Abstract
The invention relates to a sealing device for sealing a die on a vulcanization forming machine, in particular to a sealing device for sealing a vibration isolation support forming die on rubber vulcanization equipment. By the vulcanization forming machine, microgaps in rubber tissue can be reduced to a low level to improve the mechanical performance of rubber products. The vulcanization forming machine comprises an upper heat plate and a lower heat plate; the sealing device comprises an upper vacuum cover and a lower vacuum cover, wherein the upper vacuum cover is in a cylindrical shape; a flange structure I which is connected with the upper heat plate is arranged on the top surface of the upper vacuum cover; the lower vacuum cover comprises a cylinder on the upper part and a hexagonal cylinder on the lower part; a flange structure II which is connected with the lower heat plate is arranged on the bottom surface of the hexagonal cylinder; the outer surface of the upper vacuum cover is connected with the inner surface of the cylinder on the upper part of the lower vacuum cover by a movable sealing device; and an air nozzle is formed at any one corner part of the hexagonal cylinder on the lower part of the lower vacuum cover. The sealing device can be merged into the conventional machining link conveniently by combining the conventional vulcanization forming machine and a structure of the vibration isolation support forming die.
Description
Technical field
The present invention relates to a kind of vacuum sealing device, relate in particular to the locking device that is used to seal the shock isolating pedestal mould on the rubber curing forming equipment.
Background technology
Along with rubber develops towards the precision direction, production technology in the past can not satisfy the demand of high-end user now.At present, many high-end users not only are in the requirement to the rubber self character for the rubber as structural member, also have the requirement to mechanical performance, physicochemical property.
Can understand the like products that different raw materials, different components, different processing environments make can be different on mechanical performance, physicochemical property.But the manufactured goods of identical raw material, identical component, identical processing environment when using, very big difference occurs in the identical environment for use of different altitude height, then pondered-over.As some product of the inventor, try out when the plateau, find that there is undesired variation in mechanical performance of products.Trace it to its cause, we find it is because the microgap in the rubber tissue expands in the low pressure area, cause mechanical performance to reduce.
Summary of the invention
The present invention is directed to above problem, provide a kind of and microgap in the rubber tissue can be reduced to more low-levelly, and then improve the locking device that is used for sealed mold on the sulfidization molding machine of rubber manufactured goods mechanical performance.
Technical scheme of the present invention is: described sulfidization molding machine comprises hot plate and following hot plate, and described locking device comprises vacuum (-tight) housing and following vacuum (-tight) housing;
Described upward vacuum (-tight) housing is cylindrical, and the end face of last vacuum (-tight) housing is provided with the flange arrangement one that is used to connect hot plate;
Following vacuum (-tight) housing comprises top cylindrical drum and bottom hexagonal tube, and described hexagonal tube bottom surface is provided with and is used to connect the flange arrangement two of hot plate down;
The described upward outer surface of vacuum (-tight) housing and the inner surface of following vacuum (-tight) housing top cylindrical drum are connected by dynamic sealing device;
Be provided with valve in described arbitrary bight of vacuum (-tight) housing bottom hexagonal tube down.
Described surface of going up the vacuum (-tight) housing bottom is provided with the groove that is used for chimeric sealing ring; Described dynamic sealing device comprises the L shaped sealing ring that is embedded in the described groove, and the galianconism of described L shaped sealing ring embeds in the described groove, described L shaped sealing ring long-armed towards last vacuum (-tight) housing end face.
Described long-armed end portion thickness is less than the thickness of described long-armed root, makes the long-armed wedge shape that is.
The present invention has broken through the conventional process flow of traditional shock isolating pedestal processing, and when sulfidization molding, increase vacuumizes operation.Device of the present invention in conjunction with the structure of existing sulfidization molding machine, shock isolating pedestal mould, can incorporate easily in the existing processing link and go.Last vacuum (-tight) housing and following vacuum (-tight) housing are fixedly connected on respectively on hot plate and the following hot plate, and the cavity between two covers is large enough to hold the shock isolating pedestal mould, and does not stay excessive space, vacuumizes effect in order to avoid reduce; When keeping aforementioned effect, hexagon is arranged in the bottom of following vacuum (-tight) housing, such six angles have been reserved the space of lifting mould (2-4 hanger being arranged such as mould outward) hanger; Simultaneously, also reserved at least one the position of valve can be set.The present invention at first exceeds those skilled in the art and has found technical problem to be solved with expecting, and in conjunction with existing production line, has proposed exquisite technical scheme, and the final mechanical performance of products that processes that makes promotes significantly.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is an A-A cutaway view among Fig. 1,
Fig. 3 is a M place partial enlarged drawing among Fig. 1,
1 is to go up hot plate, the 2nd, last vacuum (-tight) housing, the 23rd, L shaped sealing ring, the 3rd, following vacuum (-tight) housing, the 31st, top cylindrical drum, the 32nd, bottom hexagonal tube, the 320th, bight, the 4th, following hot plate, the 5th, valve, the 6th, mould among the figure.
The specific embodiment
The present invention is as Figure 1-3: described sulfidization molding machine comprises hot plate 1 and following hot plate 4, and described locking device comprises vacuum (-tight) housing 2 and following vacuum (-tight) housing 3;
Described upward vacuum (-tight) housing 2 is cylindrical, and the end face of last vacuum (-tight) housing 2 is provided with the flange arrangement one that is used to connect hot plate 1;
Following vacuum (-tight) housing 3 comprises top cylindrical drum 31 and bottom hexagonal tube 32, and hexagonal tube 32 bottom surfaces, described bottom are provided with and are used to connect the flange arrangement two of hot plate 4 down;
The described upward outer surface of vacuum (-tight) housing 2 and the inner surface of following vacuum (-tight) housing top cylindrical drum 31 are connected by dynamic sealing device;
Be provided with valve 5 at described 320 places, arbitrary bight of vacuum (-tight) housing bottom hexagonal tube 32 down.Be used to connect negative-pressure pipeline.
The described cylindrical outer surface of going up vacuum (-tight) housing 2 bottoms is provided with the groove that is used for chimeric sealing ring; Described dynamic sealing device comprises the L shaped sealing ring 23 that is embedded in the described groove, and the galianconism of described L shaped sealing ring 23 embeds in the described groove, described L shaped sealing ring 23 long-armed towards last vacuum (-tight) housing 2 end faces.Described long-armed end portion thickness is less than the thickness of described long-armed root, makes the long-armed wedge shape that is.This version is in order to realize movable sealing better, and when external pressure during greater than inside, because the long-armed inclined wedge-shaped that is, preferential version is the inclined-plane of roof pressure wedge, promptly realizes sealing.Adopt two L shaped sealing ring better effects if.
The present invention can be according to the different desired heights of regulating automatically of mould 6 height.The outside suction air of vavuum pump, it is minimum that air gap is reduced to, the quality of assurance product.
