Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of fuel injection rings for electric motor cooling devices in new energy vehicles, and in particular to a mold for an automotive fuel injection ring. Background Technology

[0002] In the current manufacturing field of fuel injection rings (the sealing rings of fuel injectors) for new energy vehicle motor cooling devices, the mainstream manufacturing methods for fuel injection ring structures are mostly circular flat plate molding structures or circular injection structures. Taking common molds as an example, such as... Figure 1 As shown, its main structure consists of three parts: an upper mold plate, a lower mold plate, and a mold core lifting frame assembly. In the actual production process, the rubber material needs to be processed into a specific shape in the preceding process and then placed on the upper and lower surfaces of the mold core. Next, pressure and temperature are applied by the vulcanizing equipment, and after a certain period of vulcanization reaction, when the mold is opened, the operation procedure is to first open the upper mold plate, then lift the mold core lifting frame assembly, and with the assistance of an air gun, the product can be removed, thus completing the entire vulcanization production process. However, this traditional mold structure has exposed many obvious defects: (1) Low material loading efficiency: The manual placement of pre-processed rubber materials is an extremely cumbersome and time-consuming process, which seriously restricts the improvement of overall production efficiency and cannot meet the growing market demand for production capacity; (2) High requirements for human skills: Since the accuracy of the placement of rubber materials has a decisive impact on the quality of the final product, operators must have superb operating skills and rich practical experience, which greatly increases the investment in human resources and the difficulty of personnel training; (3) Low production capacity: The above factors of slow material loading speed and high requirements for operator skills are superimposed, resulting in a low overall production efficiency. In the context of the rapid development of the new energy vehicle industry and the sharp increase in the demand for oil injection rings in motor cooling devices, the problem of insufficient production capacity has become increasingly prominent and has become a key bottleneck restricting the development of the industry. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an automotive fuel injection ring mold.

[0004] This utility model discloses an automotive fuel injection ring mold, which is installed on an injection vulcanizing press. It includes an upper mold plate and a lower mold plate, and multiple fuel injection ring mold cavities are provided between the upper mold plate and the lower mold plate. The mold cavities are elliptical in shape. The side of the upper mold plate is provided with a heating plate with heating pipes, a heat insulation plate, and a runner plate in sequence. The runner plate is provided with a cold runner system for storing rubber material. The cold runner system is connected to multiple injection towers, each corresponding to one of the mold cavities. The injection towers penetrate the heat insulation plate, the heating plate, and the upper mold plate, and are used to inject the rubber material into the runner of the lower mold plate and then into the mold cavity.

[0005] Preferably, the accuracy of the mold cavity is ±0.02mm, and the shrinkage rate is set to 1.023.

[0006] Preferably, the mold cavity is mirror polished with a roughness Ra≤0.8μm.

[0007] Preferably, the heat insulation board is made of ceramic fiber composite material with a thickness of 10-15mm.

[0008] Preferably, the temperature setting of the cold runner system is stable at 60±5℃.

[0009] Preferably, the mold cavity has eight sections, and the cold runner system is connected to each of the injection towers through eight sections of runners.

[0010] In summary, this utility model has the following beneficial effects: (1) Improved production efficiency: The elliptical mold cavity realizes the simultaneous operation of vulcanization and demolding. The injection structure of the cold runner system and injection tower greatly saves the time of manual application of adhesive, thereby improving production efficiency and fully meeting the market's rapidly increasing demand for automotive fuel injection rings; (2) Significantly reduced labor costs: The mold structure reduces manual operation links and significantly reduces the dependence on operator skills. This not only reduces labor cost input but also reduces the difficulty and burden of personnel training; (3) Saved manufacturing costs: The cold runner system structure improves material utilization. At the same time, the improvement in production efficiency also makes equipment costs and labor costs more effectively distributed, thereby reducing the overall manufacturing cost in all aspects.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 2-4 As shown in the figure, the present embodiment proposes an automotive fuel injection ring mold, which is installed on an injection vulcanizing press (250T). It includes an upper mold plate 1 and a lower mold plate 2. Multiple fuel injection ring mold cavities 3 are provided between the upper mold plate 1 and the lower mold plate 2. The mold cavity 3 is designed as an elliptical structure. The side of the upper mold plate 1 is provided with a heating plate 4 with heating pipes, a heat insulation plate 5 and a runner plate 6 in sequence. The runner plate 6 is provided with a cold runner system for storing rubber material. The cold runner system is connected to multiple injection towers (not shown in the figure) that correspond one-to-one with each mold cavity 3. The injection towers pass through the heat insulation plate 5, the heating plate 4 and the upper mold plate 1, and are used to inject the rubber material into the runner of the lower mold plate 2 and then into the mold cavity 3.

