A PVC louver blade injection molding device

Abstract

This utility model discloses a PVC louver blade injection molding device, belonging to the field of louver blade molding technology. It includes a worktable with two uprights fixedly connected to its top. Electric telescopic rods are fixedly installed on each of the two uprights, and injection molds are mounted on the output ends of both electric telescopic rods. Multiple combined cavity grooves are provided on the inner sides of both injection molds. In this utility model, when the two injection molds are closed, the ends of the push rods on the two injection molds abut against the inner cavity of the sliding hole and retract, simultaneously causing the ends of the push rods to retract into the inner cavity of the movable hole. When louver blades are injection molded in the combined cavity grooves, the two electric telescopic rods move the two injection molds away from each other. At this time, the restoring force of the spring drives the connecting plate, push rod, and push rod to move, causing the ends of the push rods to push the louver blades formed in the combined cavity grooves out, ensuring that the injection-molded louver blades can fall smoothly. This device is highly practical.

Description

Technical Field

[0001] This utility model relates to the field of louver blade molding technology, and more specifically, to a PVC louver blade injection molding device. Background Technology

[0002] Venetian blinds are installed on windows and are generally used for indoor and outdoor sun shading and ventilation. Unlike the soft texture of curtains, Venetian blind slats are usually made of materials such as wood, glass, and aluminum alloy, making them resistant to sunlight, wind, rain, and dust, and easy to clean. Modern young people prefer lightweight and simple styles when decorating their homes, so more and more Venetian blinds made of plastic are appearing on the market. Plastic Venetian blinds are not only lightweight but also easy to clean, making them increasingly popular among young people.

[0003] PVC louver blades are generally manufactured by injection molding. However, existing louver blades are not easy to cut after being formed in the injection mold, and the cut louver blades are not easy to collect. Therefore, we propose a PVC louver blade injection molding device. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a PVC louver blade injection molding device.

[0005] To solve the above problems, the present invention adopts the following technical solution:

The ends of the push rods are movably sleeved into the inner cavities of the sliding holes. A material receiving mechanism is provided on the worktable.

[0007] As a preferred embodiment of this utility model, the receiving mechanism includes a support frame fixedly connected to the top surface of the workbench and an L-shaped bracket fixedly connected to the bottom surface of the workbench. A slide is fixedly connected to the top of the support frame, and a placement groove is provided on the L-shaped bracket. A receiving box is placed in the inner cavity of the placement groove, and a moving block is provided at both ends of the receiving box.

[0008] As a preferred embodiment of this utility model, a cooling groove is provided inside the injection mold, and pipe sleeves are provided at both ends of the cooling groove and on the side of the injection mold.

[0013] The advantages of this utility model are:

[0014] (1) In this utility model, when the two injection molds are closed, the ends of the push rods on the two injection molds abut against the inner cavity of the sliding hole and retract, while the end of the push rod retracts into the inner cavity of the movable hole. When the louver blades are injection molded in the combined cavity, the two injection molds are driven away from each other by the two electric telescopic rods. At this time, the restoring force of the spring drives the connecting plate, push rod and push rod to move, so that the end of the push rod pushes the louver blades formed in the inner cavity of the combined cavity to be pushed out, ensuring that the injection molded louver blades can fall off smoothly, which is practical.

[0015] (2) In this utility model, by using the support frame, L-shaped bracket, slide and receiving box together, the louver blades falling from the two injection molds are caught by the slide, so that the louver blades slide from the slide to the inner cavity of the receiving box for collection, thus realizing the function of collecting the injection molded louver blades, which is practical.

Electric telescopic rods 3 are fixedly installed on the two uprights 2. Injection molds 4 are installed at the output ends of the two electric telescopic rods 3. Multiple combined cavity grooves 5 are provided on the inner side of the two injection molds 4. Combined injection tubes 6 are fixedly sleeved on the inner side of the multiple injection molds 4 and located above the combined cavity grooves 5. Movable grooves 7 are provided inside the two injection molds 4. Movable holes 8 are provided on the inner wall of the multiple combined cavity grooves 5. Sliding holes 9 are provided on the inner side of the injection molds 4. Springs 10 are fixedly connected to the inner wall of the movable grooves 7. Connecting plates 11 are fixedly connected to the ends of the springs 10. Multiple push rods 13 are fixedly connected to the connecting plates 11. The ends of the multiple push rods 13 are movably sleeved into the inner cavity of the movable holes 8. Push rods 12 are fixedly connected to the connecting plates 11. The ends of the push rods 12 are movably sleeved into the inner cavity of the sliding holes 9. A receiving mechanism 26 is provided on the workbench 1.

