Description

Technical Field

[0001] This utility model relates to the field of injection mold technology for walkie-talkie housings, and in particular to a positioning and clamping mechanism for injection molds for walkie-talkie housings. Background Technology

[0002] For example, in a walkie-talkie housing injection mold positioning device (application number: 202222345470.4) disclosed on the Chinese Patent website, multiple clamping plates and toothed plates are used to limit the positioning of the injection mold. However, this limiting method has certain drawbacks:

[0003] 1. First, too many clamping plates and toothed plate mechanisms are used, which makes operation very inconvenient. If one mechanism fails, the entire limit device will not work properly, which will increase the failure rate of the entire mechanism.

[0004] 2. Secondly, the entire injection mold cannot be heated while adding injection fluid during injection molding, resulting in low injection efficiency. Utility Model Content

[0005] Based on the existing technical problems of high failure rate and low injection efficiency of injection molds, this utility model proposes a positioning and clamping mechanism for injection molds of walkie-talkie housings.

[0006] This utility model proposes a positioning and clamping mechanism for injection molds of walkie-talkie housings, including a base. The base is provided with a limiting device, which includes a limiting plate, a clamping plate, a spring, and a pull rod. The spring squeezes the clamping plate to make it move within the base. The clamping plate drives the limiting plate to move horizontally, and the pull rod pulls the clamping plate to move horizontally.

[0007] Preferably, a crossbar is fixedly installed on the inner surface of the base, and a first lower mold and a second lower mold are slidably connected to the outer surface of the crossbar, with a connecting plate fixedly installed between the first lower mold and the second lower mold.

[0008] Through the above technical solution, the first and second lower molds are connected together by a connecting plate, so that they can move horizontally synchronously outside the crossbar. This allows one lower mold to be injected while the other is being filled with injection liquid. Similarly, after one is finished, the other can be injected. The lower mold that has finished injection can be unloaded and filled with injection liquid, allowing the two processes to be carried out simultaneously, saving a lot of time and improving injection efficiency.

[0009] Preferably, the outer surfaces of the first lower mold and the second lower mold are provided with slots, and the base is provided with a slot inside, and the card plate is slidably inserted into the slot.

[0010] With the above technical solution, the card plate moves within the card slot, and the slots of the two lower molds are for convenient positioning.

[0011] Preferably, the limiting plate is fixedly installed on the outer surface of the card plate, the outer surface of the limiting plate is slidably connected to the inside of the slot, the spring is fixedly connected to the outer surface of the card plate, and the other end of the spring is fixedly connected to the inside of the card slot.

[0012] Through the above technical solution, the spring squeezes the clamping plate, causing the clamping plate to move and the limiting plate to be inserted into the slot, so that the limiting plate limits the first lower mold and the second lower mold.

[0013] Preferably, the pull rod is fixedly connected to the outer surface of the card plate, the outer surface of the pull rod is slidably connected to the inside of the base, the upper surface of the base is fixedly mounted with a mounting bracket, and the upper surface of the mounting bracket is fixedly mounted with a mounting frame.

[0014] The above technical solution allows the pull rod to be pulled to move the clamping plate, which in turn moves the limiting plate into the base. The mounting bracket and mounting frame facilitate the fixing of the upper mold.

[0015] Preferably, a cylinder is fixedly installed on the inner surface of the mounting frame, an upper mold is fixedly installed on the lower surface of the cylinder rod at the lower end, and a heating plate is fixedly installed on the lower inner side of the base.

[0016] Through the above technical solution, when the cylinder is started, it controls the upper mold to move up and down, so that the upper mold presses down on the lower mold below, and the electric heating plate heats the mold, thereby completing the mold injection.

[0017] The beneficial effects of this utility model are as follows:

[0018] By setting a limiting device, during injection molding, the first and second lower molds slide on a crossbar, while a spring presses a clamping plate, causing the clamping plate to move a limiting plate into the slots of the first and second lower molds, restricting their movement. This allows one of the lower molds to be positioned directly below the upper mold. Then, a cylinder is activated to control the upper mold to press down on the lower mold below, while an electric heating plate heats the mold, thus completing the injection molding. During the injection process, the other lower mold can be filled with injection molding liquid. Similarly, once one mold is finished, the other can be used for injection. The finished lower mold can then be unloaded and filled with injection molding liquid, allowing the two processes to be performed simultaneously, saving a lot of time. Moreover, the overall structure is simple and less prone to failure, achieving the effects of reducing the failure rate and improving injection molding efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-3 A positioning and clamping mechanism for a walkie-talkie housing injection mold includes a base 1. To solve the stability problem of the injection mold and achieve the effect of stable positioning of the injection mold, a limiting device is provided inside the base 1. The limiting device includes a limiting plate 2, a clamping plate 3, a spring 4, and a pull rod 5. The spring 4 squeezes the clamping plate 3 to make the clamping plate 3 move inside the base 1. The clamping plate 3 drives the limiting plate 2 to move horizontally, and the pull rod 5 pulls the clamping plate 3 to move horizontally.

