Description

Technical Field

[0001] This utility model belongs to the field of loading mold technology, specifically a top-and-bottom flip loading mold with a film covering mechanism. Background Technology

[0002] When foaming automotive interior parts, the loading mold directly fills the mold with foaming resin, which is heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed. The bubble nuclei grow to produce foam plastic parts.

[0003] However, existing loading molds require installation and disassembly before and after production, as well as product feeding and unloading. The high mold temperature before and after molding causes significant operational inconvenience. Furthermore, existing technology requires unloading the product and then using a separate coating mechanism for lamination, which severely impacts coating efficiency. Additionally, during re-coating, product accumulation leads to cooling, necessitating reheating before re-coating, significantly increasing production costs and product molding time. Therefore, there is an urgent need to design a top-and-bottom flipping loading mold with a coating mechanism to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a top-and-bottom flip-type loading mold with a coating mechanism, which solves the problems of difficult loading and unloading and demolding of existing loading molds, as well as the problem that the coating mechanism requires another process to coat the product, which seriously increases production costs and product forming time.

[0005] To solve the above-mentioned technical problems, this utility model provides a top-and-bottom flipping loading mold with a film-coating mechanism, including a frame, an upper mold frame, an upper mold flipping cylinder, a lower mold frame, and a film-coating mechanism. Gear lifting mechanisms are provided on both vertical frames of the frame. The two ends of the upper mold frame are respectively connected to two of the gear lifting mechanisms via connecting shafts. A fixing plate is provided between the two gear lifting mechanisms, located on the side away from the connecting shafts and above the upper mold frame. The upper mold flipping cylinder is mounted on the fixing plate, and its output end is connected to the upper part of the upper mold frame. An upper mold is installed at the bottom of the upper mold frame.

[0006] One side of the lower mold frame is connected to the machine frame via several first rotating shafts. Several lower mold tilting cylinders are obliquely installed inside the machine frame to drive the lower mold frame to tilt. Two connecting plates are respectively provided at both ends of the bottom of the film coating mechanism. The two connecting plates are connected to the film coating mechanism via several telescopic guide column assemblies and several cylinder assemblies. The two connecting plates are installed on the top of the lower mold frame. The lower mold is installed on the lower mold frame. Under the drive of the several telescopic guide column assemblies, the film coating mechanism applies the film to the product inside the lower mold.

[0007] Furthermore, there are at least four telescopic guide post assemblies, which are symmetrically arranged on the two connecting plates. Each telescopic guide post assembly includes a first fixing seat and a telescopic guide post. The first fixing seat is fixedly arranged on the connecting plate, and the telescopic guide post is fixedly arranged at the bottom of the film coating mechanism, with its telescopic end extending into the first fixing seat and fixed by fasteners.

[0008] Furthermore, the coating mechanism includes a set of linear guides, four synchronous pulleys, two synchronous belts, a film roll, and a motor. The set of linear guides is symmetrically arranged on the top of the telescopic guide column. The four synchronous pulleys are arranged in pairs, and each pair of synchronous pulleys is respectively arranged on the inner side of both ends of each linear guide. Each synchronous belt is respectively sleeved on each pair of synchronous pulleys. The film roll is arranged on one side of one set of linear guides and on one side of the synchronous belt. The outer side wall of the synchronous belt has a number of needles evenly distributed to drag the film. The motor is mounted on the linear guides, and its output shaft is connected to the shaft of one of the pairs of synchronous pulleys.

[0009] Furthermore, a cutting mechanism is provided on a set of linear guides, and the cutting end of the cutting mechanism is located above the synchronous belt.

[0010] Furthermore, a mounting base is provided on one side of a set of linear guide rails, and the membrane roll is installed in the mounting base through a second rotating shaft. One end of the second rotating shaft passes through a side wall of the mounting base and is connected to a wrench. The membrane roll is arranged perpendicularly to the linear guide rails.

[0011] Furthermore, each cylinder assembly includes a second fixed seat and a cylinder. The second fixed seat is fixedly disposed at the bottom of the linear guide rail, and the cylinder is fixedly disposed on the connecting plate, with its output end passing through the second fixed seat and locked by fasteners.

