Description

Technical Field

[0001] This utility model relates to the field of injection molds, and more specifically, it relates to an injection mold with a rapid cooling channel. Background Technology

[0002] Injection molds are tools used for molding plastic products. They mainly consist of an upper mold, a lower mold, and a cavity. Their working principle involves injecting molten plastic into the mold cavity through an injection molding machine. After cooling and solidification, the desired plastic product is formed. The shape of the mold cavity determines the product's shape and structure.

[0003] Currently, in order to improve the molding speed of injection molds, rapid cooling channels are generally set inside them to quickly cool and shape the plastic in the injection mold. However, most of the rapid cooling channels are now fixed inside the injection mold during the manufacturing process and are difficult to disassemble. Once blockage, leakage or damage occurs, repair and cleaning are very difficult, often requiring the entire mold to be disassembled and reprocessed, resulting in production stagnation and increased costs.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an injection mold with a rapid cooling channel. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an injection mold with a rapid cooling channel.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an injection mold with a rapid cooling channel, comprising a mold body and a mold bottom, which are detachably connected. The top of the mold bottom is equipped with a rapid cooling channel made of a rigid material, and the bottom of the mold body is provided with a frame-shaped groove for the rapid cooling channel to be inserted near its cavity.

[0007] Preferably, the rapid cooling channel is made of aluminum tube with a square cross-section. Aluminum tube conducts heat quickly, which can make the temperature distribution inside the mold more uniform.

[0008] Preferably, the rapid cooling channel is provided with an inlet pipe at one end and an outlet pipe at the other end. The part of the rapid cooling channel near the outlet pipe is embedded and fixed in the bottom of the mold, and the outlet pipe extends out from the side end of the bottom of the mold. The top of the mold body is provided with a through hole A for the inlet pipe to pass through.

[0009] Preferably, the mold body and the mold bottom are detachably connected by a quick-release assembly.

[0010] Preferably, the quick-release assembly includes a lower opening slot seat fixed on the front and rear sides of the mold body, and a connecting plate fixed on the front and rear sides of the bottom of the mold. The top of each lower opening slot seat is provided with a through hole B. The top of the connecting plate is fixedly connected with a protrusion that matches the lower opening slot seat, and the top of the protrusion is fixedly connected with a screw that can pass through the through hole B.

[0011] Preferably, thermally conductive silicone is adhered to the outer wall of the rapid cooling channel to improve heat conduction efficiency.

[0012] Preferably, the two sides of the rapid cooling channel are connected to the bottom of the mold by reinforcing plates, making the shape of the rapid cooling channel more stable.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Since the mold body and the bottom of the mold are detachably connected, the rapid cooling channel can be pulled out from the mold body simply by separating the two. Therefore, if there is a problem with the rapid cooling channel, it is not necessary to disassemble the entire injection mold and reprocess it.

[0015] 2. When the mold body and the mold bottom are assembled together, the water inlet pipe passes through the through hole A at the top of the mold body, while the water outlet pipe extends from the side end of the mold bottom, making it easy for both to be connected to the pipes on the cooling device.

[0016] 3. Thermally conductive silicone is bonded to the outer wall of the rapid cooling channel of this utility model. Thermally conductive silicone is a common elastic thermally conductive material. When the cooling channel is inserted into the mold body, it will be squeezed, thus making close contact with the inner surface of the injection mold. This design can fill the tiny gap between the rapid cooling channel and the mold and improve the heat conduction efficiency.

[0017] 4. The two sides of the rapid cooling channel of this utility model are connected to the bottom of the mold by reinforcing plates, which makes the shape of the rapid cooling channel more stable. Attached Figure Description

[0024] like Figure 1-4 As shown, this utility model provides an injection mold with a rapid cooling channel, including a mold body 1 and a mold bottom 2, which are detachably connected. The top of the mold bottom 2 is equipped with a rapid cooling channel 3 made of a rigid material, and a frame-shaped groove 4 for the rapid cooling channel 3 to be inserted is provided at the bottom of the mold body 1 near its cavity.

