Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold with a scraping function. Background Technology

[0002] In the field of stamping, stamping dies are a commonly used processing equipment. Traditional stamping dies typically consist of an upper die and a lower die, which perform cutting, punching, and forming of metal or non-metal materials through the relative movement of the upper and lower dies. For example, the utility model patent with application number CN202321249292.3 discloses an edge cutting mechanism composed of an upper die assembly and a lower die assembly. The upper die assembly has an upper cutting module, and the lower die assembly has a lower cutting module. The upper and lower cutting modules are staggered and cooperate to cut the edge material. However, in actual stamping processes, especially during cutting, scrap often adheres to the product edges. This is mainly because during the stamping and cutting process, after the material is subjected to strong shearing forces, there is a significant adhesion between the scrap and the product. This adhesion may originate from various factors such as intermolecular forces, electrostatic adsorption forces, and thermal effects generated during processing. Traditional stamping dies lack an effective scrap removal mechanism. In actual production, operators usually need to manually clean the waste material adhering to the product or inside the mold after each stamping. Utility Model Content

[0003] The purpose of this invention is to provide a mold with a scraping function to solve the technical problem of the lack of an effective waste removal mechanism in the existing technology.

[0004] To achieve the above objectives, embodiments of this utility model provide a mold with a scraping function, including an upper mold, a lower mold, and a scraper. The lower mold and the upper mold are fitted together along a first direction. The scraper is movably connected to the side of the upper mold facing the lower mold, and the scraper can move between an initial position and a clearance position. When the upper mold moves towards the lower mold along the first direction, the scraper can abut against the side of the scrap facing the upper mold, so that the scraper moves to the clearance position and avoids the scrap. When the scraper detaches from the scrap, the scraper can move back to the initial position under its own weight or under the action of a reset member. When the scraper is in the initial position and below the scrap, the upper mold can move away from the lower mold along the first direction, so that the scraper can abut against the side of the scrap away from the upper mold.

[0005] Preferably, the upper mold is fixedly connected to a connecting rod, and the end of the connecting rod away from the upper mold is rotatably connected to the scraper. The scraper can rotate on the connecting rod to move between an initial position and a clearance position.

[0006] Preferably, the end of the connecting rod away from the upper mold is provided with a clearance groove, and one end of the scraper and the end of the clearance groove away from the upper mold are rotatably connected. When the scraper rotates to the clearance position, the scraper part is partially built into the clearance groove; when the scraper rotates to the initial position, the side wall of the scraper and the end face of the clearance groove abut against each other.

[0007] Preferably, a rotating shaft is inserted at the end of the connecting rod away from the upper mold, the rotating shaft passes through the clearance groove, and one end of the scraper is rotatably connected to the rotating shaft.

[0008] Preferably, the end of the clearance groove near the upper mold can abut against the side wall of the scraper, so that the scraper forms an angle with the vertical direction.

[0009] Preferably, the lower mold is provided with a discharge groove, the scraper is located above the discharge groove, and the discharge groove is located below the waste material.

[0010] Preferably, the bottom surface of the discharge trough is inclined downward from the inside of the lower mold toward the outside of the lower mold.

[0018] Reference Figures 1 to 2 This utility model provides a mold with a scraping function, including an upper mold 100, a lower mold 200, and a scraper 300. The lower mold 200 and the upper mold 100 are fitted together along a first direction. The scraper 300 is movably connected to the side of the upper mold 100 facing the lower mold 200, and the scraper 300 can move between an initial position and a clearance position. When the upper mold 100 moves towards the lower mold 200 along the first direction, the scraper 300 can scrape the waste material. 1. The scraper 300 abuts against the side of the upper mold 100 so that it moves to a clearance position and avoids the waste 1. When the scraper 300 is separated from the waste 1, it can move to the initial position under its own weight or under the action of the reset member. When the scraper 300 is in the initial position and below the waste 1, the upper mold 100 can move away from the lower mold 200 along the first direction so that the scraper 300 can abut against the side of the waste 1 away from the upper mold 100.

