[0027] like Figure 7 , 9 As shown, sealing rings 30 are provided between the stop plate 15 and the lower die 16 and between the lower die 16 and the lower die heating plate 17 .

[0028] like Figure 5As shown, an adjusting screw 18 is provided at the bottom position of the front end of the L-shaped frame 43, and the adjusting screw 18 is mounted on the fixing frame 1 through a nut. A rotation node is provided between the L-shaped frame 43 and the second connecting rod 10 and they are connected through the rotation node.

[0029] A gap corresponding to the thickness of the saddle leather surface is reserved between the leather pressing plate 14 and the stop plate 15 .

[0030] The leather pressing plate 14 is provided with a pin top avoidance space for the leather surface positioning pin 33 to pass through.

[0031] During use, the saddle bottom plate 38 is placed on the upper mold 13. After the saddle bottom plate 38 is placed, the saddle leather surface 37 is placed on the stop plate 15, and the upper and lower ends of the saddle leather surface 37 are fixed by the leather surface positioning pins 33. After the saddle leather surface 37 is placed, the first cylinder 4 pushes the first connecting plate 6 forward, further driving the leather pressing plate 14 to rotate downward and press on the stop plate 15. The anti-stub convex block on the leather pressing plate 14 will correspond to the anti-stub groove 31 on the stop plate 15 and press The saddle leather surface 37 is inserted into the anti-stub groove 31, thereby fixing the two sides of the front end of the saddle leather surface 37 and the two sides of the rear end of the saddle leather surface 37. After the leather pressing plate 14 is pressed downward on the stop plate 15, the pressure strip 19 is pushed upward by the third cylinder 8, so that the pressure strip 19 rotates with the rotating bracket 20 as the rotating fulcrum, so that the pressure strip 19 presses the fixed pressure block, thereby pressing the leather pressing plate 14 on the stop plate 15, so that the leather pressing plate 14 can press and fix the saddle leather surface 37, and then enter through the exhaust hole 28 on the lower mold heating plate 17. The lower mold 16 is evacuated to form a vacuum cavity between the lower mold 16 and the lower mold heating plate 17. The negative pressure suction hole 34 on the lower mold 16 will adsorb the saddle leather surface 37 to fit it on the lower mold 16. During this process, the circulating heating water pipe 27 in the lower mold heating plate 17 will heat the saddle leather surface 37 so that the saddle leather surface 37 can be softened so that it can better fit the lower mold 16. After the saddle leather surface 37 is fitted on the lower mold 16, the foam is injected into the saddle leather surface 37 by the injection molding machine, and then the fourth cylinder 9 is used to return. The retraction pulls the first connecting rod 10 forward to rotate, further pulls the second connecting rod 11 downward to rotate, and further drives the flip frame 2 to rotate downward, so that the upper mold 13 is close to the leather pressing plate 14. When the upper mold 13 reaches the position directly above the leather pressing plate 14, the downward pressure cylinder 3 will push the lower pressure plate 12 downward, further moving the upper mold 13 downward, thereby pressing the saddle bottom plate 38 onto the saddle leather surface 37, thereby forming the saddle bottom plate 38, the foam body 39 and the saddle leather surface 37 as one piece.

[0032] After the saddle bottom plate 38, foam body 39 and saddle leather surface 37 are integrally formed, the downward pressure cylinder 3 will drive the downward pressure plate 12 and the lower mold 13 to move upward and reset, and then push forward through the fourth cylinder 9, thereby driving the first connecting rod 10 to rotate backward and the second connecting rod 11 to rotate upward in turn, and further driving the flip frame 2 to rotate upward, so that the lower mold 13 is opened and away from the leather pressing plate 14, and then the first cylinder 4 pulls the first connecting plate 6 to drive the leather pressing plate 14 to rotate upward and open. After the leather pressing plate 14 is opened, the saddle leather surface 37 is removed from the leather surface positioning pin 33, and then the second cylinder 5 pulls the second connecting plate 7 to drive the stop plate 15 to rotate upward and open, and the formed flexible saddle is taken out from under the stop plate 15, thereby completing the production of the entire flexible saddle.

[0033] The setting of the adjusting screw 18 can adjust the upward tilt angle of the front end of the L-shaped frame 43 according to actual needs.

[0034] By plugging and installing the connecting guide column 22 and the connecting sleeve 21, the stopper plate 15 and the pressure plate 14 can be quickly disassembled and assembled.

[0035] The setting of the adjusting bolt 24 can adjust the exposed length of the connecting threaded column 42 according to actual use requirements, thereby adjusting the front and rear positions of the stop plate 15 and the leather pressing plate 14.

[0036] The positioning steel column 35 can be arranged to be positioned with the positioning circular hole 32 on the stop plate 15 when the lower mold 13 is pressed downward, thereby avoiding positional deviation when the lower mold 13 is pressed downward.

[0037] The arrangement of the flexible shock absorbing block 23 can provide a shock absorbing effect when the stop plate 15 and the skin pressing plate 14 rotate downward to cover.

[0038] The arrangement of the positioning jaws 26 can make the covering between the pressure plate 14 and the stop plate 15 and between the stop plate 15 and the lower die 16 more precise.

[0039] The beneficial effects of the present invention are: the structural design of the present invention is reasonable. First, the molds of the present invention are connected and installed with the frame by connecting guide pillars and connecting sleeves, which can facilitate simple and fast mold replacement and improve the use flexibility of the flexible saddle one-piece molding equipment; second, the use of circulating water heating and vacuum adsorption can make the saddle leather surface more fit to the lower mold after softening, thereby facilitating foaming injection; third, the setting of anti-stem protrusions and anti-stem grooves can prevent the appearance of stem wrinkles at the curved corners of the saddle leather surface when the saddle leather surface is vacuum adsorbed and fitted to the lower mold; fourth, the setting of positioning steel balls and positioning circular holes can facilitate the upper mold to position with the lower mold when pressing the installation base plate down on the lower mold, thereby improving the molding quality of the flexible saddle and preventing molding deviation.
