Description

Technical Field

[0001] The utility model relates to the technical field of plastic molding and processing, in particular to a water chamber shaping fixture and a water chamber shaping device. Background Art

[0002] The automobile water chamber is a plastic product formed by injection molding. After injection molding, the water chamber parts need to be cooled and shaped to reduce the possibility of deformation of the water chamber parts. The existing cooling methods include cooling in air or cooling in a coolant (generally water). The existing water chamber cooling device can refer to the Chinese patent with announcement number CN216373233U, which discloses an automobile water chamber shaping device. The device includes a water pool and a mounting seat above the water pool. A mounting frame is arranged in the mounting seat. A shaping tool for mounting water chamber parts is arranged at the bottom of the mounting frame. A guide mechanism that can only guide the lifting of the limited mounting frame and a first cylinder that drives the mounting frame to lift and move are arranged on the mounting seat. A second cylinder for pressing the water chamber parts is arranged on the top of the mounting frame, and two second cylinders are arranged at intervals.

[0003] After the worker installs the water chamber part on the shaping tooling, the shaping device is started. The push rod of the second cylinder extends out and abuts against the water chamber part. Then the push rod of the first cylinder extends out, driving the installation frame to descend, so that the shaping tooling and the water chamber part are completely immersed in the cooling water of the pool and start cooling and shaping. Since the water chamber parts that have not been cooled and shaped are easy to deform, the second cylinder cannot apply excessive pressure to compress them. Its function is only to prevent the water chamber parts from floating in the water. The sizes of water chamber parts of different models are different, and the corresponding cylinder feed strokes are also different. The cylinder feed stroke is controlled by a controller, which is essentially to adjust the feed parameters in the controller. The debugging process requires professional training to master, and the learning difficulty and learning cost are high. After the cylinder is frequently used, there will be cumulative errors that affect the accuracy of the extension distance of the cylinder push rod. In order to reduce the impact of the error on production, the cylinder feed stroke needs to be frequently debugged. Therefore, the existing water chamber shaping device needs to frequently adjust the cylinder parameters during later use and the learning difficulty of the debugging process is high, resulting in the existing water chamber shaping device being more troublesome to use. Utility Model Content

[0004] In view of the shortcomings of the existing water chamber shaping devices, the first purpose of the utility model is to provide a water chamber shaping fixture which has simple operation steps and can be applied to water chamber parts of different models.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A water chamber shaping fixture comprises a bottom plate, on which a shaping tool for installing water chamber parts is arranged. The water chamber shaping fixture also comprises a flipping component arranged on the bottom plate and capable of flipping to approach the water chamber part and pressing it, and a limiting component for limiting the rotation of the flipping component when the flipping component presses the water chamber part. A detachable pressing block is arranged on the flipping component, and when the flipping component approaches the shaping tool, the pressing block abuts against the water chamber part. Two groups of flipping components and limiting components are arranged on the bottom plate at intervals.

[0007] By adopting the above scheme, when the flipping component rotates close to the forming fixture, the pressing block can be pressed against the water chamber part for limiting the position, and then the water chamber part can be prevented from floating up in the water by only limiting the rotation of the flipping component with the limiting component. In this scheme, the pressing block only serves to prevent the water chamber part from floating up, and the compression deformation of the pressing block during use can be ignored, that is, it is not easy to produce errors. Compared with the existing water chamber forming device, when the water chamber forming fixture in this scheme replaces water chamber parts of different models, the worker only needs to select a pressing block matching the model to replace the original pressing block to complete the adjustment. The adjustment is easy to learn and can reduce the difficulty of using the water chamber cooling forming device.

[0008] Preferably, a connecting component for rotating the flip component is provided on the bottom plate, the connecting component comprises a connecting seat provided on the bottom plate and a rotating shaft passing through the connecting seat, and the flip component comprises a pressure rod hingedly provided on the rotating shaft.

