Description

Technical Field

[0001] This invention belongs to the field of crankshaft position sensor manufacturing technology, and specifically relates to waterproof automotive crankshaft position sensor manufacturing equipment and process. Background Technology

[0002] The crankshaft position sensor plays a crucial role in the automotive engine management system. It provides the engine control module (ECM) with information on the crankshaft's rotational speed and specific position. The ECM then uses this information for controlling the phase adjuster, ignition timing, fuel injection timing, and misfire detection. It also has directional detection capabilities. However, when a car is wet or driving through water, the crankshaft position sensor is prone to short-circuiting due to water ingress, which can cause the engine to fail to ignite and thus affect the car's normal operation.

[0003] Existing manufacturing equipment for waterproof automotive crankshaft position sensors has the following drawbacks when using molds for shaping the crankshaft position sensor housing:

[0004] 1. The housing of the crankshaft position sensor is made of plastic. Because plastic has the property of thermal expansion and contraction, it may become stuck in the groove on the edge of the mold during demolding. This makes it difficult to manually remove the mold, and improper handling may also damage the product, thus affecting the product quality.

[0005] 2. After the housing of the crankshaft position sensor is cast, it still needs to be manually picked up and fed, which increases the labor intensity of the workers and affects the processing efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing waterproof automotive crankshaft position sensor manufacturing equipment and processes, the advantages of which are:

[0007] 1. After the crankshaft position sensor housing is cast and molded, there is no need for manual removal of the mold during the demolding process. Instead, an automatic ejection method is used to avoid damage to the product caused by improper handling, thereby improving product quality.

[0008] 2. After the housing of the crankshaft position sensor is cast, there is no need for manual handling and feeding, thereby reducing the labor intensity of workers and further improving the processing efficiency.

[0009] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a waterproof automotive crankshaft position sensor production equipment, including a processing table, a conveyor frame bolted to the rear side of the processing table, a lower mold placement box bolted to the top of the processing table, a lower mold recess frame provided on the inner side of the top of the lower mold placement box, a mold lifting assembly provided in the middle of the bottom side inside the lower mold placement box, the top of the mold lifting assembly located on the bottom side inside the lower mold recess frame, an upper mold assembly provided on the top of the processing table, the upper mold assembly located on the top of the lower mold recess frame, support and buffer assemblies bolted to both sides of the bottom side inside the lower mold placement box, the support and buffer assemblies located at the bottom of the mold lifting assembly, a pushing assembly provided on the outer side of the top of the lower mold placement box, an auxiliary sliding assembly provided at the bottom of the pushing assembly, a sliding assembly bolted to the rear side of the top of the lower mold placement box, the rear side of the sliding assembly located on the top side inside the conveyor frame, a conveying assembly provided inside the conveyor frame, and a blowing assembly provided on the right side of the top of the conveyor frame.

[0010] The above technical solution involves setting up a processing table, a lower mold placement box, a lower mold recess, a mold lifting assembly, an upper mold assembly, and a support assembly. After injecting raw material into the lower mold recess, the mold lifting assembly inside the lower mold placement box blocks the bottom of the recess. Then, the upper mold assembly descends and fits against the lower mold recess. During this process, the support assembly located at the bottom of the lower mold placement box supports and reinforces the mold lifting assembly. After the crankshaft position sensor housing cools and solidifies, the upper mold assembly returns to its initial position. Then, the mold lifting assembly is simultaneously activated and moves upward inside the lower mold recess, automatically pushing the formed crankshaft position sensor housing into the lower mold recess. This ensures that the top of the mold lifting assembly is flush with the top side of the lower mold recess, eliminating the need for manual handling during demolding after the crankshaft position sensor housing is cast, thus avoiding damage to the product from improper handling. To improve product quality and prevent damage, a conveyor system, pusher assembly, auxiliary sliding assembly, sliding assembly, conveying assembly, and air blowing assembly are used. After the crankshaft position sensor housing is cast by the lifting mold assembly, it is pushed out of the lower mold recess. The pusher assembly on the front top of the lower mold placement box moves the crankshaft position sensor housing backward. Then, the auxiliary sliding assembly on the rear top of the lower mold placement box slides it into the conveyor system. The conveying assembly inside the conveyor system then slides the crankshaft position sensor housing onto the surface of the conveying assembly for transport. Finally, the air blowing assembly on the right side of the top of the conveyor system cools the crankshaft position sensor housing on the surface of the conveying assembly. This system eliminates the need for manual handling and feeding of the crankshaft position sensor housing after casting, reducing labor costs and improving processing efficiency.

