The utility model discloses a mould base clamping device mainly is applied to and has the scene of the risk that drops in mould base transfer process.

Referring to fig. 1, fig. 2 and fig. 3, a mold base clamping device, including installation piece 2 and mold bottom plate 6, fixedly connected with dead lever 1 on one side outer wall of installation piece 2, be equipped with the installation axle on one side inner wall of installation piece 2, be connected with sleeve 3 through the bearing on the outer wall of installation axle, fixedly connected with movable rod 17 on one side outer wall of sleeve 3, the bottom of movable rod 17 and dead lever 1 all is equipped with installation pole 5, gripper jaw 8 is all installed to the one end of two installation poles 5, all be equipped with supplementary fixture on two gripper jaws 8, gripper jaw 8 and the cooperation of supplementary fixture are used, be equipped with adaptation groove 7 on the circumference outer wall of mold bottom plate 6, the inner wall in adaptation groove 7 and gripper jaw 8's outer wall looks adaptation.

In concrete use, set up dead lever 1 and movable rod 17 respectively on the both sides position of installation piece 2, when holding the operation through the staff, can drive movable rod 17 and be close to dead lever 1 one side, along with being close to of dead lever 1 and movable rod 17, the gripper jaw 8 of both bottoms can carry out the centre gripping to the both sides of die bed board 6, and two gripper jaws 8 all imbed the inside in adaptation groove 7, begin the centre gripping.

Under the action of the gravity of the die bottom plate 6, partial gravity can be converted into acting force of two clamping claws 8 approaching to each other by combining stress analysis, and the acting force participates in clamping the die bottom plate 6 by the fixed rod 1 and the movable rod 17.

Referring to fig. 3, in a preferred embodiment, the auxiliary gripping mechanism comprises: mounting pads 18, an inserted bar 14, a reset spring 15, a slot 13, a connecting rod 16, a sliding rod 4 and an adaptation pad 19, the slot 13 is arranged on the inner wall of the mounting rod 5, the inserted bar 14 is inserted into the inner wall of the slot 13, the adaptation pad 19 is arranged at one end of the inserted bar 14 far away from the mounting rod 5, a fixing groove is formed in the outer wall of one side of the clamping jaw 8 and communicated with the slot 13, the reset spring 15 is adjusted on the outer wall of the inserted bar 14, the reset spring 15 is located between the adaptation pad 19 and the fixing groove, the two connecting rods 16 are respectively connected onto the outer walls of two sides of the inserted bar 14 close to the adaptation pad 19 through hinges, the two sliding rods 4 are respectively connected onto the inner walls of two sides of the clamping jaw 8, one ends of the two connecting rods 16 far away from the inserted bar 14 are respectively connected onto the opposite ends of the two sliding rods 4 through hinges, and the two mounting pads 18 are respectively connected onto one ends of the two sliding rods 4.

Specifically, when the two clamping jaws 8 clamp the die base plate 6, the die base plate 6 can reversely support the adapter pad 19 on the opposite side of the two clamping jaws 8, and when the adapter pad 19 is extruded, the inserted link 14 can contract towards the inside of the slot 13, and meanwhile, the connecting link 16 hinged on the two sides of the inserted link 14 can reversely support the movable link 17 inside the clamping jaw 8, so that the two movable links 17 are driven to extend outwards together with the mounting pad 18 at one end of the movable link 17.

Wherein, the outer wall of the opposite side of the two mounting pads 18 is arranged to be a cambered surface structure, which is beneficial to adapting to the outer surface of the die base plate 6.

The mounting pad 18 is made of rubber, so that friction between the mounting pad 18 and the die base plate 6 is increased, and therefore, in the clamping process, contact points between the integral clamping part and the die base plate 6 are more, and the clamping area is larger.

Referring to fig. 1 and 2, in a preferred embodiment, a grip 11 is disposed on an outer wall of the fixed rod 1 near the movable rod 17, and cushions 12 are disposed on inner walls of the grip 11 near the movable rod 17 and are distributed at equal intervals.

When the clamping device is used by a worker, the soft pad 12 on the inner wall of the handle 11 can play a role in buffering at the position contacted by the hand of the worker, so that the clamping device is more comfortable.

Referring to fig. 2, in a preferred embodiment, the outer wall of the opposite side of the movable rod 17 and the handle 11 is respectively provided with a limit strut 9 and an adaptive stop 10, one end of the limit strut 9 is provided with a collision bead, and the outer wall of one side of the adaptive stop 10 is provided with a groove, and the collision bead is matched with the groove.

Specifically, the bead and the groove provided between the grip 11 and the movable rod 17 are adapted, and when they are in contact, there is still a gap between the grip 11 and the movable rod 17.

When an error occurs in the clamping process, the two clamping claws 8 can fall off from the die bottom plate 6, and fingers cannot be pinched by the movable rod 17 and the handle 11 which are suddenly close to each other.

The working principle is as follows: when the clamping device is used, when the clamping device is held by a hand to operate, the clamping jaws 8 are aligned to the adaptation grooves 7 in the outer wall of the die base plate 6, then the movable rods 17 are driven to approach one side of the fixed rod 1, along with approach of the fixed rod 1 and the movable rods 17, the clamping jaws 8 at the bottoms of the fixed rod 1 and the movable rod 17 can clamp two sides of the die base plate 6, the two clamping jaws 8 are embedded into the adaptation grooves 7, partial gravity can be converted into acting force of the two clamping jaws 8 approaching to each other under the action of gravity of the die base plate 6, the acting force can participate in clamping of the die base plate 6, meanwhile, when the two clamping jaws 8 clamp the die base plate 6, the adaptation pads 19 can be extruded, the inserting rods 14 can contract towards the inside of the inserting grooves 13, meanwhile, the connecting rods 16 hinged to two sides of the inserting rods 14 can reversely support the movable rods 17 inside the clamping jaws 8, the two movable rods 17 and the mounting pads 18 at one ends of the movable rods 17 are driven to extend outwards, therefore, more contact points of the whole clamping portions and the die base plate 6 are calculated, operation points can be avoided due to be mistakenly clamped with the adaptation effect of the fingers.

The above is only the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto. The substitution may be of partial structures, devices, method steps, or may be a complete solution. According to the utility model discloses a technical scheme and utility model design and equal replacement or change all should be covered within the scope of protection of the utility model.
