Abstract
The invention discloses a hot runner system for injection moulding. The hot runner system comprises a flow distribution plate, an insert, a valve needle and a lever, wherein the cross section of the insert is circular; the flow distribution plate is provided with a runner; a mounting hole is formed in one surface of the flow distribution plate; the insert is arranged in the mounting hole; the runner of the flow distribution plate is communicated with an opening of the mounting hole; the mounting hole is connected with the other surface of the flow distribution plate through a valve needle hole; the diameter of the valve needle hole is less than that of the cross section of the insert; one end of the valve needle is connected with the lever, and the other end of the valve needle penetrates through the valve needle hole to be fixedly connected with the insert; the insert can be driven to slide in the mounting hole. The hot runner system for the injection moulding adopts a runner structure with an opening end and a semi-closed end; during working, the insert can be relatively tightly adhered to the bottom of the runner under the extrusion of heat flow, and the plastic overflow is prevented.
Description
Technical field
The present invention relates to the injection molding technology field, relate in particular to a kind of injection moulding TOP-TIP.
Background technology
Generally adopting at present injection mold in Injection Industry is HOT RUNNER INJECTION MOULD, mould comprises one for guiding and controls the TOP-TIP that the raw material hot-fluid enters die cavity, existing TOP-TIP as shown in Figure 1, comprise: flow distribution plate 101, be provided with the runner 102 of T shape in flow distribution plate 101, be equipped with in runner 102 and mobilizablely insert 103,103 one of blocking in 102 two outlets of runner that insert, make hot-fluid flow out from another outlet; Needle 104 1 ends are connected with lever 105, and the other end 103 is connected with inserting, and under lever 105 drives, needle 104 drags inserts 103 in the interior slip of runner 101, to realize opening and sealing of runner 101.
But in use, material easily occurs to leak with TOP-TIP in this injection moulding, because under hot-fluid impacts for a long time, to insert and can move toward an end of runner sealing, and then runner 102 103 is staggered with inserting, gap appears.And install the locking cushion block additional at the runner blind end and can not deal with problems, because the locking cushion block can interfere with lever, affect normal operating.
Summary of the invention
The technical problem to be solved in the present invention is how to solve existing injection moulding easily to produce the Lou problem of material with TOP-TIP.
For solving the problems of the technologies described above, the invention provides a kind of injection moulding TOP-TIP, comprising: flow distribution plate, mold insert, needle and lever, the cross section of described mold insert is circular, described flow distribution plate is provided with runner; The one side of described flow distribution plate is provided with installing hole, described mold insert be located at described installing hole in, and make the open communication of runner and the installing hole of flow distribution plate; Described installing hole is connected by the needle hole with the another side of described flow distribution plate, and the diameter in described needle hole is less than the diameter of section of described mold insert; One end of described needle is connected with described lever, and the other end is fixedly connected with described mold insert through described needle hole, and can drive described mold insert and slide in described installing hole.
Preferably, the axle center of the axle center of needle and mold insert is overlapping.
This injection moulding adopts the semi-enclosed flow passage structure of an end opening other end with TOP-TIP, and during work, mold insert only can more be adjacent to the bottom of runner under the hot-fluid extruding, and not there will be excessive glue.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing TOP-TIP.
Fig. 2 is injection moulding of the present invention hot runner system structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for the present invention is described, but are not used for limiting the scope of the invention.
Injection moulding TOP-TIP as shown in Figure 2 comprises: flow distribution plate 1, mold insert 2, needle 3 and lever 4, and the cross section of mold insert 2 is circular, flow distribution plate 1 is provided with runner 5; The one side of flow distribution plate 1 is provided with installing hole 6, mold insert 2 be located at installing hole 6 in, make the open communication of runner 5 with the installing hole 6 of flow distribution plate 1; Installing hole 6 is connected by needle hole 7 with the another side of flow distribution plate 1, and the diameter in needle hole 7 is less than the diameter of section of mold insert 2; One end of needle 3 is connected with lever 4, and the other end is fixedly connected with mold insert 2 through needle hole 7, and can drive mold insert 2 in the interior slip of installing hole 6, and the axle center of the axle center of needle 3 and mold insert 2 is overlapping.When TOP-TIP needs material feeding, rotating lever 4, make mold insert 2 move to installing hole 6 bottoms of the leftmost side, like this runner 5 just can with the open communication of installing hole 6, and can material feeding.When needs stop material feeding, rotate backward lever 4, mold insert 2 is moved to installing hole 6 right sides, make mold insert 2 block runner 5, stop material feeding.
This injection moulding adopts the semi-enclosed flow passage structure of an end opening other end with TOP-TIP, and during work, mold insert only can more be adjacent to the bottom of runner under the hot-fluid extruding, and not there will be excessive glue.
Above embodiment is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
Claims (2)
1. an injection moulding TOP-TIP, is characterized in that, comprising: flow distribution plate, mold insert, needle and lever, and the cross section of described mold insert is circular, described flow distribution plate is provided with runner; The one side of described flow distribution plate is provided with installing hole, and described mold insert is located in described installing hole, and makes the open communication of runner and the installing hole of flow distribution plate; Described installing hole is connected by the needle hole with the another side of described flow distribution plate, and the diameter in described needle hole is less than the diameter of section of described mold insert; One end of described needle is connected with described lever, and the other end is fixedly connected with described mold insert through described needle hole, and can drive described mold insert and slide in described installing hole.
