The condition of the steering gear housing directly affects the performance and safety of the steering system, making it extremely important. It also requires good airtightness. However, due to its complex structure, sophisticated molds are needed for support. Steering gear molds typically require 6-8 sliders in the design to cast a complete product, including many double-angle sliders and inclined core-pulling structures, placing high demands on the mold frame's structure.

This product is a 1600T six-slider steering gear mold frame, including two double-angle inclined sliders and one inclined core-pulling mechanism. The processing difficulties of this mold frame are as follows:

For the double-angle inclined slider frame part, to ensure smooth processing, our company has developed an auxiliary worktable in combination with our four-axis horizontal boring machine.

To minimize the deformation coefficient of the auxiliary worktable, we specifically use QT500 casting material and perform secondary tempering.

To ensure the portable use of the worktable, we have densely drilled M20 threaded holes on the worktable for easy clamping with pressure plates, while ensuring the angular accuracy of the worktable.

First, the auxiliary worktable is used to pad an angle, and then the B-axis of the boring machine is rotated to ensure the positional accuracy of the double-angle core-pulling structure.

The design of the auxiliary worktable has significantly reduced the processing difficulty for operators when machining complex-angle core-pulling frames, reduced the cost of five-axis machining, and enhanced the competitiveness in processing mold frames with similar difficulties to steering gear housings.