[0019] Reference Figure 1 In the first direction ( Figure 1 In the reciprocating direction indicated by the arrow, the upper mold 100 and the lower mold 200 can move away from or towards each other. Therefore, refer to... Figures 1 to 4 In actual operation of the embodiments of this utility model, the following working steps are included: Step 1. The upper mold 100 and the lower mold 200 move along the first direction (in this embodiment, ...) Figure 1 The mold closing action is performed in the vertical direction. Step 2. When the mold is closed, the scraper 300 contacts the upper surface of the waste material 1 and is pushed to the clearance position, so that the scraper 300 can move along the first direction to below the waste material 1; Step 3. The scraper 300 begins to reset under its own weight or the action of the reset component; Step 4. After stamping is completed, the upper die 100 begins to move away from the lower die 200; Step 5. The scraper 300 moves with the upper mold 100 and comes into contact with the lower surface of the waste material 1, generating a scraping force. The scraping force causes the waste material 1 to separate from the product and fall off.

[0020] In summary, after the upper mold 100 and the lower mold 200 cut the product, the scraper 300 scrapes the waste material 1 from below, causing the waste material 1 to fall off, preventing the waste material 1 from sticking to the product and improving processing efficiency.

[0021] In some embodiments, refer to Figure 1 and Figure 2 The upper mold 100 is fixedly connected to a connecting rod 110. The end of the connecting rod 110 away from the upper mold 100 is rotatably connected to the scraper 300. The scraper 300 can rotate on the connecting rod 110 to move between an initial position and a clearance position. The connecting rod 110 is fixed to the upper mold 100 as an intermediate connecting member. When the scraper 300 is subjected to an external force, it can rotate around a fixed rotation axis. The rotational movement causes the scraper 300 to switch between the initial position and the clearance position.

[0022] In some embodiments, refer to Figure 2 A rotating shaft 112 is inserted into the end of the connecting rod 110 furthest from the upper mold 100. The rotating shaft 112 passes through the clearance groove 111, and one end of the scraper 300 is rotatably connected to the rotating shaft 112. The rotating shaft 112 serves as the rotation axis of the scraper 300, allowing the scraper 300 to rotate freely around the rotating shaft 112. The scraper 300 is a long, strip-shaped rod. One end of the scraper 300 is connected to the rotating shaft 112, and the other end serves as the working end, contacting the waste material 1 to ensure full contact with the waste material 1 and improve the scraping effect.

[0023] Preferably, referring to Figure 2The connecting rod 110 has a clearance groove 111 at the end away from the upper mold 100. One end of the scraper 300 is rotatably connected to the end of the clearance groove 111 away from the upper mold 100. When the scraper 300 rotates to the clearance position, part of the scraper 300 is housed in the clearance groove 111. When the scraper 300 rotates to the initial position, the side wall of the scraper 300 abuts against the end face of the clearance groove 111. When the scraper 300 rotates to the clearance position, part of the structure enters the clearance groove 111, which provides storage space for the scraper 300. On the other hand, the end face of the clearance groove 111 restricts the rotation range of the scraper 300, ensuring that the scraper 300 is accurately positioned in the initial position.

[0024] As a further optimization of the above embodiments, refer to Figure 2 The end of the clearance groove 111 near the upper mold 100 can abut against the side wall of the scraper 300, so that the scraper 300 forms an angle with the vertical direction. When the end of the clearance groove 111 near the upper mold 100 abuts against the side wall of the scraper 300, the scraper 300 is in the clearance position. The angled position allows the scraper 300 to return to its initial position under the action of gravity after it is removed from the waste material 1, which is convenient for use.

[0025] In other embodiments, a reset member is provided between the scraper 300 and the connecting rod 110. The reset member is an elastic component such as a spring, which uses the elasticity of the spring to drive the scraper 300 to swing toward the initial position.

[0026] In some embodiments, referring to FIG1, the lower mold 200 is provided with a discharge groove 210, and the scraper 300 is located above the discharge groove 210. The lower mold 200 is designed with a dedicated discharge groove 210, and the scraper 300 is located above the discharge groove 210. The scraped waste material 1 falls directly into the discharge groove 210 below. The discharge groove 210 guides the waste material 1 to be discharged outside the mold, realizing the orderly collection and discharge of the waste material 1, preventing the waste material 1 from accumulating in the mold, and facilitating the subsequent waste material 1 processing.

[0027] Preferably, refer to Figure 1 The bottom surface of the discharge trough 210 is inclined downward from the inside of the lower mold 200 toward the outside of the lower mold 200. After the waste material 1 falls into the discharge trough 210, it slides automatically under the action of gravity and the inclined surface, preventing the waste material 1 from blocking in the discharge trough 210 and ensuring that the waste material 1 is completely discharged from the mold.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
