Description
Technical field
The present invention relates to sealing ring technical field of mold more particularly to a kind of modified sealing ring class molds.
Background technique
As shown in Figure 1, existing sealing ring class mold shares 3 punishment types, wherein inlay design using interference at 1, in addition 2
Place is designed using torn edges, to generate overlap at 2, rear road is needed manually to tear overlap, and current compression-molded structures, unit consumption are difficult essence
Really control, in order to which product does not lack material, actual volume of consumption per unit product is usually all much larger than theoretical unit consumption, thus causes the overlap of product very
The flash thickness of thickness, especially inner circle is greater than 0.15mm, and causing rear road to tear, overlap difficulty increases, efficiency reduces, product qualification rate
Decline；The face sealing used between upper mold and middle mould, upper mold and mold core, bearing area is big, and compressive load per unit area is just small, leads to rubber
Glue overlap is difficult to ironed；Clout slot is not designed, extra sizing material is had nowhere to go, is deposited at die joint, and rubber burrs are caused
It is blocked up；Lower die is mosaic texture, and two mold inserts are interference fits, and mold insert difficulty is dismantled, and mating surface is easily damaged in disassembly process,
It is unfavorable for maintenance, the maintenance in mold later period in this way；When product stripping, rubber product is wrapped in lower die, can not use using routine
Stripper apparatus, needs hand-stripping, and when hand ejection is just taken off one by one with biggish strength to be taken, and usual this kind of mold is a mould
25-36 chamber, the large labor intensity of such worker, the cost time is long, production efficiency is low.
Summary of the invention
Based on technical problem present in background technique, the invention proposes a kind of modified sealing ring class molds.
A kind of modified sealing ring class mold proposed by the present invention, upper mold, middle mould, lower die including structure in a ring and
Mold core, upper die and lower die arrange that mold core is arranged between upper mold and lower die and middle mould is arranged outside mold core, on the inside of middle mould up and down
Equipped with the land for being used to support mold core, middle mould top surface is equipped with first annular raised platform, and upper mold bottom surface outer is equipped with the second convex annular
Play platform；Under molding state, lower die top surface and middle mould bottom surface are against, first annular protrusion countertop and upper mold bottom surface against the
Second ring protrusion platform bottom surface and middle mould top surface against and the second annular protrusion platform medial surface support with first annular raised platform lateral surface
It leans on, mold core top surface and upper mold bottom surface are against mold core lateral surface and middle mould medial surface are against upper mold, first annular raised platform, mold core
Between shape forming cavity.
Preferably, core tip outer position is equipped with third annular protrusion platform, shape between third annular protrusion platform and upper mold
At the first clout slot.
Preferably, first annular raised platform outer position is equipped with the first depressed area being circular layout, the first depressed area with it is upper
The second clout slot is formed between mould.
Preferably, first annular raised platform medium position is equipped with the second depressed area being circular layout, the second depressed area with it is upper
The first torn edges slot is formed between mould.
Preferably, type chamber top position is located on mold core lateral surface and is equipped with the third depressed area being circular layout, third recess
The second torn edges slot is formed between area and upper mold.
Preferably, third depressed area top position is located on mold core lateral surface and is equipped with the 4th depressed area being circular layout, the
The first separating tank is formed between four depressed areas and upper mold.
Preferably, the second annular protrusion platform medial surface is equipped with the 5th depressed area being circular layout, the 5th depressed area and first
The second separating tank is formed between annular protrusion.
A kind of modified sealing ring class mold proposed by the present invention, reduces between upper mold and middle mould, upper mold and mold core
Sealing area changes big face and is sealed into facet sealing, i.e. linear sealing, with regard to big, rubber burrs are easy for ironed compressive load per unit area；On
Mould with middle mould, mold core parting at be respectively equipped with the first clout slot, the second clout slot, extra sizing material is squeezed the first clout
Slot, the second clout slot, the rubber burrs of die joint are easy for ironed；Upper mold with middle mould, mold core parting at be respectively equipped with
One separating tank, the second separating tank, when mold opens demoulding, overlap is moved with upper mold, and such overlap is separated with product；Lower die
It is 15 ° with mold core inclined-plane fit angle, mold core has the gap of 0.01-0.03mm in the state of not being pressurized, at parting, works as mold
The gap of 0.01-0.03mm is eliminated when production is pressurized, and is pressurized at parting inclined-plane, and the inclined-plane cooperation of compression is not easy to bore rubber burrs；
Upper mold first opens up when demoulding, and product stays between middle mould and mold core, and then lower die is opened downwards, solid outside vulcanizing press
Surely there is demoulding mechanism, mould is pushed out and is placed exactly in the top of demoulding mechanism in the middle, and at this moment middle mould moves still further below, demolding structure
Mandril will be ejected in mold core and product therefrom mould, worker need to will only pick up product, about 30 second time of this series of actions
Interior completion, the labor intensity of such worker reduces significantly, the time is spent to reduce, production efficiency improves；It is adopted between middle mould and mold core
It taking non-trimming to design, overlap will not be generated, overlap is controlled in 0-0.02mm at parting between upper mold and middle mould, upper mold and mold core,
The overlap of thickness can be separated with product automatically in demoulding in this way, and the overlap after separation is blown away with air gun, without again as changing
It needs special messenger to tear overlap like that into preceding, reduces rear road production process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of sealing ring class mold in the prior art；
Fig. 2 is a kind of structural schematic diagram of modified sealing ring class mold proposed by the present invention.
Specific embodiment
Referring to Fig. 2, the present invention proposes a kind of modified sealing ring class mold, upper mold 1, middle mould 2 including structure in a ring,
Lower die 3 and mold core 4.Upper mold 1, about 3 lower die arrange that mold core 4 is arranged between upper mold 1 and lower die 3 and middle mould 2 is arranged in mould
Outside core 4, the land 5 for being used to support mold core 4 is equipped on the inside of middle mould 2, middle 2 top surface of mould is equipped with first annular raised platform 6, upper mold 1
Bottom surface outer is equipped with the second annular protrusion platform 7.Under molding state, 3 top surface of lower die and middle 2 bottom surface of mould are against first annular convex
