Abstract
The utility model discloses an add the oil circuit structure of differential valve on mode locking combination jar die sinking loculus, realize the die sinking loculus oil of combination jar, it is differential to carry out the mode locking simultaneously with the die sinking loculus oil greatly, its characterized in that: the existing mold opening small cavity oil of the mold locking combined cylinder is led to an oil return pipeline and is switched into an additionally arranged differential valve, so that the control can be realized through the valve, the existing mold opening small cavity oil returning to the oil return pipeline enters a mold locking cavity, and the mold locking differential motion is synchronously carried out with the mold opening large cylinder cavity oil, so that the requirement of high-speed movement of the movable plate is met.
Description
Technical Field
The utility model relates to a mode locking oil circuit structure for hydraulic mechanical equipment combination mode locking jar is used for realizing the little jar oil of die sinking, also carries out differential with the mode locking jar in step to satisfy the needs of the higher-speed motion of movable plate.
Background
At present, hydraulic mechanical equipment adopting a combined mold locking cylinder is only provided with a differential valve on an oil way of a large cavity for mold opening to realize differential motion with mold locking, so that the differential motion of the existing mold locking combined cylinder cannot meet the requirement of high speed of a movable plate, thereby influencing the production efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a mode locking combination jar die sinking loculus on, add the oil circuit structure that the differential valve satisfied the high-speed motion of movable plate to the defect that prior art exists.
The above purpose is realized by the following technical scheme:
the utility model provides an add the oil circuit structure of differential valve on mould locking combination jar die sinking loculus, only add the differential valve on the little jar chamber oil circuit of die sinking, its characterized in that: the existing mold opening small cavity oil of the mold locking combined cylinder is led to an oil return pipeline and is switched into an additionally arranged differential valve, so that the control can be realized through the valve, the existing mold opening small cavity oil returning to the oil return pipeline enters a mold locking cavity, and the mold locking differential motion is synchronously carried out with the mold opening large cylinder cavity oil, so that the requirement of the movable plate for higher-speed movement is met.
This oil circuit structure's advantage: the mold locking speed can be increased by adopting the existing hydraulic mechanical equipment such as a three-plate injection molding machine, a die casting machine, an oil press and the like with a mold locking combined oil cylinder, and a certain energy-saving effect can be achieved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
the mold opening device comprises a mold opening small cavity differential valve (03-2B 12A model), a mold opening large cavity differential valve (04-2B 12A model), a mold locking valve (04-3C 2 model), a 4-mold locking cavity, a 5-mold locking piston, a 6-mold opening large cavity, a 7-mold opening small cavity, an 8-large piston rod, a 9-movable plate, a 10-three-plate mold locking mechanism and a 11-mold locking cylinder, wherein the mold opening small cavity is formed by a mold opening small cavity differential valve (03-2B 12A model), the mold locking piston is arranged in the mold.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, during operation, the mold clamping valve 3 is electrically connected to the two holes P and a, the mold opening large cavity differential valve 2 (04-2B 12A type) is electrically connected to the two holes T1 and B1, and the mold opening small cavity differential valve 1 (03-2B 12A type) is electrically connected to the two holes T2 and B2, and then the working pressure oil P enters the mold clamping cavity 4 through the hole 3A of the mold clamping valve (04-3C 2 type), because the mold clamping cavity has a larger cross-sectional area than the sum of the mold opening large cavity and the mold opening small cavity, the mold clamping piston 5 is pushed to move right under the action of the differential force, so that the oil in the mold opening large cavity and the mold opening small cavity is forced to enter the hole B1 through the hole T1 of the mold opening large cavity differential valve 2 (04-2B 12A type) and the hole T2 of the mold opening small cavity differential valve 1 (03-2B 12A type) to the hole B2, and the mold opening large cavity and the mold opening small cavity are simultaneously, and the differential mode of the mold opening large cavity and the mold, the moving plate 9 is pushed via the large piston rod 8 to move to the right at a higher speed.
Additionally, the utility model provides a clamping cylinder and three board-like clamping mechanism are current product, add on this application based on the basis of current product, so the structure and the theory of operation of this current product do not do detailed description, can learn according to current product description or ordinary technical manual.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
