Description

Technical Field

[0001] This utility model relates to the field of industrial mold technology, and in particular to a multi-clipped cloth sealing mold. Background Technology

[0002] Fabric-reinforced rubber products, especially flat diaphragms, are widely used in pneumatic transmission, hydraulic transmission, and various sealing applications due to the excellent dimensional stability and tensile strength provided by their fabric skeleton layer. The performance of these products, particularly their thickness uniformity, structural density, and fatigue life, directly determines the operational reliability and long-term durability of the entire sealing system, making them key components for ensuring the stable operation of industrial equipment.

[0003] However, in the current production process of fabric-reinforced rubber products such as flat diaphragms, which require extremely high uniformity of thickness, the mainstream mold design and production mode still generally adopts the traditional form of "one mold, one cavity" or "one product per batch"—that is, in a single vulcanization cycle, one set of molds can only produce one finished product. This mode has significant limitations: on the one hand, the utilization rate of equipment in a single production cycle is extremely low, with a large amount of time consumed in mold opening and closing and single product forming; on the other hand, the production cost per unit of finished product remains high, and the energy consumption during the production process is large, making it difficult to adapt to the urgent needs of modern industrial production for high-efficiency, low-cost, and low-energy manufacturing, thus restricting the large-scale and intensive development of the fabric-reinforced sealing parts industry.

[0004] Therefore, it is necessary to address the aforementioned issues with a multi-clipped fabric seal mold. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-clip cloth sealing mold.

[0006] This utility model is achieved using the following technical solution: a multi-component fabric-reinforced sealing mold, comprising: a lower mold base and an upper mold base located above the lower mold base, a detachable middle plate provided between the lower mold base and the upper mold base, at least two injection grooves for molding products being provided through the middle plate, a lower mold core plate fixedly provided on the side of the lower mold base facing the middle plate, and an upper mold core plate fixedly provided on the side of the upper mold base facing the middle plate, wherein the number, position and shape of the lower mold core plate and the upper mold core plate are adapted to the injection grooves on the middle plate one by one, and the end of the lower mold core plate away from the lower mold base and the end of the upper mold core plate away from the upper mold base can be respectively embedded into the injection grooves, together forming a sealed mold cavity for molding fabric-reinforced sealing components.

[0007] As a further improvement to the above solution, a connecting seat is rotatably mounted on the lower mold core plate, a threaded ring is installed at the bottom of the connecting seat, an adjustment groove is opened on the lower mold base, and an installation seat is slidably installed in the adjustment groove. The connecting seat is threadedly connected to the installation seat through the threaded ring.

[0008] As a further improvement to the above solution, a return spring is fitted on the mounting base. One end of the return spring is connected to the mounting base, and the other end of the return spring is connected to the inner wall of the adjustment groove. The return spring is used to increase the stability between the mounting base and the adjustment groove.

[0009] As a further improvement to the above solution, multiple annular wave grooves are provided on the outer side of the connecting seat.

[0010] As a further improvement to the above solution, a pneumatic flow channel is provided on the lower mold base, which is connected to the adjustment groove. A mounting groove is provided on the lower mold base, and an adjustment air cylinder is installed in the mounting groove. An electric push rod is installed in the mounting groove, and an annular piston is installed in the adjustment air cylinder. The telescopic shaft of the electric push rod extends into the adjustment air cylinder and is connected to the annular piston to drive the annular piston to move back and forth.

[0011] As a further improvement to the above solution, an annular groove is provided on the outer side of the mounting base, and a sealing ring is provided in the annular groove. The outer side of the sealing ring contacts the inner wall of the adjustment groove to increase the sealing between the mounting base and the adjustment groove.

[0012] As a further improvement to the above solution, an installation groove is provided on the upper mold base, and a protrusion is provided on the upper mold core plate. The protrusion extends into the installation groove and is threadedly connected to the installation groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared to the traditional "one mold, one cavity" or "one-to-one" production methods, this method adds a semi-finished product manufacturing process. First, semi-finished products are produced, and then finished products are made from them. This method achieves a "one-to-many" production model, improving production efficiency. Specifically, a middle plate is set up with multiple injection grooves. Then, an upper mold core plate and a lower mold core plate are set up and extended into the injection grooves, forming a mold cavity for injection molding. This ensures the quality of the produced flat film, and the single semi-finished product can be used to make multiple finished products in subsequent production processes, thus achieving the effect of "one-to-many". By setting the upper mold core plate, lower mold core plate, and middle plate independently, the replacement of the upper mold core plate, lower mold core plate, and middle plate can be completed quickly. In this state, the corresponding production components can be replaced in a timely manner according to the size requirements of the flat film to be produced, without the need to replace the upper mold base and lower mold base, which improves production efficiency and saves production costs. By making the lower mold core plate movable, the airflow in the air cylinder can be adjusted by an electric push rod and annular piston after production, thereby adjusting the position of the lower mold core plate. This allows the finished product to be quickly pushed to the top of the middle plate for easy handling, thus indirectly improving production efficiency. Attached Figure Description