[0012] Furthermore, each of the gear lifting mechanisms includes a main cylinder, a side plate, and a rack. The main cylinder is disposed within the vertical frame of the machine frame, and its output end is connected to the side plate via a connecting seat. One side of the side plate is connected to one end of the fixed plate. The racks are respectively vertically disposed on both sides of the vertical frame of the machine frame.

[0013] Furthermore, two third rotating shafts are respectively inserted between the two ends of the side plates of the two gear lifting mechanisms. The two ends of the two third rotating shafts extend out of the side plates on both sides and are fitted with gears. The gears are configured to cooperate with the corresponding racks.

[0014] Furthermore, each of the side plates has a plurality of bearing seats spaced apart on its outer wall for the passage of the third rotating shaft.

[0015] The beneficial effects of this utility model are as follows: The loading mold in this utility model can achieve both flipping and vertical movement of the upper mold frame through the upper mold flipping cylinder and gear lifting mechanism, effectively improving the multi-functionality of the upper mold frame; the film coating mechanism can be driven to move up and down through the cylinder assembly, and the telescopic guide column of the telescopic guide column assembly can extend and retract simultaneously to improve the operational stability of the film coating mechanism and effectively coat the product in the lower mold; the lower mold flipping cylinder can drive the lower mold frame, the lower mold on the lower mold frame, and the film coating mechanism to flip, so as to unload the product and improve the operability and production efficiency of the loading mold;

[0016] The laminating mechanism allows the film on the film roll to be hung on the needles on the synchronous belt. The film on the film roll is driven by a motor to rotate the synchronous pulley, which in turn drives the synchronous belt to rotate. This allows the end of the film to move along the synchronous belt from one end of the lower mold to the other end. When it reaches the other end, the motor stops running, and the telescopic guide post assembly and cylinder assembly move the film down to cover the lower mold. The cutting mechanism then cuts the film, thereby increasing the laminating speed of the laminating mechanism. This solves the problem in the existing technology where the laminating mechanism requires another process to coat the product, which seriously increases production costs and product forming time.

[0017] The gear lifting mechanism allows the inner side plates of the two vertical frames of the machine frame and the fixed plate between the side plates to move up and down via the main cylinder. The gears on the two second rotating shafts at both ends of the side plates drive the rack gears on the outer sides of the two vertical frames of the machine frame, so that the upper mold frame connected to the side plates via the connecting shaft can move up and down smoothly within the machine frame, thereby improving the stability of the upper mold frame's up and down movement.

[0018] The second shaft of the membrane roll is connected to a wrench at one end, which allows the membrane on the roll to be manually adjusted to align with the needles on the timing belt when the membrane cannot be punctured on the timing belt, thus facilitating the use of the membrane.

[0019] The outer wall of the side plate is provided with several bearing seats for the second rotating shaft to pass through, which can adjust the height of the second rotating shaft of the gear lifting mechanism to meet production requirements. Attached Figure Description

Detailed Implementation

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In one specific embodiment of this utility model, such as Figures 1-3As shown, a flip-type loading mold with a film coating mechanism is disclosed, including a frame 1, an upper mold frame 2, an upper mold flipping cylinder 3, a lower mold frame 4, and a film coating mechanism 5. Gear lifting mechanisms 6 are provided on both vertical frames 11 of the frame 1. The two ends of the upper mold frame 2 are respectively connected to the two gear lifting mechanisms 6 through connecting shafts 7. A fixing plate 8 is provided between the two gear lifting mechanisms 6. The fixing plate 8 is located on the side away from the connecting shaft 7 and above the upper mold frame 2. Preferably, there are two upper mold flipping cylinders 3. The two upper mold flipping cylinders 3 are obliquely fixed on the fixing plate 8, and their output ends are tilted towards the side close to the connecting shaft 7 and connected to the upper mold frame 2. An upper mold is installed at the bottom of the upper mold frame 2.

[0027] One side of the lower mold frame 4 is connected to the frame 1 via several first rotating shafts 9. Several lower mold tilting cylinders are obliquely installed inside the frame 1 to drive the lower mold frame 4 to tilt. The output ends of the several lower mold tilting cylinders are inclined away from the first rotating shafts 9 and connected to the bottom of the lower mold frame 4. Preferably, there are two lower mold tilting cylinders. The film coating mechanism 5 is connected to two connecting plates 103 via several telescopic guide column assemblies 10. The two connecting plates 103 are connected to the top of the lower mold frame 4 and are located below the upper mold frame 2. The lower mold is installed on the lower mold frame 4. The film coating mechanism 5, driven by the several telescopic guide column assemblies 10, applies the film to the product inside the lower mold.

