Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for a vehicle radar cover. Background Technology

[0002] Automotive radar systems are typically used in autonomous or driver assistance systems, so their covers need to have high wave transmittance to avoid interfering with radar signals, while also possessing good weather resistance, mechanical strength, and sealing properties. The production of these covers involves injection molding using molds, and after the molds are assembled, they need to be locked in place to ensure mold stability during production. Currently, locking these molds often requires manual operation, which is cumbersome and hinders production efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide a vehicle radar cover mold that allows for convenient and quick self-locking and unlocking of the mold.

[0004] To achieve the above objectives, this utility model proposes a vehicle radar cover mold, comprising:

[0005] A mold base, comprising an upper mold and a lower mold, wherein the mating surfaces of the upper mold and the lower mold are respectively provided with a concave mold portion and a convex mold portion;

[0006] Two self-locking structures are respectively disposed on the opposite sides of the mold base. Each self-locking structure includes a connector and a locking component. The connector is disposed on the edge of the upper mold and has a connector portion facing the lower mold. The locking component is disposed on the edge of the lower mold and has a movable connector groove corresponding to the connector portion. The connector portion and the movable connector groove can be engaged and limited.

[0007] In one embodiment of the present invention, the locking assembly includes a first connecting seat and two back-to-back abutting members. The abutting members are rotatably connected to the first connecting seat. The two abutting members have arc-shaped surfaces on their facing sides, and the two arc-shaped surfaces together form the movable insertion groove.

[0008] In one embodiment of the present invention, the abutting member is provided with a pressure plate on the side opposite to the arc-shaped surface, and a spring is provided between the pressure plate and the first connecting seat.

[0009] In one embodiment of the present invention, the plug-in component includes a second connector and a support plate vertically disposed on the surface of the second connector, wherein the end of the support plate has a cylindrical structure to form the plug-in portion.

[0010] In one embodiment of this utility model, the upper mold and the lower mold are respectively provided with grooves and bosses at the corners of the mating surfaces, the bosses are provided with positioning posts, and the grooves are provided with positioning holes corresponding to the positioning posts.

[0011] This invention employs a self-locking structure at the connection between the upper and lower molds. When the molds are fitted together, the insert part presses against the curved surface, causing the pressure plate to compress the spring. The insert part then extends into the movable insert groove. The spring then rebounds, pressing against the pressure plate and driving the curved surface to press firmly against the insert part, thus locking the molds. When it is necessary to separate the molds, a greater pulling force is applied, causing the insert part to press against the curved surface again. The pressure plate compresses the spring, and the insert part moves out of the movable insert groove, allowing the molds to be separated. This design enables convenient and quick self-locking and unlocking of the molds. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] Reference Figures 1 to 2This utility model proposes a vehicle radar cover mold, including a mold base and two self-locking structures. The mold base includes an upper mold 1 and a lower mold 2. The mating surfaces of the upper mold 1 and the lower mold 2 are respectively provided with a concave mold portion and a convex mold portion 21. The two self-locking structures are respectively provided on the opposite sides of the mold base. The self-locking structure includes a plug-in 3 and a locking component 4. The plug-in 3 is provided on the edge of the upper mold 1 and has a plug-in portion 5 facing the lower mold 2. The locking component 4 is provided on the edge of the lower mold 2 and has a movable plug-in groove 6 corresponding to the plug-in portion 5. The plug-in portion 5 and the movable plug-in groove 6 can be locked and limited.

[0020] Understandably, the vehicle radar cover is a protective shell for the vehicle radar system. It needs to have high wave transmittance to avoid interfering with radar signals, as well as good weather resistance, mechanical strength, and sealing performance. This embodiment is a mold for producing the vehicle radar cover. The mold base is the basic part of the mold, supporting and fixing the various components of the mold. It is divided into an upper mold 1 and a lower mold 2. The mating surfaces of the upper mold 1 and the lower mold 2 are respectively provided with a concave mold part and a convex mold part 21. The convex mold part 21 refers to the protruding part in the middle of the surface of the lower mold 2, and the concave mold part refers to the recessed part in the middle of the surface of the upper mold 1. The two are precisely matched to form the shape of the workpiece.

[0021] Two self-locking structures are located on both sides of the mold base, serving to fix the positions of the upper and lower molds 2. The self-locking structure consists of a connector 3 and a locking assembly 4. The connector 3 is located on the edge of the upper mold 1 and has a connector 5 facing the lower mold 2. It can be inserted into a portion of the locking assembly 4 to maintain mold stability. The locking assembly 4 is located on the edge of the lower mold 2 and can cooperate with the connector 5 of the connector 3. It achieves locking and fixing through a movable connector groove 6. The movable connector groove 6 is an adjustable tightness connector groove that can lock and restrict the movement of the connector 5 according to its movement, ensuring mold stability and accuracy.

[0022] Reference Figures 1 to 2 In one embodiment of this application, the locking component 4 includes a first connecting seat 41 and two back-to-back abutting members 42. The abutting members 42 are rotatably connected to the first connecting seat 41. The two abutting members 42 have arc-shaped surfaces 421 on their facing sides, and the two arc-shaped surfaces 421 together form a movable insertion groove 6.

