The difference from this embodiment based on the above embodiment is that: as shown in fig. 4, fig. 5, fig. 6 and fig. 7, the side wall of the temporary storage box 401 is provided with a pressing assembly 600, the pressing assembly 600 comprises a pair of swing arms 6032, one side end of each of the pair of swing arms 6032 is movably hinged to the side wall of the temporary storage box 401, the other side end of each of the pair of swing arms 6032 is movably hinged to a guide block 603, the pair of swing arms 6032 are splayed, the guide blocks 603 are slidably arranged on the surface of a guide rail 6031 arranged in the lower die body 101, a movable rotating shaft 6011 is mounted on the guide block 603 through a bearing, a positioning gear 602 is mounted on the surface of the rotating shaft 6011, a positioning rack 6021 is movably meshed at the bottom of the positioning gear 602, and the bottom of the positioning rack 6021 is fixedly arranged in the lower die body 101. The pivot 6011 central point puts and is provided with the roller 601 that rolls, and roller 601 surface is provided with a plurality of archs that roll, and rolls roller 601 and be located connecting pipe 5011 top, and connecting pipe 5011 and straight tube 5021 junction is provided with receives press bag 502, receives press bag 502 material and is rubber material, and presses press bag 502 bottom height to be higher than roller 601 bottom height that rolls. In the process of moving up the jacking unit 400, the position of the swing arm 6032 is driven to change, the swing arm 6032 pulls the guide block 603 with the movable end connected to the tail end to move to the center, the rotating shaft 6011 at the center of the guide block 603 synchronously moves to the center, and then the positioning gear 602 at the center of the rotating shaft 6011 is driven to start to horizontally move along the positioning rack 6021, so that the positioning gear 602 and the rotating shaft 6011 are driven to synchronously rotate, the tail end of the rotating shaft 6011 is connected with the grinding roller 601, at the moment, the grinding roller 601 starts to move to the center, the grinding roller 601 starts to autorotate, after the grinding roller 601 is contacted with the pressure-receiving bag 502, the release agent in the pressure-receiving bag 502 starts to be extruded, and then the release agent is driven to spray from the spray head 4021 in the temporary storage box 401, and the release agent is sprayed on the lower die core 1011 in the interior. Namely, after the lower die body 101 and the upper die body 102 are mounted, the release agent is automatically applied.
The implementation principle of the rubber hot-press forming die of the embodiment is as follows: when the device is needed, the lower die body 101 and the upper die body 102 are correspondingly installed, the clamping rod 1023 at the bottom of the upper die body 102 is aligned with the installation unit 300 in the lower die body 101, in the process of downward movement of the clamping rod 1023, the clamping rod 1023 contacts with the guide wheel 3022, the guide wheel 3022 and the installed locking rod 302 are driven to rotate outwards around the positioning shaft 303 in the downward movement process because of the cylindrical shape of the clamping rod 1023, the clamping rod 1023 can be further enabled to move downwards all the time, and after the guide wheel 3022 moves to the position above the clamping rod 1023, the locking rod 302 is conveniently reset through the torsion spring 3031 due to the torsion spring 3031 being connected to the inside of the positioning shaft 303 and is clamped above the clamping rod 1023.
In the above operation, the locking bar 302 is first rotated outwards and rotated inwards when reset, and the length of the locking bar 302 is smaller than the length of the pry bar 304, i.e. the distance by which the end of the locking bar 302 rotates is greatly increased at the end of the pry bar 304, the balls 3041 at the end of the pry bar 304 slide on the bottom of the jacking unit 400, and finally the steel pipe 402 inside the jacking unit 400 is driven to move inside the lower mold core 1011, and the spray head 4021 is also exposed.
In the process of moving up the jacking unit 400, the position of the swing arm 6032 is driven to change, the swing arm 6032 pulls the guide block 603 with the movable end connected to the tail end to move to the center, the rotating shaft 6011 at the center of the guide block 603 synchronously moves to the center, and then the positioning gear 602 at the center of the rotating shaft 6011 is driven to start to horizontally move along the positioning rack 6021, so that the positioning gear 602 and the rotating shaft 6011 are driven to synchronously rotate, the tail end of the rotating shaft 6011 is connected with the grinding roller 601, at the moment, the grinding roller 601 starts to move to the center, the grinding roller 601 starts to autorotate, after the grinding roller 601 is contacted with the pressure-receiving bag 502, the release agent in the pressure-receiving bag 502 starts to be extruded, and then the release agent is driven to spray from the spray head 4021 in the temporary storage box 401, and the release agent is sprayed on the lower die core 1011 in the interior. Namely, after the lower die body 101 and the upper die body 102 are mounted, the release agent is automatically applied.
Then, rubber particles are added to the inside through the injection holes 1022, the resistance heating wire 1012 is started to heat the rubber particles inside, and after the rubber particles are melted, the lower mold core 1011 and the upper mold core 1021 are in the shape of a workpiece, and at this time, a demolding operation is required.
The stepping motor 201 is started, the rotating shaft 2021 connected with the tail end of the output shaft is driven by the stepping motor 201 to start rotating, the tail end cam 202 is driven to start rotating after the rotating shaft 2021 rotates, when the farthest end of the cam 202 is contacted with the pressing plate 203, the pressing plate 203 is pressed, the pressing plate 203 is positioned in the lower die body 101, the cam 202 is arranged in the upper die body 102, and the upper die body 102 and the lower die body 101 are driven to start separating through the pressing of the cam 202.
After the separation starts, the clamping rod 1023 starts to move upwards, drives the locking rod 302 inside the installation unit 300 to start rotating, drives the jacking unit 400 to move upwards through the rotation of the coaxially connected pry bar 304, and the jacking block 403 inside the jacking unit 400 can move upwards to jack the rubber workpiece inside the lower die core 1011, so that the later demoulding operation is facilitated.
