Abstract
The utility model relates to a forming mould for molding PET, PC, PMM and compound plastic sheet with the thickness ranging from 0.075 mm to 0.188 mm, belonging to the technical field of moulds, which comprises a female mould and a male mould; a layer of elasticity soft rubber is clung to the inner wall of a mould cavity formed by the female mould and the male mould; the elasticity soft rubber is adhered on the female mould; the elasticity soft rubber has the performances of both plastic and rubber. Due to the forming mould, the elasticity soft rubber and a metal die are combined, offering a soft forming mould suitable for inner mould insertion decoration injection molding, so the utility model has the advantages of correcting precision error of making the mould and uneven thickness of the plastic sheet, satisfying molding demand of the plastic sheet, simultaneously protecting the plastic sheet surface during molding, protecting the plastic sheet surface from damag by the metal mould, effectively enhancing the molding effect, and improving finished product rate.
Description
Technical field
The utility model relates to technical field of mold, relates to a kind of mould of PET, PC, PMMA and the complex plastic sheet material that is used for moulding 0.075mm～0.188mm thickness range particularly.
Background technology
In recent years, the structure of domestic electronic appliances and communication product is more and more exquisite, and appearance and modeling is more and more abundanter, and the decorative effect on plane can't satisfy the demand in market, in this case, the decorated injection-moulded technology of in-mode inserts (IML) has obtained development at full speed.The decorated injection-moulded technology of in-mode inserts is the international at present surface decoration technique that is in fashion, be mainly used in the incrustation and the functional panel of household appliances, be commonly used on the outward appearance part such as panel, sign in handset viewing window eyeglass and shell, washer control panel, refrigerator control panel, Air-Conditioning Control Panel, automobile instrument panel, the multiple field of electric cooker control panel.
IML is that the decorative pattern with product at first is printed on the plastic film sheet material, get off the plastic sheet shape as required that prints is die-cut then, again the die-cut film that gets off is molded into the curved surface that needs, at last film die-cut and that moulding is finished is placed in the injection mold cavity, after the mold-closing injection film and plastic material is synthesized final products.
Because in mould, be placed with the plastic sheet of a slice forming in the IML injection moulding process, so IML is injection molded into pattern and common to be injection molded into pattern different.But be used at present plastic sheet is carried out mostly still common metal die of forming mould, close by die and punch and it is carried out moulding in the middle of plastic sheet being pressed in after tight.Exist in the existing forming process because trueness error and plastic sheet itself that mould is made are in uneven thickness, shaping mould die and punch close the middle phenomenon that has inhomogeneous gap in tight back, the briquetting pressure that causes plastic sheet to be subjected to is inconsistent, makes that the product yields of final molding is low.
The utility model content
Technical problem to be solved in the utility model provides the decorated injection-moulded and mould that can improve yield rate of a kind of suitable in-mode inserts.
The utility model is achieved through the following technical solutions:
Design a kind of mould, include die and punch, on the mould intracavity wall of die and punch formation, be attached with elasticity flexible glue layer.
As the improvement of such scheme, elasticity flexible glue layer is attached on the die, and this elasticity flexible glue has the performance of plastics and rubber concurrently.Its hardness range is Shao A80～95 degree, and the hot strength scope is 25～45MPa, and the percentage elongation scope is 400～600%
The utility model has following remarkable result compared to existing technology:
Mould provided by the utility model; the elasticity flexible glue combined with metal die provides a kind of suitable in-mode inserts decorated injection-moulded soft shaping mould; can not only remedy sum of errors plastic sheet thickness inhomogeneous of Mold Making precision; satisfy the requirement of plastic sheet moulding; can also in the process of moulding, protect simultaneously the surface of plastic sheet; avoid the plastic sheet surface to be damaged, improved molding effect effectively, improved yield rate by metal die.
Description of drawings
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 is a cross-sectional schematic of the present utility model
Shown by reference numeral: 1. panel, 2. punch, 3. convex template, 4. plastic sheet, 5. elasticity flexible glue, 6. concave template, 7. die, 8. base plate.
The specific embodiment
Referring to Fig. 1, a kind of shaping dies includes die 7 and punch 2, and punch is arranged on the convex template 3, and convex template connects as one with panel 1.Die is positioned at concave template 6, and concave template is fixed on the base plate 8.Surface attachment one deck elasticity flexible glue 5 of above-mentioned die.This elasticity flexible glue is selected from the plastic material of the performance that has plastics and rubber concurrently, make it have good mechanical strength, better elastic and anti-wear performance, resistance to chemical attack, tear-resistant simultaneously, its hardness range is Shao A80～95 degree, the hot strength scope is 25～45MPa, and the percentage elongation scope is 400～600%.
The utility model adheres to the shape that the elasticity flexible glue can meet punch well on die, thoroughly solved because the gap problem of non-uniform that the mould accuracy of manufacture is produced.And because flexible glue has better elastic; can protect the appearance of plastic sheet 4 in the die cavity; can remedy error in uneven thickness when the plastic sheet moulding again, simultaneously plastic sheet is fitted on the punch well, molding effect has had bigger improvement than metal pattern.
Mould provided by the utility model is adapted at the IML field and is used for PET, PC, PMMA and the complex plastic sheet material of moulding 0.075mm～0.188mm thickness range.
Claims (3)
1. a mould includes die (7) and punch (2), it is characterized in that: be attached with one deck elasticity flexible glue (5) on the mould intracavity wall that described die and punch form.
2. mould according to claim 1 is characterized in that: described elasticity flexible glue is attached on the die.
3. mould according to claim 2 is characterized in that: described elasticity flexible glue with plastics and rubber property, its hardness range are Shao A80～95 degree, and the hot strength scope is 25～45MPa, and the percentage elongation scope is 400～600%.
