Abstract
The utility model discloses a sealing adhesive device for double-color dies, which comprises a fixed seat, a lever, a flat ejector pin and a bracing pin, wherein the lever is rotatablely arranged on the fixed seat by a pin bolt and contacted with the fixed seat in a surface contact mode, one end of the lever is connected with the connecting end of the flat ejector pin, and the other end of the lever is connected with the connecting end of the bracing pin, the connecting end of the flat ejector pin is provided with a groove, the flat ejector pin and the lever are matched by the groove, and the outer side wall of the flat ejector pin is sleeved with a guide sleeve. In such a way, in a sealing adhesive device product, through contacting the lever with the fixed seat in a surface contact mode, the breaking of the pin bolt can be prevented, and the length of the flat ejector pin is fixed, thereby improving the operating efficiency and reducing the cost; because the flat ejector pin and the lever are matched by the groove, so that the contact area between the flat ejector pin and the level is increased, and the height of the flat ejector pin is not reduced after being used for a long time, thereby improving the sealing adhesive quality; and the outer side wall of the flat ejector pin is sleeved with a guide sleeve, so that the flat ejector pin is prevented from being damaged.
Description
Technical field
The utility model relates to a kind of sealing device, relates in particular to a kind of sealing device that is used for double color mould.
Background technology
At present, in double color mould, the sealing between the different colours is an important subject in the industry; Existing sealing device generally is made up of holder, lever, flat thimble and holder pin; Wherein, lever is installed in rotation on the holder through pin, and the two ends of lever contact with flat thimble, holder needlework respectively; Yet structurally there is following defective in existing this sealing device:
One, have bigger gap between lever and the holder, when second time injection moulding, injection pressure is applied on the pin fully; Might cause pin to fracture, thereby interrupt sealing, so not only reduce operating efficiency; But also improved cost, and the length of flat thimble also can't be confirmed; Also need adjust the length of flat thimble when causing matched moulds, bring operational loaded down with trivial detailsly, further reduce operating efficiency;
Two, be that line contacts between lever and the flat thimble, the time has been grown possible pressurized wearing and tearing, causes flat thimble to reduce, and the glue position of sealing place will be given prominence to like this, thereby has reduced the sealing quality;
Three, owing to be that swing through lever drives flat thimble and moves up and down, therefore flat thimble can be swung in motion process, and flat thimble will be impaired because of receiving side force.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of sealing device that is used for double color mould, and its high efficiency has reduced cost, has improved the sealing quality, and can protect flat thimble not impaired.
For realizing that above-mentioned purpose the utility model adopts following technical scheme:
A kind of sealing device that is used for double color mould comprises holder, lever, flat thimble and holder pin, and this lever is installed in rotation on the holder and with holder formation face through pin and contacts; One end of lever contacts with the link of flat thimble; The other end contact with the link of holder pin, and the link of flat thimble is provided with groove, and flat thimble passes through this groove and lever mated; And the lateral wall of said flat thimble also is socketed with fairlead.
A kind of sealing device that is used for double color mould that the utility model is set forth, its beneficial effect is:
One, this product is through contacting lever with holder formation face, and when second time injection moulding, injection pressure just is applied on the holder fully like this; The pin that can not fracture can carry out sealing continuously, thereby has improved operating efficiency; Reduced cost, and the distance from the top of lever to the glue position is exactly the length of flat thimble; This length is fixed, and need not to adjust flat thimble during matched moulds again, and this has further improved operating efficiency;
Two, this product is provided with groove through the link at flat thimble, makes flat thimble and lever through groove fit, has increased both contacts area, and the time has been grown flat thimble and also can not reduce like this, thereby has improved the sealing quality;
Three, this product protects flat thimble not impaired through the lateral wall socket fairlead at flat thimble.

The specific embodiment
Come the utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Please with reference to shown in Figure 1, it has demonstrated the concrete structure of the utility model preferred embodiment, a kind of sealing device that is used for double color mould; Comprise holder 10, lever 20, flat thimble 30 and holder pin 40, this lever 20 50 is installed in rotation on the holder 10 and with holder 10 formation faces and contacts through pinning, and an end of lever 20 contacts with the link of flat thimble 30; The other end contacts with the link of holder pin 40; And the link of flat thimble 30 is provided with groove 31, and flat thimble 30 cooperates with lever 20 through this groove 31, when lever 20 rotates; Flat thimble 30 will receive the thrust of lever 20 and move up or down; And the lateral wall of said flat thimble 30 also is socketed with fairlead 32, is used to prevent that flat thimble 30 from receiving excessive side force when moving.
The design focal point of the utility model is: at first, this product is through contacting lever 20 with holder 10 formation faces, like this when second time injection moulding; Injection pressure just is applied on the holder 10 fully, and the pin 50 that can not fracture can carry out sealing continuously; Thereby improve operating efficiency, reduced cost, and; Distance from the top of lever 20 to the glue position is exactly the length of flat thimble 30; This length is fixed, and need not to adjust flat thimble 30 during matched moulds again, and this has further improved operating efficiency; Secondly, this product is provided with groove 31 through the link at flat thimble 30, and flat thimble 30 is cooperated through groove 31 with lever 20, has increased both contacts area, and the time has been grown flat thimble 30 and also can not reduce like this, thereby has improved the sealing quality; And this product protects flat thimble 30 not impaired through the lateral wall socket fairlead 32 at flat thimble 30.
The above; It only is the utility model preferred embodiment; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