[0009] Preferably, the pressure block is arranged on the side of the pressure rod facing the shaping tooling, and the pressure block is connected to the pressure rod by a fastener, the fastener includes a bolt, through holes for the bolts to pass through are arranged at intervals on the pressure block, and threaded holes are arranged at intervals on the pressure rod.

[0010] Preferably, the pressure block is made of a non-rigid material.

[0011] By adopting the above scheme, the bolts are more versatile and less difficult to disassemble and replace. It is more convenient to use bolts to fix the pressure blocks in the later stage. The purpose of making the pressure blocks with non-rigid materials is to reduce the possibility of the pressure blocks squeezing and deforming the water chamber parts during the downward pressing of the pressure rod.

[0012] Preferably, the limiting component includes a pad fixed on the base plate and overlapped with the pressure rod when the pressure rod is flipped to approach the forming tooling, a slot provided on the pressure rod, and a limiting member provided on the pad that can be inserted into the slot and limit the flipping of the pressure rod, and the pad is provided with a sliding structure that enables the limiting member to engage or disengage with the slot.

[0013] Preferably, the sliding structure includes a T-slot opened on the upper end surface of the pad, and the limiting member includes a T-screw slidably arranged in the T-slot and a nut arranged on the T-screw, and the diameter of the T-screw is less than or equal to the width of the slot.

[0014] By adopting the above scheme, when the pressure rod is flipped to approach the forming tooling, the worker slides the T-screw into the slot and manually screws the nut until it abuts against the pressure rod to limit the rotation of the pressure rod. This operation is relatively simple and easy to learn, which can reduce the difficulty of operating the water chamber forming device. Considering that the existing water chamber forming device needs to partially sink the installation frame into the water pool during cooling, the end of the cylinder push rod will also be immersed in water. In order to avoid contact between the cylinder body and water, a cylinder with a longer stroke must be selected. The price of the existing cylinder is proportional to the stroke. The longer the stroke, the higher the price. The pressure block, gasket, T-screw and nut in this scheme are all relatively common parts for assembly, which can reduce the manufacturing cost of the water chamber forming device.

[0015] Preferably, a damping gasket is provided between the pressure rod and the connecting seat, and the damping gasket is sleeved on the rotating shaft.

[0016] By adopting the above solution, the damping gasket can keep the pressure rod at the current angle without rotating when no force is applied. When the water chamber parts are formed, the workers flip the pressure rod away from the forming tooling. At this time, after the workers release the pressure rod, the pressure rod will not flip downward by itself, which makes it convenient for the workers to remove the water chamber parts.

[0017] Preferably, an operating rod is provided between the flipping components to drive the two to flip synchronously, and both ends of the operating rod are respectively fixed to the pressure rod.

[0018] By adopting the above solution, workers can operate the two pressure rods to flip them through the operating lever, making the operation steps of the water chamber clamp simpler.

[0019] The second purpose of the utility model is to provide a water chamber shaping device, including a frame and a water pool, a driving cylinder for driving the water pool to rise or fall is arranged under the water pool, the driving cylinder is fixedly connected to the frame, and a water chamber shaping fixture as described in any one of the above schemes is arranged on the frame, and the bottom plate is fixedly arranged on the frame.

[0020] The utility model has significant technical effects due to the adoption of the above technical scheme: in the present scheme, the pressing block only functions to prevent the water chamber parts from floating up, and the compression deformation of the pressing block during use can be ignored, that is, it is not easy to produce errors; compared with the existing water chamber shaping device, when the water chamber shaping fixture in the present scheme replaces water chamber parts of different models, the worker only needs to select a pressing block matching the model to replace the original pressing block to complete the adjustment, the adjustment difficulty is low and easy to learn, and the difficulty of using the water chamber cooling shaping device can be reduced.

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Example

[0033] A water chamber shaping device, according to Figures 1-2 As shown, it includes a frame 18, a driving cylinder 20 is fixedly arranged on the frame 18, the end of the driving cylinder 20 is connected to a water pool 19, the water pool 19 is raised and lowered by the extension and retraction of the driving cylinder 20, a bottom plate 1 is fixedly arranged on the frame 18, and a molding tool 2 for installing a water chamber part 3 is arranged on the bottom plate 1. The above is the prior art.

