Abstract

The invention discloses thermoforming die in-mold punching equipment with heating devices, and aims to provide the heating devices which are used for heating the periphery of a punching hole to a certain temperature when the temperature is too low in the production process during punching in a thermoforming die, so that a punch is not prone to breaking during punching. The in-mold punching equipment is characterized in that female die linings and a supporting seat are provided with the heating devices; each heating device comprises a heating rod, a temperature sensor and a heating control system; the heating rods and the temperature sensors are connected with the heating control systems; and the heating rods penetrate through the supporting seat and extend into the female die linings. According the in-mold punching equipment, the heating rods and the temperature sensors are arranged on the female die linings, so that the temperature of the female die linings and a pressing plate is detected through the temperature sensors at any time; and when the temperature is lower than a certain value, the heating control systems control the heating rods to increase the temperature to make thewhole female die linings and the pressing plate stabilized at a stable temperature, so that a part is not cooled too quickly when making contact with the female die linings, thus the strength of the part is not increased too quickly, and the punch is not prone to breaking during punching.
