Abstract
The invention discloses a kind of injection moulding process of hole straight forming, comprise the following steps：The first step, nylon material is melted；Second step, mandrel (4) is inserted in cover half (6), and the material of thawing is injected in sprue bush (5), and plastic melt reaches die cavity by sprue；3rd step, after cooling, promote flat board (14), flat board (14) drives head part bar (1), anti-push rod (9), sprue puller (13), anti- push rod (9) separation cover half (6) and dynamic model (7), head part bar (1) releases the half-finished parts after cooling, and sprue puller (13) releases remaining plastics, completes injection.The present invention has simplified manufacturing procedure, is that can obtain certified products by simple reconditioning.Improve product first-time qualification rate.
Description
Technical field
The invention belongs to die forming field, it is related to a kind of injection moulding process of hole straight forming.
Background technology
Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches.Refer specifically to the material of heated thawing injecting die cavity by high pressure, after cooling and solidifying, obtain formed products.
Existing injection mold is mainly made up of ejector beam, insert, sprue bush, cover half, dynamic model, anti-push rod, sprue puller, when being specifically formed, first by nylon material heating and melting, then the material of thawing is injected in sprue bush, plastic melt reaches die cavity by sprue, flat board is moved through supercooling pusher, flat board drives head part bar, anti-push rod and sprue puller, anti-push rod separation cover half and dynamic model.Head part bar releases the half-finished parts after cooling.Sprue puller releases remaining plastics.Half-finished parts need to obtain fabricated part after drilling.
The content of the invention
The purpose of the present invention：To improve processing efficiency, manufacturing procedure is simplified, shortens process time.Upgrading is optimized to existing injection moulding process, one-shot forming is reached, drilling operating is needed not move through and can obtain fabricated part.
Technical scheme：Comprise the following steps：
The first step, nylon material is melted；
Second step, mandrel (4) is inserted in cover half (6), and the material of thawing is injected in sprue bush (5), and plastic melt reaches die cavity by sprue；
3rd step, after cooling, promote flat board (14), flat board (14) drives head part bar (1), anti-push rod (9), sprue puller (13), anti- push rod (9) separation cover half (6) and dynamic model (7), head part bar (1) releases the half-finished parts after cooling, and sprue puller (13) releases remaining plastics, completes injection.
Advantages of the present invention：Manufacturing procedure has been simplified, has been that can obtain certified products by simple reconditioning.Improve product first-time qualification rate.
Brief description of the drawings：
Fig. 1 is the structural representation of injection mold of the present invention；
Wherein, 1 head part bar；2 pilot pins；3 inserts；4 mandrels；5 sprue bush；6 cover half；7 dynamic models；8 moving platens；9 anti-push rods；10 flat boards；11 legs；12 backing plates；13 sprue pullers；14 flat boards
Embodiment：
The present invention is described in further detail below by with reference to the drawings and specific embodiments.
A kind of nylon part injection mould of the present invention is to be successfully applied to the production process of nylon part.
4 mandrels are inserted in 6 cover half first, injection mould cover half constitutes die cavity with dynamic model closure.This part material is nylon 1010, and its fusing point is 188-190 DEG C.By Nylon-1010 heating and melting, material after thawing is injected in 1 sprue bush, plastic melt reaches die cavity by sprue, the flat boards of № 14 are moved through supercooling pusher, the flat boards of № 14 drive 1 head part bar, 9 anti-push rods and 13 sprue pullers, and 9 anti-push rods separate 6 cover half and 7 dynamic models.1 head part bar releases the part after cooling.13 sprue pullers release remaining plastics.Spring resets 6 cover half and 7 dynamic models after part takes out, and continues to produce.The part of taking-up by deburring processing it is to be tested it is qualified after deliver assembling.
