Description

Press plug type filling two-mold die

Technical Field

The utility model belongs to the technical field of the oil blanket mold processing, especially, relate to a pressure plug formula fills two division moulds of type, be applicable to the oil blanket that exposes skeleton needs upper and lower plane and only glue simultaneously, especially need the skeleton oil blanket that exposes of noble rubber production.

Background

The mold design of the exposed framework oil seal is generally an oil seal for stopping glue at the plane and the inclined plane at one side of the framework, and the simultaneous glue stopping of the upper plane and the lower plane of the framework is difficult to realize. When a common two-mold is used for production, rubber often overflows before a framework is pressed to be dead in the process of closing the mold, a middle mold needs to be added, the framework is pressed in advance by the middle mold to prevent rubber leakage, the flash of the mold is large for exhausting and adjusting excess materials, rubber materials are seriously wasted, the weight of a rubber blank needs to be reduced as much as possible in the production of an oil seal of precious metal rubber, the generation of waste materials is reduced, and the raw material cost caused by rubber leakage is not allowed.

Disclosure of Invention

An object of the utility model is to improve prior art not enough and provide one kind and can realize that the plane ends gluey, reduces the use of sizing material, the cost-effective pressure plug formula fills two division moulds of type about the skeleton simultaneously when two die sinking production.

The utility model aims at realizing like this, a two division moulds of pressure plug formula type of filling, including last mould, lower mould and lower core, its characteristics are that the center of going up the mould is equipped with the central through-hole of taking the boss, and the activity of pressing the stopper inlays the dress in the central through-hole, and spring clamp plate fixes at the top of pressing the stopper, and the upper surface of going up the mould is equipped with and spring clamp plate complex recess, and the recess inner ring is equipped with the spring of installing in the spring inslot around central through-hole, the upper end of spring and spring clamp plate's lower surface contact.

Compared with the prior art, the utility model has the following characteristics of showing and positive effect: the utility model discloses a mode of tamponade extrusion rubber realizes filling the type to be equipped with powerful spring and compress tightly the skeleton in advance, prevent to run gluey, the die cavity is full of the back, and powerful spring compresses tightly the mould, makes clout jack-up tamponade, realizes adjusting the function of clout. The utility model provides a current two die sinking realize about the skeleton plane only gluey production problem simultaneously, saved a template, also reduced the cost waste that runs glue and waste material produced, the oil blanket production of specially adapted noble rubber.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. the device comprises an upper die, 2, a spring, 3, a spring pressing plate, 4, a central through hole, 5, a press plug, 6, a lower die, 7, a framework, 8, a lower die core, 9, a rubber blank, 10 and a groove.

Detailed Description

The utility model provides a two division moulds of tamponade formula type of filling, refer to fig. 1, it is together that last mould 1, lower mould 6 and lower mold core 8 are installed according to conventional technique, skeleton 7 is placed in last mould 1 and lower mould 6 within a definite time, it forms the injecting glue die cavity that is used for forming the oil blanket rubber body to go up mould 1, lower mould 6 and lower mold core 8 within a definite time, the upper surface of lower mold core 8 is used for placing gluey embryo 9, the aforesaid is conventional technique, the center of going up mould 1 is equipped with central through-hole 4 of taking the boss, tamponade 5 activity inlays the dress and can not deviate from the top in central through-hole 4, spring clamp 3 fixes the top at tamponade 5, the upper surface of going up mould 1 is equipped with the recess 10 with spring clamp 3 complex, circle central through-hole 4 in recess 9 and be equipped with the.

Use the utility model discloses in the time, 2 elasticity of spring before the compound die bounce spring clamp plate 3 and tamponade 5, in the compound die pressurization process, outside template is exerted pressure to the higher spring clamp plate 3 that bounces, and spring 2 is compressed by spring clamp plate 3 and is produced pressure and transmit last mould 1, goes up mould 1 and compresses tightly skeleton 7 and lower mould 6, and the skeleton 7 is compressed tightly in advance from top to bottom, prevents the rubber outflow. Meanwhile, the spring pressing plate 3 drives the pressing plug 5 to move downwards, the rubber blank 9 below the pressing plug 5 is extruded into the cavity, after the cavity is filled with excess materials, the pressure of the cavity can jack the upper die 1 or the pressing plug 5, the upper die 1 is tightly pressed by the spring 2, the pressing plug 5 is tightly pressed by the template, when the pressure of the spring 2 is greater than the pressure of the external template, the pressing plug 5 is partially jacked to adjust the excess materials, and when the pressure of the external template is greater than the pressure of the spring 2, the upper die 1 is jacked up, and rubber leakage occurs.

Claims

1. The utility model provides a two division moulds of plug formula of pressing fills type, includes mould, lower mould and lower mould core, and characterized by goes up the center of mould and is equipped with the central through-hole of taking the boss, and the activity of pressing the stopper inlays the dress in the central through-hole, and spring clamp plate fixes at the top of pressing the stopper, and the upper surface of going up the mould is equipped with the recess with spring clamp plate complex, and the recess is interior to be equipped with around central through-hole and to install the spring in the spring inslot, the upper end of spring and spring clamp plate.
