Abstract
The utility model discloses a kind of hot pressing graphite jig, comprise upper die and lower die, transmission mechanism and heating tube, described counterdie die cavity is disk, some equally distributed circular holes are provided with in disk, counterdie plunger tip is placed in circular hole, patrix die cavity is provided with the disk and circular hole that match with counterdie die cavity, is connected bottom plunger tip with transmission mechanism, and top is corresponding with upper film die cavity circular hole.The utility model structure is simple, and ejected by product by core rod, originally a secondary mould can only do the product of 100,000, and after improvement one secondary mould can accomplish more than 1,200,000 products, and production scene does not have unnecessary powdered graphite, and usefulness greatly increases.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of hot pressing graphite jig, manufactures for seal.
Background technology
The main movable ring part of seal product of current production is graphite, and graphite powder is moulded shaping by graphite jig by it.Product is ejected by the top cylinder under mould cavity or plunger tip by traditional graphite after processing, but with top cylinder, product is ejected, top cylinder cylindrical and die cavity inner circle, top cylinder inner circle and the friction of core rod cylindrical are seriously, need to change core rod, top cylinder and die cavity, this just makes die life short, affects operating efficiency.Directly ejected by product with core rod, die life is slightly longer, but dust problem is difficult to solve, and production scene dust is boundless and indistinct, and affect employee's health strong, and die change heating tube is cumbersome, dismounting upper and lower mould to change.
Utility model content
The utility model is for the problems referred to above, provide a kind of hot pressing graphite jig, direct employing disc die cavity graphite thermal compression mould, baiting method no longer adopts two circle dislocation blanking methods or a circle push-and-pull blanking method, disc die cavity put into by the direct good raw material of dosing container amount passing through calculating that adopts, and all raw materials and product are all shaping in die cavity, and raw material redundance is hot pressed into product overlap, there is no dust from flying, increase work efficiency.Do not need dismounting upper and lower mould when changing heating tube, directly heating tube is extracted out or loaded onto from upper and lower mould bottoming hole and then can.
Technical solution of the present utility model:
A kind of hot pressing graphite jig, comprise upper die and lower die, transmission mechanism and heating tube, it is characterized in that: described counterdie die cavity is disk, some equally distributed circular holes are provided with in disk, counterdie plunger tip is placed in circular hole, described patrix die cavity is provided with the disk and circular hole that match with counterdie die cavity, is connected bottom described plunger tip with transmission mechanism, and top is corresponding with upper film die cavity circular hole.
Described counterdie offers through hole, and heating tube is placed in through hole.
Described upper film offers through hole, and heating tube is placed in through hole.
The beneficial effects of the utility model:
The utility model structure is simple, and ejected by product by core rod, originally a secondary mould can only do the product of 100,000, and after improvement one secondary mould can accomplish more than 1,200,000 products, and production scene does not have unnecessary powdered graphite, and usefulness greatly increases.
Accompanying drawing explanation
Fig. 1 is the utility model lower mode cavity structural representation.
Fig. 2 is the utility model upper cavity structural representation.
Fig. 3 is graphite jig structural representation.
In figure: 1, cope match-plate pattern, 2, lower bolster, 3, through hole, 4, plunger tip, 5, upper cavity, 6, lower mode cavity, 7, lower mode cavity circular hole, 8, upper cavity circular hole.
Detailed description of the invention
The utility model is illustrated below in conjunction with drawings and Examples:
As shown in Figure 1 to Figure 3, hot pressing graphite jig, comprise cope match-plate pattern 1, lower bolster 2, transmission mechanism and heating tube, cope match-plate pattern and lower bolster all offer through hole 3, heating tube is placed in through hole 3, wherein, lower mode cavity 6 is disk, is provided with some equally distributed lower mode cavity circular holes 7 in disk, counterdie plunger tip 4 is placed in lower mode cavity circular hole 7, upper cavity 5 is provided with the disk and circular hole that match with lower mode cavity 6, is connected bottom plunger tip 4 with transmission mechanism, and top is corresponding with upper film chamber circular hole 8.
Specific works engineering:
As shown in Figure 2, pour in disc lower mode cavity 6 by the good graphite powder of dosing container amount, cope match-plate pattern 1 presses down that to carry out hot pressing moulding, match with upper cavity circular hole 8 in plunger tip 4 upper end, graphite powder is evenly distributed in disk under the effect of cope match-plate pattern pressure that to carry out row integral heat pressure shaping, and the circular hole produced around plunger tip is product.
After product is hot-forming, cope match-plate pattern moves, product ejects by plunger tip, is taken out by product by feeding plate.This kind of method raw material redundance all overall thermal is pressed into product overlap, does not have dust to fly out, greatly improves working environment, heating tube is directly inserted in through-holes simultaneously, be not placed in upper die and lower die inside, when needing to change, directly heating tube extracted out or loaded onto from upper and lower mould bottoming hole and then can.
Claims (3)