[0034] The improvement of this embodiment is that the bottom plate 1 is provided with a flip component which can flip to be close to the water chamber part 3 and press it. Figure 3 , Figure 5 or Figure 7As shown, the flipping component is a pressure rod 7, a connecting seat 5 is fixedly arranged on the bottom plate 1, a rotating shaft 6 is passed through the connecting seat 5, and the pressure rod 7 is hingedly arranged on the rotating shaft 6. Figure 7 As shown, a damping gasket 16 is arranged between the pressure rod 7 and the connecting seat 5, and the damping gasket 16 is sleeved on the rotating shaft 6. A detachable pressure block 4 is arranged on the side of the pressure rod 7 facing the shaping tool 2, and the pressure block 4 is connected to the pressure rod 7 by a fastener. Figure 7 As shown, the fastener includes a bolt 10, a through hole 9 for the bolt 10 to pass through is provided on the pressing block 4, and threaded holes 8 are provided at intervals on the pressing rod 7. In this embodiment, the pressing block 4 is made of a rubber block.

[0035] The bottom plate 1 is also provided with a limit component for limiting the turning of the pressure rod 7 when the pressure rod 7 presses the water chamber part 3. Figure 6 As shown in or 9, the limiting component includes a pad 11 fixedly arranged on the bottom plate 1, a T-shaped slot 13 is provided on the upper end surface of the pad 11, a limiting member is slidably arranged in the T-shaped slot 13, and a card slot 12 is provided on the pressure rod 7. When the pressure rod 7 is turned over to approach the shaping tool 2 and overlapped on the pad 11, the limiting member slides and engages and limits the rotation of the pressure rod 7. Fig. 9 As shown, the limiting member includes a T-screw 14 slidably arranged in the T-slot 13 and a nut 15 arranged on the T-screw 14. The diameter of the T-screw 14 is less than or equal to the width of the slot 12. In this embodiment, the cushion block 11 can be directly replaced by a guide rail with a T-slot 13, and a T-screw 14 adapted to the T-slot 13 can be selected.

[0036] according to Figures 1 to 5 As shown, two groups of flipping components and limiting components are arranged on the bottom plate 1 at intervals, and an operating rod 17 for driving the flipping components to flip synchronously is arranged between the flipping components, and both ends of the operating rod 17 are respectively fixed on the pressure rod 7.

[0037] Combined with the above structure, reference Figures 1 to 9 The shaping operation steps of a water chamber shaping device of this embodiment are as follows:

[0038] The worker first installs the water chamber part 3 on the shaping tool 2, and then presses down the operating rod 17 to drive the two pressure rods 7 to flip downward. After the pressure rod 7 overlaps with the cushion block 11, the worker moves the T-screw 14 into the slot 12, and manually screws the nut 15 until the nut 15 abuts against the surface of the pressure rod 7. At this time, the pressure block 4 abuts against the water chamber part 3, and then starts the driving cylinder 20 under the water pool 19. The water pool 19 rises to immerse the water chamber part 3 in water for cooling and shaping.

[0039] When replacing a water chamber part 3 of a different type with the water chamber shaping fixture of this embodiment, the worker only needs to select a pressing block 4 matching the model to replace the original pressing block 4 to complete the adjustment. The adjustment is easy to learn and can reduce the difficulty of using the water chamber cooling shaping device.

[0040] Taking into account that the existing water chamber shaping device needs to partially sink the installation frame into the water pool 19 during cooling, the end of the cylinder push rod will also be immersed in water. In order to avoid the cylinder body of the cylinder from contacting the water, a cylinder with a longer stroke must be selected. The price of the existing cylinder is proportional to the stroke. The longer the stroke, the higher the price. The pressure block 4, the cushion block 11, the T-screw 14 and the nut 15 in this embodiment are all relatively common parts for assembly, which can reduce the manufacturing cost of the water chamber shaping device.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