[0025] In use, the mold body 1 and the mold bottom 2 are assembled. After assembly, the rapid cooling channel 3 on the mold bottom 2 is inserted into the frame groove 4 of the mold body 1. When coolant is introduced into the rapid cooling channel 3, the heat inside the injection mold can be quickly carried out by the rapid cooling channel 3, thereby cooling the plastic inside the mold. Since the mold body 1 and the mold bottom 2 are detachably connected, the rapid cooling channel 3 can be pulled out from the mold body 1 simply by separating the two. Therefore, if there is a problem with the rapid cooling channel 3, it is not necessary to disassemble the entire injection mold and reprocess it.

[0026] The rapid cooling channel 3 of this invention is made of aluminum tubing. Aluminum tubing conducts heat quickly, enabling a more uniform temperature distribution within the mold. In injection molding, temperature uniformity is crucial to product quality. Its square transverse shape facilitates its fit against the inner surface of the mold body 1. Furthermore, thermally conductive silicone, a common elastic thermally conductive material, is adhered to the outer wall of the rapid cooling channel 3. When the cooling channel is inserted into the mold body 1, it is compressed, resulting in close contact with the inner surface of the injection mold. This design fills the tiny gaps between the rapid cooling channel 3 and the mold, improving heat transfer efficiency. Moreover, the two sides of the rapid cooling channel 3 are connected to the bottom 2 of the mold via reinforcing plates 9, further stabilizing the shape of the rapid cooling channel 3.

[0027] A water inlet pipe 5 is provided at one end of the rapid cooling channel 3, and a water outlet pipe 6 is provided at the other end. The part of the rapid cooling channel 3 near the water outlet pipe 6 is embedded and fixed in the bottom of the mold 2, and the water outlet pipe 6 extends out from the side end of the bottom of the mold 2. A through hole A7 is provided at the top of the mold body 1 for the water inlet pipe 5 to pass through. The water inlet pipe 5 and the water outlet pipe 6 are respectively connected to the cooling device, so that coolant circulates in the rapid cooling channel 3. When the mold body 1 and the mold bottom 2 are assembled together, the water inlet pipe 5 passes out from the through hole A7 at the top of the mold body 1, while the water outlet pipe 6 itself extends out from the side end of the bottom of the mold 2, so that the two can be connected to the pipes on the cooling device.

[0028] Furthermore, the mold body 1 and the mold bottom 2 are detachably connected via a quick-release assembly 8. The quick-release assembly 8 includes lower opening slot seats 801 fixed to the front and rear sides of the mold body 1, and connecting plates 803 fixed to the front and rear sides of the mold bottom 2. Each lower opening slot seat 801 has a through hole B802 at its top. A protrusion 804 adapted to the lower opening slot seat 801 is fixedly connected to the top of the connecting plate 803, and a screw 805 capable of passing through the through hole B802 is fixedly connected to the top of the protrusion 804. When the protrusion 804 on the mold bottom 2 is inserted into the lower opening slot seat 801 of the mold body 1 for positioning, the rapid cooling channel 3 of the mold bottom 2 also... Insert the protrusion 804 into the frame groove 4 on the mold body 1. At this time, the screw 805 on the protrusion 804 also passes through the through hole B802 on the lower opening slot seat 801. Then, rotate the nut clockwise to install the nut on the screw 805. The nut moves downward along the screw 805 and slowly abuts against the top of the lower opening slot seat 801, thus fixing the protrusion 804 in the lower opening slot seat 801. This completes the assembly between the mold body 1 and the mold bottom 2. This method of limiting and then fixing can ensure the accuracy of the assembly position. Conversely, remove the nut and pull the protrusion 804 out of the lower opening slot seat 801 to complete the disassembly between the mold body 1 and the mold bottom 2.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