[0025] like Figure 2 and Figure 3 As shown, in order to solve the problem of low injection efficiency of injection molds and achieve the effect of multiple processes being carried out simultaneously, a crossbar 11 is fixedly installed on the inner surface of the base 1. A first lower mold 12 and a second lower mold 13 are slidably connected to the outer surface of the crossbar 11. A connecting plate 14 is fixedly installed between the first lower mold 12 and the second lower mold 13. The first lower mold 12 and the second lower mold 13 are connected together through the connecting plate 14, so that they can move horizontally synchronously outside the crossbar 11. This allows one lower mold to be injected while the other is being injected. Similarly, after one injection is completed, the other can be injected. The lower mold that has been injected can be unloaded and filled with injection liquid, allowing two processes to be carried out simultaneously, saving a lot of time and thus improving injection efficiency.

[0026] like Figure 2 and Figure 3As shown, in order to solve the limiting problem of the first lower mold 12 and the second lower mold 13 and achieve the effect of quickly and easily limiting the lower mold, slots 15 are provided on the outer surfaces of the first lower mold 12 and the second lower mold 13, and slots 16 are provided inside the base 1. The card plate 3 is slidably inserted into the inside of the slot 16 and moves within the slot 16. The slots 15 of the two lower molds are for convenient limiting.

[0027] like Figure 2 and Figure 3 As shown, in order to solve the problem of movement of the limiting plate 2 and achieve the effect of limiting the plate 2 being inserted into the slot 15 for limiting, the limiting plate 2 is fixedly installed on the outer surface of the card plate 3. The outer surface of the limiting plate 2 is slidably connected to the inside of the slot 15. The spring 4 is fixedly connected to the outer surface of the card plate 3. The other end of the spring 4 is fixedly connected to the inside of the card groove 16. The spring 4 squeezes the card plate 3, causing the card plate 3 to drive the limiting plate 2 to move, so that the limiting plate 2 is inserted into the slot 15, allowing the limiting plate 2 to limit the first lower mold 12 and the second lower mold 13.

[0028] like Figure 1 As shown, in order to solve the problem of fixing the upper mold 110 and achieve the effect of injection molding by the upper mold 110 and the lower mold, the pull rod 5 is fixedly connected to the outer surface of the clamping plate 3. The outer surface of the pull rod 5 is slidably connected to the inside of the base 1. The upper surface of the base 1 is fixedly installed with the mounting bracket 17, and the upper surface of the mounting bracket 17 is fixedly installed with the mounting frame 18. Pulling the pull rod 5 can drive the clamping plate 3 to move, so that the clamping plate 3 drives the limiting plate 2 to move into the base 1. The mounting bracket 17 and the mounting frame 18 facilitate the fixing of the upper mold 110.

[0029] like Figure 1 and Figure 3 As shown, in order to solve the mold injection problem and achieve the effect of quickly completing the mold injection, a cylinder 19 is fixedly installed on the inner surface of the mounting frame 18. An upper mold 110 is fixedly installed on the lower surface of the air rod at the lower end of the cylinder 19. An electric heating plate 111 is fixedly installed on the lower inner end of the base 1. When the cylinder 19 is started, it controls the upper mold 110 to move up and down, so that the upper mold 110 presses down on the lower mold below. The electric heating plate 111 heats the mold, thereby completing the mold injection.

[0030] By setting a limiting device, during injection molding, the first lower mold 12 and the second lower mold 13 slide on the crossbar 11, while the spring 4 presses the clamping plate 3, which in turn causes the clamping plate 3 to drive the limiting plate 2 to lock in the slots 15 of the first lower mold 12 and the second lower mold 13, restricting their movement. This allows one of the lower molds to be placed directly below the upper mold 110. Then, the cylinder 19 is activated to control the upper mold 110 to press down on the lower mold below. The heating plate 111 heats the mold, thus completing the injection molding. During the injection molding process, the other lower mold can be filled with injection liquid. Similarly, after one injection is completed, the other can be injected. The lower mold that has been injected can be unloaded and filled with injection liquid, allowing the two processes to be carried out simultaneously, saving a lot of time. Moreover, the overall structure is simple and not prone to failure, achieving the effect of reducing the failure rate and improving injection molding efficiency.

[0031] Working principle: During injection molding, the first lower mold 12 and the second lower mold 13 slide on the crossbar 11, while the spring 4 presses the clamping plate 3, which in turn causes the clamping plate 3 to drive the limiting plate 2 to lock into the slots 15 of the first lower mold 12 and the second lower mold 13, restricting their movement. This allows one of the lower molds to be positioned directly below the upper mold 110. Then, the cylinder 19 is activated to control the upper mold 110 to press down on the lower mold below. The heating plate 111 heats the mold, thus completing the injection molding. During the injection molding process, the other lower mold can be filled with injection liquid. Similarly, after one injection is completed, the other can be injected. The lower mold that has been injected can be unloaded and filled with injection liquid, allowing the two processes to be carried out simultaneously, saving a lot of time. Moreover, the overall structure is simple and not prone to failure.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
