Description

Technical Field

[0001] The utility model relates to the technical field related to hardware mold processing, in particular to a side punching structure of a hardware mold. Background Art

[0002] Metal molds are used in industrial production to make parts or products of the required shape from metal materials using various presses and special tools installed on the presses. Such special tools are collectively called metal molds.

[0003] When processing a hardware mold, it is necessary to perform a punching operation on it. However, when performing punching processing, the existing hardware molds on the market generally drive the punching head to punch the hardware mold. For example, when a cover-shaped hardware mold is punched in the above manner, the punching is generally performed from the outside of the hardware mold to the inside. Normally, after punching, the burr surface is located inside the cover-shaped hardware mold, which is not convenient for later grinding operations, thereby reducing the practicality of the device.

[0004] Therefore, for structural products with special requirements, it is required to punch from the side, and the burr surface must be on the outside of the cutting process structure. The present invention provides a hardware mold side punching structure. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a side punching structure for a hardware mold, which solves the problems mentioned in the background technology.

An electric push cylinder is installed between the upper template and the base plate. The bottom of the cylinder body of the electric push cylinder is fixedly connected to the base plate, and the telescopic end of the electric push cylinder is fixedly connected to the extension block.

[0011] Further, the punching and cutting matching assembly includes a fixed block and a matching through slot, the fixed block is fixedly connected to the lower template, the matching through slot is arranged on the cavity plate, the fixed block is located in the matching through slot, one side of the fixed block is matched with a matching block, one side of the matching block is fixed with two punching and cutting heads, and one end of each punching and cutting head away from the matching block penetrates the mold to be processed and is inserted into the fixed connecting plate;

[0012] Two limiting holes are connected to one side of the matching through slot, each of the limiting holes is opened on the cavity plate, and a matching rod is inserted in each of the limiting holes, one end of each matching rod is fixedly connected to the matching block, and a matching spring is arranged between the two matching rods, and the two ends of the matching spring are respectively fixedly connected to the matching block and the matching through slot.

[0017] 1. The utility model starts the electric push cylinder by setting the lifting and matching components, driving the extension block, the upper template, and the matching pressure block to rise and fall synchronously, so as to drive the matching pressure block to press on the top surface of the mold to be processed to fix it, and facilitate the side punching operation at a later stage;

[0018] 2. When the upper template of the utility model continues to descend, the cavity plate will also descend synchronously, causing the reset spring to be compressed. At this time, since the oblique cut surface will slide along the matching cut surface, each matching rod will be driven to slide along the corresponding limit socket, thereby compressing the matching spring, thereby facilitating the punching head to punch holes from the inside of the mold to be processed to the outside, not only completing the punching operation, but also this punching method can make the burr surface after punching located on the outside of the mold to be processed, which is convenient for later grinding processing.
