Abstract

The invention discloses a compression-molding mold for a pipeline anti-wear cover and belongs to the technical field of machinery manufacturing. The compression-molding mold for the pipeline anti-wear cover comprises an upper mold and a lower mold, wherein the compression surface of the upper mold and that of the lower mold are curved surfaces which are matched in a concave-convex mode. The lower portion of the lower mold is provided with a discharging device through a bottom plate. The discharging device comprises an ejector rod and an adjustable bolt which are respectively arranged at the two ends of a sleeve. A spring is arranged between the ejector rod and the adjustable bolt. A through hole which inserts into the ejector rod is formed in the lower portion of the lower mold. According to the compression mold for the pipeline anti-wear cover, the discharging device is added to the lower mold so that a compression-molded curved plate of the pipeline anti-wear cover can be taken out of a mold cavity of the lower mold easily.

Description

Pipeline anti-abrasion cover casted die mould

Technical field

The present invention 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, the pipeline of its conveying 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, be have the semicanal corresponding to pipeline turn of bilge, its required precision is high; The production of existing anti-abrasion cover, form with the mould compacting that the die mould face of upper die and lower die is the concavo-convex curved surface matched, 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.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of pipeline anti-abrasion cover casted die mould, this pipeline anti-abrasion cover casted die mould can solve compressing after the curved slab difficulty problem of taking out from the die cavity of counterdie of pipeline anti-abrasion cover.

In order to solve the problem, the technical solution adopted in the present invention is: this pipeline anti-abrasion cover casted die mould, comprise upper die and lower die, the die mould face of described patrix and the die mould face of described counterdie are the curved surface of male-female engagement, the bottom of described counterdie is connected with device for discharging by base plate, described device for discharging comprises the push rod and adjusting bolt that are separately positioned on sleeve two ends, is provided with spring between described push rod and adjusting bolt, and the bottom of described counterdie offers the through hole inserting 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 limited by long limit circular arc and minor face circular arc, 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 have employed technique scheme, the present invention compared with prior art has following beneficial effect:

Add device for discharging in counterdie of the present invention, make compressing after the curved slab of pipeline anti-abrasion cover easily take out from the die cavity of counterdie.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the invention will be further described:

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 die mould face of patrix 1 and the die mould face of counterdie 2 are the curved surface of male-female engagement, curved surface is limited by long limit circular arc and minor face circular arc, 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, the bottom of counterdie 2 and base plate 3 all have a through hole be 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 adjusting bolt 4-4 that are separately positioned on sleeve 4-2 two ends, be provided with spring 4-3 between push rod 4-1 and adjusting bolt 4-4, push rod 4-1 is inserted in the through hole that counterdie 1 and base plate 3 have.

Embodiment two

Curved surface is limited by long limit circular arc and minor face circular arc, 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 one.

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