Abstract
A kind of oil cylinder cooling structure of the present invention, oil cylinder and the seat that catchments including cover half bottom, wherein：Oil cylinder is connected with coldplate, cover half is connected by coldplate, and coldplate is equipped with cooling tube, and cooling tube is equipped with inlet and outlet, and inlet and outlet connect the seat that catchments by water inlet pipe, outlet pipe respectively.The present invention provides a kind of oil cylinder cooling structure, and realizing reduces cooling plate temperature, the heat transfer of cover half is avoided to the purpose of oil cylinder, so as to extend the service life of oil cylinder.
Description
Technical field
The present invention relates to a kind of oil cylinder cooling structures.
Background technology
Cover half bottom oil cylinder due to being close to temperature is caused to be difficult to dissipate with die casting machine machine plate, high temperature causes inside oil cylinder
Seal groove shrink, cause logical cylinder.Therefore, how to solve the above problems, become urgent problem to be solved.
Invention content
The present invention provides a kind of oil cylinder cooling structure for problem above, and realizing reduces cooling plate temperature, avoids cover half
Heat transfer to oil cylinder purpose, so as to extend the service life of oil cylinder.
In order to solve the above technical problems, a kind of oil cylinder cooling structure, oil cylinder and the seat that catchments including cover half bottom, wherein：
Oil cylinder is connected with coldplate, cover half is connected by coldplate, and coldplate is equipped with cooling tube, and cooling tube is equipped with water inlet and water outlet
Mouthful, inlet and outlet connect the seat that catchments by water inlet pipe, outlet pipe respectively.
Due to the adoption of the above technical scheme, coldplate is arranged between oil cylinder and cover half the present invention, and the heat on cover half leads to
Supercooling plate is transferred to oil cylinder, is equipped with cooling tube in coldplate, the inlet and outlet of cooling tube are connected respectively by pipeline
Catchment seat, and the water in the seat that catchments flow to cooling tube by water inlet pipe, reduces the temperature of coldplate, and the water after heat exchange passes through water outlet again
Mouth and outlet pipe flow back to the seat that catchments, and form cycle, take away cover half by the recirculated cooling water in cooling tube and be transmitted to coldplate
Heat avoids the heat transfer of cover half to oil cylinder, so as to extend the service life of oil cylinder.
A kind of above-mentioned oil cylinder cooling structure, oil cylinder are equipped with piston and end cap, and piston is connected with piston rod, piston and end cap
It is respectively equipped with sealing ring connection oil cylinder.The heat that cover half is transmitted to coldplate is taken away by the recirculated cooling water in cooling tube, is kept away
Exempt from the sealing ring on piston and end cap to be heated after-tack, cause logical cylinder.
A kind of above-mentioned oil cylinder cooling structure, cooling tube distribute as net shape in coldplate.It is fixed to take away to greatest extent
Mould is transmitted to the heat of coldplate.
A kind of above-mentioned oil cylinder cooling structure, inlet and outlet are arranged on coldplate side, and cover half is equipped with vertical logical
Hole, water inlet pipe, outlet pipe are arranged in vertical through holes.
A kind of above-mentioned oil cylinder cooling structure, coldplate are the installation form of oil cylinder, coldplate one end connection oil cylinder and end
Lid, other end connection cover half, coldplate are threaded through with being equipped with axis hole, piston rod in the middle part of end cap in axis hole, and cooling tube annulate shaft hole is set
It puts.
Description of the drawings
The present invention is described in further detail below in conjunction with the embodiment in attached drawing, but is not formed to the present invention's
Any restrictions.
Fig. 1 is the structure diagram of the present invention；
The A that Fig. 2 is Fig. 1 goes out enlarged structure schematic diagram；
Fig. 3 is the attachment structure schematic diagram of coldplate and water inlet pipe of the present invention, outlet pipe.
Specific embodiment
As shown in Figures 1 to 3, a kind of oil cylinder cooling structure of the invention, oil cylinder 2 and the seat that catchments including 1 bottom of cover half,
In：Oil cylinder 2 be connected with coldplate 3, by coldplate 3 connect cover half 1, coldplate 3 be equipped with cooling tube 31, cooling tube 31 be equipped with into
The mouth of a river 32 and water outlet 33, water inlet 32 and water outlet 33 connect the seat that catchments by water inlet pipe 4, outlet pipe 5 respectively.
Oil cylinder 2 is equipped with piston 21 and end cap 22, and piston 21 is connected with piston rod 23, and piston 21 and end cap 22 are respectively equipped with close
Seal 24 connects oil cylinder 2.
Cooling tube 31 distributes as net shape in coldplate 3.
Water inlet 32 and water outlet 33 are arranged on 3 side of coldplate, and cover half 1 is equipped with vertical through holes 11, water inlet pipe 4, water outlet
Pipe 5 is arranged in vertical through holes 11.
Coldplate 3 is the installation form of oil cylinder 2, and 3 one end of coldplate connection oil cylinder 2 connects cover half with end cap 22, the other end
1, coldplate 3 is equipped with axis hole 25 with 22 middle part of end cap, and piston rod 23 is threaded through in axis hole 25, and 31 annulate shaft hole 25 of cooling tube is set.
When the present invention is specifically used, coldplate 3 is arranged between oil cylinder 2 and cover half 1, and the heat transfer on cover half 1 is to cold
But in plate 3, the water in the seat that catchments flow to the cooling tube 31 in coldplate 3 by water inlet pipe 4, reduces the temperature of coldplate 3, heat exchange
Water afterwards flows back to the seat that catchments by water outlet 33 and outlet pipe 5 again, forms cycle, passes through the recirculated cooling water band in cooling tube 31
The heat that cover half 1 is transmitted to coldplate 3 is walked, avoids the heat transfer of cover half 1 to oil cylinder 2.
In conclusion the present invention such as specification and diagramatic content, is made actual sample and through test is used for multiple times, from making
It is seen with the effect of test, the provable present invention can reach its desired purpose, and practical value is unquestionable.It is provided above
