Detailed Description
The invention provides a mechanical inclined drawing position structure.
Referring to fig. 1 to 6, fig. 1 is an overall front structure diagram of an embodiment of the present invention, fig. 2 is a front cross-sectional structure diagram of an embodiment of the present invention, fig. 3 is an assembly structure diagram of a first traveling seat and a second traveling seat in an embodiment of the present invention, fig. 4 is an outer structure diagram of one of the guide plates in an embodiment of the present invention, fig. 5 is an inner structure diagram of one of the guide plates in an embodiment of the present invention, and fig. 6 is a structure diagram of a shovel machine in an embodiment of the present invention.
As shown in fig. 1-2, in the embodiment of the present invention, the mechanical slant extraction bit structure includes: the die comprises two guide plates 100 which are parallel and fixed on the fixed die side of the die, a row seat assembly 200 fixed on the movable die side of the die, and a row seat insert 300 fixed on the row seat assembly 200. The fixed mold side here means: a fixed die plate, a fixed die core or a combination of two or more of the fixed die plate, the fixed die plate and the fixed die core. The movable mould side is as follows: the movable die base plate or the movable die core or a combination of two or more of the movable die base plate or the movable die core.
The row seat assembly 200 includes: a first travel base 210 and a second travel base 220.
The first traveling seat 210 is fixed to the movable mold side of the mold and moves in a vertical mold opening or closing direction with the movable mold side of the mold. For the movable mould side of the mould to move more stably and smoothly along with the mould opening and closing, so that the first displacement seat 210 on the movable mould side moves more stably and smoothly along with the mould opening and closing, the outer side walls of the two guide plates 100 are provided with first guide grooves 110 along the mould opening or closing direction of the mould, and the first guide blocks 111 fixedly connected with the movable mould side of the mould are arranged in the first guide grooves 110 in a sliding manner.
As shown in fig. 2 to 5, the top end surface of the first slide seat 210 is provided with an inclined slide rail 211, the bottom of the second slide seat 220 is provided with a limiting slide bar 221, and the limiting slide bar 221 is slidably disposed in the slide rail 211. The inner side walls of the two guide plates 100 are both provided with inclined sliding grooves 120, the second slide seat 220 is provided with limit pins 222 corresponding to the sliding grooves 120 one by one, and the limit pins 222 slide in the corresponding sliding grooves 120. The slide insert 300 is fixed to the second slide mount 220 by a T-block.
The chute 120 forms a certain angle with the mold opening or closing direction of the mold, and the slide rail 211 forms a certain angle with the chute 120. When the first slide seat 210 is opened or closed along with the mold, the second slide seat 220 can move along the slide groove 120 and the slide rail 211 under the limiting action of the limiting slide bar 221 and the limiting pin 222, so that the slide insert 300 fixed on the second slide seat 220 can realize the oblique core-pulling and mold-closing movement.
Since only a part of the space between the second travel seat 220 and the first travel seat 210 is matched with the slide rail 211 through the limiting slide bar 221, the movement stability of the second travel seat 220 is reduced. In order to make the movement of the second slide seat 220 more stable and smooth, in this embodiment, the second guide blocks 223 are disposed on two sidewalls of the second slide seat 220 not engaged with the slide rail 211, a second guide groove (not shown) parallel to the slide rail 211 is disposed in the movable mold side of the mold, and the second guide blocks 223 slide in the second guide groove.
Because the mold opening force and the mold closing force of the mold are large, in order to increase the strength and the stability of the direct connection of the first displacement seat 210 and the movable mold side of the mold and reduce the deformation of the connection part of the first displacement seat 210 and the movable mold side of the mold under the mold opening force and the mold closing force, the movable mold side of the mold is also provided with a fixed block 230 for supporting the first displacement seat 210. The fixing block 230 is disposed below the first traveling block 210 and directly connected to the moving mold side of the mold.
According to the technical scheme, the slide insert 300 is driven to perform inclined drawing and mold closing actions by utilizing the mold opening or mold closing force of the mold, so that the mold can run more stably and smoothly. And, an elastic plate or an oil cylinder is omitted, so that the structure and the size of the mold are greatly simplified, the mold can be suitable for smaller injection molding machines, and the use cost of the mold is greatly reduced.
Preferably, in this embodiment, in order to prevent the second slide seat 220 and the first slide seat 210 from being easily deformed and damaged by the stopper pin 222 and the stopper slide 221 under the action of the injection pressure during the mold clamping and injection, and further causing the second slide seat 220 and the first slide seat 210 to retreat, as shown in fig. 6, a shovel 400 is further disposed between the two guide plates 100, and the shovel 400 is fixed on the fixed mold side of the mold and disposed above the first slide seat 210. The bottom of the shovel machine 400 is provided with a V-shaped stop 410, and the top end surface of the first travel seat 210 is provided with a V-shaped groove. When the first slide seat 210 moves along the mold closing direction of the mold until the mold is completely closed, the V-shaped stopper 410 is inserted into the V-shaped groove, and the second slide seat 220 abuts against the V-shaped stopper 410.
Through the rigid matching of the second travel seat 220 and the V-shaped stop block 410 of the shovel machine 400, the second travel seat 220 and the first travel seat 210 can be prevented from retreating under the action of injection molding pressure, and the defect that an oil cylinder or an elastic plate cannot prevent the travel seat from retreating under the action of injection molding pressure is overcome.
In this embodiment, in order to reduce the wear generated by the friction fit between the first traveling seat 210 and the second traveling seat 220, the first traveling seat 210 and the shovel 400, and the second traveling seat 220 and the shovel 400, the matching surfaces of the second traveling seat 220 and the first traveling seat 210 and the matching surfaces of the shovel 400 and the first traveling seat 210 are provided with the wear-resistant blocks 500.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
