Description

Technical Field

[0001] This utility model belongs to the field of plastic surface printing technology, and specifically relates to a plastic surface printing mold. Background Technology

[0002] Plastic surface printing molds, as the name suggests, are molds used to print patterns on the surface of plastic products. They are widely used in various plastic products requiring surface decoration, such as automotive parts, appliance housings, electronic product housings, and medical devices. Through printing molds, beautiful and durable patterns or designs can be formed on these products, enhancing their visual appeal and added value. The material of plastic surface printing molds is usually determined based on factors such as the material of the product, printing requirements, and the mold's lifespan. Common mold materials include metal, plastic, and silicone. Metal molds offer advantages such as high precision and high wear resistance, making them suitable for high-precision printing; plastic and silicone molds, on the other hand, are characterized by low cost and ease of processing, making them suitable for printing with general requirements.

[0003] Most existing molds adopt an integrated structure. When the printing mold needs to be replaced, the entire printing mold needs to be disassembled and replaced, which is time-consuming and labor-intensive and inconvenient for daily operation. Secondly, there is no elastic pressing structure inside, making it difficult to elastically press the printing mold onto the plastic surface. This can easily lead to the printing parts not being pressed tightly, thus affecting the printing quality of the plastic. Therefore, it is of great importance to design a plastic surface printing mold to solve the above defects. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic surface printing mold. The main body of the connecting seat solves the problem that under the existing technology, most molds adopt an integrated structure. When it is necessary to replace the printing mold, the entire printing mold needs to be disassembled and replaced, which is time-consuming and laborious and inconvenient for operators' daily operation.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a plastic surface printing mold, which includes a connecting seat body, a mold plate at the bottom of the connecting seat body, connecting components at both ends inside the connecting seat body, and limiting plates slidably connected to both ends outside the connecting seat body, with a fitting component at the top of the limiting plate.

[0008] The connecting assembly is used to install the mold plate and the connecting seat body. The connecting assembly consists of a first limiting rod, a connecting rod, a guide block, a second limiting rod, a limiting ring, and a connecting ring. The first limiting rod is slidably connected to the inside of the connecting seat body, the connecting rod is fixedly connected to the outside of the first limiting rod, the guide block is located at the end of the connecting rod away from the first limiting rod, the second limiting rod is fixedly connected to the outside of the guide block, the limiting ring is fixedly connected to the inside of the connecting seat body and located on the outside of the first limiting rod, and the connecting ring is fixedly connected to the outside of the first limiting rod and located between the limiting ring and the connecting rod.

[0009] When using the connecting seat body of this technical solution, pulling the first limiting rod causes displacement, which in turn causes displacement of the connecting ring, resulting in displacement of the limiting ball. The limiting ball is moved into the inside of the snap-fit ​​groove and connects with the limiting ring, thus limiting the connecting ring and consequently limiting the first limiting rod. Simultaneously, the second limiting rod is also limited. Therefore, the mold plate can be placed inside the connecting seat body. Pressing the first limiting rod causes the first compression spring to pull the moving ring, causing displacement of the first limiting rod and consequently the connecting rod. During the displacement of the connecting rod, the inclined groove causes displacement of the guide block, allowing the second limiting rod to move. The two limiting rods are displaced, connecting the first and second limiting rods to the limiting groove, allowing them to be positioned and connected to the mold plate. This enables the mold plate to be installed inside the connecting seat body. When printing on the plastic surface, the second compression spring drives the sliding block to move, causing the rotating rod to move and the limiting plate to move, thus fitting the limiting plate against the plastic surface. This ensures the stability of the mold plate's clamping and fixing, preventing the plastic from slipping during printing and affecting its printing accuracy. It achieves automatic clamping and fixing of the plastic, improving its practicality and enabling convenient automatic and rapid clamping.

[0010] Preferably, the guide block has an inclined groove inside, and the connecting rod is slidably connected to the inclined groove.

[0011] Furthermore, limiting grooves are provided around the outer perimeter of the mold plate. The internal structure size of the multiple limiting grooves corresponds to the external structure size of the first limiting rod and the second limiting rod. The mold plate is connected to the multiple first limiting rods and the second limiting rods through the multiple limiting grooves.

[0012] Furthermore, multiple sets of limiting balls are fixedly connected to one end of the connecting ring near the limiting ring, and a snap-fit ​​groove is provided on one end of the limiting ring near the connecting ring, through which the limiting ring is connected to the limiting balls.

