Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile model frame forming equipment, especially relates to a automobile model frame die casting forming device. BACKGROUND

[0002] In the field of automobile manufacturing, automobile model frame as an important tool for automobile research and development, design verification and teaching display, its quality and precision play a vital role in the development of related work. Die casting forming process has become one of the commonly used forming methods in automobile model frame manufacturing due to its high production efficiency, good product size precision, excellent surface quality and many other advantages. However, the current device applied to automobile model frame die casting forming still has some problems to be solved in the structure of the mold.

[0003] In the existing die casting forming device, the disassembly and assembly process of the mold is often complex. Usually, a variety of tools are needed, and several tedious steps are needed to complete the disassembly and assembly of the mold. For example, when disassembling the mold, a large number of fastening bolts may need to be loosened first, and then the parts of the mold are carefully separated. This process not only consumes a lot of time and labor, but also is easy to damage the mold due to improper operation. When installing the mold, the position of each part of the mold needs to be adjusted accurately to ensure accurate docking, otherwise it will cause size deviation, misplacement and other quality problems of the die casting product. This complex disassembly and assembly method seriously affects the production efficiency, increases the production cost, and makes it difficult for enterprises to quickly respond to market demand when facing multi-variety and small-batch automobile model frame production demand, reducing the market competitiveness of enterprises.

[0004] The sealing performance of the mold has a decisive influence on the quality of the die casting forming process. In actual production, due to the defects of the mold structure design or the wear after long-term use, the sealing part of the mold is easy to leak. When the molten metal material is injected into the mold cavity under high pressure, if the mold is not tightly sealed, the metal material will leak out of the gap, not only causing material waste and increasing production cost, but also causing the die casting product to have surface defects such as flash and burr, and even affecting the internal quality and size precision of the product. In addition, the leaked metal material may also damage the mold, shorten the service life of the mold, and further increase the production cost of the enterprise.

Lower die-casting mold shell 1 and upper die-casting mold shell 2 are also connected with sealing component, while lower fixed plate 4 upper end surface fixed installation spring two 18, spring two 18 is set on the periphery of inserted vertical rod 6.

[0028] When disassembly and assembly of mould are needed, operator pulls sliding lap plate 14, sliding lap plate 14 slides in rectangular through slot 9, drives limiting inserted rod 15 to disengage from limiting inserted hole 8, at this time, upper die-casting mold shell 2 and lower die-casting mold shell 1 can be easily separated. When installation of mould is needed, upper die-casting mold shell 2 is close to lower die-casting mold shell 1, so that inserted vertical rod 6 passes through inserted hole 7, sliding lap plate 14 is loosened, sliding lap plate 14 is reset under the action of reset component, limiting inserted rod 15 is inserted into limiting inserted hole 8, to realize the quick installation of mould. Spring two 18 provides elastic force when subsequent separation of mould is needed, to make the separation process more easily. This disassembly and assembly structure greatly improves the disassembly and assembly efficiency of mould, reduces production downtime, and ensures the smooth progress of production process.

[0029] Further, the reset assembly is an important part of the disassembly structure, specifically comprising a strip-shaped groove 10 opened in the inner side wall of the rectangular through slot 9, the two end walls of the strip-shaped groove 10 are fixedly connected with a horizontal fixing rod 11, the horizontal fixing rod 11 is peripherally sleeved with a spring 12, and the horizontal fixing rod 11 is peripherally slidably sleeved with a sliding sleeve block 13.

[0030] Wherein, when the sliding cover plate 14 is pulled, the sliding cover plate 14 drives the sliding sleeve block 13 fixedly connected therewith to slide along the horizontal fixing rod 11 in the strip-shaped groove 10, at this time the spring 12 is compressed.
