Description

Glass mold non-riser casting processing device

Technical Field

The utility model relates to a glass mold processing technology field, concretely relates to glass mold does not have rising head casting processingequipment.

Background

With the improvement of the daily living standard of people in China year by year, the daily glass product industry in China is also developed vigorously; the vigorous demand of daily glass bottle and jar products such as beer bottles, red wine bottles, white wine bottles, beverage bottles, seasoning bottles and the like also drives the development of the glass mold manufacturing industry, and the glass mold is an important component in the production process of daily glass products and is one of the key elements of glass product molding. The daily glass product is internationally regarded as the safest and environment-friendly food and medicine packaging material because the daily glass product has good chemical stability and does not react with the contained materials chemically, and the daily glass product is prepared from glass raw materials which are melted at a high temperature of more than 1500 ℃ and can be repeatedly melted and reused. In recent years, with the continuous improvement of the living standard of residents in China, the demand of daily glass products is also increasing. When the yield of glass products is increased year by year, because the quality requirements of people on the glass products are higher and higher, the forming process and equipment of glass product manufacturing enterprises are more and more advanced, and the production forming speed of the glass products is faster and faster, the higher requirements are provided for the metal material for manufacturing the glass mold

The glass mold is specially used for molding glass products, and the materials are selected from gray iron, vermicular iron and nodular iron. Most glass mold casting devices in the industry at present adopt a riser feeding mode to make up for defects such as shrinkage cavities and shrinkage porosity inside castings, the existing processing device is composed of an upper box body and a lower box body, a casting cavity, a pouring gate, an ingate and a riser are arranged in the upper box body, an iron core for chilling is placed in the lower box body, when the glass mold is processed, the upper box body and the lower box body are combined to pour molten iron, and excessive molten iron flows out from the riser in the processing process due to the existence of the riser, so that a water riser is generated, the molten iron utilization rate in the processing process is low and is generally between 55% and 70%, and the production cost of enterprises is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a glass mold does not have rising head casting processingequipment to too much molten iron can be flowed out by the rising head in the course of working that solves prior art existence, the molten iron low in utilization ratio, problem that manufacturing cost is high.

The utility model provides a technical scheme that its technical problem adopted is:

a riser-free casting processing device for glass molds comprises an upper box body and a lower box body, wherein a sprue cup which is communicated up and down is arranged in the middle of the upper box body, casting cavities are respectively formed in two sides of a sprue seat at the bottom of the sprue cup, chilling iron cores are respectively arranged in the lower box body corresponding to the casting cavities of the upper box body, the sprue seat of the upper box body is connected with a breeding port in the middle of the lower box body, and the breeding port is respectively communicated with a liquid inlet at the end part of the casting cavity through cross runners on two sides.

The utility model discloses during the device uses, the chilling iron core in the lower box is in respectively in the foundry goods die cavity of last box, and raw materials molten iron is by the pouring basin pouring of last box, and the molten iron flows to the foundry goods die cavity respectively through the cross gate by the pouring basin through the mouth of breeding of lower box, and the molten iron receives the chilling effect of chilling iron core and forms glass mold fast in the foundry goods die cavity, and the gas that produces in the casting process rises to the air discharge duct of foundry goods die cavity top. The utility model discloses set up the foundry goods die cavity at last box, shifted the water inlet, avoided foundry goods die cavity contact glass material, prevent the production of pitted skin phenomenon.

The utility model discloses set up two-sided template in upper and lower box, the box compound die about the during operation pours into the molten iron from the runner, guarantees the die cavity and cools off fast through cross gate and water inlet control molten iron flow speed, reaches the feeding effect to remove the rising head, this technology is fallen to 6kg by raw water rising head weight 18kg, and the molten iron utilization ratio has reached more than 90%, has reduced the cost of enterprises.
