Abstract
The invention discloses an injection mould and a method of collecting volatile substances in injection moulding gas. A cavity plate of the injection mould is provided with a cavity, a cast gate connected with the cavity and a runner connected with the cast gate and is perforated with gas guide holes which are communicated with the air; an insert which is provided with a slot at its central section is arranged on the cavity plate, the groove is communicated with the gas guide holes, the insert is provided with venting gaps, and the groove is full of glass flakes matching with the venting gaps. According to the invention, when the injection mould is used for injection moulding, gas produced in the process of injection moulding passes through slits among the glass flakes and adheres onto the glass flakes after condensation, the glass flakes are taken down after injection moulding is completed, and then collection of the volatile substances in injection moulding gas is finished. The injection mould provided in the invention has a simple structure; gaseous volatile matters generated in injection moulding are collected by using the designed glass flakes, and no extra design of a pipeline is needed, thereby substantially improving efficiency of gas collection. The injection mould is applicable to a variety of tests of modified thermoplastic plastics and provides basis for modification and optimization design of materials.
Description
Technical field
The invention belongs to the injection mo(u)lding field, be specifically related to the method for a kind of injection mold and collection injection moulding gaseous volatilization thing thereof.
Background technology
In injection molding process; Moulding attendes that weld mark place aberration appears in regular meeting or gloss is bad, gas trace, precipitate; Even defective such as Jiao Hen; Its reason has aspects such as material, mould and article construction, Shooting Technique, and one of them reason possibly be because the high temperature plastic cement melt of molten condition during through cast gate filling die cavity, receives and sheared by force the perhaps thermo-labile generation decomposition of material component or separate out.The material that decomposes in the stowing operation or separate out is gaseous state, can be solid-state after the condensation.These materials can directly influence the performance of material and the apparent mass of moulding; For the performance of studying material in the injection molding process and gas volatile matter to the influence of goods injection defect, need a cover can collect the device of material gas volatile matter in the injection molding process.
The common method of on injection mold, collecting at present the gaseous volatilization thing is at the die cavity end air drain that begins to rehearse; Receive receiving flask through pipeline then or the balloon condensation obtains; The weak point of this method: the one, residual material is not easy cleaning in the tube wall, needs frequent cleaning when reloading test; The 2nd, the volatile matter on the collection container is inconvenient to take out and is chemically examined, and the material of collection container can influence the accuracy that volatile constituent is identified.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; A kind of injection mold is provided; The gaseous volatilization thing that said injection mold produces in the time of can collecting injection mo(u)lding easily, avoided existing cleaning inconvenience and present stage to be difficult to collect after, volatile matter is difficult to problems such as taking-up chemical examination.
The present invention provides a kind of collection method of injection moulding gaseous volatilization thing simultaneously.
Above-mentioned purpose of the present invention is achieved through following technical scheme:
A kind of injection mold comprises solid plate, cavity plate and moving platen, and cast gate that said cavity plate is provided with die cavity, link to each other with die cavity and the runner that links to each other with cast gate have gas port on the said cavity plate, gas port and atmosphere; Said cavity plate is provided with the inserts of a middle part fluting, and groove is connected with gas port, has exhaust clearance on the inserts, is full of that insert and sheet glass its coupling in the groove.
The shape of the groove on the inserts can have any shape, regular or irregular can, as a kind of preferred version, the groove on the said inserts is preferably rectangle, square, circular, ellipse or rhombus.
As a kind of most preferably scheme, the groove on the said inserts most preferably is rectangle.
Sheet glass described here is conventional sheet glass, and the plane of sheet glass is not absolute smooth, therefore when these sheet glass are placed vertically, can have small gap between sheet and the sheet.As a kind of most preferably scheme, said sheet glass most preferably is slide.
" inserting " described here is meant that the plane of sheet glass and groove are perpendicular.
As a kind of preferred version, the opening direction of said exhaust clearance is preferably consistent with the opening direction of cast gate.
As a kind of preferred version, said exhaust clearance is preferably the groove that the degree of depth is 0.01～0.2mm.
The main effect of gas port can guarantee that the gas collection channel is unimpeded.
A kind of collection method of injection moulding gaseous volatilization thing; Comprise the steps: to adopt said injection mold to carry out injection mo(u)lding, the gas that injection mo(u)lding produces is through the slit between sheet glass, and condensation sticks on the sheet glass; Injection moulding is taken off sheet glass and is promptly accomplished collection after accomplishing.After collect accomplishing, can sheet glass directly be put into the solution that corresponding solvent can obtain volatile matter and chemically examine, and glass can not be dissolved in solvent, can not produce and disturb the composition of volatile matter.
Compared with prior art, the present invention has following beneficial effect:
Injection mold of the present invention, the gaseous volatilization thing that the sheet glass through design produces during to injection mo(u)lding is collected, and does not need to design in addition pipeline, has improved the efficient that gas is collected greatly; Adopt injection mold of the present invention to carry out the gaseous volatilization thing is collected; After injection moulding is accomplished, take off sheet glass and promptly accomplish collection, simple to operate, sheet glass can not produce the composition of volatile matter and disturb; Collection has the sheet glass of volatile matter directly to put into solvent to chemically examine, easily and effectively; The present invention is applicable to the test of various modified thermoplastics, for material modification and optimal design provide foundation.
