Description

Technical Field

[0001] This utility model relates to the field of injection mold technology for isolation sleeves, specifically to the injection molding structure of an isolation sleeve for a fluoroplastic magnetic pump. Background Technology

[0002] The isolation sleeve in a fluoroplastic magnetic pump is a key component, which is usually manufactured by injection molding. However, the existing injection molding structure of the isolation sleeve has some problems. It requires manual disassembly during demolding, which is inconvenient. Moreover, external force needs to be applied to the outside of the mold during injection molding to prevent the upper and lower molds from detaching during the injection process, thus increasing the efficiency of subsequent disassembly and sampling. Utility Model Content

[0003] The purpose of this invention is to provide an injection-molded structure for a fluoroplastic magnetic pump isolation sleeve, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fluoroplastic magnetic pump isolation sleeve injection molding structure, including a lower mold, a semi-circular slot in the middle of the lower mold, an annular groove at the edge of the lower mold, symmetrically arranged magnetic L-shaped arc blocks movably inserted in the semi-circular slot, the upper ends of the L-shaped arc blocks being fixedly connected to an upper mold, sliding rods being fixedly connected to both sides of the lower end of the upper mold, the lower ends of the sliding rods being slidably connected in the annular groove, and movable holes being fixedly connected to both sides of the bottom end of the lower mold, with push plates slidably connected in each movable hole.

[0005] Preferably, the inner walls of both the lower and upper molds used for injection molding are fixedly connected with protective layers.

[0006] Preferably, an injection port is provided through one side of the upper end of the upper mold.

[0007] Preferably, magnetic plates are fixedly connected to the opposite side walls of the semi-circular slot, and the magnetic plates and L-shaped arc blocks are arranged correspondingly.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by setting an annular groove and a sliding shell to rotate stably when the upper mold and the lower mold are closed, the L-shaped arc block at the lower end of the upper mold moves inside the semi-arc slot until the L-shaped arc block and the magnetic plate inside the semi-arc slot are magnetically connected, which increases the overall limiting stability and facilitates subsequent injection molding. At the same time, in conjunction with the movable hole and push plate at the bottom end, the isolation sleeve can be quickly pushed after injection molding, increasing the demolding speed.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a fluoroplastic magnetic pump isolation sleeve injection molding structure, including a lower mold 1, a semi-arc slot 2 in the middle of the lower mold 1, an annular groove 3 at the edge of the lower mold 1, symmetrically arranged magnetic L-shaped arc blocks 4 movably inserted in the semi-arc slot 2, the upper ends of the L-shaped arc blocks 4 are fixedly connected to an upper mold 5, the lower ends of the upper mold 5 are fixedly connected to both sides of the lower end of the upper mold 5, the lower ends of the slide rods 9 are slidably connected in the annular groove 3, the lower ends of the lower mold 1 are fixedly connected to both sides of the bottom end of the lower mold 1, and push plates 8 are slidably connected in the movable holes 7, the inner walls of the lower mold 1 and the upper mold 5 for injection are fixedly connected to a protective layer, an injection port 6 is opened through one side of the upper end of the upper mold 5, and magnetic plates are fixedly connected to the opposite side of the groove wall of the semi-arc slot 2, and the magnetic plates and L-shaped arc blocks 4 are correspondingly arranged.

[0017] Specifically, when using this utility model, if the isolation sleeve needs to be injection molded, the lower mold 1 is first stably supported by the external bracket, and then the slide rod 9 is stably inserted into the annular groove 3 by the upper mold 5. At the same time, as the upper mold 5 descends, the upper mold 5 will drive the L-shaped arc block 4 to be stably inserted into the semi-arc slot 2. At this time, the upper mold 5 is rotated, and under the force and the sliding limit action of the annular groove 3 and the slide rod 9, the upper mold 5 stably drives the L-shaped arc block 4 to rotate and be inserted into the semi-arc slot 2 until it is magnetically connected with the magnetic block of the inner wall of the semi-arc slot 2. At this time, the upper mold 5 and the lower mold 1 are closed and installed. Then, the solution to be injected is injected into the mold groove inside the upper mold 5 and the lower mold 1 through the injection port 6. After the injection is completed, the upper mold 5 is removed, and then the push plate 8 is pushed. The push plate 8 pushes the isolation sleeve through the movable hole 7 for convenient and quick demolding.
