Detailed ways

The utility model will be further described below in conjunction with embodiment (accompanying drawing):

As shown in Figures 1 and 2, the utility model’s easy-to-take hot extrusion die includes two parts: a punch and a die. Press the punch 3; the die part includes a lower template 10 processed with a central through hole, and a die fixing plate 4 fixedly installed on the top of the lower template 10, and a circular concave hole is sequentially processed on the die fixing plate from top to bottom. Groove, a longitudinal groove with a rectangular cross-section, the bottom surface of the longitudinal groove is provided with a through hole coaxial with the central through hole of the lower template 10 and the aperture is equal, and a thickness and a longitudinal groove are placed in the longitudinal groove. The push-pull slider 8 with the same groove depth is seated with a hollow cylindrical die positioning block 5 above the circular groove, and the upper part of the cavity of the die positioning block is in contact with the extrusion punch 3. Cooperate, the extrusion die 7 is placed in the lower cavity of the cavity of the die positioning block (see Figure 3), the bottom surface seat of the extrusion die 7 is placed above the push-pull slider 8, and processed on the push-pull slider 8 There is the hole of the through hole that communicates with the bottom surface of the extrusion die 7 cavity and the longitudinal groove; the middle and upper part of the outer wall of the die positioning block 5 is provided with a heater 6. The utility model is provided with a guide post 9 which cooperates with the guide sleeve phase hole 11 arranged around the upper template on the periphery of the lower template 10 .

More specifically: the upper circular inner hole of the die positioning block 5 shown in the utility model is used to place the extrusion billet; the extrusion die 7 is supported by a square push-pull slider 8, and the slider 8 is placed on the die for fixing In the longitudinal groove of the plate 4, the two cooperate with each other so that the slider 8 can perform longitudinal reciprocating movement inside the die fixing plate 4 (see Figure 2 for its structure); the extrusion die 7 is placed in the die positioning block 5 In the cavity, and under the condition that the steps on the upper part of the extrusion die 7 and the steps of the cavity of the die positioning block 5 cooperate with each other, the extrusion die 7 is flush with the lower end surface of the die positioning block 5, and at the same time, the The slider 8 is in contact with the extrusion die 7; the cooperation of the guide post 9 and the guide sleeve hole 11 plays a guiding role. the

During the extrusion process, the position of the module 8 is shown in Figure 2, and the molding material can pass through the side-mounted strip-shaped slot connected to the cylindrical through hole provided on the slider 8. After the extrusion process, the push-pull module 8 Under the action of pulling force, the position shown in Figure 3 is reached, that is, the position of the cylindrical through hole and the central hole of the extrusion die 7 set on the slider 8 is concentric, and its diameter is slightly larger than that of the extrusion die 7. diameter, the workpiece can drop smoothly through the cylindrical through hole of the slider 8. After the extrusion die 7 falls, the push-pull module 8 is pushed to the position shown in Figure 2, and the extrusion of the remaining material is removed. Die 7 is placed in the cavity of die positioning block 5, then can realize cycle work. The cavity section of the extrusion die 7 can be a circle or other profile sections. the
