Description

Pressing plate guiding device

Technical Field

The utility model relates to a molding machine field, concretely relates to clamp plate guider.

Background

When the molding machine for casting the soil-stained sand is used, firstly, air pressure is utilized to blow the molding sand into a sand box provided with a mold, then, the molding sand is extruded and molded by utilizing the force of hydraulic pressure, air pressure or a motor and the like, then, the mold is taken out, then, the sand mold bodies taken out of the mold are combined together to form a complete molding sand body, and then, the molding sand body is moved to a casting platform or a position for casting.

When the existing molding machine is used for manufacturing a sand mold, the upper sand box and the lower sand box are required to be moved to the designated positions to be aligned with a sand shooting opening, then sand shooting operation is carried out, and after sand shooting, the upper pressing plate and the lower pressing plate are driven to move to compact sand grains. When the upper pressing plate and the lower pressing plate are pressed in parallel, a plurality of air cylinders or oil cylinders are generally used for driving. However, the cost of using multiple cylinders or cylinders is greatly increased, and the failure rate is also increased. How to ensure that the upper pressure plate and the lower pressure plate keep stable during movement is a problem to be solved.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model aims at providing a better clamp plate guider of depth of parallelism.

In order to realize the technical purpose, the utility model discloses a scheme is: a pressure plate guiding device comprises a pressure plate, guide rods, a compaction cylinder and a slide rod, wherein a movable plate is mounted on the slide rod, the compaction cylinder and a plurality of guide rods are mounted on the movable plate, the compaction cylinder is in driving connection with the pressure plate, one end of each guide rod is fixedly connected with the pressure plate, the other end of each guide rod is fixed with a fixed frame, and the parallel degree of the pressure plate can be kept stable during up-and-down movement through the plurality of guide rods which are connected into a whole;

the guide rods are four and are connected into a whole through the fixing frame, and the guide rods can slide up and down on the movable plate.

Preferably, the compaction cylinder is a cylinder.

Preferably, a sliding sleeve is arranged in the movable plate, and the guide rod is connected with the sliding sleeve in a nested mode.

The guide device has the advantages that the guide device can be used for an upper pressing plate and a lower pressing plate, the parallelism of the pressing plates during driving and pressing of the compaction cylinders can be effectively improved, and even if only one compaction cylinder is used for driving, the fault of clamping caused by the inclination of the pressing plates is not easy to occur; the parallel degree of the pressing plate can be kept stable under the condition of saving the compaction cylinder.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a partial structure of the present invention when applied to the upper platen;

fig. 3 is a schematic view of a partial structure of the present invention when used for pressing down the plate.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, a specific embodiment be a clamp plate guider, including clamp plate 1, guide arm 2, compaction jar 3 and slide bar 4, install fly leaf 5 on the slide bar 4, install compaction jar 3 and a plurality of guide arm 2 on the fly leaf 5, the drive is connected with clamp plate 1 on the compaction jar 3, 2 one end of guide arm and clamp plate 1 fixed connection, the 2 other ends of guide arm are fixed with mount 6, and the depth of parallelism when activity about can guarantee clamp plate 1 through many guide arms 2 that fuse into an organic whole keeps stable. The guiding device of this application both can be used for the top board, also can be used for the holding down plate, even only use a cylinder or hydro-cylinder, top board or holding down plate still can keep parallel translation.

In order to ensure the parallelism of the pressing plate, the number of the guide rods 2 is four, the guide rods 2 are connected into a qualified whole through a fixing frame 6, and the guide rods 2 can slide up and down on the movable plate 5.

In order to ensure the compaction force of the pressure plate, the compaction cylinder 3 is an oil cylinder.

In order to ensure that the guide rod slides more smoothly and stably, a sliding sleeve is arranged in the movable plate 5, and the guide rod 2 is connected with the sliding sleeve in a nesting manner.

The guide device can be used for an upper pressing plate and a lower pressing plate, the parallelism of the pressing plates during driving and pressing of the compaction cylinders can be effectively improved, and even if only one compaction cylinder is used for driving, the clamping fault caused by the inclination of the pressing plates is not easy to occur; the parallel degree of the pressing plate can be kept stable under the condition of saving the compaction cylinder.

The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
