[0002] The hydraulic foaming mold frame for automotive interior parts is a piece of equipment used for polyurethane foaming. It mainly consists of upper and lower mold frames, a locking mechanism, and a hydraulic drive system. It can realize mold closing and flipping, ensuring the safe foaming production of automotive interior parts.

[0003] The existing hydraulic foaming mold frame has a problem when it is working: the mold frame opening angle is too small, and the mold frame cannot be fully opened, which makes the equipment for grabbing foamed products from the mold unable to operate normally and affects the production progress. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a 180° rotating hydraulic mold frame. The specific technical solution is as follows:

[0005] This utility model provides a 180° rotating hydraulic mold frame, including a horizontally arranged base. Support legs are symmetrically fixed at both ends of one long side of the base, and support rods are symmetrically fixed to the outer sides of the two support legs. Support seats are symmetrically fixed at both ends of the other long side. Upper mold rotating cylinders are symmetrically inserted laterally through the tops of the two support seats. Rotating lugs are symmetrically fixedly fitted axially at the rotating ends of the two upper mold rotating cylinders facing the inner side of the corresponding support seats. An upper mold frame is horizontally supported between the two rotating lugs. The two ends of the upper mold frame facing away from the rotating lugs are detachably locked to the tops of the corresponding support rods. The upper mold frame can be rotated 180° to the corresponding long side of the base by the two upper mold rotating cylinders.

[0006] The base has a horizontally limited lower mold tilting frame on its top surface. The lower mold frame is horizontally supported by multiple vertically evenly distributed elastic guide components. The base also has multiple vertically evenly distributed mold closing and lifting cylinders for lifting the lower mold frame.

[0007] As a preferred technical solution of this utility model, the long side of the lower mold flipping frame facing the support foot is hinged to the long side of the base. The lower mold flipping frame and the base are symmetrically hinged along the center line with lower mold flipping cylinders. The lower mold flipping frame can be driven by two lower mold flipping cylinders to achieve a 90° flip to the long side of the base.

[0008] As a preferred technical solution of this utility model, the other long side of the lower mold flipping frame is detachably connected to the corresponding long side of the base by at least two buckles.

[0009] As a preferred technical solution of this utility model, the elastic guide component includes a guide rod that is vertically spaced through the lower mold flipping frame. The top end of the guide rod is fixedly connected to the bottom surface of the lower mold frame, and the bottom end is axially connected to a limiting piece by bolts. A spring is axially sleeved on the guide rod. The top end of the spring is connected to the bottom surface of the lower mold flipping frame, and the bottom end is connected to the top surface of the limiting piece.

[0010] As a preferred technical solution of this utility model, the two ends of the long side of the upper mold frame facing away from the flip-up support are respectively symmetrically fixed with locking grooves of L-shaped structure. The groove of the locking groove is engaged with the corresponding locking block that is vertically fixed to the top of the support rod, and the two are locked together by a pin provided at the corresponding long side end of the upper mold frame.

[0011] As a preferred technical solution of this utility model, the bottom surface of the upper mold frame and the top surface of the lower mold frame are respectively provided with multiple mold mounting grooves with T-shaped longitudinal sections symmetrically inward along their respective long sides.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, the upper mold tilting cylinder directly drives the upper mold frame to tilt 180° via tilting lugs, completely separating the upper mold frame from the lower mold area and tilting it to the long side of the base, instead of the traditional small-angle mold opening. This 180° tilting design ensures the mold frame is fully open, providing unobstructed operating space for the gripping equipment. It avoids the interference problem caused by the excessively small opening angle of the mold frame in existing technologies, enabling the equipment for gripping foamed products to operate smoothly and reducing the risk of product damage. Simultaneously, the tilting action is controlled by a hydraulic system, ensuring stability and reliability, and improving production continuity and safety.

[0014] 2. In this utility model, the mold-closing lifting cylinders are vertically and evenly distributed. By lifting the lower mold frame, the lower mold frame overcomes the elastic resistance of the elastic guide component and moves upward to close with the upper mold frame. The elastic guide component provides guidance and cushioning. This structure ensures smooth movement and accurate guidance of the lower mold frame during mold closing, avoiding mold misalignment or wear caused by hard impacts. The elastic guide component absorbs some vibration and pressure, ensuring uniform contact between the upper and lower molds, improving the dimensional consistency and surface quality of the foamed products. Simultaneously, it reduces the frequency of mold maintenance and extends the service life of the equipment.

