Description

Technical Field

[0001] This utility model relates to the technical field of sensors, and in particular to a shaping device for a sensor housing. Background Technology

[0002] A sensor is a device that senses and detects physical, chemical, or biological signals in the environment and converts them into usable electrical signals or other forms of output to meet the requirements of information transmission, processing, storage, display, recording, and control. It plays a "sensory" role in modern technology and is widely used in industries such as manufacturing, medicine, consumer electronics, and environmental monitoring.

[0003] Currently, when using silicone encapsulation for sensors, operators typically place the sensor into a mold, then pour molten silicone into the mold. After the silicone solidifies, a silicone shell is then encapsulated on the sensor. However, this method requires a long time to solidify, resulting in low production efficiency. Utility Model Content

[0004] To improve efficiency, this utility model provides a shaping device for sensor housings to address the problems of the prior art.

[0005] The present invention provides a shaping device for a sensor housing, which adopts the following technical solution:

[0006] A molding device for a sensor housing includes a base, on which a first mold is fixedly mounted, and on which a second mold is slidably mounted. A first half-groove is formed on the surface of the first mold, and a second half-groove is formed on the surface of the second mold. The first mold and the second mold are fitted together, and the first half-groove and the second half-groove together form a pouring groove. A driving component is provided on the base to drive the second mold closer to the first mold and further away from the first mold. Both the first mold and the second mold have flow channels inside. Water pipe connectors are connected to the sides of both the first mold and the second mold, and the water pipe connectors are connected to the flow channels.

[0007] Preferably, the driving component includes a driving cylinder disposed on the base, the piston rod of the driving cylinder is connected to a slider, and the slider is fixedly connected to the first mold.

[0008] Preferably, fixing plates are provided on opposite sides of the slider, and the fixing plates are threadedly connected to the second mold with screws.

[0009] Preferably, the base is provided with two parallel guide rails, which are arranged along the axial length direction parallel to the drive cylinder, and the guide rails are movably connected to the slider.

[0010] Preferably, the base is provided with a fastening plate, and the fastening plate is threadedly connected to the first mold with bolts.

[0011] Preferably, the base is provided with a wire-locking block, which is located directly above the first mold and the second mold, and the wire-locking block is provided with a wire-locking groove.

[0012] Preferably, the first mold and the second mold have multiple injection grooves, and the multiple injection grooves are spaced apart along the length direction of the first mold.

[0013] In summary, the present invention includes at least one of the following beneficial technical effects of a sensor housing shaping device:

[0014] The operator places the sensor into the injection tank, clips the sensor wires onto the wire slots of the wire clip block, and then fills the injection tank with silicone. Meanwhile, cold water flows into the first and second molds through the water pipe connector, which quickly cools the silicone. Then, the piston rod of the drive cylinder retracts, causing the second mold to separate from the first mold, making it easy for the operator to remove the sensor. The entire production process is convenient and fast, improving the sensor packaging efficiency. Attached Figure Description

[0019] 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.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] This utility model discloses a shaping device for a sensor housing, such as... Figs. 1-3 As shown, the device includes a base 1, a first mold 2 is provided on the upper surface of the base 1, the bottom side of the first mold 2 is attached to the upper surface of the base 1, a fastening plate 12 is fixedly installed on the base 1, the fastening plate 12 is attached to one side surface of the first mold 2, and a bolt is threadedly connected between the fastening plate 12 and the first mold 2.

