Abstract
An arc tapered tail end of a cross gate of a magnesium alloy die-casing die comprises a main gate of the magnesium alloy die-casing die. Two cross gates are connected to two sides of the main gate respectively and connected with a cavity of the magnesium alloy die-casing die through inner gates, products formed by die-casting are arranged in the cavity, and the tail ends of the two cross gates are provided with recoil storage caves respectively. The arc tapered tail end of the cross gate of the magnesium alloy die-casing die is characterized in that the tail end of each of the two cross gates is provided with an arc tapered extension section connected with the corresponding recoil storage section. During casting, the arc tapered extension sections change the high-speed recoil direction of metal liquid at the tail ends of the cross gates, the metal liquid with trapped gas and oxide impurities is prevented from entering the cavity through the inner gates due to high-speed recoil, and consequently defective castings are avoided, and the rejection rate of products is lowered.
Description
Technical field
The utility model relates to a kind of magnesium alloy pressure-casting mould cross gate arc taper end, belongs to the die casting field.
Background technology
At present; In the design of magnesium alloy pressure-casting mold runner; Conventional generally all adopt the straight section tail end to add storing cave structure in the design of crossing current road, its shortcoming is that the straight section tail end causes the metal materials flow to recoil at a high speed at tail end easily when casting, makes to have the molten metal of wrapping up in gas and oxide impurity and pass through ingate at cross gate; In the entering cavity, cause casting defect.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art; Provide a kind of cross gate tail end to adopt the arc conical design, change molten metal recoil direction, avoid causing casting defect; Reduce the product percent defective, the magnesium alloy pressure-casting mould cross gate arc taper end of enhancing productivity.
The technical scheme of the utility model magnesium alloy pressure-casting mould cross gate arc taper end is: comprise magnesium alloy pressure-casting mould master running channel; Main running channel both sides respectively connect a cross gate; Two cross gates connect magnesium alloy pressure-casting die cavity body through ingate, and the product of die cast is arranged in the cavity, and the tail end of two cross gates is provided with recoil storing cave separately; It is characterized in that described two cross gate tail ends are shaped on arc taper extension separately, arc taper extension connects recoil storing cave.
The magnesium alloy pressure-casting mould cross gate arc taper end of the utility model; Tail end at two cross gates is shaped on arc taper extension separately, and arc taper extension connects recoil storing cave, during casting; Arc taper extension has changed the high speed recoil direction of molten metal at the cross gate tail end; The molten metal of wrapping up in gas and oxide impurity that has of having avoided the metal materials flow to cause because of recoiling at a high speed gets in the cavity through ingate at cross gate, causes the foundry goods defectiveness, reduces the percent defective of product.
Description of drawings
Fig. 1 is the utility model magnesium alloy pressure-casting mould cross gate arc taper end structural representation.
The specific embodiment
It is as shown in Figure 1 that the utility model relates to a kind of magnesium alloy pressure-casting mould cross gate arc taper end; Comprise magnesium alloy pressure-casting mould master running channel 1, main running channel 1 both sides respectively connect 2, two cross gates of a cross gate 2 and connect magnesium alloy pressure-casting die cavity body through ingate 3; The product 4 that die cast is arranged in the cavity; The tail end of two cross gates 2 is provided with recoil storing cave 5 separately, it is characterized in that described two cross gate 2 tail ends are shaped on arc taper extension 6 separately, and arc taper extension 6 connects recoil storing cave 5.This programme is shaped on arc taper extension 6 separately at the tail end of two cross gates 2; Arc taper extension 6 connects recoil storing cave 5; During casting, arc taper extension 6 has changed the high speed recoil direction of molten metal at cross gate 2 tail ends, and the molten metal of wrapping up in gas and oxide impurity that has of having avoided the metal materials flow to cause because of recoiling at a high speed gets in the cavity through ingate at cross gate; Cause the foundry goods defectiveness, reduce the percent defective of product.