[0015] 3. In this utility model, the base adopts a symmetrical support design of support feet and support seats. The upper mold frame is fixed to the top of the support rod through a detachable locking mechanism when the mold is closed; after flipping, the upper mold frame is completely released. This symmetrical support structure provides overall rigidity, preventing shaking during mold closing or flipping, and ensuring production stability. The detachable locking mechanism facilitates locking and unlocking of the upper mold frame, and combined with 180° flipping, makes mold replacement or maintenance more convenient, reducing production downtime. In addition, after flipping, the upper mold frame is located on the side of the base, which does not affect the operation of the lower mold area, supports the integration of automated equipment, and improves production flexibility.

[0016] 4. This utility model employs a hydraulic drive system composed of an upper mold tilting cylinder and a mold closing and lifting cylinder to control the tilting and lifting actions, with programmable operation processes; the lower mold tilting frame is horizontally limited on the base to prevent displacement. This hydraulic drive system provides controllable and stable power output, reducing the risks of manual operation; simultaneously, the horizontal limiting design of the lower mold tilting frame ensures that the lower mold frame does not shift during lifting, simplifying the operation process and improving human-machine collaboration efficiency.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0023] Example 1

[0024] To address the technical problems in the background section, a 180° rotating hydraulic mold frame is provided as follows:

[0025] Combination Figures 1-4 As shown, a 180° rotating hydraulic mold frame includes a horizontally arranged base 1. Support legs 11 are symmetrically fixed at both ends of one long side of the base 1, and support rods 12 are symmetrically fixed to the outer surfaces of the two support legs 11. Support seats 2 are symmetrically fixed at both ends of the other long side. Upper mold rotating cylinders 3 are symmetrically inserted laterally through the tops of the two support seats 2. Rotating ears 31 are symmetrically fixedly sleeved axially at the rotating ends of the two upper mold rotating cylinders 3 facing the inner side of the corresponding support seats 2. An upper mold frame 4 is horizontally mounted between the two rotating ears 31. The two ends of the long side of the upper mold frame 4 away from the rotating ears 31 are detachably locked to the tops of the corresponding support rods 12. The upper mold frame 4 can be rotated 180° to the corresponding long side of the base 1 by the two upper mold rotating cylinders 3.

[0026] The base 1 is horizontally limited by a lower mold flipping frame 5. The lower mold frame 6 is horizontally supported by multiple vertically evenly distributed elastic guide components 7. The base 1 is also vertically evenly distributed with multiple mold closing and lifting cylinders 9 for lifting the lower mold frame 6.

[0027] In the above technical solution, the upper mold tilting cylinder 3 in the hydraulic mold frame directly drives the upper mold frame 4 to tilt 180° via the tilting support 31, so that the upper mold frame 4 is completely separated from the lower mold area and tilted to the long side of the base 1, instead of the traditional small-angle mold opening. This 180° tilting design ensures that the mold frame is fully opened, providing unobstructed operating space for the gripping equipment. It avoids the interference problem caused by the excessively small opening angle of the mold frame in the prior art, enabling the equipment for gripping foamed products to operate smoothly and reducing the risk of product damage. At the same time, the tilting action is controlled by the hydraulic system, which is stable and reliable, improving production continuity and safety.

[0028] In this hydraulic mold frame, the mold-closing and lifting cylinders 9 are vertically and evenly distributed. By lifting the lower mold frame 6, the lower mold frame 6 overcomes the elastic resistance of the elastic guide component 7 and moves upward to close with the upper mold frame 4. The elastic guide component 7 provides guidance and cushioning. This structure ensures smooth movement and accurate guidance of the lower mold frame 6 during mold closing, avoiding mold misalignment or wear caused by hard impacts. The elastic guide component 7 absorbs some vibration and pressure, ensuring uniform contact between the upper and lower molds, improving the dimensional consistency and surface quality of the foamed products. Simultaneously, it reduces the frequency of mold maintenance and extends the service life of the equipment.

[0029] In this hydraulic mold holder, the base 1 adopts a symmetrical support design with support feet 11 and support seats 2. The upper mold holder 4 is fixed to the top of the support rod 12 via a detachable locking mechanism during mold closing; after flipping, the upper mold holder 4 is completely released. This symmetrical support structure provides overall rigidity, preventing swaying during mold closing or flipping, and ensuring production stability. The detachable locking mechanism facilitates locking and unlocking of the upper mold holder 4, and combined with 180° flipping, makes mold replacement or maintenance more convenient, reducing production downtime. Furthermore, after flipping, the upper mold holder 4 is located on the side of the base 1, not affecting the operation of the lower mold area, supporting integration with automated equipment, and improving production flexibility.

