Adjustment blocks for die structure design
The general requirements of mold structure design mold structure design should be based on product structure, technical requirements, equipment conditions to adopt different processing methods, of course, the structural design of the New Year should also check processing technology.
We usually have high requirements for product appearance shape of cavity, USES the electric spark machining, the shape of cavity with the form, when doing the electrode on five each corner when the circular arc transition, in order to improve the aesthetic of the product so that the form and the intensity of cavity, and the volume of the mould is reduced for some complex shape product, the appearance of not high demand product shape cavity the hook set spell, so easy to machining, but also has a drawback, the mould structure is more complex, and the volume is larger,The manufacturing cost of the mold is relatively high. The matching structure of the mold's concave and convex die is the most important part in the structural design of the compression mold.Adjustment block: to ensure the depth of the convex block size, so that the die will not be extruded and deformation or damage, the thickness of the adjustment block should be large at the beginning, in the trial.The horizontal force of the product shall be generally around 0.050. LMLN.
Feeding room: is for loading DMC molding material, its loading capacity to move to ensure loading after pressing products used in raw materials have the space of about 1 mm, in order to prevent the raw material in the process of suppression chamber can generally are an extension of the shaped cavity dean mass of the sample for the shape of cavity structure of complex products, shape of the cavity machining difficulty will increase, the processing fee will be greatly improved, so we for this type of mould loading chamber is separated from shaped cavity.The material of the feeding chamber is tempered after forging, and the hardness is about HRC3032.To mould processing hard nitriding processing, after the completion of such loading chamber is both easy to machining, and reduced the cost in addition, the feed chamber should add R15 surrounded by a top of the arc of R3, add the single side slope at the same time, the depth of the slope section is about 10 NLNL commonly, so beneficial to punch into people, reduce the concave and convex mold force of friction material room and convex touch mould dimension should be according to the raw material of liquidity and the size of the die size, generally take unilateral clearance between 0.05 mm - LMM.
