Problems solved by technology

The disadvantage of this kind of moving mechanism is that it is necessary to install an additional power mechanism (hydraulic core puller) on the die-casting machine, which consumes energy and increases the space occupied by the die-casting machine, which cannot be applied to some factories with small workshop space.

Embodiment Construction

[0012] The present invention will be further described in detail below through specific implementations:

[0013] The reference signs in the drawings of the specification include: lever 1, positioning pin 2, driven rack 3, transmission gear 4, movable core 5, driving rack 6, adjusting screw 7, static mold 8, and movable mold 9.

[0014] The lever 1-type movable core moving mechanism is basically as attached figure 1 Shown:

[0015] The lever type movable core moving mechanism is arranged on a die casting machine, which includes a movable mold 9 and a static mold 8. The grooves on the movable mold 9 and the protrusions on the static mold 8 are aligned to form a casting cavity . An active rack 6 pointing to the movable mold 9 is fixed on the fixed mold. An active rack groove for accommodating the active rack 6 is opened on the side of the movable mold 9 opposite to the active rack 6. When the movable mold 9 moves, the active rack 6 6 can move in the active rack groove.

Abstract

The invention belongs to the technical field of die casting, and discloses a lever-type movable core moving mechanism. The lever-type movable core moving mechanism is arranged a moving die and a static die of a die casting machine, and comprises a movable core and a driving rack fixedly connected on the static die, wherein a transmission gear meshed with the driving rack is pivotally connected on the moving die; the transmission gear is meshed with a driven rack arranged on the moving die; the inner end of the driven rack is fixedly connected with the movable core; and a compassion mechanism is arranged at the outer end of the driven rack. In the scheme, the driven rack, the driving rack and the transmission gear are mounted on dies (the moving die and the static die) of the die casting machine, so that the mounting space is saved, and a dynamical structure is not needed to be additionally arranged.

Description

Technical field [0001] The invention belongs to the technical field of die casting. Background technique [0002] In the die-casting production process, when the die-casting part has grooves or holes in the direction perpendicular to the opening direction, a movable core must be set on the die-casting mold. The movable core is inserted into the casting cavity when the mold is closed. When the mold is opened, the movable core exits the casting cavity. If the grooves and holes are small and shallow, the casting will not hold the core tightly during the condensation process, and the core pulling action can be completed by using the mechanical core pulling structure set on the mold when the mold is opened. [0003] The existing movable core moving mechanism is composed of a hydraulic core puller, a core puller seat and a coupling. The piston rod of the hydraulic core puller is fixedly connected to the movable core built in the casting cavity through the coupling. The piston rod of th...
