Abstract
The utility model discloses a die-casting mold for two-stage demolding. The die-casting mold is mainly applied to a circular electromagnetic motor cover. A plurality of grooves are formed in the electromagnetic motor cover and the electromagnetic motor cover is an uneven product, so that when die-casting is conducted on the electromagnetic motor cover, the mold joint of a fixed mold and the mold joint of a movable mold are convex and concave. The die casting process is a high-temperature liquid metal cooling concretion process, so that in the condensation process, the product may adhere to a mold core and a demolding ejection mechanism needs to be arranged to eject the product out. According to the prior art, the direct demolding mode is commonly adopted, namely a drive oil cylinder is arranged on the fixed mold or the movable mold and drives an ejector rod to rapidly eject the product out, the product is separated from the mold core, and demolding is achieved. According to the mode, when demolding resistance is large, surface scratching of the product or deformation caused by impacting of the ejector rod is prone to occurrence. According to the die-casting die, a two-stage demolding mechanism is arranged, the demolding process is more stable, and the quality of the product is improved.
Description
Technical field
The utility model relates to a kind of die casting, particularly relates to a kind of die casting of the secondary demoulding.
Background technology
Die casting is a kind of method of casting liquid forging, a kind of technique completing on special die casting die forging machine.Its basic craft course is: the first low speed of molten metal or high-speed casting fill in the die cavity of type progressive die tool, mould has movable cavity surface, it,, along with the cooling procedure pressurization of molten metal is forged, had both eliminated the shrinkage porosity defect of contraction cavity of blank, also made the interior tissue of blank reach the Broken Crystal of forging state.The comprehensive mechanical performance of blank is significantly improved.
Die casting is exactly a kind of mould that is specifically designed to die casting.It is made up of fixed half and moving half conventionally, and cover half is fixed on compression chamber of die casting machine one side's top clamping plate, is the part that molten metal starts to enter compression mod die cavity, is also one of place part of compression mod die cavity.On cover half, there is sprue to be directly connected with nozzle or the pressure chamber of die casting machine.Dynamic model is fixed on the Bottom clamp plate of die casting machine, separates and closes up to left and right mobile with Bottom clamp plate with cover half, generally looses core and establishes therein with foundry goods ejecting mechanism.
In prior art, in the PCT patent application that is 201180068965.9 in the patent No., the Toyota Motor Corporation rep. of Japan discloses a kind of die-cast device, there is fixed mould and the moveable die of shape casting product, in the movable main mould of moveable die, be provided with the mold insert of the convex form part of shape casting product in the mode that can slide, die-cast device is characterised in that, moveable die has: product ejector unit, and described product ejector unit is used for making cast article from movable main mold releasability; Mold insert mobile unit, described mold insert mobile unit makes mold insert move to the stripping direction of cast article; Protuberance demoulding unit, described protuberance demoulding unit makes convex form part from the mold insert demoulding, the control module of the action by controlling product ejector unit, mold insert mobile unit and protuberance demoulding unit is carried out the first stripping process and the second stripping process, in described the first stripping process, make cast article from movable main mold releasability by product ejector unit, and make mold insert along with cast article moves by mold insert mobile unit, in described the second stripping process, make convex form part from the mold insert demoulding by protuberance demoulding unit.
But, die casting in above-mentioned patent, although disclose a kind of method of the secondary demoulding, but also inapplicable a kind of surface has groove, uneven whole product, this is due in the time processing the product of this surface irregularity, the shape of die cavity is also equally rough with shape of product, so in the time of parting, product had both likely sticked on die cavity, also likely stick in the surface of dynamic model or cover half, if parting by force, likely can cause product surface to scratch, the die casting of above-mentioned patent is just provided with mould emptier on the dynamic model at core place.In addition, adopt the secondary mould emptier of above-mentioned patent, in fact its protuberance demoulding unit is exactly a push pedal, need to be for the push pedal of each different product design given shape, and processing is got up pretty troublesome, and applicable surface is little.
