[0020] 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.

[0021] Example

[0022] Please see Figs. 1-3 This embodiment provides the following technical solution: a flow meter lining injection mold, including a mold body 1 and a mold core 2. The mold core 2 is disposed inside the mold body 1. The inner wall of the mold body 1 and the outer wall of the mold core 2 cooperate to form an injection cavity 3. An injection hole 4 communicating with the injection cavity 3 is disposed in the middle of the mold body 1. The injection hole 4 disposed in the middle of the mold body 1 replaces the traditional method of injection from the end, which improves the flow rate of the injection material and avoids the problem of uneven temperature caused by low flow rate of injection material. This improves the filling efficiency of the injection material and avoids the problems of difficult filling and poor filling effect of injection material.

[0023] The outer sides of both the upper and lower ends of the mold body 1 are fixedly fitted with mold covers 5. The mold body 1 and the mold covers 5 are integrally formed and are arranged in an "I" shape.

[0024] The mold core 2 is provided with a core cover 6 at both the upper and lower ends. The side of the core cover 6 facing each other is provided with a receiving cavity 7 that is compatible with the mold cover 5. The core cover 6 and the mold cover 5 work together to form a sealing structure of the injection cavity 3. Through the provided core cover 6, after the mold core 2 is put into the mold body 1, the upper and lower ends of the injection cavity 3 can be sealed, so that the injection cavity 3 can form a sealed space for injection molding of the flow meter liner.

[0025] In some embodiments, both the mold core 2 and the core cover 6 are provided with mutually compatible positioning holes 8. The mold core 2 and the core cover 6 are fixed together by bolts threaded to the positioning holes 8. The bolts facilitate the installation and removal of the core cover 6 onto the mold core 2, which not only seals the injection cavity 3 but also allows the injection cavity 3 to be in an open state for removing the injection-molded flow meter liner. Furthermore, the mold core 2 can be replaced as needed.

[0026] In some embodiments, the mold core 2 and the upper and lower end caps 6 are assembled into an "I" shaped structure.

[0027] The outer diameter of the core cover 6 is larger than that of the mold cover 5, which can fix the mold body 1 and the mold cover 5 between the upper and lower core covers 6, so that the mold body 1, the mold cover 5, the mold core 2 and the core cover 6 work together to form an integral injection mold, thereby moving the device and making it easy to place the device on the injection molding equipment or remove it from the injection molding equipment.

[0028] Two clamping discs 9 are also fixedly fitted on the outer side of the mold body 1. The two clamping discs 9 are located between the two mold covers 5. The two clamping discs 9 work together to form a clamping cavity. The two clamping discs 9 make it easy to install and fix the device on the injection molding equipment. When the injection molding equipment is fixed, the flow meter lining can be injection molded.

[0029] The working principle of the utility model discloses: when using, first, one of the core covers 6 is fixed on one end of the mold core 2 through the bolt, then the mold core 2 is inserted from one end of the mold body 1, and the other core cover 6 is fixed on the other end of the mold core 2 through the bolt, after the fixing of the core cover 6 on the mold core 2 is completed, the mold cover 5 is located in the corresponding accommodating cavity 7, thereby the sealing of the injection cavity 3 is completed;

[0030] Then move the injection mold, move the injection mold to the injection equipment, and fix the injection mold through the clamping tool on the injection equipment, and the injection hole 4 on the mold body 1 is correspondingly arranged with the injection nozzle on the clamping tool, so that the injection equipment can be driven, the injection raw material is injected into the injection hole 4 through the injection nozzle, and the injection raw material flows from the middle of the injection cavity 3 to both ends of the injection cavity 3, thereby the rapid injection of the flowmeter liner is completed.

[0031] Finally, it should be noted that: the above only for the preferred embodiments of the utility model have been described, and are not used to limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features.
