Description

Technical Field

[0001] This utility model relates to a die-casting mold, and more particularly to a die-casting mold for the lower shell of an in-vehicle wireless charger. Background Technology

[0002] With the development of new energy vehicles, there are increasingly more styles of in-vehicle wireless chargers. However, the shell surface of a typical in-vehicle wireless charger is relatively large, requiring high processing precision. For the lower shell of an in-vehicle wireless charger, due to its large surface area, a large amount of air inside the mold cavity is difficult to completely expel during die casting, resulting in severe watermarks on the product surface and affecting product quality. Utility Model Content

[0003] The purpose of this utility model is to provide a die-casting mold for the lower shell of a vehicle-mounted wireless charger that can solve at least one of the above problems.

[0004] According to one aspect of this utility model, a die-casting mold for the lower shell of a vehicle-mounted wireless charger is provided, including an upper template, a lower template, an upper mold core, a lower mold core, a fixing plate, an ejector plate, and ejector pins. The upper template, lower template, and fixing plate are arranged sequentially from top to bottom. The upper mold core is fixed below the upper template, and the lower mold core is fixed above the lower template. The upper mold core and the lower mold core are arranged opposite to each other and form a cavity. The ejector plate is located inside the fixing plate. One end of the ejector pin is fixed to the ejector plate, and the other end can penetrate the lower template and the lower mold core and extend into the cavity. The lower mold core is provided with a slag-filled cavity, which is connected to the cavity. An exhaust channel is provided on the outer side of the slag-filled cavity, and the exhaust channel is located on the upper end face of the lower mold core.

[0005] The beneficial effects of this utility model are: by providing a slag cavity, excess material can be easily pressed into the slag cavity when the product is die-cast in the mold cavity; by providing an exhaust channel, the gas in the mold cavity can be discharged through the exhaust channel when the product is die-cast in the mold cavity, thereby preventing the generation of watermarks on the product surface and ensuring product quality.

[0006] In some embodiments, the venting channel includes a first channel and a second channel. There are two first channels, both of which are connected to the slag cavity, and the second channel is located between the two first channels. Thus, by providing multiple venting channels, the venting area can be increased, which is beneficial for the discharge of gas from the mold cavity.

[0007] In some embodiments, the first channel includes a first inclined channel, a second inclined channel, and a horizontal channel connected in sequence, with the first inclined channel communicating with the slag cavity. Thus, by passing through the various parts of the first channel, the length of the exhaust channel can be increased, facilitating the discharge of gas from the mold cavity.

[0008] In some embodiments, the die-casting mold for the lower shell of the vehicle-mounted wireless charger further includes an upper venting block and a lower venting block. The upper venting block is fixed on the upper template and located outside the upper mold core, while the lower venting block is fixed on the lower template and located outside the lower mold core. The upper and lower venting blocks are correspondingly arranged, forming a venting cavity between them, and the venting channel communicates with the venting cavity. Therefore, by providing a venting cavity, the venting area can be further increased based on the venting channel, allowing air to be discharged over a large area. This facilitates the full discharge of air from the mold cavity during die casting, thereby effectively controlling the formation of watermarks on the product surface.

[0009] In some embodiments, the lower exhaust block has multiple exhaust slots. Therefore, by providing multiple exhaust slots, the airflow channels within the exhaust chamber can be increased.

[0010] In some embodiments, the die-casting mold for the lower shell of the vehicle-mounted wireless charger also includes a feeding pipe, and a flow channel is provided on the lower mold core, which communicates with the cavity. The feeding pipe passes through the upper mold plate and then connects downwards with the flow channel. This facilitates the flow of die-casting material into the cavity.

[0011] In some embodiments, the die-casting mold for the lower shell of the vehicle-mounted wireless charger also includes guide pillars, which are sleeved on the ejector plate. Thus, the guide pillars guide the movement of the ejector plate. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings.

[0016] Reference Figures 1-3The die-casting mold for the lower shell of the vehicle wireless charger includes an upper mold plate 1, a lower mold plate 2, an upper mold core 3, a lower mold core 4, a fixing plate 5, an ejector plate 6, and an ejector pin 7. The upper mold plate 1, the lower mold plate 2, and the fixing plate 5 are arranged sequentially from top to bottom. The upper mold core 3 is fixed below the upper mold plate 1, and the lower mold core 4 is fixed above the lower mold plate 2. The upper mold core 3 and the lower mold core 4 are arranged opposite to each other and form a cavity. The ejector plate 6 is located inside the fixing plate 5. One end of the ejector pin 7 is fixed on the ejector plate 6, and the other end can penetrate the lower mold plate 2 and the lower mold core 4 and extend into the cavity. The lower mold core 4 is provided with a slag-filled cavity 41, which is connected to the cavity. An exhaust channel 8 is provided on the outer side of the slag-filled cavity 41, and the exhaust channel 8 is located on the upper end face of the lower mold core 4.

