Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of squeeze casting molds, and more specifically, to a squeeze casting gating system and a mold for a torsion-resistant tie rod skeleton. Background Art
[0002] The main function of the torsion-resistant tie rod is to connect the subframe and the engine assembly, and at the same time provide a certain vibration isolation performance. The torsion-resistant tie rod includes a skeleton, a large bushing and a small bushing, wherein the skeleton serves as a supporting body and bears large torques and tensile moments. At present, the production and manufacturing methods of automotive torsion-resistant tie rod skeletons in China are as follows: 1. After stamping the steel plate, the installation points are welded by CO2 shielded welding, and additional electrophoretic rust prevention treatment is required; 2. Extruded aluminum profiles are used, and after T6 heat treatment, the finished product of the tie rod skeleton is obtained by machining; 3. High-pressure casting is carried out with aluminum alloy materials, and then the finished product of the torsion-resistant tie rod skeleton is obtained by machining. However, the above three methods have defects.
[0003] Among them, 1. The disadvantages and reasons for forming the torsion-resistant tie rod skeleton by stamping the steel plate: The steel plate is relatively heavy, resulting in a relatively heavy vehicle, high fuel consumption or reduced cruising range of new energy vehicles. Moreover, additional welding jigs need to be designed to weld the fixed-point brackets by CO2 gas shielded welding. Toxic and harmful fumes will be generated during the welding process, causing great environmental pollution, complex processes, and the surface needs to be treated with electrophoretic rust prevention after welding, which is not friendly to the environment. The welds are prone to rusting and cracking, affecting the durability and reliability of the vehicle; 2. The disadvantages and reasons for forming the torsion-resistant tie rod skeleton by using extruded aluminum profiles: After using the extruded aluminum profiles, the machining allowance is very large, the material utilization rate is very low, and there is a great waste. The machining cost is high, resulting in an increase in the unit price of parts by more than a dozen yuan, affecting the cost performance of hybrid vehicles; 3. The disadvantages and reasons for forming by using the aluminum alloy high-pressure casting process: During the high-pressure die casting process of aluminum alloy, the filling is not stable and gas is easily involved. Porosities, shrinkage cavities, pinholes and other defects often appear inside the casting. Fatigue fractures are likely to occur during the vehicle's acceleration, deceleration and braking durability tests. Moreover, the die-cast aluminum tie rod cannot be subjected to T6 heat treatment to improve strength and surface hardness, and the material strength and surface hardness cannot meet the requirements of the large-load hybrid vehicle working conditions, thus affecting the product durability and reliability. Summary of the Utility Model
[0004] To solve the above problems, the utility model proposes a squeeze casting gating system and a mold for a torsion-resistant tie rod skeleton, which can produce a torsion-resistant tie rod skeleton under the conditions of low material and energy consumption, and the produced torsion-resistant tie rod skeleton can meet the mechanical property requirements of the vehicle for parts and meet the high reliability requirements of automotive parts.
[0005] To achieve the above object, a squeeze casting gating system for a torsion-resistant tie rod skeleton includes a core assembly. A cavity adapted to the torsion-resistant tie rod skeleton is formed inside the core assembly. At least one runner communicating with the cavity is provided in the core assembly. One end of the runner is correspondingly arranged at the rod body of the torsion-resistant tie rod skeleton, and the other end of the runner extends towards the outer wall of the core assembly and communicates with a gate provided on one side of the core assembly. An exhaust structure is communicated with the periphery of the cavity.
[0006] In this technical solution, since the volume of the molten metal will become smaller when it cools and solidifies, if enough molten metal cannot be obtained to supplement the space generated by shrinkage, shrinkage cavities and porosity will occur in the torsion-resistant tie rod skeleton. The molten metal flows in through the gate on the outer wall of the cavity assembly and then enters the cavity through the runner. The rod body of the torsion-resistant tie rod skeleton is a thick-wall part. The runner is arranged at the thick-wall part of the torsion-resistant tie rod skeleton to increase the flow rate of the molten metal, so that the molten metal can fill the cavity faster. After the molten metal fills the cavity, the punch extrudes the molten metal in the gate for feeding to reduce the porosity of the torsion-resistant tie rod skeleton. The exhaust structure is used for exhausting gas to reduce defects such as air holes and shrinkage cavities. The torsion-resistant tie rod skeleton produced by this squeeze casting gating system not only has good quality, and the shrinkage cavities and air holes can meet the product use requirements, but also can reduce production costs.
[0007] As a preferred solution, two runners are communicated with the cavity. One end of one runner is correspondingly arranged at the rod body of the torsion-resistant tie rod skeleton, and one end of the other runner is correspondingly arranged at the large bushing mounting hole of the torsion-resistant tie rod skeleton. The other ends of the two runners converge and communicate with the gate. A gate sleeve corresponding to the position of the gate is provided on one side of the core assembly. Since the filling stroke of the large bushing is relatively long, arranging a runner at its corresponding position can make the filling time of the molten metal shorter. The rod body of the torsion-resistant tie rod skeleton is the center of gravity and the part with the largest wall thickness value, which can increase the flow rate of the molten metal. The gate sleeve is used to cooperate with the punch for extrusion feeding.
[0008] As a preferred solution, the large bushing mounting hole and the small bushing mounting hole of the torsion-resistant tie rod skeleton are thin-wall parts, and it is easier to accumulate air bubbles at the thin-wall parts. To enable the cavity to exhaust gas smoothly, the exhaust structure includes a plurality of slag pocket cavities communicated with the cavity. The plurality of slag pocket cavities respectively correspond to the positions of the large bushing mounting hole and the small bushing mounting hole of the torsion-resistant tie rod skeleton. The slag pocket cavity can collect the skin slag oxidized by the molten metal and can also exhaust gas. The exhaust block can quickly exhaust the gas in the cavity, preventing the gas from having a negative impact on the torsion-resistant tie rod skeleton, such as defects like air holes and bubbles, thereby improving the production quality.
