Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and particularly relates to an injection mold for automobile parts. Background Art

[0002] Automobiles are the most common means of transportation at present. As the basis of the automobile industry, automobile parts are necessary factors to support the sustainable and healthy development of the automobile industry. Most automobile parts are made of plastic. When processing and producing automobile parts, injection molds are usually used for injection molding production.

[0003] At present, when using injection molds, there is a lack of an auxiliary unloading and guiding mechanism. Usually, after the injection molding of automobile parts is completed, the ejection action of the injection molded parts is completed by the moving die displacement ejector pin. The automobile parts fall freely under the action of their own weight. Due to the large falling distance, the surface of the injection molded parts is easily damaged, which not only affects the injection molding effect, but also causes the production quality of automobile parts to decline. Therefore, an injection mold for automobile parts is proposed to facilitate the addition of an auxiliary unloading and guiding mechanism. After the injection molding of automobile parts is completed, the freely falling injection molded parts are subjected to auxiliary buffering and guiding treatment to improve the stability of falling and recycling, and it is more difficult to appear surface damage, thereby improving the use effect.

[0029] The material guide assembly 3 includes a fixed seat 301, and the bottom of the movable mold 2 is connected to the fixed seat 301 by bolts, a material guide plate 302 is rotatably connected between the fixed seats 301, both ends of the material guide plate 302 are connected to the rotating shaft 303 by bolts, and the material guide plate 302 is rotatably connected to the fixed seat 301 through the rotating shaft 303, and the surface of the material guide plate 302 is connected to a sponge pad 304 by gluing.

[0030] When in use, an auxiliary unloading and guiding mechanism can be added through the fixed seat 301, the guide plate 302, the rotating shaft 303 and the sponge pad 304. The material receiving and buffering method is used to improve the stability of injection molded parts unloading, making it more flexible and reliable to use, and avoiding damage caused by the falling of injection molded parts.

[0031] In order to improve the stability of the mold, for example, Figure 1 , Figure 3 As shown, the utility model also includes that the auxiliary component 4 includes a U-shaped frame 401, and the fixed mold 1 is connected to the U-shaped frame 401 by bolts, the U-shaped frame 401 is rotatably connected to the rotating frame 402 through a rotating shaft, one side of the rotating frame 402 is connected to the flow equalizing plate 403 by bolts, and the other side of the rotating frame 402 is connected to the fan 404 by bolts, and the air outlet end of the fan 404 is connected to the flow equalizing plate 403 through a hose, the top of the U-shaped frame 401 is connected to the servo motor 405 by bolts, and the servo motor 405 is connected to the rotating frame 402 through a driving shaft.

[0032] When in use, an auxiliary heat dissipation mechanism can be added through the U-shaped frame 401, the rotating frame 402, the flow equalizing plate 403 and the fan 404, and the mold can be cooled by blowing air, which slows down the deformation speed of the mold, improves the stability of the mold, and also assists in cleaning waste chips.

[0033] For example, Figure 2 As shown, the utility model also includes that a coil spring 305 is sleeved on the outer periphery of the rotating shaft 303 , one end of the coil spring 305 is connected to the rotating shaft 303 by welding, and the other end of the coil spring 305 is connected to the fixing seat 301 by a slot.

[0035] For example, Figure 4 As shown, the utility model further includes that an injection cavity 101 is opened in the fixed mold 1 , and an injection port 102 is opened on a surface of the fixed mold 1 away from the movable mold 2 , and the injection port 102 is connected to the injection cavity 101 .

[0036] During use, it is convenient to connect an injection molding machine for injection molding through the injection cavity 101 and the injection port 102.

[0037] Exemplarily, such as Figure 4 As shown, the present utility model further includes that the push plate 5 includes a connecting rod 501, and both ends of the connecting rod 501 are fixedly connected to the push plate 5 and the moving mold 2 by bolts.

[0040] During use, through the sliding frame 601, the thimble 602, the spring 603 and the push rod 604, an auxiliary demolding mechanism can be added to push down the injection molded part for unloading.

[0041] When the present utility model is in use, first, the operator fixedly installs and connects the fixed mold 1 and the moving mold 2 of the injection mold by bolts. At the same time, the operator manually turns on the injection molding machine, and performs injection molding through the injection port 102 and the injection cavity 101.

When the injection molded part falls, it first comes into buffered contact with the sponge pad 304 of the guide plate 302, and then slides down from the guide plate 302, playing an auxiliary buffering and guiding effect, which can avoid damage caused by falling, thereby improving the quality of injection molding;

[0042] At the same time, during the unloading operation, the operator can also manually turn on the servo motor 405 to drive the rotating frame 402 to rotate, so that the flow equalizing plate 403 is located between the fixed mold 1 and the moving mold 2. Then, the operator manually turns on the fan 404, and the flow equalizing plate 403 is used to perform auxiliary heat dissipation treatment on the inside of the moving mold 2. At the same time, it can also play an auxiliary cleaning effect, avoiding deformation of the mold caused by high temperature, improving the actual use effect, and being beneficial to extending the service life.
