Abstract
The utility model provides one kind and efficiently separates cast gate waste material injection mold, and the program includes the model cavity being arranged on mold, sprue channel open and injection channel；Sprue channel open connects model cavity with injection channel；Sprue channel open and the interface bore of injection channel are more than the interface bore of sprue channel open and model cavity；Sprue channel open is taper.This programme is designed using up big and down small sprue channel open, it is used under the conditions of load bears identical pulling force, the principle that most weakness is broken at first, cast gate waste material can be made to be efficiently separated with injection-molded item and related extraction, the process for saving subsequent artefacts' deburring, improve the production efficiency of injection-molded item.
Description
Technical field
The utility model relates to static discontinuous injection mold, especially one kind efficiently separates cast gate waste material injection mould
Tool.
Background technology
During carrying out rubber, plastic products are manufactured, because the design of mold injection material feeder channel is unreasonable, lead
Cause passage portion clout（Main finger and injection-molded item connected component, are referred to as " cast gate waste material "）Remain on injection-molded item, need artificial
It is processed again to reject the portion of residual material, because now injection-molded item has freezed off shaping, this measure will cause injection-molded item
Surface is not clean and will increase cost of labor input.
Utility model content
The purpose of this utility model, aiming at the deficiency present in prior art, and one kind is provided and efficiently separates cast gate
Waste material injection mold, the program are designed using up big and down small sprue channel open, are used under the conditions of load bears identical pulling force, most weak
Locate the principle being broken at first, cast gate waste material can be made and injection-molded item efficiently separates and related extraction, subsequent artefacts are saved and repair
The process on side, improve the production efficiency of injection-molded item.
This programme is achieved by the following technical measures：
One kind efficiently separates cast gate waste material injection mold, includes the model cavity being arranged on mold, sprue channel open and note
Mould passage；Sprue channel open connects model cavity with injection channel；Sprue channel open and the interface bore of injection channel are more than sprue channel open and mould
The interface bore of die cavity；Sprue channel open is taper.
As the preferred of this programme：The opening size that injection channel is located at outside model cavity is more than injection channel and sprue channel open
The opening size of junction.
As the preferred of this programme：Region between injection channel and sprue channel open is the taper shunk towards model cavity direction.
As the preferred of this programme：Connecting portion between model cavity and sprue channel open is provided with step.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due in this scenario using up big and down small
Sprue channel open design, be used under the conditions of load bears identical pulling force, the principle that most weakness is broken at first, cast gate waste material can be made
Efficiently separated with injection-molded item and related extraction, the process for saving subsequent artefacts' deburring, the production for improving injection-molded item are imitated
Rate.Practice have shown that the injection mold that " running channel " shape is designed using the principle carries out injection-molded item production, note can be effectively eliminated
Mould the cast gate waste material on product.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at sprue channel open.
In figure, 1 is mold, and 2 be model cavity, and 3 be injection channel, and 4 be sprue channel open.
Embodiment
For the technical characterstic for illustrating this programme can be understood, below by an embodiment, and its accompanying drawing is combined, it is right
This programme is illustrated.
By accompanying drawing as can be seen that this programme includes the model cavity being arranged on mold, sprue channel open and injection channel；
Sprue channel open connects model cavity with injection channel；Sprue channel open and the interface bore of injection channel are more than connecing for sprue channel open and model cavity
Mouth bore；Sprue channel open is taper.The opening size that injection channel is located at outside model cavity is connected more than injection channel with sprue channel open
The opening size at place.Region between injection channel and sprue channel open is the taper shunk towards model cavity direction.Model cavity and running channel
Connecting portion between mouthful is provided with step.
After injection step starts, from the plastics of injection hole injection thawing, model cavity is entered by sprue channel open, waits plastics
After cooled and solidified shaping, mould is opened, whole injection-molded item is taken out and connects superincumbent overlap material, then roll over overlap material
Disconnected, because sprue channel open is arranged to up big and down small structure, therefore the overlap material close to injection-molded item one end is first broken, so as to play
The effect that whole waste material is all removed from injection-molded item, given up without manually rejecting the remnants being connected on injection-molded item again
Material.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
