frame and a fixing plate, and six support columns are provided on the outer wall of the bottom of the mounting base. It further includes:

[0007] An aggregate mechanism: located at the top of the mounting frame;

[0008] Pushing mechanism: Located on one inner wall of the mounting frame, the pushing mechanism includes two second motors. On one outer wall of adjacent two support columns, there is a connecting plate. On the top outer wall of the connecting plate, there is a mounting plate. On one outer wall of the mounting plate, two third connecting rods are hinged. The output shaft of the third second motor is fixedly connected with a first connecting rod. A second connecting rod is hinged between the third connecting rod and the first connecting rod. On one outer wall of the second connecting rod, there is a limit block. On the top outer walls of the two limit blocks, there is a push rod. On the top outer wall of the push rod, there are four equally spaced partitions. The aggregate mechanism is located between adjacent two partitions;

[0009] Limiting mechanism: Located on both sides of the fixed plate;

[0010] Stamping mechanism: Located on the top of the fixed plate.

[0011] During use, the worker sequentially and orderly places multiple silicone parts in the aggregate mechanism, and then starts the two second motors. The output shafts of the second motors drive the first connecting rods to rotate. The rotation of the first connecting rods is transmitted to the third connecting rods through the second connecting rods. Due to the hinged relationship between the first connecting rod, the second connecting rod, and the third connecting rod, and with the second connecting rod limited by the limit block, it is ensured that the second connecting rod and the third connecting rod move on a specific trajectory, thereby converting the rotational motion driven by the second motor into a linear reciprocating motion of the push rod. There are multiple partitions on the top of the push rod, which are mainly used to separate and position the aggregate mechanism, thereby ensuring that the aggregate mechanism can move orderly under the push of the push rod, and at the same time preventing multiple silicone parts from mixing during the transportation of the aggregate mechanism. Then, the multiple silicone parts are sequentially transported to directly below the stamping mechanism through the aggregate mechanism, limited by the limiting mechanism, and finally the silicone parts are stamped by the stamping mechanism. This device can reduce the time cost that workers spend on aligning the silicone parts to the specified positions of the mold, improve the production and processing efficiency, reduce the production cost and error rate at the same time, lighten the work burden of workers, avoid workers directly contacting the equipment, and reduce potential safety hazards.

[0012] In a preferred solution, the aggregate mechanism includes two conveying boxes. On the top outer wall of the mounting seat, there are two sliding grooves. Inside the conveying box, there is a lower stamping plate. On the top outer wall of the lower stamping plate, there are several limiting ports. On the bottom outer wall of the conveying box near both sides, there are moving blocks, and the moving blocks are slidably connected to the inner walls of the sliding grooves.

[0013] In this solution, during use, first place the silicone part on the upper surface of the lower stamping plate. The limiting openings on the lower stamping plate coincide with the parts of the silicone part to be stamped. The moving blocks provided at the bottom of the conveying box move along the inner wall of the chute towards the stamping mechanism under the push of the material pushing mechanism. This setting avoids workers making multiple round trips between the rack loaded with silicone parts and the stamping mechanism, reduces the workload of workers, and improves the production and processing efficiency.

[0014] In a preferred solution, the limiting mechanism includes two connecting frames, both of which are installed on one outer wall of the fixed frame. A first motor and two limiting rods are provided on the top outer wall of one of the connecting frames. The output shaft of the first motor is fixedly connected to a threaded rod. One end of the threaded rod is connected to the bottom outer wall of one of the connecting frames through a bearing. A limiting baffle is connected to the circumferential outer wall of the threaded rod through a thread, and the limiting baffle penetrates through one end of the two limiting rods.

