[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the left view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 An injection molding equipment with cooling water filtration function includes a fixed mold device 1 and a moving mold device 2;

[0031] The fixed mold device 1 includes a fixed mold body 11 for fixing and cooperating with the moving mold device 2 to form an injection cavity, and a follow-up demolding component 12 for moving and demolding synchronously with the moving mold device 2. The follow-up demolding component 12 is installed on the fixed mold body 11, and the fixed mold body 11 is connected to the moving mold device 2.

[0032] When the injection molding equipment with cooling water filtration function is in normal use, the moving mold device 2 moves toward the fixed mold body 11, and a cavity is formed between the moving mold device 2 and the fixed mold body 11 for injection molding. After injection molding, the moving mold device 2 moves away from the fixed mold body 11, and at the same time drives the follow-up demolding component 12 to move so that the product leaves the cavity and completes automatic unloading. By setting the follow-up demolding component 12 to follow the moving mold device 2 to move automatically, the product is automatically unloaded when demolded after molding, as the moving mold device 2 moves away. No additional drive is required for unloading, saving energy, with high synchronization and low cost.

[0033] The fixed mold body 11 includes a fixed mold 111, a fixed plate 112, and a filter 113. The fixed mold 111 is fixedly installed on the front end of the fixed plate 112.

[0036] The moving mold body 21 includes a moving mold 211, a connecting plate 212, an injection tube 213, and two material feeding auxiliary rods 215. The moving mold 211 is fixedly installed at the rear end of the connecting plate 212. The rear end of the moving mold 211 has a groove that cooperates with the fixed mold 111 to form a cavity. The injection tube 213 is located inside the moving mold 211. One end of the injection tube 213 is connected to the groove of the moving mold 211, and the other end of the injection tube 213 is connected to the feeding device. The two material feeding auxiliary rods 215 are symmetrically arranged and fixedly installed at the rear end of the moving mold 211. The material feeding auxiliary rods 215 are in close contact with the fixed mold 111 and are slidably connected. The rear end of the material feeding auxiliary rods 215 is gradually inclined inward from back to front to correspond to the rear end of the locking block 124.

[0037] The feeding auxiliary rod 215 is composed of a rear section and a front section. The rear section and the front section of the feeding auxiliary rod 215 are fixedly connected by bolts. Multiple adjustment holes are provided on the rear section and the front section of the feeding auxiliary rod 215 to adapt to different feeding strokes and change the bolt position.

[0038] The fixed mold 111 is provided with multiple positioning holes 115 at its front end, and the moving mold 211 is fixedly installed with multiple positioning rods 214 at its rear end, with the positioning holes 115 and the positioning rods 214 being set in correspondence.

[0039] The release agent spraying assembly 22 includes a release agent mounting component and an automatic pressing component. The release agent mounting component is installed on the outside of the material feeding auxiliary rod 215, and the automatic pressing component is installed at the front end of the release agent mounting component.

[0040] The mold release agent installation component includes an installation frame 221, a clamping block 222, a threaded rod 223, and a nut 224. The installation frame 221 is fixedly installed on the outside of the material feeding auxiliary rod 215. One end of the threaded rod 223 passes through the installation frame 221 and is fixedly connected to the clamping block 222. A limit rod is fixedly installed on the outside of the clamping block 222, passing through the installation frame 221 to limit the movement of the clamping block 222. The outside of the threaded rod 223 is threadedly connected to the nut 224. The nut 224 is rotatably connected to the installation frame 221. The front end of the installation frame 221 is connected to the automatic pressing component.

[0041] The automatic pressing component includes a cylinder 225 and a lower pressure plate 226. The cylinder 225 is fixedly installed on one side of the mounting frame 221. The output end of the cylinder 225 is fixedly connected to the lower pressure plate 226. The lower end of the lower pressure plate 226 is provided with a protrusion facing the mounting frame 221 for pressing. The output direction of the cylinder 225 is set up and down. A press-type canned release agent is placed inside the mounting frame 221.

[0042] During normal use, the injection molding equipment with cooling water filtration function moves the moving mold 211 toward the fixed mold 111 until they are in contact. Injection is then performed from the injection pipe 213 between the moving mold 211 and the fixed mold 111. Cooling water, after cooling the product through the cooling water channel 114, enters the filter 113 from the outlet for filtration. After the product is formed, the moving mold 211 is moved away from the fixed mold 111. The moving mold 211 moves the unloading auxiliary rod 215. After the unloading auxiliary rod 215 contacts the clamping block 124, it sequentially moves the clamping block 124, the push plate 122, and the push rod 121. The push plate 122 compresses the spring 123, and the push rod 121 pushes the product inside the fixed mold 111 for unloading. At this time, the mounting bracket 221 is located outside the fixed mold 111. The cylinder 225 is activated, causing the lower pressure plate 226 to move downwards and activating the press-type canned release agent. The press-type canned release agent sprays the release agent... The release agent is sprayed into the groove of the fixed mold 111. The above steps are repeated to complete the automated injection molding. The length of the discharge auxiliary rod 215 is adjusted according to the discharge stroke of different injection molded products. When the release agent of the press-type can is used up, the nut 224 is turned. The nut 224 drives the threaded rod 223 to move. The threaded rod 223 drives the clamping block 222 to disengage from the press-type can release agent. After changing and adjusting the angle of the press-type can release agent, the nut 224 is turned to clamp and fix it. The segmented adjustment setting of the discharge auxiliary rod 215 can be adapted to the discharge stroke of different products, and has a wide range of applications. The cylinder 225 and the lower pressure plate 226 can automatically spray the release agent into the inner side of the fixed mold 111. At the same time, the clamping setting of the nut 224 and the threaded rod 223 to clamp the press-type can release agent is easy to replace and use.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
