Description

Technical Field

[0001] This utility model relates to the field of automotive windshield ventilation cover processing technology, specifically an automotive windshield ventilation cover mold. Background Technology

[0002] The windshield ventilation cover is an important component of the automotive front bulkhead system. Its main functions include sealing, water drainage, ventilation, and decoration. Installed at the front of the bulkhead, it covers the bottom of the windshield and the front of the engine hood. It can prevent rainwater, dust, and other debris from entering the engine compartment, avoiding damage to the engine and electrical systems caused by water accumulation. At the same time, it can guide rainwater on the windshield to flow out of the vehicle, reducing water intrusion into the vehicle, and providing an air intake channel for the air conditioning system to ensure air circulation inside the vehicle.

[0003] In the production of automotive windshield ventilation covers, injection molding is generally used. After the windshield ventilation cover is injection molded, workers will remove it from the injection mold and clean the mold to prevent plastic residue from the previous injection from affecting the next injection. This is usually done manually by using a brush to clean the mold cavities of the upper and lower molds, which is a rather tedious operation. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for a car windshield ventilation cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for a car windshield ventilation cover, comprising a moving injection mold and a fixed injection mold, wherein a horizontal moving frame is slidably mounted on the upper part of the fixed injection mold, an mounting block is slidably mounted on the middle part of the horizontal moving frame, and brushes are symmetrically mounted on the upper and lower positions of the mounting block.

[0006] As a further preferred embodiment of this technical solution, extension frames are symmetrically fixedly installed at both ends of the injection mold, and guide rods are fixedly installed between the two extension frames on the same side. Guide holes are opened at both ends of the horizontal moving frame, and the guide rods are slidably connected to the guide holes. The distance between the two guide rods is greater than the width of the injection mold.

[0007] As a further preferred embodiment of this technical solution, a positioning sleeve is symmetrically fixedly installed in the middle of the mounting block, and a movable rod is symmetrically fixedly installed in the middle of the brush. The movable rod is slidably connected to the positioning sleeve, and a compression spring is sleeved on the outside of the movable rod. One end of the compression spring is fixedly connected to the end of the positioning sleeve, and the other end of the compression spring is fixedly connected to the outside of the brush. A fixing plate is fixedly installed between the two movable rods.

[0008] As a further preferred embodiment of this technical solution, the horizontally movable frame is symmetrically fixedly installed with limiting rods inside, and limiting holes are opened on both sides of the mounting block, with the limiting holes and limiting rods being slidably connected.

[0009] As a further preferred embodiment of this technical solution, positioning rods are fixedly installed at the top of both ends of the mounting block, and the surface of the guide rod is provided with a wave-shaped positioning groove, which is slidably connected to the positioning rod.

[0010] As a further preferred embodiment of this technical solution, a connecting rod is installed between the two fixing plates.

[0011] As a further preferred embodiment of this technical solution, the end of the fixing plate is provided with a movable hole, and the connecting rod is slidably connected to the movable hole.

[0012] This utility model provides a mold for a car windshield ventilation cover plate, which has the following beneficial effects:

[0013] (1) This utility model controls the downward movement of the injection mold and its proximity to the fixed injection mold. Through the operation of the injection components connected to the injection mold and the injection of material, the injection mold and the fixed injection mold realize the injection operation of the windshield ventilation cover of the car. Then, by controlling the upward movement of the injection mold, the two fixed plates are squeezed against each other, causing the two fixed plates to move closer to each other. This causes the movable rod to slide inside the positioning sleeve. At this time, the compression spring is in a compressed state. Then, the connecting rod moves along the trajectory of the guide rod, which causes the two fixed plates to move. This, in turn, moves the horizontal moving frame indirectly connected to the fixed plates along the trajectory of the guide rod, moving the brush. The device moves between the moving mold and the fixed mold, releasing the pressure on the two fixed plates. The compression spring pushes the movable rod, causing it to slide in the opposite direction inside the positioning sleeve. This causes the two brushes to contact and squeeze the injection cavities of the moving mold and the fixed mold respectively. Then, the connecting rod moves along the guide rod's trajectory, causing the two fixed plates to move. This, in turn, moves the horizontal moving frame, which is indirectly connected to the fixed plates, along the guide rod's trajectory. The brushes squeeze and clean the plastic residue inside the injection cavities of the moving mold and the fixed mold, removing the plastic residue from inside the injection cavities of the moving mold and the fixed mold.

