Abstract
A kind of improved-type mold of tunnel gate, including solid plate, moving platen, there is fixed die insert on solid plate, there is moving die insert on moving platen, there is the runner being connected to workpiece cavity on moving die insert, there is tunnel gate to be connected between runner and workpiece cavity, the tunnel gate into spherical in shape at glue, it is jagged between runner and tunnel gate.The improved-type mold of tunnel gate of the utility model, since tunnel gate is into spherical in shape at glue, it is jagged between runner and tunnel gate, it can make noresidue at product cast gate after demoulding, runner makes notch type, it the molding material bending of runner indentation, there can be disconnected during workpiece is ejected, preferably cut off runner and product.Have the advantages that noresidue, product appearance effect are good at tunnel gate after the demoulding of simple in structure, workpiece shaping.
Description
Technical field
The utility model is related to a kind of mold, especially a kind of improved-type mold of tunnel gate.
Background technology
Tunnel gate be it is very common a kind of into glue mode in injection mold, it is more next with requiring now product appearance
Stringenter, unreasonable tunnel gate is exactly to have residual on product, influences product appearance, concrete structure includes solid plate, dynamic model
Plate has fixed die insert on solid plate, has moving die insert on moving platen, there is the stream being connected to workpiece cavity on moving die insert
Road has tunnel gate to be connected between runner and workpiece cavity.There is residual at tunnel gate when workpiece demoulds after injection molding.
Invention content
The purpose of this utility model be to provide after a kind of simple in structure, workpiece shaping demoulding at tunnel gate noresidue,
The improved-type mold of the good tunnel gate of product appearance effect, overcome the deficiencies in the prior art.
The improved-type mold of tunnel gate of the utility model, including solid plate, moving platen, there is cover half edge on solid plate
Block has moving die insert on moving platen, has the runner being connected to workpiece cavity on moving die insert, have between runner and workpiece cavity
Tunnel gate is connected to, the tunnel gate into spherical in shape at glue, it is jagged between runner and tunnel gate.
The improved-type mold of tunnel gate of the utility model, since tunnel gate is into spherical in shape at glue, runner with it is latent
It is jagged between cast gate, noresidue at product cast gate, runner can be made to make notch type after demoulding, can be ejected in workpiece
The molding material bending of runner indentation, there disconnects in journey, preferably cuts off runner and product.With simple in structure, workpiece shaping is de-
After mould at tunnel gate the good advantage of noresidue, product appearance effect.
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 improved-type mold of tunnel gate of the utility model, including solid plate 4, moving platen 6, in solid plate
There is fixed die insert 5 on 4, there is moving die insert 7 on moving platen 6, there is the runner 1 being connected to workpiece cavity 3 on moving die insert 7, flows
There is tunnel gate 2 to be connected between road 1 and workpiece cavity 3, the tunnel gate 2 into spherical in shape at glue, runner 1 is poured with latent
Jagged 8 between mouth 2.
The improved-type mold of tunnel gate of the utility model, since tunnel gate 2 is into spherical in shape at glue, runner 1 with it is latent
Jagged 8 between volt cast gate 2, noresidue at product cast gate, runner 1 can be made to make notch type after demoulding, it can be in workpiece quilt
The molding material bending of runner indentation, there disconnects in ejection process, preferably cuts off runner and product.With simple in structure, workpiece
After shaping and demoulding at tunnel gate the good advantage of noresidue, product appearance effect.
