[0002] Plastic parts processing, also known as plastic molding processing, is a general term for various processes that transform synthetic resins or plastics into plastic products. It generally includes plastic formulation, molding, machining, joining, finishing and assembly, and the use of molds is involved in the plastic parts molding process.

[0003] For example, patent number CN221756607U discloses a plastic part processing mold, including a lower mold and an upper mold. The lower mold has a forming groove in the middle of its top end, and mounting grooves on both sides. T-shaped locking holes are formed on both sides of the bottom of the inner wall of the forming groove near the corresponding mounting groove. A fixing block is installed in the middle of one side of the inner wall of the mounting groove. A first electric hydraulic push rod is installed inside the fixing block. By rotating the support plate, the position of the upper mold can be adjusted. By using a second electric hydraulic push rod, the height of the upper mold can be adjusted, which facilitates the closing of the upper and lower molds. This reduces the difficulty of assembling and using the plastic part processing mold. The cooperation of the first electric hydraulic push rod and the push plate can lift the formed plastic part, reducing the difficulty of demolding and removing the formed plastic part, and making the plastic part processing mold easy to use.

[0004] However, the maintenance and replacement of the lower mold of existing plastic parts processing molds are relatively inconvenient, and the heat dissipation efficiency is low. At the same time, the lack of rapid cooling and efficient material ejection structure results in low material ejection efficiency for plastic parts. Utility Model Content

By setting an mounting base, the support plate can be easily limited, supported, and fixed, improving the assembly efficiency and stability of the support plate. By setting a movable plate, a transmission plate, and an ejector block, the molded plastic parts can be automatically ejected and unloaded, improving the unloading efficiency.

[0008] Preferably, the upper ends of the support frame and the base are fixedly connected, the lower end of the lower mold and the upper end of the support frame are engaged with each other, and the lower mold and the upper end of the support frame are detachably connected by bolts.

[0009] Preferably, the lower end of the lower mold has a through hole, the inner side of the through hole of the slide rod is slidably sleeved, the upper end of the slide rod extends to the inner side of the receiving groove through the through hole, the ejector block and the upper end of the slide rod are threadedly connected, and the ejector block and the inner side of the receiving groove and the through hole are mutually adapted.

[0014] The beneficial effects of this utility model are:

[0015] This easy-to-unload plastic part processing mold uses a hydraulic telescopic rod to drive the upper and lower molds to close. The transmission plate, under the pressure of the upper mold, drives the movable plate to descend, causing the slide rod to drive the ejector block into the receiving groove. At this time, the material is injected through the injection port of the upper mold, allowing it to cool and solidify between the upper and lower molds. The support frame improves heat dissipation efficiency. After molding, the hydraulic telescopic rod drives the upper mold to rise, and the movable plate, under the action of the spring, drives the ejector block to disengage from the receiving groove, ejecting the plastic part from the molding groove, achieving rapid demolding of the plastic part. Subsequently, by twisting the ejector block to disengage it from the upper end of the slide rod, and removing the bolts on the outside of the support frame, the lower mold can be removed from the support frame, facilitating maintenance or replacement of the lower mold.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a plastic part processing mold for easy material unloading, comprising a base 1, a support frame 2 at the upper end of the base 1, a lower mold 3 at the upper end of the support frame 2, a forming groove 4 at the upper end of the lower mold 3, a receiving groove 5 on the inner side of the forming groove 4, a movable plate 6 below the lower mold 3, a sliding rod 7 fixedly installed at the upper end of the movable plate 6, an ejector block 8 at the upper end of the sliding rod 7, a spring 9 at the lower end of the movable plate 6, transmission plates 10 on the left and right sides of the movable plate 6, sliding grooves 11 on the left and right sides of the upper end of the lower mold 3, an upper mold 12 above the lower mold 3, a column 13 fixedly installed at the rear side of the base 1, and a mounting base 14 fixedly installed at the upper end of the column 13. A support plate 15 is provided at the upper end of the mounting base 14, and a hydraulic telescopic rod 16 is provided at the front end of the support plate 15. The upper mold 12 and the lower mold 3 are closed, and the transmission plate 10 drives the ejector block 8 into the inner side of the receiving groove 5. At this time, the material is injected through the injection port of the upper mold 12, so that it cools and forms between the upper mold 12 and the lower mold 3. The heat dissipation efficiency is improved by the support of the support frame 2. After the forming is completed, the upper mold 12 rises, and the movable plate 6 drives the ejector block 8 to disengage from the receiving groove 5 under the action of the spring 9, and ejects the plastic part from the forming groove 4. Subsequently, by twisting the ejector block 8 to disengage it from the upper end of the slide rod 7, the bolt on the outside of the support frame 2 can be removed to remove the lower mold 3 from the support frame 2, which is convenient for maintenance or replacement of the lower mold 3.

