Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in Figure 1 to Figure 3, a kind of injection machine inverted mold is anti-runs the structure of burr, including is arranged on injection machine
Cope plate 100 and lower template 200, mold cavity 500, the cope plate are provided between the cope plate 100 and lower template 200
100 lower sections middle part are provided with hot mouth 300, and the lower section sidepiece of cope plate 100 is provided with oblique top mold insert 400, and the oblique top mold insert 400 wraps
Lower contacts portion 420 and upper lobes portion 410 are included, the upper lobes portion 410 includes facade 411, the horizontal plane being sequentially connected
412 and inclined-plane 413, the facade 411 contacted with shaped article end.In the injection moulding process of product is carried out using injection machine,
Ensure that cope plate 100 and lower template 200 are in closure state first, now mold cavity 500 is kept closed, and passes through upper mould
The hot mouth 300 at the lower section of plate 100 middle part injects injection raw material in mold cavity 500, and product is stripped after shaping.Injection mould
The hot mouth 300 of tool refers to the part that the hot flow path front end of mould is set, injection raw material heating and melting in forming machine, also liquid
The injection raw material of state sequentially passes through the hot mouth 300 of hot flow path and front end again, eventually enters into mold cavity 500, injection raw material is in mould
Final injecting products are formed in tool die cavity.Oblique top mold insert 400 includes two parts, and a part is under corresponding injecting products profile
Portion's contact site 420, also have be used to place the upper lobes portion 410 for running burr in addition, upper lobes portion 410 is mainly used in draping over one's shoulders race
Cutting edge of a knife or a sword phenomenon is effectively controlled, and avoids causing the influence of surface quality after being molded large product.The structure is applied to large-scale
In the production process of injection machine, such as 2400T injection machines, because large size plastic jetting-moulding device has the characteristics of injection pressure is big, it is used in combination
The characteristic of inverted mold, injection raw material are exited into during mold cavity 500 is molded from hot mouth 300, noted
Blow pressure and the influence of flow direction, oblique top is easily caused to produce gap, and then injection raw material burr formed here downwards,
The strong influence surface quality of product, causes the rise of defect ware or percent defective, wastes raw material.The oblique top is inlayed
The design of part 400, by being arranged at the upper lobes portion 410 of the top of lower contacts portion 420, to the terminal position of mold cavity 500
Effective barrier effect is played, avoids producing gap, and then is effectively prevented the appearance of burr phenomenon, ensure that product is good
Surface quality, improve the qualification rate of product.
As further optimization, upper lobes portion 410 is right-angled trapezium and right-angle side is disposed in proximity to product side.On
The setting of portion's lug boss 410, on the one hand need to play the terminal position of mold cavity 500 restriction effect, on the other hand will also be just
In processing and fabricating, to reduce cost of investment, for the end side of mold cavity 500, directly make and perpendicular straight in end
Face, effective position restriction can be played a part of, while the manufacture difficulty of the vertical plane is smaller, is easy to reduce equipment cost,
Setting for opposite side, with reference to the profile of oblique top mold insert 400, make and form the inclined-plane seamlessly transitted with lower contacts portion 420
Form, in terms of one side processing, while can also preferably improve the intensity of whole oblique top mold insert 400, ensure oblique top mold insert 400
With the good effect for bearing injection pressure, the frequency of device damage is reduced, improves the service life of equipment.
As further optimization, upper lobes portion 410 and lower contacts portion 420 are formed in one.In order to further protect
The bulk strength of whole oblique top mold insert 400 is demonstrate,proved, upper lobes portion 410 and lower contacts portion 420 are integrated into process
The form of type, avoid therebetween by the later stage with reference to caused by the defects of intensity deficiency, simultaneously as large injection mold
Injection pressure is larger, and the oblique top mold insert 400 being put together easily produces dislocation movement etc. in the presence of larger injection pressure
Phenomenon, it is difficult to ensure the size and positional precision of product, so needing to make in upper lobes portion 410 and lower contacts portion 420
Integrally formed form is made, to ensure the performance of equipment.
As further optimization, oblique top mold insert 400 uses grafting glue sealing structure.Original plane sealing is inserted through instead
The form of sealing, sealing are that the position for stopping plasticity effect is played to injection raw material, and original oblique top is in the end of product using flat
The form of face sealing, it is difficult to ensure gapless, and be inserted through sealing and one is then formed in the end of product perpendicular to the flat of end
Face, effectively avoid producing burr at this, ensure the surface quality of injecting products.
The utility model structure design advantages of simple, in the injection moulding process of the large-scale inverted mold of injection machine, even if by
The influence flowed to injection pressure and injection raw material, also can effectively avoid oblique top produce gap downwards and caused by burr,
And then the defect ware even generation of waste product are effectively avoided, the processing cost in later stage is reduced, ensure that the entirety of injecting products
Quality, the production efficiency of product is improved, create good economic benefit, there is wide applicability.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