[0015] In this solution, during use, start the first motor. The output shaft of the first motor drives the threaded rod to rotate. Since the threaded rod is connected to the limiting baffle through a thread, under the limiting action of the two limiting rods on the limiting baffle, when the limiting baffle rotates with the screw rod, it moves up and down on the circumferential surface of the threaded rod. When it is necessary to limit the conveying box, the limiting baffle moves downward on the circumferential surface of the threaded rod and smoothly engages with the inner wall of the chute, thereby limiting both sides of the conveying box to prevent the conveying box from moving under high-speed stamping, and further avoiding affecting the processing quality of the silicone part. After stamping the silicone part, the limiting baffle moves upward on the circumferential surface of the threaded rod, and then under the push of the material pushing mechanism, the conveying box moves and leaves the surface of the fixed plate, and at the same time, the next conveying box moves to directly below the fixed frame for stamping processing of its silicone part.

[0016] As can be seen from the above, a stamping machine for silicone parts includes a mounting base. The mounting base includes a mounting frame and a fixed plate. Six support columns are provided on the bottom outer wall of the mounting base. It also includes:

[0017] An aggregate mechanism: located at the top of the mounting frame;

[0018] A material pushing mechanism: located on one inner wall of the mounting frame. The material pushing mechanism includes two second motors. A connecting plate is provided on one outer wall of adjacent two support columns. A mounting plate is provided on the top outer wall of the connecting plate. Two third connecting rods are hinged on one outer wall of the mounting plate. The output shaft of the third second motor is fixedly connected to a first connecting rod. A second connecting rod is hinged between the third connecting rod and the first connecting rod. A limiting block is provided on one outer wall of the second connecting rod. Push rods are provided on the top outer walls of the two limiting blocks. Four equally spaced partitions are provided on the top outer wall of the push rod. The aggregate mechanism is located between adjacent two partitions;

[0019] Limit mechanism: located on both sides of the fixed plate;

[0020] Stamping mechanism: located on the top of the fixed plate. The stamping machine for silicone parts provided by the present utility model has the technical effects of being able to reduce the time cost for workers to align the silicone parts to the designated positions of the mold, improving the production and processing efficiency, reducing the production cost and error rate at the same time, lightening the work burden of workers, avoiding direct contact between workers and the equipment, and reducing potential safety hazards.

Detailed Description of the Invention

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0028] A punching machine for silicone parts disclosed by the utility model is mainly applied to the situation that before punching silicone parts, it is usually necessary to manually place silicone products one by one at the corresponding positions of the mold so that the punching machine can accurately punch them. However, when manually placing silicone products back and forth many times, it may be difficult to ensure that each silicone product is accurately placed at the same position of the mold at one time. Most of them need to spend a lot of time adjusting and aligning the edges and corners. Especially in large-scale production, this will increase the production cost and error rate, and workers need to approach the punching machine or other mechanical equipment, which increases the risk of work-related injury accidents and results in a reduction in production and processing efficiency.

[0029] Refer to Figure 1 、 Figure 2 and Figure 3 A punching machine for silicone parts includes a mounting base. The mounting base includes a mounting frame 1 and a fixing plate. Six support columns are provided on the outer wall of the bottom of the mounting base. It further includes:

[0030] An aggregate mechanism: located at the top of the mounting frame 1;

[0031] A material pushing mechanism: located on one inner wall of the mounting frame 1. The material pushing mechanism includes two second motors. A connecting plate 3 is provided on the outer wall of one side of adjacent two support columns. An installation plate 4 is provided on the outer wall of the top of the connecting plate 3. Two third connecting rods 17 are hinged on the outer wall of one side of the installation plate 4. The output shaft of the second motor is fixedly connected with a first connecting rod 14. A second connecting rod 16 is hinged between the third connecting rod 17 and the first connecting rod 14. A limiting block 15 is provided on the outer wall of one side of the second connecting rod 16. Four equally spaced partitions are provided on the outer wall of the top of the two limiting blocks 15. The aggregate mechanism is located between adjacent two partitions;

[0032] A limiting mechanism: located on both sides of the fixing plate;

[0033] A punching mechanism: located on the top of the fixing plate.

