Description

Technical Field

[0001] The utility model belongs to the technical field of mold protection, and in particular relates to a safety protection structure for a mold. Background Art

[0002] Stamping processing is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet metal to deformation force in the mold and deform it, so as to obtain product parts of a certain shape, size and performance. The continuous stamping die is a more advanced die form. In the production process of the continuous stamping die, various faults may occur that cause the strip material to not be delivered in place. At this time, the punch press is required to stop automatically during the pressing process to protect the stamping die. At this time, a safety protection structure is needed.

[0003] The current protection structures on the market have the following problems when applied: When applying the traditional safety protection structure, a detection pin plus a lateral sensing switch structure is used. When the material strip under the detection pin deviates from the correct position, the hole on the material strip deviates from the correct position. When the mold moves downward, the detection pin is blocked by the material strip and compressed upward to drive the micro switch to operate. The signal is transmitted to the punch press to stop the machine. However, the traditional structure is large in size and needs to be installed on the upper die base, from the upper die base to the unloading plate. It is not easy to achieve standardization and is inconvenient to use. Utility Model Content

[0029] The working principle of the safety protection structure for the mold: when applying the safety protection device, first install the cover plate 3 to the surface of the main body block 1 to prevent impurities from entering the safety protection structure, so that the protection structure is stuck, and then insert the insertion rod 7 into the required position to fix the entire safety protection structure. When the material belt under the detection pin 10 deviates from the correct position, the hole on the material belt deviates from the correct position. When the mold moves downward, it drives the first spring 11 to move, and the detection pin 10 is blocked by the material belt and compressed upward to drive the micro switch 4 to operate. The signal is transmitted to the punch press to stop the machine. The compact die safety protection structure is easy to install, thereby reducing the production cost and use cost of the device, and can better standardize production and make it more convenient to use.