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] Please combine Figures 1 to 5 The core components include the lower mold base 1, the upper mold base 2, the middle plate 3, the lower mold core plate 5, and the upper mold core plate 9. These components work together to achieve simultaneous production of multiple products and flexible product changeover. The specific structure is as follows: The upper mold base 2 is positioned directly above the lower mold base 1, with a middle plate 3 placed horizontally between them. Several injection through slots are provided on the middle plate 3. The lower mold core plate 5 is fixedly mounted on the top of the lower mold base 1, and the upper mold core plate 9 is fixedly mounted on the bottom of the upper mold base 2. The shape and size of the lower mold core plate 5 and the upper mold core plate 9 are precisely matched with the injection through slots.

[0018] The number of injection molding channels, lower mold core plate 5, and upper mold core plate 9 can be flexibly set according to actual production needs (such as 2-8), realizing simultaneous injection molding of multiple products; at the same time, the three are set independently of the lower mold base 1 and the upper mold base 2, so there is no need to disassemble the entire mold base when changing, which greatly reduces the cost and time of changeover.

[0019] The bottom of the lower mold core plate 5 is rotatably mounted with a connecting seat 6. The outer side of the connecting seat 6 has 3-5 annular wave grooves (to facilitate the operator to rotate it by hand), and the top diameter of the connecting seat 6 is slightly smaller than that of the lower mold core plate 5 (to avoid assembly interference). The bottom of the connecting seat 6 is fixedly connected with a threaded ring 8, and the top of the lower mold base 1 is correspondingly provided with an adjustment groove 4. The mounting seat 7 is slidably assembled in the adjustment groove 4, and the connecting seat 6 is threadedly connected to the mounting seat 7 through the threaded ring 8.

[0020] The bottom of the lower mold core plate 5 is provided with 2-4 positioning blocks, and the top of the mounting base 7 is provided with a corresponding positioning slot. During assembly, the positioning blocks are first inserted into the positioning slot to ensure that the coaxiality error between the lower mold core plate 5 and the mounting base 7 is smaller. A return spring is fitted on the outer side of the mounting base 7. One end of the return spring abuts against the stepped surface in the middle of the mounting base 7, and the other end abuts against the stepped surface of the inner wall of the adjusting groove 4. When there is no external force, the spring force can apply a downward preload to the mounting base 7 to prevent the mounting base 7 from moving during the injection molding process.

[0021] An annular groove is provided on the outer side of the mounting base 7, and a rubber sealing ring is embedded in the groove. The outer side of the sealing ring is tightly fitted with the inner wall of the adjustment groove 4 to ensure the air pressure sealing in the adjustment groove 4 and to avoid air pressure leakage from affecting the position adjustment accuracy.

[0022] The lower mold base 1 has an air pressure channel 10 inside. One end of the air pressure channel 10 is connected to the bottom of the adjustment groove 4, and the other end extends into the mounting groove on the side of the lower mold base 1. An adjustment air cylinder 12 and an electric push rod 13 are fixedly installed in the mounting groove. An annular piston is slidably installed in the adjustment air cylinder 12. The telescopic shaft of the electric push rod 13 passes through the end cap of the adjustment air cylinder 12 and is fixedly connected to the center of the annular piston, which can drive the annular piston to move back and forth along the axis of the adjustment air cylinder 12.

[0023] When the electric push rod 13 extends or retracts, it changes the volume of the regulating cylinder 12 through the annular piston, and then regulates the air pressure in the regulating groove 4 through the air pressure flow channel 10. When the air pressure in the regulating groove 4 increases, it pushes the mounting seat 7 to move upward, causing the lower mold core plate 5 to rise synchronously. When the air pressure decreases, the mounting seat 7 returns to its original position under the action of the return spring, thereby realizing the position adjustment of the lower mold core plate 5.

[0024] The bottom of the upper mold base 2 is provided with a concave mounting groove, and the top of the upper mold core plate 9 is fixedly provided with a convex ring block. The convex ring block and the concave mounting groove are connected by threads to ensure the assembly accuracy of the upper mold core plate 9.

[0025] The upper mold base 2 has an injection flow channel 11 inside. One end of the injection flow channel 11 is connected to the nozzle of the external injection molding machine, and the other end extends vertically to the bottom of the upper mold core plate 9 (connected to the injection channel). The inner diameter of the injection flow channel 11 gradually decreases from the inlet to the outlet to ensure that the molten material is injected smoothly into the injection channel.

[0026] By setting up the middle plate 3, the lower mold core plate 5, and the upper mold core plate 9, multiple products can be produced simultaneously, improving production efficiency. At the same time, the independent setting of the middle plate 3, the lower mold core plate 5, and the upper mold core plate 9 also provides convenience for producing different types of flat films, without the need to completely disassemble and replace the lower mold base 1 and the upper mold base 2, thus saving costs.

