Abstract
The invention relates to a demoulding device, in particular to a press demoulding device. The invention aims to solve the problem that a greater potential safety hazard exists due to the fact that two push rods need to be supported with hand by people when press demoulding is performed in the prior art. The press demoulding device comprises a pressure head and a working table, wherein the pressure head is located at the upper part of a press; the working table is located at the lower part of the press and used for supporting a workpiece and mould assembly. The press demoulding device also comprises at least two push rods used for demoulding; each push rod is arranged at the upper end of a mould through a magnetic stand arranged at the lower part of the push rod. According to the press demoulding device provided by the invention, the lower end of each push rod is provided with the magnetic stand; the fixation and the disassembly of the push rods can be very easily realized by rotating switches of the magnetic stands; each push rod is fixedly arranged at the upper end of the corresponding mould by adopting a magnetic force, and therefore, the huge potential safety hazard existing when the push rods are manually supported with hand is avoided.
Description
Technical field
The present invention relates to a kind of stripper apparatus, relate in particular to a kind of press stripper apparatus.
Background technology
During the current demoulding, adopt be two square bars as the push rod of transmission of pressure, one end of push rod is placed on mould top, press is pressed in the other end of push rod, thereby realizes the demoulding; During work, must be by one man operation press, another people is holding up two push rod demouldings, has great potential safety hazard, and needs two people's operations, waste of manpower; In addition, push rod cannot stretch, thereby need to make the push rod of differing heights, causes the serious wasting of resources.
Summary of the invention
The invention provides a kind of press stripper apparatus, while being intended to solve in prior art the press demoulding, need people holding up two push rods, have the problem of larger potential safety hazard.
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 for the workbench of supporting workpiece and set of molds zoarium, also comprise that at least two for the push rod of the demoulding, described each push rod is all arranged on the upper end of mould by being arranged on the magnetic stand of its underpart.
Further, described mould comprises urceolus, be arranged on inner core on workbench, the cope match-plate pattern of upper end between urceolus and inner core, between urceolus and inner core lower end and be arranged on the lower bolster on workbench, 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 can not be pressed onto cope match-plate pattern, is convenient to push rod urceolus is pressed, and realizes the demoulding.
Further, described workbench comprises the base plate that is connected in press bottom, is connected in the annulus of plate upper surface, and described inner core is inserted in the centre bore of annulus and is fixed on base plate, 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; Workbench is fixed inner core and lower bolster, and the external diameter of annulus is less than the external diameter of lower bolster, makes urceolus can not encounter workbench, is conducive to urceolus to press smoothly.
Further, the lateral wall of described push rod extends the block suitable with urceolus lateral wall vertically downwards; Block is convenient to the location of push rod, prevents that push rod is pressed on cope match-plate pattern.
Further, described push rod has three and be evenly distributed on the circumference of mould; Very little, bearing pressure can be larger for push rod quantity, has the hidden danger fractureing; Push rod quantity is too many, can cause each push rod discontinuity, thereby 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 that need to adjust push rod, save resource and cost.
Further, the upper end that is positioned at push rod screwed hole on described each push rod is equipped with unthreaded hole, in described unthreaded hole, be provided with straight screw sleeve, the screwed hole that the threaded portion of the common composition of the screwed hole of centre of described straight screw sleeve and push rod screwed hole and extension bar matches, described straight screw sleeve is connected on push rod by trip bolt; By the fastening straight screw sleeve of trip bolt, can effectively prevent that 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, by the switch of rotation magnetic force gauge stand, be easy to realize the fixing and dismounting of push rod, adopt magnetic force push rod to be fixed on to mould upper end, the huge potential safety hazard existing while having avoided artificial rotary top bar.
