Description
Technical field
The utility model is related to technical field of mold, and in particular to a kind of high-light no-trace injection-die parting surface structure.
Background technology
Injection mold is made up of upper die and lower die two parts, the part that both can contact in closed state referred to as parting
Face.The design of die joint directly affects the complexity of plastic part quality, mould structure portion and operation, is the pass of mold design success or failure
One of key factor.It is required that the smooth smooth-going of die joint, can be brought into close contact, and special requirement mold cavity can not have hot melt plastic
Expect gas, otherwise plastic easily produces overlap at die joint.When being commonly designed, in addition to cavity positions, upper die and lower die
Entire surface is in contact, and so increases the grinding work of mold parting surface, lengthens die manufacturing cycle, particularly with big or middle
Pattern has, it is desirable to which it is extremely difficult to ensure that whole big face is all brought into close contact, therefore the outward appearance Forming Quality of moulding is difficult to protect
Card；Product surface will realize high-light no-trace, it is necessary to design is optimized to mould.
Utility model content
The utility model is parting line can be made thinner there is provided one kind for deficiency of the prior art, and production is difficult during shaping
Give birth to large area overlap and more apparent parting line vestige and the high-light no-trace injection-die die joint knot of production cost can be reduced
Structure.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of high-light no-trace injection-die parting surface structure, including upper mould die joint located at upper mould and under lower mould
Mould die joint, after upper mould die joint is fitted with lower mould die joint described in die cavity in mould inside formation on mould die joint along
Die cavity periphery is provided with mould mold insert, the lower mould die joint and is provided with and the upper mould on upper mould die joint along die cavity periphery
The lower mould mold insert that mold insert is engaged, the upper mould mold insert, the inside of lower mould mold insert are equipped with least two and are connected and through edge
The runner of part, the runner is made up of some big footpath mouthful runners and some paths mouthful runner, the runner and the die cavity on mould
Connection.
Further improved as the utility model, the upper mould mold insert, lower mould mold insert inner flow passage is curvilinear or straight line
Shape.
Further improved as the utility model, the big footpath mouthful runner, the cross section of path mouthful runner are the recessed of arc
Groove.
Further improved as the utility model, the groove width of the big footpath mouthful runner is 3mm~5mm, and groove depth is 0.05mm
~0.1mm.
Further improved as the utility model, the groove width of the path mouthful runner is 1mm~2mm, and groove depth is 0.03mm
~0.08mm.
Further improved as the utility model, on the upper mould mold insert on the upper mould die joint and lower mould die joint under
The docking of mould mold insert constitutes the avoiding hollow groove with gap.
Further improved as the utility model, the gap of the avoiding hollow groove is 3mm~5mm.
The utility model has the advantage of：The utility model is due in upper mould die joint, a pair pairs of lower mould parting Surface Design
Claim the upper mould mold insert and lower mould mold insert set, by setting after mold insert so that need the area of contact to subtract between upper and lower mould die joint
It is few, and then the tight ness rating fitted between upper and lower mould die joint is more preferably, presses also even closer so that parting line is thinner, in product
The vestige for being not easy to more apparent parting line occur on the overlap of larger area, product is not likely to produce during shaping or parting will not be produced
The vestige of line.Secondly, the utility model also runs through in upper mould mold insert and the design of lower mould mold insert on the runner of mold insert, runner and mould
Die cavity connection, further reduction die cavity converge in die cavity because of hot melting plastic gas or extraneous gas, lift mold cavity gas
The exhaust effect of body.
More clearly to illustrate architectural feature of the present utility model and effect, come below in conjunction with the accompanying drawings with specific embodiment pair
It is described in detail.

Fig. 2 is upper mould 1 of the present utility model and the 2-in-1 mode structure schematic diagram of lower mould；
Fig. 3 is partial enlarged drawing in Fig. 2；
Fig. 4 is the sectional view of runner 5 of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The high-light no-trace injection-die parting surface structure provided refering to accompanying drawing 1 to accompanying drawing 4, the present embodiment, including located at upper
The upper mould die joint 10 of mould 1 and the lower mould die joint 20 located at lower mould 2, upper mould die joint 10 fitted with lower mould die joint 20 after
The periphery of die cavity 3 is provided with upper mould mold insert 101, lower mould die joint 20 on the die cavity 3 of mould inside formation, upper mould die joint 10
On be provided with the lower mould mold insert 201 being engaged with the upper mould mold insert 101 on upper mould die joint 10 along the periphery of die cavity 3, upper mould edge
Part 101, the inside of lower mould mold insert 201 are equipped with least two runners 5 for being connected and running through mold insert, and runner 5 is by some big footpaths
Mouth runner 51 and some paths mouthful runner 52 are constituted, and runner 5 is connected with the die cavity 3 on mould.
This high-light no-trace injection-die parting surface structure, upper mould mold insert 101, lower mould mold insert 201 inner flow passage 5 it is curvilinear
Or it is linear.Big footpath mouthful runner 51, the groove that the cross section of path mouthful runner 52 is arc.The groove width of big footpath mouthful runner 51 is