[0009] As a preferred solution, an exhaust block communicating with the slag pocket cavity is provided on one side of the core assembly. The slag pocket cavity can guide gas into the exhaust block to quickly exhaust the gas in the cavity, preventing the gas from having a negative impact on the torsion-resistant tie rod skeleton, such as defects like pores and bubbles, thereby improving the production quality.
[0010] As a preferred solution, in order to uniformly cool the molten metal in a timely manner after filling, a cooling water channel is provided inside the core assembly. The cooling water channel is arranged beside the gate and the runner. One end of the cooling water channel extends outwards towards the outer wall of the core assembly. Since the torsion-resistant tie rod skeleton is a small casting, in order to ensure the filling rate, the gate is thicker than the cavity. Therefore, without the intervention of cooling equipment, this position solidifies last. For this reason, the cooling water channel is arranged beside the gate to accelerate cooling, so as to reduce the solidification time difference of each part of the torsion-resistant tie rod skeleton, thereby ensuring the product quality.
[0011] As a preferred solution, the core assembly includes an upper core and a lower core. The upper core and the lower core are buckled together to form the cavity. The gate, the runner, and the exhaust structure are respectively arranged at the connection between the upper core and the lower core. The upper mold and the lower mold respectively correspond to the forming of the upper half and the lower half of the torsion-resistant tie rod skeleton.
[0012] As a preferred solution, in order to ensure the precise alignment of the upper core and the lower core, first positioning parts are respectively provided at the four corners of the bottom of the upper core, and second positioning parts matching with the first positioning parts are respectively provided around the bottom of the lower core. Each of the first positioning parts is respectively in contact with each of the second positioning parts, which can prevent loosening between the upper core and the lower core and affect the product quality.
[0013] As a preferred solution, a core-pulling mechanism is provided on one side of the core assembly. The core-pulling mechanism includes a driving device, a guide rail, and a sliding structure. The sliding structure is slidably connected to the guide rail. A guide hole communicating with the cavity is provided on one side of the core assembly. One end of the sliding structure extends into the guide hole and is placed in the small bushing mounting hole of the torsion-resistant tie rod skeleton. The driving end of the driving device is connected to the other end of the sliding structure. In the demolding stage, the driving end of the first driving structure drives the sliding structure to perform linear sliding in the guide hole along the guide rail, so that one end of the sliding structure disengages from the small bushing mounting hole of the torsion-resistant tie rod skeleton.
[0014] As a preferred solution, in order to facilitate the removal of the rough blank of the torsion-resistant tie rod skeleton during mold opening, a plurality of ejector holes are provided in the lower core. The ejector holes vertically penetrate through the cavity and the bottom of the lower core, and the rough blank of the torsion-resistant tie rod skeleton on the lower core can be ejected by pushing.
[0015] A mold includes the above-mentioned torsion-resistant tie-bar skeleton squeeze casting gating system, and further includes an upper mold assembly, a lower mold assembly and a guiding assembly. The upper mold assembly is fixed to the top of the core assembly, the lower mold assembly is fixed to the bottom of the core assembly, one end of the guiding assembly is fixed to the lower mold assembly, and the other end of the guiding assembly is sleeved with the upper mold assembly.
[0016] In this technical solution, the upper mold assembly and the lower mold assembly drive the core assembly to perform mold opening and closing actions under the guidance of the guiding assembly.
[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0018] 1. The torsion-resistant tie-bar skeleton squeeze casting gating system of the present utility model can replace the traditional production method of the torsion-resistant tie-bar skeleton, complete the squeeze casting forming, with high utilization rate of raw materials, reduced energy consumption and lower production cost.
[0019] 2. By extruding the molten metal at the gate with a punch, feeding can be achieved to reduce the shrinkage porosity of the torsion-resistant tie-bar skeleton. The design of the exhaust structure position reduces defects such as air holes and shrinkage cavities in the torsion-resistant tie-bar skeleton, ensuring the production quality of the torsion-resistant tie-bar skeleton to meet the mechanical property requirements of the vehicle.
[0020] 3. The design of the runner position can make the molten metal quickly and evenly fill the cavity, improving the production efficiency while ensuring the production quality. Description of the Drawings

[0035] In this embodiment, the core assembly 1 includes an upper die core 11 and a lower die core 12. The upper die core 11 and the lower die core 12 are buckled to form the cavity 13. The gate 14, the runner 15, and the exhaust structure 16 are respectively arranged at the connection between the upper die core 11 and the lower die core 12.

The four first positioning parts 111 are respectively arranged at the four corners of the bottom of the upper die core 11, and the four second positioning parts 121 are respectively arranged at the four corners of the top of the lower die core 12.

[0036] Specifically, two runners 15 are communicated with the cavity 13. One end of one of the runners 15 is correspondingly arranged at the rod body 91 of the torsion-resistant tie rod skeleton 9, and one end of the other runner 15 is correspondingly arranged at the large bushing mounting hole 92 of the torsion-resistant tie rod skeleton 9.

By arranging the cooling water channel 4 beside this position for cooling, the solidification time of the molten metal at this place can be reduced, so that the solidification time difference of each part of the torsion-resistant tie rod skeleton 9 is narrowed, making the stress of the torsion-resistant tie rod skeleton 9 product small, not prone to thermal cracking, saving materials, and the cooling of each part is uniform, with small thermal stress, not prone to deformation and cracking.
