Problems solved by technology
[0004] The purpose of the present invention is to solve the problem that the lubricating oil in the connection part of the traditional injection molding motorized template and the tie rod is uncontrollably leaked, so that the large plane of the movable template mold is polluted. In the oil groove in the mold shifting guide sleeve, due to the movement of the movable platen, the lubricating oil is taken out of the oil groove, and the leaked lubricating oil is effectively exported, which greatly improves the cleanliness of the large plane of the movable platen mold installation.

The invention provides a lubricating structure for a pull rod and a moving mold guide sleeve of an injection molding machine. The lubricating structure comprises an injection molding machine moving mold plate, the moving mold guide sleeve, a dustproof ring, a moving mold plate gland, screws and the pull rod. Pull rod through holes are formed in the moving mold plate, the moving mold guide sleeve is arranged on the inner sides of the pull rod through holes, and the moving mold guide sleeve is connected and fixed in the pull rod through holes through the moving mold plate gland by using the screws. An annular lubricating oil collecting groove is formed in the moving mold plate gland, and a downward oil leakage hole and an inclined oil guide hole are formed in the bottom of the collecting groove. Half-moon-shaped oil collecting grooves are formed in the lower sides of the inner walls of the pull rod through holes of the injection molding machine moving mold plate, and the bottoms of the oil collecting grooves communicate with leaked oil guiding-out holes drilled in the surface of the injection molding machine moving mold plate. Lubricating oil for connecting the injection molding machine moving mold plate and the pull rod is stored in a spiral oil groove in the moving mold guide sleeve, after the lubricating oil is taken out of the oil groove, the leaked lubricating oil is effectively guided out through the structural design of the lubricating structure, and cleanliness of a large mold mounting plane of the moving mold plate is greatly improved.
Description
technical field [0001] The invention relates to the technical field of connection lubrication between a movable template of an injection molding machine and a tie rod, in particular to a lubricating structure for a mold moving guide sleeve of a tie rod of an injection molding machine. Background technique [0002] The moving mold guide sleeve is used to realize the sliding connection between the movable template and the tie rod in the injection molding machine. The lubricating oil is injected into the parts that need to be lubricated through the lubricating oil filling port on the movable template. The lubricating oil is stored in the oil groove inside the mold shifting guide sleeve. When the lubricating oil is filled too much, it will overflow from the oil groove, and flow to the moving template gland through the large end face of the mold shifting guide sleeve. If it accumulates too much, it will Uncontrollable overflow from the gap between the tie rod and the movable temp...
