Abstract
The utility model discloses a hot runner injection mould with a corner insert, which comprises a flow distribution plate and a corner insert. The flow distribution plate is equipped with a flow passage hole and the corner insert is equipped with an arc-shaped flow passage hole. The corner insert is fixed in the flow distribution plate and arranged at the corner of the flow passage hole. The arc-shaped flow passage hole of the corner insert communicates with the flow passage hole of the flow distribution plate and accesses the corner thereof. The arc-shaped flow passage hole of the corner insert has a large-angle circular arc, thereby eliminating sharp corners or dead angles of the flow passage hole and avoiding the retention of plastic residues at the corner thereof. The structure of the utility model completely avoids the possibility of plastic yellowing and the yellowing and blackening of injection products.
Description
Technical field
The utility model relates to HOT RUNNER INJECTION MOULD tool technical field, especially relates to a kind of HOT RUNNER INJECTION MOULD tool with the corner mold insert.
Background technology
In the prior art, be provided with the runner hole in the HOT RUNNER INJECTION MOULD tool, shown in Figure 1, the runner hole forming is in flow distribution plate 1, and the HOT RUNNER INJECTION MOULD tool is carried plastic cement stream by runner hole 2.Yet there is corner in the runner hole 2, because the restriction of processing technology, the corner in runner hole 2 is 90 degree, the corner in runner hole 2 is sharp-pointed wedge angle, the corner in runner hole 2 is the dead angles in the runner hole 2, and the plastics in the hot flow path remain in the corner in runner hole 2 easily, and it can make the surface jaundice blackout of injecting products, therefore the quality of serious injecting products is necessary to be improved.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model provides a kind of HOT RUNNER INJECTION MOULD tool with the corner mold insert, and it avoids plastics to remain in the corner in runner hole.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of HOT RUNNER INJECTION MOULD tool with the corner mold insert, comprise flow distribution plate and corner mold insert, be provided with the runner hole in the flow distribution plate, be provided with arc runner hole in the corner mold insert, the corner mold insert is fixed in the flow distribution plate, and the corner mold insert is arranged at the corner in runner hole, and the arc runner hole of corner mold insert is communicated with the runner hole of flow distribution plate.
The corner in described arc runner hole has circular arc inside lock and the outer corner of circular arc.
The runner hole of described arc runner hole and flow distribution plate is tangent.
Described corner mold insert comprises the first corner mold insert and the second corner mold insert, the first corner mold insert and the second corner mold insert offer arc runner hole respectively half, form described arc runner hole in half arc runner hole of the first corner mold insert and second corner mold insert splicing back, the first corner mold insert and half arc runner hole of the second corner mold insert.
The straight channel hole is extended in the one or both ends in described arc runner hole.
After adopting said structure, the utility model is compared the advantage that is had with prior art: in the utility model, corner in the runner hole of the arc runner hole access flow distribution plate of corner mold insert, arc runner hole in the corner mold insert has bigger arc chord angle, has eliminated the wedge angle in the runner hole, does not have the dead angle to exist, the space that does not have plastics to retain, avoid plastics to remain in the corner in runner hole, avoided the possibility of plastics jaundice on the structure fully, avoid the product jaundice blackout of injection moulding.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the HOT RUNNER INJECTION MOULD tool of prior art.
Fig. 2 is the structural representation of HOT RUNNER INJECTION MOULD tool of the present utility model.
Fig. 3 is the decomposing schematic representation of corner mold insert of the present utility model.
Among the figure: 1, flow distribution plate 2, runner hole 3, arc runner hole 4, the first corner mold insert 5, the second corner mold insert.
The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see Fig. 2 and shown in Figure 3: a kind of HOT RUNNER INJECTION MOULD tool with the corner mold insert, comprise flow distribution plate 1 and corner mold insert, be provided with runner hole 2 in the flow distribution plate 1, be provided with arc runner hole 3 in the corner mold insert, the corner mold insert is fixed in the flow distribution plate 1, and the corner mold insert is arranged at the corner in runner hole 2, the runner hole 2 of the arc runner hole 3 connection flow distribution plates 1 of corner mold insert.
In the utility model, corner in the runner hole 2 of the arc runner hole 3 access flow distribution plates 1 of corner mold insert, arc runner hole 3 in the corner mold insert has bigger arc chord angle, eliminated the wedge angle in the runner hole 2, do not have the dead angle to exist, the space that does not have plastics to retain avoids plastics to remain in the corner in runner hole 2, avoid the possibility of plastics jaundice on the structure fully, avoided the product jaundice blackout of injection moulding.
The corner in arc runner hole 3 has circular arc inside lock and the outer corner of circular arc.
The straight channel hole is extended in the one or both ends in arc runner hole 3, and the runner hole 2 of straight channel hole and flow distribution plate 1 joins.
Arc runner hole 3 is tangent with the runner hole 2 of flow distribution plate 1.
The corner mold insert comprises the first corner mold insert 4 and the second corner mold insert 5, the first corner mold insert 4 and the second corner mold insert 5 offer arc runner hole respectively half, form described arc runner hole 3 in half arc runner hole of the first corner mold insert 4 and the second corner mold insert 5 splicing back, the first corner mold insert 4 and half arc runner hole of the second corner mold insert 5.
The design of the first corner mold insert 4 and the second corner mold insert 5 makes that the processing in arc runner hole 3 is more simple and convenient, reduces difficulty of processing.
Flow distribution plate 1 and runner hole 2 are widely-used at present, and other structure and principle are same as the prior art, repeat no more here.
