Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pouring equipment, and specifically relates to the pouring equipment of automobile engine support. BACKGROUND

[0002] The engine support is an important supporting component of the automobile engine, mainly serving to fix the engine and transfer the torque. The engine support in the existing technology of a car generally adopts steel material. Since the steel casting is heavy, it affects the consumption of gasoline. Meanwhile, with the gradual improvement of safety requirements, the engine support also needs to bear part of the energy absorption during the vehicle collision.

[0003] In the production process of the existing engine support, the molding material is sent into the die casting mold through the mold gate to realize molding. Since the engine support is generally made of metal material, the molten material will transfer heat to the gate bush when flowing through the equipment gate bush during the pouring process. The gate bush is continuously heated by the high-temperature material in this process, and then the gate bush is prone to overheating and cracking. The service life of the gate bush is short, and it needs to be replaced frequently, which increases the overall production cost of the support.

[0004] Therefore, the utility model provides a pouring equipment for an automobile engine support. UTILITY MODEL CONTENTS

[0010] Furthermore, the main body of the sprue bushing is vertically arranged in a cylindrical shape and is fixedly connected by a positioning plate and a guide seat. The main body of the first heat-conducting sleeve is set as a conical hollow copper sleeve, with its upper and lower ends sealed to the main body of the sprue bushing.

[0011] The heat dissipation groove is vertically opened in a trapezoidal shape along the main body of the first heat-conducting sleeve, and the top of the main body of the first heat-conducting sleeve is provided with pipe interfaces for the corresponding inlet pipe and circulation pipe.

[0012] Furthermore, the inner surface of the first heat-conducting sleeve body is also provided with copper heat-conducting strips distributed in a spiral shape.

[0013] Furthermore, the second heat-conducting sleeve structure includes a second heat-conducting sleeve body and an inlet pipe and a circulation pipe connected thereto. The second heat-conducting sleeve body is hollow and is sealed to the main gating system.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] See Figures 1-4 As shown, the gating equipment for an automotive engine bracket includes a die-casting zone 1 and its matching riser 2 and venting groove 3. A gating sleeve structure 5 is connected to the outer end of the die-casting zone 1. An outer mounting bracket 4 is fixedly connected between the gating sleeve structure 5 and the die-casting zone 1. The gating sleeve structure 5 includes a guide seat 6 and a gating sleeve body 7 connected sequentially from bottom to top. An mounting collar 8 is fixedly sleeved between the guide seat 6 and the gating sleeve body 7. A main runner 12 is fixedly connected to the top of the gating sleeve body 7. A second heat-conducting sleeve structure 11 and a first heat-conducting sleeve body 10 are respectively sleeved at the upper and lower ends of the gating sleeve body 7. A heat dissipation groove 16 is fixedly provided on the surface of the first heat-conducting sleeve body 10. Positioning plates 9 are fixedly connected to both ends of the bottom of the first heat-conducting sleeve body 10. The positioning plates 9 and the guide seat 6 are connected by screws. The external cooling water source first enters the second heat-conducting sleeve body 13 through the inlet pipe 14. After cooling the lower section of the main runner 12 through the second heat-conducting sleeve body 13, it enters the first heat-conducting sleeve body 10 to cool the sprue sleeve body 7. Then it is discharged outward through the circulation pipe 15. This process can be circulated in conjunction with the external cooling supply device. At the same time, during this cooling process, the upper section of the main runner 12 is the material inlet interface position with the die-casting area 1. Therefore, the second heat-conducting sleeve body 13 located at the lower section of the main runner 12 can avoid over-cooling at the material inlet interface position, ensure the temperature of the material inlet interface position, and prevent the main runner 12 and the material inlet interface position of the die-casting area 1 from breaking during the subsequent mold opening process. At the same time, it can ensure the stability of the material inlet and the molding efficiency of the subsequent material in the die-casting area 1.

[0027] In this embodiment of the utility model, a cylindrical material guiding cavity is formed at the center of the surface of the material guide seat 6, which is connected to the main body of the sprue sleeve 7. The material guide seat 6 is fixedly fitted to the main body of the sprue sleeve 7 by the mounting collar 8. The main body of the sprue sleeve 7 is set vertically in a cylindrical shape and is fixedly connected to the material guide seat 6 by the positioning plate 9. The first heat-conducting sleeve body 10 is set as a conical hollow copper sleeve, and its upper and lower ends are sealed to the main body of the sprue sleeve 7. The heat dissipation groove 16 is set vertically in a trapezoidal shape along the first heat-conducting sleeve body 10. At the same time, the top of the first heat-conducting sleeve body 10 is provided with pipe interfaces corresponding to the inlet pipe 14 and the circulation pipe 15. The inner surface of the first heat-conducting sleeve body 10 is also provided with copper heat-conducting strips distributed in a spiral shape. The heat dissipation effect of the sprue sleeve body 7 is achieved by the first heat-conducting sleeve body 10 in conjunction with the heat dissipation groove 16 on its surface.

[0028] After the external cooling water source enters the first heat-conducting jacket body 10, the heat received by the gate sleeve body 7 can be quickly dissipated and discharged outward under the action of the heat-conducting strip on its inner side and the heat dissipation groove 16 on its outer side, so as to achieve the cooling effect, avoid the gate sleeve body 7 from cracking due to severe heat, and ensure its service life during the gate process. After the cooling water source enters the first heat-conducting jacket body 10, the heat-conducting strip set on its inner side can effectively make the cooling water source swirling, with high heat conduction efficiency, which can cool the gate position of the gate sleeve body 7 as soon as possible.

[0029] The second heat-conducting jacket structure 11 includes a second heat-conducting jacket body 13 and an inlet pipe 14 and a circulation pipe 15 connected thereto. The second heat-conducting jacket body 13 is hollow and is sealed to the main gating 12. The inlet pipe 14 and the circulation pipe 15 each have two vertically arranged pipe sections, which are respectively connected to the upper and lower ends of the second heat-conducting jacket body 13. At the same time, the inlet pipe 14 and the circulation pipe 15 located at the lower end of the second heat-conducting jacket body 13 are connected to the top of the first heat-conducting jacket body 10. The inlet pipe 14 and the circulation pipe 15 achieve the effect of introducing and discharging cooling water, and the second heat-conducting jacket body 13 achieves the effect of cooling the lower section of the main gating 12.

[0030] The outer ends of the inlet pipe 14 and the circulation pipe 15 are connected to a cooling supply mechanism and a pump body mechanism.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
