Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for injection molding machines, and in particular to an oil receiving device for mold clamping lubricating oil in injection molding machines. Background Technology

[0002] The oil baffle device of the existing injection molding machine is generally a 20x4mm oil baffle strip fully welded around the machine body to prevent lubricating oil from overflowing. The oil receiving device is also installed on the machine body by full welding. The full welding installation method for installing oil baffle and oil receiving devices results in slow production speed, long cycle time, easy to have welding pores, resulting in oil leakage, and grinding is required after welding, which is not environmentally friendly. Due to the heat effect of full welding, the machine body is prone to deformation, affecting the appearance of the machine body. Utility Model Content

[0003] The present invention addresses the aforementioned deficiencies by providing an optimized oil-blocking and oil-receiving device for injection molding machine bodies. This device utilizes a plate-folding design, integrating multiple parts into a single component through a steel plate bending process. This reduces the need for full welding and grinding, improves production efficiency, and achieves rapid spot welding installation.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A lubricating oil receiving device for injection molding machine mold clamping includes an injection molding machine mold clamping body and an upper shell located below the injection molding machine mold clamping body. The injection molding machine mold clamping body has a moving platen in the middle. The upper shell is provided with an upper shell panel, which includes a fixed mold stop panel, an integrated oil guide plate, an integrated oil receiving platen, and a rear platen oil stop platen. A moving platen oil receiving platen is provided below the moving platen. The fixed mold stop panel, the integrated oil guide plate, the integrated oil receiving platen, and the rear platen oil stop platen are connected sequentially. The fixed mold stop panel and the integrated oil guide plate are inclined downwards and connected to the integrated oil receiving platen, and the rear platen oil stop platen is inclined downwards and connected to the integrated oil receiving platen. The device comprises two integrated oil-blocking and oil-guiding discs, symmetrically arranged. One end of each disc is connected to both sides of the fixed mold baffle panel, and the other end is connected to both sides of the integrated oil-blocking and oil-receiving disc. Each integrated oil-blocking and oil-guiding disc has an oil-blocking inclined surface and an oil-guiding groove on both sides, with an oil-guiding inclined surface between the oil-blocking inclined surface and the oil-guiding groove. A gap is provided between the two integrated oil-blocking and oil-guiding discs as a drop hopper. The moving platen oil-receiving disc is fixed below the moving platen and is inclined. The oil outlet of the moving platen oil-receiving disc is at its lower end and faces the integrated oil-blocking and oil-receiving disc. When the moving platen moves with the moving platen, the moving platen oil-receiving disc blocks the drop hopper below.

[0006] The guide rails and guide plates of the injection molding machine's moving template require a large amount of lubricating oil, mainly including lubricating oil for the mold sliding block, tie rod, toggle pin, and rear mold sliding block. This lubricating oil needs to be collected and recycled in an orderly manner in the machine body's oil collection tray. This invention uses a fixed mold stop panel, an integrated oil guide plate, and a moving template oil collection tray to receive the overflowing lubricating oil from the mold sliding block; an integrated oil guide plate and a moving template oil collection tray to receive the overflowing tie rod lubricating oil; a moving template oil collection tray and an integrated oil guide plate to receive the overflowing toggle pin lubricating oil; and a rear template oil guide plate to receive the overflowing rear mold sliding block lubricating oil. All overflowing lubricating oil is collected in the integrated oil guide plate.

[0007] As a preferred embodiment of this utility model, the fixed mold baffle panel is provided with an oil-blocking edge in the middle of the connection end with the two integrated oil-blocking and oil-guiding plates, and the two sides are respectively connected to the two integrated oil-blocking and oil-guiding plates. The connection between the fixed mold baffle panel and the integrated oil-blocking and oil-guiding plates is superimposed on the upper side of the integrated oil-blocking and oil-guiding plates.

[0008] As a preferred embodiment of this utility model, one end of the integrated oil-blocking and receiving plate is connected to two integrated oil-blocking and guiding plates, and the other end is connected to the rear template oil-blocking plate. The middle part of the integrated oil-blocking and receiving plate is an oil-receiving plate. The middle part of the connection end between the integrated oil-blocking and receiving plate and the two integrated oil-blocking and guiding plates is provided with an end oil-blocking edge. The two sides of the integrated oil-blocking and receiving plate are provided with side oil-blocking edges. At the connection point between the integrated oil-blocking and receiving plate and the rear template oil-blocking plate, and at the bottom of the side oil-blocking edges, there are oil-receiving and guiding inclined surfaces connecting the oil-receiving plate. An oil drain nozzle is provided on the side of the oil-receiving plate near the rear template oil-blocking plate, and the oil-receiving plate is inclined towards the oil drain nozzle. All leaked lubricating oil is collected in the integrated oil-blocking and receiving plate and discharged to the outside through the oil drain nozzle.

[0009] In a preferred embodiment of this invention, the bottom of the drain nozzle is connected to an L-shaped copper grease fitting. The L-shaped copper grease fitting is used to connect to an oil pipe to discharge lubricating oil to a distant location.

[0010] As a preferred embodiment of this utility model, the connecting end of the rear template oil baffle and the integrated oil baffle and receiving plate is provided with a downwardly extending rear template oil guiding slope, the rear template oil guiding slope covers the integrated oil baffle and receiving plate, the rear template oil baffle is provided with upwardly extending oil guiding side edges on both sides, and the rear template oil baffle is provided with an oil blocking edge at the end away from the integrated oil baffle and receiving plate.

[0011] As a preferred embodiment of this utility model, the movable oil receiving tray of the moving template is connected to the bottom of the moving template through multiple columns. The movable oil receiving tray of the moving template is inclined downward towards the integrated oil blocking tray. The movable oil receiving tray of the moving template has an oil blocking edge on its side and an oil leakage notch on the side facing the integrated oil blocking tray.

[0012] This invention employs a plate bending process, reducing full welding and grinding, improving production efficiency, and achieving rapid installation via spot welding. By bending the steel plate, multiple parts are integrated into a single component, reducing machine body deformation and increasing the strength of the steel plate, thereby enhancing the overall machine body strength. The oil receiving method uses a beveled design, allowing lubricating oil to flow orderly into the drain nozzle. Since injection molding machines come in various specifications and sizes, using molds to press out beveled shapes is too costly and has poor adaptability. Therefore, bending into a beveled shape is the key feature of this invention. Bending reduces welding and allows for installation via spot welding. Replacing welded edges with bent edges makes cleaning convenient and quick, eliminating unsanitary corners.

[0013] The beneficial effects of this utility model are: by adopting a plate bending method, multiple parts are integrated into one part through the process of bending steel plates, reducing full welding and grinding, improving production efficiency, and achieving the purpose of rapid spot welding installation.
