Description
Technical Field
The utility model relates to a high-pressure die-casting technical field, especially a demoulding structure is loosed core in high-pressure die-casting.
Background
Under the general condition, when the slider of high pressure die-casting aluminum alloy mould is loosed core and is wrapped tight power great, need form a complete set and use the great hydro-cylinder of loosing core of volume just to have sufficient pulling force to make the slider demolding, but such cost is higher, when using great hydro-cylinder of loosing core moreover, easy and die-casting machine production is interfered, makes this type of die-casting mould be difficult to install on the die-casting machine.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a demoulding structure is loosed core in high-pressure die-casting.
The utility model provides a technical scheme that its technical problem adopted is:
the high-pressure die-casting core-pulling demoulding structure comprises a fixed mould at the upper side and a movable mould at the lower side;
a sliding block cavity is formed in the side edge of the fixed die, a sliding block capable of translating is arranged in the sliding block cavity, and a sliding block core pulling is arranged on the sliding block;
a clamping groove is formed between the movable die and the sliding block, and the sliding block can move horizontally along the clamping groove;
the fixed die is characterized in that a first die guide block is arranged on the fixed die, a second die guide block is arranged on the sliding block, the first die guide block and the second die guide block can be in mutual contact, and an inclined plane inclined towards the upper side of the middle of the fixed die is arranged between the first die guide block and the second die guide block.
As an embodiment of the utility model, the slider upside is provided with sunken position, the second goes out the mould guide block and is located sunken position is inboard.
A high-pressure die-casting die comprises the high-pressure die-casting core-pulling demoulding structure.
The utility model has the advantages that: when the movable mold is ejected, the slider core is moved for a certain distance through the inclined surface contact between the first ejection guide block and the second ejection guide block, so that the tightening force of the slider core is greatly reduced.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1, the high pressure die casting core-pulling demoulding structure comprises a fixed mould 10 at the upper side and a movable mould 20 at the lower side. A sliding block cavity 11 is formed in the side edge of the fixed die 10, a sliding block 30 capable of translating is arranged in the sliding block cavity 11, and a sliding block core 40 is arranged on the sliding block 30. The slide block 30 is connected with the core-pulling oil cylinder and is driven to move by the core-pulling oil cylinder.
A clamping groove 50 is arranged between the movable mold 20 and the sliding block 30, and the sliding block 30 can translate along the clamping groove 50. That is, the movable mold 20 can clamp the slide block 30 through the clamping groove 50, so that the slide block 30 is also driven to move when the movable mold 20 moves, and meanwhile, the slide block 30 can also move in a translational manner relative to the movable mold 20 along the direction of the clamping groove 50. The cross-section of a particular card slot 50 may be T-shaped, L-shaped, or other similar shape.
The fixed die 10 is provided with a first die guide block 60, the slider 30 is provided with a second die guide block 70, the first die guide block 60 and the second die guide block 70 can be contacted with each other, and an inclined plane 80 inclined towards the upper side of the middle of the fixed die 10 is arranged between the first die guide block 60 and the second die guide block 70.
When the movable mold 20 is ejected, the movable mold 20 moves; then the second mold stripping guide block 70 also moves for a distance, the slide block core-pulling 40 simultaneously moves for a distance, and the wrapping force of the slide block core-pulling 40 is greatly reduced; and then the sliding block 40 is pulled out through the core pulling oil cylinder to complete the drawing out of the die casting product. When the mold is closed, the movable mold 20 and the fixed mold 10 are closed, then the core-pulling oil cylinder pushes the slide block core-pulling 40 back into the mold, and finally the mold closing state is formed.
The upper side of the slide block 30 is provided with a concave position 31, and the second mold stripping guide block 70 is positioned at the inner side of the concave position 31, so that the whole structure is more compact.
The utility model provides a high-pressure die-casting mould, includes above-mentioned high-pressure die-casting demoulding structure of loosing core, including the cover half 10 of upside, the movable mould 20 of downside, cover half 10 side is provided with slider chamber 11, but be provided with the slider 30 of translation in the slider chamber 11, it looses core 40 to be provided with the slider on the slider 30.
According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
