Problems solved by technology

[0003] The present invention solves the problem that in the prior art, when the number of die-casting mold cores is large, interference between part of the cores and the Green column is likely to occur, and the oil cylinder is likely to collide with the Green column of the press, resulting in that the core-pulling and demoulding of the mold cannot be realized. , providing a die-casting mold Green column avoidance device and method capable of avoiding the collision between the oil cylinder and the Green column

Embodiment 1

[0023] in such as figure 1 In the shown embodiment 1, a die-casting mold Green column avoidance device, the die-casting mold 1 includes a core 2 and a slider 4 connected to the core and whose sliding direction points to the Green column 3, the Green column and the slider There is an oil cylinder 5 for moving the slide block between them. The oil cylinder 5 is one and is located on the outside of the line between the Green column and the slide block. The central axis of the oil cylinder is parallel to the sliding direction of the slide block. Outside the projection plane on the slide block direction, the base 6 of the oil cylinder is fixed with the die-casting mold, and an outer frame is provided on the oil cylinder, and 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 fixed plate, the other end of the fixed rod is fixed with the connecting plate 10, one end of the connecting plate is slidably...

Embodiment 2

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

[0026] A sliding sleeve 12 is provided 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 protruding ring 13, and the sliding sleeve is fixed on the connecting plate through a pressing plate 14 abutting on the protruding ring.

[0027] Embodiment 2 The outer surface of the slider is provided with an oil cylinder stroke limiter 15 pointing to the Green column, and the end o...

Embodiment 3

[0030] in such as image 3 In the shown embodiment 3, there are two oil cylinders, which are arranged symmetrically on the outside of the line between the Green column and the slider. The angle between the central axes of the two oil cylinders is 90 degrees. 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, and a connecting rod 11 is hinged on the connecting plate of the oil cylinder, and the other end of the connecting rod is hinged with the slider, and the rest and the implementation Example 1 or Example 2 are the same.

[0031] The working method of the Green column avoidance device of the die-casting mold in embodiment 2 and embodiment 3 is as follows: two oil cylinders work alternately, each oil cylinder works 5 to 10 times respectively, each time the slider is pulled at small intervals at equal intervals, when the slider moves When the amoun...

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, in particular to a Green column avoidance device and method for a die-casting mold. Background technique [0002] In the conventional planar multi-cylinder core-pulling product mold, due to the large number of cores, there is interference between some cores and the Green column. Since the moving direction of the mold slider points to the Green column, in general-purpose mold manufacturing, the cylinders directly For the Green column, before the mold slider is fully opened, the oil cylinder collides with the Green column of the press, so the demoulding cannot be achieved when the mold parting surface is on the same plane as the product cores are evenly distributed, and the Green column that hinders the movement of the cylinder must be removed Pillar out of the way. The patent document with the publication date of February 1, 2017 and the publication number CN205914637U discloses a foldi...
