Embodiment 1

[0038] A fully automatic mold opening mold structure of a conical rubber spring vulcanization mold, such as figure 1 and figure 2 As shown, the mold structure of the entire vulcanization mold includes, from top to bottom, an upper mold 1, a plastic injection cylinder 2, a plastic injection insert 3, a middle mold 4, a flap mold 5, a lower mold 6, and a bottom mold 7. Through the bottom mold 7 The lower plate 8 fixed to the vulcanization equipment and the upper mold 1 are fixed to the upper plate 82 of the vulcanization equipment to fix the entire mold to the vulcanization equipment. 3. The flow channel is injected into the product cavity enclosed by the middle mold 4, the flap mold 5 and the lower mold 6 to form a vulcanized product of a conical rubber spring; the flap mold 5 is divided into two symmetrical pieces, and the mold is opened after vulcanization molding. The half mold 5 can be separated to separate from the vulcanized product. like image 3 As shown in the figu...

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, the two pressing bars 64 are provided with U-shaped grooves 65 on the sides close to the flap mold 5. At this time, the convex edge 52 of the flap mold 5 is convex at the side wall of the flap mold 5, which is no longer the same as in the first embodiment. Likewise, the bottom of the lip 52 is flush with the bottom of the half mold 5 .

Embodiment 3

[0045] This embodiment is basically the same as the above-mentioned 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 for alignment and positioning as in the first embodiment.

[0046] It can be seen from the above embodiments that the present invention also relates to a fully automatic mold opening method for a conical rubber spring vulcanization mold. In this way, the automatic separation between the mold injection insert 3, the plastic injection cylinder 2 and the vulcanized product is completed, and the automatic operation of the injection insert 3 is realized; The way of setting up a guiding mechanism between them makes the flap mold 5 complete the separation and closing between the two flap molds 5 with the up and down movement of the middle mold 4, and realizes the automatic separation between the flap mold 5 and the vulcanized product; the lower mold of the vu...

Abstract

A fully automatic mold opening method and mold structure for a conical rubber spring vulcanization mold. The rubber injection insert of the vulcanization mold is fixed on the middle mold of the mold and moves up and down together with the middle mold to complete the connection between the mold rubber injection cylinder and the vulcanized product. The automatic separation between the molds realizes the automatic operation of the injection inserts; the guide mechanism is set between the middle mold, the valve mold and the lower mold of the vulcanization mold so that the valve mold moves up and down with the middle mold to complete the gap between the two valve molds. The separation and closing of the vulcanization mold can realize the automatic separation between the valve mold and the vulcanized product; the vulcanized product is automatically ejected by setting an ejection mechanism on the lower mold of the vulcanization mold; the bottom mold of the vulcanization mold and the lower plate of the curing equipment The fast positioning between the vulcanization mold and the vulcanization equipment is realized by setting a positioning mechanism between them. The invention realizes the automatic separation between the mold parts and between the mold parts and the vulcanized product, and avoids the highly difficult semi-automatic operation and structure of using the mobile crane back and forth.

Description

technical field [0001] The invention relates to a mold opening method and mold structure, in particular to a fully automatic mold opening method and mold structure of a conical rubber spring vulcanization mold. Background technique [0002] The railway conical rubber spring product is composed of a mandrel, a spacer, a rubber and a jacket. It is installed between the railway passenger car bogie and the wheelset, and is a key component for vibration reduction, noise reduction and safe operation of the passenger car. The vulcanization mold of conical rubber spring products is an important part of the production of this product, and it is a key determinant of the quality of the product. At present, the vulcanization molds of conical rubber springs are mostly manual or semi-automatic mold structures, and the vulcanization production has difficulty in mold operation and low operation efficiency. , short mold life, frequent product quality problems and many other defects, there is...