[0030] The hydraulic mold frame uses a hydraulic drive system consisting of an upper mold tilting cylinder 3 and a mold closing and lifting cylinder 9 to control the tilting and lifting actions, and the action process is programmable. The lower mold tilting frame 5 is horizontally limited on the base 1 to prevent displacement. This hydraulic drive system provides controllable and stable power output, reducing the risk of manual operation; at the same time, the horizontal limit design of the lower mold tilting frame 5 ensures that the lower mold frame 6 does not shift during the lifting process, simplifying the operation process and improving the efficiency of human-machine collaboration.

[0031] This hydraulic mold frame achieves complete rotation of the upper mold frame 4 through the upper mold tilting cylinder 3, directly solving the problem of insufficient mold frame opening angle causing operational obstacles to the gripping equipment in existing technologies, and significantly improving production efficiency. Simultaneously, combined with the elastic guide component 7, the mold closing and lifting cylinder 9, and the detachable locking mechanism, this solution produces synergistic technical effects in terms of mold closing accuracy, equipment stability, safety, and ease of maintenance.

[0032] like Figure 1 and Figure 3 As shown, the elastic guide assembly 7 includes a guide rod 71 that passes vertically through the lower mold flipping frame 5. The top end of the guide rod 71 is fixedly connected to the bottom surface of the lower mold frame 6, and the bottom end is axially connected to a limit piece 73 by bolts. A spring 72 is axially sleeved on the guide rod 71. The top end of the spring 72 is connected to the bottom surface of the lower mold flipping frame 5, and the bottom end is connected to the top surface of the limit piece 73.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the upper mold frame 4 has locking grooves 41 with L-shaped openings symmetrically fixed at both ends of the long side away from the flip-up support ear 31. The opening of the locking groove 41 is engaged with the locking block 121 that is vertically fixed to the top of the support rod 12, and the two are locked together by a pin 42 provided at the corresponding long side end of the upper mold frame 4.

[0034] like Figure 1 and Figure 2As shown, the bottom surface of the upper mold frame 4 and the top surface of the lower mold frame 6 are respectively provided with multiple mold mounting grooves 10 with T-shaped longitudinal sections symmetrically inward along their respective long sides.

[0035] In the above technical solution, the structural design of the elastic guide component 7 ensures a smooth and buffered mold closing process. When the mold closing lifting cylinder 9 lifts the lower mold frame 6, the spring 72 is compressed to generate elastic resistance, preventing the lower mold frame 6 from instantly and rigidly impacting the upper mold frame 4. The guide rod 71 constrains the vertical movement trajectory of the lower mold frame 6, preventing deviation and ensuring precise alignment of the upper and lower molds, thus improving mold closing accuracy and product dimensional consistency. During mold separation, the mold closing lifting cylinder 9 is depressurized, and the spring 72 releases its elastic force to push the lower mold frame 6 back to its initial position. The spring 72 absorbs the impact vibration of mold closing, reducing the risk of mold wear and frame deformation, making it particularly suitable for high-frequency production scenarios.

[0036] The L-shaped groove of the locking slot 41 and the three-dimensional snap-fit ​​design (horizontal embedding + vertical limiting) of the locking block 121 form a mechanical interlock, which, together with the lateral locking of the pin 42, resists the high-pressure expansion force during the foaming process, prevents displacement or vibration of the upper mold frame 4, and ensures production safety. During mold parting, the pin 42 automatically disengages, and the upper mold frame 4 can be immediately rotated 180° by the tilting cylinder 3. The L-shaped groove provides a guide for disengagement, avoiding mechanical interference and shortening process time. The pin 42 can be electrically or pneumatically driven to reduce manual operation intensity; the modular locking components facilitate replacement and maintenance.

[0037] The T-shaped mold mounting groove 10 slides into the T-shaped edge strip on the mold (not shown in the figure), achieving "push-in and positioning" of the mold. The T-shaped edge strip is fixed by a pressure plate (not shown in the figure), facilitating subsequent disassembly and assembly. Symmetrical slots on both sides ensure balanced force on the mold, preventing unilateral displacement. After the mold is embedded, the T-shaped mold mounting groove 1 can resist horizontal shear forces, preventing mold slippage due to foaming pressure and ensuring product molding quality.