[0011] The present invention is further configured such that: the lifting mold assembly includes a first hydraulic cylinder and a lower template, the first hydraulic cylinder is bolted to the middle of the bottom side inside the lower mold placement box, the lower template is bolted to the telescopic end of the first hydraulic cylinder, and the lower template is snapped into the bottom side inside the lower mold recess and slidably connected.

[0012] By adopting the above technical solution, by setting a first hydraulic cylinder and a lower template, injection molding material is injected into the lower mold recess. Then, the lower template at the top of the first hydraulic cylinder inside the lower mold placement box blocks the bottom of the lower mold recess, thereby facilitating subsequent use.

[0013] The present invention is further configured such that: the upper mold assembly includes a bracket, a second hydraulic cylinder and an upper mold, the bracket is bolted to the top of the processing table, the second hydraulic cylinder is bolted to the top of the bracket, the telescopic end of the second hydraulic cylinder passes through the top of the bracket, and the upper mold is bolted to the bottom of the second hydraulic cylinder.

[0014] By adopting the above technical solution, a bracket, a second hydraulic cylinder, and an upper mold are set up. The second hydraulic cylinder at the top of the bracket pushes the upper mold downward, so that the upper mold fits into the lower mold cavity frame, thereby realizing the injection molding of the crankshaft position sensor housing. After the crankshaft position sensor housing cools and solidifies, the upper mold returns to its initial position under the action of the second hydraulic cylinder. Then, the first hydraulic cylinder is activated to push the lower mold plate upward inside the lower mold cavity frame, so that the formed crankshaft position sensor housing is automatically pushed into the interior of the lower mold cavity frame, and the top of the lower mold plate is flush with the top side inside the lower mold cavity frame. This eliminates the need for manual handling during the demolding process after the crankshaft position sensor housing is cast, thus avoiding damage to the product caused by improper handling and improving product quality.

[0015] The present invention is further configured such that: the support assembly includes a spring telescopic column and a connecting plate, the spring telescopic column is respectively bolted to both sides of the bottom side inside the lower mold placement box, the connecting plate is bolted to the top of the spring telescopic column, and the top of the connecting plate is in contact with the bottom of the lower mold.

[0016] By adopting the above technical solution, spring telescopic columns and connecting plates are set up, and the spring telescopic columns located on the bottom side inside the lower mold placement box, together with the connecting plates, support and reinforce the lower mold.

[0017] The present invention is further configured such that: the pushing assembly includes an electric telescopic rod and a push plate, the electric telescopic rod is bolted to the front side of the top left side of the lower mold placement box, the push plate is slidably connected to the outside of the top of the lower mold placement box, and the left side of the front side of the push plate is bolted to the telescopic end of the electric telescopic rod.

[0018] Using the above technical solution, by setting an electric telescopic rod and a push plate, after the crankshaft position sensor housing is cast and ejected from the interior of the lower mold recess, the electric telescopic rod on the top left side of the lower mold placement box is activated to push the push plate, thereby causing the push plate to move the crankshaft position sensor housing to the rear.

[0019] The present invention is further configured such that: the auxiliary sliding component includes a sliding groove and a slider, the sliding groove is respectively opened on both sides of the top of the lower mold placement box, the slider is respectively bolted to both sides of the bottom of the push plate, and the slider is slidably connected inside the sliding groove.

[0020] By adopting the above technical solution, by setting a slide groove and a slider, when the push plate moves, the slider set at the bottom of the push plate can simultaneously slide inside the slide groove at the top of the lower mold placement box.

