Background
The mold locking system has the functions of ensuring that the molding mold can be opened and closed flexibly, accurately, quickly, reliably and safely, and ensuring that the mold cavity of the mold is closed tightly and plastic melt cannot overflow out of the mold cavity. When the mold is closed in the prior art, the driving force of the mold locking system comes from mechanical power, but the stress points of the driving force on the movable mold plate are arranged on two sides of the movable mold plate, so that the stress of the mold is uneven, the mold is easy to deform, and the mold closing effect is poor.
SUMMERY OF THE UTILITY MODEL
To the current situation of above-mentioned prior art, the utility model provides a direct compression formula mode locking structure has the advantage that the atress is even, the compound die is effectual.
The utility model provides a technical scheme that above-mentioned technical problem adopted does:
the utility model provides a direct compression formula mode locking structure, includes back template, movable mould board, the back template with be connected with the shifting die hydro-cylinder between the movable mould board, the back template dorsad be provided with the mode locking hydro-cylinder on the lateral wall of shifting die hydro-cylinder, be provided with the oil inlet on the mode locking hydro-cylinder, the movable mould board with be connected with the pull rod between the back template, the movable mould board is in slide on the pull rod, the shifting die hydro-cylinder is close to the one end of movable mould board is located the center of movable mould board.
Through adopting above-mentioned technical scheme, oil gets into the mode locking hydro-cylinder from the oil inlet, and then promotes the moving die hydro-cylinder and remove toward the moving die plate direction, because the moving die hydro-cylinder is the center that promotes the template for the mould atress is even, and the difficult condition that takes place the plastics solution and spill over, and then makes the compound die effectual.
And a support column is connected between the movable template and the mold moving oil cylinder, one end of the support column is fixed on the movable template, and the other end of the support column is abutted against the mold moving oil cylinder.
By adopting the technical scheme, the supporting column provides a stress point for the mold moving oil cylinder, and the mold moving oil cylinder pushes the supporting column to push the movable template.
The mould moving oil cylinder comprises a pressure cylinder connected with the rear template and a piston rod sliding in the pressure cylinder, and one end of the piston rod, which is far away from the pressure cylinder, abuts against the supporting column.
By adopting the technical scheme, when oil slowly enters the pressure cylinder, the piston is pushed to move towards the direction of the supporting column due to the increase of hydraulic pressure, and then the movable die plate is pushed to finish die assembly.
Further, a reinforcing rib is arranged at the joint of the mould moving oil cylinder and the rear template.
Through adopting above-mentioned technical scheme, the strengthening rib can increase the joint strength between shifting formwork hydro-cylinder and the back template.
Compared with the prior art, the utility model has the advantages of:
the utility model provides a direct compression formula mode locking structure, including back template, movable mould board, the back template with be connected with the shifting die hydro-cylinder between the movable mould board, the back template dorsad be provided with the mode locking hydro-cylinder on the lateral wall of shifting die hydro-cylinder, be provided with the oil inlet on the mode locking hydro-cylinder, the movable mould board with be connected with the pull rod between the back template, the movable mould board is in slide on the pull rod, the shifting die hydro-cylinder is close to the one end of movable mould board is located the center of movable mould board. Because the mould moving oil cylinder pushes the center of the template, the stress of the mould is uniform, the plastic solution is not easy to overflow, and the mould closing effect is good.
Drawings
Fig. 1 is a schematic view of the overall structure of the direct-pressure mode-locking structure of the present invention.
In the figure: 1. a rear template; 2. moving the template; 3. a mould moving oil cylinder; 31. a booster cylinder; 32. a piston rod; 4. a mold locking oil cylinder; 41. an oil inlet; 5. a support pillar; 6. a pull rod; 7. and (5) reinforcing ribs.
Detailed Description
As shown in fig. 1, the utility model discloses a back template 1, movable mould board 2 are connected with between back template 1 and the movable mould board 2 and move the mould hydro-cylinder 3, are provided with mode locking hydro-cylinder 4 on the lateral wall that back template 1 moved mould hydro-cylinder 3 dorsad, are provided with oil inlet 41 on the mode locking hydro-cylinder 4. The side wall of the rear template 1 facing the mold moving oil cylinder 3 is fixedly connected with a support column 5, the support column 5 is positioned at the center of the movable template 2, and one end of the support column 5 abuts against the mold moving oil cylinder 3.
Four pull rods 6 are connected between the movable template 2 and the rear template 1, the movable template 2 and the rear template 1 are both square, the four pull rods 6 are respectively connected at four vertex angles of the movable template 2 and the rear template 1 in a penetrating manner, and the movable template 2 can slide on the pull rods 6. The mould moving oil cylinder 3 is positioned in the middle of the four pull rods 6, the mould moving oil cylinder 3 comprises a pressure cylinder 31 connected with the rear template 1 and a piston rod 32 connected with one end of the pressure cylinder 31 far away from the rear template 1, one end of the piston rod 32 slides in the pressure cylinder 31, and one end of the piston rod abuts against the support column 5; the joint of the pressure cylinder 31 and the rear template 1 is fixedly connected with a plurality of reinforcing ribs 7, and the reinforcing ribs 7 can increase the connection strength between the mold moving oil cylinder 3 and the rear template 1.
