Abstract
A mould with high productivity for injection moulding is composed of base, ejection rods and their fixing plate, movable and static moulding plates and their bed plates with channel of cooling water, moulding cores with flow channel of cooling water, the inlet and outlet of cooling water, and a sealing plate of cooling water under said bed plate of movable moulding plate.
Description
One, technical field
The present invention relates to a kind of injection mold.
Two, background technology
At present, injection mold such as C45 (DZ47) miniature circuit breaker housing injection mold is provided with cooling system in dynamic and static template or dynamic and static die-cushion plate, because cooling effect is undesirable, unit interval depanning number of times is few, and production efficiency is not high; If increase unit interval depanning number of times, because cooling effect is undesirable, the mould temperature is too high during depanning, and injecting products easy deformation after contraction is excessive, and the percent defective height is lost more than gain.
Three, summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists, a kind of injection mold that designs the cooling water runner in core is provided, improve unit interval depanning number of times.
For achieving the above object, the solution that the present invention takes is: a kind of injection mold, it comprises mould pin, push rod and push rod fixed head, moving platen and dynamic model backing plate, core, quiet template and quiet die-cushion plate, cooling water inlet and coolant outlet, in dynamic model backing plate and quiet die-cushion plate, all have the cooling water channel that communicates with cooling water inlet and coolant outlet, the cooling water runner is set in each core, cooling water channel communicates with the cooling water runner, the dynamic model backing plate is placed dynamic model transition cooling water sealing plate down, places quiet mould transition cooling water sealing plate on the quiet die-cushion plate.Cooling water inlet and coolant outlet can be opened on dynamic model backing plate and quiet die-cushion plate, also can open on moving platen and quiet template, can also open on dynamic model transition cooling water sealing plate and quiet mould transition cooling water sealing plate.
Owing to designed dynamic model transition cooling water sealing plate and quiet mould transition cooling water sealing plate, cooling water channel can be communicated with the cooling water runner, reached and directly carry out cooling purpose in core, compared with dynamic and static template or dynamic and static die-cushion plate are cooled off, cooling effect greatly improves.Because the raising of cooling effect has improved unit interval depanning number of times, production efficiency improves widely.It is specially adapted to the injecting products of complicated core.
Four, description of drawings
Fig. 1 is the structural representation of present embodiment.
Fig. 2 is the dynamic model backing plate stereogram among Fig. 1.
Fig. 3 is the moving platen vertical view among Fig. 1.
Among the figure: 1, push rod fixed head, 2, the mould pin, 3, dynamic model transition cooling water sealing plate, 4, dynamic model backing plate, 5, core, 6, quiet template, 7, quiet die-cushion plate, 8, quiet mould transition cooling water sealing plate, 9, moving platen, 10, cooling water inlet, 11, cooling water inlet, 12, push rod, 13, cooling water channel, 14, the cooling water runner.
Five, the specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is remake description.Present embodiment is C45 miniature circuit breaker housing four impression injection mold tools.
Referring to Fig. 1-Fig. 3, a kind of injection mold, it comprises mould pin 2, push rod 12 and push rod fixed head 1, moving platen 9 and dynamic model backing plate 4, core 5, quiet template 6 and quiet die-cushion plate 7, cooling water inlet 10 and coolant outlet 11, in dynamic model backing plate 4 and quiet die-cushion plate 7, all have the cooling water channel 13 that communicates with cooling water inlet 10 and coolant outlet 11, in each core 5, cooling water runner 14 is set, cooling water channel 13 communicates with cooling water runner 14, the dynamic model backing plate is placed dynamic model transition cooling water sealing plate 3 for 4 times, places quiet mould transition cooling water sealing plate 8 on the quiet die-cushion plate 7.Cooling water inlet 10 and coolant outlet 11 are opened on dynamic model backing plate 4 and quiet die-cushion plate 7.
Referring to Fig. 2, two cooling water channels 13 that in dynamic model backing plate 4 and quiet die-cushion plate 7, all have two cooling water inlets 10 and coolant outlet 11 and communicate with cooling water inlet 10 and coolant outlet 11 separately.Many the cooling water channels 13 that in dynamic model backing plate 4 and quiet die-cushion plate 7, can have a plurality of cooling water inlets 10 and coolant outlet 11 and communicate with cooling water inlet 10 and coolant outlet 11 separately.
Referring to Fig. 2 and Fig. 3, its cooling work principle is summarized as follows: flow to the B place when cooling water first cooling water inlet 10 by dynamic model backing plate 4 (quiet die-cushion plate 7) flows into cooling water channel 13 from A, enter the cooling water runner 14 of first core 5 by the B1 place from B, flow through the C place from other end C1 and enter cooling water channel 13 again, enter the cooling water runner 14 of second core 5 again by the D1 place from D, flow through the E place from other end E1 and enter cooling water channel 13 again, flow to first coolant outlet 11 from F.Cooling is come in from second cooling water inlet 10, and is the same from second coolant outlet 11 cooling principle that comes out.Article one, cooling water channel 13, at least by and cool off two cores 5.
