Abstract
The utility model discloses a vulcanizing mould for rubber hoses, which comprises a core rod which is used for penetrating through a rubber hose billet, and at least further comprises a cap which is used for matching with the core rod, wherein the cap has a round sleeve structure, the inner wall of the round sleeve structure is provided with a first diameter and a second diameter, wherein the first diameter has the size of accommodating the core rod which penetrates through the rubber hose billet, and the second diameter has the size of only accommodating the core rod which penetrates through the rubber hose billet. Because the cutting procedure is eliminated, the two end stub bars are reduced, accordingly, the production efficiency is improved, the cost is reduced, the production efficiency of the existing technology is 1.5 times of the original technology, the two end stub bars are reduced, and the one-time input yield is improved by 8-10%. After the technological design is adopted, the cost is reduced by about 8% compared with the original technological design, the product size is stable, the performance is reliable, and the efficiency is high.
Description
Technical field
The utility model relates to the auto parts machinery field, specifically is a kind of rubber tube sulfurizing mould that auto parts and components are used of producing.
Background technology
Automobile is made up of many parts, according to each parts functional performance and product performance, needs difform special hose to connect.
Automobile Design comprises chassis, engine, radiator, interior trim etc., and the engine surrounding space is little, and in order to guarantee interconnecting of positions such as engine, radiator, fuel tank, main engine plants' design adopts special-shaped rubber tube to connect usually.Size, spatial form and the product function performance of special-shaped rubber tube are particularly important, if special-shaped rubber tube internal diameter, external diameter or wall thickness dimension control are inhomogeneous, and the risk that leakage of oil is arranged when being connected with other parts or leak, weight person burns engine.Because rubber is macromolecular elastomer, elastomeric material has good springiness, the characteristics that swell increment is big, and controlling the stable uniformity that reaches of internal diameter, external diameter and wall thickness dimension in extrusion has certain difficulty, product percent of pass is usually 95%, and the two ends stub bar accounts for the 8-10% of shape tube weight.Common special-shaped rubber tube production technology is come the extruding pipe embryo by extruder after adopting the sizing material banburying good, wears the mould sulfuration with the swage tool then, and the pipe after the sulfuration cleans, and carries out the two ends cutting again.
The utility model content
Along with the development that automobile industry is advanced by leaps and bounds, the rising steadily of oil price, also in various degree the rise of many raw material relevant with oil, as: ethylene propylene diene rubber, ethylene-acrylate rubber, carbon black, yarn, paraffin oil, vulcanizing agent and promoter.Main engine plants reduce the car load price one after another in order to extend volume growth, thereby partial pressure is married again on one's body the supplier.Auto parts and components supplier is in order to tackle main engine plants' price reduction in every year, the continuous increase of raw-material continuous rise in price and cost of labor, and many suppliers are from promoting internal control, and energy-conservation taping the latent power cuts the waste, and reduces cost stabilized product quality.The components supplying merchant updates and promotes, and the market competition that is not growing more intense is eliminated.
Technical problem to be solved in the utility model is: a kind of low cost, the special-shaped rubber tube of high efficiency low pressure are provided.
For solving the problems of the technologies described above, the utility model provides a kind of rubber tube sulfurizing mould, described sulfurizing mould mainly comprises the plug that is used to pass the rubber tube pipe, it is characterized in that: described sulfurizing mould comprises that also at least one is used for the cap that cooperates with described plug, described cap is the circular sleeve structure, the inwall of described circular sleeve structure is a terraced structure, described terraced structure has first diameter and second diameter, wherein said first diameter has the size that can hold the plug that passes rubber tube pipe state, and described second diameter has the size that only can hold the plug that does not pass rubber tube pipe state.
Wherein, described sleeve removably cooperates installation with described plug.
Wherein, described cap also comprises lid, and described covering is provided with some pores.
The rubber tube that adopts above-mentioned rubber tube sulfurizing mould to produce, it is from inside to outside for comprising ethylene-propylene-diene monomer glue-line, knitted layer and ethylene-propylene-diene monomer glue-line successively.
In process of production, sizing compound formula is suitably adjusted, the Mooney and the time of scorch of control sizing material, sizing material produces bin cure when preventing to attach the names of pre-determined candidates sulfuration.
The utility model compared with prior art has the following advantages:
1, improve sizing compound formula, improved the Mooney viscosity of sizing material, it is good to be convenient in the sulfidation rubber mobility, and expanding, it is little to change.Improved the security of sizing material, sizing material is difficult for incipient scorch in the operating process;
2, mould increases cap, according to the link position between sizing material expansion rate and pipe and other parts, and the degree of depth and the internal diameter size of design cap, thereby the external diameter and the wall thickness dimension of assurance pipe;
3, after every mould changes into and attaching the names of pre-determined candidates, reduced the cutting action of two ends stub bars, and saved stub bar, significantly reduced material cost, the cost of raw material and cost of labor can save about 12%.Not only improve production efficiency, reduced material cost again simultaneously, constant product quality, performance is not affected, and has bigger competitiveness in the same industry.

Fig. 2 a is the vertical view of Fig. 1;
Fig. 2 b is along the profile of B-B line among Fig. 2 a;
Fig. 3 is the schematic diagram of rubber tube in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Referring to Fig. 1, Fig. 1 shows the cap 1 that is used with the plug (not shown) in the rubber tube sulfurizing mould, and wherein plug can be arranged to different shape and size as required, thereby can produce corresponding special-shaped rubber tube.Cap 1 is arranged to the circular sleeve structure, and it includes and covers 2, and lid 2 is provided with some pores 4 and handle 3.Referring to Fig. 2 a-2b, the inwall of the circular sleeve structure of cap 1 has terraced structure, this terraced structure has first diameter 6 and second diameter 5 (only showing radius among Fig. 2 b), wherein first diameter 6 has the size that can hold the plug that passes rubber tube pipe state, and second diameter 5 has the size that only can hold the plug that does not pass rubber tube pipe state.
When producing rubber tube, can cap 1 be installed in the one or both ends of plug, entering the sulfuration program, when pipe when vulcanizing deformation takes place, because the positioning action of cap, make that the end of the rubber tube after vulcanizing is smooth, can guarantee that size and dimension reaches requirement, in addition since product need not the cutting, cancelled cutting action, provided cost savings.
Referring to Fig. 3, the rubber tube that adopts this rubber tube sulfurizing mould to produce, it comprises ethylene-propylene-diene monomer glue-line 7, knitted layer 8 and ethylene-propylene-diene monomer glue-line 9.
In addition, the manufacturing process of the special-shaped rubber tube used of the utility model auto parts and components is:
1. ethylene propylene diene rubber is prepared burden in proportion;
2. sizing material is mediated and is made the semi-finished product sizing material with banbury;
