Description

Peroxide material mold with good fluidity

Technical Field

The utility model belongs to the technical field of the peroxygen material mould and specifically relates to a better peroxygen material mould of mobility.

Background

The conventional rubber material uses a sulfur vulcanization system, and has good processing performance and high yield. For more demanding products, it is desirable to use a peroxide curing system. The peroxide vulcanization system has the defects of poor material flow property, thick burrs and no opening, large number of holes of the die and low productivity; there is also the problem of raw edges being difficult to handle, resulting in the problem of residual raw edges after normal conventional mold operation molding, which requires manual cutting or processing by a refrigerated burr machine, which is a very costly process. Insufficient exhaust is easy to occur in the conventional die, and poor air inclusion of the exhaust is caused. Therefore, it is necessary to design a peroxide material mold with better fluidity.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, a peroxide material mold with better fluidity is provided.

The utility model discloses a following scheme realizes:

the utility model provides a better peroxide material mould of mobility, includes the mould bottom plate the middle part correspondence of mould bottom plate is equipped with the finished product district the correspondence is equipped with a plurality of die cavities in the finished product district correspond between the die cavity and be equipped with a plurality of exhaust ditch, the outside correspondence in finished product district is equipped with the pressure boost ring the correspondence is equipped with a plurality of pressure boosts and flash ring in the finished product district still correspond in the finished product district and be equipped with a plurality of increases cutting nozzle ditches.

The mould is characterized in that the cavities are uniformly distributed on the upper surface of the mould base plate, a plurality of exhaust grooves are correspondingly arranged among the cavities, and the outer ends of the exhaust grooves extend out of the side wall of the mould base plate to be communicated with the outside.

The upper surface of the die bottom plate is correspondingly provided with eight rows and nine columns of cavities, the outer side of each cavity is correspondingly provided with an enlarged cutting nozzle groove, an exhaust groove is correspondingly arranged between every two rows of cavities, the outer side of every two rows of cavities is correspondingly provided with a circle of pressurizing and flash rings, the exhaust groove penetrates through the two adjacent pressurizing and flash rings, and the two ends of the exhaust groove are respectively communicated with the outside.

The booster ring is of a ring groove-shaped structure which is recessed downwards.

The enlarged cutting nozzle groove is of a ring groove-shaped structure recessed downwards.

The utility model has the advantages that:

the utility model relates to a better peroxide material mould of mobility can improve sizing material flow property, and then solves deckle edge problem, can also reduce the defective rate.

Drawings

Fig. 1 is a schematic structural view of a peroxide material mold with better fluidity according to the present invention;

FIG. 2 is a schematic view of a partial cross-sectional view of a peroxide mold with better flowability according to the present invention;

in the figure: 1 is a bottom plate, 2 is a cavity, 3 is an exhaust groove, 4 is a finished product area, 5 is a pressurizing ring, 6 is a pressurizing and material overflowing ring, and 7 is an enlarged cutting nozzle groove.

Detailed Description

The preferred embodiments of the present invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1 and 2, a better peroxide material mould of mobility, includes mould bottom plate 1 the middle part correspondence of mould bottom plate 1 is equipped with finished product district 4 the correspondence is equipped with a plurality of die cavities 2 in the finished product district 4 the correspondence is equipped with a plurality of exhaust ditch 3 between the die cavity 2, the outside correspondence of finished product district 4 is equipped with pressure boost ring 5 the correspondence is equipped with a plurality of pressure boosts and flash ring 6 in the finished product district 4 still the correspondence is equipped with a plurality of nozzle cutting ditches 7 that increase in the finished product district 4.

The die cavities 2 are uniformly distributed on the upper surface of the die bottom plate 1, a plurality of exhaust grooves 3 are correspondingly arranged between the die cavities 2, and the outer ends of the exhaust grooves 3 extend out of the side wall of the die bottom plate 1 to be communicated with the outside. An exhaust channel 3 is added, the exhaust problem in the production process is improved, and bad air inclusion is reduced.

The upper surface of mould bottom plate 1 corresponds to be equipped with the die cavity 2 of eight rows nine rows the outside of every die cavity 2 all corresponds and is equipped with and increases cutting nozzle ditch 7 correspond between every two rows of die cavities 2 and is equipped with an exhaust ditch 3 the outside of every two rows of die cavities 2 all corresponds and is equipped with round pressure boost and flash ring 6, exhaust ditch 3 passes between two adjacent pressure boost and flash ring 6, and the both ends of exhaust ditch 3 communicate with the external world respectively. This application falls the face near die cavity edge region, forms pressure boost and flash ring 6, except playing the effect pressure boost of pressure boost ring 5, can also reach to fill the unnecessary sizing material of die cavity and can overflow this region, because this region falls the face and forms the cavity sizing material and not receive the pressure, so mobility is fine, reaches the problem of the thin deckle edge thickness of pressure, and then improves and remains the deckle edge problem.

The booster ring 5 is a ring groove-shaped structure which is recessed downwards. And lowering the surface in the area outside the finished product area to reduce the pressure bearing surface to form a pressure increasing ring 5, so that the relative pressure is increased, and the number of die opening holes of the die can be increased. The enlarged cutting nozzle groove 7 is a ring groove structure recessed downwards. The enlarged cutting mouth groove 7 on the edge of the cavity can improve the flowing property of the sizing material, thereby solving the problem of rough edges.

The specific forming process, the supporting equipment, the principle and the method of the mold are known technologies, and are not described in detail herein.

Although the invention has been shown and described in detail with respect to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
