Description

Technical Field

[0001] The utility model relates to the technical field of die installation, in particular to a die positioning mechanism for an extruder. Background Art

[0002] When using the die in an extruder, a positioning plate is usually used as a device to assist in positioning and fixing the die. The positioning plate is usually installed at the bottom of the die, and the die is connected to the extruder or other equipment through the positioning plate. The main function of the positioning plate is to provide additional support and fixation to help ensure that the die maintains a stable position and accurate positioning during processing. Nowadays, mold positioning mostly uses pins to install and position the mold.

[0003] However, the existing mold positioning mechanism adopts a pin fixing method, which makes it difficult to disassemble it later. When the mold needs to be replaced, the original pins need to be destroyed, which not only causes material waste but also increases the difficulty of disassembly. In view of this, we propose a mold positioning mechanism for an extruder. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] The utility model can drive a clamping part to move by twisting the threaded rod in conjunction with the bearing seat, so that one clamping part approaches or moves away from the other clamping part. When one clamping part approaches the other clamping part, the auxiliary component located in the middle of the two clamping parts is fixed in position under the clamping action of the clamping parts. Otherwise, it is convenient for the staff to take out the auxiliary component from the positioning plate without damaging the auxiliary component, which is conducive to reuse. In addition, with the cooperation of the stabilizing ring and the clamping part, the purpose of reinforcing the position of the extrusion die is achieved, and the stability of the extrusion die during subsequent work is improved. At the same time, with the assistance of the positioning component, it is conducive to fixing the position of the two clamping parts, avoiding the extrusion die causing the positions of the two clamping parts during work, causing the auxiliary component to loosen.

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-3As shown, the die positioning mechanism for an extruder proposed by the utility model includes a positioning plate 1, the output end of a driving device 2 is connected to the top wall of the positioning plate 1, so as to drive the positioning plate 1 to move; an extrusion die 3 is located at the bottom of the positioning plate 1, and an auxiliary component 4 for assisting the installation of the extrusion die 3 is installed on the top wall of the extrusion die 3, and the auxiliary component 4 includes a vertical shaft 41, the bottom end of the vertical shaft 41 is fixedly connected to the top wall of the extrusion die 3, and two stabilizing rings 42 are fixedly sleeved on the outer ring surface of the vertical shaft 41; a plurality of clamping members 5 are divided into a group of two, and each group of clamping members 5 is arranged on the positioning plate 1. In multiple positioning holes, another clamping member 5 in each group is fixedly installed inside the positioning hole corresponding to the position, and semi-annular grooves are provided on the inner surface walls of the two clamping members 5. When the vertical axis 41 and the stabilizing ring 42 are located in the two clamping members 5, the two clamping members 5 in the combined state fix the position of the extrusion die 3 through the semi-annular groove and the stabilizing ring 42, so as to achieve the purpose of installing the extrusion die 3 on the positioning plate 1, and with the cooperation of the semi-annular groove and the stabilizing ring 42, it is beneficial to reinforce the position of the extrusion die 3 to avoid shaking of the extrusion die 3 during subsequent use.

[0021] Furthermore, an adjusting assembly 6 is provided on the back wall of a clamping member 5 for facilitating its position adjustment. The adjusting assembly 6 includes a vertical plate 61, which is fixedly mounted on the top wall of the positioning plate 1. A threaded rod 62 is arranged in a threaded hole provided on the vertical plate 61. One end of the threaded rod 62 passes through the threaded hole and is connected with the rotating end of the bearing seat 63. The bearing seat 63 is fixedly mounted on the back wall of a clamping member 5, so that it is convenient to drive a clamping member 5 to move by twisting the threaded rod 62, and it is convenient to release the limit of the auxiliary assembly 4 by the two clamping members 5, so that the staff can disassemble the extrusion die 3 without destroying the auxiliary assembly 4, and it can be reused at the same time to avoid waste of resources; a slideway is provided on the side wall of the positioning port, and a clamping member 5 is arranged in the slideway. Limiting grooves are symmetrically provided on the two side walls of the road, and sliding blocks are symmetrically arranged on the two side walls of a clamping member 5, and the two sliding blocks are respectively set in the limiting grooves corresponding to the positions, so as to facilitate the auxiliary threaded rod 62 to adjust the position of a clamping member 5, and under the cooperation of the limiting groove and the sliding block, a clamping member 5 is prevented from being separated from the positioning port, affecting the subsequent clamping and positioning of the auxiliary component 4; a T-shaped movable cavity is provided in the limiting groove provided on the side wall of the positioning port, and the limiting end of the T-shaped movable rod 7 is provided in the T-shaped movable cavity, and the connecting end of the T-shaped movable rod 7 is welded to the back wall of the clamping member 5.