[0034] Wherein, two installation boxes 22 are provided on the outer wall of one side of the installation plate 4 away from the two third connecting rods 17, and the two second motors are respectively installed on the inner wall of the two installation boxes 22.

[0035] Specifically, during use, workers sequentially and orderly place multiple silicone parts into the aggregate mechanism, and then start two second motors. The output shafts of the second motors drive the first connecting rod 14 to rotate. The rotation of the first connecting rod 14 is transmitted to the third connecting rod 17 through the second connecting rod 16. Due to the hinged relationship among the first connecting rod 14, the second connecting rod 16, and the third connecting rod 17, and with the second connecting rod 16 being limited by the limit block 15, it is ensured that the second connecting rod 16 and the third connecting rod 17 move along a specific trajectory. Thus, the rotational motion driven by the second motor is converted into the linear reciprocating motion of the push rod 6. The top of the push rod 6 is provided with multiple partition plates mainly for separating and positioning the aggregate mechanism, thereby ensuring that the aggregate mechanism can move orderly under the push of the push rod 6, and at the same time preventing multiple silicone parts from being mixed during the transportation of the aggregate mechanism. Then, the multiple silicone parts are sequentially transported to directly below the stamping mechanism by the aggregate mechanism, limited by the limiting mechanism, and finally the silicone parts are stamped by the stamping mechanism. This device can reduce the time cost for workers to align the silicone parts with the specified positions of the mold, improve the production and processing efficiency, reduce the production cost and error rate at the same time, lighten the work burden of workers, avoid workers directly contacting the equipment, and reduce potential safety hazards.

[0036] Referring to Figure 1 , Figure 2 and Figure 5 , in a preferred embodiment, the aggregate mechanism includes two conveying boxes 5. Two sliding grooves 7 are opened on the top outer wall of the mounting seat. The inside of the conveying box 5 is provided with a lower stamping plate 13. A number of limiting ports are opened on the top outer wall of the lower stamping plate 13. Moving blocks 2 are provided at both sides near the bottom outer wall of the conveying box 5, and the moving blocks 2 are slidably connected to the inner wall of the sliding groove 7.

[0037] It should be noted that the lower stamping plate 13 is the same size as the silicone part, and there is still a certain distance between the upper surface of the lower stamping plate 13 and the top of the conveying box 5, so as to limit the silicone part and prevent the silicone part from falling during transportation.

[0038] Among them, the inside of the lower stamping plate 13 is a hollow structure. This setting is to facilitate that after the stamping mechanism stamps the silicone part, the residue and debris containing the silicone part directly fall into the inside of the lower stamping plate 13 for centralized collection, avoiding the debris from scattering everywhere.

[0039] Specifically, during use, first place the silicone part on the upper surface of the lower stamping plate 13. The limiting ports on the lower stamping plate 13 coincide with the parts of the silicone part to be stamped. The moving blocks 2 provided at the bottom of the conveying box 5 move along the inner wall of the sliding groove 7 towards the stamping mechanism under the push of the pushing mechanism. This setting avoids workers making multiple round trips between the rack loaded with silicone parts and the stamping mechanism, lightens the work burden of workers, and improves the production and processing efficiency.

[0040] Referring toFigure 1 and Figure 3 , in a preferred embodiment, the stamping mechanism includes four fixed sleeves 9 and electric telescopic rods. A fixed frame 8 is provided on the outer wall of the top of the fixed plate. The electric telescopic rods and the four fixed sleeves 9 are both located on the outer wall of the bottom of the fixed frame 8. The movable end of the electric telescopic rod is provided with an upper stamping plate 11. Four mounting rods 10 are provided on the outer wall of the top of the upper stamping plate 11. The mounting rods 10 are slidably connected to the inner walls of the fixed sleeves 9.

