Embodiment Construction

[0023] With reference to Fig. 1, a kind of double-station horizontal parting injection molding machine that is used for producing sand mold, comprises: base 17, is provided with column 16 on base 17 and one end of column 16 is connected with base 17, on column 16 Two crossbeams 151 and 152 are arranged on the other end of the cylinder, and one of the crossbeams 151 is provided with an upper sand mold compacting and unboxing oil cylinder 14 and an upper box double-side sand shooting mechanism 12, and the upper sandbox is connected to the crossbeam 151. 2. There are sand inlets 21, 22 on the front and rear sides of the upper sand box 2, respectively, and the sand inlets 21, 22 are respectively connected to the two sand outlets of the double-side sand shooting mechanism 12 of the upper box (refer to Fig. 7) to form a closed sand shooting channel on both sides. The upper sand mold compaction and box removal oil cylinder 14 includes a cylinder body and a piston rod. Pressing plate ...

Abstract

The invention discloses a double station horizontal parting slip flask shoot-squeeze molding machine for producing sand mould, including base (17), a pillar (16) is provided on the base (17), two crossbeams (151, 152) are provided on the other end of the pillar (16), on one of which are provided with an upper sand mould compacting snapflask oil cylinder (14) and an upper box both sides shoot sand mechanism (12), an upper sand box (2) is connected on the crossbeam (151), the invention is based on horizontal parting slip flask shoot-squeeze molding technique, making the upper and lower molding divided on two stations of one machine, the upper and lower sand boxes respectively shoot sand on both sides for implementing both-way compaction and ensuring sand stream to max casting back area, which can ensure satisfied solidity for single mould of more than 200 mm, and with condition of producing high mould.

Description

technical field [0001] The invention relates to a molding machine, in particular to a double-station horizontal split-type out-of-box injection molding machine. Background technique [0002] The horizontal parting out-of-box injection molding line is generally suitable for manufacturing sand molds with a block height of less than 200mm. For larger castings such as engine cylinders and brake drums, the height of a single block is required to be more than 200mm. Because the above-mentioned existing molding line uses sand-shooting and sand-filling and medium-pressure compaction technology, the pressure applied to the mold blocks above 200mm cannot reach the other side of the pressure, resulting in insufficient compaction so that its application is limited. Therefore, the current technique for producing such larger castings uses box molding. The upper and lower boxes are respectively manufactured on two or multi-station turntable molding machines. The sand compaction process ...