[0014] (2) In this utility model, during the process of controlling the moving frame to move along the trajectory of the guide rod, the positioning rods at both ends of the mounting block guide the positioning groove of the wave positioning groove opened on the surface of the hand guide rod, and control the mounting block connected to the positioning rod to move intermittently between the two limit rods inside the horizontal moving frame, thereby driving the brush to move left and right in the injection cavity of the injection moving mold and the injection fixed mold, so as to improve the cleaning effect of the brush on the injection moving mold and the injection fixed mold. Then, the plastic residue inside the injection cavity of the injection moving mold and the injection fixed mold is blown out of the injection moving mold and the injection fixed mold through the air blowing pipe connected to the air pump.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a windshield ventilation cover mold for automobiles includes a moving injection mold 1 and a fixed injection mold 2. A horizontal moving frame 3 is slidably mounted on the upper part of the fixed injection mold 2. An mounting block 4 is slidably mounted on the middle of the horizontal moving frame 3. Brushes 5 are symmetrically mounted on the upper and lower positions of the mounting block 4. Extension frames 6 are symmetrically fixedly mounted on both ends of the fixed injection mold 2. A guide rod 7 is fixedly mounted between the two extension frames 6 on the same side. Guide holes 8 are opened at both ends of the horizontal moving frame 3. The guide rods 7 are slidably connected to the guide holes 8. The distance between the two guide rods 7 is greater than the width of the moving injection mold 1. By controlling the moving injection mold 1 to descend and approach the fixed injection mold 2... The injection molding process, through the operation of the injection components connected to the moving mold 1 and the injection molding of the fixed mold 2, achieves the injection molding operation of the moving mold 1 and the fixed mold 2 for the ventilation cover of the car windshield. Then, by controlling the moving mold 1 to rise, the horizontal moving frame 3 is controlled to move along the trajectory of the guide rod 7, moving the brush 5 between the moving mold 1 and the fixed mold 2. This causes the two brushes 5 to contact and squeeze the injection cavities of the moving mold 1 and the fixed mold 2 respectively. Then, the horizontal moving frame 3 moves along the trajectory of the guide rod 7, and the brushes 5 squeeze and clean the plastic residue inside the injection cavities of the moving mold 1 and the fixed mold 2, thereby cleaning the plastic residue from the injection cavities of the moving mold 1 and the fixed mold 2.

[0022] like Figures 1 to 4 As shown, a positioning sleeve 9 is symmetrically fixedly installed in the middle of the mounting block 4, and a movable rod 10 is symmetrically fixedly installed in the middle of the brush 5. The movable rod 10 is slidably connected to the positioning sleeve 9. A compression spring 11 is sleeved on the outside of the movable rod 10. One end of the compression spring 11 is fixedly connected to the end of the positioning sleeve 9, and the other end of the compression spring 11 is fixedly connected to the outside of the brush 5. A fixing plate 12 is fixedly installed between the two movable rods 10.

[0023] Before cleaning the moving mold 1 and the fixed mold 2, the two fixed plates 12 are pressed together, causing them to move closer together. This causes the movable rod 10 to slide inside the positioning sleeve 9. At this time, the compression spring 11 is in a compressed state. Then, the horizontal moving frame 3 is controlled to move along the trajectory of the guide rod 7, moving the brush 5 between the moving mold 1 and the fixed mold 2. The pressing of the two fixed plates 12 is released. The compression spring 11 pushes the movable rod 10, causing it to slide in the opposite direction inside the positioning sleeve 9. This causes the two brushes 5 to contact and press the injection cavities of the moving mold 1 and the fixed mold 2 respectively, which is used to control the brushes 5 to fully press the injection cavities of the moving mold 1 and the fixed mold 2.

[0024] like Figures 1 to 4 As shown, the horizontal moving frame 3 has symmetrically fixedly installed limit rods 13 inside, and limit holes 14 are opened on both sides of the mounting block 4. The limit holes 14 are slidably connected to the limit rods 13. Positioning rods 15 are fixedly installed on the top of both ends of the mounting block 4. The surface of the guide rod 7 is provided with a wave positioning groove 16, and the wave positioning groove 16 is slidably connected to the positioning rod 15.

