Abstract

The utility model discloses a press molding die for a pipeline wear-preventive cover, and belongs to the machinery manufacture technology field. The press molding die comprises an upper die and a lower die. The press molding surface of the upper die and the press molding surface of the lower die are curved surfaces that match in a concave and convex manner. A discharging device is arranged under the lower die via a base plate. The discharging device includes push rods disposed at two ends of a sleeve cylinder respectively, and an adjusting bolt. A spring is arranged between the push rods and the adjusting bolt. The lower portion of the lower die is equipped with a through hole for insertion of the push rods. The lower die is additionally provided with the discharging device, such that a curved surface plate of a pipeline wear-preventive cover that is formed by press molding can be easily removed from a cavity of the lower die.

Description

Pipeline anti-abrasion cover casted die mould

Technical field

The utility model relates to machinery manufacturing technology field, especially a kind of pipeline anti-abrasion cover casted die mould.

Background technology

In the production process of high-pressure boiler, because the pressure of boiler is high, it carries the pipeline of thermal medium also will bear corresponding high pressure, so need to load onto anti-abrasion cover at the turn of bilge cover of pipeline cracky, prevent the wearing and tearing of pipeline, pipeline anti-abrasion cover 5 as shown in Figure 7, Figure 8, is the semicanal having corresponding to pipeline turn of bilge, and its required precision is high; The production of existing anti-abrasion cover, to form with the mould compacting that the die mould face of upper die and lower die is the concavo-convex curved surface matching, because the formed body of the pipeline anti-abrasion cover after compressing is curved slab, this curved slab is difficult to take out from the die cavity of counterdie, so be badly in need of a kind of easily dismounting, convenient taking-up, simple and practical anti-abrasion cover casted die mould.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of pipeline anti-abrasion cover casted die mould, and this pipeline anti-abrasion cover casted die mould can solve the problem that the curved slab difficulty of the pipeline anti-abrasion cover after compressing is taken out from the die cavity of counterdie.

In order to address the above problem, the technical scheme that the utility model adopts is: this pipeline anti-abrasion cover casted die mould, comprise upper die and lower die, the curved surface that the die mould face of described patrix and the die mould face of described counterdie are concavo-convex cooperation, the bottom of described counterdie is connected with device for discharging by base plate, described device for discharging comprises the push rod and the adjusting bolt that are separately positioned on sleeve two ends, between described push rod and adjusting bolt, is provided with spring, and the bottom of described counterdie offers the through hole that inserts described push rod.

In above-mentioned anti-abrasion cover casted die mould technical scheme, technical scheme can also be more specifically: described curved surface is by growing limit circular arc and minor face circular arc limits, the radius of curvature of described long limit circular arc is 66mm～66.18mm, and the radius of curvature of described minor face circular arc is 15.88mm～16mm.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

In counterdie of the present utility model, increase device for discharging, the curved slab of the pipeline anti-abrasion cover after compressing is easily taken out from the die cavity of counterdie.

The specific embodiment

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:

Pipeline anti-abrasion cover casted die mould as shown in Figure 1, Figure 2, Figure 3, Figure 4, comprise patrix 1 and counterdie 2, the curved surface that the die mould face of patrix 1 and the die mould face of counterdie 2 are concavo-convex cooperation, curved surface is by growing limit circular arc and minor face circular arc limits, the radius of curvature of long limit circular arc is 66mm, and the radius of curvature of minor face circular arc is 15.88mm; Counterdie 2 is placed on a base plate 3, on the bottom of counterdie 2 and base plate 3, all have a through hole being interconnected, the lower surface of base plate 3 is connected with a device for discharging 4, as shown in Figure 5, Figure 6, device for discharging 4 comprises the push rod 4-1 and the adjusting bolt 4-4 that are separately positioned on sleeve 4-2 two ends, between push rod 4-1 and adjusting bolt 4-4, be provided with spring 4-3, push rod 4-1 is inserted in the through hole that counterdie 1 and base plate 3 have.

Embodiment bis-

Curved surface is by growing limit circular arc and minor face circular arc limits, and the radius of curvature of long limit circular arc is 66.18mm, and the radius of curvature of minor face circular arc is 16mm; All the other are all identical with embodiment mono-.

When work, first upper and lower mould is contained in respectively on hydraulic press; The upper and lower mould stitching surface centering of must coincideing, then workpiece is placed between upper and lower mould, starting hydraulic press forces together upper and lower mould matched moulds, a slice curved slab is compressing, after parting, the push rod of device for discharging is interted in the through hole of counterdie by base plate, turn adjusting bolt, by the active force of spring, can be taken out compressing curved slab.
