Abstract
The utility model discloses a mold for manufacturing a well lid framework. The mold comprises a disc body. A plurality of protruding parts are arranged on the disc body. Vertically and horizontally staggered inner ring grooves are formed on the disc body by the protruding parts. An outer ring groove is formed between the edges of the protruding parts and the outer edge of the disc body. According to the mold for manufacturing the well lid framework, due to the arrangement of the disc body with the protruding parts, a long glass fiber can be conveniently used for manufacturing a long glass fiber composite grid mesh in a coiling mode, when the mold for manufacturing the well lid framework is used, the problem that the long glass fiber composite grid mesh is large in manufacturing difficulty and irregular in shape is solved, the formed inner ring grooves and the formed outer ring groove are beneficial to carrying out coiling machining through the whole long glass fiber as far as possible, therefore, after whole compression molding forming, the layered phenomenon is not prone to occurring, a whole product has certain flexibility and has high alternating stress resistant capacity, a well lid can not be completely broken after being fractured, the buffering time for replacing and maintaining the vertical shaft cover plate is reserved, and the safety performance is improved.
Description
Technical field
The utility model relates to vertical shaft cover plate production field, manhole cover plate for example, sewer cover plate, load-bearing downspout strainer, cable channel cover plate etc., particularly a kind of mould for making the well lid skeleton.
Background technology
Existing vertical shaft cover plate, for example the cover plate of sewage inspection well adopts cast iron materials more, steel wire fibre concrete material or glass fiber composite material.
Adopt for example vertical shaft cover plate of BMC glass fiber composite material of glass fiber composite material.Skeleton need to be set in well lid, the existing cage of reinforcement that adopts, easy and BMC glass fiber composite material layering breaks away from.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of mould for making the well lid skeleton, can make easily the well lid skeleton.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of mould for making the well lid skeleton, comprise disk body, disk body is provided with a plurality of lug bosses, described a plurality of lug boss forms crisscross interior ring recess at disk body, forms an outer ring recess between the edge of a plurality of lug bosses and the outer rim of disk body.
The arrangement of aliging in length and breadth of described a plurality of lug boss.
The degree of depth of described outer ring recess is greater than the degree of depth of interior ring recess.
Described disk body is circle or polygon.
Adopt the roving glass fiber composite material to make skeleton, because the material of skeleton and remainder is close, therefore be difficult for layering, but new problem is, the intensity of roving glass fiber composite material still is lower than reinforcing bar, only equally the roving glass fiber composite material is arranged strength deficiency in length and breadth with reinforcing bar, and cutting roving glass fiber composite material also comparatively bothers, because the roving glass fiber composite material has certain flexible, also there is difficulty in its bending.
A kind of mould for making the well lid skeleton that the utility model provides, by the disk body with a plurality of lug bosses that arranges, can utilize easily the roving glass fiber coiling to make the compound aperture plate of roving glass fiber, it is large to adopt the utility model to overcome the compound aperture plate manufacture difficulty of making roving glass fiber, the problem of shape irregularity, the roving glass fiber that the interior ring recess that forms and outer ring recess are beneficial to whole as far as possible of employing coils processing, thereby after the integral die moulding, be not prone to the phenomenon of layering, it is certain flexible that whole product is had, ability with higher anti-alternating stresses, well lid can not disconnect after breaking fully, reserve the buffer time of changing and keeping in repair the vertical shaft cover plate, improved security performance.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Fig. 3 is the structural representation of the compound aperture plate of roving glass fiber that adopts the utility model and make.
Fig. 4 is the structural representation that the utility model is used to make downspout strainer.
Among the figure: outer ring recess 1, lug boss 2, interior ring recess 3, disk body 4, the compound aperture plate 5 of roving glass fiber.
The specific embodiment
In Fig. 1,2,4, a kind of mould for making the well lid skeleton comprises disk body 4, and disk body 4 is provided with a plurality of lug bosses 2, described a plurality of lug boss 2 forms crisscross interior ring recess 3 at disk body 4, forms an outer ring recess 1 between the outer rim of the edge of a plurality of lug bosses 2 and disk body 4.Structure thus, the roving glass fiber of being convenient to have applied the resin-coating layer is coiled into the shape of aperture plate in interior ring recess 3 and outer ring recess 1, owing to adopted interior ring recess 3 and outer ring recess 1 to carry out spacing, coiling compound aperture plate 5 shapes of roving glass fiber out are regular, and uniform specification, be convenient to the processing of later stage operation,, overcome the flexible problem of roving glass fiber composite material self by adopting thinner roving glass fiber polydisc around which floor mode is also larger.The roving glass fiber of indication refers to the roving glass fiber bundle in this example, refers to that more carefully cross section only is the roving glass fiber bundle of finished product cross section 1/5 ~ 1/2.The compound aperture plate 5 of roving glass fiber of making be the well lid skeleton as shown in Figure 3.In Fig. 1,4, described disk body 4 is circle or polygon.For example be used for making the skeleton of downspout strainer among Fig. 4, the shape of this disk body 4 is rectangle, for some special occasions, need to use for example position of triangle, hexagon or octagon well lid, and correspondingly disk body 4 also is triangle, hexagon or octagon.Alleged well lid comprises the manhole cover plate in this example, sewer cover plate, load-bearing downspout strainer, cable channel cover plate etc.
In the scheme such as Fig. 1,4 of optimizing, the arrangement of aliging in length and breadth of described a plurality of lug bosses 2.Structure is convenient to the coiling processing of roving glass fiber thus.
In the scheme of optimizing, the degree of depth of described outer ring recess 1 is greater than the degree of depth of interior ring recess 3.Structure thus, be convenient to hold more roving glass fiber in the ring recess 1 outside, because compound aperture plate 5 performances of roving glass fiber that adopt the roving glass fiber of the least possible radical to process are better, therefore outside ring recess 1 just to have more roving glass fiber overlapping, the degree of depth of the outer ring recess 1 of employing is more smooth greater than the compound aperture plate 5 of roving glass fiber that the degree of depth of interior ring recess 3 is conducive to make.