[0041] Specifically, when the conveying box 5 moves to directly below the fixed frame 8 under the push of the pushing mechanism, the two sides of the conveying box 5 are limited and fixed by the limiting mechanism. At the same time, under the limitation of the two sliding grooves 7, the electric telescopic rod is started. The movable end of the electric telescopic rod drives the upper stamping plate 11 to move downward, so as to stamp the silica gel part on the upper surface of the lower stamping plate 13. The arranged mounting rods 10 will slide on the inner walls of the fixed sleeves 9 as the movable end of the electric telescopic rod extends or retracts, so as to limit the upper stamping plate 11 and improve the stability of the upper stamping plate 11 when moving up and down.

[0042] Referring to Figure 1 , Figure 3 and Figure 4 , in a preferred embodiment, the limiting mechanism includes two connecting frames 18. The two connecting frames 18 are both installed on one outer wall of the fixed frame 8. A first motor 20 and two limiting rods 19 are provided on the outer wall of the top of one of the connecting frames 18. The output shaft of the first motor 20 is fixedly connected with a threaded rod 21. One end of the threaded rod 21 is connected to the outer wall of the bottom of one of the connecting frames 18 through a bearing. A limiting baffle 12 is threadedly connected to the circumferential outer wall of the threaded rod 21. The limiting baffle 12 penetrates through one end of the two limiting rods 19.

[0043] Among them, the limiting baffle 12 is of a "U" - shaped structure. The limiting baffle 12 is clamped to the inner walls of the two sliding grooves 7. When the "U" - shaped limiting baffle 12 moves downward, it can cooperate with the sliding grooves 7 to limit the two sides and both sides of the conveying box 5 at the same time, so as to prevent the conveying box 5 from displacing during the stamping process.

[0044] Specifically, during use, the first motor 20 is started, and the output shaft of the first motor 20 drives the threaded rod 21 to rotate. Since the threaded rod 21 is threadedly connected to the limit baffle 12, under the limiting effect of the two limit rods 19 on the limit baffle 12, when the limit baffle 12 rotates with the screw rod, it moves up and down on the circumferential surface of the threaded rod 21. When it is necessary to limit the conveying box 5, the limit baffle 12 moves downward on the circumferential surface of the threaded rod 21 and is smoothly clamped on the inner wall of the chute 7, thereby limiting both sides of the conveying box 5 to prevent the conveying box 5 from moving under high-speed stamping, and further avoiding affecting the processing quality of the silicone parts. After stamping the silicone parts, the limit baffle 12 moves upward on the circumferential surface of the threaded rod 21, and then under the push of the pushing mechanism, the conveying box 5 moves and leaves the surface of the fixed plate, and at the same time, the next conveying box 5 moves to directly below the fixed frame 8 for stamping processing of its silicone parts.

[0045] Working principle: During use, the worker sequentially and orderly places multiple silicone parts in the aggregate mechanism, and then starts the two second motors. The output shafts of the second motors drive the first connecting rod 14 to rotate. The rotation of the first connecting rod 14 is transmitted to the third connecting rod 17 through the second connecting rod 16. Due to the hinged relationship between the first connecting rod 14, the second connecting rod 16, and the third connecting rod 17, and with the second connecting rod 16 limited by the limit block 15, it is ensured that the second connecting rod 16 and the third connecting rod 17 move on a specific trajectory, so that the rotational motion driven by the second motor is converted into the linear reciprocating motion of the push rod 6. Multiple partitions are provided at the top of the push rod 6 mainly for separating and positioning the aggregate mechanism, thereby ensuring that the aggregate mechanism can move orderly under the push of the push rod 6, and at the same time preventing multiple silicone parts from being mixed during the conveying of the aggregate mechanism. Then, the multiple silicone parts are sequentially conveyed to directly below the stamping mechanism through the aggregate mechanism, limited by the limiting mechanism, and finally the stamping mechanism stamps the silicone parts.

[0046] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of some structures, devices, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
