Problems solved by technology
[0004] With the above-mentioned structure, the lubricating oil on the shaft is filled in the bushing, and after a period of operation, some metal shavings or impurities will be produced in the lubricating oil. At this time, the lubricating oil must be replaced or filtered. It can continue to be used, so the traditional way of replacing lubricating oil requires that the lubricating oil at each shaft must be replaced separately, resulting in a complicated process and a waste of time, which cannot achieve effective work efficiency

The present invention is a toggle lubricating oil circulation structure of an injection molding machine, which is composed of a toggle mechanism composed of a fixed tailstock corresponding to the upper and lower movable joint arms to push the movable mold base forward and close the fixed mold base, and The joint arms in the upper and lower movable joint arm groups are made of shaft rods pierced and pivotally connected with each other, and oil guide passages are provided in the joint arm rods of the upper and lower movable joint arm groups to lead into the shaft rods The oil through hole of the upper and lower movable joint arm groups is provided with a connecting oil pipe to communicate with the oil passage of the upper and lower movable joint arm groups at the pivoted shaft of the upper and lower movable joint arm groups. According to this, The lubricating oil flows through the pivoted shaft through the design of the oil circuit, so that it has a lubricating effect when the toggle mechanism is actuated, and at the same time, the impurities generated during the actuation can be circulated through the oil circuit to dissipate them. Bring out.
Description
technical field [0001] The present invention relates to a circulation structure of lubricating oil passages of toggle joints of injection molding machines, in particular to a kind of conducting oil passages with one in and one out in the upper and lower movable joint arm groups, so that the pivot of the toggle mechanism The shaft at the joint has a lubricating and circulating structure for injection molding machine elbow lubricating oil passages. Background technique [0002] The toggle mechanism is a very important mechanism in the injection molding machine. The two ends are respectively assembled on the corresponding side of the fixed support plate and the movable mold base to push or pull back the movable mold base in time to achieve the mold locking or mold opening. action. And in order to make each joint arm in the toggle mechanism move smoothly, the inventor has developed and researched a kind of toggle mechanism improvement (2) of the injection molding machine for th...
