Embodiment 1

[0023] in as figure 1 In the illustrated embodiment 1, a die-casting mold Green column avoidance device, the die-casting mold 1 includes a core 2 and a slider 4 connected with the core and the sliding direction points to the Green column 3, the Green column and the slider 4. There is an oil cylinder 5 for moving the slider, and the oil cylinder is one, located on the outer side of the connecting line between the Green column and the slider, the central axis of the oil cylinder is parallel to the sliding direction of the slider, and the oil cylinder is located in the Green column as a whole. Outside the projection plane in the direction of the slider, the base 6 of the oil cylinder is fixed with the die-casting mold, and the oil cylinder is provided with an outer frame. The outer frame includes a fixed plate 7 and a fixed rod 8 connected with the movable end of the oil cylinder. One end is fixed on the fixing plate, the other end of the fixing rod is fixed with the connecting p...

Embodiment 2

[0025] in as figure 2In the illustrated embodiment 2, there are two oil cylinders, which are symmetrically arranged on the outside of the connecting line between the Green column and the slider, the central axis of the oil cylinder is parallel to the sliding direction of the slider, and the oil cylinder is located on the Green column as a whole in the direction of the slider. Outside the projection plane of , the connecting plates on the two cylinders are of a homogeneous structure (see Figure 4 Figure 5 ), the middle of the connecting plate is fixedly connected with the outer side of the slider.

[0026] There is a sliding sleeve 12 between the connecting plate and the oil cylinder (see Image 6 ), the outer circumference of one end of the sliding sleeve is provided with a convex ring 13, and the sliding sleeve is fixed on the connecting plate by a pressing plate 14 abutting on the convex ring.

[0027] Example 2 The outer side of the slider is provided with an oil cyli...

Embodiment 3

[0030] in as image 3 In the illustrated embodiment 3, there are two oil cylinders, which are symmetrically arranged on the outside of the connecting line between the Green column and the slider, the angle between the central axes of the two oil cylinders is 90 degrees, and the front end of the oil cylinder is located at the Green column at the In the projection plane in the direction of the slider, the rear end of the oil cylinder is located outside the projection plane of the Green column in the direction of the slider, the connecting plate of the oil cylinder is hinged with a connecting rod 11, and the other end of the connecting rod is hinged with the slider, and the rest are implemented Example 1 or Example 2 are the same.

[0031] The working methods of the die-casting mold Green column avoidance device of Example 2 and Example 3 are as follows: two oil cylinders work alternately, each oil cylinder works 5 to 10 times respectively, and each time the slider is pulled at a...

Abstract

The invention discloses a die casting die tie bar avoidance device and method. A die casting die comprises a core and slide block which is connected with the core and faces towards a tie bar in the sliding direction; an oil cylinder used for moving the slide bock is arranged between the tie bar and the slide block and located on the outer side of the connection line between the tie bar and the slide block; a base of the oil cylinder is fixed to the die casting die; an outer frame is arranged on the oil cylinder and comprises a fixing plate connected with the movable end of the oil cylinder, and fixing rods; one ends of the fixing rods are fixed to the fixing plate, and the other ends of the fixing rods are fixed to a connection plate which slidably sleeves a cylinder barrel of the oil cylinder and is connected with the slide block. Through the die casting die tie bar avoidance device and method, the problem that core pulling demolding of the die casting die cannot be achieved when thecore number of a die casting mold is large in the prior art is effectively solved, and the quite high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, and in particular, to a device and method for avoiding a Green column of a die-casting mold. Background technique [0002] In the prior art flat multi-cylinder core-pulling product mold, due to the large number of cores, there is an interference phenomenon between some cores and the Green column. Since the moving direction of the die slider points to the Green column, in the manufacture of general molds, the cylinder is straight. For the green column, the cylinder collides with the green column of the press before the slide block of the mold is fully opened. Therefore, when the mold parting surface is on the same plane as the product core-pulling evenly distributed, the demoulding cannot be achieved. Post out of the way. The patent document whose publication date is February 1, 2017 and whose publication number is CN205914637U discloses a folding machine avoidance mold mechanism, inclu...