[0021] The invention is further configured such that: the sliding assembly includes a slanted slide plate and side plates, the slanted slide plate is bolted to the rear side of the top of the lower mold placement box, the bottom of the slanted slide plate is located inside the top of the conveyor frame, and the side plates are respectively bolted to both sides of the top of the slanted slide plate.

[0022] Using the above technical solution, by setting up a slanted slide plate and a side plate, when the push plate pushes the crankshaft position sensor housing to move to the rear, the slanted slide plate set on the top rear side of the lower mold placement box, together with the side plate, slides the crankshaft position sensor housing into the inside of the conveyor frame.

[0023] The present invention is further configured such that: the conveying assembly includes a motor, a main shaft, a secondary shaft, and a conveyor belt; the motor is bolted to the front side of the rear side of the conveying frame; the output end of the motor passes through the rear side of the conveying frame; the rear side of the main shaft is bolted to the output end of the motor; the front side of the main shaft is rotatably connected to the front side inside the conveying frame; the secondary shaft is rotatably connected to the right side inside the conveying frame; and the conveyor belt is sleeved on the outside of the main shaft and the secondary shaft.

[0024] By adopting the above technical solution, a motor, main shaft, secondary shaft, and conveyor belt are set up. The motor on the left side of the starting conveyor frame drives the main shaft to rotate with the cooperation of the secondary shaft, so that the crankshaft position sensor housing slides onto the surface of the conveyor belt for automatic conveying. In this way, after the crankshaft position sensor housing is cast, there is no need for manual handling and feeding, thereby reducing the labor intensity of workers and further improving the processing efficiency.

[0025] The present invention is further configured such that: the blowing assembly includes a blowing frame, a fan and a guide pipe, the blowing frame is bolted to the right side of the top of the conveyor frame, the fan is bolted to the top of the blowing frame, the front side of the guide pipe is bolted to and connected to the output end of the fan, and the bottom of the guide pipe is connected to the top of the blowing frame.

[0026] By adopting the above technical solution, by setting up a blower frame, a fan and an air guide pipe, the fan located at the top of the blower frame blows air, and then the air guide pipe conveys the air into the interior of the blower frame, thereby achieving the purpose of cooling the crankshaft position sensor housing conveyed on the surface of the conveyor belt inside the conveyor frame.

[0027] The manufacturing process for waterproof automotive crankshaft position sensors includes the following steps:

[0028] S1. Automatic ejection of the crankshaft position sensor housing: After injecting injection molding material into the lower mold cavity, the bottom of the lower mold cavity is blocked by the lifting mold assembly inside the lower mold placement box. Then, the upper mold assembly is activated to descend and fit against the lower mold cavity. During this process, the support and buffer assembly located on the bottom side inside the lower mold placement box supports and reinforces the lifting mold assembly. After the crankshaft position sensor housing cools and forms, the upper mold assembly returns to its initial position. Then, the lifting mold assembly is activated again to move upward inside the lower mold cavity, thereby automatically pushing the formed crankshaft position sensor housing into the lower mold cavity. The top of the lifting mold assembly is flush with the top side inside the lower mold cavity. This eliminates the need for manual handling during the demolding process after the crankshaft position sensor housing is cast, thus avoiding damage to the product due to improper handling and improving product quality.

[0029] S2. Automatic conveying of the crankshaft position sensor housing: After the lifting mold assembly casts and forms the crankshaft position sensor housing, it is pushed out of the lower mold recess by the push assembly on the front of the top of the lower mold placement box. The housing is then moved backward by the push assembly on the rear of the lower mold placement box. It is then slid into the conveyor frame by the auxiliary sliding assembly on the rear of the lower mold placement box. The conveyor assembly inside the conveyor frame is then activated, causing the crankshaft position sensor housing to slide onto the surface of the conveyor assembly for transport. Finally, the air blowing assembly on the right side of the top of the conveyor frame cools the crankshaft position sensor housing on the surface of the conveyor assembly. This process eliminates the need for manual handling and feeding of the crankshaft position sensor housing after casting, reducing labor intensity and improving processing efficiency.

