Abstract

This invention provides a pad molding mold which can ensure a necessary bonding area between a rubber material of a pressing pad (26) and a wire (24) and can prevent the occurrence of waving and bending of a wire (24) after molding. In a two-split mold for molding a pressing pad (26) having a pressing face (22) for pressing the outer peripheral surface of a fixing roller (16), a holding groove (42) for providing a wire (24) attached along one side of the pressing face (22) is provided in one split mold (29a) in the two-split mold. A plurality of protrusions (46) for pressing the outer surfaceof the wire (24) is intermittently provided in the longitudinal direction in the other split mold (29b), in the two-split mold, at its site opposed to the holding groove (42). The fixing roller (16) includes a pressing roller, and the pressing pad (26) includes a fixing pad.

Description

technical field [0001] The present invention relates to a pad molding die and a pad used for molding pads such as pressure pads and fixing pads used in fixing devices such as electronic copiers. Background technique [0002] In the past, for example, if Figure 9 As shown, in a fixing device 10 such as an electronic copier, the endless belt 14 pressed against the back by the pressure pad 12 is brought into pressure contact with the fixing roller 16, and the toner on the recording paper passing through the fixing area as the pressing area is brought into contact with each other. Agent fixing is well known (for example, refer to Patent Document 1). [0003] Figure 9 The shown fixing device 10 has a fixing roller 16 and an endless belt 14 in pressure contact therewith. The endless belt 14 is rotatably supported by a drive roller 15a, a driven roller 15b, and a tension roller 15c. Inside the endless belt 14, a pressure pad 12 formed of an elastic rubber material such as silic...
