Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding machine lubrication, and particularly relates to a structure device of an oil retaining and oil tray for the hinge of an injection molding machine. Background Art
[0002] The hinge connection part is an important part of mechanical equipment and is also a vulnerable part. Taking an injection molding machine as an example, large and small pin shafts, threaded sleeves, wire rods, etc. are the connecting parts of the injection molding machine. Once worn, especially the large pin shaft is worn, it will cause the imbalance of the three plates. In the light case, flash will appear on the products, and in the heavy case, the template and tie rods will break.
[0003] In the prior art, the lubricating oil injection pump is set through the PLC on the equipment to inject oil and lubricate the mechanical connection parts that need lubrication on the equipment at regular intervals and fixed opening modules. The overflowing oil flows from top to bottom from each lubricating part to the frame, oil tank or oil tray. During the injection molding process, small plastic products with multiple cavities in one mold, plastic heads, etc. are easy to bounce onto the oil tank and oil tray, and the mold water, impurities, dirt are mixed with the lubricating oil, resulting in the accumulation of oil dirt on the oil tank, oil tray and frame. The return oil cannot flow back to the waste oil collection bucket smoothly and overflows on the workshop floor, seriously polluting the environment and wasting manpower and material resources. It also requires manual addition of lubricating oil and treatment of waste oil. Due to the above various factors, machine users or workshop managers mostly reduce the lubrication frequency, which in turn accelerates the wear of the hinge and reduces the utilization rate of the equipment. Summary of the Utility Model
[0004] Therefore, the utility model provides a structure device of an oil retaining and oil tray for the hinge of an injection molding machine to solve the above problems in the prior art.

[0023] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] As Figures 1 to 5 shown, a structure device of an injection molding machine hinge lubricating oil retaining and oil pan for the first aspect embodiment of the present utility model includes:
[0025] The hinge and the connecting rod are connected in a left-right structure manner. The connecting rod and the bracket are respectively connected by six large pin shafts, four small pin shafts, two guide rods, as well as a front connecting rod, a rear connecting rod, a front bracket, a rear bracket, a small connecting rod, a thrust seat, a moving template 10, a rear template 11, and a tie rod 12; a left front oil retaining plate 1, a left rear oil retaining plate 2, a right front oil retaining plate 3, and a right rear oil retaining plate 4. The left front oil retaining plate 1 and the right front oil retaining plate 3 are respectively inside the left rear oil retaining plate 2 and the right rear oil retaining plate 4, and are installed and fixed on the left and right sides of the moving template 10. The left rear oil retaining plate 2 and the right rear oil retaining plate 4 respectively form a partial double layer outside the left front oil retaining plate 1 and the right front oil retaining plate 3, and are respectively installed and fixed on the left and right sides of the rear template 11. The lower parts of the left front oil retaining plate 1, the left rear oil retaining plate 2, the right front oil retaining plate 3, and the right rear oil retaining plate 4 are folded at 90°, and the width of the folded edge above the tie rod exceeds the tie rod 12. Adopting such a structure and manner to ensure that the lubricating oil on the left-right structure connecting rod bracket is blocked by the left front oil retaining plate 1, the left rear oil retaining plate 2, the right front oil retaining plate 3, and the right rear oil retaining plate 4 from overflowing towards the center of the machine. The bottom front oil pan 5 is installed and fixed at the front bottom of the moving template 10. The bottom rear oil pan 6 is installed at the rear bottom of the rear template through the left and right channel rails of the second oil pan bracket 8 and the first oil pan bracket 7. The first oil pan bracket 7 is installed and fixed below the thrust seat stop plate. The second oil pan bracket 8 is respectively installed and fixed under the left and right of the rear template. The bottom front oil pan 5 and the bottom rear oil pan 6 partially overlap. The bottom front oil pan 5 and the bottom rear oil pan 6 are folded with double edges and have slopes in the front and rear directions. There is an oil return joint screw hole 9 at the rear end of the bottom rear oil pan 6. The oil return screw hole is equipped with a joint, and the oil return joint screw hole 9 is connected to the oil return joint.

[0026] The lubricating oil is pressurized and transported by a lubricating oil injection pump, and is injected and lubricated through a lubricating oil pipe, a lubricating oil distributor, and the upper oil nozzles of six large pin shafts, four small pin shafts, and two guide rod sleeves on the left and right sides. <The internal structures between the pin shafts and the steel sleeves and copper sleeves are not described one by one here>. The lubricating oil flows from top to bottom to lubricate the lubrication parts required. The oil overflowing from each lubrication part smoothly flows to the front oil tray 5 at the bottom and the rear oil tray 6 at the bottom through the blocking and guiding of the left front oil baffle 1, the left rear oil baffle 2, the right front oil baffle 3, and the right rear oil baffle 4, and returns to the lubricating oil tank through the oil return joint screw hole 9, the joint, the oil return pipe, and the oil return joint, and is recycled after sedimentation and filtration.
[0027] The technical effects achieved by the above embodiments are as follows: The machine hinge and the connecting rod connection adopt a left-right structure, and the left and right sides are respectively enclosed by the left front oil baffle 1, the left rear oil baffle 2, the right front oil baffle 3, the right rear oil baffle 4, the front oil tray 5 at the bottom, and the rear oil tray 6 at the bottom. Adopting such a structural method can ensure that the lubricating oil return flows smoothly back to the lubricating oil tank without overflowing, and plastics, impurities, mold water, dust, etc. will not mix into the lubricating oil, and the purity of the lubricating oil return is always maintained.