[0030] In summary, the present invention has the following beneficial effects:

[0031] 1. By setting up a processing table, a lower mold placement box, a lower mold recess, a mold lifting assembly, an upper mold assembly, and a support assembly, the injection molding material is injected into the lower mold recess. Then, the mold lifting assembly inside the lower mold placement box blocks the bottom of the lower mold recess. Next, the upper mold assembly is activated to descend and fit against the lower mold recess. During this process, the support assembly located on the bottom side inside the lower mold placement box supports and reinforces the mold lifting assembly. After the crankshaft position sensor housing cools and forms, the upper mold assembly returns to its initial position. Then, the mold lifting assembly is activated again to move upward inside the lower mold recess, automatically pushing the formed crankshaft position sensor housing into the lower mold recess. This ensures that the top of the mold lifting assembly is flush with the top side inside the lower mold recess. This eliminates the need for manual handling during the demolding process after the crankshaft position sensor housing is cast, thus avoiding damage to the product due to improper handling and improving product quality.

[0032] 2. By setting up a conveyor frame, a pushing component, an auxiliary sliding component, a sliding component, a conveying component, and a blowing component, after the lifting mold component casts the crankshaft position sensor housing out of the lower mold recess, the pushing component on the front top of the lower mold placement box is activated to push the crankshaft position sensor housing to the rear. Then, the auxiliary sliding component on the rear top of the lower mold placement box slides it into the conveyor frame. Then, the conveying component inside the conveyor frame is activated, causing the crankshaft position sensor housing to slide onto the surface of the conveying component for transport. Finally, the blowing component on the right side of the top of the conveyor frame blows air onto the surface of the conveying component to cool it down. The whole process eliminates the need for manual handling and feeding after the crankshaft position sensor housing is cast, thereby reducing labor fatigue and further improving processing efficiency.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Example 1:

[0047] refer to Figure 1-5A waterproof automotive crankshaft position sensor production equipment includes a processing table 1. A lower mold placement box 3 is bolted to the top of the processing table 1. A lower mold recess 4 is provided on the inner side of the top of the lower mold placement box 3. A lifting mold assembly 5 is provided in the middle of the bottom side inside the lower mold placement box 3. The top of the lifting mold assembly 5 is located on the bottom side inside the lower mold recess 4. An upper mold assembly 6 is provided on the top of the processing table 1. The upper mold assembly 6 is located on the top of the lower mold recess 4. Supporting components 7 are bolted to both sides of the bottom side inside the lower mold placement box 3. The supporting components 7 are located at the bottom of the lifting mold assembly 5. By setting up the processing table 1, lower mold placement box 3, lower mold recess 4, lifting mold assembly 5, upper mold assembly 6 and supporting components 7, injection molding material is injected into the lower mold recess 4, and then the lower mold recess is adjusted by the lifting mold assembly 5 inside the lower mold placement box 3. The bottom of frame 4 is blocked, and then the upper mold assembly 6 is activated to descend and fit into the lower mold recess 4. During this process, the support assembly 7 located on the bottom side inside the lower mold placement box 3 supports and reinforces the lifting mold assembly 5. After the crankshaft position sensor housing cools and forms, the upper mold assembly 6 returns to its initial position. Then, the lifting mold assembly 5 is activated to move upward inside the lower mold recess 4, so that the formed crankshaft position sensor housing is automatically pushed into the lower mold recess 4, and the top of the lifting mold assembly 5 is flush with the top side inside the lower mold recess 4. This allows the crankshaft position sensor housing to be demolded without manual handling, thus avoiding damage to the product caused by improper handling and improving product quality.

[0048] like Figure 3 As shown, the lifting mold assembly 5 includes a first hydraulic cylinder 501 and a lower mold plate 502. The first hydraulic cylinder 501 is bolted to the middle of the bottom side inside the lower mold placement box 3, and the lower mold plate 502 is bolted to the telescopic end of the first hydraulic cylinder 501. The lower mold plate 502 is snapped into the bottom side inside the lower mold recess 4 and slidably connected. By setting the first hydraulic cylinder 501 and the lower mold plate 502, injection molding material is injected into the lower mold recess 4. Then, the lower mold plate 502 at the top of the first hydraulic cylinder 501 inside the lower mold placement box 3 blocks the bottom of the lower mold recess 4, thereby facilitating subsequent use.

