The present invention relates to injection mold field, more specifically to a kind of line position mould emptier of in-mould laminating injection mold.Including the line position (10) for the die cavity that injection mold is collectively formed with fixed mold (18), dynamic mould core (19), be additionally provided with for limit the line position (10) position in injection mold shovel (8), the shovel (8) motion can be driven to release the first actuating unit (22) of its position restriction to the line position (10) in injection mold, and can drive the line position (10) make it away from injection mold die cavity the second actuating unit (23).Shovel and line position in injection mold are adjusted under the drive of these actuating units, line position is set to depart from back-off with the product after shaping, compared with the mode that line position is taken out in traditional artificial die sinking, the present invention realizes mechanical operation in injection mold, and can reduce in injection moulding process and once mold, injection cycle effectively is shortened, injection moulding process production efficiency is improved.
Description
Technical field
The present invention relates to injection mold field, more specifically to a kind of line position ingot stripper of in-mould laminating injection mold
Structure.
Background technology
Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches.Refer specifically to melt heated
The material of change injects die cavity, after cooling and solidifying, obtains formed products.Injection mold is a kind of instrument for producing plasthetics；
It is to confer to the instrument of plasthetics complete structure and accurate dimension.Injection mold is typically made up of dynamic model and cover half two parts, is moved
Mould 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.In injection moulding
Dynamic model constitutes running gate system and die cavity with cover half closure, and dynamic model and cover half separate to take out plastic products during die sinking.
Although the structure of mould is according to plastics variety and the type of performance, the shape of plastic products and structure and injector
It is ever-changing Deng different, but basic structure is consistent, i.e., mainly by running gate system, forming part, gas extraction system, temperature control
System and ejection system composition.Wherein running gate system and forming part be with the direct contact portion of plastics, and with plastics and product
And change, it is most complicated, change maximum in mold, it is desirable to process finish and precision highest part；Running gate system refers to modeling
Expect the runner section entered from nozzle before die cavity, including sprue, cold slug well, runner and cast gate etc..Forming part refers to structure
Into the various parts of article shape, including dynamic model, cover half and die cavity, core, curved lever and exhaust outlet etc..
In order to strengthen and/or change the outward appearance of product, flexible touch and quality are improved, it usually needs in the modeling of hard form
Material products outer surface addition one covers thin layer, such as fabric, blanket layer, cloth, artificial leather (PVC skins), corium.Traditional addition is cladded with
The technique of cap rock is to first pass through molded plastic part, then coating is attached on the surface of working of plastics using bonding agent.This
The method of kind does not only exist the air pollution problems inherent of bonding agent, but also there is many processes, cost height, sticks the deficiency such as not close.
In-mould laminating moulding process is a kind of new injection molding process., will before mould matched moulds in in-mould laminating technique
The laminated material such as cloth, artificial leather (PVC skins) or corium, carpet bar is put into mold cavity and (is generally hung at dynamic model part), carries out
Mould matched moulds, is then molded, pressurize and cooling, because plastic melt is contacted in shaping with laminated material and is fused one
Rise, such laminated material is just securely attached to the surface of molded plastic article, so that it is the lamination material such as skin or cloth to obtain appearance
Material, the inside are the novel injection molding products of plastics.Due to being put into laminated material in die cavity, it is necessary to relatively low pressure (1.5~
40bar), mould (when especially melt initially enters die cavity) is injected, to avoid the damage of laminated material slower velocity-stabilization
Bad or sliding, therefore also turn into low-pressure injection molding.
In-mould laminating technique only needs one-shot forming, thus with very high processing efficiency, and can save up to 15%~
30% cost, belongs to environment-friendly type technique, need not add any bonding agent during being fitted in mould, will not be released in use
Put volatile solvent；Surface decoration layer after in-mould laminating can produce very strong adhesive force between molded item, in use certainly
It will not fall off or ftracture, and with good surface abrasion resistance.
It is die joint with conventional injection difference, enters glue, dynamic model line position, dossal pin and the design for playing pin.In note
In the ejecting mechanism design of mould, there are mechanical line position, oblique top, oblique bullet etc., the row of mould in the common mechanism for departing from product back-off
Position mechanism refers to result in side core-pulling or undercut and homing action to haul out product back-off, the machine of the position such as sunken
Structure.For traditional injection mold, need line position being removed from the molds after the completion of injection, production is then taken out from mould
Product, product takes off very difficult during back-off when matched moulds state pressurize, generally requires increase and once molds, line position is ejected,
Realize that the demoulding obtains product, causes die sinking action and process very cumbersome again afterwards, but also greatly extend injection cycle,
Reduce production efficiency.
