the achievement of the objects, functional features and advantages of the present utility model will be further described with reference to the accompanying drawings, in conjunction with the embodiments.

Detailed Description

The utility model provides a die structure for conveniently exchanging inserts.

Referring to fig. 1 to 3, fig. 1 is a sectional view illustrating a structure in which an embodiment of the present utility model is normally operated, fig. 2 is an assembly structure of an insert, a connecting rod, and a draw rod in an embodiment of the present utility model, and fig. 3 is a sectional view illustrating a structure in which an embodiment of the present utility model is normally replaced.

As shown in fig. 1-2, in an embodiment of the present utility model, the mold structure for facilitating exchange of inserts includes: the rear mold core 2 is arranged on the rear mold plate 1 of the mold, the insert 3 is embedded on the parting surface at the top of the rear mold core 2, the bottom of the insert 3 is fixedly connected with the connecting rod 5 through the headless screw 4, and the bottom end of the connecting rod 5 vertically penetrates through the rear mold core 2 and the rear mold plate 1. The headless screws 4 are adopted for connection, the connection strength is high, the connection is stable, and the screws cannot be exposed to interfere with the inner wall of the rear mold core 2.

The bottom horizontal slip of back template 1 is equipped with pull rod 6, and the below of connecting rod 5 is arranged in to the first end of pull rod 6, and the second end of pull rod 6 is fixed on the lateral wall of back template 1, and pull rod 6 can follow the pull back upset direction reinsertion of back template 1, and the tip threaded connection of the second end of pull rod 6 has pull ring 7, makes things convenient for this pull rod 6. A T-shaped groove 8 is formed in the first side face of the first end of the drawing rod 6, a limit cap 9 is arranged at the bottom end of the connecting rod 5, and when the die is normally produced, the T-shaped groove 8 faces upwards to clamp the limit cap 9 into the T-shaped groove 8, so that the connecting rod 5 and the insert 3 are fixed.
