Description

The mold mechanism of side gate is automatically cut off in mould
Technical field
The present invention relates to plastic injection moulding mould and the gate cutting of die cast metal mould, it is the mold mechanism automatically cutting off side gate in mould.
Background technology
The demand that modern injection produces and Die Casting requires mould must to be fulfilled for automated production, it is desirable in injection or press casting procedure, runner waste material and goods separate automatically.In order to realize this purpose, a lot of goods use TOP-TIP to water goods are enterprising, spot pouring mouth or tunnel gate, but the raw-material function of different molding is different to the requirement of cast gate, the particularly plastics of some poor fluidities: as Merlon, PVC-U, polyphenylene oxide, poly-vitriol, fluoroplastics are not suitable for using above-mentioned cast gate molding, therefore adopt side gate to enter to water form.Side gate is a kind of conventional gate form, accounts for about the 2/3 of moulded products sum.Side-gate mold simple in construction, the manufacturing cycle is short, cost is low.But the solidifying material that existing side-gate mold is typically all goods and running gate system connects together outside launch mode, then manual or special tool is adopted to remove the solidifying material of running gate system, this process carrying out secondary operations outside mould very easily causes the cosmetic injury of goods, there will be that gate cutting face is irregular, cast gate is torn simultaneously, the problems the such as therefore scrappage of goods is high, and labor strength is big, production cost is high occur.In order to improve quality of item, reducing production cost, reduce labor strength, I combines and manufactures and designs experience for many years, and spy provides a kind of mold mechanism at mould inside automatic break gate as follows to solve the problems referred to above.
Summary of the invention
The present invention automatically cuts off the mold mechanism of side gate in mould, it is to utilize the cutting knife (15) being arranged on dynamic model one side when injector and die casting machine die sinking eject goods, cutting knife (15) cuts off solidifying to goods (4) and running gate system material (5) separately, then by the ejecting mechanism of mould by outside goods (4) and running gate system solidifying material (5) launch mode.The mold mechanism of side gate is automatically cut off in mould, it provides the benefit that: this cutter is suitable for metal die-casting mold and plastic injection mould automatically cuts off side gate in mould, its simple in construction, production stability are good, alleviate the labor intensity of workman, improve the presentation quality of goods, it is to avoid the problem of scrapping goods in mould external cutting off cast gate process.Automatically cut off the mold mechanism of side gate in mould, solve when existing side-gate mold excises cast gate outside mould that labor strength is big, products appearance is of poor quality and scraps the problem of goods.The mold mechanism of side gate is automatically cut off in mould, it is characterized in that: it is made up of fixed half and moving half two parts, its cover half part is by top clamping plate (1), solid plate (2), cover half mold

Two, the operating principle of this mould is: be arranged on injector or die casting machine when mould, after moulding by casting, pressurize feeding, cooling and shaping, move after injector or die casting machine driven mold dynamic model part, in this moving process, first spring (13) loses pressure, then push rod (14) is upspring under the effect of the first spring (13), and solidifying for running gate system material (5) is pushed to dynamic model one side.Goods (4) are buckled in insert (375) and are pulled to dynamic model one side simultaneously.When die sinking spacing more than do not affect the solidifying material (5) of goods (4) and running gate system drop out mould outer time, dynamic model part is mobile after stopping to be made.At this moment injector or die casting machine push rod (98) promote the second thimble backing plate (19) to drive the first thimble (12), the second thimble (21), the second spring (23) up;Now, first thimble (12) promotes goods (4) to take off insert (375), second spring (23) promotes the first thimble backing plate (17) to drive the cutting knife (15) being arranged on the first ejector retainner plate (16) up simultaneously, in This move process, cutting knife (15) cuts off solidifying to goods (4) and running gate system material (5) from the edge of goods (4).When continuing to release, goods (4) by the first thimble (12) launch mode outside, and at this moment the solidifying material (5) of running gate system is also attached on cutting knife (15), needs two-step ejecting.When second time is released, collide with the lower plane of moving platen (6) in the upper surface of locating part (22) owing to being arranged on the first ejector retainner plate (16), limit the first ejector retainner plate (16) and the first thimble backing plate (17) is up, also stop up action in the cutting knife (15) being mounted on the first ejector retainner plate (16).Injector or die casting machine push rod (98) continue to press on the second thimble backing plate (19) and drive the second thimble (21) of being arranged on the second ejector retainner plate (18) solidifying for running gate system material (5) from outside launch mode cutting knife (15).After completing one-time cast-forming, when mould resets, it is injector or die casting machine driven mold dynamic model part does action contrary during die sinking, first it is that the end face of push back pin (8) is collided with the lower plane of solid plate (2), then the propulsive thrust of solid plate (2) promotes push back pin (8) to drive the first thimble backing plate (17) to promote the second spring (23) to drive the second ejector retainner plate (18) to make homing action, in This move process, it is arranged on the cutting knife (15) on the first ejector retainner plate (16) and the first thimble (12) and the second thimble (21) being arranged on the second ejector retainner plate (18) returns to beginning initial conditions with the reset of the first ejector retainner plate (16) and the second ejector retainner plate (18).
Three, the structure of cutting knife (15) and the selection manufacturing steel
Due in actual production, the every die sinking of cutting knife once must cut off a cast gate, then the intensity of cutting knife and hardness are crucial, if cutting knife (15) is intensity or hardness not, when cutting side cast gate, soft flocks can be left, the surface albefaction of goods, the problem even occurring can't cut after excision after product sprue excision.For the problems referred to above, then the cutting knife of this mould is when steel are selected materials, first 8407A type, by being heat-treated to the hardness of 58 60HRC.The front end of cutting knife (15) arranges inclined-plane at 45 °, and the blade of cutting knife (15) is arranged to arc surface.By this mold mechanism of above-mentioned enforcement not only can in mould automatic break gate, and after excising cast gate, the excision trace not albefaction on goods and produce soft flocks.
