Description

Technical Field

[0001] This utility model relates to the field of bus parts processing, specifically a one-piece molding mold for a bus rear suspension lateral thrust rod support. Background Art

[0002] The working principle of the bus transverse thrust rod support mold is mainly to process the raw material into a transverse thrust rod support that meets the requirements through a specific structure and process; the mold is installed on the corresponding production equipment (die-casting machine), and then the mold closing operation is performed; during mold closing, the upper and lower molds or left and right molds of the mold are tightly closed through mechanical movement to form a closed cavity to accommodate the raw material; according to the material requirements of the support, the molten metal is injected into the mold cavity through the injection mechanism of the die-casting machine; the raw material undergoes cooling, solidification, and solidification processes in the mold cavity, gradually forming the shape of the bus transverse thrust rod support; after the product is formed, the mold opening operation is performed, and the upper and lower molds or left and right molds of the mold separate, allowing the formed support to be removed from the mold;

[0003] Regarding the thrust rod support mold, a search revealed a thrust rod support mold with publication number CN210966858U that can reduce the assembly process. The document states that when the upper and lower molds are combined, the upper and lower cavities of the gating system can form a complete gating system cavity; the upper and lower cavities of the support can form a complete thrust rod support cavity.

[0004] Although the aforementioned mold can be used to form the lateral thrust rod support of the rear suspension of a bus, the product is processed when the upper and lower molds are joined. When it is time to demold, the mold needs to be cooled before demolding. The current cooling method cannot cool the upper and lower molds simultaneously, resulting in uneven cooling of the product inside the upper and lower molds, which affects the molding quality of the product and the molding efficiency of the mold. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated molding die for the lateral thrust rod support of a bus rear suspension, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, a one-piece molding mold for a passenger vehicle rear suspension lateral thrust rod support is provided, comprising an upper mold, a lower mold mounted on the bottom of the upper mold, and a lower cooling structure mounted on the bottom of the lower mold. Simultaneously, an upper cooling structure is mounted on the surface of the upper mold. The upper cooling structure includes cooling channels formed on the surface shell of the upper mold, and multiple sets of flow-blocking plates are uniformly fixed inside the cooling channels, forming a flow channel between the flow-blocking plates. An inlet pipe is fixedly mounted on one end of the upper mold, and an outlet pipe is mounted on the upper side of the inlet pipe.

[0007] Preferably, the lower cooling structure and the upper cooling structure have the same composition, and the lower cooling structure is disposed on the surface of the lower mold to exchange heat with the lower mold, while the upper cooling structure is disposed on the surface of the upper mold to exchange heat with the upper mold.

[0008] Preferably, the distance between two adjacent sets of flow-blocking plates is consistent, and the flow-blocking plates are "S"-shaped structures made of metal, with a connecting port at the end of the flow-blocking plate.

[0009] Preferably, six sets of flow channels are evenly arranged inside the cooling channel, and adjacent sets of flow channels are connected by a connecting port. The inlet end of the cooling channel is provided with an inlet pipe, and the outlet end of the cooling channel is provided with an outlet pipe.

[0010] Preferably, the surface of the upper mold is covered with a sealing gasket, and a sealing cap is installed on the surface of the sealing gasket. The sealing cap covers the surface of the cooling channel and is fixed by screwing on multiple sets of fixing bolts.

[0011] Preferably, the surface of the upper mold is provided with a plurality of sets of screw holes, and the surface of the sealing gasket and the sealing cover is provided with a plurality of sets of through holes. At the same time, the fixing bolt passes through the through holes provided on the sealing cover and the sealing gasket and is screwed and fixed inside the screw holes provided on the surface of the upper mold.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This utility model achieves cooling of the product inside the upper mold by allowing liquid to circulate within multiple flow channels. Utilizing both upper and lower cooling structures, the upper and lower molds can be cooled and molded simultaneously. The synchronized liquid cooling structure ensures uniform temperature reduction in both molds, minimizing temperature differences between different parts of the mold. This allows all parts of the product to cool at a relatively consistent rate during molding, ensuring dimensional accuracy and quality stability, improving product consistency, and enhancing both product molding quality and mold molding efficiency.

