Description

Technical Field

[0001] This utility model relates to the field of injection molding mechanism technology, and more specifically, it relates to an injection molding mechanism for processing sensor housings. Background Technology

[0002] A sensor (English name: transducer / sensor) is a detection device that can sense the information being measured and transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording and control. The existence and development of sensors have given objects senses such as touch, taste and smell, making objects come alive. Sensors are an extension of human senses. Sensors have the characteristics of miniaturization, digitization, intelligence, multi-functionality, systematization and networking. They are the primary link in realizing automatic detection and automatic control.

[0003] Currently, sensor housings require injection molding during manufacturing. However, the current injection molding mechanism requires different molding cavities due to the different sensor housings. Currently, bolts are usually used for fixing, which makes disassembly and assembly difficult. Moreover, there is no protective mechanism during mold closing, which can easily cause wear at the mold closing point. Furthermore, the production efficiency of injection molds is reduced because they cannot be cooled quickly. Therefore, there is a need for an injection molding mechanism for processing sensor housings. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides an injection molding mechanism for processing sensor housings, which has the following advantages:

[0017] 1. By opening the sealed door, pull the lever to one side to move the slide plate, which in turn moves the trapezoidal block. Remove the trapezoidal block from the slot, and then remove the cavity through the groove and protrusion, and through the handle groove for replacement.

[0031] Specifically, by opening the sealing door 8, pulling the lever 15 to one side moves the slide plate 10, which in turn moves the trapezoidal block 12. The trapezoidal block 12 is then removed from the slot 13. The cavity 6 is then removed and replaced through the groove 4 and protrusion 5 and the handle groove 14. The new cavity 6 is then installed into the mounting base 3. The elasticity of the first spring 11 moves the slide plate 10 and the trapezoidal block 12, causing the trapezoidal block 12 to engage and fix with the slot 13, facilitating the replacement of the cavity 6.

[0032] Please see Figures 1-6 A support rod 16 is fixedly connected to the upper surface of the lower mold base 2. The upper surface of the support rod 16 is fixedly connected to the upper mold base 1. A hydraulic cylinder 17 is fixedly installed on the upper surface of the upper mold base 1.

[0036] In summary, when using the overall equipment:

[0037] First, the hydraulic cylinder 17 is activated to move the mounting plate 18 up and down, closing the lower mold base 2. During mold closing, the movable rod 19 slides within the mounting plate 18. The elasticity of the second spring 21 reduces the impact force during mold closing, increasing protection and preventing damage to the mold. Then, the fan 23 is activated, and the cooling mechanism 27 cools the water in the water tank 26. The mounting pipe 24, installed inside the water tank 26, is cooled by the cooled water. Air passes through the cooling pipe 24 and enters the funnel 28, where it passes through the filter screen 29 to remove impurities. The filtered and cooled air cools the bottom of the mounting base 3, facilitating rapid cooling of the mold and increasing production efficiency. When changing the cavity 6, the sealing door 8 is opened, and the pull rod 15 is pulled to one side to move the slide plate 10, which in turn moves the trapezoidal locking block 12. The trapezoidal locking block 12 is then removed from the slot 13. The cavity 6 is then removed through the groove 4 and the protrusion 5, and through the handle groove 14 for replacement. The new cavity 6 is then installed inside the mounting base 3. The elasticity of the first spring 11 moves the slide plate 10 and the trapezoidal locking block 12, causing the trapezoidal locking block 12 to engage and fix with the slot 13, facilitating the replacement of the cavity 6.
