Abstract
The utility model discloses the injection mold utilizing liquid hot cutting pouring gate, include fervent mould, fervent mould inside is provided with cutting knife, fervent mould is outside equipped with super-pressure time schedule controller, the output of super-pressure time schedule controller is communicated with fervent mould inner formword oil circuit by high-pressure oil passage, the folding mould touch switch be provided with by fervent mould provides matched moulds signal to input to super-pressure time schedule controller, cutting knife rear end is connected with small-bore cylinder, small-bore cylinder can promote small-bore cylinder inner carrier and advances and then drive cutting knife to realize earnestly operation under the driving of super-pressure time schedule controller.Plastic product, after filling compression (feeding) completes, in die cavity in the uncooled situation of product, is separated with cast gate by injection machine.Product now or liquid condition is less to appearance effects, simultaneously minimum to the wearing and tearing of cutting knife, and can the dwell time be saved.
Description
Technical field
The utility model is applied to injection mould field, specifically about the mould ingate thermal release before mould die sinking.
Technical background
Before 2008, we generally use 4 pieces of ejector retainner plates or mechanical linkage which controls, but take up room large, thrust is not enough, weak effect, cost are expensive, difficult in maintenance, belongs to pre-top earnestly.Bring into use gas fervent after 2008, namely gas boosting reaches 40-60MPA.Although earnestly effective, volume is large, cutter structure is complicated, cost is high, difficult in maintenance, range of application is limited.
Utility model content
For above-mentioned technological deficiency, the purpose of this utility model is: utilize liquid fervent, when fluid pressurization, pressure reaches 80-100MPA, little and the completely standardization of volume, strengthen range of application while reducing technical threshold and maintenance cost, Here it is, and liquid is fervent, is that cast gate scheme cut by a kind of mould of practical.
Above-mentioned purpose is achieved through the following technical solutions:
Utilize the injection mold of liquid hot cutting pouring gate, include fervent mould, fervent mould inside is provided with cutting knife, it is characterized in that: earnestly mould is outside equipped with super-pressure time schedule controller, the output of super-pressure time schedule controller is communicated with fervent mould inner formword oil circuit by high-pressure oil passage, the folding mould touch switch be provided with by fervent mould provides matched moulds signal to input to super-pressure time schedule controller, cutting knife rear end is connected with small-bore cylinder, and small-bore cylinder can promote small-bore cylinder inner carrier and advances and then drive cutting knife to realize earnestly operation under the driving of super-pressure time schedule controller.
The upper end of described cutting knife is elongated strip, and lower end is fixed in cutter sleeve.
The cutting knife face of described cutting knife and the cover half face of fervent mould are reserved with gap, and cutting knife can be avoided in cutting-off process to clash into cover half surface, and cutting can separating flow tract and product completely.
Most of redundant rubber stock, towards 45 jiaos, mould inner flow passage direction, can be squeezed in runner by described cutting knife in the process of extruding.
, air heat cut ratio fervent with reservation, liquid heat cutter of the present utility model has a clear superiority in, and please see figure below:
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present utility model;
Fig. 2 is utility model works principle schematic;
Fig. 3 is the fervent front cutting knife of the utility model and product space schematic diagram;
Fig. 4 be the utility model earnestly after cutting knife and product space schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ 4, utilize the injection mold of liquid hot cutting pouring gate, include fervent mould 1, fervent mould 1 inside is provided with cutting knife 2, fervent mould 1 is outside equipped with super-pressure time schedule controller 3, the output of super-pressure time schedule controller 3 is communicated with fervent mould 1 inner formword oil circuit 11 by high-pressure oil passage 31, and the folding mould touch switch 12 be provided with by fervent mould 1 provides matched moulds signal to input to super-pressure time schedule controller.Cutting knife 2 rear end is connected with small-bore cylinder 4, and small-bore cylinder 4 can promote small-bore cylinder 3 inner carrier and advances and then drive cutting knife 2 to realize fervent operation under the driving of super-pressure time schedule controller 3.
As shown in Fig. 3 ~ 4, the upper end 21 of described cutting knife 2 is elongated strip, and lower end is fixed in cutter sleeve 22.The cutting knife face of described cutting knife 2 and the cover half face of fervent mould 1 are reserved with gap, and cutting knife 2 in cutting-off process can be avoided to clash into cover half surface, and can separating flow tract and product completely.Most of redundant rubber stock, towards 45 jiaos, mould inner flow passage direction, can be squeezed in runner by described cutting knife 2 in the process of extruding.Touching between product 5 and runner wears distance 0.05mm, can ensure that product and runner are automatically separated and do not produce burr.Plastic product 5, after filling compression (feeding) completes, in die cavity in the uncooled situation of product, is separated with cast gate 13 by injection machine.Product now or liquid condition is less to appearance effects, simultaneously minimum to the wearing and tearing of cutting knife 2, and can the dwell time be saved.The utility model can improve cast gate surface quality, shortens molding cycle, improves moulding process, simplifies mould structure, improves production stability, reduce human input.
