Abstract

The utility model discloses an upper cover for a die assembly oil cylinder. The upper cover comprises a cover body with a circular truncated cone at the bottom, and a secondary cylinder rod threaded with the circular truncated cone, wherein a die assembly secondary cylinder air inlet I communicated to the axial center of the cover body is formed in the side surface of the cover body, a die assembly secondary cylinder air inlet II is formed in the axial center of the secondary cylinder rod, the die assembly secondary cylinder air inlet I is communicated with the die assembly secondary cylinder air inlet II, and an L-shaped die assembly main cylinder air inlet is downwards formed in the side surface of the cover body. The upper cover comprises the cover body and the secondary cylinder rod which can be dismantled, the die assembly secondary cylinder air inlets originally formed in a cylinder lower mould plate are formed in the secondary cylinder rod, thus the phenomenon that oil pipes connected to the die assembly secondary air inlets are broken to leak oil because of reciprocating with the cylinder lower mould plate for a long time is avoided, and in addition, the cover body and the secondary cylinder rod are separately machined, thus raw materials can be saved.

The disclosed injection machine die cylinder of prior art, the sub-cylinder fuel feed hole of matched moulds is arranged on the cylinder lower bolster, is connected to oil pipe on the sub-cylinder fuel feed hole of matched moulds because with the cylinder lower bolster, moving reciprocatingly for a long time, the phenomenon of jackknifing leakage of oil easily occurs.
In addition, the disclosed die cylinder upper cover of prior art, sub-cylinder bar and lid are integrated, adding brigade cylinder bar structure will waste a large amount of raw material.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of die cylinder upper cover, stops oil pipe because rocking the purpose that causes the jackknifing oil leakage phenomenon to occur to reach.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of die cylinder upper cover, comprise that bottom is provided with the lid of round platform, and and the sub-cylinder bar that is threaded of described round platform, on described lid side, offer the sub-cylinder fuel feed hole one of matched moulds that passes to place, described lid axle center, described sub-cylinder bar shaft core position offers the sub-cylinder fuel feed hole two of matched moulds, the sub-cylinder fuel feed hole one of described matched moulds and the sub-cylinder fuel feed hole two of described matched moulds are connected, and on described lid side, also offer the female cylinder fuel feed hole of L-type matched moulds downwards.
Preferably, described lid end face central authorities are provided with the thimble oil cylinder seat.
Preferably, described lid side is provided with thimble oil cylinder oil inlet hole.
Preferably, on described lid side, also be provided with thimble oil cylinder oil outlet.
Preferably, described frustum cone side is provided with a circle O type oil sealing.
Pass through technique scheme, a kind of die cylinder upper cover that the utility model provides comprises lid and the sub-cylinder bar that can split, and be provided with thereon and originally be arranged on the sub-cylinder fuel feed hole of matched moulds on the cylinder lower bolster, the oil pipe of having stopped to be connected on the sub-cylinder fuel feed hole of matched moulds moves reciprocatingly and the phenomenon of jackknifing leakage of oil with the cylinder lower bolster because of long-term.
The accompanying drawing explanation
