Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, specifically to a punching machine for injection molds. Background Technology

[0002] In modern manufacturing, injection mold punching machines are a key processing equipment widely used in many fields such as automobile manufacturing, electronics, and packaging materials. They are used to perform precise punching operations on injection-molded products to meet specific needs for product function, assembly, or appearance design. With the continuous advancement of industrial technology and the increasing market demands for product quality and production efficiency, the performance and functions of injection mold punching machines are constantly being optimized and upgraded.

[0003] Currently, most injection mold punching machines on the market use bolts or complex mechanical locking structures to connect the punching cutter head to the mounting base. While this design ensures the stability of the punching cutter head during operation to some extent, when it is necessary to replace punching cutter heads of different specifications or those that are worn, operators need to use special tools to gradually disassemble multiple bolts or unlock complex mechanical structures in a specific order. This process is cumbersome and time-consuming, which not only increases equipment downtime and reduces production efficiency, but also places higher demands on the professional skills of operators and increases labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide an injection mold punching machine to solve the problem mentioned in the background art. Currently, injection mold punching machines on the market mostly use bolt fixing or complex mechanical locking structures to connect the punching cutter head to the mounting base. Although this design ensures the stability of the punching cutter head during operation to a certain extent, when it is necessary to replace punching cutter heads of different specifications or worn ones, operators need to use special tools to gradually disassemble multiple bolts or unlock complex mechanical structures in a specific order. The process is cumbersome and time-consuming, which not only increases the downtime of the equipment and reduces production efficiency, but also places higher demands on the professional skills of operators and increases labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching machine for injection molds, comprising a base, a processing table fixedly mounted at the center of the top of the base, a top frame fixedly mounted on the outer side of the top of the base, a support seat at the center of the bottom of the top frame, a mounting seat fixedly connected to the center of the bottom of the support seat, a punching cutter disc at the bottom of the mounting seat, a connecting plate fixedly connected to the center of the top of the punching cutter disc, an installation groove at the center of the bottom of the mounting seat, the top of the connecting plate penetrating into the installation groove and engaging with the installation groove, movable grooves on both sides of the mounting seat corresponding to the installation groove, fixed grooves on both sides of the connecting plate, a movable block slidably connected to one side of the movable groove, and two movable blocks on the left and right sides facing each other. Each side is fixedly connected to a fixing block. The side of the fixing block away from the movable block extends into the interior of the fixing groove and engages with the fixing groove. The two movable blocks on the left and right are fixedly connected to movable columns on opposite sides. The bottom positions of both sides of the mounting base are fixedly connected to an outer plate one. The sides of the punching cutter head are fixedly connected to an outer plate two. The side of the movable column away from the movable block extends into the exterior of the outer plate one. A groove is formed on one side of the movable column. A limiting short rod is fixedly connected to one side of the groove. A locking rod is fixedly connected to the top of the outer plate two. The top of the locking rod extends through the groove and the outer plate one and extends to the outside of the outer plate one. A limiting groove is formed on one side of the locking rod near the top. One side of the limiting short rod extends into the limiting groove and engages with the limiting groove.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This injection mold punching machine, through the snap-fit ​​design of the movable column, fixed block, and fixed groove, combined with the limiting structure of the locking rod and the limiting groove, achieves rapid disassembly and assembly of the punching cutter head and the mounting base. During operation, only the fixing bolts need to be removed, and the movable column needs to be pulled outward to disengage the limiting rod from the limiting groove, thus releasing the locking rod. Then, the punching cutter head can be directly removed from the mounting groove without removing multiple bolts or unlocking complex mechanical structures. Compared with traditional bolt-fixed or mechanically locked structures, this design reduces disassembly and assembly time by approximately %, effectively reducing equipment downtime and significantly improving production efficiency. Traditional punching cutter head replacement requires professional technicians to use special tools and operate step by step in a specific sequence, which requires high operator skills. However, this design, through the cooperation of the movable column and the return spring, realizes the automation and mechanization of the disassembly and assembly process. Operators only need to pull the movable column to complete the disassembly and assembly, without complex tools or professional skills. This improvement allows ordinary workers to complete the replacement of the punching cutter head, reducing reliance on highly skilled personnel and reducing labor costs. Attached Figure Description

During operation, only the fixing bolt 26 needs to be removed, and the movable column 19 needs to be pulled outward to disengage the limiting rod 21 from the limiting groove 23, thereby releasing the fixing of the locking rod 22. Then, the punching cutter head 8 can be directly removed from the mounting groove 12 without removing multiple bolts or unlocking complex mechanical structures. Compared with traditional bolt-fixed or mechanically locked structures, this design allows for quick assembly and disassembly. The replacement time is reduced by approximately 70%, effectively reducing equipment downtime and significantly improving production efficiency. Traditional replacement of the punching cutter head 8 requires specialized technicians to use special tools and operate step by step in a specific sequence, which places high demands on the operator's skills. However, this design automates and mechanizes the disassembly and assembly process through the cooperation of the movable column 19 and the return spring 24. Operators only need to pull the movable column 19 to complete the disassembly and assembly without complex tools or professional skills. This improvement allows ordinary workers to complete the replacement of the punching cutter head 8, reducing reliance on highly skilled personnel and reducing labor costs.
