A die casting machine is a mechanical apparatus for manufacturing metal parts by heating a metal material to a molten state, then injecting into a pre-designed mold, and finally cooling and solidifying to manufacture metal parts having high precision and complex shapes. The injection part of the die casting machine comprises an injection station which is a key position for realizing the injection process and needs to be well determined before the die casting work starts so as to ensure the quality and the forming effect of the parts. In general, the injection part of the die casting machine works at different stations, so the whole injection position is not fixed, and the elevator of the injection station needs to work.

The existing die casting machine is characterized in that one end of the injection part is connected with the sliding block, the other end of the injection part is connected with the charging barrel connected with the die casting die, and the other end of the charging barrel is connected with the die, so that the sliding block moves up and down to drive the injection part, the charging barrel connected with the injection part and the die to move up and down. When the die casting machine performs the work of injecting the die, the sliding block is connected with the injection station, and the position of the sliding block is fixed by moving the sliding block up and down so as to realize the work of lifting the injection station and fixing the injection station. Specifically, when the injection station of the die casting machine needs to be adjusted in a lifting manner, firstly, a lifting cylinder piston rod is required to extend upwards to push a sliding block to move upwards along a track inside a portal frame, then, a sliding block supporting piece of the injection station which does not meet the production requirement is taken out, and then, another sliding block supporting piece which meets the production requirement is installed on a front cover of the lifting cylinder, so that the newly installed sliding block supporting piece supports the sliding block again, and the lifting adjustment work of the injection station is completed.

However, according to the different injection stations, in the prior art, a single slide support is used to support the slide, but the length of the single slide support cannot be controlled, so that the situation that the slide support with a required height is not encountered is unavoidable, and if the injection station needs to be adjusted, a slide support with a suitable height needs to be manufactured again to support the slide to achieve a suitable injection station, which increases the cost. When the die casting is completed, the slide support of the special specification may not be used later, so that the slide support of the special specification is idle, which causes waste and the slide support which is not used often occupies space for storage.

Detailed Description

In order to make the present utility model better understood by those skilled in the art, the technical solutions in the specific embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1, the injection station lifting structure of the die casting machine in this embodiment includes: portal frame 1, guide rail 2, slider 3, lift cylinder 4, lifter 41, cylinder body shell 42, slider support 5.

Specifically, as shown in fig. 1, in this embodiment, a gantry 1 is fixedly connected to a supporting seat E of an injection component a, a pull rod C for fixedly supporting the supporting seat E is further connected to the supporting seat E, a guide rail 2 is disposed in the gantry 1, a slider 3 can move up and down along the guide rail 2, and a lifting cylinder 4 is disposed below the slider 3. The lifting cylinder 4 comprises a movable lifting rod 41 and a fixed cylinder body shell 42, hydraulic oil is injected into the lifting cylinder 4 through an oil port D so as to push the lifting rod 41 to push the sliding block 3 to move upwards along the guide rail 2, when the sliding block 3 moves to a sufficient height to place the sliding block supporting piece 5 on the cylinder body shell 42, the sliding block supporting piece 5 is connected on the cylinder body shell 42 to support the sliding block 3, then the hydraulic oil is stopped being injected into the lifting cylinder 4, and at the moment, the sliding block 3 moves downwards under the action of gravity until being supported by the sliding block supporting piece 5. In short, the position of the slide 3 can be fixed by supporting the slide 3 by the slide support 5 connected to the cylinder case 41, and the position of the injection member a connected to the slide 3 and the cartridge B connected to the injection member a can be fixed. That is, since the injection member a is connected to the slider 3, the slider 3 is connected to the injection station, and thus, fixing the slider 3 can realize a fixed injection station.

Further, when the lifting operation of the injection station is performed, at least two slide block supports are arranged on the slide block support 5, two adjacent slide block supports are connected through a connecting structure, and the heights of the slide block supports 5 are flexibly configured in a manner of connecting or removing a plurality of slide block supports, so that the slide block support 5 conforming to the injection station does not need to be manufactured again to replace the slide block support 5 not conforming to the injection station. It should be noted that, in actual die casting production, the slider support 5 may be formed by connecting the slider supports with the same specification height, or may be formed by connecting the slider supports with different specifications heights. Therefore, when receiving a new die casting operation, the die casting manufacturer does not need to manufacture a new slide support 5 again to support the slide 3, and can realize the new slide support 5 by preparing a plurality of slide supports with the same specification height or preparing a plurality of slide supports with different specification heights for connection, thereby achieving the effects of saving cost and reasonably utilizing the slide supports and saving the containing space for placing the new slide support 5. For example, if the required slider support 5 is 90cm in height, only 9 slider supports of 10cm are required to be connected if only a single slider support is required; if the slider supports are of various specifications, 1 slider support of 10cm and 4 slider supports of 20cm can be connected, and the slider supports of 90cm do not need to be manufactured again.

By detachably connecting the slider supports 51, 52 using a connection structure, the entire work of the elevator of the slider support 5 can be facilitated. It should be noted that, the protrusion or the groove at the end of the slider support needs to be set according to the specific situation of the slider support, for example, when the slider support is a solid or the middle of the slider support is hollow and the end is a solid, the protrusion and the groove are set at the end of the slider support; when the sliding block supporting body is a hollow pipe, the bulge is a circular ring bulge, and the groove is a circular ring groove.
