Abstract
The utility model discloses a cold runner rubber injection molding die, which comprises a rubber inlet, wherein a runner plate, a cooling unit, a heat-insulating plate and a cavity plate are sequentially arranged below the rubber inlet; and a runner and the cavity plate are connected through a sprue bush. Because a circulating cooling water way used for cooling the sprue bush is arranged in the cooling unit, the temperature of a rubber material in the cooling unit is effectively reduced, a vulcanized rubber is prevented from entering a product, and the quality of a rubber product is improved. Because an upper sealing ring and a lower sealing ring are arranged on the sprue bush to seal the circulating cooling water way, the phenomenon of water leakage is avoided, and the sealing property of the sprue bush is ensured.
Description
Technical field
The utility model relates to the injection molding of rubber field, is specifically related to a kind of cold runner rubber ejection shaping die.
Background technology
Rubber not only provides daily life indispensable light industry rubber product such as daily, medical for people, and is widely used in heavy industry such as digging, traffic, building, machinery, electronics and new industry because of its excellent specific property.
At present, make rubber product and mainly adopt dual mode, a kind of is the hot flow path injection mode that adopts common plastic rubber shaping commonly used, and another kind is to adopt the cold runner injection system.And in traditional rubber cold runner mould design, be to use sprue bush to connect between runner and the cavity plate, because sprue bush directly contacts cavity plate, and the temperature of cavity plate can reach when moulding about 180 degree, so the temperature of sprue bush is because the heat conduction also can form high temperature, thereby cause the sizing material in the sprue bush fully not cool off, vulcanizate might enter product, thereby influences the quality of rubber product.
The utility model content
The utility model purpose: in order to overcome the deficiencies in the prior art, a kind of cold runner rubber ejection shaping die that the utility model proposes reduces the sprue bush environment temperature, and its interior sizing material is fully cooled off, and improves the quality of rubber product.
Technical scheme: for solving the problems of the technologies described above, this mould comprises glue-feeder, thereunder be provided with runner plate, cooling unit, thermal insulation board and cavity plate successively, be connected by sprue bush between runner and the cavity plate, be provided with the recirculated cooling water road in the cooling unit and be used for sprue bush is cooled off, be provided with sealing ring and lower seal on the sprue bush.
Beneficial effect: compared with prior art, this mould cools off around the sprue bush by the recirculated cooling water road, effectively reduces the temperature of sizing material in it, has avoided vulcanizate to enter product, has improved the quality of rubber product; And, avoid producing drainage by sealing circulation waterway in that sealing ring and lower seal are set on the sprue bush, guaranteed its sealing.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in the figure, a kind of cold runner rubber ejection shaping die described in the utility model comprises glue-feeder 1, thereunder is provided with runner plate 2, cooling unit 3, thermal insulation board 4 and cavity plate 5 successively, is connected by sprue bush 7 between runner 6 and the cavity plate 5.
Because sprue bush 7 directly contacts with cavity plate 5, and the temperature of cavity plate 5 can reach when moulding about 180 degree, so sprue bush 7 is because the heat conduction also can form high temperature, for preventing that the too high vulcanizate that produces of sizing material Yin Wendu enters the product phenomenon in the sprue bush 7, being provided with the 8 pairs of sprue bush 7 in recirculated cooling water road in cooling unit 3 cools off, seal this recirculated cooling water road 8 also being provided with sealing ring 9 and lower seal 10 on the sprue bush 7, avoid producing drainage, guaranteed its sealing.
Simultaneously, the thermal insulation board 4 that adopts high-effect heat-barrier material to make intercepts the heat transmission between cavity plate and the runner plate, thereby realizes the effective control to the sizing material temperature.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
