Description

Technical Field

[0001] This utility model belongs to the field of injection molding and relates to an injection mold for pressure-resistant and wear-resistant rubber sealing rings. Background Technology

[0002] Injection molds for pressure-resistant and wear-resistant rubber seals are specifically designed for the mass production of these seals with high precision. They employ injection molding technology, injecting the mixed rubber material into the mold cavity under high temperature and pressure, and then rapidly vulcanizing it in a single step. This results in seals with stable dimensions, consistent performance, and excellent pressure and wear resistance. Pressure-resistant and wear-resistant rubber seals are widely used in high-pressure machinery, hydraulic systems, and other applications. Their molding quality directly determines the sealing performance and service life of the equipment; therefore, the precision and adaptability of the injection mold are extremely important.

[0003] Existing rubber sealing ring injection molds generally adopt a fixed cavity structure, and anti-sticking agent is manually sprayed to prevent product adhesion. This method relies on manual operation and is prone to uneven coating, resulting in excessive residue on the surface of hard rubber sealing rings and loss of elasticity in soft rubber sealing rings due to excessive coating thickness. In addition, there is a lack of dynamic adjustment mechanism for rubbers of different hardness, making it difficult to balance the anti-sticking effect with the product's pressure resistance and wear resistance. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an injection mold for pressure-resistant and wear-resistant rubber sealing rings that can automatically spray release agent.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An injection mold for a pressure-resistant and wear-resistant rubber sealing ring includes an injection molding machine frame. The right end of the injection molding machine frame is fixedly connected to an L-shaped side plate. An electric push rod is fixedly connected to the vertical end of the L-shaped side plate near the molding template. A hollow linkage frame is installed at the output end of the electric push rod. A diluent storage tank and a mold release agent storage tank are respectively placed on the front and rear sides of the upper end of the hollow linkage frame. An alcohol outlet pipe extending into the hollow linkage frame is fixedly connected to the lower end of the diluent storage tank. A mold release agent outlet pipe extending into the hollow linkage frame is fixedly connected to the lower end of the mold release agent storage tank. Atomizing nozzles are fixedly connected to the front and rear sides of the lower end of the hollow linkage frame. The upper ends of the two atomizing nozzles are fixedly connected to the corresponding alcohol outlet pipe and mold release agent outlet pipe, respectively. An electric valve block is fixedly connected to the upper ends of both sets of alcohol outlet pipes and mold release agent outlet pipes.

[0007] In the above-mentioned injection mold for pressure-resistant and wear-resistant rubber seals, a hydraulic device is fixedly connected to the upper end of the injection molding machine frame, and a pressure plate is slidably connected to the upper inner wall of the injection molding machine frame.

[0008] In the above-mentioned injection mold for pressure-resistant and wear-resistant rubber sealing rings, a pressure plate II is fixedly connected to the lower inner wall of the injection molding machine frame, and the liquid outlet end of the atomizing nozzle intermittently moves at a uniform speed above the pressure plate II.

[0009] In the above-mentioned injection mold for pressure-resistant and wear-resistant rubber seals, the pressure plate two and the pressure plate one are fixedly connected to a molding template at their close ends, and the output end of the hydraulic device is connected to the pressure plate one.

[0010] In the above-mentioned injection mold for pressure-resistant and wear-resistant rubber sealing rings, multiple electrical valve blocks are respectively installed at the liquid outlet of the diluent storage tank and the release agent storage tank, and the upper end of the hollow linkage frame is symmetrically fixedly connected with ring-shaped storage grooves on both the front and rear sides.

[0011] In the above-mentioned injection mold for pressure-resistant and wear-resistant rubber sealing rings, a weight sensor is fixedly connected to the inner wall of the ring-shaped storage groove, and the diluent tank and the release agent tank are detachably installed in the corresponding ring-shaped storage groove.

[0012] In the aforementioned injection mold for a pressure-resistant and wear-resistant rubber sealing ring, an alarm light is fixedly connected to the side end of the ring-shaped storage groove, and the alarm light and the weight sensor are interconnected by a wire.

[0013] Compared to existing technologies, this injection mold for pressure-resistant and wear-resistant rubber seals integrates a high-efficiency drive and intelligent spraying system to ensure the basic shape and structural integrity of the seal. The anti-stick spraying component achieves automated operation, with a linkage structure driving the nozzle to move precisely, ensuring uniform coverage of the molding surface with anti-stick, avoiding the unevenness of manual spraying, reducing product damage and mold cleaning burden caused by adhesion. The innovative dual-path adjustment design can flexibly control the concentration of anti-stick according to the rubber hardness. Pure anti-stick is used for hard rubber to ensure the anti-stick effect, while diluted anti-stick is used for soft rubber to avoid excessive residue, preventing adhesion without affecting the product's elasticity and pressure resistance, adapting to different material requirements. Weight sensing and alarm mechanisms monitor the raw material balance in real time, reminding for timely replenishment to avoid production interruptions and improve continuous operation efficiency. The uniform film layer formed by atomized spraying further ensures the surface precision of the seal and reduces molding defects, ultimately achieving efficient and high-quality production of pressure-resistant and wear-resistant rubber seals, balancing stability and adaptability.

