Abstract
The utility model discloses a main injection nozzle of hot runner system, which comprises a main injection nozzle body and an ingate sleeve detachably mounted on the main injection nozzle body; when the main injection nozzle is not matched with the injection tube of an injection molding machine, only the ingate sleeve of the main injection nozzle is replaced, and the whole main injection nozzle is not needed to be replaced; so the time is saved, and the production cost is reduced.
Description
Technical field
The utility model relates to TOP-TIP, especially relates to the main injection nozzle structure of TOP-TIP.
Background technology
The injection mold that generally adopts in the injection moulding industry at present is the HOT RUNNER INJECTION MOULD tool, and it generally comprises injection machine, and with the hot runner mould that injection machine is connected by main nozzle, hot runner mould is connected with the product pattern pattern is advanced in the injection raw material injection moulding to carry out injection molding operation.The HOT RUNNER INJECTION MOULD tool remains on molten condition with injection raw material, do not have to solidify caking, the unimpeded injection molding operation that carries out.It has with respect to traditional cold runner mould and economizes in raw materials, and improves product quality, improves operating efficiency, simplifies the plurality of advantages of production process.Certainly, this HOT RUNNER INJECTION MOULD tool part that also unavoidably comes with some shortcomings, such as, the main nozzle that is connected with injection machine, the cast gate and the main nozzle main body of existing main injection nozzle structure itself and injection machine connecting portion are formed in one, when the concave surface radian at main nozzle cast gate place or main nozzle cast gate place charging aperture diameter can not be complementary with the radian of the injection molding tube end face of injection machine or injection molding tube discharging opening diameter, then need to change whole main nozzle, bring very big inconvenience to operation, and owing to be that global facility is changed, then need to prepare the main nozzle of each model, when main nozzle wearing and tearing or damage can not the time spent, must be whole discarded, increased a lot of production costs; And need bear certain pressure when being connected with injection machine owing to main nozzle, then require main nozzle and injection machine connecting portion material hardness height, because main nozzle gate part and main body are formed in one, the material hardness that adopts or identical for improving the material hardness processing method has increased main nozzle manufacturing cost virtually again.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of gate part and can dismantle separately, the main nozzle of replacing.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is a kind of main nozzle of TOP-TIP, it comprises that one has the main nozzle body that connects runner, it is characterized in that also comprising that one has the sprue bush that connects runner, described sprue bush one end face is an arc-shaped concave, its other end is installed in described main nozzle body one end removably, makes described main nozzle runner be connected perforation with described sprue bush runner.
Described main nozzle body and described sprue bush link together by screw thread is detachable.
The sprue bush of the utility model master nozzle itself and injection machine contact jaw is detachable, when the runner of main nozzle gate end flow diameter or gate end radian and injection machine injection molding tube or end face radian do not match, can only dismantle submarine gate cover changes, avoid the trouble of main nozzle integral replacing, saved the activity duration; When produce preparing, the sprue bush that also only needs to prepare the different model that can be used for changing gets final product, and has saved production apparatus cost of investment; For Mould Machining enterprise, only sprue bush adopts high hardness material or carries out the high rigidity processing technology and handle, and main nozzle body can adopt the low slightly material of hardness, has reduced manufacturing cost.

The specific embodiment
For the better the utility model of setting forth, now to lift a preferred embodiment and be specifically described as followsly in conjunction with graphic, it comprises main nozzle body 1, the sprue bush 2 of main nozzle; With reference to figure 2:
Sprue bush 2, it has consistent passage flow duct 21, and itself and injection machine contact jaw end face are arc-shaped concave 22, and runner 21 1 end openings are positioned at this arc-shaped concave 22 places; Form screw thread on sprue bush 2 other end periphery walls, the shape degree of depth of the recess 12 of its moulding threaded perisporium shape length and main nozzle body 11 is coincide, the other end opening of runner 11 is positioned at the end of the threaded end of sprue bush 2 moulding, and this opening internal diameter equals the opening internal diameter that main nozzle body 1 runner 11 is positioned at recess 12 places; Sprue bush 2 is installed in recess 12 places of main nozzle body 1 by the screw thread screw lock, its contact jaw face mechanical seal, and runner 11 is connected perforation with runner 21.
The utility model also can adopt another embodiment (not shown), it is with above-mentioned embodiment difference: main nozzle body 1 forms screw thread near cast gate one end periphery wall, sprue bush 2 forms screwed recess on the perisporium with main nozzle body 1 link, and sprue bush 2 is installed on the main nozzle body 1 by the screw thread screw lock.
Certainly, main nozzle body 1 and sprue bush 2 can be not yet by being threaded, but by screw, pin etc. are detachable to link together, contacting end face and also can adopting other modes to seal of main nozzle body 1 and sprue bush 2 avoids the injection moulding fused raw material to enter contact end face slit.
Claims (2)
1. the main nozzle of a TOP-TIP, it comprises that one has the main nozzle body that connects runner, it is characterized in that also comprising that one has the sprue bush that connects runner, described sprue bush one end face is an arc-shaped concave, its other end is installed in described main nozzle body one end removably, makes described main nozzle runner be connected perforation with described sprue bush runner.
2. the main nozzle of TOP-TIP according to claim 1, it is characterized in that described main nozzle body and described sprue bush by threaded connection detachable combine.
