SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the special mould for producing the sealing ring is provided, and the injection molding cooling efficiency of the sealing ring can be improved.
The technical scheme of the utility model is that: a special mould for producing a sealing ring comprises an upper mould plate and a lower mould plate, wherein the upper mould plate comprises an upper mould forming plate and an upper mould sealing plate, the lower mould plate comprises a lower mould forming plate and a lower mould sealing plate, a plurality of first annular grooves are uniformly arranged on the forming end surface of the upper mould forming plate, a second annular groove is arranged on the back surface of the forming end surface of the upper mould forming plate corresponding to each first annular groove, the first annular grooves are coincided with the central axes of the corresponding second annular grooves, a first water channel is processed on the back surface of the forming end surface of the upper mould forming plate and is communicated with the second annular grooves, a third annular groove is arranged on the forming end surface of the lower mould forming plate corresponding to each first annular groove on the forming end surface of the upper mould forming plate, and the central axes of the first annular grooves and the corresponding third annular grooves are coincided, the back of lower mould profiled sheeting shaping terminal surface corresponds each third annular groove all sets up a fourth annular groove, the third annular groove with correspond fourth annular groove the central axis coincides, the back processing of lower mould profiled sheeting shaping terminal surface has the second water course, the second water course intercommunication fourth annular groove, go up the mould closing plate with it sets up the end face contact of first water course fixed just to go up the mould closing plate with it seals to go up the mould profiled sheeting contact, the lower mould closing plate with it sets up the end face contact fixed just of second water course to go up the mould profiled sheeting lower mould closing plate with it seals to go up the mould profiled sheeting contact.
Preferably, the cross section of the second annular groove is rectangular, and the cross section of the fourth annular groove is rectangular.
When the water inlet and outlet pipe is used, the water inlet and outlet on the first water channel and the water inlet and outlet on the second water channel are respectively communicated with the water inlet and outlet pipes corresponding to the water circulation system on the injection molding machine.
The utility model has the advantages that: because the back of going up the mould profiled sheeting shaping terminal surface corresponds each first annular groove all sets up a second annular groove, the back of lower mould profiled sheeting shaping terminal surface corresponds each third annular groove all sets up a fourth annular groove, and the second annular groove passes through first water course intercommunication, and fourth annular groove passes through the second water course intercommunication, when moulding plastics, flows through the cooling water in the water course, and second annular groove and cooling water large tracts of land contact can take away the heat of the first annular groove department of cope match-plate pattern fast, and fourth annular groove and cooling water large tracts of land contact can take away the heat of lower bolster third annular groove department fast, and cooling efficiency promotes greatly, and the cooling cycle shortens.
