[Industrial applications]

 TECHNICAL FIELD The present invention relates to a casting frame fitting machine for fitting an upper frame and a lower frame in which a molded mold is built.

[0002]

[Prior art]

 The upper and lower frames that house the molded mold are often transported by roller conveyors. When the mold reaches the position of the flask matching machine, the upper mold is first held upward by the upper frame gripping tool. Then, when the lower die reaches below the upper die, the upper die descends and the pins of the lower frame and the pin holes of the upper frame are fitted to each other to complete the casting frame alignment.

[0003]

[Problems to be solved by the device]

 However, the lower surface of the lower frame is often damaged, and is not held perfectly horizontally on the roller conveyor. Therefore, the pins of the lower frame and the pin holes of the upper frame cannot be fitted smoothly, and the gap between the pins and the pin holes must be increased. Therefore, it is a major factor that hinders the improvement of dimensional accuracy such as crossing of cast products, and the development of new technology has been strongly desired in the industry.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a framing machine that can bring about a remarkable effect in improving the quality of cast products.

[0005]

[Means for Solving the Problems]

 The casting frame matching machine of the present invention comprises an upper frame gripping tool connected to an opening / closing cylinder above a base on which a roller conveyor for alternately transporting an upper mold and a lower mold is arranged. It is characterized in that it has a vertical flask holding rod mounted on an elevator under the roller conveyor, and the tip of the flask holding rod is conical or truncated conical. It is more effective to provide a conical recess on the lower surface of the flask contacting the flask holding rod.

【Example】

 Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a front view of the flask matching machine, and FIG. 2 is a partial sectional side view of the flask matching machine.

A roller conveyor 1 for alternately arranging and transporting an upper mold and a lower mold is provided so as to extend over the base 2. An upper frame holding tool 4 connected to an opening / closing cylinder 3 is provided above the base 2. A vertical flask holding rod 6 mounted on the elevator 5 is provided below the. Further, the tip 7 of the casting frame holding rod 6 is formed into a conical shape or a truncated cone shape, and if a conical concave portion 8 is provided on the lower surface of the casting frame with which the casting frame holding rod 6 contacts, an upper frame 9 Further, the position and the levelness of the lower frame 10 can be stably and easily held. Reference numeral 11 is a pin, 12 is a pin hole, and 13 is a stopper.

Next, the operation and effect of the above structure will be described. First, when the upper frame 9 is conveyed over the roller 14 of the roller conveyor 1, the cylinder 15 operates and the stopper 13 stops the upper frame 9 at a predetermined position. Here, the elevator 5 rises and the upper frame 9 is pushed upward by the flask holding rod 6, the opening / closing cylinder 3 operates, and the upper frame holding tool 4 holds the upper frame 9. The casting frame holding rod 6 descends together with the elevator 5 and returns to its original position.

Next, when the cylinder 15 operates and the stopper 13 is opened, the lower frame 10 is conveyed over the roller 14 of the roller conveyor 1. The cylinder 15 operates again and the stopper 13 stops the lower frame 10 at a predetermined position. Here, the elevator 5 rises and the lower frame 10 is pushed upward by the casting frame holding rod 6, so that the pin 11 of the lower frame 10 and the pin hole 12 of the upper frame 9 are fitted to each other. In this state, the opening / closing cylinder 3 is operated, the upper frame gripping tool 4 is disengaged from the upper frame 9, the casting frame holding rod 6 is lowered, and the upper frame 9 and the lower frame 10 are placed on the rollers 14 of the roller conveyor 1. It At this time, if the tip 7 of the flask holding rod 6 is formed into a conical shape or a truncated cone, and if a conical concave portion 8 is provided on the lower surface of the flask with which the flask holding rod 6 contacts, the upper frame It is possible to stably and easily hold the positions of 9 and the lower frame 10 and the levelness thereof. In this embodiment, the scissor lift (trade name) was used as the elevator, but the present invention is not limited to this, and it is needless to say that the same purpose can be achieved by using a general fluid pressure cylinder.
