Technical Field

The invention relates to a centrifugal casting machine, in particular to a mold locking and opening structure of the centrifugal casting machine.

Background

MC nylon is also called as casting nylon, because of its good physical and chemical properties, its status in engineering plastics rises rapidly and applies to various industries gradually, its production process is similar to the metal centrifugal casting process, usually adopt the centrifugal casting machine to produce, preheat the upper die and lower die in the centrifugal casting machine and make the upper die and lower die close the mold, then inject the raw materials into the preheated upper die and lower die of the nylon centrifugal casting machine directly, and then drive the upper die and lower die to rotate by the motor, make the raw materials carry on polymerization reaction rapidly and solidify the shaping in the mould, then open the mold and take out the casting, but the mold closing process of the existing centrifugal casting machine is usually the manual mold closing and opening, for example fasten the upper die and lower die by way of threaded connection, the corresponding mold opening process also needs the manual work to loosen the bolt connecting the upper die and lower die and then open the mold, the mode of closing and opening the die greatly reduces the production efficiency and increases the potential safety hazard.

Disclosure of Invention

The invention aims to provide a mold locking and opening structure of a centrifugal casting machine, which greatly improves the production efficiency and reduces the potential safety hazard in a mechanical mold locking mode.

In order to realize the aim, the invention provides a mold locking and opening structure of a centrifugal casting machine, which adopts the following technical scheme:

a mold locking and opening structure of a centrifugal casting machine comprises a driving mechanism, a first plate, a first mandrel, an upper mold, a second mandrel, a lower mold, a clamping plate, a clamping hook, an elastic piece and a linkage mechanism, wherein the driving mechanism is installed on a machine body of the centrifugal casting machine, the driving mechanism is provided with a movable end moving along a straight line, the movable end is connected with the first plate, the first mandrel is movably connected with the first plate, the lower end of the mandrel is connected with the upper mold, the middle part of the first mandrel is movably connected with the clamping plate, the elastic piece is arranged between the clamping plate and the upper mold, the clamping plate is provided with a clamping part, the lower mold is arranged at intervals below the upper mold, the lower mold is installed on the second mandrel, the second mandrel is rotatably connected with the machine body, the lower mold is rotatably connected with the clamping hook corresponding to the clamping plate, and the clamping hook, the linkage mechanism is arranged between the clamping hook and the upper die, and when the upper die moves towards the lower die, the linkage mechanism is used for enabling the clamping hook to move into the clamping part.

When the mould locking mechanism works and the mould is locked, the movable end driving plate of the driving mechanism moves downwards, the upper mould and the clamping plate move towards the clamping hook, the clamping hook moves into the clamping part under the action of the linkage mechanism, the driving mechanism stops descending and ascending, and the elastic body rebounds to push the clamping plate to move upwards, so that the clamping hook and the clamping plate are connected in a clamping manner.

Compared with the prior art, the invention has the beneficial effects that: realize automatic buckle through cardboard, trip under the link gear effect and connect to go up mould and lower mould mode locking, compare in artifical mode locking, very big improvement production efficiency, and solved the problem that there is the potential safety hazard in artifical mode locking.

On the basis of the technical scheme, the invention can be further improved as follows:

further: the clamping portion is a clamping hole formed in the clamping plate, the clamping hook is provided with a clamping groove, and the clamping groove is used for being connected with the clamping hole in a buckling mode.

Further: the linkage mechanism comprises a rack and a gear which are meshed in a matched mode, the rack is arranged on the upper die, the gear is rotatably connected to the lower die, and the clamping hook is arranged on the gear. The beneficial effect of this step: the rack is meshed with the gear, so that the linear motion of the rack is converted into the rotation of the clamping hook.

Further: the clamping plate is arranged on the second plate, and the elastic piece is arranged between the second plate and the upper die. The beneficial effect of this step: the second plate realizes the indirect connection of the elastic piece and the clamping plate.

Further: the die further comprises at least one positioning block, and the positioning blocks are arranged between the second plate and the upper die. The beneficial effect of this step: the maximum compression amount of the pressure spring is limited through the positioning block.

Further: the device further comprises a thrust bearing and a third plate, wherein the third plate is arranged between the second plate and the first plate and movably connected with the first mandrel, and the thrust bearing is arranged between the second plate and the third plate. The beneficial effect of this step: the second plate and the third plate can independently rotate through the thrust bearing without mutual influence.

Further: the height adjusting block is arranged on the upper end face of the plate III. The beneficial effect of this step: the height adjusting block is used for compensating the change of the mold locking position caused by the difference of the upper mold and the lower mold.

Further: the elastic piece is a pressure spring. The beneficial effect of this step: the pressure spring is easy to obtain, the manufacturing cost is low, and the working requirement can be met.

Further: the driving mechanism is an oil cylinder. The beneficial effect of this step: the oil cylinder is easy to obtain, the manufacturing cost is low, and the working requirement can be met.