[0022] like Figure 1As shown in Figure 4, the injection mold for the pressure-resistant and wear-resistant rubber sealing ring includes an injection molding machine frame 1. An L-shaped side plate 6 is fixedly connected to the right end of the injection molding machine frame 1. An electric horizontal push rod 7 is fixedly connected to the vertical end of the L-shaped side plate 6 near the molding template 5. A hollow linkage frame 8 is installed at the output end of the electric horizontal push rod 7. A diluent storage tank 9 and a release agent storage tank 10 are respectively placed on the front and rear sides of the upper end of the hollow linkage frame 8. The lower end of the diluent storage tank 9 is fixedly connected to... An alcohol outlet pipe 13 extends into the hollow linkage frame 8. The lower end of the release agent storage tank 10 is fixedly connected to a release agent outlet pipe 15 extending into the hollow linkage frame 8. Atomizing nozzles 12 are fixedly connected to the front and rear sides of the lower end of the hollow linkage frame 8, respectively. The upper ends of the two atomizing nozzles 12 are fixedly connected to the corresponding alcohol outlet pipe 13 and release agent outlet pipe 15, respectively. An electric valve block 14 is fixedly connected to the upper ends of both sets of alcohol outlet pipes 13 and release agent outlet pipes 15.

[0023] A hydraulic device 4 is fixedly connected to the upper end of the injection molding machine frame 1, and a pressure plate 3 is slidably connected to the upper inner wall of the injection molding machine frame 1.

[0024] The lower inner wall of the injection molding machine frame 1 is fixedly connected to a pressure plate 2, and the liquid outlet end of the atomizing nozzle 12 is intermittently displaced at a uniform speed above the pressure plate 2.

[0025] The pressure plate 2 and the pressure plate 3 are both fixedly connected to a forming template 5 at their close ends, and the output end of the hydraulic device 4 is connected to the pressure plate 3.

[0026] Multiple electrical valve blocks 14 are respectively installed at the liquid outlet of the diluent storage tank 9 and the release agent storage tank 10, and the upper end of the hollow linkage frame 8 is symmetrically fixedly connected with the front and rear sides of the ring-shaped storage groove 11.

[0027] A weight sensor 16 is fixedly connected to the inner wall of the circular storage trough 11, and the diluent storage tank 9 and the release agent storage tank 10 are respectively detachably installed in the corresponding circular storage trough 11.

[0028] An alarm light 17 is fixedly connected to the side end of the circular storage slot 11, and the alarm light 17 and the weight sensor 16 are connected to each other by a wire.

[0029] This is used in pressure-resistant and wear-resistant rubber sealing rings. The injection molding machine frame 1 provides the installation foundation for the entire equipment. The hydraulic unit 4 fixed at its upper end serves as the power source, driving the upper inner wall slidingly connected pressure plate 3 to move up and down. It cooperates with the lower inner wall fixed pressure plate 2 to complete the mold closing and opening actions. After the molding template 5 at the opposite ends of pressure plate 2 and pressure plate 3 closes, it forms a cavity for the injection molding of rubber raw materials. The anti-stick spraying component is fixed to the right end of the injection molding machine frame 1 through L-shaped side plates 6. Its core is a hollow linkage frame 8 driven by an electric horizontal push rod 7. The output end of the electric horizontal push rod 7 drives the hollow linkage frame 8 to move horizontally, so that the atomizing nozzle 12 at the lower end can intermittently move at a uniform speed above pressure plate 2 in coordination with the mold closing and opening actions, ensuring that the spraying range covers the entire surface of the molding template 5. The upper front and rear sides of the hollow linkage frame 8 are respectively placed with a diluent storage tank 9 and a release agent storage tank through a ring-shaped storage groove 11. Tank 10 and the corresponding alcohol outlet pipe 13 and mold release agent outlet pipe 15 deliver liquid to atomizing nozzle 12. The electrical valve block 14 at the upper end of the outlet pipe can control the output ratio of the two liquids: when producing hard rubber sealing rings with a Shore hardness > 80, the electrical valve block 14 closes the diluent storage tank 9 passage, allowing only pure mold release agent to pass through; when producing soft rubber with a Shore hardness < 60, the alcohol passage is opened, and the mixture is diluted at a ratio of 50% to avoid excessive residue of anti-sticking agent affecting the elasticity of the sealing ring. At the same time, the weight sensor 16 on the inner wall of the ring-shaped storage groove 11 monitors the weight of the storage tank in real time. When the alcohol or mold release agent is insufficient, the alarm light 17 connected by the wire lights up to remind replenishment, ensuring that the spraying process is not interrupted. Finally, the mixed anti-sticking agent forms a uniform mist film through the atomizing nozzle 12 to cover the molding template 5, and completes the efficient molding of the rubber sealing ring with the opening and closing of the mold, which avoids adhesion and ensures its pressure resistance and wear resistance.

[0030] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
