[0002] Injection molding machines are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through an injection molding machine and a mold. Powder injection molding is a new type of near-net-shape forming technology in powder metallurgy that introduces modern plastic injection molding technology into the field of powder metallurgy. This technology uses a mold to uniformly mix metal powder with an organic binder, and then injects the mixture into the mold cavity at high temperature using an injection molding machine. After steps such as curing, debinding, and sintering, a structural part with high density, high precision, and complex three-dimensional shapes is finally obtained.

[0003] Existing injection molds have an injection tail at the injection end after the product is molded. After the product is unloaded, the injection tail needs to be removed manually. This process not only increases labor costs but also reduces production efficiency. Therefore, a porous venting powder injection mold is proposed to solve the problems mentioned above.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This embodiment of a porous venting powder injection mold includes a male mold 1 and a female mold 2. A mold 3 is fixedly installed on the right side of the male mold 1. A mold groove 4 is provided on the left side of the female mold 2. An injection port 5 extending to the mold groove 4 is opened on the left side of the female mold 2. A first movable groove 6 communicating with the injection port 5 is opened on the inner side of the female mold 2. A cutter 7 is slidably installed on the inner side of the first movable groove 6. A first electric telescopic rod 8 is fixedly installed on the top of the female mold 2. A first connecting rod 9 located in the first movable groove 6 is fixedly connected to the output end of the first electric telescopic rod 8. The top of the cutter 7 is fixedly connected to the bottom of the first connecting rod 9. An air pump 10 is fixedly installed on the top of the female mold 2. An air pipe 11 located at the right end of the injection port 5 and communicating with it is provided on the inner side of the female mold 2. The output end of the air pump 10 is connected to the air pipe 11. An injection head 12 is provided on the inner side of the right end. The air pipe 11 is located at one end of the injection port 5 and is inclined. When the air pump 10 sprays gas, the inclined air pipe 11 can better blow out the injection tail remaining in the injection port 5. When the product is being molded, the male mold 1 and the female mold 2 are closed. The injection head 12 is inserted into the injection port 5 and injects liquid material into the mold 3 and the mold groove 4. After the product is molded and cooled, the injection head 12 is withdrawn from the injection port 5. The first electric telescopic rod 8 is activated. The output end of the first electric telescopic rod 8 extends and pushes the cutter 7 downward to cut off the injection tail. After the male mold 1 and the female mold 2 are separated, the product is taken out. At the same time, the output end of the air pump 10 sprays air through the air pipe 11 to blow out the injection tail remaining in the injection port 5, realizing the automatic removal of the injection tail, reducing manual labor and improving production efficiency.

[0023] The bottom end of the cutter 7 is arc-shaped, and the size of the bottom end of the cutter 7 is adapted to the inner size of the injection port 5. By utilizing the shape of the bottom end of the cutter 7 adapted to the inner side of the injection port 5, the cutting of the injection tail end is clean, while reducing the space occupied by the first movable groove 6 inside the injection port 5, thus avoiding affecting the injection speed.

[0024] It should be noted that when the injection head 12 is inserted into the injection port 5, the left end of the injection head 12 should be positioned beyond the nozzle of the air tube 11 to prevent the injection material from entering the air tube 11.

[0025] In this embodiment, the cutter 7 has symmetrically arranged sealing mechanisms 13 on both the front and rear sides. The front sealing mechanism 13 includes a second movable groove 131 that communicates with the first movable groove 6. A sealing block 132 is slidably installed on the inner side of the second movable groove 131. A second connecting rod 133 is fixedly installed on the front side of the sealing block 132. A second electric telescopic rod 134 with its output end fixedly connected to the front end of the second connecting rod 133 is fixedly installed on the front side of the female mold 2. Before the injection molding operation, the cutter 7 retracts into the first movable groove 6, and the two second electric telescopic rods 134 are activated. The output ends of the second electric telescopic rods 134 extend out and push the sealing blocks 132 on both sides to close and seal the first movable groove 6, preventing liquid material from entering the first movable groove 6 during injection.

[0026] The bottom of the opposite end of the two sealing blocks 132 is arc-shaped, and the size and shape of the bottom of the opposite side of the two sealing blocks 132 are adapted to the inner size of the injection port 5. When the sealing blocks 132 on the front and rear sides are closed, the bottom of the sealing block 132 is similar in shape to the inner shape of the injection port 5, which can reduce the impact on the material injection speed during injection molding.

[0027] In this embodiment, cooling water inlets 14 are provided on both the front and rear sides of the male mold 1 and the female mold 2. Cooling water can be injected into the male mold 1 and the female mold 2 through the cooling water inlets 14 to quickly cool the product.

[0028] In this embodiment, a hanging ring 15 is fixedly installed on the top of the male mold 1 and the female mold 2. The hanging ring 15 is set to facilitate the lifting of the male mold 1 and the female mold 2 during installation.

[0029] In this embodiment, the mold 3 has multiple venting grooves 16 on its right side. The venting grooves 16 are located at the end of the material flow or at the thickest part of the workpiece, depending on the shape of the mold, to facilitate smoother venting.

[0030] The working principle of the above embodiments is as follows:

[0031] During product injection molding, the male mold 1 and female mold 2 are closed, and the injection head 12 is inserted into the injection port 5 to inject liquid material into the mold 3 and mold groove 4. After the product is formed and cooled, the injection head 12 is withdrawn from the injection port 5. First, the second electric telescopic rods 134 on both sides are activated. The output end of the second electric telescopic rod 134 retracts, causing the sealing blocks 132 on the front and rear sides to separate. At this time, the cutter 7 loses its limit and the first electric telescopic rod 8 is activated. The output end of the first electric telescopic rod 8 extends and pushes the cutter 7 downward to cut off the injection tail. After the male mold 1 and female mold 2 are separated, the product is taken out. At the same time, the output end of the air pump 10 sprays air through the air pipe 11 to blow out the injection tail remaining in the injection port 5, realizing automatic removal of the injection tail, reducing manual labor and improving production efficiency.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.

[0033] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
