Description

Technical Field

[0001] The utility model relates to the field of tire vulcanizers, in particular to a temperature measuring and controlling device for a tire electric vulcanizing mold sleeve. Background Art

[0002] As we all know, the mold of the vulcanized tire usually uses the upper and lower hot plates with circulating steam to heat its upper and lower surfaces, and the mold sleeve on the side of the mold is provided with a steam cavity to pass steam to heat the mold pattern blocks. In order to save energy and reduce carbon emissions, many tire-related manufacturers have begun to explore electric vulcanization devices and processes. In addition to changing the upper and lower hot plates from steam heating to electric heating, the mold sleeve temperature measurement and control mostly adopts the method of setting electric heating plates and temperature sensors on the side of the mold. Due to the obstruction of the steam cavity inside the mold sleeve, this temperature measurement and control method shows a large deviation. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tire electric vulcanization mold sleeve temperature measurement and control device, which eliminates mold sleeve temperature measurement and control deviation and ensures tire vulcanization quality.

[0004] The utility model adopts the following technical solution to solve the technical problem: a temperature measuring and controlling device for a tire electric vulcanization mold sleeve, which is provided with a tire mold and is characterized in that a mold sleeve with an internal steam cavity is provided on the circumferential side of the tire mold, an electric heating plate is provided on the outer surface of the mold sleeve, a temperature sensor passes through the outer wall of the mold sleeve and the steam cavity, a detection end of the temperature sensor penetrates into the metal of the inner wall of the steam cavity, a wiring terminal of the temperature sensor is connected to the electric heating plate, the wiring of the temperature sensor and the wiring of the electric heating plate are connected to an electrical control cabinet after being merged, and a PLC controller of the electrical control cabinet controls the heating of the electric heating plate according to the measured value of the temperature sensor.

[0005] The beneficial effect of the utility model is that the temperature of the mold sleeve is measured by a temperature sensor inserted deep into the mold, which can achieve the same temperature measurement and control result as the steam heating method, eliminate the deviation of the mold sleeve temperature measurement and control, and ensure the tire vulcanization quality.
