Description
Technical Field
The utility model relates to the field of mold equipment, in particular to a one-step forming submarine gate structure of a flip-chip double-color mold.
Background
The gate, also called the feed port, refers to the section of the channel from the runner to the mold cavity, being the smallest and shortest section of the gating system. In metal casting, molten metal enters the inlet and passage of the mold during casting. Often referred to generally as a gating system. The effect of accelerating the feeding by utilizing the compacting flow surface is that the high shearing rate can ensure good feeding fluidity; the heating effect of viscous heating also has the effects of increasing the material temperature and reducing the viscosity. After the molding is finished, the pouring gate is solidified and sealed at first, and the functions of preventing the feeding from flowing back and preventing the cavity pressure from dropping too fast so as to enable the molded product to shrink and dent are achieved. After molding, the runner system and the molded part are conveniently sheared off.
At present, chinese patent discloses an injection moulding mould of printer casing injection molding on net, and publication number CN215825863U includes roof, front bezel, back template, two backup pads, thimble board, bottom plate, two sets of diagonal rod ejection mechanism and a plurality of first side core-pulling mechanism of group, and casing core side end is equipped with a plurality of first side core-pulling mechanism of group, and diagonal rod ejection mechanism top passes back template and with the butt of casing core, and first side core-pulling mechanism includes first line insert, two first side dog, first diagonal guide pillar and first reset spring. When the die is opened, the inclined guide post of the side core-pulling mechanism is pulled away from the slide insert, the slide insert moves towards the injection molding piece under the action of the elastic force of the reset spring, and the inclined rod ejection mechanism moves upwards simultaneously to eject the injection molding piece, so that the injection molding piece is prevented from being adhered to the surface of the slide insert, and the ejection efficiency and the production quality of a product are improved; the side stop block arranged in the side core pulling mechanism improves the sliding stability of the slide insert and prevents the slide insert from shaking during core pulling to influence the structural quality of the injection molding.
The injection molding mold for the injection molding piece of the printer housing in the above patent has the advantage of high stability, but after a color product is molded, the injection molding mold is opened, the product is left to rotate 180 degrees on the rotating side, then is matched with the fixed side of the secondary molding, the secondary product is injected, and after the secondary injection molding is finished, the product is left on the fixed side and is ejected. Because the one-time molded product and the gate leave the fixed side and leave the rotating side, the common mold is a point gate or a side gate, but many products are appearance surfaces, the point gate is not designed in space, the side gate has a process of shearing the gate in the later period, the reject ratio of the product is increased, and the cost is increased. There are many times when a submarine gate needs to be selected and the submarine gate needs to be separated from the product during the mold opening process. If the submarine gate is designed on the rotating side, the gate and the product are not disconnected and can be left on the rotating side, then the product after the secondary molding breaks the submarine gate and can be left on the fixed side of the secondary molding, and the submarine gate formed once can not be taken out by a manipulator.
Disclosure of Invention
The utility model aims to solve the problem that the traditional injection molding die cannot avoid the later-stage manual gate shearing in the prior art, and provides a flip-chip double-color-die one-step molding submerged gate structure with the advantage of avoiding the later-stage manual gate shearing.
The utility model discloses a one-time molding submarine gate structure of a flip-chip double-color mold, which comprises a pull rod, wherein a large fixing plate for installing the pull rod is arranged at the right end of the pull rod, a large ejector plate for driving the pull rod is arranged at the right end of the large fixing plate, a cross water supporting needle matched with the pull rod is arranged at the left side of the pull rod, a runner matched with the cross water supporting needle is arranged at the left end of the cross water supporting needle, a submarine gate matched with the submarine gate is arranged at the left end of the runner, a small fixing plate for installing the cross water supporting needle is arranged at the right end of the cross water supporting needle, and a small ejector plate matched with the pull rod is arranged at the right end of the small fixing plate.
Preferably, the large fixing plate is connected with the large thimble plate through an inserting guide post, guide sleeves for inserting the guide post are respectively embedded on the large fixing plate and the large thimble plate above the pull rod, and an installation groove for embedding the right end part of the pull rod is formed in the large fixing plate.
Preferably, the small fixing plate and the small ejector plate below the cross water supporting mouth needle are respectively provided with a connecting groove for embedding the left end of the pull rod, and the small fixing plate and the small ejector plate above the connecting groove are respectively provided with a movable groove for embedding the cross water supporting mouth needle right end cross supporting part.
Preferably, the left end of the cross water supporting mouth needle is provided with a 3-degree back-off pulling well matched with the runner.
In order to prevent the runner from following the rotating side due to the fact that the runner and the product are not broken, the utility model adds a submarine gate structure, and the runner formed at one time is left on the fixed side. When the mould is opened, the product leaves the fixed side and leaves the rotating side under the action of the ejector pin, the runner is motionless, the separation of the submarine gate and the product is realized, the runner is required to be reversely buckled, the large ejector pin plate is ejected by utilizing the vacancy of the cross water supporting mouth needle, the ejection is carried out by 11mm before ejection, the product is ejected by 11mm, and the runner is motionless, and the submarine gate and the product are separated. After 11mm ejection, the small ejector plate touches the cross water supporting mouth needle, the cross water supporting mouth needle starts ejection, the runner ejects the mold core, the runner formed once and the product formed secondarily are both at the fixed side, and can be taken out together by adopting a mechanical arm. When the large thimble plate retreats, the small fixing plate can press the cross support of the cross support nozzle needle to pull the nozzle needle back.
The cross water supporting mouth needle is arranged below the hot runner flow dividing plate, the die adopts a small thimble plate mode, is arranged below the hot runner and is connected with the large thimble plate through a pull rod, so that synchronous movement is realized.
The cross water-holding mouth needle is at the beginning stage of ejecting of the product, the mouth needle is motionless with the runner, the product is disconnected with the submerged arc, after the product is ejected by 11mm, the mouth needle begins ejecting, the runner is ejected out of the mould core, the runner is left at the one-step forming fixed side, and the manipulator is convenient to take the runner.
In order to prevent the gate and the product from being disconnected, the runner is enabled to follow the rotating side, the 3-degree back-off pulling well of the runner is back-off, and the runner is pulled to be not enabled to follow the product. By adopting the submerged arc gate, the submerged arc gate can be effectively prevented from being manually sheared in the later stage, or a robot is manufactured to shear the submerged arc gate, so that the cost is reduced, the automatic production is realized, and the efficiency is improved.
The utility model has the following beneficial effects: the step of manually shearing the pouring gate in the later period is omitted, the production efficiency is improved, the structure is simple, and the use is convenient.
