Description

Technical Field

[0001] This application relates to the technical field of mold marking, and in particular to a marking device for injection molds. Background Technology

[0002] Injection molds are core process equipment in modern manufacturing for producing plastic products, and they themselves require meticulous labeling management. Typically, after mold manufacturing or repair, a permanent mark needs to be made in a prominent location on the mold (such as the cavity sidewall or base). This mark may include information such as the mold model, cavity number, manufacturing date, and manufacturer's logo. This marking process is crucial for mold asset identification, production traceability, quality control, and inventory management.

[0003] Currently, small and medium-sized workshops generally use handheld marking guns for operation. Although this method has low equipment investment costs and high flexibility, it relies entirely on the operator's experience and feel, which can easily lead to marking position deviation, affecting the aesthetics and readability of the markings. In addition, although there are fully automatic, highly integrated large CNC marking centers on the market that can solve the accuracy and stability problems, their procurement costs are high, further increasing the operating costs of enterprises and making it difficult to widely adopt them in small and medium-sized enterprises. Utility Model Content

[0004] The purpose of this application is to provide a marking device for injection molds, which solves the problem that the marking position is easily offset when manually using a handheld marking gun, affecting the aesthetics and readability of the marking. The high purchase cost of large CNC marking devices increases the operating costs of enterprises and makes it difficult to widely adopt them in small and medium-sized enterprises.

Then, the operator can easily transport the device to any mold to be marked in the workshop without having to carry heavy molds. During marking, the operator controls the height of the marking gun through the first linear module and flexibly adjusts the horizontal position of the marking gun through the second linear module. This solves the problem of marking position deviation that is easy to occur when manually holding the marking gun, which affects the aesthetics and readability of the marking. Moreover, the device has a simple structure and no complicated electrical structure, making it easier to promote and apply in small and medium-sized mold enterprises.

A second scale 8 is fixedly connected to one side surface of the second housing 401. Through the arrangement of the first linear module 3, the second linear module 4, the power controller 2, the first pointer 5, the second pointer 7, the first scale 6, the second scale 8, and the mounting base 9, the device can fix the marking gun on the mounting base 9 during use. The power controller 2 facilitates convenient circuit connection, allowing operators to easily transport the device to any mold to be marked in the workshop without the need to move heavy molds. During marking, the operator controls the height of the marking gun using the first linear module 3, while the second linear module 4 flexibly adjusts the horizontal position of the marking gun. The coordination of the first pointer 5, the second pointer 7, and the corresponding first scale 6 and second scale 8 further ensures adjustment accuracy, enabling precise marking. This solves the problem of marking position deviation that easily occurs when manually holding the marking gun, affecting the aesthetics and readability of the markings. Furthermore, the device has a simple structure and no complex electrical components, making it easier to promote and apply in small and medium-sized mold enterprises.

[0019] Example 2: Marking device for injection molds, refer to Figure 3 , Figure 4 and Figure 5A fixed shell 19 is fixedly connected to the upper surface of the first housing 301. A first bevel gear 10 is rotatably connected to the upper surface of the first housing 301. The first bevel gear 10 is fixedly connected to a first lead screw 302. A second bevel gear 11 is rotatably connected to the inner wall of one side of the fixed shell 19. The second bevel gear 11 meshes with the first bevel gear 10. A first synchronous pulley 12 is rotatably connected to one side surface of the fixed shell 19 and one side surface of the first housing 301. A first transmission belt 13 is drivingly connected between the two first synchronous pulleys 12. One first synchronous pulley 12 is fixedly connected to the second bevel gear 11, and a first hand crank 14 is fixedly connected to the surface of the other first synchronous pulley 12. An annular groove is opened on one side surface of the second housing 401 and a support plate 15 is rotatably connected to it. Two second synchronous pulleys 16 are rotatably connected to the side of the support plate 15. A second transmission belt 17 is connected between the pulleys 16. One of the second synchronous pulleys 16 is fixedly connected to the second lead screw 402. A second hand crank 18 is fixedly connected to one side surface of the second synchronous pulley 16. Through the arrangement of the first bevel gear 10, the second bevel gear 11, the first synchronous pulley 12, the second synchronous pulley 16, the first hand crank 14, and the second hand crank 18, when the operator operates the first linear module 3, he only needs to rotate the first hand crank 14 with the appropriate height. This will drive the second bevel gear 10 to rotate through the two first synchronous pulleys 12, thereby adjusting the height of the marking gun. When operating the second linear module 4, the operator can select the second hand crank 18 that matches the operating posture according to the height of the second linear module 4 and his own height. There is no need to bend over or stand on tiptoe to operate, which effectively reduces fatigue during long-term operation and improves operating comfort and adjustment efficiency.

[0020] The implementation principle of this application embodiment is as follows: Before use, the marking gun is fixed on the mounting base 9 through several through holes inside the mounting base 9. Then, the power controller 2 is connected to the marking gun. Then, the vehicle body 1 is pushed to move to the side of the marking mold in the workshop to complete the pre-operation preparation. During the marking operation, if it is necessary to adjust the height of the marking gun, the operator can rotate the first hand crank 14. The first hand crank 14 drives one of the first synchronous pulleys 12 fixedly connected to it to rotate. The first synchronous pulley 12 drives the other fixed first synchronous pulley 12 to rotate through the first transmission belt 13, thereby causing the second bevel gear 11 to rotate. After the second bevel gear 11 rotates, the first bevel gear 10 rotates. After the first bevel gear 10 rotates, it drives the first lead screw 302 to rotate. The first lead screw 302 then causes the first moving block 303 connected to the outer thread to move. When moving, the first finger on the side of the first moving block 303... The needle 5 moves, and the operator can accurately control the height adjustment of the marking gun through the corresponding scale of the first pointer 5 and the first scale 6. If it is necessary to adjust the horizontal position of the marking gun, the operator can first rotate one of the second hand cranks 18 according to the height of the second linear module 4 and his own height. The second hand crank 18 drives one of the second synchronous pulleys 16 fixedly connected to it to rotate. The second synchronous pulley 16 drives the other second synchronous pulley 16 to rotate synchronously through the second transmission belt 17. After the second synchronous pulley 16 rotates, the second lead screw 402 rotates, and then the second moving block 403 moves. When the second moving block 403 moves, the second pointer 7 moves accordingly. At this time, the operator can accurately control the horizontal position adjustment of the marking gun through the corresponding scale of the second pointer 7 and the second scale 8. After the height and horizontal position of the marking gun are adjusted to the marking area, the marking gun can be started to complete the precise marking operation.
