2, be fixed by follower bolt.Shortcoming: need to prepare the cushion block of various height, mould replacing time is long; When using a plurality of cushion block, also there is potential safety hazard.
The utility model content
The utility model is high for the required precision that exists in the above-mentioned existing mold installation way, interchangeability is poor, mould replacing time is long and have the shortcoming such as potential safety hazard when using individual cushion block, and a kind of mould quick clamping mechanism is provided.
The mould quick clamping mechanism comprises L shaped pressing plate, rotating shaft, bolt, nut;
Wherein said L shaped pressing plate comprises the first pressure arm and the second pressure arm that mutually crosses, the intersection of described the first pressure arm and the second pressure arm is provided with opening and limited step, the step surface of this limited step is towards the outside of L shaped pressing plate, described rotating shaft places on the limited step, after the threaded portion of described bolt runs through described opening and rotating shaft, match with described nut.
Adopt after the said structure, when clamping mold, at first rotating shaft terminal is placed on the limited step, the head of bolt blocks workbench, after the threaded portion of bolt passes the middle perforation of rotating shaft and opening, mould is placed between pressure arm and the workbench, pass an end of rotating shaft with the nut screwing clamping bolt, thereby realize the Quick-clamped of mould.
L shaped pressing plate corner described in the utility model forms two angles, is defined as the inboard of L shaped pressing plate less than a side of 180 °, is defined as the outside of L shaped pressing plate greater than a side of 180 °.
Described limited step is positioned at the end face of intersection of the first pressure arm and the second pressure arm or the inwall of described opening.
The contact-making surface of described limited step and rotating shaft is cambered surface, and in use, for the mould of different-thickness, the contact point of rotating shaft and limited step is understood corresponding change, adjusts the stressing conditions of each parts, makes each parts stressed evenly.
Described limited step is made as two groups, lay respectively on the first pressure arm and the second pressure arm, and every group of limited step includes two limited steps, described two limited steps lay respectively at the relative both sides of described opening inwall, the limited step that arranges like this can be adjusted the position of rotating shaft flexibly to reach better clamping effect when the mould of clamping different-thickness.
Described L shaped pressing plate is structure as a whole, and has improved the bulk strength of L shaped pressing plate, is convenient to simultaneously processing.
The length of described the first pressure arm when two pressure arms are not isometric, can be turned use greater than the length of the second pressure arm, and namely the location swap of the first pressure arm and the second pressure arm can realize that within the specific limits clamping thickness is adjustable.
The end of described L shaped pressing plate is provided with anti-skidding projection, and this anti-skidding projection is positioned at the end that L shaped pressing plate and mould contact with workbench, and the frictional force between increase and mould and the workbench plays stable, anti-skidding effect.
Described anti-skidding projection is the strip bulge that is arranged in parallel, and this structure makes between L shaped pressing plate end and mould and the workbench larger frictional force, keeps the stability of mould.
Described the first pressure arm and the second pressure arm angulation are 90 °～120 °, in this angular range, can guarantee that lever rule is well used, and both are not easy to clamping mold at folded angle too small, the L shaped pressing plate of the excessive then easy damage of angle.
Described the first pressure arm and the second pressure arm angulation are 100 °.
Mould quick clamping mechanism of the present utility model, along with the tightening of nut, screwing force is to be delivered on the mould by rotating shaft, L-type pressing plate, thereby makes L-type pressing plate automatic impaction mould during use; This clamp mechanism takes full advantage of lever principle by adopting L shaped pressing plate that mould is fixed, and the pressing plate of L-type effectively combines the function of prior art center platen and cushion block.The utility model is simple in structure, and is swift to operate, can realize the quick-clamping of mould.
