Description
Technical Field
The utility model belongs to the machinery manufacturing industry, and particularly relates to a mold locker.
Background
In the process of casting and producing the non-ferrous metal low-pressure metal mold, the accidents of mold expansion and fire escape are caused due to insufficient mold clamping force, so that a casting is cracked or deformed, and the conventional locking mode of a non-ferrous metal casting mold generally adopts a hydraulic locking mode. In the locking mode, the upper part of the locking mechanism is not provided with the pull rod, so that the bottom plate is easy to bend and is influenced by the bending force of the bottom plate, the locking of the metal casting mold is difficult to achieve, and the casting process requirement of the metal casting mold cannot be met.
Disclosure of Invention
The utility model aims to overcome the technical defects and provide the mould locker which has a simple structure, can realize strong locking between moulds and can avoid the accidents of mould expansion and fire escape.
The technical scheme adopted by the utility model for solving the technical problem is as follows: the mold locker comprises a first limit nut, a second limit nut and a rotating shaft, and is characterized in that the movable clamping jaw and the fixed clamping jaw are connected through a rotating shaft hinge and limited by a cotter pin, a movable clamping jaw inclined plane is arranged below the right end of the movable clamping jaw, a movable clamping jaw bayonet is arranged below the left end of the movable clamping jaw, a fixed clamping jaw bayonet is arranged below the fixed clamping jaw, an adjusting screw rod is movably inserted in a boss above the right end of the fixed clamping jaw and axially limited through the first limit nut and the second limit nut, a flat adjusting handle is arranged at the right end head of the adjusting screw rod, an adjusting wedge is connected with the left end head of the adjusting screw rod in a threaded manner, the lower end face of the adjusting wedge is arranged on the upper end face of the fixed clamping jaw, an inclined iron inclined plane is arranged at the upper end of the adjusting wedge, and the inclined plane of the inclined iron corresponds to the movable clamping jaw inclined plane.
The utility model has the beneficial effects that: the mold locker is simple in structure, the left mold and the right mold are strongly locked to reduce the deformation of castings and avoid the occurrence of other quality problems in the production process, the mold locker is convenient and flexible to use, the installation positions and the installation quantity can be set as required, the operation is time-saving and labor-saving, the service life of a low-pressure casting machine can be prolonged, and the production requirement of casting quality is completely met.

Detailed Description
In the embodiment, referring to fig. 1, a movable clamping jaw 2 and a fixed clamping jaw 5 of a mold locker are hinged through a rotating shaft 1 and limited by a cotter pin. A movable clamping jaw inclined plane 2-1 is arranged below the right end of the movable clamping jaw 2, a movable clamping jaw bayonet 2-2 is arranged below the left end of the movable clamping jaw 2, and a fixed clamping jaw bayonet 5-1 corresponding to the movable clamping jaw bayonet 2-2 is arranged below the fixed clamping jaw 5. An adjusting screw rod 4 is movably arranged in a boss above the right end of the fixed clamping jaw 5 in a penetrating mode, the adjusting screw rod 4 is axially limited through a first limiting nut 6 and a second limiting nut 7, a flat adjusting handle 4-1 is arranged at the right end of the adjusting screw rod 4, the left end of the adjusting screw rod 4 is in threaded connection with an adjusting wedge 3, the lower end face of the adjusting wedge 3 is arranged on the upper end face of the fixed clamping jaw 5, a wedge inclined face 3-1 is arranged at the upper end of the adjusting wedge 3, and the wedge inclined face 3-1 corresponds to the movable clamping jaw inclined face 2-1.
The use process of the mould locker is as follows: and (3) starting to close the die, closing the die, adjusting the adjusting wedge 3 to the right side by rotating the adjusting screw rod 4 through the flat adjusting handle 4-1 to enable the distance between the movable clamping jaw bayonet 2-2 and the fixed clamping jaw bayonet 5-1 to be the largest, then installing the die according to the process requirement, and rotating the adjusting screw rod 4 to enable the adjusting wedge 3 to move left to enable the distance between the movable clamping jaw bayonet 2-2 and the fixed clamping jaw bayonet 5-1 to be reduced to be locked. And (3) the casting starts to be filled and cooled, after the cooling time is up, the adjusting screw rod 4 is rotated to adjust the adjusting wedge 3 to the right side, so that the clamping jaw 2-2 and the fixed clamping jaw 5-1 are separated from the mold, then the casting is opened to a set position, the casting is taken out, and a production cycle is completed.
