Description
Technical field
The utility model relates to a kind of injection moulding field, particularly a kind of hot runner molding machine and integral type injection heat mouth.
Background technology
At present, hot runner mould is widely used in each big industry.Shown in Fig. 1 (a) and Fig. 1 (b), the conventional hot flow path mouth of hot runner mould, formed with sharp-tongued 20 by cast gate department 10, the gap 30 that hot mouth portion's cast gate dead 10 of common die and sharp-tongued 20 designs have 0.5mm-1mm, mainly acting as of this gap 30 prevents the too fast cold glue that causes of melten gel cooling, also has cushioning effect.Sharp-tongued 10 outer one deck fusion sizing materials that are wrapped in for a long time, in long high temperature, the easy charing of this sizing material, interior voltage rise height after the charing, the charing sizing material can be regurgitated when interior pressure acquires a certain degree.This phenomenon product in dark product injection moulding embodies not too obvious, but is presented as product surface jaundice, mashed glue etc. when producing transparent material, causes the product appearance defective; Simultaneously, sharp-tongued 20 with cast gate department 10 between owing to use repeatedly contact and occur wearing and tearing, make accessory damage easily.
The utility model content
Main purpose of the present utility model is for providing a kind of hot runner molding machine that improves injection defect and the integral type injection heat mouth of enhancing productivity and comprise integral type injection heat mouth.
The utility model proposes a kind of integral type injection heat mouth, comprise sharp-tongued and cast gate department, described sharp-tongued one-body molded with cast gate department.
Preferably, describedly sharp-tonguedly be provided with a runner at its axis direction.
Preferably, inwardly shrink the lower end of described runner.
Preferably, the lower end of described cast gate department is the filling mouth that cooperates with the core rod mouth.
Preferably, the outer surface of described cast gate department upper end is provided with external screw thread.
The utility model also proposes a kind of hot runner molding machine, comprises nozzle cage, needle and integral type injection heat mouth, and described integral type injection heat mouth comprises sharp-tongued and cast gate department, and is described sharp-tongued one-body molded with cast gate department.
Preferably, described needle is inserted in the described runner, and described runner lower end cooperates with described needle lower end.
Preferably, described integral type injection heat mouth is connected with described nozzle cage lower end, the external screw thread of cast gate department outer surface upper end and the screw-internal thread fit of described nozzle cage lower end.
Integral type injection heat mouth of the present utility model does not have cast gate department and sharp-tongued fit clearance, has solved in use because open defects such as the mashed glue of the product that the anti-glue of sizing material the gap causes, jaundice have significantly promoted yield of products from root; Simultaneously, also solved between sharp-tongued and the cast gate department because the problem that accessory damages appears in wearing and tearing, in the service life of having improved accessory, reduced the cost of production equipment accessory; Failure problems has been lacked in the production, makes production process more smooth and easy, effectively raises production efficiency.
