Description

Metal type low-pressure casting die for oil pan of diesel engine

Technical Field

The utility model relates to a casting technical field, especially a diesel engine oil drain pan metal mold low pressure casting mould.

Background

In recent years, with the continuous improvement of technical thresholds of automobile industry in China, the road running vehicles are subjected to changes of transportation environment conditions such as weight-based charging and continuous rising of oil prices, and development of 'efficient, energy-saving, environment-friendly and safe' series of light-weight road vehicles is urgent. In particular, heavy cards called "cutos" are the subject of major "care" in each department. The light weight heavy truck becomes an industry trend, and is indistinguishable from the national deepened low-carbon environment-friendly industrialization in recent years, and particularly under the mapping of the new energy technology wind cloud surge of passenger vehicles, the development of the light weight heavy truck has practical significance for road toll collection, raw material loss and environment-friendly emission. The weight of the engine is reduced by changing the prior iron casting into the aluminum casting, and a good result is obtained.

The utility model discloses a realize like this, it includes that the ejector plate is spacing, ejector pin clamp plate, guide pin bushing, ejector plate, ejector pin, release link, go up mould link, guide pillar, side are loosed core, the side is loosed core spacing, is gone up the mould, is gone up mould locating pin, psammitolite, die block and sprue bush, characterized by: the die block is installed on low casting equipment, goes up the mould and installs on low casting equipment through last mould link, and die block, last mould, psammitolite and side are loosed core and are closed back formation die cavity, and the side is loosed core and insert in the mould, and the runner cover sets up the lower extreme at the die block, last mould including the kicking plate spacing, go up the mould link, the guide pillar, the side is loosed core spacing and is gone up the mould locating pin, go up the mould link and install the upper end at last mould, the guide pillar is installed on last mould link, the side is loosed core spacing and is installed in the side of last mould, go up the mould locating. The ejector plate is installed on the ejector rod pressing plate in a limiting mode, and the guide sleeve, the ejector rod and the reset rod are installed on the ejector plate.

The utility model has the advantages that: the diesel engine oil sump is produced by low-casting equipment, particularly for small and medium castings which are large in batch and have structures meeting feeding conditions, the low-casting equipment is used for production, the production efficiency is higher, the casting quality is high, the surface is smooth and clean, and the requirements of large-batch products can be met. In addition, low-casting equipment is used for production, gas is discharged along with the pouring pressurization process, the gas trapping tendency is reduced, and the structure is compact.

Drawings

The invention is further described below with reference to the accompanying drawings:

FIG. 1 is a schematic structural diagram of a metal mold low-pressure casting die for a diesel engine oil pan.

Detailed Description

As shown in fig. 1, the metal mold low-pressure casting die for the oil pan of the diesel engine comprises an ejector plate limit 1, an ejector rod pressing plate 2, a guide sleeve 3, an ejector plate 4, an ejector rod 5, a reset rod 6, an upper die connecting frame 7, a guide pillar 8, a side core pulling 9, a side core pulling limit 10, an upper die 11, an upper die positioning pin 12, a casting 13, a sand core 14, a bottom die 15 and a sprue bush 16, wherein the bottom die 15 is installed on low-casting equipment, the upper die 11 is installed on the low-casting equipment through the upper die connecting frame 7, the bottom die 15, the upper die 11, the sand core 14 and the side core pulling 9 form a cavity after being closed, the side core pulling 9 is inserted into the upper die 11, the sprue bush 16 is arranged at the lower end of the bottom die 15, the upper die 11 comprises the ejector plate limit 1, the upper die connecting frame 7, the guide pillar 8, the side core pulling 9, the side core pulling, the side core pulling device comprises a side core pulling 9 and a side core pulling limiting 10 which are arranged on the side surface of an upper die 11, an upper die positioning pin 12 is arranged at the lower end of the upper die 11, and the ejector plate 4 comprises an ejector plate limiting 1, an ejector rod pressing plate 2, a guide sleeve 3, an ejector rod 5 and a reset rod 6. The ejector plate is limited 1 and is arranged on the ejector rod pressing plate 2, and the guide sleeve 3, the ejector rod 5 and the reset rod 6 are arranged on the ejector plate 4.

The working principle of the method is that before mold closing, a mold is preheated and coated with a material, during mold closing, a sand core 14 is placed into a bottom mold 15, the bottom mold 15 and an upper mold 11 are closed by low-pressure casting equipment, positioning is carried out by upper mold positioning 12 in the process so as to ensure accurate mold closing of the mold, finally a side core pulling 9 is inserted into the upper mold 10, the side core pulling limiting 10 is closed, low-pressure casting is carried out after mold closing, and aluminum liquid enters a cavity; when the mold is opened, the side core pulling limit 10 is firstly opened, the side core pulling 9 is pulled out, the upper mold connecting frame 7 is pulled by using a low-pressure casting machine to separate the upper mold 10 from the bottom mold 15, and then the low-pressure casting equipment acts on the ejector rod 5 through the ejector rod pressing plate 2, the ejector plate 4 and the guide pillar 8 to eject and demold the casting 13, so that the casting 13 is taken out. When the mold is closed again, the ejector rod pressing plate 2, the ejector plate 4, the ejector rod 5 and the ejector rod 1 reset when contacting with the bottom mold through the reset rod 6.
