Technical Field

[0001] This utility model relates to the field of antenna housing injection mold technology, specifically to an injection mold for an antenna housing. Background Technology

[0002] The injection mold for antenna housing is a specialized tool system used for the large-scale, high-precision production of antenna plastic housings. It injects molten plastic at high temperature into the mold cavity, and after cooling and shaping, it forms an antenna housing that meets the electromagnetic performance requirements.

[0003] The aforementioned device lacks a structure for quick disassembly and assembly of the cooling water port of the injection mold during use. As a result, the cooling water port of the existing injection mold is mostly connected to the external pipeline using a nut connection. Although this connection has a good effect, it requires the use of corresponding tools for disassembly and assembly. Moreover, after repeated disassembly, assembly, maintenance and repair, the threads inside the nut are very easy to strip, affecting the fixing effect and sealing performance. Based on the shortcomings of the existing technology, this utility model designs an injection mold for antenna housing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an injection mold for an antenna housing, which has the advantage of quick assembly and disassembly of the cooling water port of the injection mold.

[0012] As a preferred embodiment of this utility model, the limiting rod is slidably inserted into the limiting hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This injection mold for an antenna housing involves holding the locking cover and pushing it backward, causing the inner ring to move backward and compressing the traction spring. Then, the two clips at the front end of the connector are kept in a horizontal position and aligned with the gap between the two locking plates. The connector and clips are inserted onto the inlet / outlet water connector and the sealing ring, with the clips passing between the two locking plates. At this point, the connector and the inlet / outlet water connector are sealed. Rotating the connector then causes the clips to rotate and engage with the locking plates for locking. Finally, releasing the locking cover allows the traction spring to push the inner ring, causing the locking cover to move outward. This allows the first and second inserts, fixedly connected to the inner wall of the locking cover, to engage with the notch and side groove of the locking plate, respectively, limiting the connection of the connector and clips. This device facilitates quick connection of the inlet / outlet water connector and the water supply pipe. Attached Figure Description

[0017] Please see Figure 1-5 An injection mold for an antenna housing includes an upper mold 1, a lower mold 101 on the lower surface of the upper mold 1, cooling pipes 105 on the upper mold 1 and the lower mold 101, water inlet and outlet connectors 2 fixedly connected to the water inlet and outlet ends of the cooling pipes 105, a connection mechanism 3 for quick locking with external pipes on the water inlet and outlet connectors 2, a limiting rod 102 fixedly connected to the lower surface of the upper mold 1, a limiting hole 103 on the upper surface of the lower mold 101, an injection hole 104 on the top of the upper mold 1, and the limiting rod 102 slidably inserted into the limiting hole 103.

[0018] Please see Figure 5 The connecting mechanism 3 includes a locking plate 301, a sealing ring 302, a connector 303, a clamp 304, a water supply pipe 305, and a side groove 306. The locking plate 301 is fixedly connected to the outer surface of the inlet / outlet connector 2. The sealing ring 302 is fixedly connected to the outer surface of the inlet / outlet connector 2. The connector 303 is inserted into the inlet / outlet connector 2. The clamp 304 is fixedly connected to the side of the connector 303 facing the inlet / outlet connector 2. The water supply pipe 305 is fixedly connected to the outer end of the connector 303. The side groove 306 is formed on the side wall of the connector 303. The clamp 304 is rotatably clamped onto the locking plate 301. The sealing ring 302 is disposed between the inlet / outlet connector 2 and the connector 303. By setting a sealing ring 302, a connector 303, and a water supply pipe 305, the water supply pipe 305 is sealed to the inlet and outlet water connector 2, thereby realizing the inlet and outlet water flow of the cooling pipe 105. By setting a locking plate 301 and a clamp 304, the connector 303 can be locked by rotation with the inlet and outlet water connector 2. By setting a side groove 306, it is limited and locked by the second insert block 206.

[0019] Please see Figure 4 A baffle 201 is fixedly connected to the inlet / outlet water connector 2. A lock cover 202 is sleeved on the inlet / outlet water connector 2. A movable inner groove 203 is provided inside the lock cover 202. An inner ring 204 is fixedly connected to the inner wall of the inlet / outlet water connector 2. A first insert 205 is fixedly connected to the inner wall of the inlet / outlet water connector 2. A second insert 206 is fixedly connected to the inner wall of the inlet / outlet water connector 2. A traction spring 207 is provided inside the movable inner groove 203. The first insert 205 is slidably inserted into the gap between the two lock plates 301. The second insert 206 is slidably inserted into the side groove 306. The baffle 201 is located inside the movable inner groove 203. The traction spring 207 is located between the baffle 201 and the inner ring 204.

[0020] By setting up a locking cover 202, a first insert 205, and a second insert 206, the connector 303 and the clamp 304 inserted into the inlet / outlet water connector 2 are limited and locked to prevent the connector 303 from rotating and disengaging due to other forces. By setting up a baffle 201, a movable inner groove 203, an inner ring 204, and a traction spring 207, the locking cover 202 can cover the connector 303 for a long time to lock it.

[0021] Working principle: When an injection mold for an antenna housing is used, in the initial state, the lower mold 101 is first set below the upper mold 1. Limiting rods 102 and limiting holes 103 are set on the opposing sides of the upper mold 1 and the lower mold 101. An injection hole 104 is set on the top of the upper mold 1 to facilitate injection molding. The inlet and outlet ends of the cooling pipe 105 opened on one side of the upper mold 1 are connected to water inlet and outlet connectors 2. The locking plate 301 and sealing ring 302 fixedly connected to the water inlet and outlet connectors 2 are connected to the connector 303 and the clamp 304. A water supply pipe 305 is installed on the outer end of the connector 303 to facilitate the quick connection of the water supply pipe 305 to the water inlet and outlet connectors 2 and the cooling pipe 105 to control the temperature of the upper mold 1 and the lower mold 101. When it is necessary to quickly connect the inlet / outlet water connector 2 and the water supply pipe 305, first hold the lock cover 202 and push it backward to move the inner ring 204 backward and compress the traction spring 207. Then, keep the two clips 304 at the front end of the connector 303 in a horizontal position and align them with the gap between the two lock plates 301. Insert the connector 303 and clips 304 onto the inlet / outlet water connector 2 and the sealing ring 302, and let the clips 304 pass between the two lock plates 301. At this time, the connector 303 and the inlet / outlet water connector 2 are in a sealed state. Then, rotate the connector 303 to drive the clamp 304 to rotate and clamp onto the lock plate 301 for locking. Finally, release the lock cover 202 so that the traction spring 207 pushes the inner ring 204 to move the lock cover 202 outward. This allows the first insert 205 and the second insert 206, which are fixedly connected to the inner wall of the lock cover 202, to be respectively inserted into the notch of the lock plate 301 and the groove of the side groove 306 to limit the connector 303 and the clamp 304. This device facilitates the quick connection of the inlet / outlet water connector 2 and the water supply pipe 305.
