Embodiment 1

[0038] A kind of automatic mold opening mold structure of conical rubber spring vulcanization mold, such as figure 1 with figure 2 As shown, the mold structure of the entire vulcanization mold includes an upper mold 1, an injection cylinder 2, an injection insert 3, a middle mold 4, a flap mold 5, a lower mold 6, and a bottom mold 7 from top to bottom. The lower plate 8 and the upper mold 1 fixed to the vulcanization equipment are fixed to the upper plate 82 of the vulcanization equipment to fix the entire mold to the vulcanization equipment. When vulcanizing and closing the mold, the upper mold 1 injects the rubber in the injection cylinder 2 through the injection insert. 3. The flow channel is injected into the product cavity surrounded by the middle mold 4, the valve mold 5 and the lower mold 6 to form a vulcanized product of conical rubber spring; the valve mold 5 is divided into two symmetrical pieces, and the mold is opened after vulcanization. The flap mold 5 can be s...

Embodiment 2

[0043] This embodiment is basically the same as the above-mentioned embodiment, the difference is: in this embodiment: as Figure 15 As shown, two bead 64 is provided with U-shaped groove 65 on the side close to valve mold 5, and at this moment, the flange 52 of valve mold 5 is convex at the side wall place of valve mold 5, no longer the same as in embodiment one. Likewise, the bottom of the flange 52 is flush with the bottom of the valve mold 5 .

Embodiment 3

[0045] This embodiment is basically the same as the above embodiment, except that in this embodiment, the slot 71 on the bottom mold 7 can also be arranged on the bottom surface, but this structure is not as convenient as the first embodiment for alignment and positioning.

[0046] It can be seen from the above-mentioned embodiments that the present invention also relates to a fully automatic mold opening method for a conical rubber spring vulcanization mold, in which the glue injection insert 3 of the vulcanization mold is fixed on the middle mold 4 of the mold and moves up and down together with the middle mold 4 In this way, the automatic separation between the mold injection insert 3, the injection cylinder 2 and the vulcanized product is completed, and the automatic operation of the injection insert 3 is realized; the middle mold 4, the flap mold 5 and the lower mold 6 of the vulcanization mold are used. The way of setting the guide mechanism between them makes the valve m...

Abstract

The invention discloses a method and mold structure for the conical rubber spring vulcanization mold full-automatic mold opening. A mode that a glue injection insert of a vulcanization mold is fixed to a middle mold of a mold and moves up and down along with the middle mold is adopted, automatic separation between a mold glue injection barrel and a vulcanization product is completed, automatic operation of the glue injection insert is achieved, and a mode that a guide mechanism is arranged among the middle mold, petal molds and a lower mold of the vulcanization mold, so that the petal molds move up and down along with the middle mold to finish separation and closing between the two petal molds, automatic separation between the petal molds and a vulcanized product is realized, the vulcanized product is automatically ejected in a manner of arranging an ejection mechanism on the lower mold of the vulcanization mold, and a mode that a positioning mechanism is arranged between a bottom moldof the vulcanization mold and a lower flat plate of vulcanization equipment to realize quick positioning between the vulcanization mold and the vulcanization equipment. According to the method and mold structure for the conical rubber spring vulcanization mold full-automatic mold opening, full-automatic separation among mold parts and between the mold parts and the vulcanized product is achieved,and high-difficulty semi-automatic operation and structure of using a crane back and forth at present are avoided.

Description

technical field [0001] The invention relates to a mold opening method and a mold structure, in particular to an automatic mold opening method and a mold structure for a conical rubber spring vulcanization mold. Background technique [0002] Railway conical rubber spring products are composed of a mandrel, a spacer, rubber and a jacket. It is installed between the bogie and the wheel set of a railway passenger car. It is a key component for vibration reduction, noise reduction and safe operation of passenger cars. As an important part of the product production, the vulcanization mold for conical rubber spring products is a key determinant of product quality. At present, most of the conical rubber spring vulcanization molds are manual or semi-automatic. Difficulty in mold operation and low operation efficiency in vulcanization production , short mold life, frequent product quality problems and many other defects, there is a big gap with the goal of lean production. [0003] F...
