[0020] Please refer to Figs. 1-3 The present application provides a kind of convenient operation's rubber roller production with the technical scheme of pressing mould: a kind of convenient operation's rubber roller production with pressing mould, comprising: base 1, lower mould 2 is fixedly installed on base 1, upper mould 3 is cooperatively arranged on the upper end of lower mould 2, connecting strip 4 is fixed on the both sides of upper mould 3, guide frame 5 is fixed on base 1, guide frame 5 penetrates the connecting strip 4 on both sides, first electric telescopic rod 6 is fixed on guide frame 5, and the output end of first electric telescopic rod 6 is fixedly connected with upper mould 3. Lower mould 2 and upper mould 3 are provided with blocking piece 7 on both sides, second electric telescopic rod 8 is fixed on base 1, the output end of second electric telescopic rod 8 is fixedly connected with the blocking piece 7 on one side, catheter 9 is penetrated on the blocking piece 7 on the other side, communication pipe 10 is fixedly installed on the upper end of catheter 9 and is communicated, sleeve 11 is fixed on base 1, one end of communication pipe 10 is inserted into sleeve 11 and is communicated, external delivery pump is communicated with sleeve 11 and material is guided into sleeve 11, sealing rod 12 is inserted in one end of catheter 9, and sealing rod 12 is used to block catheter 9.

[0021] The material is introduced into the sleeve 11 by an external delivery pump, and the material enters the guide pipe 9 through the communication pipe 10, so that the material enters the mold cavity formed by the lower mold 2, the upper mold 3 and the two sealing members 7. The end of the guide pipe 9 is sealed by the sealing rod 12. After the material injection is completed, the end of the sealing rod 12 is completely inserted into the guide pipe 9, and the lower end of the communication pipe 10 is sealed by the sealing rod 12. The material cannot enter the guide pipe 9, so that the rubber roller is more flush and beautiful towards the end face of the sealing rod 12. The protruding part on one side of the rubber roller does not need to be cut off, which saves time and improves work efficiency.

[0022] The sealing rod 12 is fixed with an annular piece 13. The slide 14 is fixed on the machine base 1, and the slide groove inside the slide 14 is a cross-shaped slide groove. The movable seat 15 is fixed on the guide pipe 9, and the lower end of the movable seat 15 is slidably arranged in the slide 14. The sealing rod 12 is provided with two spaced limiting holes 16, and the first limiting rod 17 is arranged at the limiting hole 16.
