Device for Finding the Cooling Point of the Hot Section of the Wheel Hub Casting Side Mold and Its Application

Abstract

The invention relates to an aluminum alloy hub gravity casting side die hot spot cooling point seeking device. According to positions of cooling holes required by a side die and a bridging principle, the point seeking device is simple in structure and convenient to operate, and by a square groove design of a main rod 8, vertical movement of a vertical connection rod is realized, and adaptability to different hub dies is realized. Left and right locking blocks 15 adjustable in distance are further arranged at two ends of a right-angle gauge respectively, and owing to threads of the locking blocks, stability of the device in a point seeking process is improved, and simplicity and convenience in operation are further improved. The problem of difficulty in point seeking is solved, procedures are simplified while hole position precision is guaranteed, and operation efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of aluminum alloy wheel hub gravity casting molds, in particular to a side mold point finding device in the aluminum alloy wheel hub gravity casting mold and its application. Background technique [0002] For wheel hub gravity casting side molds, it is very important to find the cooling point of the hot joint, and the deviation of the cooling point will lead to the scrapping of the wheel hub product. In the traditional mold processing process, the existing process of finding the cooling point of the hot section mainly adopts the following method: use the chord length between the holes to find the point from the cavity wall, use a hand electric drill on the front to drill a Φ5 through hole, and Through the back cavity, and then plug the hole of Φ5 welding. This method needs to drill holes on the mold, which will have a serious impact on the service life of the mold; at the same time, cracks will occur around the Φ5 ho...

Problems solved by technology

This method needs to drill holes on the mold, which will have a serious impact on the service life of the mold; at the same time, cracks will occur around the Φ5 hole, and it will be inconvenient for processing operations. The position of the front of the mold is guaranteed, but the position of the back cavity is difficult to guarantee. Completely mastered by the operator's technology, with strong randomness

Another method is to implement it on a small end milling machine. With the help of the dividing head of the small end milling machine, align the middle and side molds and punch holes according to the angle. The size of the side mold cannot be applied to the use of large molds, and the production efficiency is low

[0003] It can be seen that the lack of a simple and easy-to-operate aluminum alloy wheel hub gravity casting side mold cooling point finding device for the existing technology, and at the same time, in order to achieve accurate point finding and meet the needs of industrial production, it belongs to the wheel hub mold processing field and needs to be solved urgently The problem
