Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a mould safety lock.

Referring to fig. 1 and 2, the lock comprises a lock body 1, wherein the lock body 1 is cylindrical, a rotating hole 2 is axially formed in the lock body 1 along the lock body 1, the axis of the rotating shaft 3 is perpendicular to one side, close to the lock body 1, of a mold, and the rotating hole 2 penetrates through the lock body 1. The coaxial axis of rotation 3 that wears to be equipped with in the rotation hole 2, and mounting hole 4 has been seted up to one side that the movable mould 001 is close to the

lock body

1, and 3 coaxial through rotation holes 2 and the coaxial mounting hole 4 that penetrates of axis of rotation, the coaxial bearing 7 that is fixed with in the mounting hole 4, the axis of rotation 3 penetrate the one end and the bearing 7 transition fit in the rotation hole 2. The movable mould 001 and the cover half 002 dock mutually and are close to the equal pre-buried spacing post 6 in edge of lock body 1, and lock body 1 has seted up two spacing holes 5 on being close to one side of mould, and two spacing holes 5 are around the axis symmetric distribution of lock body 1, spacing post 6 and spacing hole 5 one-to-one. When the lock body 1 fixes the movable die 001 and the fixed die 002, the limiting column 6 penetrates into the limiting hole 5 and is in inserting fit with the limiting hole 5. Offer on the lock body 1 and dodge groove 8, dodge groove 8 and run through lock body 1 along being on a parallel with the axial direction of lock body 1, dodge groove 8 and run through lock body 1 along 1 radial part of lock body, dodge groove 8 total two and with 6 one-to-one of spacing post, two dodge groove 8 around 1 axial symmetric distribution of lock body. When the lock body 1 loosens the fixed die 002 and the movable die 001, the limiting column 6 penetrates into the corresponding avoiding groove 8 and is matched with the avoiding groove 8 in a sliding mode.

When the movable mould 001 and the cover half 002 are fixed, the operator firstly pulls the lock body 1 along the axial direction of the rotating shaft 3, then rotates the lock body 1 to align the limiting column 6 with the limiting hole 5, and then presses down the lock body 1 along the axial direction of the rotating shaft 3 to enable the limiting column 6 to penetrate into the limiting hole 5. When loosening the cover die 002 and the movable die 001, the worker firstly lifts the lock body 1 along the axial direction of the rotating shaft 3 and then rotates the lock body 1 to align the limiting column 6 to the avoiding groove 8, then presses down the lock body 1 along the axial direction of the rotating shaft 3 to enable the limiting column 6 to penetrate into the avoiding groove 8, and then the cover die 002 and the movable die 002 can be separated.

Referring to fig. 1, in order to enable the limiting columns 6 to penetrate into the limiting holes 5 or the avoiding grooves 8 more smoothly, guide inclined surfaces 61 are formed at one ends of the two limiting columns 6, which are far away from the mold.

Referring to fig. 2, a snap ring 21 is coaxially formed in the rotation hole 2. One end of the rotating shaft, which is far away from the die, is formed with a chuck 31, the chuck 31 is cylindrical, and the chuck 31 is coaxially embedded in the rotating hole 2 and is in sliding fit with the rotating hole 2. An elastic part 9 is arranged between the clamping head 31 and the clamping ring 21, in the embodiment, the elastic part 9 is a spring 91, the spring 91 is coaxially sleeved on the rotating shaft, one end of the spring 91 abuts against one side of the clamping ring 21 close to the clamping head 31, the other end of the spring 91 abuts against one side of the clamping head 31 close to the clamping ring 21, and the spring 91 is in a contraction state.

After the limiting column 6 penetrates into the limiting hole 5, the spring 91 drives the lock body 1 to abut against the surface of the mold, so that the limiting column 6 is firmly fixed in the limiting hole 5.

Referring to fig. 2, in order to reduce the loosening of the lock body 1 during the fixing of the mold 002, an anti-slip gasket 12 is fixed on one side of the lock body 1 close to the mold in an adhesive manner, and one side of the anti-slip gasket 12 close to the mold abuts against one side of the mold close to the lock body 1.

Referring to fig. 1 and 2, the spring 91 enables a worker to overcome the elastic force of the spring 91 when pulling the lock body 1, so that the lock body 1 is formed with anti-slip threads 11 around the circumference of the axis of the lock body 1, so that the lock body 1 is not easy to slip when the worker pulls the lock body 1.

The implementation principle of the embodiment of the application is as follows: when the movable die 001 and the fixed die 002 are fixed, a worker firstly pulls the lock body 1 along the axial direction of the rotating shaft, then rotates the lock body 1 to enable the limiting column 6 to be aligned with the limiting hole 5, and then presses down the lock body 1 along the axial direction of the rotating shaft to enable the limiting column 6 to penetrate into the limiting hole 5. When loosening cover die 002 and movable mould 001, the staff earlier along axis of rotation axial lift pull lock body 1, rotatory lock body 1 again makes 6 alignment of spacing post dodge the groove, then pushes down lock body 1 along the axis of rotation axial, makes spacing post 6 penetrate and dodge in the groove, and then makes cover die 002 and movable mould 001 can separate.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
