Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile production, in particular to a casting island for intelligent manufacturing of automobile engine accessories. BACKGROUND

[0002] The casting island is an advanced manufacturing system integrating automation, digitization and intelligence, which can be applied to efficiently and precisely produce engine core components. The core generally includes an ultra-large die casting island, core making and mold equipment, cleaning and post-processing equipment, pouring and conveying equipment, and auxiliary and environmental protection equipment. The ultra-large die casting island generally adopts a 6000T-16000T ultra-large die casting island (such as a new answer 16000T die casting island), which can form engine cylinder blocks, chassis and other complex structural parts at one time, reducing the welding link and improving the overall strength and production efficiency.

[0003] Among them, the best working temperature range of mold demolding is generally controlled in the range of 180℃-280℃ (aluminum alloy die casting); the ideal surface temperature is 150-300℃, which can avoid defects such as cold separation, flow lines and mold sticking; the critical temperature limit is that the minimum demolding temperature is ≥130℃, and below this temperature, it is easy to cause under-casting, cracking and cold separation; the highest safe temperature is ≤300℃, and exceeding this temperature is easy to cause surface bubbles, shrinkage, mold sticking and mold thermal fatigue.

[0004] The existing die casting machine demolding, cleaning and spraying process has significant defects: when using compressed air cleaning, the high-speed airflow in contact with the high-temperature mold will cause rapid cooling of the mold surface due to large temperature difference, causing thermal stress concentration and aggravating the risk of mold fatigue cracks. At the same time, the heat loss of the open space accelerates the overall temperature drop of the mold, increasing energy consumption and prolonging the production cycle; during the demolding agent spraying stage, the low-temperature demolding agent in contact with the high-temperature mold is easy to produce the Leidenfrost phenomenon, and the liquid droplets form a vapor layer on the high-temperature surface and cannot be wetted, resulting in uneven film formation and poor adhesion of the demolding agent. In order to maintain the demolding effect, it is necessary to increase the spraying frequency and dosage, which not only causes waste of the demolding agent, but also may cause surface porosity, cold separation and other defects of the castings due to excessive residue. In addition, temperature fluctuations of the mold will also affect the solidification process of the castings, resulting in uneven internal organization and reduced dimensional accuracy. Frequent temperature changes will also damage the oxide layer on the surface of the mold, accelerate mold corrosion and carbon deposition problems, and demolding agents left for a long time are prone to precipitation. The superposition of these problems not only reduces production efficiency and product quality, but also increases mold maintenance costs and environmental pollution risks, such as waste liquid treatment pressure caused by excessive use of demolding agents.

[0005] Therefore, the present application provides a casting island for intelligent manufacturing of automobile engine accessories, which can heat and keep the demolding agent and compressed air, avoid static precipitation of the demolding agent, and has low energy consumption. SUMMARY

DETAILED DESCRIPTION

[0044] In order to make the technical means, technical features, purposes and effects of the present application easy to understand, the technical features of the prior art part are first clarified, wherein the integrated forming production of automobile chassis, large vehicle body structure and the like mainly relies on die casting process, and the super large die casting island (6000T-16000T level) integrated with intelligent and automatic technology is the first choice for current production and manufacturing, and the working process is simplified as follows:

[0045] Firstly, the mold is pretreated by spraying release agent, and it is necessary to note that the electric heating mold temperature machine can accurately control the temperature (±1℃), the mold surface is sprayed with graphite-based release paste to prevent deep cavity castings from sticking (especially suitable for complex structures such as automobile chassis).

[0046] Secondly, the cupola (15-20 tons / hour) is initially melted and the medium frequency induction furnace is refined, the aluminum liquid temperature is stabilized at 680-720℃ (low pressure casting) or 1380-1420℃ (cast iron), the direct reading spectrometer is used for real-time monitoring of the composition, and then the AGV or mechanical arm is used for automatic transfer, and the molten metal is injected into the injection chamber to avoid temperature fluctuation.

[0047] Finally, in the high-pressure die casting molding filling stage, the injection punch pushes the molten metal at a flow rate of ≥2kg / s, with a filling pressure of 0.02-0.06MPa (aluminum alloy). Equipment with a capacity of 6000T or more can achieve filling in ≤60 seconds. Pressurization and compaction are achieved through secondary pressurization by a multi-contact high-pressure system (pressure 100-175MPa) to eliminate shrinkage porosity and ensure the dense structure of large thin-walled parts (such as battery trays). This process is generally completed in about 10 seconds. It is necessary to use a combination of embedded heating wires and water cooling channels in the mold to reduce deformation through gradient temperature control, or to use a double demolding technology for cooling, i.e., the mechanism drives the inner and outer molds to separate synchronously to solve the problem of deep cavity parts sticking to the mold.

[0048] The present invention will be further described below with reference to specific embodiments.

[0049] Example 1: As Figures 1-19 As shown, the casting island for intelligent manufacturing of automotive engine parts according to the present invention includes a die-casting machine 1 and a mold assembly 2 fixed inside it.

A heat preservation section 8 is connected to the top of the die-casting machine 1. A spraying section 7 is provided at the bottom of the heat preservation section 8. An air storage tank 9 and a material tank 10 are provided at the top of the spraying section 7. A mixing section 11 is driven to one side of the side partitions 3. The heat preservation section 8 includes a threaded pipe 86 fixed inside the air storage tank 9 and an oil tank 85 fixed outside the material tank 10. It heats and preserves the compressed air and release agent by guiding the coolant cooling the mold assembly 2 to flow spirally inside the threaded pipe 86 and the oil tank 85. During the process of sealing the mold assembly 2 with the side partitions 3, the mixing section 11 utilizes an anti-settling plate rotatably connected inside the material tank 10. 114 The release agent is turbulent to prevent sedimentation. The mold assembly 2 includes a moving side module 22 and a fixed side module 21. The moving side module 22 is fixed to the moving mold base of the die casting machine 1, and the fixed side module 21 is fixed to the fixed mold base of the die casting machine 1. The heat preservation part 8 also includes a base plate 82 and a top cover 81.