[0017] In use, the die-casting mold for the lower shell of this vehicle-mounted wireless charger allows for pouring of material into the cavity after the upper mold core 3 and lower mold core 4 mate. The mold then performs die casting on the fluid within the cavity, resulting in the lower shell of the vehicle-mounted wireless charger. During die casting, excess material is forced into the slag pocket cavity 41, forming a slag pocket. After the product is die-cast and demolded, the slag pocket is removed, preventing excess material from remaining in the cavity. When the product is being die-cast in the cavity, air within the cavity can be expelled along the exhaust channel 8, preventing air from remaining in the cavity. This effectively controls watermarks on the surface of the die-cast product, improving product quality.

[0018] The exhaust channel 8 includes a first channel 81 and a second channel 82. There are two first channels 81, both of which are connected to the slag cavity 41. The second channel 82 is located between the two first channels 81. Thus, through multiple channels, air in the cavity can be easily discharged from multiple locations, which is conducive to the rapid discharge of air.

[0019] The first channel 81 includes a first inclined channel 811, a second inclined channel 812, and a horizontal channel 813 connected in sequence. The first inclined channel 811 is connected to the slag cavity 41. The arrangement of the various parts of the first channel 81 greatly increases the length of the first channel 81, which is conducive to the discharge of air from the cavity.

[0020] The die-casting mold for the lower shell of the vehicle-mounted wireless charger of this utility model also includes an upper venting block 9 and a lower venting block 10. The upper venting block 9 is fixed on the upper template 1 and located on the outside of the upper mold core 3. The lower venting block 10 is fixed on the lower template 2 and located on the outside of the lower mold core 4. The upper venting block 9 and the lower venting block 10 are correspondingly arranged, and an venting cavity is formed between the two lower venting blocks 10. The venting channel 8 communicates with the venting cavity. Among them, the lower venting block 10 has multiple venting grooves 101.

[0021] Therefore, when the product in the mold cavity is being die-cast, the air in the mold cavity is discharged through the exhaust channel 8 and enters the exhaust groove 101. By providing an exhaust cavity and multiple exhaust grooves 101, the exhaust cavity forms a sheet-like exhaust surface, increasing the exhaust area. This allows the air discharged from the exhaust channel 8 to enter the exhaust cavity, facilitating the full discharge of air from the mold cavity, effectively preventing the formation of watermarks on the product surface, and ensuring product quality.

[0022] The die-casting mold for the lower shell of the vehicle-mounted wireless charger also includes a feeding pipe 20. The lower mold core 4 is provided with a flow channel 42, which is connected to the cavity. The feeding pipe 20 passes through the upper mold plate 1 and connects downward to the flow channel 42. The feeding pipe 20 facilitates connection with an external material conveying structure and conveys die-casting material into the flow channel 42, which then flows into the cavity.

[0023] The die-casting mold for the lower shell of the vehicle wireless charger also includes guide pillars 30, which are sleeved on the ejector plate 6. By providing guide pillars 30, the lifting and lowering of the ejector plate 6 can be guided, thereby facilitating the smooth lifting and lowering of the ejector plate 6.

[0024] The specific working process of the die-casting mold for the lower shell of the vehicle-mounted wireless charger of this utility model is as follows:

[0025] When the product needs to be die-cast, the upper mold plate 1 moves the upper mold core 3 to the lower mold plate 2 until the upper mold core 3 and the lower mold core 4 are engaged. Once the upper mold core 3 and the lower mold core 4 are in place, the mold is closed. Then, material is fed into the flow channel 42 through the feeding pipe 20, filling the cavity and completing the die-casting process within the cavity. During die-casting, the gas inside the cavity is discharged through the venting channel 8 and enters the venting chamber, ensuring the quality of the die-cast product.

[0026] After the product is die-cast, the mold is opened. The upper mold plate 1 drives the upper mold core 3 to move upward and away from the lower mold plate 2, so that the upper mold core 3 is separated from the product die-cast in the cavity. When the upper mold plate 1 moves into place, the ejector plate 6 moves upward and the ejector pin 7 moves upward with the ejector plate 6, so that the ejector pin 7 pushes the product out of the cavity, realizing the demolding of the product.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
