Description

Technical Field

[0001] This utility model relates to the field of molding technology, specifically a molding die for an automotive sensor housing. Background Technology

[0002] Automotive sensors are input devices for automotive computer systems. They convert various operating conditions of the vehicle, such as vehicle speed, temperature of various media, and engine operating conditions, into electrical signals and transmit them to the computer so that the engine can operate at its best. A molding die, also known as a mold, is a mold made according to the shape and structure of a real object. It is a tool used to shape materials into a certain shape by pressing or casting. An automotive sensor housing molding die is a tool used to manufacture automotive sensor housings.

[0003] An investigation revealed that a Chinese utility model invention patent discloses an automotive sensor housing molding die (publication number: CN219903122 U), comprising a bottom mold plate and a top mold plate that fit together tightly. The bottom mold plate has a cavity inside. A displacement mechanism is provided between the bottom mold plate and the top mold plate. Symmetrical and identical semi-shell molding grooves are formed at the center of the corresponding mating surfaces of the bottom mold plate and the top mold plate. Multiple sets of demolding finger grooves are formed on both sides of the bottom mold plate corresponding to the semi-shell molding grooves. Multiple sets of integrated adapter snap-fit ​​demolding finger groove filling protrusions are formed on both sides of the top mold plate corresponding to the semi-shell molding grooves.

[0004] Although the aforementioned patent uses the setting of demolding finger grooves and filling protrusions, the filling protrusions at the bottom of the top mold plate will move with the top mold plate and thus detach from the demolding finger grooves. Workers can easily remove the molded shell by inserting their fingers into the demolding finger grooves, which facilitates demolding. However, the molded shell needs to be removed manually by the workers. This is not only cumbersome but also poses safety hazards, especially in high temperature or high pressure environments, where manual operation can easily lead to accidents such as crushing injuries. In addition, manual operation is inefficient and cannot meet the needs of large-scale production.

[0005] Therefore, this utility model provides a molding die for an automotive sensor housing to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[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. 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.

[0024] This utility model provides a molding die for an automotive sensor housing, such as... Figure 1-4As shown, the automotive sensor housing molding die includes a base 1, a lower mold 2 fixedly installed on the upper end of the base 1, guide rods 3 fixedly installed at the corners of the lower mold 2, an upper mold 4 movably sleeved on the upper ends of the four sets of guide rods 3, an upper mold cavity 5 provided in the lower end of the upper mold 4, a lower mold cavity 6 provided on the upper side of the lower mold 2, the upper mold cavity 5 and the lower mold cavity 6 are symmetrically arranged vertically, an injection pipe 7 is provided on the upper mold 4, the lower end of the injection pipe 7 is located on the side where the upper mold cavity 5 and the lower mold cavity 6 fit together, and a feeding assembly for ejecting the automotive sensor housing is provided in the base 1.

[0025] After the automotive sensor housing is formed, the upper mold 4 rises, causing the unloading assembly to rise in the upper mold cavity 5 within the lower mold 2, thereby lifting the automotive sensor housing and facilitating rapid unloading of the automotive sensor housing.

[0026] The unloading assembly includes multiple sets of mounting brackets 8, which are fixedly installed on the left and right sides of the base 1. First side plates 9 are slidably installed on the multiple sets of mounting brackets 8 on the left and right sides of the base 1. A lifting plate 10 is fixedly installed between two sets of first side plates 9. Second side plates 11 are slidably installed on the upper end of the multiple sets of mounting brackets 8 on the left and right sides of the base 1. A fixing plate 12 is fixedly installed between two sets of second side plates 11. Multiple sets of connecting rods 13 are fixedly installed on the lower side of the lower mold 2. The multiple sets of connecting rods 13 are fixedly connected to the second side plates 11. A lifting assembly is provided on the upper side of the second side plates 11 and the fixing plate 12.

