Technical Field

[0001] The utility model relates to the technical field of plastic product forming molds, in particular to a forming mold based on plastic product processing. Background Art

[0002] Plastic products are a general term for household and industrial products made primarily from plastic. This encompasses products made using all processes, including injection molding and vacuum forming. Plastic is a type of synthetic molecular material with plasticity. Along with synthetic rubber and synthetic fibers, it forms one of the three most essential synthetic materials in daily life. Specifically, plastic is primarily composed of natural or synthetic resins, with various additives added. It can be molded into a specific shape under certain conditions of temperature and pressure, and retains its shape at room temperature.

[0003] Existing plastic molding molds need to be lubricated to improve demolding efficiency. However, each injection molding process requires workers to apply a layer of lubricant. The lubricant application method is relatively complicated, which will significantly increase the production cycle time, thereby affecting the overall production efficiency. Therefore, it is necessary to provide a molding mold that can quickly lubricate the upper mold to improve demolding efficiency. Utility Model Content

[0004] The purpose of the present utility model is to provide a molding die based on plastic product processing to solve the problem raised in the above background technology that the existing plastic molding die needs to be coated with lubricating oil to improve the efficiency of demolding, but each injection molding requires the staff to apply a layer of lubricating oil. The method of applying lubricating oil is relatively complicated, which will significantly increase the production cycle time, thereby affecting the overall production efficiency.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a forming mold based on plastic product processing, comprising:

[0007] A forming assembly, comprising an operating table and a support plate, wherein the support plate is fixed to the rear side of the upper surface of the operating table and is L-shaped;

[0008] A lubrication assembly includes a slide, a slide rod, a spring, a connecting frame and a hair roller. The slide is opened in the middle of the front side of the outer surface of the support plate, the slide rod is slidably installed inside the slide, four springs are equidistantly fixed on the upper surface of the slide rod, the connecting frame is fixedly connected to the upper end of the spring, and the hair roller is rotatably installed inside the connecting frame.

[0009] Furthermore, the forming assembly also includes a base frame, a hydraulic rod, an upper module and a lower module. The base frame is fixed on both sides of the lower surface of the operating table, the hydraulic rod is fixed on the upper surface of the support plate, the upper module is fixedly connected to the lower surface of the support plate, and the lower module is fixed on the upper surface of the operating table.

[0010] Furthermore, the lubrication assembly also includes a support frame and a limit plate. The support frame is fixed on both sides of the center of the upper surface of the operating table and is located on both sides of the lower module. The limit plate is fixed in the middle of the two support frames, and a square groove is opened in the center of the limit plate.

[0011] Furthermore, a handle is fixedly connected to the front side wall of the sliding rod, and the handle is slidably installed in the square groove in the middle of the limiting plate.

[0012] Furthermore, it also includes a cutting assembly, which includes a mounting groove, a circular hole, a cutting knife and an electric push rod. The mounting groove is opened on the lower surface of the upper module, and the circular hole is opened on the upper surface of the upper module. The cutting knife is slidably installed inside the mounting groove, and the electric push rod is fixedly connected to the upper surface of the cutting knife.

[0013] Furthermore, the output end of the electric push rod passes through the circular hole, and the cutting knife moves vertically up and down in the installation groove.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The utility model has a molding component and a lubrication component. Before injection molding, the staff only needs to inject lubricating oil into the connecting frame, then hold the handle and drive the handle to move in the square groove of the limit plate. At this time, the handle will drive the slide rod to move in the slide groove, and synchronously drive the spring to move. When the hair roller contacts the upper module, the spring will be compressed downward, and under the elastic force of the spring, the hair roller is always in contact with the upper module, and lubricating oil is applied to the surface of the upper module. The operation is simple. The operator only needs to inject lubricating oil into the connecting frame, and then move the handle to drive the slide rod and hair roller to complete the lubrication. The whole process is simple and clear. Through the simplified lubrication steps, the preparation time before each production can be significantly reduced, thereby improving the overall production efficiency.

[0016] 2. Based on the first beneficial effect, through the setting of the cutting assembly, when the upper module is pressed inside the lower module, after the product is formed, there will be burrs around the product, which needs to be cut flat again. At this time, the staff only needs to use the external controller to control the extension and retraction of the electric push rod. The output end of the electric push rod extends downward, and at the same time drives the cutting knife to move downward and move out of the installation slot. The hydraulic rod is pressed downward again to make the upper module fit the lower module. At this time, the cutting knife can cut off the excess burrs cleanly, and the burr removal work can be completed quickly, which greatly shortens the total cycle from product molding to finished product.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] See also Figure 1-Figure 4 As shown, this embodiment is a molding die based on plastic product processing, comprising:

