Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of mould for the production of foaming part.
Background technology
Foaming part is one of major product of vehicle body use, current foaming piece is in foaming process, leak the FAQs that material is foaming mould, also be cause a major reason of producing the waste of this type of cost of parts, the main cause of leaking material is that the cooperation of upper/lower die die joint place is not in place, be combined with caused by the reason of gap, but current parting surface structure (plane contact type sealing) realizes the individual really technological difficulties sealed completely, or the cost price accomplished is quite high, and this plane contact type die joint rapid wear, need often to safeguard, frequent maintenance also affects rhythm of production, use cost is higher.
Chinese patent CN102069556A discloses low ratio foamed injecting molding die, it is made up of parts such as locating piece, lower bolster, push rod, backing plate, locating piece, combined heave die, core, sprue bush, combined die, solid plates, the mold work principle of this mechanism is identical with normal injection mould, it is applicable to various plastics, apply extremely extensive, mold materials can with aluminium alloy or kirsite, but it does not still solve the problem of Lou material.
Utility model content
The purpose of this utility model is exactly provide a kind of part non-trimming reducing mould development cost, production to overcome defect that above-mentioned prior art exists, material can not be leaked, do not need edge process for the production of the mould of part of foaming.
The purpose of this utility model can be achieved through the following technical solutions:
For the production of a mould for foaming part, comprising:
The upper cores of the upper baffle plate lower surface of upper baffle plate, setting,
Lower mould bottom plate, be arranged on the lower die of lower mould bottom plate upper surface,
The surrounding of upper baffle plate and lower mould bottom plate is provided with guide-localization post, makes foaming forming parts after upper cores and lower die matched moulds,
The joint face of described upper cores and lower die is taper seam die joint, and upper cores is provided with the skewed boss protruded downwards at joint face place, lower die is provided with the inclined-plane matched with boss at joint face place.
In described taper seam die joint, the angle of inclined-plane and level is 45-60 °.
Taper seam die joint is the die joint through hardened artiwear process, and hardened artiwear process adopts following steps:
1, taper seam die joint place temper, release stress;
2, taper seam die joint place's laser quenching, hardness process is to 50Hrc.
Described upper cores and lower die offer cooling water pipe interface.
Described upper baffle plate offers foaming charging aperture and vacuum suction hole.
Compared with prior art, the utility model is innovated in the die joint place structure of mould, distinct effect is brought to production, the die joint mould of this case structure, good sealing effect, without running material (flash), non-trimming, product periphery is neat, clean and tidy, save material, low-carbon environment-friendly, adopts taper seam somatotype contact surface, the strict angle angle controlling inclined-plane and level in die joint, make mould under the effect of the pressure, be more prone to sealing, and then make die joint better tightness, have the following advantages:
One, reduce mould development cost, shorten mold developing cycle, reduce the production cost of part, this type of part is produced towards low energy consumption, low-carbon (LC), environmental protection future development.
Two, the part non-trimming produced, does not need edge process, reduces shopwork labour intensity, alleviates employee work dynamics.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is the close-up schematic view at die joint place in Fig. 1;
Fig. 3 is plan structure schematic diagram of the present utility model;
Fig. 4 is structural representation of the present utility model.
In figure, 1 be upper baffle plate, 2 be upper cores, 3 be lower mould bottom plate, 4 be lower die, 5 be cooling water pipe interface, 6 be vacuum suction hole, 7 be guide-localization post, 8 for foaming charging aperture, 9 is for taper seam die joint.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of mould for the production of foaming part, its structure as Figure 1-4, comprise: upper baffle plate 1, the upper cores 2 of upper baffle plate 1 lower surface arranged, lower mould bottom plate 3, be arranged on the lower die 4 of lower mould bottom plate 3 upper surface, upper cores 3 and lower die 4 make foaming forming parts after matched moulds, upper baffle plate 1 is provided with guide-localization post 7 pairs of moulds with the surrounding of lower mould bottom plate 3 and positions, upper cores 2 and lower die 4 offer cooling water pipe interface 5 and for connecting cooling water, cooling and shaping is carried out to formed in mould product, upper baffle plate 1 offers foaming charging aperture 8 and vacuum suction hole 6.
Be with the difference of prior art, the joint face of upper cores 2 and lower die 4 is taper seam die joint 9, wherein, upper cores 2 is provided with the skewed boss protruded downwards at joint face place, lower die 4 is provided with the inclined-plane matched with boss at joint face place, the angle of inclined-plane and level is 45-60 °, the angle that the present embodiment adopts is 45 °, adopt this angle can make mould under the effect of the pressure, be more prone to sealing, and then make die joint better tightness.In addition, taper seam die joint 9 place carries out hardened artiwear process, adopts following steps:
1, taper seam die joint place temper, release stress;
2, taper seam die joint place's laser quenching, hardness process is to 50Hrc.
By above-mentioned process, make mould good sealing effect, without running material (flash), non-trimming, product periphery is neat, clean and tidy, saves material.