[0027] After the automotive sensor housing is formed, the upper mold 4 rises on the guide rod 3, and then the lifting plate 10 rises through multiple sets of connecting rods 13. Then the lifting assembly slides out from the lower mold cavity 6 and unfolds, thereby pushing the automotive sensor housing out from the lower mold cavity 6 to complete the unloading operation.

[0028] The lifting assembly includes two sets of columns 14, which are fixedly installed on the lifting plate 10. A top block 15 is fixedly installed on the upper end of the column 14, and a fixed shaft 16 is fixedly installed inside the top block 15. Four sets of fixed blocks 17 are fixedly installed on the upper end of the fixed plate 12. Support rods 18 are rotatably installed on each of the four sets of fixed blocks 17. The upper ends of the four sets of support rods 18 are movably inserted into the two sets of top blocks 15. Connecting shafts 19 are fixedly installed on each of the four sets of support rods 18. Slide grooves 20 are symmetrically opened on both the front and back of the two sets of fixed shafts 16. The four sets of connecting shafts 19 are movably inserted into the four sets of slide grooves 20. Two sets of arc-shaped blocks 21 are rotatably installed on the left and right ends of the two sets of fixed shafts 16. The multiple sets of arc-shaped blocks 21 on the left and right ends of the two sets of fixed shafts 16 are respectively connected to the left and right ends of the four sets of connecting shafts 19.

[0029] The lifting plate 10 drives the column 14 and the top block 15 to rise, thereby causing the connecting shaft 19 at the upper end of the four sets of support rods 18 to slide in the slide groove 20, so that the four sets of arc blocks 21 connected to the left and right ends of the two sets of fixed shafts 16 can rotate and open, thus supporting and pushing out the car sensor housing.

[0030] The multiple sets of arc-shaped blocks 21 are all quarter-cylinder in shape, and the two sets of arc-shaped blocks 21 at the left and right ends of the two sets of fixed shafts 16 fit together to form a semi-cylinder.

[0031] By setting up the quarter-cylindrical arc block 21, the two sets of arc blocks 21 at the left and right ends of the two sets of fixed shafts 16 are fitted together to form a semi-cylindrical shape, which can fit and support the car sensor housing and push it out, avoiding the phenomenon of displacement and skew during the push-out.

[0032] The inner walls of the two sets of sliding grooves 20 at the upper end of the two sets of top blocks 15 are both set in a semi-circular arc shape.

[0033] The inner wall of the semi-circular groove 20 allows for a closer sliding contact with the connecting shaft 19, improving the stability and smoothness of the sliding and thus ensuring the normal operation of the lifting assembly.

[0034] The four sets of support rods 18 on the front and rear sides of the two sets of columns 14 are all set at an angle, and the upper ends of the four sets of support rods 18 are located inside the upper ends of the four sets of fixed shafts 16 on the top block 15.

[0035] The inclined support rod 18 allows the connecting shaft 19 to slide more smoothly in the slide groove 20, which in turn drives the arc block 21 to rotate and open, avoiding jamming or obstruction, and further ensuring the normal operation of the lifting assembly and the smooth ejection of the car sensor housing.

[0036] Working principle: During the molding process of the automotive sensor housing, molten plastic or other molding materials are injected into the cavities of the upper mold cavity 5 and the lower mold cavity 6 through the injection pipe 7. After the material cools and solidifies, the automotive sensor housing is formed. At this time, the mold unloading assembly is activated, and the upper mold 4 rises above the guide rod 3. As the upper mold 4 rises, the lifting plate 10 is driven to rise through multiple sets of connecting rods 13. The lifting plate 10 further drives the column 14 and the top block 15 to rise. As the top block 15 rises, the connecting shaft 19 at the upper end of the four sets of support rods 18 slides in the slide groove 20, so that the connecting shaft 19 can smoothly drive the arc block 21 to rotate and open. The two sets of arc blocks 21 at the left and right ends of the two sets of fixed shafts 16 change from the close state to the semi-cylindrical open state, thereby pushing the automotive sensor housing out of the lower mold cavity 6.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