[0031] The forming assembly includes an operating table 11 and a support plate 13. The support plate 13 is fixed to the rear side of the upper surface of the operating table 11 and is L-shaped. The forming assembly also includes a base frame 12, a hydraulic rod 14, an upper module 15 and a lower module 16. The base frame 12 is fixed to both sides of the lower surface of the operating table 11, the hydraulic rod 14 is fixed to the upper surface of the support plate 13, the upper module 15 is fixedly connected to the lower surface of the support plate 13, and the lower module 16 is fixed to the upper surface of the operating table 11;

[0032] The operating table 11 serves as the basic platform of the entire lubrication system. The operating table 11 provides stable support and installation position for other components. The upper module 15 is a key component of the lubrication system and is directly involved in the lubrication process of the mold.

[0033] The lubrication assembly includes a chute 21, a slide rod 23, a spring 24, a connecting frame 25, and a hair roller 26. The chute 21 is opened in the middle of the front side of the outer surface of the support plate 13. The slide rod 23 is slidably installed inside the chute 21. Four springs 24 are equidistantly fixed to the upper surface of the slide rod 23. The connecting frame 25 is fixedly connected to the upper end of the spring 24. The hair roller 26 is rotatably installed inside the connecting frame 25.

[0034] The spring 24 plays a role of buffering and resetting, ensuring stability and continuity during the lubrication process. The connecting frame 25 connects the slide rod 23 and the spring 24 so that they can move synchronously, ensuring the coordination of the lubrication process. The hair roller 26 is responsible for evenly applying the lubricating oil to the mold surface to complete the actual lubrication work.

[0035] The lubrication assembly also includes a support frame 22 and a limit plate 27. The support frame 22 is fixed on both sides of the center of the upper surface of the operating table 11 and is located on both sides of the lower module 16. The limit plate 27 is fixed in the middle of the two support frames 22. A square groove is opened in the center of the limit plate 27. The front side wall of the slide rod 23 is fixedly connected to a handle 28, and the handle 28 is slidably installed in the square groove in the middle of the limit plate 27.

[0036] The limiting plate 27 cooperates with the slide groove 21 to limit the moving range of the slide rod 23 to ensure the accuracy of the lubrication process.

[0037] Working principle:

[0038] Before injection molding, the operator only needs to inject lubricating oil into the connecting frame 25, then hold the handle 28 and drive the handle 28 to move in the square groove of the limit plate 27. At this time, the handle 28 will drive the slide rod 23 to move in the slide groove 21, and synchronously drive the spring 24 to move. When the hair roller 26 contacts the upper module 15, the spring 24 will be compressed downward, and under the elastic force of the spring 24, the hair roller 26 is always in contact with the upper module 15, and the lubricating oil is applied to the surface of the upper module 15. The operation is simple. The operator only needs to inject lubricating oil into the connecting frame 25, and then move the handle 28 to drive the slide rod 23 and the hair roller 26 to complete the lubrication.

[0039] This step, the whole process is simple and clear. By simplifying the lubrication steps, the preparation time before each production can be significantly reduced, thereby improving the overall production efficiency.

[0040] See also Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0041] The cutting assembly includes a mounting slot 31, a circular hole 32, a cutting blade 33, and an electric push rod 34. The mounting slot 31 is provided on the lower surface of the upper module 15, and the circular hole 32 is provided on the upper surface of the upper module 15. The cutting blade 33 is slidably mounted inside the mounting slot 31. The electric push rod 34 is fixedly connected to the upper surface of the cutting blade 33. The output end of the electric push rod 34 passes through the circular hole 32, and the cutting blade 33 moves vertically up and down within the mounting slot 31.

[0042] The mounting groove 31 provides a sliding track for the cutting knife 33, ensuring that the cutting knife 33 can move accurately along the predetermined path. The cutting knife 33 is directly responsible for removing the burrs of the formed product. It moves up and down through the power of the electric push rod 34 to adapt to the edges of products of different thicknesses. The electric push rod 34 is the power source of the entire cutting assembly. Its extension and retraction are controlled by an external controller, thereby driving the cutting knife 33 to perform precise vertical movement.

[0043] Working principle:

[0044] When the upper module 15 is pressed into the lower module 16, after the product is formed, there will be burrs around the product, which needs to be cut flat again. At this time, the staff only needs to use the external controller to control the electric push rod 34 to extend and retract. The output end of the electric push rod 34 extends downward, and at the same time drives the cutting knife 33 to move downward and move out of the installation groove 31. The hydraulic rod 14 presses downward again to make the upper module 15 fit with the lower module 16. At this time, the cutting knife 33 can cut off the excess burrs.

[0045] This step can quickly remove burrs and greatly shorten the total cycle from molding to finished product.