[0028] In this embodiment, when the inner surfaces of the two injection molds 4 are in contact, the ends of the push rods 12 inside the two injection molds 4 abut against the inner cavity of the sliding hole 9. At the same time, the push rods 12 drive the connecting plate 11 and the movable hole 8 to move, so that the end face of the movable hole 8 is flush with the inner wall of the combined cavity 5, ensuring that the combined cavity 5 on the side of the two injection molds 4 forms a cavity for injection molding.

[0029] For details, please refer to Figure 1 and Figure 2 The receiving mechanism 26 includes a support frame 14 fixedly connected to the top surface of the workbench 1 and an L-shaped bracket 15 fixedly connected to the bottom surface of the workbench 1. A slide 16 is fixedly connected to the top of the support frame 14. A placement groove 17 is provided on the L-shaped bracket 15. A receiving box 18 is placed in the inner cavity of the placement groove 17. Moving blocks 19 are provided at both ends of the receiving box 18.

[0030] In this embodiment, the slide 16 is used to catch the louver blades that fall from the injection mold 4, and the receiving box 18 is used to catch the louver blades that slide off the slide 16.

[0031] For details, please refer to Figure 5 The injection mold 4 has a cooling groove 24 inside, and pipe sleeves 25 are provided at both ends of the cooling groove 24 and on the side of the injection mold 4.

[0032] In this embodiment, the two connecting sleeves 25 are respectively connected to the external water inlet pipe and water outlet pipe, and the circulating water in the inner cavity of the cooling tank 24 is used to cool the injection mold 4.

[0033] For details, please refer to Figure 2 and Figure 3The electric telescopic rod 3 has a fixing hole 21 on the side of its output end. An installation sleeve 22 is fixedly connected to the outside of the injection mold 4. The output end of the electric telescopic rod 3 is movably sleeved into the inner cavity of the installation sleeve 22. A bolt 23 is threaded onto the installation sleeve 22 and passes through the inner cavity of the fixing hole 21.

[0034] In this embodiment, the injection mold 4 is installed on the electric telescopic rod 3 by the cooperation of the fixing hole 21, the mounting sleeve 22 and the bolt 23.

[0035] For details, please refer to Figure 4 The inner diameter of the movable hole 8 is equal to the outer diameter of the push rod 13, and the outer diameter of the push rod 12 is equal to the inner diameter of the sliding hole 9.

[0036] In this embodiment, the push rod 13 is located in the inner cavity of the movable hole 8 to block the inner cavity of the movable hole 8, thereby preventing the injection liquid in the inner cavity of the combined cavity groove 5 from entering the inner cavity of the movable hole 8. In addition, the stability of the push rod 12 located in the inner cavity of the sliding hole 9 is ensured.

[0037] For details, please refer to Figure 1 and Figure 2 The inner wall of the placement groove 17 fits against the side of the receiving box 18.

[0038] In this embodiment, the stability of the receiving box 18 placed in the inner cavity of the placement slot 17 is ensured.

[0039] For details, please refer to Figure 1 A control panel 20 is fixedly installed on the outside of a support frame 2, and the control panel 20 is electrically connected to the electric telescopic rod 3.

[0040] In this embodiment, the electric telescopic rod 3 is controlled by the control panel 20, and the control panel 20 and the electric telescopic rod 3 are powered by the power supply of the external device.

[0041] Working principle: In use, the two electric telescopic rods 3 first drive the two injection molds 4 to approach the mold closing position. During the mold closing process, the ends of the push rods 12 inside the two injection molds 4 abut against each other, and the push rods 12 retract into the inner cavity of the sliding hole 9. At the same time, the push rods 12 drive the connecting plate 11 and the push rod 13 to move, and the spring 10 is stretched, so that the end of the push rod 13 retracts into the inner cavity of the movable hole 8. The end of the push rod 13 is flush with the inner wall of the combined cavity groove 5, and the side of the connecting plate 11 is in contact with the inner wall of the movable groove 7. At the same time, the combined cavity groove 5 inside the two injection molds 4 forms the injection cavity, and the combined injection tubes 6 at the top of the two injection molds 4 combine into one injection mold. The tube is then injected into the cavity of the combined cavity 5 using the injection head of the external injection molding equipment. This forms louver blades in the cavity 5. After the louver blades in the cavity 5 are formed, the two electric telescopic rods 3 are activated to move the two injection molds 4 away from each other. At the same time, the restoring force of the spring 10 moves the connecting plate 11, the push rod 12, and the push rod 13. This causes the end of the push rod 13 to push the louver blades formed in the cavity 5 out, so that the louver blades fall onto the slide 16. Finally, the louver blades on the slide 16 slide into the cavity of the receiving box 18 and are collected.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
