As shown in fig. 1 and 6: the jacking structure 6 works in the following manner: when the mold is opened, due to the clearance between the driven block 64 and the driving block 66, the driven block 64 and the driving block 66 cannot be contacted immediately at the moment of mold opening, when the driven block 64 is contacted with the driving block 66, the bottom surface of the driven block 64 is stressed to move from right to left at the moment, so that the connecting rod 61 drives the lifting plate 54 to move upwards and drives the mold core 51 to move upwards, the bottom surface of the profile product 4 is separated from the upper surface of the lower mold 53, and the cylinder formed by the runner 14 on the profile product 4 is held by hands, so that the demolding work is completed.
Detailed description nine: in this embodiment, as a further limitation of the eighth embodiment, the two ends of the passive block 64 are both provided with a limiting block 65, and the limiting block 65 is inserted with a limiting rod 63, the limiting rod 63 is fixedly disposed at the lower side of the inner portion of the mounting cavity 56, and the limiting rod 63 is provided with a return spring 62.
As shown in fig. 1: when the passive block 64 moves from right to left, the limiting rods 63 are inserted into the limiting blocks 65 on two sides of the passive block 64, and the limiting rods 63 can limit and guide the passive block 64 which moves transversely, so that the passive block 64 is prevented from tilting when moving.
Detailed description ten: this embodiment is further limited by the ninth embodiment, the passive block 64 is adapted to the size of the driving block 66, and the driving block 66 is disposed by contacting the pressing inclined surface on the driving block 66 with the pressing inclined surface on the driving block to the bottom of the passive block 64, and the pressing inclined surface is disposed parallel to the pressing inclined surface.
As shown in fig. 1 and 7: when the passive block 64 moves downwards, the bottom of the passive block is stressed by the stressed inclined surface facing the downward pressing inclined surface on the driving block 66, and drives the limiting block 65 to compress the return spring 62, and after the force acting on the passive block 64 disappears, the return spring 62 at the moment resets and rebounds to drive the passive block 64 to return to the initial position.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
