Problems solved by technology

However, the vertical line pouring system used by most manufacturers is relatively simple at present, and its slag retaining ability is poor, and the yield rate is low. In addition, multiple cavities cannot be guaranteed to be filled at the same time during pouring, so the temperature difference of the same mold product is large , the produc

Embodiment 1

[0028] Such as figure 1 As shown, the bracket casting hybrid pouring device of the present invention includes a template 1, a sprue cup 2 is arranged on the top of the template 1, and a plurality of bracket patterns 6 are arranged on the template 1, and the template 1 and the bracket patterns 6 pass through the horizontal The runners are connected, and the runners are divided into horizontal runners 3 and vertical runners 9. The horizontal runner 3 is a high trapezoidal section, which has a good slag avoidance effect, reduces product slag holes, and improves product qualification. The vertical runner 9 is a standard trapezoidal cross-section, which has good transmission capacity, improves the filling capacity of molten iron, and can be poured at a lower temperature. The support pattern 6 is externally connected to the riser 4, and the riser 4 is connected to the support pattern 6 is connected through the riser neck 5, the riser neck 5 can also serve as an ingate, the riser 4 i...

Abstract

The invention relates to the technical field of manufacturing castings and particularly relates to a mixing-type pouring device and a casting technology for support castings. The mixing-type pouring device includes a mould plate, a sprue cup arranged on the upper part of the mould plate and a plurality of support molds arranged on the mould plate, wherein the mould plate is communicated with the support molds through a transversal pouring gate. The transversal pouring gate includes a horizontal transversal pouring gate and a vertical transversal pouring gate. A plurality of risers are externally connected to the support molds and are connected to the support molds through riser necks. The horizontal transversal pouring gate is externally connected to the risers and is communicated with the risers through connecting members. The mixing-type pouring device has good slag avoiding effect and has high casting qualification rate, achieves stable and smooth mold filling, reduces sand blasting defect, and increases the qualification rate of castings.

Description

technical field [0001] The invention relates to the technical field of casting manufacturing, in particular to a mixed pouring device for bracket castings and a casting process for bracket castings. Background technique [0002] Bracket parts are a very common product with small dimensions and weight. During the product process design, there are eight cavities in one mold, and the DISA vertical line is used for production, so the efficiency is high. The production efficiency of this product is as high as 2500 pieces / hour. However, the vertical line pouring system used by most manufacturers is relatively simple at present, and its slag retaining ability is poor, and the yield rate is low. In addition, multiple cavities cannot be guaranteed to be filled at the same time during pouring, so the temperature difference of the same mold product is large , the product performance varies greatly, and the consistency is poor. It is difficult to meet the requirement that the hardness ...
