Problems solved by technology

When a large mold needs to be used, since the distance between the tie rods is greater than the size of the mold, the large mold cannot be hoisted into the clamping mechanism from above smoothly. If a large mold is to be loaded, the tie rods must be removed to avoid the mold. It is very time-consuming and laborious, and it is very inconvenient

Embodiment Construction

[0020] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0021] refer to Figure 1-2 :

[0022] An automatic pull-type tie rod 2 of a two-plate mold clamping mechanism, the rear end of the tie rod 2 is movably inserted into the rod hole provided on the outer side of the top of the fixed formwork 1, and the front end points to the movable formwork.

[0023] The outer hole end of the rod hole is fixedly equipped with an end cover 11, and the end cover 11 is rotatably provided with a tie rod nut 3, and the outside of the tie rod nut 3 is provided with a nut gland 4 for preventing its internal and external displacement.

[0024] The pull rod 2 is screwed into the pull rod nut 3 through the external thread set at its rear end, and its rear end passes through the pull rod nut 3 and the nut gland 4 and is fixedly connected with the slider 6, and the slider 6 is slidably connected to the fixed On the horizontal gu...

Abstract

The invention relates to an automatic pull-out type pull rod of a two-plate type clamping mechanism. According to the technical scheme, the rear end of the pull rod is movably inserted into a rod holeformed in a fixed die plate, the front end of the pull rod is pointed to a movable die plate, the rear end of the pull rod is screwed into a pull rod nut through an outer screw thread, the pull rod nut is rotatably connected to the fixed die plate and is driven by a driving assembly arranged on the fixed die plate to rotate, so that the pull rod is driven to move inwards and outwards in a reciprocating mode relative to the fixed die plate along a transverse guide rod device arranged on the outer end surface of the fixed die plate. According to the clamping mechanism, the mold adaptability andthe mold mounting convenience of the clamping mechanism can be improved.

Description

technical field [0001] The invention relates to a two-plate mold clamping mechanism, in particular to a tie rod connection structure of the two-plate mold clamping mechanism. Background technique [0002] At present, in the plastic processing, metal die-casting and rubber processing industries, most of the clamping mechanisms used in injection molding equipment and die-casting equipment are two-platen, referred to as the second-platen machine. The two-plate mold clamping mechanism has been widely used because of its simple and compact structure and ease of use. The two-plate mold clamping mechanism generally includes a movable template and a fixed template. The fixed template is equipped with multiple pairs of tie rods in pairs. The movable template is driven by the locking cylinder to reciprocate laterally relative to the fixed template, and the movable template moves closer to the fixed template. During the process, the front end of the pull rod can be locked by the brake...
