Description

Technical Field

[0001] The utility model belongs to the field of machinery, and in particular relates to a connecting mechanism which does not affect the up-down and forward-backward movement of a device. Background Art

[0002] In the casting field, the flask molding machine is widely used and can meet the requirements of larger castings and some special castings. The flask molding machine needs two sets of upper and lower mold frames to meet the requirements of a complete set of sand casting. The upper and lower mold plates need to be alternately molded during flask molding, so the mold plates need to be replaced and need to move up and down with the lifting workbench to meet the molding requirements. In order to solve the problem that the upper and lower mold frames can move left and right together under the drive of the motor when moving left and right and up and down. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides a connecting mechanism with a simple structure that does not affect the up-down and forward-backward movement of the device.

[0004] The technical solution adopted by the utility model is a connecting mechanism that does not affect the up and down, front and back movement of the device, including an upper plate frame, an upper hook, a limit block, a lower hook, and a lower plate frame; the upper plate frame and the upper hook are fixed by screws, the limit block with screws is fixed on the upper hook, the lower plate frame and the lower hook are fixed by screws, the limit block is fixed on the lower hook, and the upper and lower hooks are in contact through the limit block; the upper hook and the lower hook are both 45-degree U-shaped inclined surface structures.

[0005] The utility model provides a connection mechanism which does not affect the up and down front and back movement of the device, has a simple structure and solves the technical problem that the upper and lower molded plate frames can move forward and backward together under the drive of a motor when moving forward and backward and up and down.

[0009] The specific implementation methods, structures, features and functions of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0010] The technical solution adopted by the utility model is a connection mechanism that does not affect the up and down forward and backward movement of the device, including an upper plate frame, an upper hook, a limit block, a lower hook, and a lower plate frame; the upper plate frame is fixed to the upper hook by screws, the limit block with threads is fixed to the upper hook, the lower plate frame is fixed to the lower hook by screws, the limit block is fixed to the lower hook, and the upper and lower hooks are in contact through the limit block. Both the upper hook and the lower hook are 45-degree U-shaped inclined structures.

[0011] The working principle of the utility model is:

[0012] When the template frame moves left and right: the upper hook hand 2 and the lower hook hand 4 hook the upper and lower template frames and move left and right together under the drive of the driving cylinder.

[0013] When the template frame moves up and down: the upper template frame is lifted upward by the lifting workbench, and the hooks of the upper and lower template frames are disengaged. After the modeling is completed, the lifting workbench drives the upper template frame to move downward until the upper template frame drops into place and hooks with the hooks of the lower template frame. Only then can it move left and right to replace the template.

[0014] The utility model provides a connection mechanism which does not affect the up and down front and back movement of the device, has a simple structure and solves the technical problem that the upper and lower molded plate frames can move forward and backward together under the drive of a motor when moving forward and backward and up and down.

[0015] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should fall within the scope of the patent coverage of the utility model.
