Description
Technical field
The present invention relates to plastic injection moulding mould and the cast gate of die cast metal mould
Cut-out, it is the mold mechanism that side gate is automatically cut off in mould.
Background technology
Modern injection production and Die Casting requirement mould must are fulfilled for automated production
Demand, it is desirable in injection or press casting procedure, runner waste material and product are separated automatically.
In order to realize this purpose, many products are poured product is enterprising using TOP-TIP, point
Cast gate or tunnel gate, but different shaping raw material requirement of the function to cast gate not
Together, particularly plastics of some poor fluidities：Such as makrolon, PVC-U, gather
Phenylate, poly- alum, fluoroplastics are not suitable for being molded using above-mentioned cast gate, therefore use side gate
Enter to pour form.Side gate is a kind of conventional gate form, accounts for moulded products sum
2/3 or so.Side-gate mold simple structure, manufacturing cycle be short, low cost.But it is existing
The condensate for having side-gate mold typically all product and running gate system connects together launch mode
Outward, the condensate of running gate system is then removed using manual or special tool, it is this in mould
The cosmetic injury of product is easily caused during carrying out secondary operation outward, while occurring
Gate cutting face is irregular, cast gate tear, therefore the scrappage of product is high, Gong Renlao
The problems such as fatigue resistance is big, production cost is high occurs.In order to improve quality of item, life is reduced
Cost is produced, reduces labor strength, I combines and manufacture and design experience for many years, and spy carries
Above-mentioned asking is solved for a kind of following mold mechanism in mould inside automatic break gate
Topic.

State the upper surface of locating part (22) in pushing out product with the lower plane of moving platen (6)
It is close to, first ejector retainner plate (16) and the first thimble backing plate (17) are with the 7th screw
(176) it is fastenedly connected, the rubbish part (376) and Bottom clamp plate (10) are with the 5th
Screw is fastenedly connected.
2nd, the operating principle of the mould is：When mould installion is in injector or die casting machine,
After moulding by casting, pressurize feeding, cooling and shaping, injector or die casting machine driven mold
Moved behind dynamic model part, in this moving process, the first spring (13) loses pressure,
Then push rod (14) is upspring in the presence of the first spring (13), and running gate system is coagulated
Material (5) pushes the side of dynamic model one to.Product (4) is buckled in insert (375) simultaneously
It is pulled to the side of dynamic model one.Product (4) and running gate system are not influenceed when die sinking spacing is more than
Condensate (5) is dropped out when outside mould, and dynamic model part is mobile after stopping to be made.At this moment injector or
Die casting machine push rod (98) promotion the second thimble backing plate (19) the first thimble of drive (12),
Second thimble (21), second spring (23) are up；Now, the first thimble (12)
Product (4) is promoted to be taken off from insert (375), while second spring (23)
The first thimble backing plate (17) is promoted to drive the cutting knife on the first ejector retainner plate (16)
(15) up, during This move, cutting knife (15) is product (4) and pours
Injection system condensate (5) cuts off from the edge of product (4).When continuing to release, product (4)
Outside by the first thimble (12) launch mode, and at this moment gating system of material (5) is also attached to
On cutting knife (15), two-step ejecting is needed.When releasing for second, due to installed in the first top
The upper surface of the locating part (22) on needle plate (16) and the lower plane of moving platen (6)
Collide, limit the first ejector retainner plate (16) and the first thimble backing plate (17) is up, in
The cutting knife (15) being mounted on the first ejector retainner plate (16) also stops up action.Note
Penetrate machine or die casting machine push rod (98) continues to press on the second thimble backing plate (19) and drives installation
The second thimble (21) on the second ejector retainner plate (18) is gating system of material (5)
From outside launch mode on cutting knife (15).After completing one-time cast-forming, when mould resets,
It is injector or opposite action when die casting machine driven mold dynamic model part molds, first
It is that the end face of push back pin (8) and the lower plane of solid plate (2) are collided, then solid plate
(2) propulsive thrust promotes push back pin (8) to drive the first thimble backing plate (17) to promote the
Two springs (23) drive the second ejector retainner plate (18) to make homing action, This move process
In, cutting knife (15) on the first ejector retainner plate (16) and installed in the second thimble
The first thimble (12) and the second thimble (21) on plate (18) is with the first ejector retainner plate (16)
Reset with the second ejector retainner plate (18) returns to beginning initial conditions.
3rd, the structure of cutting knife (15) and the selection for manufacturing steel
Because in actual production, cutting knife is often molded and must once cut off a cast gate, in
The intensity and hardness for being cutting knife are crucial, if cutting knife (15) not enough intensity or hardness,
When side gate is cut off, soft flocks can be left after product sprue excision, the table of product after excision
Colourless, or even there is the problem that can't cut.Regarding to the issue above, the then mould
Cutting knife in steel sorting, 8407A types first, by being heat-treated to 58-60HRC's
Hardness.The front end of cutting knife (15) sets inclined-plane at 45 °, the blade of cutting knife (15)
It is arranged to arc surface.By above-mentioned implementation, the mold mechanism can not only automatically cut off in mould
Cast gate, and after cutting off cast gate, excision trace not albefaction and generation soft flocks on product.