[0027] A connecting seat 6 is rotatably mounted on the lower mold core plate 5. A threaded ring 8 is installed at the bottom of the connecting seat 6. An adjustment groove 4 is provided on the lower mold base 1. An installation seat 7 is slidably installed in the adjustment groove 4. The connecting seat 6 is threadedly connected to the installation seat 7 through the threaded ring 8. A positioning block is installed on the lower mold core plate 5. A positioning slot is provided on the installation seat 7. During installation, the positioning block is first inserted into the positioning groove, thereby ensuring the installation accuracy of the lower mold core plate 5.

[0028] By setting up the connecting seat 6, the threaded ring 8 and the mounting seat 7, the lower mold core plate 5 and the lower mold base 1 can be detached, which makes it convenient to replace the lower mold core plate 5.

[0029] A return spring is fitted on the mounting base 7. One end of the return spring is connected to the mounting base 7, and the other end of the return spring is connected to the inner wall of the adjustment groove 4. The return spring is used to increase the stability between the mounting base 7 and the adjustment groove 4.

[0030] By setting a return spring, a downward pressure can be applied to the mounting base 7 even when it is not affected by external forces, thereby increasing the placement stability of the mounting base 7.

[0031] The outer side of the connecting seat 6 is provided with multiple annular wave grooves, and the top diameter of the connecting seat 6 is smaller than the diameter of the lower mold core plate 5.

[0032] The above technical solution allows operators to easily rotate the connecting seat 6, improving the installation efficiency of the lower mold core plate 5.

[0033] The lower mold base 1 is provided with a pneumatic flow channel 10, which is connected to the adjustment groove 4. The lower mold base 1 is provided with a mounting groove, in which an adjustment air cylinder 12 is provided. An electric push rod 13 is installed in the mounting groove. An annular piston is provided in the adjustment air cylinder 12. The telescopic shaft of the electric push rod 13 extends into the adjustment air cylinder 12 and is connected to the annular piston to drive the annular piston to move back and forth.

[0034] The annular piston is moved by the telescopic shaft of the electric push rod 13. The regulating groove 4 is connected to the regulating air cylinder 12 through the air pressure channel 10. The air pressure in the regulating groove 4 can be indirectly adjusted. The position of the mounting seat 7 is adjusted by changing the air pressure, and then the position of the lower mold core plate 5 is adjusted.

[0035] The mounting base 7 has an annular groove on its outer side, and a sealing ring is provided in the annular groove. The outer side of the sealing ring contacts the inner wall of the adjusting groove 4. The sealing ring is made of rubber.

[0036] By setting a sealing ring, a sealing medium can be placed between the mounting base 7 and the adjusting groove 4, thereby increasing the sealing performance between the mounting base 7 and the adjusting groove 4.

[0037] The upper mold base 2 is provided with an installation groove, and the upper mold core plate 9 is provided with a protrusion. The protrusion extends into the installation groove and is threadedly connected to the installation groove. The upper mold base 2 is provided with an injection flow channel 11, one end of which extends to the upper mold core plate 9 to facilitate injection molding operations.

[0038] By using a concave mounting groove and a convex ring for the protrusion, the mounting groove has a positioning effect when the protrusion is installed, thus ensuring the installation accuracy of the upper mold core plate 9.

[0039] The implementation principle of a multi-pronged fabric-retaining seal mold in this application embodiment is as follows: Install the lower mold base 1 and the upper mold base 2 respectively, then select the appropriate middle plate 3 and lower mold core plate 5 to install on the lower mold base 1, and select the appropriate upper mold core plate 9 to install on the upper mold base 2; the specific installation operation is as follows: insert the threaded ring 8 on the connecting seat 6 into the mounting seat 7, and then rotate the connecting seat 6 to make the threaded ring 8 and the mounting seat 7 threadedly connected until the connecting seat 6 contacts the top of the lower mold base 1. Similarly, install the upper mold core plate 9 onto the upper mold base 2 through the protrusion thread, and then place the middle plate 3 on the lower mold base 1 so that the lower mold core plate 5 extends into the injection groove on the middle plate 3; During production, the upper mold base 2, the middle plate 3, and the lower mold base 1 are connected so that the lower mold core plate 5 and the upper mold core plate 9 both extend into the injection groove on the middle plate 3. Then, the injection molding operation is carried out through the injection runner 11. After the injection molding is completed, the upper mold base 2 is returned to its initial state. Then, the electric push rod 13 is activated to push the annular piston to move. The airflow pushes the mounting seat 7 to rise, which in turn pushes the lower mold core plate 5 to rise, pushing the injection molded product above the middle plate 3 for easy handling and improved production efficiency.
