Abstract
The utility model belongs to the technical field of a die of a rubber gasket and discloses a production die for a large-size rubber sealing gasket. The production die for the large-size rubber sealing gasket is mainly and technically characterized by comprising a die chassis and a die cover; a lower cavity groove and an upper cavity groove are respectively arranged on the opposite faces of the die chassis and the die cover; a die inner cavity is defined by the lower cavity groove and the upper cavity groove; and the die inner cavity is in a circular arc shape. A section of a circular arc is taken as the die inner cavity according to a diameter size of the large-size sealing gasket in need of machining, and is vulcanized section by section by using a continuous vulcanizing method; and the both ends of a joint part are in butt joint with the die for vulcanizing, so as to form the entire large-size rubber sealing gasket. The production die has the characteristics of convenience in use, low production cost, light weight and high production efficiency.
Description
Technical field
The utility model belongs to the rubber cushion technical field of mold, relates to concretely a kind of large-scale rubber gasket production mould.
Background technology
In the fields such as chemical industry, the vacuum reaction still is widely used.Most vacuum reaction stills adopt solid rubber sealing gasket or the sealing of hollow rubber sealing gasket.Sulfurizing mould with circular cavity in the middle of the small-sized sealing pad adopts mostly vulcanizes, but for the large sealing pad more than 1 meter, if adopt large-scale sulfurizing mould to have following defective: one, mould is large, and the Mould Machining difficulty is large, and Die price is high; Its two, die area is large, same area of dissipation is also large, in process of production, energy waste is serious; Its three, mold weight is large, molding need to be by special-purpose machinery, production cost is high.
The utility model content
The technical problem that the utility model solves just provides a kind of easy to use, production cost is low, lightweight, production efficiency is high large-scale rubber gasket production mould.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise mould chassis and die cover, on described mould chassis and die cover opposite face cavity of resorption groove and epicoele groove are set respectively, described cavity of resorption groove and epicoele groove surround dies cavity, and described dies cavity is circular arc.
Its additional technical feature is:
The cross sectional shape of described dies cavity is circle, ellipse, square, rectangle, triangle or trapezoidal.
The large-scale rubber gasket production mould that the utility model provides, compare with prior art and to have the following advantages: one, owing to comprising mould chassis and die cover, on described mould chassis and die cover opposite face cavity of resorption groove and epicoele groove are set respectively, described cavity of resorption groove and epicoele groove surround dies cavity, described dies cavity is circular arc, the diameter of the large sealing pad of processing as required, get wherein one section circular arc as dies cavity, then adopt the way length-to-length cure of the sulfuration that continues, then the two ends of blank area are docked in the mould and vulcanize, form whole large sealing pad, this production mould is easy to use, production cost is low, lightweight, the characteristics that production efficiency is high; Its two because the cross sectional shape of described dies cavity is circle, ellipse, square, rectangle, triangle or trapezoidal, produce conveniently, the sealing effectiveness of large sealing pad is better.

The specific embodiment
The structure of the large-scale rubber gasket production mould that the utility model is proposed below in conjunction with accompanying drawing is described further.
As depicted in figs. 1 and 2, be the structural representation of large-scale rubber gasket production mould.Its structure comprises mould chassis 1 and die cover 2, on mould chassis 1 and die cover 2 opposite faces cavity of resorption groove 3 and epicoele groove 4 is set respectively, and cavity of resorption groove 3 and epicoele groove 4 surround dies cavity 5, and dies cavity 5 is circular arc.Like this, the diameter of the large sealing pad of processing as required, get wherein one section circular arc as dies cavity 5, then adopt the way length-to-length cure of the sulfuration that continues, then the two ends of blank area are docked in the mould and vulcanize, form whole large sealing pad, the characteristics that this production mould is easy to use, production cost is low, lightweight, production efficiency is high.
The cross sectional shape of dies cavity 5 can be as shown in Figure 2 circle; Certainly the cross sectional shape of dies cavity 5 also can be square as shown in Figure 3; It also can be rectangle as shown in Figure 4; It also can be ellipse as shown in Figure 5; It also can be triangle as shown in Figure 6; Can also be as shown in Figure 7 trapezoidal, produce conveniently, the sealing effectiveness of large sealing pad be better.
This mould can be used for producing the large-scale solid rubber gasket, also can be used for producing the hollow seal pad, adds core again and get final product when producing the hollow seal pad.
Protection domain of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the large-scale rubber gasket production mould of the utility model structure, just drops on the scope of the utility model protection.
