Abstract
The utility model relates to the field of forging dies for forging and pressing, in particular to a split type cross-shaped piston die. The split type cross-shaped piston die comprises a die outer shell (1) and is characterized by further comprising a protruding column (2), inner embedding blocks (3) and a bottom cutting board (4). The protruding column (2) is perpendicularly fixed on the bottom face of the interior of the die outer shell (1), the inner embedding blocks (3) are embedded on the lateral wall of the die outer shell (1) through dovetail grooves, the inner embedding blocks (3) are evenly distributed around the central axis of an inner cavity of the die outer shell (1), a through hole is formed in the center of the bottom cutting board (4), four embedding block grooves are sequentially formed in the periphery of the bottom cutting board (4), the protruding column (2) is sleeved with the through hole in the center of the bottom cutting board (4), the four inner embedding blocks (3) are embedded in the four embedding block grooves in the bottom cutting board (4) respectively, and the outer edge of the bottom cutting board (4) is adhered to the inner lateral wall of the die outer shell (1). The split type cross-shaped piston die is simple in structure, low in cost, convenient to manufacture, high in forged piece accuracy and high in adaptability.
Description
Technical field
The utility model relates to the forging die field for forging and pressing, is specially a kind of split type cross Piston mould.
Background technology
Be used for the present multiplex forging and pressing manufacturing of piston of automobile brake system.Brake is comparatively complicated with the bottom shape of piston, and the piston base size different accuracy of all size requires also different, have following two problems when adopting forging and pressing: 1. die life is short, be difficult to adapt to production continuously in enormous quantities, the mould early fatigue is damaged, make forging produce harmful burr, need to increase unnecessary doing over again or the exhaustive test operation; 2. die manufacturing cost is high, and complicated shape need to rely on the special process means such as electric spark, has increased simultaneously the difficulty of mold polish, be difficult to die life be guaranteed, even if mould is partially damaged and also needs integral replacing, and the waste manufacturing cost.
The utility model content
In order to overcome the defective of prior art, provide a kind of simple in structure, easily manufactured, use flexibly, forging precision is high, the forging die of long service life, the utility model discloses a kind of split type cross Piston mould.
The utility model reaches goal of the invention by following technical solution:
A kind of split type cross Piston mould comprises mold shell, it is characterized in that: also comprise projection, in insert and the bottom anvil plate,
Projection is vertically fixed on the bottom surface of mold shell inside, the central axes of the central axis of projection and mold shell inner chamber;
In insert and have four, in insert and all be embedded on the sidewall of mold shell by dovetail groove, in insert and be evenly distributed around the central axis of mold shell inner chamber,
The center of bottom anvil plate has through hole, and the surrounding of bottom anvil plate has four insert grooves successively, and the central through hole of bottom anvil plate is enclosed within on projection, inserts for four to be embedded in respectively in four insert grooves of bottom anvil plate, and the outer rim of bottom anvil plate and the madial wall of mold shell are fitted.
Described split type cross Piston mould is characterized in that: between the central through hole of bottom anvil plate and projection and insert and the insert groove of bottom anvil plate between all adopt interference fit.
The utility model adopts split-type structural, and each parts first adopt the processing of line cutting mode, implement polishing after completion of processing.During use, in the inner chamber of mold shell, the top of bottom anvil plate, by the madial wall of mold shell, projection and in insert that to have consisted of the cross section be cross impression, blank is placed in impression, can implement to forge and press operation; If the size of change forging, can with in insert and unload, be replaced with other sizes and get final product.The maintaining separately of each parts.
The beneficial effects of the utility model are: simple in structure, cost is low, is convenient to make, and forging precision is high, strong adaptability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below further illustrate the utility model by specific embodiment.
Embodiment 1
A kind of split type cross Piston mould, comprise mold shell 1, projection 2, in insert 3 and bottom anvil plate 4, as shown in Figure 1, concrete structure is:
Projection 2 is vertically fixed on the bottom surface of mold shell 1 inside, the central axes of the central axis of projection 2 and mold shell 1 inner chamber;
In insert and 3 have four, in insert and 3 all be embedded on the sidewall of mold shell 1 by dovetail groove, in 3 central axis around mold shell 1 inner chamber of inserting be evenly distributed;
The center of bottom anvil plate 4 has through hole, the surrounding of bottom anvil plate 4 has four insert grooves successively, the central through hole of bottom anvil plate 4 is enclosed within on projection 2, inserts for four 3 to be embedded in respectively in four insert grooves of bottom anvil plate 4, and the madial wall of the outer rim of bottom anvil plate 4 and mold shell 1 is fitted.
In the present embodiment, between the central through hole of bottom anvil plate 4 and projection 2 and insert 3 and the insert groove of bottom anvil plate 4 between all adopt interference fit.
The utility model adopts split-type structural, and each parts first adopt the processing of line cutting mode, implement polishing after completion of processing.During use, in the inner chamber of mold shell 1, the top of bottom anvil plate 4, by the madial wall of mold shell 1, projection 2 and in insert 3 to have consisted of the cross section be cross impression, blank is placed in impression, can implement to forge and press operation; If the size of change forging, can with in insert and 3 unload, be replaced with other sizes and get final product.The maintaining separately of each parts.