[0024] Please see Figures 1-4In this embodiment, the upper ends of the support frame 2 and the base 1 are fixedly connected. The lower end of the lower mold 3 and the upper end of the support frame 2 are engaged with each other. The upper ends of the lower mold 3 and the support frame 2 are detachably connected by bolts. A through hole is provided at the lower end of the lower mold 3. The inner side of the through hole of the slide rod 7 is slidably sleeved. The upper end of the slide rod 7 extends to the inner side of the storage groove 5 through the through hole. The ejector block 8 is threadedly connected to the upper end of the slide rod 7. The ejector block 8, the storage groove 5, and the inner side of the through hole are mutually adapted. The lower end of the spring 9 is fixedly connected to the base 1. The upper end of plate 9 and the lower end of movable plate 6 are fixedly connected. The left and right ends of transmission plate 10 and movable plate 6 are fixedly connected. Slide 11 is arranged vertically through lower mold 3. The inner sides of transmission plate 10 and slide 11 are slidably connected. The upper mold 12 is driven to descend by hydraulic telescopic rod 16 to close with the lower mold 3. Transmission plate 10 slides along slide 11 under the pressure of upper mold 12, driving movable plate 6 to descend. Slide rod 7 drives ejector block 8 into the inner side of receiving groove 5. At this time, material is injected through injection port of upper mold 12. Cooling and molding occur between the upper mold 12 and the lower mold 3. The support frame 2 improves heat dissipation efficiency. After molding, the upper mold 12 rises via the hydraulic telescopic rod 16. The movable plate 6, under the action of the spring 9, causes the ejector block 8 to disengage from the receiving groove 5, ejecting the plastic part from the molding groove 4, thus achieving rapid demolding. For subsequent maintenance or replacement of the upper mold 12 and lower mold 3, the ejector block 8 is loosened to disengage from the upper end of the slide rod 7. At this point, removing the bolts on the outside of the support frame 2 allows the lower mold 3 to be removed from the support. Remove the upper mold 12 from the support frame 2 by removing the bolts at the lower end of the hydraulic telescopic rod 16. When reassembling, install the lower mold 3 on the upper end of the support frame 2, and then install the ejector block 8 on the upper end of the slide rod 7. At this time, place the upper mold 12 on the lower mold 3, and then fix the lower end of the hydraulic telescopic rod 16 to the upper mold 12 to achieve quick installation of the upper mold 12 and the lower mold 3. When disassembling and assembling the support plate 15, the support plate 15 is supported and limited by the mounting seat 14, which improves the stability of the support plate 15 installation.

[0025] Please see Figures 2-5 In this embodiment, a limiting groove 141 is provided at the upper end of the mounting base 14, and the inner sides of the support plate 15 and the limiting groove 141 are adapted to each other. A threaded post 142 is fixedly installed on the left side of the upper end of the mounting base 14. The rear end of the support plate 15 and the threaded post 142 are detachably connected by a nut. The hydraulic telescopic rod 16 is fixedly connected to the front end of the support plate 15. The lower end of the hydraulic telescopic rod 16 and the upper mold 12 are detachably connected by a connecting sleeve. A handle is fixedly installed at the upper end of the upper mold 12.

[0026] During operation, the hydraulic telescopic rod 16 lowers the upper mold 12 to close with the lower mold 3. The transmission plate 10, under pressure from the upper mold 12, slides along the slide groove 11, causing the movable plate 6 to descend. This allows the slide rod 7 to move the ejector block 8 into the receiving groove 5. At this time, material is injected through the injection port of the upper mold 12, allowing it to cool and solidify between the upper mold 12 and the lower mold 3. The support frame 2 improves heat dissipation efficiency. After molding, the hydraulic telescopic rod 16 raises the upper mold 12, and the movable plate 6, under the action of the spring 9, causes the ejector block 8 to disengage from the receiving groove 5, ejecting the plastic part from the molding groove 4, achieving rapid demolding of the plastic part. Subsequent maintenance or replacement is required. When installing the upper mold 12 and the lower mold 3, the ejector block 8 is turned to detach it from the upper end of the slide rod 7. At this time, the bolts on the outside of the support frame 2 can be removed to remove the lower mold 3 from the support frame 2. The upper mold 12 can be removed by removing the bolts at the lower end of the hydraulic telescopic rod 16. When reinstalling, the lower mold 3 is installed on the upper end of the support frame 2, and the ejector block 8 is installed on the upper end of the slide rod 7. The upper mold 12 is then placed on the lower mold 3, and the lower end of the hydraulic telescopic rod 16 is fixed to the upper mold 12, thus achieving quick installation of the upper mold 12 and the lower mold 3. When disassembling and assembling the support plate 15, the support plate 15 is supported and limited by the mounting base 14, which improves the stability of the support plate 15 installation.

[0027] Through the above steps, the upper mold 12 and the lower mold 3 are closed, and the transmission plate 10 drives the ejector block 8 into the inner side of the receiving groove 5. At this time, the material is injected through the injection port of the upper mold 12, which cools and forms between the upper mold 12 and the lower mold 3. The heat dissipation efficiency is improved by the support of the support frame 2. After the forming is completed, the upper mold 12 rises, and the movable plate 6 drives the ejector block 8 to disengage from the receiving groove 5 under the action of the spring 9, ejecting the plastic part from the forming groove 4. Subsequently, by twisting the ejector block 8 to disengage it from the upper end of the slide rod 7, the bolt on the outside of the support frame 2 can be removed to remove the lower mold 3 from the support frame 2. This solves the problems of inconvenient maintenance and replacement of the lower mold of the plastic part processing mold, low heat dissipation efficiency, lack of rapid cooling and efficient material pushing structure, resulting in low material feeding efficiency of plastic parts.