[0038] Example 2

[0039] Combination Figure 1 and Figure 4 As shown, based on the above embodiments, this embodiment further provides the following:

[0040] In this embodiment, as Figure 1 and Figure 4 As shown, the long side of the lower mold flipping frame 5 facing the support foot 11 is hinged to the long side of the base 1. The lower mold flipping frame 5 and the base 1 are symmetrically hinged along the center line with lower mold flipping cylinders 8. The lower mold flipping frame 5 can be driven by two lower mold flipping cylinders 8 to flip 90° to the corresponding long side of the base 1.

[0041] like Figure 1As shown, the other long side of the lower mold flipping frame 5 is detachably connected to the corresponding long side of the base 1 by at least two buckles 51 (the overall buckle structure is not fully shown in the figure).

[0042] In the above technical solution, the piston rod end of the lower mold tilting cylinder 8 is hinged to the inner side of the long side of the hinge of the lower mold tilting frame 5 (near the hinge point with the base 1), and the tail of the lower mold tilting cylinder 8 is hinged to the inner side of the long side of the base 1 facing the support seat 2.

[0043] After the lower mold tilting cylinder 8 pushes the lower mold tilting frame 5 (including the lower mold holder 6) to tilt 90°, the lower mold is completely separated from the space directly above the base 1 and remains in a lateral position, which facilitates cleaning or brushing the inner wall of the mold in the lower mold holder 6. The symmetrical drive of the dual cylinders ensures that the lower mold tilting frame 5 is subjected to balanced force at both ends during the 90° tilting process, avoiding unilateral twisting or jamming.

[0044] The latch 51 securely locks the non-hinged side of the lower mold tilting frame 5 to the base 1, forming a closed force-bearing frame. This resists the upward lifting force of the mold-closing lifting cylinder 9 on the lower mold frame 6, preventing frame vibration or displacement and ensuring mold-closing accuracy. After mold separation, the latch 51 is released (manually or automatically), and the lower mold tilting cylinder 8 can immediately drive the tilting mechanism without additional disassembly steps. This, combined with the unlocking of the upper mold pin 42, creates a coordinated process, shortening the interval between processes.

[0045] Working principle and usage process of this utility model:

[0046] When this utility model is used, it is divided into the following stages:

[0047] 1. Mold installation stage: The upper mold is fixed in the mold mounting groove 10 on the bottom surface of the upper mold frame 4, and the lower mold is fixed in the mold mounting groove 10 on the top surface of the lower mold frame 6. The lower mold frame 6 is horizontally mounted on the lower mold flipping frame 5 through the elastic guide component 7, and the spring 72 is in a pre-compressed state.

[0048] 2. Mold Closing Production Stage: The mold closing lifting cylinder 9 lifts the lower mold frame 6 upwards, the guide rod 71 moves vertically along the lower mold flipping frame 5, and the spring 72 further compresses to buffer the impact force, so that the lower mold and the upper mold fit tightly together. The locking groove 41 of the upper mold frame 4 engages with the locking block 121 at the top of the support rod 12, and the inserted pin 42 locks it laterally to resist the high pressure of foaming.

[0049] 3. Mold splitting and flipping stage: Pull out the pin 42 to unlock the upper mold frame 4; the mold closing and lifting cylinder 9 retracts, and the spring 72 pushes the lower mold frame 6 to reset. Upper mold flipping 180°: The upper mold flipping cylinder 3 drives the flipping lug 31, causing the upper mold frame 4 to flip 180° to the side of the base; Lower mold flipping 90°: Unlock the buckle 51, and the lower mold flipping cylinder 8 pushes the lower mold flipping frame 5 (including the lower mold frame 6) to flip 90° around the hinge point to the other side of the base and stand up, making it easy to clean or paint the inner wall of the lower mold.

[0050] 4. Retrieval and Maintenance Stage: The upper mold frame 4 rotates 180°, allowing the gripping robot to enter the lower mold area without obstruction and retrieve the foamed product. The mold can be quickly assembled and disassembled through the T-shaped mold mounting slot 10; the lower mold frame 6 rotates 90°, allowing workers to perform cleaning or painting operations on the bottom wall of the lower mold from the side.

[0051] 5. Reset Preparation: Lower Mold Reset: The lower mold tilting cylinder 8 pulls the lower mold tilting frame 5 back to the horizontal position, and the buckle 51 locks it in place. Upper Mold Reset: The upper mold tilting cylinder 3 drives the upper mold frame 4 to rotate 180°, the locking groove 41 and the locking block 121 re-engage, and the pin 42 is inserted to lock it in place.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