[0049] like Figure 4As shown, the upper mold assembly 6 includes a bracket 601, a second hydraulic cylinder 602, and an upper mold 603. The bracket 601 is bolted to the top of the processing table 1, the second hydraulic cylinder 602 is bolted to the top of the bracket 601, and the telescopic end of the second hydraulic cylinder 602 passes through the top of the bracket 601. The upper mold 603 is bolted to the bottom of the second hydraulic cylinder 602. By setting up the bracket 601, the second hydraulic cylinder 602, and the upper mold 603, the second hydraulic cylinder 602 at the top of the bracket 601 is activated to push the upper mold 603 downward, thereby causing the upper mold 603 to fit against the lower mold recess 4, thus realizing the machining of the crankshaft position sensor housing. Injection molding is performed, and after the crankshaft position sensor housing cools and solidifies, the upper mold 603 returns to its initial position under the drive of the second hydraulic cylinder 602. Then, the first hydraulic cylinder 501 is activated to push the lower mold plate 502 upward inside the lower mold recess 4, thereby automatically pushing the formed crankshaft position sensor housing into the lower mold recess 4, and making the top of the lower mold plate 502 flush with the top side inside the lower mold recess 4. This eliminates the need for manual handling during the demolding process after the crankshaft position sensor housing is cast, thus avoiding damage to the product due to improper handling and improving product quality.

[0050] like Figure 5 As shown, the support assembly 7 includes a spring telescopic column 701 and a connecting plate 702. The spring telescopic column 701 is bolted to both sides of the bottom inside the lower mold placement box 3, and the connecting plate 702 is bolted to the top of the spring telescopic column 701. The top of the connecting plate 702 contacts the bottom of the lower mold template 502. By setting the spring telescopic column 701 and the connecting plate 702, the lower mold template 502 is supported and reinforced by the spring telescopic column 701 located on the bottom inside the lower mold placement box 3 in conjunction with the connecting plate 702.

[0051] Brief description of the usage process: First, injection molding material is injected into the lower mold recess 4. Then, the lower template 502 at the top of the first hydraulic cylinder 501 inside the lower mold placement box 3 blocks the bottom of the lower mold recess 4. Then, the upper mold 603 is pushed downward by the second hydraulic cylinder 602 at the top of the starting bracket 601, so that the upper mold 603 fits with the lower mold recess 4, thereby realizing the injection molding of the crankshaft position sensor housing. During this process, the spring telescopic column 701 located on the bottom side inside the lower mold placement box 3, together with the connecting plate 702, supports and reinforces the lower template 502. After the crankshaft position sensor housing is cooled and formed, its upper mold 603 returns to its initial position under the drive of the second hydraulic cylinder 602. Then, the first hydraulic cylinder 501 pushes the lower mold plate 502 upward inside the lower mold cavity 4, thereby automatically pushing the formed crankshaft position sensor housing into the lower mold cavity 4, and making the top of the lower mold plate 502 flush with the top side inside the lower mold cavity 4. This eliminates the need for manual handling during the demolding process after the crankshaft position sensor housing is cast, thus avoiding damage to the product due to improper handling and improving product quality.

[0052] Example 2:

[0053] refer to Figure 6-10 A waterproof automotive crankshaft position sensor production equipment includes a conveyor frame 2. The conveyor frame 2 is bolted to the rear side of the processing table 1. A pushing component 8 is installed on the outer side of the top of the lower mold placement box 3. An auxiliary sliding component 9 is installed at the bottom of the pushing component 8. A sliding component 10 is bolted to the rear side of the top of the lower mold placement box 3. The rear side of the sliding component 10 is located on the top side inside the conveyor frame 2. A conveying component 11 is installed inside the conveyor frame 2. A blowing component 12 is installed on the right side of the top of the conveyor frame 2. By configuring the conveyor frame 2, pushing component 8, auxiliary sliding component 9, sliding component 10, conveying component 11, and blowing component 12, after the lifting mold component 5 casts the crankshaft position sensor housing out of the lower mold recess 4, the lower mold is then activated. The pushing component 8 on the top front side of the mold placement box 3 pushes the crankshaft position sensor housing to move to the rear side. Then, it slides into the inside of the conveyor frame 2 through the auxiliary sliding component 9 set on the top rear side of the lower mold placement box 3. Then, the conveying component 11 inside the conveyor frame 2 is activated, so that the crankshaft position sensor housing slides onto the surface of the conveying component 11 for conveying. Finally, the blowing component 12 set on the top right side of the conveyor frame 2 blows air onto the surface of the conveying component 11 to cool it down. In this way, after the crankshaft position sensor housing is cast, there is no need for manual handling and feeding, thereby reducing the labor fatigue of workers and further improving the processing efficiency.