[0014] 2. This utility model uses an "S"-shaped structure made of metal to create a flow-blocking plate. When the liquid flows inside the flow channel and impacts the surface of the flow-blocking plate, the flow velocity of the fluid inside the flow channel can be reduced, the residence time of the fluid inside the flow channel can be increased, and the cooling effect of the liquid on the upper mold can be improved.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This utility model provides an integrated molding mold for a passenger vehicle rear suspension lateral thrust rod support, including an upper mold 1, a lower mold 2 installed at the bottom of the upper mold 1, and a lower cooling structure 3 installed at the bottom of the lower mold 2. At the same time, an upper cooling structure 4 is installed on the surface of the upper mold 1. The upper cooling structure 4 includes a cooling channel 40 opened on the surface shell of the upper mold 1, and multiple sets of flow-blocking plates 44 are uniformly fixed inside the cooling channel 40. At the same time, a flow channel 46 is formed between the flow-blocking plates 44. A liquid inlet pipe 47 is fixedly installed on one side of the end of the upper mold 1, and a liquid outlet pipe 48 is installed on the upper side of the liquid inlet pipe 47.

[0022] Working Principle: Molten material enters the mold cavities inside the upper mold 1 and lower mold 2. After molding is completed inside the mold cavities, when demolding is required, the lower cooling structure 3, located on the surface of the lower mold 2, cools the lower mold 2; the upper cooling structure 4, located on the surface of the upper mold 1, cools the upper mold 1. Specifically, the lower cooling structure 3 and the upper cooling structure 4 operate in the same way. Here, only the operation of the upper cooling structure 4 is described: Coolant enters the cooling channel 40 through the inlet pipe 47. Multiple sets of flow-blocking plates 44 are evenly arranged inside the cooling channel 40, and six sets of flow channels 46 are evenly arranged inside the cooling channel 40. Adjacent sets of flow channels 46 are connected by a connecting port 45. When the liquid flows through the multiple sets of flow channels 46, it can cool the product inside the upper mold 1. By using the lower cooling structure 3 and the upper cooling structure 4, the upper mold 1 and the lower mold 2 can be cooled and molded simultaneously. The water-cooling structure with simultaneous liquid inlet cooling can ensure the cooling of the upper mold 1 and the lower mold 2. Uniform temperature drop minimizes temperature differences across different parts of the mold. This ensures that all parts of the product cool at a relatively consistent rate during molding, guaranteeing dimensional accuracy and quality stability, and improving product consistency. It also reduces mold thermal deformation. Uniform temperature distribution minimizes thermal deformation caused by uneven temperature distribution, which can affect molding accuracy and even damage the mold. Maintaining uniform mold temperature through a water-cooling structure extends mold life and reduces maintenance costs. The fixing bolt 43 passes through the through holes in the sealing cover 42 and sealing gasket 41 and is screwed into the screw hole on the surface of the upper mold 1. This allows the sealing cover 42 to cover the surface of the cooling channel 40 via the sealing gasket 41, preventing leakage. Simultaneously, the flow-blocking plate 44, made of metal in an "S" shape, reduces the flow velocity of liquid within the flow channel 46 as it flows and impacts the surface of the flow-blocking plate 44, improving the cooling effect on the upper mold 1.

[0023] The lower cooling structure 3 and the upper cooling structure 4 have the same composition. The lower cooling structure 3 is set on the surface of the lower mold 2 to exchange heat with the lower mold 2, while the upper cooling structure 4 is set on the surface of the upper mold 1 to exchange heat with the upper mold 1.

[0024] In a preferred embodiment, the distance between two adjacent sets of flow-blocking plates 44 is consistent, and the flow-blocking plate 44 is an "S"-shaped structure made of metal, and a connecting port 45 is provided at the end of the flow-blocking plate 44.

[0025] The cooling channel 40 is provided with six sets of flow channels 46 evenly arranged inside, and the two adjacent sets of flow channels 46 are connected by a connecting port 45. The inlet end of the cooling channel 40 is provided with an inlet pipe 47, and the outlet end of the cooling channel 40 is provided with an outlet pipe 48.

[0026] In a preferred embodiment, the surface of the upper mold 1 is covered with a sealing gasket 41, and a sealing cover 42 is installed on the surface of the sealing gasket 41. At the same time, the sealing cover 42 covers the surface of the cooling channel 40 and is fixed by screwing on multiple sets of fixing bolts 43.

[0027] Multiple sets of screw holes are evenly opened on the surface of the upper mold 1, and multiple sets of through holes are evenly opened on the surfaces of the sealing gasket 41 and the sealing cover 42. At the same time, the fixing bolt 43 passes through the through holes opened on the sealing cover 42 and the sealing gasket 41 and is screwed and fixed inside the screw holes opened on the surface of the upper mold 1.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
