Description

Automatic guide mechanism that leads of hot press die floating type [ Field of technology ] The invention relates to the technical field of die mechanisms, in particular to a guide mechanism for automatically guiding a hot press die in a floating mode. [ Background Art ] As shown in fig. 1-2, the mold core 20 and the mold plate 30 are balanced and positioned by adopting the floating positioning pins 40 in the mold plate 30, the floating positioning pins 40 have a certain floating range, because the mold core 20 is limited by space, the mold core can only be connected in the mold plate 30 through four groups of positioning pins 50, the holes of the positioning pins 50 can only be blind holes, and because of the height problem of the mold core, the depth of the positioning pins 50 penetrating into the mold core 20 is only 2/3 of the aperture of the blind holes, so that the positioning effect is poor, the mold core 20 installed behind the mold plate 30 is easy to shake, and the product meat thickness difference and the break difference are large. In view of the foregoing, it is desirable to provide a guiding mechanism for floating automatic guiding of a hot press die to solve the above-mentioned problems. [ Invention ] The invention aims to solve the technical problems that a mechanism for balancing the positioning of a die core by adopting a floating type positioning pin in a die plate has a certain floating range, the die core is limited by space and can only be connected in the die plate by four groups of positioning pins, the holes of the positioning pins can only be blind holes, and the depth of the positioning pins penetrating into the die core is only 2/3 of the aperture of the blind holes due to the height problem of the die core, so that the positioning effect is poor, the die core arranged on the die plate is easy to shake, and the difference of the meat thickness and the break difference of products are large.
