SU1526899A1 - Die-casting mould for reinforced casttings - Google Patents

Abstract

The invention relates to foundry, in particular to injection molding of reinforced castings. The purpose of the invention is to improve the performance of the mold. When the mold is closed and opened, the armature 4 from the accumulator 5 enters the channel 12, from which, under the action of its own weight, enters the through groove B of the ejector 11. This occurs at the moment when the ejector 11, rigidly fixed in the plates 3, moves to the initial position. The mold closes and the melt is pressed into the working cavity. After it hardens when the mold of the plate 3 is opened, the ejector 11, the reinforcement 4 and the casting are moved to the ejection stroke. As a result, the reinforcement 4 from the through groove B falls into the ejector cavity 11, being coaxial with the rod 9. When the plates 3 retract to their initial position, the casting is separated from the ejector 11 and the through groove B is installed against the channel 12. As a result, the reinforcement 4 from channel 12 enters the through groove of B. 5 Il.

Noah groove 13 ejector 1 1. This occurs at the moment when the ejector 11, rigidly secured in the plates 3, is moved to its original position. The mold closes and the melt is pressed into the working cavity. After it hardens when the mold of the plate 3 is opened, the ejector 11, the reinforcement 4 and the casting are moved to the ejection stroke

As a result, the reinforcement 4 from the through groove B falls into the ejector cavity 11, being coaxial with the rod 9. When the plates 3 retract to their initial position, the casting is taken off from the ejector 11 and the through groove B is installed against channel 12. As a result, the reinforcement 4 from Karfk- la 12 enters the through groove of B. 5 ill.

The invention relates to foundry, in particular to injection molding of reinforced castings.

The aim of the invention is to improve the performance of the mold.

FIG. 1 shows the proposed mold, a view of the movable half-form; in fig. 2 shows section A-A in FIG. 1 (working position of the form); in fig. 3 - a mold at the time of the start of ejection of the casting; on 4 mg. 4 - the same, at the moment of ejection and insertion of the reinforcement; figure 5 is the same, at the time of the valve in the working cavity and the removal of the casting from the rod.

The mold consists of a movable 1 and a fixed 2 half-molds, ejector plates 3, a device for feeding fittings 4 into the workbench, a hollow, including a storage device 5, a backing plate 7 fixed on the protrusions 6, a metal rod 9,

mounted in the base plate 10 and mounted in the hole of a tubular ejector 11 having a through groove B in the wall, which is connected to the vertical channel 12 of the accumulator 5. The stationary floor form 2 is provided with a rolling pin 13 interacting with the agitator 8.

The mold works as follows.

When the press-form is closed and opened, the rolling pin 13 interacts with the agitator 8, while the armature 4 from the accumulator 5 enters the channel 12. From the channel 12, the armature 4 under its own weight falls into the through groove B of the ejector 11. This occurs in the moment when the ejector 11, rigidly fixed in the plates 3, which are mutually

act on the hydraulic cylinder of the casting machine (not shown), moves to its original position. The mold is closed (Fig. 2) and the molten metal is pressed into the working cavity. After the necessary holding time for solidifying the casting 14, the mold is opened (Fig. 3). The pusher plates 3, when interacting with the hydraulic cylinder of the casting machine, move the pusher 11, the valve 4, which is in the through groove B, the casting 14, to the ejector stroke, providing the gap B. As a result, the valve 4 from the through groove B falls into the ejector cavity 11, mounted coaxially with a metal rod 9 (Fig. 4). When the plates 3 are retracted to their initial position, the casting is separated from the ejector 11 and the installation of the through groove B against channel 12. As a result, the armature 4 from channel 12 enters through the groove B (Fig. 5). The mold is prepared for the next cycle.

The invention allows, in a single stroke of the pushers, to ensure the installation of the reinforcement into the working cavity and the extraction of the casting, which increases the productivity of the mold.