[0054] like Figure 6As shown, the pushing assembly 8 includes an electric telescopic rod 801 and a push plate 802. The electric telescopic rod 801 is bolted to the front side of the top left side of the lower mold placement box 3. The push plate 802 is slidably connected to the outer side of the top of the lower mold placement box 3. The left side of the front side of the push plate 802 is bolted to the telescopic end of the electric telescopic rod 801. By setting the electric telescopic rod 801 and the push plate 802, after the crankshaft position sensor housing is ejected from the interior of the lower mold recess 4 after casting, the electric telescopic rod 801 on the top left side of the lower mold placement box 3 is activated to push the push plate 802, thereby causing the push plate 802 to push the crankshaft position sensor housing to move backward.

[0055] like Figure 7 As shown, the auxiliary sliding component 9 includes a slide groove 901 and a slider 902. The slide groove 901 is respectively opened on both sides of the top of the lower mold placement box 3, and the slider 902 is respectively bolted to both sides of the bottom of the push plate 802. The slider 902 is slidably connected inside the slide groove 901. By setting the slide groove 901 and the slider 902, when the push plate 802 moves, the slider 902 set at the bottom of the push plate 802 simultaneously slides inside the slide groove 901 at the top of the lower mold placement box 3.

[0056] like Figure 8 As shown, the sliding assembly 10 includes a slanted slide plate 1001 and a side plate 1002. The slanted slide plate 1001 is bolted to the rear side of the top of the lower mold placement box 3. The bottom of the slanted slide plate 1001 is located inside the top of the conveyor frame 2. The side plates 1002 are respectively bolted to both sides of the top of the slanted slide plate 1001. By setting the slanted slide plate 1001 and the side plate 1002, when the push plate 802 pushes the crankshaft position sensor housing to move to the rear, the crankshaft position sensor housing is slid into the interior of the conveyor frame 2 by the slanted slide plate 1001 set on the rear side of the top of the lower mold placement box 3 in conjunction with the side plate 1002.

[0057] like Figure 9As shown, the conveying assembly 11 includes a motor 1101, a main shaft 1102, a secondary shaft 1103, and a conveyor belt 1104. The motor 1101 is bolted to the front side of the rear side of the conveyor frame 2, and the output end of the motor 1101 passes through the rear side of the conveyor frame 2. The rear side of the main shaft 1102 is bolted to the output end of the motor 1101, and the front side of the main shaft 1102 is rotatably connected to the front side inside the conveyor frame 2. The secondary shaft 1103 is rotatably connected to the right side inside the conveyor frame 2. The conveyor belt 1104 is sleeved on the outside of the main shaft 1102 and the secondary shaft 1103, and the conveyor belt 1104 is connected to the conveyor frame 2. The system consists of a motor 1101, a main shaft 1102, a secondary shaft 1103, and a conveyor belt 1104. The motor 1101 on the left side of the starting conveyor frame 2 drives the main shaft 1102, which, in conjunction with the secondary shaft 1103, drives the conveyor belt 1104 to rotate. This causes the crankshaft position sensor housing to slide onto the surface of the conveyor belt 1104 and be automatically conveyed. As a result, once the crankshaft position sensor housing has been cast, there is no need for manual handling and feeding, thereby reducing labor costs and further improving processing efficiency.

