Abstract
The invention discloses a preparation method of a collapsible steel die for manufacturing a large-scale glass fiber reinforced plastic chimney. The preparation method mainly comprises preparation of a die body and a demoulding apparatus. The preparation method of the die for manufacturing the large-scale glass fiber reinforced plastic chimney provided by the invention has strong operationality and high production efficiency; the die is convenient for demoulding product and non-deformable, and can be used continuously for many times; and the product has good quality of an interior surface and accurate dimension. The method can overcome the disadvantages of poor quality of internal layer, low size precision and difficulty in jointing of a product manufactured by a die for glass fiber reinforced plastic chimney in the prior art, so as to improve quality of the glass fiber reinforced plastic chimney product and increase production efficiency.
Description
Affiliated technical field
The present invention relates to a kind of preparation method for the mould of making fiber glass reinforced plastic chimney, be specifically related to a kind of preparation method for the telescopic type steel die of making the large glass steel stack.
Background technology
At present, using the production mould of more LARGE DIAMETER FRP product is vertical winding mould or horizontal frame type mould.
The major defect be wound around during vertical winding shows: dolly is vertical motion, without continuous operating platform, while being wound around unidirectional cloth, impregnation, roll-in bubble, often disconnects, and affects the goods internal soundness; The gel content demand of chimney goods is higher, easier gummosis during vertical winding, and the product gel content is wayward; Gummosis while being wound around for alleviating, also need to leave tapering during Mold Making, cause the uneven phenomenon of product docking port, is unfavorable for installing; Vertical winding mould epidermis generally adopts five-ply board to coat, fragile, poor durability.
The major defect that horizontal frame type mould is wound around shows: there are seam and poor rigidity in mould epidermis place, fully roll-in while making product; Also need during the demoulding to break internally mold integral, make mould very easily be out of shape, the surface quality of product is difficult to control; And the defect of rigidity deficiency also makes it can not meet successional production in enormous quantities.
Therefore, necessary on existing basis, research and develop a kind of rational in infrastructure, easy to make, zero draft, rigidity is high, durability is strong, production efficiency is high for making the mould of chimney.
Summary of the invention
Goal of the invention: the present invention is in order to solve the deficiencies in the prior art, provides a kind of rational in infrastructure, easy to make, and zero draft, rigidity are high, and durability is strong, production efficiency is high for the preparation method of the firm molding jig of telescopic type of making the large glass steel stack.
Technical scheme: in order to realize above purpose, the technical solution used in the present invention is:
The preparation of a, die main body
First, according to the dimensional requirement of chimney product, manage and inner frame preparing centre.By the inner frame welding on central tube.At skeleton outer cladding epidermis, epidermis can adopt the manganese plate that 3mm is thick.Cut open longitudinal seam at outer surface.Polish die surface until surface-brightening with sized flap wheel.
The preparation of b, stripper apparatus
Mould cut open seam inner two across between, retract cylinder is set, in mould ends, axial ejection cylinder is set.Need connect being rigidly connected between the inner frame that is placed in the shrinkage joint place during winding, when the needs demoulding, releasing is rigidly connected, retract and can realize the overall shrinkage of mould in the time of by the retract cylinder piston rod, mould and product section are broken away from, recycle axial oil cylinder ejecting product, product is thoroughly broken away from mould.After the final demoulding completes, in the time of by the retract cylinder piston rod, eject, realize the mold shape recovery, need after recovery again to be rigidly connected.
Beneficial effect: the beneficial effect for the telescopic type steel die of making the large glass steel stack provided by the invention is, the mold integral zero draft, and the docking of the chimney product of producing is convenient; The die size precision is high and not yielding; Be easy to impregnation, roll-in in production process, the inside and outside surface quality of the product of producing is good; The product disposal molding; Mold Making is convenient, and production efficiency is high and can meet continuous large batch of production.
The accompanying drawing explanation
Fig. 1 is the structural representation for the telescopic type steel die of making the large glass steel stack of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Embodiment: as shown in Figure 1, a kind of preparation method for the telescopic type steel die of making the large glass steel stack is characterized in that comprising the following steps:
The preparation of a, die main body
First, according to the dimensional requirement of chimney product, manage and inner frame preparing centre.By the inner frame welding on central tube.At skeleton outer cladding epidermis, epidermis can adopt the manganese plate that 3mm is thick.Cut open longitudinal seam at outer surface.Polish die surface until surface-brightening with sized flap wheel.
The preparation of b, stripper apparatus
Mould cut open seam inner two across between, retract cylinder is set, in mould ends, axial ejection cylinder is set.Need connect being rigidly connected between the inner frame that is placed in the shrinkage joint place during winding, when the needs demoulding, releasing is rigidly connected, retract and can realize the overall shrinkage of mould in the time of by the retract cylinder piston rod, mould and product section are broken away from, recycle axial oil cylinder ejecting product, product is thoroughly broken away from mould.After the final demoulding completes, in the time of by the retract cylinder piston rod, eject, realize the mold shape recovery, need after recovery again to be rigidly connected.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
