the top of the sliding block is provided with an oblique guide hole 12 which is arranged in parallel to the oblique guide post;
in the die opening state, the bottom of the inclined guide post is arranged right above the inclined guide hole; in the die closing process, the bottom of the inclined guide post is inserted into the inclined guide hole, and the slide block and the core-pulling block are pushed to move leftwards through the inclined guide post.
In the embodiment, the die assembly is firstly carried out, the movable die is contacted with the fixed die, in the process, the inclined guide post is firstly inserted into the inclined punching hole, the top of the inclined guide post is positioned at the left side of the bottom of the inclined guide post, in the process that the fixed die and the movable die are close to each other, the inclined guide post can work to move leftwards to drive the core-pulling block to be inserted into the movable die cavity, then the die-casting work is carried out, in the process, the product at the core-pulling block is a hole position, after the die-casting is finished, the fixed die is separated from the movable die, in the process, when the inclined guide post is separated from the inclined guide hole, the slide block is pushed to move rightwards, namely, the left side of the core-pulling block is driven to retract into the movable die cavity from the movable die cavity, so that the core-pulling block can be separated from the product, in order to ensure the separation stability, the inclined guide post is smoothly separated from the inclined guide hole, the restoring mechanism can also give right restoring force to the slide block, so that when the inclined guide post is separated from the inclined guide hole, the oblique guide pillar can be smoothly separated from the oblique guide hole. That is, after the die is opened, the core-pulling block can be separated from the product, so that the blanking block of the product has high efficiency, good quality and good stability.
Referring to fig. 1 and 2, the restoring mechanism includes an installation block 13, a guide cylinder 14, a connecting rod 15 and a spring 16, the installation block is installed on the right side surface of the movable mold, the installation block is provided with a guide hole 17, the guide hole is arranged opposite to the notch, the guide cylinder is installed on the right side surface of the installation block, the left side of the guide cylinder is provided with a cavity 18, the cavity is communicated with the guide hole, the left side of the connecting rod is connected with the right side of the sliding block, and the right side of the connecting rod penetrates through the guide hole and is inserted into the cavity of the guide cylinder;
the right-hand member spiro union of connecting rod has a nut 19, the nut set up in the cavity, the spring housing is located on the connecting rod, the left side of spring support in on the right flank of installation piece, the right side of spring support in on the left surface of nut, the spring promotes connecting rod, slider and the piece of loosing core move towards the right side.
In this embodiment, under the condition of die sinking, the spring can promote connecting rod, slider and the piece of loosing core and move towards the right side for the slant guide hole of slider is just to the bottom of oblique guide pillar, and in the compound die, the bottom of oblique guide pillar can the disect insertion to the slant guide hole in, guarantees the stability of compound die, can not appear colliding and will die-casting die damage.
In this embodiment, still can set up a bar and lead to groove 20 on the guide cylinder, the bar leads to groove and cavity intercommunication, and whether operating personnel can real-time observation inside spring can normal use like this, and the timely discovery problem of being convenient for is maintained.
The guide cylinder is characterized in that an installation plate is arranged on the outer edge face of the left side of the guide cylinder, and the installation plate is connected with the right side of the installation block through a plurality of groups of bolts.
An extension block 22 extending towards the left is arranged above the left side of the mounting block, the extension block is inserted into the gap, the left side of the guide hole is communicated with the left side face of the extension block, and the right side of the sliding block is close to the extension block in the extending state of the spring.
Referring to fig. 1 and 2, a first guide inclined plane 23 is arranged on the right side surface of the slider, and the first guide inclined plane is inclined from top to bottom to the right; the right side of the bottom surface of the fixed die is provided with a positioning block 24 extending downwards, the positioning block is arranged right opposite to the notch, the left side surface of the positioning block is a second guide inclined surface 21, the second guide inclined surface is parallel to the first guide inclined surface, the positioning block is arranged on the right side of the inclined guide pillar, and the bottom surface of the positioning block is arranged above the bottom surface of the inclined guide pillar.
In a die assembly state, the inclined guide post is inserted into the inclined guide hole, and the second guide inclined plane is abutted against the first guide inclined plane.
In this embodiment, when die-casting, pressure is great among the die-casting process, can give the great right thrust of the piece of loosing core like this, and slider and oblique guide pillar can bear great pressure like this, long-time the use, and oblique guide pillar is out of shape the damage easily. And during die assembly, the inclined guide post is inserted into the inclined guide hole, the slide block is pulled to move towards the left, and the spring is required to be compressed. Therefore, through the arrangement of the positioning block and the arrangement of the first guide inclined plane and the second guide inclined plane, when the die is closed, when the positioning block is not in contact with the sliding block, the inclined guide post is used for pulling the sliding block to move towards the left, when the first inclined plane of the sliding block moves to the position below the second inclined plane of the positioning block, the second inclined plane is in contact with the first inclined plane, the positioning block is continuously close to the sliding block, thus, the second inclined plane can extrude the first inclined plane to push the slide block to move towards the left, the spring is compressed, the pressure of the inclined guide post is reduced, the deformation of the inclined guide post is prevented, and, in the process of die-casting, the fixed die and the movable die are locked together by using a die locking force, the sliding block is clamped by using the positioning block, and the thrust given to the core-pulling block by die-casting can be propped by the positioning block, so that the inclined guide pillar is prevented from being deformed due to overlarge stress, the smooth die-casting is ensured, the service life is prolonged, the maintenance rate is reduced, and the cost is reduced.
