Abstract

The utility model discloses a bottle mouth die, which comprises a die body which is divided into two parts and a liner ring. The utility model is characterized in that the inner and the outer surfaces of the die body and an upper opening of the liner ring are coated with a spraying and welding layer, and the body height of the spraying and welding layer is two to four millimeters. The utility model has the advantages of firm structure, high durability and material saving, and the degree of finish of products is guaranteed.

Description

Bottle-mouth die

The utility model relates to the moulding of glasswork, be in the production of hollow glass article blow-molded glass, make hollow glass article produce the parts of special shape, specifically form the parts of screw thread or lip at hollow glass article mouth place; Eck mould.

Domestic original Bottle-mouth die wearing quality is relatively poor, also there are many problems in the quality that causes the product of toilet production, and existing at present many manufacturers have adopted the import Bottle-mouth die that is lined with enhancement Layer, and this Bottle-mouth die wearing quality increases, but also can only use 48 hours, and still need often to change.The thickness of above-mentioned enhancement Layer is generally more than 4.2 millimeters, the cost height.

The purpose of this utility model provides a kind of firm and durable, saves the Bottle-mouth die of precious materials.

Technical solution of the present utility model is: a kind of Bottle-mouth die, comprise in two die body and grommet, and the difference of itself and prior art is: the upper shed surfaces externally and internally of die body and grommet has spray-welding coating, and the body thickness of spray-welding coating is the 2-4 millimeter.

Spray-welding coating described in the utility model is a multilayered structure, every bed thickness 0.08-0.12 millimeter.Certainly, also can adopt other suitable gauges.

The every layer thickness of multiwalled spray-welding coating of the present utility model is good with 0.1 millimeter.

Spray-welding coating described in the utility model adopts Ni-based 103 powder or 101 powder to constitute.

The body thickness of the spray-welding coating described in the utility model is good with the 3.2-3.8 millimeter.

The utility model has the advantages that: sound construction, wearing quality is good, result of use be better than than the big external product of thickness, can save a large amount of precious materials, and guarantee the smooth finish of product.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the structure iron of a kind of Bottle-mouth die of the present utility model.

Fig. 2 is half a side-view of Bottle-mouth die shown in Figure 1.

Fig. 3 is the structure iron of grommet.

Fig. 1, Fig. 2, Fig. 3 have described an embodiment of the present utility model.Constituted complete Bottle-mouth die by half outer die body 1, second half outer die body 2 and grommet 4 in this example.Surfaces externally and internally in the upper shed of external mold and grommet 4 has the surfacing

enhancement Layer

3,5 that is formed by Ni-based 103 powder or 101 powder surfacings, the body thickness of this spray-welding coating 3,5 is about 3.7 millimeters, certainly, also can adopt from the arbitrary thickness value between the 3-4 millimeter or other appropriate value.Its technological process is: earlier work in-process mouth mould is placed in the stainless steel reflection pot and heats to about 800 ℃, again the mouth mould is placed on the anchor clamps and is heated to 1000 ℃ with special powder spray gun 2/h number (having commercially available), begin to carry rifle spray one deck powder, and rapidly temperature is added between 1050 ℃-1100 ℃, see that with the naked eye the boron material in the powder begins slime flux, nickel powder also begins to dissolve, begin to add another layer of spray powder this moment again, be about 0.1 mm thick (or other appropriate value) at every turn, until desired thickness, be placed on insulation annealing in the plant ash behind the surfacing, and then through being machined into the finished product Bottle-mouth die.

Claims
