Abstract
The utility model discloses a kind of casting spinning backform of improvement, comprise adapter sleeve (1), spring retaining sleeve (2), discharging spring (3), unloading block (5) are set, discharging spring (3) is arranged in spring retaining sleeve (2), unloading block (5) is arranged at discharging spring (3) lower end, and unloading block (5) contacts with blank (6).The utility model shortens the technological process of production, former technological process " die casting-remove cast gate-spinning " is reduced to " die casting-spinning ", improves efficiency; Reduce Birmasil product deflection; Eliminate Birmasil product and be stained with the problem generation being molded as production line and stopping production.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to spin forming die.
Background technology
In automotive hub production process, rotary extrusion aluminum alloying technology is the production technology that the world is leading, and along with the swift and violent growth of aluminium alloy wheel hub output is revolved in casting, cast article is speed-raising completely, pre-machined sequence output strengthens thereupon, and spinning operation needs to enhance productivity to meet preorder and produces.
The casting spinning backform of prior art realizes being separated of backform and blank by ejector and guiding mandrel, and when backform pressure is excessive, this mould structure easily causes that blank is out of shape, backform cannot release problems.
Summary of the invention
The utility model object is to provide the casting spinning backform of a improvement.
Concrete scheme of the present utility model is, the casting spinning backform of improvement, comprises adapter sleeve, arranges spring adapter sleeve, discharging spring, unloading block, and discharging spring is arranged in spring adapter sleeve, and unloading block is arranged at discharging lower spring end, and unloading block contacts with blank.
At the blank shaping initial stage, blank extruding unloading block, unloading block extruding discharging spring, discharging spring contraction, blank shaping latter stage, discharging spring reset, blank ejects by unloading block, and backform is separated with blank.
The utility model does not increase equipment, does not affect forging process productive temp, shortens the technological process of production, former technological process " die casting-remove cast gate-spinning " is reduced to " die casting-spinning ", improves efficiency; Reduce Birmasil product deflection; Eliminate Birmasil product and be stained with the problem generation being molded as production line and stopping production.
Accompanying drawing explanation
Fig. 1 is prior art casting spinning backform schematic diagram.
Fig. 2 is the casting spinning backform schematic diagram that the utility model improves.
In figure: 1-adapter sleeve, 2-spring retaining sleeve, 3-discharging spring, 4-backform, 5-unloading block, 6-blank.
Detailed description of the invention
As shown in Figure 2, the casting spinning backform of improvement, comprises adapter sleeve 1, arranges spring retaining sleeve 2, discharging spring 3, unloading block 5, and discharging spring 3 is arranged in spring retaining sleeve 2, and unloading block 5 is arranged at discharging spring 3 lower end, and unloading block 5 and blank connect 6 and touch.
The blank shaping initial stage, blank extruding unloading block 5, unloading block 5 extrudes discharging spring 3, and discharging spring 3 shrinks; Blank shaping latter stage, discharging spring 3 resets, and blank ejects by unloading block 5, and backform is separated with blank.
