Description
Technical field
The present invention relates to a kind of stripper apparatus, particularly relate to a kind of press stripper apparatus.
Background technology
What adopt during the current demoulding is the push rods of two square bars as transmission of pressure, and one end of push rod is placed on above mould, and press is pressed in the other end of push rod, thus realizes the demoulding; During work, must by one man operation press, another people holds up two push rod demouldings, there is great potential safety hazard, and needs two people's operations, waste of manpower; In addition, push rod cannot stretch, and thus needs the push rod making differing heights, causes the serious wasting of resources.
Summary of the invention
The invention provides a kind of press stripper apparatus, when being intended to solve the press demoulding in prior art, there is the problem of larger potential safety hazard in two push rods that need people to hold up.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of press stripper apparatus, comprise be positioned at press top pressure head, be positioned at press bottom and workbench for supporting workpiece and mold assemblies, also comprise at least two push rods for the demoulding, described each push rod is all arranged on the upper end of mould by the magnetic stand being arranged on its underpart.
Further, described mould comprises urceolus, installs inner core on the table, between urceolus and inner core upper end cope match-plate pattern, between urceolus and inner core lower end and the lower bolster installed on the table, described push rod is evenly arranged on the upper end of urceolus, and the diameter of push rod is less than the wall thickness of urceolus; The diameter of push rod is less than the wall thickness of urceolus, makes push rod be pressed onto cope match-plate pattern, is convenient to push rod and urceolus pressure is fallen, realize the demoulding.
Further, described workbench comprises the base plate being connected in press bottom, is connected in the annulus of plate upper surface, is fixed on base plate in the centre bore that described inner core is inserted in annulus, described lower bolster is fixed on the upper surface of annulus, and the external diameter of described annulus is less than the external diameter of lower bolster; Inner core and lower bolster are fixed by workbench, and the external diameter of annulus is less than the external diameter of lower bolster, make urceolus encounter workbench, are conducive to urceolus to press smoothly.
Further, the lateral wall of described push rod extends the block suitable with urceolus lateral wall downwards vertically; Block is convenient to the location of push rod, prevents push rod to be pressed on cope match-plate pattern.
Further, described push rod has three and is evenly distributed on mould circumferentially; Very little, bearing pressure can be comparatively large, there is the hidden danger fractureed for push rod quantity; Push rod quantity is too many, can cause each push rod discontinuity, thus can cause the distortion of mould and workpiece.
Further, described each push rod upper end is equipped with push rod screwed hole, and in described each push rod screwed hole, all switching has one section of extension bar; Be convenient to, according to the different length needing to adjust push rod, save resource and cost.
Further, the upper end described each push rod being positioned at push rod screwed hole is equipped with unthreaded hole, straight screw sleeve is provided with in described unthreaded hole, the screwed hole of centre of described straight screw sleeve and push rod screwed hole form the screwed hole matched with the threaded portion of extension bar jointly, and described straight screw sleeve is connected on push rod by trip bolt; By the fastening straight screw sleeve of trip bolt, can effectively prevent extension bar from taking a turn for the worse.
Compared with prior art advantage of the present invention is: in the present invention, the lower end of each push rod is equipped with magnetic stand, be easy to realize the fixing of push rod and dismounting by the switch of rotation magnetic force gauge stand, magnetic force is adopted push rod to be fixed on mould upper end, the huge potential safety hazard existed when avoiding artificial rotary top bar.