[0013] Furthermore, a movable ring is fixedly connected to the end of the first limiting rod away from the limiting ring, and a first compression spring is sleeved on the outside of the first limiting rod and between the movable ring and the limiting ring, with the two ends of the first compression spring fixedly connected to the movable ring and the limiting ring respectively.

[0014] Furthermore, the bonding assembly consists of two sets of rotating rods, two sets of sliding blocks, and a sliding rod. Both sets of rotating rods are rotatably connected to the top of the limiting plate, and the sliding blocks are rotatably connected to the end of the rotating rods away from the limiting plate. The sliding rods are located inside the two sets of sliding blocks and are fixedly connected to the inside of the connecting seat body.

[0015] Furthermore, the sliding block and the sliding rod are slidably connected, and a second compression spring is fitted at both ends of the sliding rod and on the outside of the two sets of sliding blocks. Multiple sets of friction strips are fixedly connected to the bottom of the limiting plate.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, through the design of the connecting components, when the mold plate needs to be replaced, pulling the first limiting rod causes the connecting rod to move, which in turn causes the guide block to move, and the second limiting rod to move. The first and second limiting rods are then displaced from inside the limiting groove, allowing the mold plate to be replaced. When installing the mold plate, pressing the first limiting rod causes the limiting ball to move out of the snap-fit ​​groove. The first compression spring pulls the moving ring to move, causing the first limiting rod to move, which in turn causes the connecting rod to move, which in turn causes the guide block to move, and the second limiting rod to move. The first and second limiting rods are then displaced into the limiting groove and connected to the mold plate for limiting connection, allowing the mold plate to be installed. This structure eliminates the need to disassemble the entire printing mold when replacing it, reducing the workload of operators and improving the efficiency of printing mold replacement.

[0019] 2. In this utility model, through the design of the bonding component and the limiting plate, when printing on the surface of plastic, the limiting plate is bonded to the surface of the plastic by the bonding component, so that the limiting plate can limit the plastic, ensure the stability of the mold plate pressing and fixing, and prevent the plastic from accidentally slipping during the printing of the mold plate, which would affect its printing accuracy. It realizes the automatic pressing and fixing action of the plastic, improves its practicality, and thus realizes the function of easy automatic and fast pressing. Attached Figure Description

[0027] This specific embodiment is a plastic surface printing mold, and its structural schematic diagram is shown below. Figure 1-6 As shown, the printing mold includes a connecting seat body 1, a mold plate 2 at the bottom of the connecting seat body 1, connecting components 3 at both ends inside the connecting seat body 1, and a limiting plate 4 slidably connected to both ends outside the connecting seat body 1. A fitting component 5 is provided on the top of the limiting plate 4.

[0028] The connecting assembly 3 is used to install the mold plate 2 and the connecting seat body 1. The connecting assembly 3 consists of a first limiting rod 6, a connecting rod 7, a guide block 8, a second limiting rod 9, a limiting ring 10, and a connecting ring 11. The first limiting rod 6 is slidably connected to the inside of the connecting seat body 1. The connecting rod 7 is fixedly connected to the outside of the first limiting rod 6. The guide block 8 is located at the end of the connecting rod 7 away from the first limiting rod 6. The second limiting rod 9 is fixedly connected to the outside of the guide block 8. The limiting ring 10 is fixedly connected to the inside of the connecting seat body 1 and is located on the outside of the first limiting rod 6. The connecting ring 11 is fixedly connected to the outside of the first limiting rod 6 and is located between the limiting ring 10 and the connecting rod 7.

[0029] Furthermore, the guide block 8 has an inclined groove 12 inside, and the connecting rod 7 is slidably connected to the inclined groove 12. The guide block 8 is slidably connected to the connecting seat body 1. When the connecting rod 7 is displaced, the inclined groove 12 can drive the guide block 8 to be displaced, so that the second limiting rod 9 is displaced.

[0030] The mold plate 2 has limiting grooves 13 on all four sides of its outer side. The internal size of the multiple limiting grooves 13 corresponds to the external size of the first limiting rod 6 and the second limiting rod 9. The mold plate 2 is connected to the first limiting rod 6 and the second limiting rod 9 through the multiple limiting grooves 13. The first limiting rod 6 and the second limiting rod 9 are connected to the limiting grooves 13, so that the first limiting rod 6 and the second limiting rod 9 can be limited and connected to the mold plate 2, thereby installing the mold plate 2 inside the connecting seat body 1.