[0023] Understandably, the first connecting seat 41 is the basic part of the locking assembly 4, located at the edge of the lower mold 2, and serves as the connecting platform for the clamping members 42. The two clamping members 42 are connected to the first connecting seat 41 via a rotatable connection, allowing them to rotate around the first connecting seat 41. However, their rotation is restricted, allowing the clamping members 42 to adjust their angle as needed, thereby precisely engaging with the insert 3 of the upper mold 1. The facing sides of the two clamping members 42 have an arc-shaped structure, and the arc-shaped surfaces 421 of the two clamping members 42 together form a movable insertion groove 6, whose shape matches the outer shape of the insertion part 5. The insertion part 3 can be inserted into and engaged in the movable insertion groove 6, thus completing the locking.

[0024] Reference Figures 1 to 2 In one embodiment of this application, the abutting member 42 is provided with a pressure plate 422 on the side opposite to the arc-shaped part 421, and a spring 43 is provided between the pressure plate 422 and the first connecting seat 41.

[0025] Understandably, a pressure plate 422 is provided on the back of the curved surface 421. The function of the pressure plate 422 is to accept external pressure and help maintain close contact between the clamping member 42 and the insert member 3 of the upper mold 1, thereby ensuring that the mold can be firmly fixed. A spring 43 is provided between the pressure plate 422 and the first connecting seat 41. The function of the spring 43 is to provide a certain elastic pressure between the pressure plate 422 and the first connecting seat 41. The spring 43 can be compressed or extended as needed, thereby adjusting the force of the pressure plate 422. When the upper and lower molds 2 are fitted together, the insertion part 5 presses against the curved surface 421, causing the pressure plate 422 to compress the spring 43. The insertion part 5 extends into the movable insertion groove 6. Then, the spring 43 rebounds and presses against the pressure plate 422, driving the curved surface 421 to press against the insertion part 5, thus completing the locking. When it is necessary to separate the upper and lower molds 2, a large pulling force is applied to both, causing the insertion part 5 to press against the curved surface 421 again. The pressure plate 422 compresses the spring 43, and the insertion part 5 moves away from the movable insertion groove 6, thus separating the molds.

[0026] Reference Figures 1 to 2 In one embodiment of this application, the plug-in member 3 includes a second connecting seat 31 and a support plate 32 vertically disposed on the surface of the second connecting seat 31. The end of the support plate 32 has a cylindrical structure to form a plug-in portion 5.

[0027] Understandably, the second connecting seat 31 serves as the base of the connector 3, corresponding to the first connecting seat 41. The support plate 32 is a component connected to the middle surface of the second connecting seat 31, perpendicular to its surface. The support plate 32 structurally provides support and stability for the connector 3, ensuring precise alignment with the movable connector slot 6 in the mold and fulfilling its connecting function. The end of the support plate 32 is designed as a cylindrical structure, facilitating insertion into the movable connector slot 6 to form a secure snap-fit. The cylindrical structure also ensures a more stable and tighter fit between the connector 3 and the locking assembly 4.

[0028] Reference Figures 1 to 2 In one embodiment of this application, the upper mold 1 and the lower mold 2 are respectively provided with grooves 11 and bosses 22 at the corners of the mating surfaces. The bosses 22 are provided with positioning posts 23, and the grooves 11 are provided with positioning holes 12 corresponding to the positioning posts 23.

[0029] Understandably, the upper mold 1 and the lower mold 2 have grooves 11 and bosses 22 at the corners of their contact surfaces. The bosses 22 are the protruding parts of the lower mold 2, while the grooves 11 are the corresponding recessed parts at the corners of the lower mold 2. This design ensures precise alignment of the two molds when closed, thanks to the interlocking of the bosses 22 and grooves 11, thereby enhancing the stability and precision of the molds and preventing unnecessary displacement or loosening during operation. The bosses 22 are equipped with positioning pins 23 for precisely positioning the molds. During mold operation, the positioning pins 23 align with the positioning holes 12 in the upper mold 1, ensuring proper alignment of the upper mold 1 and the lower mold 2.

[0030] This utility model's technical solution employs a self-locking structure at the connection between the upper mold 1 and the lower mold 2. When the upper and lower molds 2 are in contact, the insertion part 5 presses against the arc-shaped part 421, causing the pressure plate 422 to compress the spring 43. The insertion part 5 then extends into the movable insertion groove 6. Immediately afterwards, the spring 43 rebounds and presses against the pressure plate 422, driving the arc-shaped part 421 to press firmly against the insertion part 5, thus completing the locking. When it is necessary to separate the upper and lower molds 2, a larger pulling force is applied to both, causing the insertion part 5 to press against the arc-shaped part 421 again. The pressure plate 422 compresses the spring 43, and the insertion part 5 moves out of the movable insertion groove 6, thus separating the molds. Through the above design, the mold can be conveniently and quickly self-locked and unlocked.