[0028] There are at least four telescopic guide post assemblies 10, which are symmetrically arranged on two connecting plates 103. Each telescopic guide post assembly 10 includes a first fixing seat 101 and a telescopic guide post 102. The first fixing seat 101 is fixedly arranged on the connecting plate 103, and the telescopic guide post 102 is fixedly arranged at the bottom of the film covering mechanism 5, and its telescopic end extends into the first fixing seat 101 and is fixed by fasteners.

[0029] The film coating mechanism 5 includes a set of linear guide rails 51, four synchronous pulleys 52, two synchronous belts 53, a film roll 54, and a motor. The set of linear guide rails 51 are symmetrically arranged on the top of the telescopic guide column 102. The four synchronous pulleys 52 are arranged in pairs, and each pair of synchronous pulleys 52 is respectively arranged on the inner side of both ends of each linear guide rail 51. Each synchronous belt 53 is respectively sleeved on each pair of synchronous pulleys 52. The film roll 54 is arranged on one side of a set of linear guide rails 51 and on one side of the synchronous belt 53. Several needles 531 for dragging the film are evenly distributed on the outer wall of the synchronous belt 53. The motor is mounted on the linear guide rails 51, and its output shaft is connected to the shaft of one of the pairs of synchronous pulleys 52.

[0030] A mounting base 13 is provided on one side of a set of linear guide rails 51. A membrane roll 54 is installed in the mounting base 13 through a second rotating shaft. One end of the second rotating shaft passes through one side wall of the mounting base 13 and is connected to a wrench 14. The membrane roll 54 is set perpendicular to the linear guide rails 51. A cutting mechanism 12 is provided on the set of linear guide rails 51. The cutting end of the cutting mechanism 12 is located above the synchronous belt 53.

[0031] The design of connecting a wrench 14 to one end of the second rotating shaft of the membrane roll 54 allows for manual adjustment to make the membrane on the membrane roll 54 align with the needles 531 on the timing belt 53 when the membrane cannot be aligned with them, thus facilitating the use of the membrane.

[0032] The film coating mechanism 5 is designed so that the film on the film roll 54 can be hung on the needle 531 on the synchronous belt 53. The film on the film roll 54 is driven by the synchronous wheel 52 to rotate, which in turn drives the synchronous belt 53 to rotate. This allows the end of the film to move along the synchronous belt 53 from one end of the lower mold to the other end. When it reaches the other end, the motor stops running, and the telescopic guide post assembly 10 and the cylinder assembly 15 move the film down to cover the lower mold. Then the cutting mechanism 12 cuts it, thereby increasing the film coating speed of the film coating mechanism 5.

[0033] A plurality of cylinder assemblies 15 are provided between the linear guide rail 51 and the connecting plate 103. Preferably, there are four cylinder assemblies 15. Each cylinder assembly 15 includes a second fixed seat 151 and a cylinder 152. The second fixed seat 151 is fixedly disposed at the bottom of the linear guide rail 51, and the cylinder 152 is fixedly disposed on the connecting plate 103. The output end of the cylinder 152 passes through the second fixed seat 151 and is locked by fasteners.

[0034] Each gear lifting mechanism 6 includes a main cylinder 61, a side plate 62, and a rack 63. The main cylinder 61 is installed inside the vertical frame 11 of the frame 1, and its output end is connected to the side plate 62 through a connecting seat. One side of the side plate 62 is connected to one end of the fixed plate 8. The rack 63 is vertically installed on both sides of the vertical frame 11 of the frame 1. Several bearing seats 66 for the third rotating shaft 64 are spaced through the outer wall of each side plate 62. One side of the side plate 62 of each gear lifting mechanism 6 is provided with a self-locking mechanism that locks with the upper mold frame 2 to avoid the problem of easy displacement after the upper mold frame 2 is reset.

[0035] The two ends of the fixed plate 8 are respectively fixed to the side plates 62 of the two gear lifting mechanisms 6. Several bearing seats 66 for the third rotating shaft 64 are provided at intervals on the outer wall of the side plate 62, so that the height of the third rotating shaft 64 of the gear lifting mechanism 6 can be adjusted to meet the production requirements.

