[0002] An injection mold is a tool used to produce plastic products. It typically consists of two parts: a movable mold and a fixed mold. During the injection molding process, the plastic material is heated to a molten state, and then the molten plastic is injected into the mold cavity by the pressure of the injection molding machine. The shape and size of the cavity determine the shape and size of the final plastic product. Once the molten plastic fills the cavity, the mold is maintained at a certain temperature and pressure to ensure that the plastic is fully solidified and formed. Once the plastic product cools and solidifies, the mold is opened, the movable mold and the fixed mold are separated, and the plastic product is removed. Therefore, a special injection foam injection molding mold is particularly needed.

[0017] 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.

[0018] See also Figure 1-4 The utility model provides a technical solution: an injection foaming injection molding mold, comprising a support base 1, a lower mold 2 is mounted on the surface of the support base 1, a molding mechanism 3 is provided on one side of the surface of the support base 1, an injection tube 4 is sealedly connected to one side of the surface of the lower mold 2, and a temperature control mechanism 5 is provided inside the lower mold 2;

[0019] The temperature control mechanism 5 includes a controller 501, a battery box 502, a limit groove 503, a temperature sensor 504, a heat insulation layer 505 and a heating tube 506. The controller 501 is installed on the surface of the support seat 1, and the surface side of the controller 501 is connected to the battery box 502. The interior of the lower mold 2 is provided with a limit groove 503, and the surface side of the lower mold 2 is penetrated by a temperature sensor 504. The interior of the lower mold 2 is provided with a heat insulation layer 505, and the interior of the lower mold 2 is embedded with a heating tube 506. When controlling the temperature of the mold after injection molding, first set the controller 501 to a specific temperature according to the injection molding material, and then the battery box 502 is provided in the limit groove 503. The heating tube 506 in the inner part provides electricity to generate heat, while the heat insulation layer 505 blocks the heat, so that the heat is only transferred to the inner side of the lower mold 2. Then the temperature sensor 504 will monitor the temperature data inside the limit groove 503 in real time, and the obtained temperature data will be sent to the controller 501 in real time. When the temperature inside the limit groove 503 reaches a specific temperature, the controller 501 will control the battery box 502 to cut off the power. When the temperature inside the limit groove 503 drops, the controller 501 will control the battery box 502 to provide electricity to the heating tube 506, so that the temperature of the mold after injection molding is maintained within a certain temperature range, so as to improve the performance of the product during demolding.

[0020] Furthermore, the heating tube 506 is embedded in the interior of the lower mold 2, and the heating tube 506 fits against the inner wall of the lower mold 2. The thermal insulation layer 505 is made of glass fiber. Through the arrangement of the thermal insulation layer 505 and the heating tube 506, when in use, the thermal insulation layer 505 uses glass fiber for insulation, which can effectively prevent heat loss and transfer its heat only to the inner side of the lower mold 2. The heating tube 506 can provide heat for the lower mold 2, so that the injection mold is at a temperature suitable for demolding, which is convenient for subsequent demolding.

[0021] Furthermore, the temperature sensor 504 is electrically connected to the controller 501, and the heating tube 506 is electrically connected to the battery box 502. Through the setting of the temperature sensor 504, when in use, the temperature sensor 504 can monitor the temperature inside the limit groove 503 in real time, and then transmit the temperature data to the controller 501, which facilitates the subsequent controller 501 to control the opening and closing of the battery box 502 according to the temperature data.

[0022] Furthermore, the forming mechanism 3 includes an electric cylinder 301, a slot 302, a lubricating layer 303, an upper mold 304 and an exhaust pipe 305. The electric cylinder 301 is installed on one side of the surface of the support base 1, the slot 302 is opened on the surface of the lower mold 2, and the lubricating layer 303 is provided on the inner side of the lower mold 2. One end of the electric cylinder 301 is connected to the upper mold 304, and one side of the surface of the upper mold 304 is connected to the exhaust pipe 305. Through the arrangement of the electric cylinder 301, the slot 302, the lubricating layer 303, the upper mold 304 and the exhaust pipe 305, the upper mold 304 is provided with a lubricating layer 303. When in use, when injection molding a product, first start the electric cylinder 301, and then the electric cylinder 301 drives the upper mold 304 to engage the slot 302 on the surface of the lower mold 2, and then inject the foaming agent into the lower mold 2 through the injection tube 4. After the foaming agent is injected, a foaming reaction will be triggered to generate bubbles, which will be discharged through the exhaust pipe 305 to prevent the bubbles from being trapped in the mold and causing product defects or unevenness. After the product is molded, the lubricating layer 303 is coated on the inner side of the lower mold 2, so the product can be easily demoulded.

[0023] Furthermore, the slot 302 fits with one end of the upper mold 304, and the lubricating layer 303 is polytetrafluoroethylene. Through the setting of the lubricating layer 303, when in use, the lubricating layer 303 uses polytetrafluoroethylene to lubricate the inner side of the lower mold 2, thereby improving the demolding efficiency of the product after molding.

[0024] Working principle: First, when the product is injection molded, the electric cylinder 301 is started, and then the electric cylinder 301 drives the upper mold 304 to engage the slot 302 on the surface of the lower mold 2, and then the foaming agent is injected into the lower mold 2 through the injection tube 4. After the foaming agent is injected, a foaming reaction will be triggered to generate bubbles, which will be discharged through the exhaust pipe 305 to prevent the bubbles from being trapped in the mold, resulting in product defects or unevenness. After the product is formed, the lubricating layer 303 is coated on the inside of the lower mold 2, so the product can be easily demoulded. When controlling the temperature of the mold after injection molding, first set the controller 501 to a specific temperature according to the injection molding material, and then the battery box 502 is the limit The heating tube 506 inside the groove 503 provides electricity to generate heat, while the heat insulation layer 505 blocks the heat, allowing the heat to be transferred only to the inner side of the lower mold 2. Then the temperature sensor 504 will monitor the temperature data inside the limit groove 503 in real time, and the obtained temperature data will be sent to the controller 501 in real time. When the temperature inside the limit groove 503 reaches a specific temperature, the controller 501 will control the battery box 502 to cut off the power. When the temperature inside the limit groove 503 drops, the controller 501 will control the battery box 502 to provide electricity to the heating tube 506, so that the temperature of the mold after injection molding is maintained within a certain temperature range to improve the performance of the product during demolding.
