The upper die of the apparatus is typically raised and lowered by a motor, hydraulic cylinder, or pneumatic cylinder. In a large molding apparatus, the upper mold generally has a large mass and is easily dropped. Particularly, when the upper die is driven by a hydraulic cylinder or an air cylinder, the upper die can fall under the condition that the hydraulic cylinder or the air cylinder loses pressure due to failure. On the other hand, this kind of former probably needs the manual work to go up unloading, and the shaping clearance, when the manual work was gone up the unloading, goes up the mould and falls and have life safety's risk.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 illustrates an upper and lower die forming apparatus. The upper and lower mold forming apparatus includes a frame 900, an upper mold 1, and a lower mold 4. Wherein the rack 900 comprises a bottom platform 902 arranged at the bottom and a top platform 901 arranged at the top of several columns. The top stage 901 is located above the bottom stage 902. The lower mold 4 is set on the base 902. The upper die 1 is set on the top stage 901 by the lifting mechanism 2, and is driven to lift by the lifting mechanism 2. Specifically, the lifting mechanism 2 includes a lifting drive mechanism 21, a lifting guide mechanism 22, and a lifting frame 23. The lifting driving mechanism 21 adopts an oil cylinder, and the lifting guide mechanism 22 adopts a plurality of guide post and guide sleeve mechanisms. The lift frame 23 is provided on the top stage 901 via a lift drive mechanism 21 and a lift guide mechanism 22. The upper die 1 is arranged on the lifting frame 23. When the equipment is formed, the upper die 1 is driven by the lifting mechanism 2 to be in butt joint with the lower die 4 for die assembly, after the forming, the upper die 1 is driven by the lifting mechanism 2 to be lifted to the highest position, and at the moment, loading and unloading can be carried out. The upper die 1 and the lifting mechanism 2 form an upper die mechanism. The upper die mechanism is the anti-falling upper die mechanism. In addition to the die 1 and the lifting mechanism 2, the upper die mechanism also includes a hooking mechanism 3. The two hook mechanisms 3 are symmetrically arranged on two sides and are oppositely arranged. When the lifting frame 23 is lifted to the highest position, the two hook mechanisms 3 are positioned at the two sides of the lifting frame 23, therefore, the lifting frame 23 can be hooked by the two hook mechanisms 3 at the two sides to avoid the lifting driving mechanism 21 from falling off when in failure.

Referring to fig. 2 and 3, the hooking mechanism 3 includes a cylinder 31, a hook 32, and a fastener 33. The air cylinder 31 and the hook 32 are provided on the top stage 901 through the mounting bracket 34, and are located below the top stage 901. Specifically, the hook 32 has an -shaped structure, one end of which is disposed on the mounting bracket 34 through the swing shaft 321, and is disposed on the rack 900 through the mounting bracket 34 disposed on the top stage 901. The other end of the hook 32 is provided with a hook groove 322 with a U-shaped structure. The hook 32 can swing around the axis of the swing shaft 321. The cylinder 31 is provided on the mounting bracket 34 through the first hinge 311, and is provided on the frame 900 through the mounting bracket 34 provided on the top stage 901. The air cylinder 31 is connected to the hook 32 by a second hinge 312 so that the hook 32 can swing about the swing shaft 321 by the driving of the air cylinder 31. The mounting bracket 34 is composed of a mounting plate 341, a side bracket plate 342, and an end bracket plate 343. The side frame plates 342 are two. The two side bracket plates 342 are arranged in parallel and fixed with the mounting plate 341. The end bracket plate 343 is fixed to the two side bracket plates 342 and forms a U-shaped structure with the two side bracket plates 342. The first hinge 311 is provided on the end bracket plate 343 through a hinge mounting bracket 344. The fastener 33 is provided on the lifting frame 23. The fastener 33 is a plate structure, and a fastening opening 331 is formed at the bottom. When the lifting frame 23 is lifted to the highest position, the hook 32 can be clamped into the buckle opening 331 under the driving of the air cylinder 31, and the lifting frame 23 can be hung on the rack 900 through the hook 32 by the matching of the buckle opening 331 and the hook groove 322.