[0058] like Figure 10 As shown, the air blowing assembly 12 includes an air blowing frame 1201, a fan 1202, and an air guide pipe 1203. The air blowing frame 1201 is bolted to the right side of the top of the conveyor frame 2. The fan 1202 is bolted to the top of the air blowing frame 1201. The front side of the air guide pipe 1203 is bolted to and connected to the output end of the fan 1202. The bottom of the air guide pipe 1203 is connected to the top of the air blowing frame 1201. By setting up the air blowing frame 1201, the fan 1202 and the air guide pipe 1203, the fan 1202 located at the top of the air blowing frame 1201 blows air, and then the air guide pipe 1203 conveys the air into the interior of the air blowing frame 1201. This achieves the purpose of cooling the crankshaft position sensor housing conveyed on the surface of the conveyor belt 1104 inside the conveyor frame 2.

[0059] Brief description of the usage process: First, after the crankshaft position sensor housing is cast and ejected from the lower mold recess 4, the electric telescopic rod 801 on the top left side of the lower mold placement box 3 is activated to push the push plate 802. This causes the push plate 802 to move the crankshaft position sensor housing backward. At the same time, as the push plate 802 moves, the slider 902 at the bottom of the push plate 802 slides within the groove 901 at the top of the lower mold placement box 3. Then, as the push plate 802 moves the crankshaft position sensor housing backward, the inclined slide plate 1001 on the top rear side of the lower mold placement box 3, in conjunction with the side plate 1002, slides the crankshaft position sensor housing into the conveyor frame 2. Then, the motor 1101 on the left side of the starting conveyor frame 2 drives the main shaft 1102 to rotate the conveyor belt 1104 with the cooperation of the secondary shaft 1103. This causes the crankshaft position sensor housing to slide onto the surface of the conveyor belt 1104 for automatic conveying. Then, the fan 1202 located at the top of the air blowing frame 1201 blows air, and then the air guide pipe 1203 conveys the air into the air blowing frame 1201. This achieves the purpose of cooling the crankshaft position sensor housing conveyed on the surface of the conveyor belt 1104 inside the conveyor frame 2. As a whole, after the crankshaft position sensor housing is cast, there is no need for manual handling and feeding, thereby reducing the labor intensity of workers and further improving the processing efficiency.

2. A manufacturing process for a waterproof automotive crankshaft position sensor, characterized by: Includes the following steps: S1. Automatic ejection of the crankshaft position sensor housing: After injecting injection molding material into the lower mold recess (4), the bottom of the lower mold recess (4) is blocked by the lifting mold assembly (5) inside the lower mold placement box (3). Then, the upper mold assembly (6) is activated to descend and fit with the lower mold recess (4). During this process, the support assembly (7) located on the bottom side inside the lower mold placement box (3) supports and reinforces the lifting mold assembly (5). After the crankshaft position sensor housing is cooled and formed, the upper mold assembly (6) returns to the initial position. Then, the lifting mold assembly (5) is activated synchronously to move upward inside the lower mold recess (4), so that the formed crankshaft position sensor housing is automatically pushed into the lower mold recess (4), and the top of the lifting mold assembly (5) is flush with the top side inside the lower mold recess (4). This achieves that the crankshaft position sensor housing does not need to be manually picked up during the demolding process after casting, thereby avoiding damage to the product due to improper handling and improving the quality of the product. S2. Automatic conveying of the crankshaft position sensor housing: After the lifting mold assembly (5) casts and forms the crankshaft position sensor housing, it is pushed out of the lower mold recess (4) and then pushed to the rear by the pushing assembly (8) on the front side of the top of the lower mold placement box (3). Then, it is slid into the conveyor frame (2) by the auxiliary sliding assembly (9) set on the rear side of the top of the lower mold placement box (3). Then, it is slid into the conveyor frame (2) by the conveying assembly (11) inside the conveyor frame (2). Finally, it is slid into the surface of the conveyor assembly (11) by the blowing assembly (12) set on the right side of the top of the conveyor frame (2). Finally, it is cooled by blowing air onto the surface of the conveyor assembly (11). In this way, the crankshaft position sensor housing does not need to be manually picked up and fed after it is cast and formed, thereby reducing the labor intensity of the workers and further improving the processing efficiency.