[0020] Specifically, in order to meet the mold production requirements and maintain stable quality, the upper mold plate 1 and the lower mold plate 2 can be made of high-strength, high-wear-resistant high-quality mold steel, the heating plate 4 is made of metal material with excellent thermal conductivity, and the heat insulation plate 5 is made of ceramic fiber material with excellent heat insulation performance and a thickness of 10-15mm.

[0021] Thus, production efficiency is improved: the elliptical mold cavity 3 enables simultaneous vulcanization and demolding, and the cold runner system and injection tower injection structure greatly save time for manual application of adhesive, thereby improving production efficiency and fully meeting the rapidly increasing market demand for automotive fuel injection rings; labor costs are significantly reduced: the mold structure reduces manual operation steps, significantly reducing reliance on operator skills, which not only reduces labor cost input but also alleviates the difficulty and burden of personnel training; manufacturing costs are saved: the cold runner system structure improves material utilization, and the increased production efficiency also allows for more effective allocation of equipment and labor costs, thereby comprehensively reducing overall manufacturing costs.

[0022] Furthermore, during the processing, the machining accuracy is strictly controlled to ensure that the accuracy of mold cavity 3 is ±0.02mm, the shrinkage rate is set to 1.023, and mold cavity 3 is mirror polished with a roughness Ra≤0.8μm. This ensures that the manufactured oil injection ring meets extremely high standards in terms of dimensional accuracy and surface quality, fully meeting the extremely stringent quality requirements of new energy vehicle motor cooling devices for oil injection rings.

[0023] Furthermore, the temperature setting of the cold runner system is stabilized at 60±5℃, ensuring the fluidity of the adhesive. This avoids the troublesome problem of adhesive curing and generating flash within the runner in traditional hot runner systems, greatly improving material utilization and thus significantly saving manufacturing costs.

[0024] The heating plate 4 provides stable and suitable temperature conditions for the vulcanization process of the mold, ensuring the stability of product quality. The heat insulation plate 5 precisely separates the heating plate 4 and the runner plate 6. Its heat insulation performance effectively prevents temperature from being conducted from the heating plate 4 to the cold runner system of the runner plate 6, thereby ensuring that the cold runner system is always maintained in a relatively low temperature range. This ensures that the cold runner system can operate normally and stably, and prevents the rubber compound from undergoing a premature vulcanization reaction in the cold runner.

[0025] In this embodiment, the mold cavity 3 is provided with eight parts, and the cold runner system is connected to each injection tower through the eight parts of the runner system. In this way, the tedious operation of manually applying the adhesive is eliminated, which greatly improves the feeding speed and further improves the production efficiency.

[0026] In summary, in this embodiment, the mold sequentially assembles the upper and lower mold plates 2 and the upper mold plate 1. Then, the injection structure, consisting of the cold runner system and the injection tower, is activated. The rubber compound is directly injected into the runner of the lower mold plate 2 via the injection tower, and then flows into the mold cavity 3. Simultaneously, the heating plate 4 starts working to provide the necessary stable temperature for the vulcanization process. During vulcanization, the equipment's control system monitors key parameters such as temperature and pressure in real time and accurately to ensure a stable and orderly vulcanization process. At the same time, workers can simultaneously remove the vulcanized product from the mold core. This cycle is repeated to achieve efficient mass production of automotive fuel injection rings.
