Abstract
The utility model discloses an injection mold of tubular parts, which belongs to a mold and has the advantages of simple and compact structure and convenience and quickness in demolding. The injection mold comprises a sprue bush, an upper mold, a lower mold and a mold core, wherein the sprue bush (5) is fixed on a panel (20), and the upper mold (2), which is fixed on the back surface of an upper mold plate (19), is arranged below the sprue bush; the lower mold (14), which is fixed on the surface of a lower mold plate (18), is arranged below the upper mold, and the sprue bush (5) is communicated with a mold cavity formed by the upper mold (2) and the lower mold (14) through a flow passage; springs (12) are fixed between the lower mold plate (18) and a thimble plate (11) below the lower mold plate (18), and a thimble (17) fixed on the thimble plate (11) is inserted into a thimble hole in the lower mold plate (18); the mold core (3) in the mold cavity is connected with a piston rod of an oil cylinder through a pull block (6). The injection mold disclosed by the utility model has the advantages of short mold opening ejection distance and high demolding efficiency, and is used for manufacturing the tubular parts.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of injection mold.
Background technology
As everyone knows, in auto parts and components, having many is tubulose class plastic parts, conventionally adopts injection moulding mode to process.Yet, at present large for the general more complicated of mould structure, the die size of processing plastic tubulose class auto parts and components, not only waste mold materials, and must adopt the larger injection-moulding device in molar space; In addition, traditional tubulose class part injection mold also exists die sinking to eject many defects such as distance, demoulding efficiency is low, the demoulding is difficult.
Summary of the invention
For the above-mentioned defect existing in prior art, the utility model aim to provide a kind of simple and compact for structure, be convenient in demoulding tubular member injection mold efficiently.
To achieve these goals, the utility model by the following technical solutions: it comprises sprue bush, upper die and lower die and core rod; Sprue bush and guide pillar are fixed on panel, and this back side of panel is fixed with stripper plate, and the below of this stripper plate is the cope match-plate pattern coordinating with guide pillar, and the patrix that is provided with upper cavity is fixed on the back side of this cope match-plate pattern, and the runner of this patrix is communicated with described upper cavity with sprue bush; The below of cope match-plate pattern is lower bolster, the counterdie that is provided with lower mode cavity is fixed on the surface of this lower bolster, core rod is located in the die cavity being combined to form by described lower mode cavity and upper cavity, this core rod is fixed on pulling block through the part plate of scraping being fixed on base, the oil cylinder being fixed on base is connected with this pulling block by piston rod, and base is fixed on lower bolster; The below of this lower bolster is ejector retainner plate, and the thimble being pressed on this ejector retainner plate by backing plate coordinates with the centre hole being located on lower bolster; Between lower bolster and ejector retainner plate, there is spring.
Compared with the prior art, the utility model, owing to having adopted technique scheme, is provided with thimble below cope match-plate pattern, even if therefore there is set plastic in runner, the plastics that also can cope match-plate pattern jack-up be made to be set in runner by thimble are thoroughly separated with workpiece, thereby guarantee product quality; In addition, because thimble is shorter by the distance of cope match-plate pattern jack-up, therefore improved demoulding efficiency.Moreover, owing to having adopted, scrape part plate, when core rod is extracted out from die cavity when cylinder piston rod retraction, can guarantee that workpiece and core rod are separated and the demoulding is very convenient quick smoothly.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
In figure: stripper plate 1 patrix 2 core rods 3 are scraped part plate 4 sprue bush 5 pulling block 6 guide pillar 7 oil cylinder 8 oil cylinder seat 9 base 10 ejector retainner plate 11 spring 12 push rod 13 counterdie 14 base plate 15 backing plate 16 thimble 17 lower bolster 18 cope match-plate pattern 19 panels 20
the specific embodiment:below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figure 1: sprue bush 5 is fixed on panel 20, and stripper plate 1 is fixed on this back side of panel, the guide pillar 7 being fixed on panel 20 coordinates with the cope match-plate pattern 19 of its below through this stripper plate; The patrix 2 that is provided with upper cavity is fixed on the back side of this cope match-plate pattern, and the runner (not shown) being located on patrix 2 is communicated with described upper cavity with sprue bush 5.The below of cope match-plate pattern 19 is lower bolsters 18, and the counterdie 14 that is provided with lower mode cavity is fixed on the surface of this lower bolster, upper cavity
withthis lower mode cavity is combined to form die cavity; The core rod 3 being located in this die cavity is fixed on pulling block 6 through the part plate 4 of scraping being fixed on base 10, and the oil cylinder 8 being fixed on base 10 by oil cylinder seat 9 is connected with this pulling block by piston rod, and base 10 is fixed on lower bolster 18.The below of this lower bolster is ejector retainner plate 11, by backing plate 16, is pressed on (not shown) in the centre hole that thimble on this ejector retainner plate 17 inserts lower bolsters 18; Between lower bolster 18 and ejector retainner plate 11, have spring 12, the two ends of this spring are separately fixed on lower bolster 18 and ejector retainner plate 11.
During work, the utility model is fixed on injection-moulding device by base plate 15.During injection moulding, from sprue bush 5, the runner (not shown) through being located at cope match-plate pattern 19 and patrix 2 enters die cavity and forms workpiece plastics; During die sinking, first stripper plate 1 and panel 20 are lifted, the plastics that make to be set in runner are separated with workpiece; Then the push rod 13 of injection-moulding device is by backing plate 16 and thimble 17 by cope match-plate pattern 19 jack-up, and patrix 2 is separated with counterdie, die cavity is opened; Meanwhile, the piston rod of oil cylinder 8 retreats, and until core rod 3, after extracting out die cavity, can take out workpiece.
