Description
Technical field
The utility model belongs to technical field of mold, and the cooling water loop device that a kind of mould is used relates in particular in the injection mold that contains TOP-TIP.
Background technology
At present for the injection mold that TOP-TIP is arranged; The temperature of main cast gate, flow distribution plate and hot mouth is to carry out temperature control through the hot flow path temperature controller; What inlay that the template of main cast gate, flow distribution plate and hot mouth adopts is that nature water cools off, and adopts mold temperature to regulate machine template is carried out temperature control.
When mould and hot flow path carry out temperature control; Most critical be to carry out the quality that effective temperature control could guarantee product around the hot mouth to hot flow path, traditional way is direct in hole, processing linear type water route on the template or direct hole, processing linear type water route in die insert.Hole, this water route is easy to process, but limited by its processing method, can only carry out temperature control to hot mouth two sides, and can not all carry out temperature control to the hot mouth environment temperature of hot flow path.Will cause inhomogeneous cooling even like this, defective such as product has water wave, wire drawing in injection moulding process, and it is flat to contract, and also mould is when long-term work, and current at a high speed can corrode hole, template water route inwall, change template or die insert expensive.
In the recent period domestic way adds cooling jacket for giving hot mouth, but the not mentioned cooling problem of how optimizing to the position that hot mouth contacts with water jacket, and is confined to the hot mouth of needle valve, not mentioned during to three template die hot flow paths commentaries on classics cold runner cooling jacket how to prevent the problem of pulling.
The utility model content
In view of above problem points; The technical problem that the utility model will solve is the cooling water loop device that is installed on the mould template or in the die insert through a kind of; Hot mouth environment temperature is effectively controlled, and this device can be used on the focus formula, in the TOP-TIPs such as needle valve; Also can be used for three template die hot flow paths changes in the cold runner structure, prevents that stripper plate from pulling the cooling water ring.
The technical scheme of the utility model is:
The cooling water loop device comprises stationary heat mouth body 9, cooling water ring body 12, external pressure sealing rubber ring 18, inner pressuring sealing rubber ring 19 and conventional seals rubber ring 21.
Stationary heat mouth body 9 is provided with into hole, water water route 2, hole, water outlet water route 7, conventional seals rubber ring standing groove 1; Hot mouth putting hole 8, hot mouth fine positioning hole 6, ring 4 in the taper heat of cooling mouth water route; Fine positioning is flat 11, and interior pressure seal with elastometic washer post 5 is fixing with screwed hole 10 and external screw thread 3 compositions.
Cooling water ring body 12 is provided with external pressure caulking gum ring recess 14, taper heat of cooling mouth water route outer shroud 15, anti-taper locating ring 16 and internal thread 13 compositions pulled.
Inner pressuring sealing rubber ring 19 is that face contacts with interior pressure seal with elastometic washer post 5 outer walls and root, with cooling water ring body 12 for face contacts, be sealed and matched.Ring is that face contacts with bottom land in external pressure sealing rubber ring 18 and the external pressure caulking gum ring recess 14, and cools off water ring body 12 for face contacts, and is sealed and matched.Conventional seals rubber ring 21 contacts with 1 of conventional seals rubber ring standing groove, is sealed and matched.External screw thread 3 in the stationary heat mouth body 9 is connected with cooling water ring body 12 interior internal threads 13 and is fastening, seals through pad 17 and pad 20.Fixingly being threaded with template backing plate groove or fixed die insert groove with screwed hole 10 in the device, vertically to fixing, fine positioning flat 11 and template backing plate groove or fixed die insert groove closely cooperate, and be parallel to fixedly positioning.After the cooling water loop device was fixing, hot mouth 22 of focus formula or the hot mouth 23 of needle valve were put in the hot mouth putting hole 8, and the sealing portion of hot mouth and hot mouth fine positioning hole 6 closely cooperate.Hot flow path changes in the cold runner three template die structures, and anti-taper locating ring 16 inclined-planes of pulling are that line contacts with the interior inclined-plane of stripper plate.
Nature water flows in the annular chamber of ring 4 and 15 formation of taper heat of cooling mouth water route outer shroud in the taper heat of cooling mouth water routes through back, water inlet hole, water route 2; Carry out cooling off around the hot mouth; The 7 outflow cooling water loop devices from hole, water outlet water route are realized the cooling effect to hot mouth then.
The beneficial effect that the utility model is realized is the cooling water loop device of processing through the carbon steel that uses hard high-strength; After making nature water through this device; Can absorb the heat of hot mouth periphery rapidly, the high-velocity flow in the ring of taper heat of cooling mouth water route can be controlled the temperature at place, hot mouth fine positioning hole uniformly, does not have local dead water phenomenon; The bad phenomenon such as current mark, gas line and wire drawing that solved the difficult control of product surface Yin Wendu and occurred; Guarantee the product size requirement, reduce cost, improved production efficiency.
