Abstract
The utility model discloses a locating rod of a fixed die for injection molding based on a plastic lens. The locating rod mainly comprises a main body (1), and is characterized in that a protecting layer (2) is arranged on the main body (1). The locating rod, provided by the utility model, has the advantages of simple structure, low cost and capability of improving the wear resistance of the locating rod, so that the service life of the locating rod is prolonged, and the production cost is reduced, thus the locating rod is suitable for polarization and application.
Description
Technical field
The utility model relates to the backstay of a kind of injection moulding with cover half, specifically is meant a kind of based on the backstay of glass lens injection moulding with cover half.
Background technology
Injection mo(u)lding in mold cavity after when producing glass lens, needing earlier with plastic molting is removed runner and cast gate with material base after the moulding then, processes eyeglass at last.Injection moulding generally includes fixed half and moving half with mould, before injection moulding, need dynamic model and cover half locking be formed an integral body, and through the plastics injection mold cavity of the plug hole on the cover half with fusion, the plastic cool aftershaping of fusion is the eyeglass material base then.Open mould at last, dynamic model and cover half are separated, the material base after the moulding is taken out.With dynamic model and cover half locking the time, need position through the backstay on the cover half; And need during the injection moulding eyeglass repeatedly dynamic model and cover half closure are opened again; Therefore backstay receives great frictional force in the process of mould closes and unlatching, thereby the backstay surface is worn.To influence the positioning accuracy of mould after the backstay surface is worn, and cause the material base moulding bad at last, thereby influence product quality, therefore, the service life of the backstay that uses at present is all not long, after wearing and tearing, can only discard, thereby improve production cost.
The utility model content
It is frayed easily in injection moulding process that the purpose of the utility model is to overcome the backstay of present use; Thereby the defective that has shortened the service life of backstay; Provide a kind of not only simple in structure; And with low cost, can also improve the antiwear property of backstay, thus prolonged backstay service life based on the backstay of glass lens injection moulding with cover half.
The utility model is realized through following technical proposals: based on the backstay of glass lens injection moulding with cover half, mainly be made up of main body, on said main body, also be provided with protective layer.
Further, said protective layer is made by nickel.
Further, said main body is a cylindrical structure, said protective layer is coated on the outer surface of main body.
In order to ensure effect, said protective layer chemical plating is on main body.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, and is easy to use.
(2) main body of the utility model is provided with protective layer, can strengthen the antiwear property of main body, prevents that main body is worn because of friction when installing and dismantle dynamic model, has therefore prolonged the service life of main body, thereby has reduced production cost.
(3) protective layer of the utility model adopts the big and stronger nickel of antiwear property of hardness to be made, can be with the antiwear property of strong protective layer, thus prevent that protective layer is damaged, can the better protection main body.
(4) the protective layer chemical plating of the utility model can better cover on the main body protective layer, thereby can better protect main body on main body, prevents that main body is worn.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Fig. 2 is the vertical view of the utility model.
Wherein, the parts name that Reference numeral is corresponding is called:
1-main body, 2-protective layer.
The specific embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
Embodiment
Like Fig. 1, shown in 2, the utility model mainly is made up of main body 1, the cylindrical structure of said main body 1 for being processed by metal material.In order to strengthen the antiwear property on main body 1 surface, prevent that main body 1 is worn because of frictional force, on said main body 1, also be provided with protective layer 2, and this protective layer 2 is coated on the outer surface of main body 1 when mould closes and unlatching.For better protection main body 1, prevent that protective layer 2 is worn, said protective layer 2 adopts hardness to be made than big and the stronger nickel of antiwear property, and passes through chemical plating on main body 1.
As stated, just can realize the utility model preferably.
Claims (4)
1. based on the backstay of glass lens injection moulding, mainly form, it is characterized in that: on said main body (1), also be provided with protective layer (2) by main body (1) with cover half.
2. according to claim 1 based on the backstay of glass lens injection moulding with cover half, it is characterized in that: said protective layer (2) is made by nickel.