[0031] Secondly, multiple sets of limiting balls 14 are fixedly connected to one end of the connecting ring 11 near the limiting ring 10. The limiting ring 10 has a snap-fit ​​groove 15 at one end near the connecting ring 11. The limiting ring 10 is connected to the limiting balls 14 through the snap-fit ​​groove 15. When the first limiting rod 6 is displaced, it drives the connecting ring 11 to be displaced, causing the limiting balls 14 to be displaced and moved into the inside of the snap-fit ​​groove 15, where they are connected to the limiting ring 10 for limiting. This allows the limiting ring 10 to limit the connecting ring 11, thereby limiting the first limiting rod 6.

[0032] Furthermore, a movable ring 16 is fixedly connected to the end of the first limiting rod 6 away from the limiting ring 10. A first compression spring 17 is sleeved on the outside of the first limiting rod 6 and between the movable ring 16 and the limiting ring 10. The two ends of the first compression spring 17 are fixedly connected to the movable ring 16 and the limiting ring 10, respectively. By fixing the two ends of the first compression spring 17 to the movable ring 16 and the limiting ring 10, the movable ring 16 is displaced by the first compression spring 17, thereby causing the first limiting rod 6 to move.

[0033] Furthermore, the bonding component 5 consists of two sets of rotating rods 18, two sets of sliding blocks 19, and a sliding rod 20. Both sets of rotating rods 18 are rotatably connected to the top of the limiting plate 4, and the sliding blocks 19 are rotatably connected to the end of the rotating rods 18 away from the limiting plate 4. The sliding rod 20 is located inside the two sets of sliding blocks 19 and is fixedly connected to the inside of the connecting seat body 1. When printing on the surface of the plastic, the bonding component 5 bonds the limiting plate 4 to the surface of the plastic, so that the limiting plate 4 can limit the plastic, ensure the stability of the mold plate 2 in pressing and fixing, and prevent the plastic from accidentally slipping during the printing of the mold plate 2, which would affect its printing accuracy. It realizes the automatic pressing and fixing action of the plastic, improves its practicality, and thus realizes the function of easy automatic and fast pressing.

[0034] Furthermore, the sliding block 19 and the sliding rod 20 are slidably connected. The two ends of the sliding rod 20 and the outer sides of the two sets of sliding blocks 19 are each fitted with a second compression spring 21. The bottom of the limiting plate 4 is fixedly connected with multiple sets of friction strips 22. The second compression spring 21 drives the sliding block 19 to move, causing the rotating rod 18 to move, which in turn drives the limiting plate 4 to move, thus attaching the limiting plate 4 to the surface of the plastic.

[0035] In this embodiment, the specific implementation scenario is as follows: In actual use, pulling the first limiting rod 6 causes displacement, which in turn causes the connecting ring 11 to move, resulting in displacement of the limiting ball 14. The limiting ball 14 is moved into the inside of the snap-fit ​​groove 15 and forms a limiting connection with the limiting ring 10, thus limiting the connecting ring 11. This limits the first limiting rod 6 and simultaneously limits the second limiting rod 9. Therefore, the mold plate 2 can be placed inside the connecting seat body 1. Pressing the first limiting rod 6 causes the moving ring 16 to move through the first compression spring 17, resulting in displacement of the first limiting rod 6. This displacement causes the connecting rod 7 to move, and when the connecting rod 7 moves, the guide block 8 can be moved through the inclined groove 12, causing the second limiting rod 9 to move. The first limiting rod 6 and the second limiting rod 9 are connected to the limiting groove 13, so that the first limiting rod 6 and the second limiting rod 9 can be limited and connected to the mold plate 2, thereby installing the mold plate 2 inside the connecting seat body 1. When printing on the surface of the plastic, the second compression spring 21 drives the sliding block 19 to move, causing the rotating rod 18 to move, which in turn drives the limiting plate 4 to move, so that the limiting plate 4 is attached to the surface of the plastic, ensuring the stability of the mold plate 2 in pressing and fixing, and preventing the plastic from accidentally slipping during the printing process, which would affect the printing accuracy. This invention realizes the automatic pressing and fixing action of the plastic, improving its practicality and thus achieving the function of easy automatic and fast pressing. Compared with the existing printing molds, this utility model can improve the overall practicality of the printing mold through design.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
