Description

Clamping mold clamping force, mold thickness are adjusted structure

Technical field:

The utility model relates to the used equipment of a kind of blowing moulding, particularly a kind of unlatching, closure or clamping device.

Background technology:

At food; in the industries such as cosmetics; extensively adopt hollow molding blow moulding machine packing manufactured goods; existing hollow molding blow moulding machine; the closure of its mould; unlatching is finished by the reciprocating motion of clamping; the power of its motion mostly is to adopt hydraulic driving mode; promptly the execution oil cylinder by hydraulic system promotes opening of clamping; close; but there is environmental pollution in hydraulically powered clamping; safeguard problems such as the impact of inconvenience and transmission of power is bigger; pollution will influence goods user's health and safety; safeguard and time-consumingly will improve cost of manufacture; the power stationarity will influence quality of item; at above-mentioned situation; the dealer develops a kind of electrodynamic mechanical type clamping, and this mechanism does not re-use fluid as working medium, has fundamentally overcome the defective that the hydraulic-driven clamping brings.But; the mechanical type clamping; the reciprocating displacement of its member is a definite value; template also is a definite value with the suffered active force (mold clamping force) of the closed terminal point of motion of member; it is the clamping of general mechanism structure; its mold clamping force is unmodifiable definite value; thereby will limit the performance of this body function, and when the mold clamping force of clamping can not value up to specification, overlap promptly can appear in the goods of blow molding; defectives such as burr; even operation can't be carried out; in addition, because the clamping displacement is a definite value, when reality is used; the thickness of template construct may produce error; thickness is excessive or too small, all can make the location after the mould closure, can't reach predetermined value and can't carry out the blowing operation; therefore, suitably to adjust its displacement be problem demanding prompt solution to the mechanical type clamping.

The utility model content:

Technical problem to be solved in the utility model is; provide a kind of clamping mold clamping force, mold thickness to adjust structure; it can adjust the relative distance between front template and the inner formword, can guarantee the quality of blowing operation, can avoid template thickness error effect blowing operation normally to carry out again.

The technical scheme in the invention for solving the above technical problem is:

Be provided with one between back link and the rear pattern plate and adjust structure, adjust structure and have inclined board and declined board, the oblique top face of the inclined end face of inclined board and declined board touches, the stretch through through hole of inclined board and the microscler through hole of declined board of one group of screw is rotated with at rear pattern plate, and the end of declined board 14 is provided with the adjustment member.But adjust member push-and-pull declined board, the effect on mat inclined-plane, change the position of the relative rear pattern plate of inclined board, the back link position that is articulated in inclined board changes thereupon, and two connecting rods and slide and inner formword etc. are mechanical connection, and its relative position is fixed, therefore, the inclined-plane moves the relative position that can change between front template and the inner formword, realizes adjusting function.

The utility model is adjusted function with it; cooperate with pre-pressing structure on the inner formword; can make mold clamping force reach setting; to guarantee that blow-molded article does not produce overlap, burr; and it is adjusted and can avoid the mold thickness error that mould can't be used equally or owing to bring problem such as bad goods, thereby guarantees that the mechanical type clamping can be widely used in industries such as food, cosmetics.