[0025] During the process of controlling the horizontal moving frame 3 to move along the trajectory of the guide rod 7, the positioning rods 15 at both ends of the mounting block 4 guide the positioning of the wave positioning groove 16 opened on the surface of the guide rod 7, and control the mounting block 4 connected to the positioning rod 15 to move intermittently between the two limit rods 13 inside the horizontal moving frame 3, thereby driving the brush 5 to move left and right in the injection cavity of the injection moving mold 1 and the injection fixed mold 2, so as to improve the cleaning effect of the brush 5 on the injection moving mold 1 and the injection fixed mold 2.

[0026] like Figures 1 to 4 As shown, a connecting rod 17 is installed between the two fixing plates 12.

[0027] When the horizontal moving frame 3 moves along the trajectory of the guide rod 7, the two fixed plates 12 connected to the connecting rod 17 can be moved by holding the connecting rod 17, thereby facilitating the control of the horizontal moving frame 3, which is indirectly connected to the fixed plates 12, to move along the trajectory of the guide rod 7.

[0028] like Figures 1 to 4As shown, the fixed plate 12 has a movable hole 18 at its end, and the connecting rod 17 is slidably connected to the movable hole 18.

[0029] When the two fixed plates 12 are pressed together and brought closer to each other, the connecting rod 17 can slide inside the movable hole 18 of the fixed plate 12, so as to realize the continuous connection between the connecting rod 17 and the two fixed plates 12.

[0030] This utility model provides a mold for a car windshield ventilation cover plate, the specific working principle of which is as follows:

[0031] In use, the device controls the moving mold 1 to descend and approach the fixed mold 2. Through the operation of the injection components connected to the moving mold 1 and the injection of material, the moving mold 1 and the fixed mold 2 perform the injection molding operation on the car windshield ventilation cover, removing the windshield ventilation cover. Then, by controlling the moving mold 1 to rise, it presses against the two fixed plates 12, causing them to move closer together. This moves the movable rod 10 to slide inside the positioning sleeve 9. At this time, the compression spring 11 is in a compressed state and then moves along the trajectory of the guide rod 7. Rod 17 will move the two fixed plates 12, thereby moving the horizontal moving frame 3, which is indirectly connected to the fixed plates 12, along the trajectory of guide rod 7. This moves the brush 5 between the moving injection mold 1 and the fixed injection mold 2, releasing the pressure on the two fixed plates 12. The compression spring 11 pushes the movable rod 10, causing it to slide in the opposite direction inside the positioning sleeve 9. This causes the two brushes 5 to contact and press the injection cavities of the moving injection mold 1 and the fixed injection mold 2 respectively. Then, the connecting rod 17 moves along the trajectory of guide rod 7, moving the two fixed plates 12. The plate 12 moves, thereby moving the horizontally moving frame 3, which is indirectly connected to the fixed plate 12, along the trajectory of the guide rod 7. The brush 5 squeezes and cleans the plastic residue inside the injection cavities of the moving mold 1 and the fixed mold 2, removing the plastic residue from the injection cavities of the moving mold 1 and the fixed mold 2. As the horizontally moving frame 3 moves along the trajectory of the guide rod 7, the positioning rods 15 at both ends of the mounting block 4 guide the positioning of the wave positioning grooves 16 on the surface of the guide rod 7, thus controlling the mounting block 4 connected to the positioning rods 15. The two limiting rods 13 inside the horizontal moving frame 3 move intermittently, which in turn drives the brush 5 to move left and right in the injection cavity of the moving mold 1 and the fixed mold 2, in order to improve the cleaning effect of the brush 5 on the moving mold 1 and the fixed mold 2. Then, the plastic residue inside the injection cavity of the moving mold 1 and the fixed mold 2 is blown out through the air blowing pipe connected to the air pump. After cleaning, the horizontal moving frame 3 is moved out of the area of ​​the moving mold 1 and the fixed mold 2 along the trajectory of the guide rod 7, and then the next cleaning can be carried out.
