Abstract
The invention discloses a cooling water ring device for an injection mold, belonging to the technical field of molds. The device mainly comprises a fixed hot nozzle body, a cooling water ring body, an external pressure sealing rubber ring, an internal pressure sealing rubber ring, a common sealing rubber ring and the like, wherein the internal pressure sealing rubber ring is in surface contact with the outer wall and the root of an internal pressure rubber ring sealing column, and is in surface contact and seal fit with the cooling water ring body; the external pressure sealing rubber ring is in surface contact with the inner ring and the bottom of an external pressure sealing rubber ring groove, and is in surface contact and seal fit with the cooling water ring body; the fixed hot nozzle body is in threaded fit with the cooling water ring body and is sealed through welding spots. Natural water flows into a ring-shaped cavity through a water inlet passage hole in order to cool the periphery of the hot nozzle, and then flows out of the cooling water ring device through a water outlet passage hole; the cooling water ring device can rapidly absorb the heat at the periphery of the hot nozzle without local water stagnation, thus solving the undesirable situations of flow mark, gas mark and wire drawing derived from the fact that the surface temperature of the product is difficult to control.
Description
Technical field
The invention belongs to technical field of mold, 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.
Summary of the invention
In view of above problem points; The technical problem that the present invention 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; 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.
Technical scheme of the present invention 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 present invention realizes 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; 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; Do not have local dead water phenomenon, solved the difficult control of product surface Yin Wendu and the bad phenomenon such as current mark, gas line and wire drawing of appearance, the requirement of assurance product size; Reduce cost, improved production efficiency.
