Description
Technical field
The utility model relates to cushion rubber manufacturing technology field, relates to or rather a kind of cushion rubber pickoff.
Background technology
In the connection of pipe fitting connection or other parts, conventionally use cushion rubber, cushion rubber can play sealing and make to connect effect more closely.Conventionally adopt now mould pressing method to manufacture cushion rubber, adhesive tape is put in the die cavity of particular manufacturing craft, adopt mould pressing method moulding.The factor such as viscosity and the shape of cushion rubber itself having due to the effect of being squeezed in forming process, cushion rubber material, cushion rubber after moulding all can be attached on mould, need to adopt special purpose device or manually cushion rubber be taken off, this not only can make mould structure complexity or increase manpower work, and has increased widely cost and reduced production efficiency.
Summary of the invention
The purpose of this utility model is, provide a kind of can automatic demoulding, cushion rubber pickoff simple in structure.
To achieve these goals, the technical solution adopted in the utility model is: a kind of cushion rubber pickoff, comprise upper die and lower die, counterdie relatively patrix moves up and down, counterdie has the die cavity of annular, die cavity bottom is provided with compacted under groove, it is characterized in that, patrix is provided with core rod, core rod can be under himself Action of Gravity Field relatively patrix freely move down, core rod has at the pressing part of lower end with at the stop part of upper end, shape and the die cavity of pressing part are suitable, can be pressed in die cavity, stop part is used for preventing that core rod is separated from patrix, patrix has upper forming tank, upper forming tank is above described pressing part, can be pressed on pressing part, the top of shape and pressing part is suitable.
In such scheme, after cushion rubber compression molding, be attached on core rod, in the process moving down at counterdie, core rod is because the relative patrix of himself gravity moves down, move down after a segment distance, the cut because stop part is subject to stopping of patrix, under vibration and effect of inertia, cushion rubber automatic trip leaves core rod.The utility model utilizes the structure of mould itself to reach the object of automatic demoulding, and structure is very simple.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the utility model cushion rubber pickoff.
Below in conjunction with accompanying drawing, the utility model is described in detail.
The specific embodiment
Referring to Fig. 1, cushion rubber pickoff comprises counterdie 1 and patrix 2, and counterdie 1 is under patrix 2, and patrix 2 moves up and down relatively.Counterdie 1 has the die cavity 11 of the annular of opening upwards, and the bottom of die cavity 11 is provided with compacted under groove 12.Patrix 2 is provided with core rod 3, and the middle and upper part of core rod 3 is in the through hole of patrix 2, and core rod 3 has gap with this through hole, core rod 3 can be under himself Action of Gravity Field relatively patrix 2 freely move down.Core rod 3 has the stop part 32 in upper end, and stop part 32 is one, and to the annulus radially protruding, its diameter is greater than the diameter of the bottom of the through hole in patrix 2, and stop part 32 is mainly used in preventing that core rod 3 is separated from patrix 2.In the time of the compressing rear demoulding of cushion rubber, counterdie 1 moves down, core rod 3 under himself Action of Gravity Field relatively patrix 2 freely move down, when moving down after a segment distance, stop part 32 is subject to stopping of patrix 2 and stops moving down, and under vibration and effect of inertia, cushion rubber automatic trip leaves core rod.Core rod 3 also has the pressing part 31 in lower end, and the shape of pressing part 31 and die cavity 11 are suitable, can be pressed in die cavity 11.Patrix 2 has upper forming tank 21, and upper forming tank 21, above pressing part 31, can be pressed on pressing part 31, and the top of shape and pressing part 31 is suitable.Pressing part 31 matches with upper forming tank 21 and compacted under groove 12 respectively, suppresses respectively two limits up and down of cushion rubber 5, and the shape of pressing part 31, upper forming tank 21 and compacted under groove 12 is according to the shape design of cushion rubber.The material of core rod 3 preferably adopts bearing steel, and its weight and size are determined according to structure and the size of manufacturing cushion rubber, again can automatic demoulding as long as can suppress cushion rubber.
Core rod 3 is provided with locating hole 33, and locating hole 33 is the bellmouth coaxial with core rod 3.Correspondingly, counterdie 1 is provided with locating dowel 13, and locating dowel 13 is a taper round platform coaxial with die cavity 11, and locating dowel 13 can be inserted in locating hole 33, and shape and locating hole 33 are suitable.Counterdie 1 and core rod 3 coordinates by locating dowel 13 and locating hole 33, completes location.
Cushion rubber pickoff has multiple counterdies that cooperatively interact 1, patrix 2 and core rod 3, can once suppress multiple cushion rubbers, further enhances productivity.
Below in conjunction with the course of work of Brief Description Of Drawings the utility model cushion rubber pickoff.First be blowing, film blank material is placed in die cavity 11, film plaster leans against in the outside wall surface of die cavity 11, and the bottom of film covers on compacted under groove 12; Then be moulding, the relative patrix 2 of counterdie 1 moves up, and core rod 3 is first pressed in die cavity 11, on continuing, moves until matched moulds counterdie 1, pressing part 31 matches with upper forming tank 21 and compacted under groove 12 respectively, suppresses respectively two limits up and down of cushion rubber 5, moulding cushion rubber 5 be attached on pressing part 31; Be finally the demoulding, counterdie 1 moves down, and core rod 3 moves down under himself Action of Gravity Field, moves down after a segment distance, and because stop part 32 is subject to stopping and cut of patrix 2, under vibration and effect of inertia, cushion rubber 5 automatic trips leave core rod 3.The utility model utilizes the gravity of core rod self to carry out automatic demoulding, and structure is very simple.
