As a preferable scheme of the invention, in order to ensure that the clapboard is kept not to incline when being pushed or pulled, the telescopic device adopts two groups of designs and is arranged on the cross beam side by side. The telescopic device reaches the bottom of the partition plate, and applies pushing force or pulling force to the position horizontal to the acting point when the telescopic device moves, so that the partition plate can move forwards or backwards in a vertical state, and the phenomenon of inclination is avoided.

Specifically, the locking module mainly comprises a locking block, a locking shaft, an unlocking rod, an unlocking rotating shaft, a first unlocking shaft and a second unlocking shaft. The locking block is designed to be of a triangular structure, and the first end of the locking block is fixed to the bottom plate of the mold car through a locking shaft and can rotate around the locking shaft. The unlocking rod is designed in an L-like structure and is positioned on one side of the locking block, and the turning part of the unlocking rod is fixed on the bottom plate of the mold car through an unlocking rotating shaft and can rotate around the unlocking rotating shaft. The unlocking rod is divided into an operation section and an unlocking section by taking the rotating center as a boundary point, and the unlocking section is a section close to the last partition plate.

One end of the guide block is fixed with the output end of the locking oil cylinder, and the other end of the guide block extends to the position above the guide station of the locking block. The unlocking oil cylinder is arranged on the wire production frame and positioned above the operation section of the unlocking rod, and the output end of the unlocking oil cylinder is fixedly connected with the unlocking block. When locking is needed, the locking oil cylinder drives the pilot block to move downwards until the pilot block is contacted with the arc-shaped notch of the locking block in an unlocking state, the locking block and the unlocking rod are driven to turn downwards, the unlocking oil cylinder continues to drive the pressing block to move downwards at the moment, downward pressure is applied to the third end of the locking block through the pressing block, and therefore the pressing block presses the last partition plate and locking operation of mold closing is completed.

As a preferable scheme of the invention, the side surface of the guide block adopts a triangular/wedge-shaped structural design. The design can make the guide block and the locking block poke by utilizing the inclined plane after the arc notch of the locking block is contacted, so that the center of the locking block can automatically overturn downwards under the action of gravity after crossing the rotating center.

As a preferable scheme of the invention, in order to avoid the situation that the locking block and the partition plate are in hard connection for a long time and are easy to damage or wear, the back of the last partition plate of the mould vehicle is also provided with an elastic backing plate. The backing plate adopts the arc structure, and the backing plate embedding baffle back, its edge height and baffle back parallel and level. The design just can guarantee that the latch segment keeps elastic connection between when locking and the baffle like this, after backing plate wearing and tearing or losing elasticity, can change in order to keep good elasticity performance, ensures the locking pressure of latch segment to the baffle.