[0036] Two third rotating shafts 64 are respectively inserted between the two ends of the side plates 62 of the two gear lifting mechanisms 6. The two ends of the two third rotating shafts 64 extend out of the side plates 62 on both sides and are fitted with gears 65. The gears 65 are configured to cooperate with the corresponding racks 63.

[0037] The gear lifting mechanism 6 allows the side plates 62 on the inner side of the two vertical frames 11 of the frame 1 and the fixed plate 8 between the side plates 62 to move up and down via the main cylinder 61. The gears 65 on the two third rotating shafts 64 at both ends of the side plates 62 drive the racks 63 and gears 65 on the outer side of the two vertical frames 11 of the frame 1, so that the upper mold frame 2 connected to the side plates 62 via the connecting shaft 7 can move up and down smoothly within the frame 1, thereby improving the stability of the upper mold frame 2's up and down movement.

[0038] In this invention, the loading mold, through the upper mold tilting cylinder 3 and the gear lifting mechanism 6, enables the upper mold frame 2 to achieve both tilting and vertical movement, effectively improving the multi-functionality of the upper mold frame 2. The film coating mechanism 5 can be driven to move up and down by the cylinder assembly 15, and at the same time, the telescopic guide column 102 of the telescopic guide column assembly 10 extends and retracts simultaneously to improve the operational stability of the film coating mechanism 5. Meanwhile, the lower mold tilting cylinder can effectively drive the lower mold frame 4 and the lower mold on the lower mold frame 4, as well as the film coating mechanism 5, to tilt, so as to facilitate product unloading and improve the operability and production efficiency of the loading mold.

[0039] The working process of this utility model is as follows:

[0040] Two lower mold tilting cylinders drive the lower mold frame 4 to tilt towards the first rotating shaft 9. After tilting, the lower mold is installed. After the lower mold is installed, the two lower mold tilting cylinders drive the lower mold frame 4 to reset. Then, the telescopic guide post assembly 10 and the cylinder assembly 15 are installed under a set of linear guide rails 51 of the film coating mechanism 5. The telescopic guide post 102 of the telescopic guide post assembly 10 is fixed to the bottom of a set of linear guide rails 51, and its telescopic end extends into the first fixed seat 101 on the connecting plate 103 and is locked by fasteners. The cylinder 152 of the cylinder assembly 15 is fixed on the connecting plate 103, and its output shaft passes through the second fixed seat 151 at the bottom of the linear guide rail 51 and is locked by fasteners. After installation, the film coating mechanism 5 is positioned above the lower mold. The upper mold tilting cylinder 3 drives the upper mold frame 2 to tilt downward. When the upper mold frame 2 tilts to a vertical position, the upper mold is installed on the upper mold frame 2. After installation, the upper mold tilting cylinder 3 drives the upper mold frame 2 to reset.

[0041] During molding, the robotic arm sprays foaming resin into the lower mold. The main cylinder 61 drives the side plates 62 on both sides to move downwards. The gears 65 at the ends of the two second rotating shafts at both ends of the two side plates 62 rotate downwards on the rack 63. At the same time, the upper mold frame 2 and the upper mold move downwards to close with the lower mold to obtain the desired product. After the product is formed, the upper mold is lifted. The film on the film roll 54 of the film coating mechanism 5 is pierced onto the needles 531 of the synchronous belt 53 by rotating the second rotating shaft of the film roll 54 with a wrench. The motor is started, and the motor drives the synchronous pulley 52 and the synchronous belt 53 to rotate, so as to move the end of the film from one end of the lower mold to the next end. When the motor stops, the cutting mechanism 12 is activated to cut the film. Then, the film coating mechanism 5 moves downward under the drive of the cylinder assembly 15, and at the same time, the telescopic end of the telescopic guide post assembly 10 extends and retracts, so that the film coating mechanism 5 moves downward steadily so that the film is applied to the lower mold and then to the product. The upper mold then presses down again to apply the film to the product, and the product forming is completed. This improves the film coating speed of the film coating mechanism 5 and also allows for loading and unloading of the mold and product by flipping it up and down. It also solves the problem in the prior art that the film coating requires another process film coating mechanism to apply the film to the product, which seriously increases the production cost and product forming time.

[0042] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
