Abstract
A sealing device for sealing dies on a vulcanization forming machine relates to a sealing device for sealing shock-isolating support forming dies on a rubber vulcanization forming machine, and can reduce micro-gaps in rubber organizations to a lower degree so as to improve the mechanical performances of rubber products. The vulcanization forming machine comprises an upper heating plate and a lower heating plate. The sealing device comprises an upper vacuum cover and a lower vacuum cover, wherein the upper vacuum cover is cylindrical, and a flange structure I for connecting an upper heat plate is arranged at the top surface of the upper vacuum cover; the lower vacuum cover comprises an upper cylindrical tube and an lower hexagonal tube, and a flange structure II for connecting a lower heat plate is arranged at the bottom surface of the hexagonal tube; the outer surface of the upper vacuum cover and the inner surface of the cylindrical tube at the upper part of the lower vacuum cover are connected by a movable sealing device; and a nozzle jet is arranged at any corner part of the hexagonal tube at the lower part of the lower vacuum cover. By combining the structures of the existing vulcanization forming machine and the existing shock-isolating support forming machine, the sealing device can be integrated with the existing processing links very conveniently.
Description
Technical field
The utility model relates to a kind of vacuum sealing device, relates 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 process can be different on mechanical performance, physicochemical property.But the manufactured goods of identical raw material, identical component, identical processing environment when in the identical environment for use of different altitude height, using, very big difference occurs, and are then pondered-over.Like some product of the utility model people, 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.
The utility model content
The utility model is to above problem, provides a kind of and can microgap in the rubber tissue be reduced to more low-levelly, and then is used for the locking device of sealed mold on the sulfidization molding machine of raising rubber manufactured goods mechanical performance.
The technical scheme of the utility model is: said sulfidization molding machine comprises hot plate and following hot plate, and said locking device comprises vacuum (-tight) housing and following vacuum (-tight) housing;
Said 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 said hexagonal tube bottom surface is provided with and is used to connect the flange arrangement two of hot plate down;
The said upward outer surface of vacuum (-tight) housing and the inner surface of following vacuum (-tight) housing top cylindrical drum are connected through dynamic sealing device;
Be provided with valve in said arbitrary bight of vacuum (-tight) housing bottom hexagonal tube down.
Said surface of going up the vacuum (-tight) housing bottom is provided with the groove that is used for chimeric sealing ring; Said dynamic sealing device comprises the L shaped sealing ring that is embedded in the said groove, and the galianconism of said L shaped sealing ring embeds in the said groove, said L shaped sealing ring long-armed towards last vacuum (-tight) housing end face.
Said long-armed end portion thickness is less than the thickness of said long-armed root, makes the long-armed wedge shape that is.
The utility model has been broken through the conventional process flow of traditional shock isolating pedestal processing, and when sulfidization molding, increase vacuumizes operation.The device of the utility model 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 is fixedly connected on respectively on hot plate and the following hot plate with following vacuum (-tight) housing, 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 utility model at first exceeds those skilled in the art and has found technical problem to be solved with expecting, and combines existing production line, has proposed exquisite technical scheme, and the final mechanical performance of products that processes that makes promotes significantly.

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 utility model is shown in Fig. 1-3: said sulfidization molding machine comprises hot plate 1 and following hot plate 4, and said locking device comprises vacuum (-tight) housing 2 and following vacuum (-tight) housing 3;
Said 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, said bottom are provided with and are used to connect the flange arrangement two of hot plate 4 down;
The said upward outer surface of vacuum (-tight) housing 2 and the inner surface of following vacuum (-tight) housing top cylindrical drum 31 are connected through dynamic sealing device;
Be provided with valve 5 at said 320 places, arbitrary bight of vacuum (-tight) housing bottom hexagonal tube 32 down.Be used to connect negative-pressure pipeline.
The said cylindrical outer surface of going up vacuum (-tight) housing 2 bottoms is provided with the groove that is used for chimeric sealing ring; Said dynamic sealing device comprises the L shaped sealing ring 23 that is embedded in the said groove, and the galianconism of said L shaped sealing ring 23 embeds in the said groove, said L shaped sealing ring 23 long-armed towards last vacuum (-tight) housing 2 end faces.Said long-armed end portion thickness is less than the thickness of said 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.
