Its main function is to fix the core mold on the fixed plate, install the valve and rubber pads on the core mold before vulcanization, and push the core mold fixed plate along the slideway through the rotation of the bearing to directly above the supporting heating plate. The outer dimensions of each core mold are exactly the same, and the inner dimensions (B and C) can be processed into different sizes according to different specifications of the valve. When using, use diagonal The 2 sets of vulcanization molds are sufficient, and the other 2 sets are reserved.1mm. The model column enters the valve hole to prevent the rubber from entering the valve inner hole during vulcanization. Pull the core mold fixing plate to the outer end to raise the mold opening fixing plate on the cylinder, and lift the valve 30~50mm.
Push the core mold fixing plate to the inner end (just below the upper template), the flat plunger rises, driving the supporting heating plate to rise, jacking up the core mold fixing plate, automatically positioning by the positioning device, and then pressing and vulcanizing. Since the length of the valve copper rod exceeds the thickness of the core mold fixing plate, the lower hot plate cannot directly rise to the core mold fixing plate. The vulcanization quality of the valve rubber pad has a greater impact on the quality of the finished inner tube.
The positioning Plastic Infusion Apparatus Parts Suppliers of this combined vulcanization mold are higher, and the other 2 sets can be used to reduce the positioning error. Because the valve cushion vulcanization mold needs to be moved between the hot plate of the flat vulcanizer and the operating table during vulcanization, the valve and cushion rubber are taken out individually.low. The composition and working principle of the combined vulcanization mold for the short-stem valve rubber cushion of this design are the same as those of the combined vulcanization mold for the long-stem valve rubber cushion, but the structure of individual parts is different. 1 The shortcomings of the original valve cushion vulcanization mold When the original single-hole,
4-hole or 6-hole vulcanization mold is in use, in order to give full play to the equipment performance and improve the vulcanization efficiency, generally multiple molds are vulcanized at the same time, that is, each valve Put the valve and the rubber cushion on the rubber cushion vulcanizing mold, and cover the upper molds and move them to the plate vulcanizing machine and press and vulcanize at the same time.