[0022] Meanwhile, a second mold 3 is slidably connected to the base 1. One side surface of the first mold 2 is in contact with the surface of the second mold 3 facing away from the fastening plate 12. Multiple first semi-grooves 21 are formed on the surface of the first mold 2 facing the second mold 3, with the top of each semi-groove 21 penetrating the top of the first mold 2. In this embodiment, the number of first semi-grooves 21 is preferably five. Multiple second semi-grooves 31 are formed on the surface of the second mold 3 facing the first mold 2. In this embodiment, the number of second semi-grooves 31 is preferably five. The five second semi-grooves 31 correspond to the five first semi-grooves 21. When the first mold 2 and the second mold 3 are in contact, the five first semi-grooves 21 and the five second semi-grooves 31 together form five injection grooves 22. The five injection grooves 22 are spaced apart along the length of the first mold 2. When encapsulating the sensor, the operator places the sensor into the injection groove 22, and then pours molten silicone into the injection groove 22. After the silicone cools and solidifies, a shell can be encapsulated on the sensor.

[0023] Meanwhile, the base 1 is equipped with a driving component that drives the second mold 3 closer to the fire and away from the first mold 2. Specifically, the driving component includes a driving cylinder 5 fixedly mounted on the base 1 in a horizontal direction. The piston rod of the driving cylinder 5 is fixedly connected to a slider 51. Fixing plates 511 are welded to opposite sides of the slider 51. The fixing plates 511 are in contact with the surface of the second mold 3 away from the first mold 2. The fixing plates 511 are threadedly connected to the second mold 3 with screws. At the same time, two parallel guide rails 11 are fixedly mounted on the base 1. The guide rails 11 are arranged parallel to the axial length of the driving cylinder 5 and are movably connected to the slider 51. The guide rails 11 movably pass through the first mold 2 and the second mold 3. When the piston rod of the driving cylinder 5 extends, it drives the second mold 3 to approach and fit against the first mold 2, thereby enclosing the first half-groove 21 and the second half-groove 31. After the piston rod of the driving cylinder 5 retracts, it drives the second mold 3 to disengage from the first mold 2, which facilitates the operator to remove the sensor. Meanwhile, guide posts 24 are welded to the four corners of the surface of the first mold 2 facing the second mold 3. The guide posts 24 move through the second mold 3, and the guide posts 24 can make the docking between the first mold 2 and the second mold 3 more precise.

[0024] In addition, both the first mold 2 and the second mold 3 have flow channels inside. Both the first mold 2 and the second mold 3 have two water pipe connectors 4 connected to their sides. One water pipe connector 4 is connected to the water inlet of the flow channel, and the other water pipe connector 4 is connected to the water outlet of the flow channel. The water pipe connector 4 can be connected to an external water supply pipe to supply water to the flow channel, which can cool the first mold 2 and the second mold 3, thereby allowing the silicone to cool down quickly. In addition, a wire-clamping block 13 is provided on the base 1. The wire-clamping block 13 is welded to the fastening plate 12. The wire-clamping block 13 is located directly above the first mold 2 and the second mold 3. Six wire-clamping slots 131 are opened on the side of the wire-clamping block 13. The six wire-clamping slots 131 correspond to the positions of the six injection slots 22 respectively. The wire-clamping slots 131 and the injection slots 22 are coaxially arranged. Since there are wires connected to the sensing line, the sensor is lifted by clamping the wires into the wire-clamping slots 131. This makes it difficult for the sensor to touch the inner wall of the injection slot 22, so that part of the sensor is exposed outside the silicone shell after silicone encapsulation.

[0025] The implementation principle of the sensor housing shaping device of this utility model embodiment is as follows: the piston rod of the drive cylinder 5 extends, driving the second mold 3 to approach and fit against the first mold 2, thereby enclosing the first half-groove 21 and the second half-groove 31 to form a filling groove 22. Then, the operator places the sensor into the filling groove 22 and clamps the sensor wire onto the wire clamping groove 131 of the wire clamping block 13. Then, silicone is poured into the filling groove 22, while cold water flows into the first mold 2 and the second mold 3 through the water pipe connector 4, thereby rapidly cooling the silicone. Then, the piston rod of the drive cylinder 5 retracts, driving the second mold 3 to separate from the first mold 2, making it convenient for the operator to remove the sensor. The whole production process is convenient and fast, improving the packaging efficiency of the sensor.
