Description
Technical field
The utility model relates to cylinder application, particularly a kind of Novel air cylinder for injection moulding process.
Background technology
In prior art, cylinder for injection moulding process is generally independently control needle and carries out work, so often there is the nonsynchronous phenomenon of needle, cause occurring the problems such as weld mark, have impact on the shaping of product and the fraction defective that improve product, and independently control owing to have employed, each cylinder must have independently gas circuit, and then improves production and processing cost.Needle is often simply fixed on the base of cylinder body, and it is due to motion repeatedly up and down, and its shake-proof ability is more weak, and fatigue limit number of times is also lower, and then greatly reduces its service life, brings very large inconvenience to enterprise.
Utility model content
For solving Problems existing in above-mentioned background technology, the purpose of this utility model is to provide a kind of Novel air cylinder, with reach control simultaneously multi-cylinder be synchronized with the movement, reduce gas path joint use and strengthen its shake-proof ability, extend the object in its service life.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of Novel air cylinder, comprise cylinder cap plate, cylinder body, piston, needle and gas path joint, described cylinder cap plate is connected by screw with cylinder body, and described piston is arranged in described cylinder body, and described needle is arranged in described piston, and described cylinder body is at least provided with two; Described gas path joint is arranged on the side of described cylinder cap plate, the inside of described cylinder cap plate is provided with the first gas circuit and the second gas circuit, the gas outlet of described first gas circuit is arranged on the top in the middle part of described cylinder body cross section, and the gas outlet of described second gas circuit is arranged on the bottom of described cylinder body cross section dual-side; Described needle one end be placed in described piston is set to square groove structure, and described square groove structure is provided with the locating piece matched with it.
Preferably, described cylinder body is set to four.
Preferably, described needle is also provided with packing ring, described packing ring contacts with described locating piece.
Preferably, described needle is also provided with jump ring, described jump ring one end contacts with described packing ring, and the other end contacts with described cylinder body base.
By technique scheme, a kind of Novel air cylinder that the utility model provides, under multiple cylinder body is arranged on one block of cylinder cap plate simultaneously, can control being synchronized with the movement of multiple cylinder body simultaneously, and then avoids and occur the problems such as weld mark because of the asynchronous of needle; Every block cylinder cap plate only needs the gas path joint in a loop, greatly reduces the cost of its production and processing, and make its convenient disassembly, maintenance cost is low; One end due to needle is set to square groove structure, and coordinates the locating piece on it, not only increases the ability that it is shockproof, also makes its fatigue limit number of times have significant raising, and then extends its service life.
