Abstract
The mold automatically cut off in the cast gate delayed ejection mould of the utility model, including solid plate and moving platen, solid plate and moving platen form workpiece cavity when molding, it is connected with workpiece cavity and is connected with side gate, runner, the mandril lower end of ejection workpiece is withstood on the needle plate of face, it further include the runner mandril for ejecting runner, the lower end of the runner mandril is withstood on delay mandril, delay mandril is located at the endoporus of face needle plate, there is step on delay mandril, runner pull rod is equipped in moving platen, the upper end of runner pull rod is stretched at runner, the lower end of runner pull rod acts against on the fixed block being fixedly connected with moving platen.This mold detaches workpiece and runner in demoulding, time saving and energy saving without manually being cut after demoulding, improves work efficiency, reduces labor intensity, simple in structure.
Description
Technical field
The utility model is related to a kind of mold, the mold that is automatically cut off in especially a kind of cast gate delayed ejection mould.
Background technology
Existing side-gate mold includes solid plate and moving platen, and solid plate and moving platen form workpiece cavity when molding,
It is connected with workpiece cavity and is connected with side gate, runner, the mandril lower end for ejecting workpiece is withstood on the needle plate of face, further includes ejection runner
Runner mandril, runner mandril upper end extend at runner, and runner mandril lower end acts against on the needle plate of face.After injection molding, moving platen moves down
When, face needle plate can move up demoulding, while mandril being pushed to eject workpiece, while runner mandril ejects runner, molding workpiece and stream
Road depanning simultaneously, workpiece is connected with runner, needs manually to cut, time-consuming and laborious.
Invention content
Workpiece is first ejected when the purpose of this utility model is to provide one kind simple in structure, demoulding, runner delay is ejected,
So that workpiece and runner is automatically separated in demoulding, without demoulding after manually cutting, cast gate that is time saving and energy saving, improving working efficiency prolong
The mold automatically cut off in ejection mould late, overcome the deficiencies in the prior art.
The mold automatically cut off in the cast gate delayed ejection mould of the utility model, including solid plate and moving platen, solid plate
Workpiece cavity is formed when being molded with moving platen, is connected with workpiece cavity and is connected with side gate, runner, ejects the mandril lower end top of workpiece
Further include the runner mandril for ejecting runner on the needle plate of face, the lower end of the runner mandril is withstood on delay mandril, delay top
Bar is located at the endoporus of face needle plate, has step on the mandril that is delayed, runner pull rod is equipped in moving platen, the upper end of runner pull rod is stretched into
At runner, the lower end of runner pull rod acts against on the fixed block being fixedly connected with moving platen.
The mold automatically cut off in the cast gate delayed ejection mould of the utility model, when demoulding, mandril is first acted with face needle plate,
Molding workpiece is ejected, while runner pull rod holds runner, since runner is not ejected at this time, workpiece can divide with runner
From.The mandril that is delayed acts later, and runner mandril is pushed to eject runner.Workpiece and runner are detached in demoulding, it is time saving and energy saving, it carries
High working efficiency, reduces labor intensity, simple in structure.
Description of the drawings
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Specific implementation mode
As shown in Figure 1：The mold automatically cut off in the cast gate delayed ejection mould of the utility model, including solid plate 3 and dynamic
Workpiece cavity 5 is formed when template 10, solid plate 3 and moving platen 10 mold, and is connected with workpiece cavity 5 and is connected with side gate 6, runner 4.
7 lower end of mandril of ejection workpiece withstands on face needle plate 12 and is relatively fixed clamping by 11 knead dough needle plate 12 of ejector retainner plate.It further include top
Go out the runner mandril 8 of runner 4.The lower end of runner mandril 8 is withstood on delay mandril 13, and delay mandril 13 is located at the interior of face needle plate 12
Hole 2, be delayed mandril 13 on have step 1.Runner pull rod 9 is equipped in moving platen 10, the upper end of runner pull rod 9 is stretched at runner 4,
The lower end of runner pull rod 9 acts against on the fixed block 16 being fixedly connected with moving platen 10.
The mold automatically cut off in the cast gate delayed ejection mould of the utility model, when demoulding, mandril 7 first with face needle plate 12,
The action of ejector retainner plate 11 moves up, and molding workpiece in workpiece cavity 5 is ejected, while runner pull rod 9 holds runner 4, since runner 4 does not have
It is ejected, workpiece is made to be detached in demoulding with runner 4.The mandril 13 that is delayed acts later, i.e., face needle plate 12 prolongs after moving up H distances
When mandril 13 act, push runner mandril 8 to move up ejection runner 4.Workpiece and runner are detached in demoulding, it is time saving and energy saving, it carries
High working efficiency, reduces labor intensity, simple in structure.
