Abstract
The utility model relates to a cylinder sealing ring injection mould, which comprises mold cores arranged at both sides of a beam and tightly connected with the beam, wherein both ends of the beam are hinged with a lift frame via rotating pins, the beam is in a cone structure and is fixedly matched with the conical surface of a lower template, the lower template and the beam are in gapless matching connection, and an upper template and the lower template are in structures without special runner plates, and without pour plugs or material cups. The utility model has the advantages of long service life, better sealing performance and better and uniform product density; and the mold cores fall into a lower die in die assembly along with the automatic positioning of the whole lift frame, so the defect that the mould is easily crushed by manual arrangement can be overcome, and the working efficiency is improved.
Description
Technical field
The utility model relates to the technology of die manufacturing field, relates in particular to a kind of column sealed circle injection molding.
Background technology
Similar injection molding is generally the filler mold pressing, and its product density difference and density unevenness are even, can influence the service life and the sealing property of product; Then need filler equally if adopt the material cup to annotate a pressure mode, core rod can not with middle template to lift the frame part hinged, product then can not rotate the demoulding, production efficiency is low.
The utility model content
At above defective, the purpose of this utility model provides a kind of its mould and adopts no dedicated stream guidance tape, do not have the plug of notes and expect cup structure, long service life, the preferable column sealed circle injection molding of sealing property, to solve many defectives of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of column sealed circle injection molding, comprise core rod, described core rod arrangement is arranged at the crossbeam both sides and closely is connected with crossbeam, described crossbeam two ends are by shipping and reselling on another market and to lift frame hinged, described crossbeam be cone structure and with lower bolster conical surface secure fit, described lower bolster and crossbeam are connected for no clearance-type, and cope match-plate pattern and lower bolster adopt no dedicated stream guidance tape, do not have the plug of notes and material cup structure.
The beneficial effect of column sealed circle injection molding described in the utility model is: mould adopts no dedicated stream guidance tape, do not have the plug of notes and material cup structure, long service life, sealing property are preferable, the product density better and even; Fall into counterdie with lifting the whole location automatically of frame during the core rod matched moulds, can overcome by hand and put into the shortcoming of easily damaging mould by pressure, improved operating efficiency.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the sectional structure chart of the described column sealed circle injection molding of the utility model embodiment;
Fig. 2 is the described column sealed circle injection molding part planar structure schematic diagram of the utility model embodiment.
Among the figure:
1, lifts frame; 2, lower bolster; 3, cope match-plate pattern; 4, core rod; 5, crossbeam; 6, guide pillar; 7, guide pin bushing; 8, ship and resell on another market.
The specific embodiment
Shown in Fig. 1-2, column sealed circle injection molding described in the utility model, comprise core rod 4, described core rod 4 is arranged between cope match-plate pattern 3 and the lower bolster 2, arrange behind its chamfered edge and be arranged at crossbeam 5 both sides and arrive die cavities with 5 tight connections of crossbeam so that runner can pass through core rod 4, this crossbeam 5 be cone structure and with lower bolster 2 conical surface secure fit, crossbeam 5 is led when matched moulds, smooth matched moulds and lower bolster 2 and crossbeam 5 are connected for no clearance-type, runner can guarantee that colloid does not overflow during by crossbeam 5; Described crossbeam 5 two ends are by shipping and reselling on another market 8 with to lift frame 1 hinged and be fixed on the release framework of vulcanizing press, lower bolster 2 and cope match-plate pattern 3 arranged outside have the guide pillar 6 of guide pin bushing 7, vulcanizing press core rod 4 when die sinking is ejected by integral body, rotating beam 5 is convenient to air gun and fast product is blown out again, core rod 4 is whole by inclined-plane, the quick matched moulds in guide pillar 6 location when matched moulds equally, rubber has greatly improved efficient by annotating mouth material feeding fast automatically.
Claims (3)
1. a column sealed circle injection molding comprises core rod (4), it is characterized in that: described core rod (4) is arranged and to be arranged at crossbeam (5) both sides and closely to be connected with crossbeam (5), and described crossbeam (5) two ends are by shipping and reselling on another market (8) and to lift frame (1) hinged.
2. column sealed circle injection molding according to claim 1 is characterized in that: described crossbeam (5) for cone structure and with lower bolster (2) conical surface secure fit.
