Abstract
The utility model relates to a compression molding die field, in particular to compression molding die of removable module unit. The device consists of an upper die (2), a replaceable boss (1) and a lower die (4); the replaceable boss (1) is composed of three sections, the tail section forms the appearance of a die cavity of the upper die (2), the middle section is a circular table, the front section is a square boss, and the square boss is concavely combined with a square groove of the upper die (2); the round table of the middle section is recessed with the round groove of the upper die (2); the radial displacement of the replaceable boss (1) is limited, the upper die (2) is fixedly connected with the replaceable boss (1) through the bolt (3), and the upper die and the lower die (4) form an integral die. On the one hand, the raised portions in the mold can be changed as appropriate. On the other hand, the whole service life of the die can be prolonged, and the processing cost is saved.
Description
Technical Field
The utility model relates to a compression molding die field, in particular to compression molding die of removable boss module.
Background
The mould has a specific inner cavity size, the blank becomes a finished piece tool with a specific shape and size when the external force is applied, the tool for obtaining a required product in the mould pressing method in industrial production realizes the shape processing of an object by changing the physical state of a formed material. The mold generally comprises a movable mold and a fixed mold which can be combined or separated.
Because the die is a precise tool, the shape is complex, the expansion force of the blank is large, and the bulge part in the die cavity can be seriously deformed under the conditions of high temperature and high stress for a long time, so that the processing precision can not meet the requirement.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes shortcoming among the prior art provides a removable module unit's compression mold.
Technical scheme
A mould pressing mould of a replaceable module unit comprises an upper mould 2, a replaceable boss 1 and a lower mould 4; the replaceable boss 1 is composed of three sections, the tail section forms the appearance of a die cavity of the upper die 2, the middle section is a round table, the front section is a square boss, and the square boss is recessed with a square groove of the upper die 2; the round table of the middle section is recessed with the round groove of the upper die 2; the radial displacement of the replaceable boss 1 is limited, the upper die 2 is fixedly connected with the replaceable boss 1 through the bolt 3, and the upper die and the lower die 4 form an integral die.
The upper die 2 is provided with bolt through holes.
The replaceable boss 1 is designed with a threaded hole.
The replaceable boss 1 is made of die steel 5 CrNiMo.
The upper die 2 is also provided with a groove which is coaxial with the bolt through hole.
The depth of the groove is larger than the height of the bolt head, and the groove is used for hiding the bolt.
The depth of the threaded hole is the sum of the heights of the round table and the square boss, and reliable connection of threads is guaranteed.
The axis of the circular truncated cone, the center of the square boss and the axis of the threaded hole are coaxial, so that the best connection strength between the replacement boss 1 and the upper die 2 is ensured.
Technical effects
The utility model relates to a removable module unit's compression mold, on the one hand, can change according to the situation to bulge in the mould. On the other hand, the whole service life of the die can be prolonged, and the processing cost is saved.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 5 and 6, in the present embodiment, a mold for molding a replaceable module unit,
the square boss on the replaceable boss 1 is recessed with the groove of the upper die 2 to limit axial rotation, and the round table at the middle section is recessed with the circular groove of the upper die 2; restriction removable boss 1 radial displacement, insert bolt 3 along last through-hole on the mould 2 from last to down, until the removable boss 1 of screw in's screw hole and screw up, make removable boss 1 and last mould 2 link firmly, because square boss on the removable boss 1, circular boss is with the recess of last mould 2 after closing, guarantee that removable boss 1 can't rotate and the drunkenness relatively last mould 2 under the effect of blank stress, when changing 1 damage of boss, through taking off bolt 3, break away from removable boss 1 from last mould 2, install new removable boss 1 again, the part machining precision has been guaranteed.
