Automatic end cover locking mechanism for centrifugal mould

Abstract

The invention discloses an automatic end cover locking mechanism for a centrifugal mould. The structure of the automatic end cover locking mechanism comprises a mould locking frame ring block, a parting locking panel, a column pin rod, an upper mould cavity plate, a beam sleeve, a mould releasing base and a lining plate. The mould locking frame ring block is matched with the parting locking panel;the mould locking frame ring block is inserted into a thick annular groove and a reinforcing rib panel is matched at a magnet propeller seat to form the overlying mobility of a magnet column block and a folding frame rib rod seat and the slot position locking operation of a bow-shaped propeller rod, so that a top cover of the mould forms a magnetic swirl lock effect, a rigid side is prevented from overlying column pins, and the interference rejection of the column pin rod is improved; a middle coverage locking effect is obtained at the axis end of a parting surface, the seam phenomenon of theparting surface in mould processing is improved, and the processing efficiency of seam tightening is improved; and moreover, the dressing link is saved through formed materials, the qualified quantity and engineering speed of assembly line batch processing are improved, and thus the swivel dexterity and sealed degree of the mould locking mechanism are improved.

Description

technical field [0001] The invention relates to an automatic end cover locking mechanism of a centrifugal mold, which belongs to the field of molds. Background technique [0002] The inner rotor of the centrifugal mold and the thimble of the cylinder have the effect of slow-release linkage and dislocation pressure, so that the upper and lower parting surfaces of the mold can be pressed with accurate mold precision, and then when the end cover of the later demoulding is lifted, the finished product of the small-pitch mold can be effectively released Surface layer, so as to facilitate the operation of mold taking and demoulding, and improve the ingenuity of mold processing. The shortcomings of the current technology that need to be optimized are: [0003] The end cover lock sleeve of the centrifugal spinning die is usually operated by covering and interspersing the pin, and when the side end cap frame of the pin is protected, it is easy to cause the rear side panel to be squee...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an automatic end cap locking mechanism for a centrifugal mold to solve the problem that the end cap lock sleeve of a centrifugal spinning die is usually operated with a cover type interspersed pin, and the side end of the pin When the hat frame is protected, it is easy to cause the rear side panel to be squeezed and recoiled to lift, thereby distorting the pin rod, resulting in a deviation in the fit of the secondary cover plate, and the mold processing operation with a gap will cause the molded material to stick to the side strip Excessive leftovers lead to a large amount of mold collection load in the later stage, and the flatness of the end face of the molding size is inclined, and the hinge force for the operation of tightening and inserting the end cover is insufficient, resulting in the continuous loss of the lock pin rod and causing fracture.
