Specifically, the second limiting block 150 and the third limiting block 160 are both fixedly connected with the pulling plate 40 through bolts, the second limiting block 150 has a first contact inclined surface, the first contact inclined surface is located on the side portion of the second limiting block 150 in the mold closing direction of the first half mold and the second half mold, correspondingly, the first half mold 21 has a second contact inclined surface, and the second contact inclined surface is in contact with the first contact inclined surface in an attaching manner, so that the second limiting block 150 is in more stable contact with the first half mold 21, and the mold closing efficiency of the first half mold 21 and the second half mold 22 is further improved; similarly, the third limiting block 160 has a third contact inclined surface, the third contact inclined surface is located on the side of the third limiting block 160 along the mold closing direction of the first mold half 21 and the second mold half 22, the second mold half 22 has a fourth contact inclined surface, and the fourth contact inclined surface is in contact with the third contact inclined surface.
For a more clear explanation of the present invention, the following description will be made by taking the embodiment shown in fig. 1 to 5 as an example, and referring to fig. 6 to 10, with regard to the operation of opening the mold in sequence according to the present invention:
the first state: as shown in fig. 6, when the mold is opened from the clamped state (shown in fig. 1), the first mold plate 10 is in a stationary state with a deflector (the structure of which is known to those skilled in the art) fixed to the upper platen of the apparatus, and the lower plate 90 is moved downward in conjunction with the lower platen of the apparatus. Because the first connecting element 50 and the first fixing element 30 are connected between the lower plate 90 and the second template 20, and the second connecting element and the second fixing element are connected, when the first template 10 is attached to the pulling plate 40 or in a certain gap, the first connecting element 50 and the second connecting element are in an open state due to the limit of the first stopper 60, the first fixing element 30 and the second fixing element are hooked tightly, and the pulling plate 40 and the second template 20 are in a synchronous state within a certain stroke, therefore, at the initial stage of die sinking, the lower plate 90 drives the second template 20 and the pulling plate 40 to descend together, and the product is left in the second template 20.
State two and state three: as shown in fig. 7 and 8, when the mold is opened to a certain position, the first connecting member 50 is separated from the first fixing member 30, and the second connecting member is separated from the second fixing member, so that the first connecting member 50 and the second connecting member become free and droop under the action of gravity, and the distance between the bosses at the two sides is smaller than the distance between the first fixing member 30 and the second fixing member along the horizontal direction. When the position of the pulling plate 40 reaches the maximum stroke of the guide rod 71, the first limiting block 72 drags the pulling plate 40, and the lower plate 90 continues to drive the second template 20 to move downwards, so that the rubber product is separated from the pulling plate 40.
And a fourth state: as shown in fig. 9, after the lower hot plate is lowered to the lowest position and slides out, the first mold half 21 and the second mold half 22 are pulled apart in the horizontal direction by the pulling claws of the apparatus, the second stopper 150 and the third stopper 160 fixed to both sides of the second mold plate 20 are separated from the second mold plate 20, at this time, the distance between the second stopper 80 and the third stopper 120 in the horizontal direction is greater than the maximum length (i.e., the length of the head) of the third connecting member 100 in the horizontal direction, and the rubber product is separated from the second mold plate 20.
And a fifth state: as shown in fig. 10, the third mold plate 110 is separated from the lower plate 90 together with the second mold plate 20 by means of a side ejector of the apparatus, and the product is separated from the lower core (which is a structure of fig. 10, which is inserted in the middle of the lower plate 90), and is easily taken out only by a plane contact with the lower plate 90.
In conclusion, on one hand, the rubber product is ensured to be finally left on the lower template plane of the die, and the production abnormity caused by the fact that the rubber product is left at different positions is reduced; on the other hand, on the premise of not influencing the normal demolding action, the actions of all layers of templates are ensured to sequentially act in an automatic state of the equipment, so that the automation degree of the mold is improved, and the demolding efficiency of rubber products is obviously improved.
