Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, specifically to a die casting mold that facilitates material feeding. Background Technology

[0002] Die casting is a precision casting method that uses high pressure to inject molten metal into a mold cavity at high speed, and then rapidly solidifies it under pressure. It is widely used in the automotive, electronics, and aerospace industries. In modern times, the manufacturing industry's requirements for part precision and production efficiency have continuously increased, making die casting one of the mainstream forming technologies due to its high efficiency and precision. Especially in the electronics and automotive sectors, the widespread use of thin-walled and integrated parts has spurred the emergence of new technologies such as vacuum die casting and semi-solid die casting. At the same time, environmental protection concepts are driving the die casting process towards lower energy consumption and less pollution, and the introduction of digital monitoring systems has made process control more precise, forming a complete technical system from material research and development, equipment manufacturing to process optimization.

[0003] In existing technologies, mold opening methods are all based on traditional feeding positions. This method results in a large amount of cold material in the product, making molding difficult. It concentrates the cold material in the mold cavity on the other side of the product, causing the product to easily stick to the fixed mold during demolding, leading to mold ejection system failure. Moreover, due to the cold material issue, sand holes and casting defects may appear in the product wall in the cold material area. Subsequent powder coating processes on the product surface may cause bulging due to gas expansion caused by the sand holes, resulting in scrapped products and a high defect rate.

[0004] Therefore, we urgently need to provide a die-casting mold that facilitates material feeding. Utility Model Content

[0005] The purpose of this utility model is to provide a die-casting mold that facilitates material feeding, in order to solve the problems mentioned in the background art, where the cold material in the mold cavity is concentrated on the other side of the product, causing the product to easily stick to the fixed mold during demolding, resulting in the failure of the mold ejection system. Moreover, due to the cold material problem, sand holes and casting defects may appear in the product wall in the cold material area. In the subsequent powder coating process, the gas expansion caused by the sand holes will cause bulging on the product surface, resulting in scrapping of the molded product and a high defect rate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] The existing technology concentrates the cold material in the mold cavity on the other side of the product, causing the product to easily stick to the fixed mold during demolding, leading to mold ejection system failure. Furthermore, due to the cold material issue, the product wall in the cold material area may develop sand holes and incomplete casting. Subsequent powder coating processes may then cause bulging due to gas expansion from the sand holes, resulting in scrapped products and a high defect rate. Please refer to [reference needed]. Figures 1-4 The embodiment provides a die-casting mold that facilitates material feeding, which can effectively improve the yield rate of the product manufacturing process. The die-casting mold that facilitates material feeding includes a moving template 1, a demolding device installed on the top of the moving template 1, a fixed mold device installed on the top of the demolding device, and a forming device installed inside the fixed mold device.

[0021] The molding apparatus includes a flow-diverting structure and a molding structure, with the molding structure installed in the middle of the flow-diverting structure. The flow-diverting structure includes a flow-diverting cone 201, the top of which is mounted on an interlocking sleeve 202. A flow-diverting mold 203 is connected to the left side of the flow-diverting cone 201, and a moving mold core 205 is installed on the left side of the flow-diverting mold 203. A cold material collection bag 206 is installed in the middle of the top surface of the moving mold core 205. The molding structure includes a fixed mold core 204, with a molding mold 208 installed in the middle of the fixed mold core 204. A molded product 207 is disposed at the bottom of the molding mold 208.

[0022] The top surface of the flow divider 203 is provided with a flow divider groove. The interior of the flow divider groove on the top surface of the flow divider 203 is connected to the flow guide groove on the top surface of the flow divider cone 201 and the interior of the intersection sleeve 202. The fixed mold core 204 is installed on the top of the flow divider 203 and the moving mold core 205.

[0023] By setting up the molding device, the flow is guided by the flow divider cone 201, and the flow divider groove is opened on the top surface of the flow divider mold 203 and the fixed mold core 204 to divide the flow, realizing bidirectional feeding, reducing feeding time, and thus effectively improving the yield.

[0024] When the die-casting liquid is fed through the interlock sleeve 202, the liquid is guided by the flow divider cone 201 and the flow divider groove on the top of the flow divider mold 203, so that the liquid is fed and formed in two directions. This effectively reduces the time for the die-casting liquid to fill the forming cavity, prevents sand holes and casting leakage, and effectively improves the yield of the molded product 207. Example

[0025] Based on Implementation 1, the existing technology still has a problem where, during product demolding, the core clamping force can affect the ejection effect, thus impacting the product's demolding performance. Please refer to... Figures 1-4 This embodiment provides a die-casting mold that facilitates material feeding and effectively solves the problem of core clamping force. The die-casting mold includes a demolding device comprising an ejector back plate 101, an ejector panel 102 mounted on the top of the ejector back plate 101, ejector pins 103 installed inside the ejector back plate 101 and ejector panel 102, and reset rods 104 installed near the center of the left and right ends of the ejector back plate 101 and ejector panel 102. Support columns 105 are provided on the front and back sides of the ejector back plate 101 and ejector panel 102 near the left and right ends. The ejector back plate 101 and ejector panel 102 are installed between two moving mold plates 1, and the support columns 105 are installed inside the moving mold plates 1.

[0026] The fixed mold device includes a fixed mold plate 301, with a pin 302 installed in the middle of the top surface of the fixed mold plate 301, and a partition mold plate 303 connected to the bottom of the fixed mold plate 301. The bottom of the partition mold plate 303 is connected to the top of the moving mold plate 1, the middle of the top surface of the partition mold plate 303 is connected to the bottom of the fixed mold core 204 and the flow divider mold 203, the middle of the bottom surface of the fixed mold plate 301 is connected to the top of the fixed mold core 204, and the bottom end of the pin 302 is connected to the middle of the top surface of the fixed mold core 204.

[0027] By setting up the demolding device and the fixed mold device, and by using the two ends of the insert pin 302 to penetrate, the core clamping force of the fixed mold is reduced, so that the product remains in the direction of the moving mold when the mold is opened, ensuring that the ejection mechanism system will not fail.

[0028] After the product liquid is injected and die-cast into the molded part 207, when the ejector pin 103 is driven by the ejector pin back plate 101 and ejector pin panel 102 to eject and demold the product, the insert pin 302 pierces through the fixed mold plate 301, the moving mold core 205, the molding mold 208 and the two sections of the molded part 207, thereby effectively reducing the core clamping force during the demolding process, ensuring that the ejection mechanism will not fail, and completing the ejection and demolding work smoothly.
