A rack guide mechanism, such as a 'slide foot adjusting mechanism of an injection molding machine' disclosed by the application number 201320147113.5, in particular discloses a slide foot adjusting mechanism for realizing the forward and lateral support and guide of a movable template. This structure has the following problems: (1) the adjustment between the lateral sliding foot and the lateral guide rail can be realized only by increasing or decreasing the adjusting gasket, and the adjustment range of the lateral sliding foot is smaller by the adjustment mode; (2) the sliding foot pressing plate is positioned at the inner side below the movable template, so that the adjustment operation is difficult and the rapid adjustment is not facilitated; (3) the structure of the side guide rail is not mentioned in the guide structure, and the problem that whether the structure of the side guide rail can ensure the integral guide performance and the manufacturing and processing cost is not considered.

A side guide mechanism of a rack, namely a conventional rack guide structure of the current injection molding machine, is provided with a guide mechanism for preventing a movable template from deflecting along a side direction vertical to a pull rod direction besides forward support and guide, wherein a first guide plate in the guide mechanism is generally fixed on a machine base in a welding mode, and a guide slideway is machined. This approach has the following disadvantages: (1) four runner guide slideways, namely two forward slideways and two lateral slideways, need to be arranged on the rack along the length direction of the pull rod, and in order to ensure the guide precision, the forward slideways and the lateral slideways need to ensure higher form and position tolerance, so that the machining of the structure needs to be carried out in a numerical control machining center, the machining cost is very high, and the efficiency is low; (2) the base of the injection molding machine is generally of a welded structure, and after welding, the base can deform greatly, so that even if the base is subjected to aging or stress relief treatment, the problem of deformation is generally existed in subsequent use, and the form and position tolerance of the forward and lateral slide ways is more difficult to guarantee, so that the guide precision is deteriorated.

4. The linear rolling guide rail is used for guiding, and the guide structure is limited by the influences of low quality of domestic steel, poor aging treatment effect, poor machining precision and high cost of a high-bearing linear rail, and is difficult to achieve an ideal guide effect in practice.
