Description

A kind of die venting structure and there is the mould of this exhaust structure
Technical field
The utility model relates to Making mold equipment, particularly relates to a kind of die venting structure and has the mould of this exhaust structure.
Background technology
Injection mold is a kind of instrument producing plasthetics; Also be the instrument giving plasthetics complete structure and accurate dimension.A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production.The material melted that is heated is injected die cavity by high pressure by concrete finger, after cooling curing, obtains formed products.
Although the structure of mould may be ever-changing because plastics variety and performance, the shape of plastic products and the type of structure and injector etc. are different, basic structure is consistent.Mould forms primarily of running gate system, thermoregulating system, forming part and constitutional detail.Wherein running gate system and forming part are direct contact portion with plastics, and change with plastics and goods, are the most complicated in mold, change maximum, require processing fineness and the highest part of precision.
Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model and cover half close and form running gate system and die cavity, and during die sinking, dynamic model is separated to take out plastic products with cover half.In order to reduce heavy Design of Dies and manufacturing effort, injection mould have employed standard die set mostly.
In prior art, a kind of flute profile gas outlet offered in a mold, in order to discharge the gas that original and melt is brought into.When melt injects die cavity, formerly be stored in the air in die cavity and the gas brought into by melt must be discharged by exhaust outlet in the end of stream outside mould, otherwise goods will be made with pore, connect bad, mold filling and be discontented with, even goods are burnt because producing high temperature by compression by air accumulation.Generally, steam vent both can be located at the end of melt flowing in die cavity, also can be located on the die joint of mold.The latter offers dark 0.03-0.2mm in die side, the shallow slot of wide 1.5-6mm.In injection, steam vent does not have a lot of melt and oozes out, because passage can block at this place's cooling curing by melt.Be sure not, facing to operating personnel, to hurt sb.'s feelings in case melt surprisingly sprays in the position of offering of exhaust outlet.In addition, also can utilize knock-pin and the fit clearance ejecting hole, the fit clearance etc. of jacking block and stripper plate and core is vented.But the existing mobile phone TPU protective sleeve injection moulding delivery cycle is shorter and shorter, under adjustment injection machine condition, overcome product weld bond, current mark, when in delivery cycle shorter situation, the unstable product fraction defective of injection moulding raises, and is difficult to normal delivery.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of die venting structure and has the mould of this exhaust structure, shortening injection molding cycle, improve product percent of pass.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of die venting structure, comprises rear cavity and is arranged at the core rod above rear cavity, arrange the core rod strong point between described rear cavity and core rod, and the below of the core rod strong point arranges air discharge duct along the edge of rear cavity and core rod junction.
As most preferred embodiment of the present utility model, rear cavity described in the utility model arranges multiple passage, and passage is communicated with air discharge duct, forms exhaust passage.
As most preferred embodiment of the present utility model, each side of core rod described in the utility model and rear cavity junction at least arranges 2 core rod strong points.
As most preferred embodiment of the present utility model, the width of the core rod strong point described in the utility model is 3-5 millimeter.
As most preferred embodiment of the present utility model, the clearance height 0.01-0.02 millimeter of core rod described in the utility model and rear cavity.
As most preferred embodiment of the present utility model, air discharge duct described in the utility model is set to indent air discharge duct.
The invention also discloses a kind of mould, comprise panel, water gap plate, solid plate, front cavity, core rod, rear cavity, moving platen, push rod, ejector retainner plate and base plate successively from top to bottom; Between described core rod and rear cavity, described exhaust structure is set.
Compared with prior art, the beneficial effects of the utility model are: in injection moulding process, the closure state when core rod resets toward the rear mold direction of arrow, air during injection moulding inside mould product glue position flows out toward air discharge duct, thus play scavenging action, shortening injection molding cycle, reduces weld bond current mark product fraction defective, improves product percent of pass and production capacity.

Detailed description of the invention
Purport of the present utility model is to overcome the deficiencies in the prior art, provides a kind of die venting structure and has the mould of this exhaust structure, shortening injection molding cycle, reduces weld bond current mark product fraction defective, improves production capacity.Be described in detail, to be interpretated more in-depth technical characteristic of the present utility model and advantage with reference to accompanying drawing below in conjunction with embodiment.
As shown in Figure 1, 2, a kind of die venting structure, comprise rear cavity 6 and be arranged at the core rod 5 above rear cavity 6, arrange the core rod strong point 12 between described rear cavity 6 and core rod 5, the below of the core rod strong point 12 arranges air discharge duct 11 along rear cavity 6 and the edge of core rod 5 junction.Except air discharge duct 11, rear cavity 6 described in the utility model arranges multiple passage, and passage is communicated with air discharge duct 11, forms exhaust passage.
In order to reach good support effect, core rod 5 described in the utility model at least arranges 2 core rod strong points 12 with each side of rear cavity 6 junction.Preferably, the width of the described core rod strong point 12 is 3-5 millimeter.
As shown in Figure 3,4, the clearance height 0.01-0.02 millimeter of core rod 5 described in the utility model and rear cavity 6.
Air discharge duct 11 described in the utility model is set to indent air discharge duct.Discharged fast by the air-flow of recessed air discharge duct by whole mould.
The utility model only can need machine on grinding machine, empty avoiding degree of depth 0.01-0.02 millimeter beyond rear cavity 6, the core rod strong point 12 the highest, 3 core rod strong points are respectively stayed on length direction both sides, and 2 core rod strong points are respectively stayed on cross direction both sides, strong point width 3-5 millimeter; Closure state rear cavity 6 and core rod 5 clearance height 0.02MM, the core rod strong point 12 prevents core rod 5 from sinking and does not have the effect of exhaust, air when injection moulding inside mould product glue position flows out from the direction of arrow four sides shown in Fig. 1 toward the 0.01-0.02 millimeter gap in the air discharge duct space 13 of air discharge duct 11, under the state of not running peak, exhaust effect can be played.
As shown in Figure 5, the invention also discloses a kind of mould, comprise panel 1, water gap plate 2, solid plate 3, front cavity 4, core rod 5, rear cavity 6, moving platen 7, push rod 8, ejector retainner plate 9 and base plate 10 from top to bottom successively; Between described core rod 5 and rear cavity 6, described exhaust structure is set.
Carry out clear, complete description by the technical scheme in above embodiment to the utility model, obviously described embodiment is the embodiment of the utility model part, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
