Abstract
The utility model discloses an injection mold capable of automatically cutting off waste materials, comprising a mold holder and a mold core arranged on the mold holder, wherein a pouring slot of the mold holder, corresponding to the mold core, is provided with a material cutting device; a driving device capable of driving the material cutting device to carry out material cutting is arranged behind the material cutting device. The injection mold has simple structure, and is provided with the material cutting device and the driving device at the pouring port, thus being capable of automatically cutting off stub bars in injection molding of products, leading molded products not to have pouring gate stub bars, reducing the procedures of post processing, improving production efficiency, having high automation level and small labor intensity, guaranteeing the product quality while saving a great amount of manpower and material resources, and further being beneficial to the development of enterprises.
Description
Technical field
The utility model relates to mould, particularly a kind of injection mold of automatic excision waste material.
Background technology
Present decorative product or consumption electronic products, major part will rely on mould molding; Especially, along with the development of hyundai electronics industry, product shell miscellaneous all needs mould molding, and the effect of mould also becomes more important, and simultaneously, the optimal design of mould and the improvement of related process also become the higher target that die industry is pursued.
During the moulding of existing injecting products is produced, generally all have the running channel stub bar through the product behind the mould molding, the moulding product that the plastics that this running channel stub bar remains in the fusion in the running channel during for die sinking are ined succession in the mold cavity form, this running channel stub bar generally needs through back procedure for processing removal, the staff places this product that has the running channel stub bar on the tool, through operating this tool to remove the running channel stub bar, after the running channel stub bar is removed, generally can remove the edge and form burr at this, the staff also need repair to remove burr, after removing burr, product is again through inspecting the back packing.So the procedure for processing operation is various behind the product, both needs more manpower, need have again specially for removing the tool that the running channel stub bar designs, and tool damages the phenomenon of product when also regular meeting appears at stub bar.
In view of this, be necessary to provide a kind of equipment, to overcome in the prior art for needing problems such as the various and labour intensity of secondary operations processing procedure operation is big behind the injection mold shaped article again.
The utility model content
The purpose of this utility model is, at the deficiency of above-mentioned existing injection mold, provides a kind of simple in structure, alleviates the injection mold of intensity of workers, operation is few and production efficiency is high automatic excision waste material.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of injection mold of automatic excision waste material, it comprises that a die holder and is arranged on the core rod on this die holder, pouring slot place in the corresponding described core rod of this die holder is provided with a cutoff device, and is provided with one in this cutoff device rear and can drives the drive unit that it carries out the blank action.
Described cutoff device comprises that a slide block and a head are the cutting knife mold insert of blade-like, this cutting knife mold insert upper end is stretched into watering of described core rod and is expected the inboard, road, the lower end is provided with the oblique chute that a cross section is one " T " font, and be provided with in described slip front and match with this oblique chute, cross section is the obliquity prominence platform of one " T " font, described cutting knife mold insert is vertically set on the obliquity prominence platform of this slide block by oblique chute, and can correspondingly move up and down with sliding before and after the described slide block.
Described drive unit comprises that a support plate and is fixed on the miniature oil cylinder on this support plate, the drive rod of described miniature oil cylinder is connected with described slide block, in described die holder to position that should the slide block trailing flank be provided with one can this miniature oil cylinder work of this control the electronic journey switch.
It also comprises a thimble, and this thimble one end is a wedge shape, and run through that described die holder stretches into described core rod water the material road, and be provided with the strip through hole that can allow this push rod pass in described slide block, the length of this strip through hole is slightly larger than the propelling stroke of described slide block.
The beneficial effects of the utility model are: the utility model is simple in structure, be provided with cutoff device and drive unit at the pouring slot place, the product that can when formed product stub bar be removed after making moulding does not automatically have the running channel stub bar, improved production efficiency, the automaticity height, labour intensity is little, has reduced the operation in the back procedure for processing, when saving lot of manpower and material resources, and guarantee product quality.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
