According to the utility model, manpower resources and efficiency can be saved, secondary turning for cutting off the runner remaining at the top of a valve oil seal is not needed, and a spigot is machined on the mold so as to break the runner part together with flying skins at a material cavity during opening the mold, so that the valve oil seal product is directly obtained.
Description
Technical field
The utility model relates to a kind of from pulling apart die for valve oil seal, relates in particular to a kind of head valve oil sealing pressure injection mold for engine.
Background technology
Valve oil seal is one of strength member of engine valve group, and footpath oral area dress self-tightening spring or steel wire are used for the sealing of engine valve guide rod, are a kind of of oil sealing.At high temperature contact with gasoline and machine oil, therefore need to adopt heat resistance and the good material of oil resistivity, generally formed by outer skeleton and the common sulfuration of fluorubber, although can satisfy the technological requirement of valve oil seal sulfuration, valve oil seal can prevent that machine oil from entering air inlet-outlet pipe and the machine oil that causes runs off, the mist and the discharging waste gas that prevent gasoline and air are leaked, and prevent that engine motor oil from entering the combustion chamber.
At present, traditional die for valve oil seal all is that 4RT annotates laminated structure, as shown in Figure 1, comprise mould 1-3, original mould push pedal 1-4 and original mould counterdie 1-5 in original mould material feeding plug 1-1, original mould patrix 1-2, the original mould, when product is got in the mould die sinking, as shown in Figure 2, the mould separation flies skin and product, utilizes turning processing secondary separation redundance and product.This kind mould molding valve oil seal out, after die sinking, the top chamber place flies skin and valve oil seal automatic disconnection, and then by just obtaining the valve oil seal product after lathe turning processing the runner excision that the valve oil seal top is residual, lathe processing needs other procedure, affects the production efficiency of whole oil sealing processing.
The utility model content
The purpose of this utility model is: a kind of oil-tight mould that secondary turning processing just can be pulled apart valve oil seal certainly that need not is provided, solve existing oil-tight mould and need secondary turning processing, cause waste of manpower, affect the technical problem of production efficiency, thereby can effectively solve above-mentioned problems of the prior art.
The purpose of this utility model is to realize by following technical proposals: a kind of from pulling apart die for valve oil seal, comprise material feeding plug, patrix, middle mould, push pedal and the counterdie installed successively from top to bottom, material feeding plug and patrix cooperatively interact, and patrix and middle mould cooperatively interact, and middle mould matches with counterdie; The middle part of described patrix is provided with die cavity, glue groove and through hole, the bottom of middle mould is provided with lower slotted eye, when patrix cooperates with middle mould, through hole and the corresponding connection of lower slotted eye, described push pedal and the clamping of lower slotted eye part, the top of counterdie is provided with the protrusion core corresponding with die cavity, when the protrusion core places in the lower slotted eye, the top boss that protrudes core cooperates with the bottom surface of through hole, forms band and pulls apart the runner of structure.
As preferably, material feeding plug bottom is protruded the position and is cooperatively interacted with recessed position, patrix top, and the recessed position that position and middle mould top are protruded in the patrix bottom cooperatively interacts, and matches with the protrusion position of counterdie in the recessed position bottom the middle mould.
As preferably, the recessed position of described glue groove and patrix top is fixed, and through hole is connected with middle part, recessed position, patrix top.
In the utility model, the effect of part parts is as follows:
1. protrusion position, material feeding plug bottom and the recessed position of patrix are matching relationship, play the guide-localization effect, Main Function is when preformed sizing material is put into the recessed position of patrix, and the protrusion position by the material feeding plug is pressed into recessed position, plays the effect that sizing material is pressed into runner.
2. the protrusion position of patrix and middle mould and recessed position are matching relationship, play the guide-localization effect, and middle mould is mainly played a supporting role, and the effect of intermediate throughholes is the location on mould for valve oil seal and metallic framework.
3. push pedal is that effect is for the valve oil seal product can easily be taken off from counterdie after sulfuration, the push pedal design is in the lower slotted eye of middle mould, protruding the position with counterdie matches, move upward by opening prizing of die cavity, thereby valve oil seal is together moved upward, and then come off from counterdie.
4. the protrusion position of middle mould and counterdie and recessed position are matching relationship, play the guide-localization effect.
5. glue groove: the purpose of design glue groove is to make the runner can be smoothly from pulling apart, because if do not design the glue groove, fly in the thinner situation of skin runner section and flying skin flies skin distortion when die sinking after, to together be pulled patrix with product with runner, and can not be produced a desired effect.And after having designed the glue groove, be connected firm connection with runner by the glue groove, and when die sinking, can be fixed on smoothly the top groove place of patrix, runner is pulled apart from default.
6. through hole: the through hole of patrix is the Outboard Sections of runner, the inside part of runner is by the top core top moulding of bed die, bed die top core upper design has boss, variation by diameter, cooperate the runner that forms thick on top with the patrix through hole, the bottom predeterminated position designs attenuation by boss, therefore when die sinking, runner section will be torn in the thinnest fragile part, produces a desired effect.
Compared with prior art, the beneficial effects of the utility model: the utility model can be saved human resources and efficient from pulling apart die for valve oil seal in production valve oil seal process, this oil-tight mould need not secondary turning processing, just can excise the residual runner section in valve oil seal top, at mould processing seam runner section is flown skin together with place, material chamber during by die sinking and pull apart from stop portion, directly obtain the valve oil seal product.
