Abstract
The invention provides a rear die inclined elastic structure of a die for machining an inverted L-shaped workpiece. The rear die inclined elastic structure is reliable, convenient and quick for opening and closing the die and comprises an upper die, a lower die and a mold insert, wherein the lower die is arranged on a sliding block; the mold insert is L-shaped; the bottom of the inner side of the L-shaped mold insert is arranged on a sliding chute; a spring is pressed at the end part of the inner side of the L-shaped mold insert and at the outer side of the sliding chute and is arranged in the sliding chute; and the bottom of the outer side of the L-shaped mold insert is pressed on the inclined plane of the sliding block. The rear die inclined elastic structure is characterized in that an inclined wedge is arranged in the upper die; the upper half part of the inclined wedge is in a straight tube shape; the part in the straight tube shape is in sliding fit with the lower die; the lower part in a straight tube shape is an inclined straight part which penetrates through the sliding block and then penetrates out of the lower end of the inclined straight part; and the inclined wedge is ensured to upwards move to drive the L-shaped mold insert to be separated from the workpiece during die stripping by using the included angle between the inclined straight part and the combined surface between the sliding block and the L-shaped mold insert.
Description
Technical field
The present invention relates to the parts of mould of plastics, the back mould that is specially a kind of inverted L shape workpiece die for processing tiltedly plays structure.
Background technology
The back mould of existing inverted L shape workpiece die for processing tiltedly plays structure, it comprises upper die and lower die, mold insert, described counterdie is installed on slide block, described mold insert is the L type, the bottom of the inboard of L type mold insert is installed on chute, and in the outside of chute, the end of described L type mold insert inboard is pressed with spring, described spring is installed on described groove, and the bottom in the outside of described L type mold insert press-fits the inclined-plane in slide block.Its demoulding is that the pull by spring is realized the die sinking of mould and resetted, and spring occurs easily wearing and tearing, thereby has influence on the reliability of die sinking after action repeatedly.
Summary of the invention
At the problems referred to above, the back mould that the invention provides inverted L shape workpiece die for processing tiltedly plays structure, and its die sinking, matched moulds are reliable, convenient, fast.
Its technical scheme is such: it comprises patrix, counterdie, mold insert, described counterdie is installed on slide block, described mold insert is the L type, the bottom of the inboard of L type mold insert is installed on chute, the outside at chute, the end of described L type mold insert inboard is pressed with spring, described spring is installed on described groove, the bottom in the outside of described L type mold insert press-fits the inclined-plane in slide block, it is characterized in that: be equipped with tiltedly in the described patrix and carve, the described first half of tiltedly carving is a straight-tube shape, be slidingly matched between the position of described straight-tube shape and the described counterdie, lower end from described tiltedly straight portion passes behind the described slide block for oblique straight portion is passed in the bottom of described straight-tube shape, tiltedly carves up drive L type mold insert when the angle between the faying face between described tiltedly straight portion and slide block and the L type mold insert is guaranteed the demoulding and workpiece separates.
After the present invention adopts said structure, like this when the demoulding,, realize the demoulding fast and reset by tiltedly carving the acting in conjunction with spring, the reliability height, thus avoided in the prior art, depend spring alone and realize the demoulding, reset the shortcoming of poor reliability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
See Fig. 1, the present invention includes patrix 4, counterdie 7, mold insert 9, counterdie 7 is installed on slide block 2, mold insert 9 is the L type, the bottom of the inboard of L type mold insert 9 is installed on chute 6, the outside at chute 6, the end of L type mold insert 9 inboards is pressed with spring 8, spring 8 is installed on chute 6, the bottom in the outside of L type mold insert 6 press-fits the inclined-plane 10 in slide block 2, be equipped with tiltedly in the patrix 4 and carve, tiltedly carve the first half 3 and be straight-tube shape, be slidingly matched between straight-tube shape position 3 and the counterdie 7, straight-tube shape bottom 3 is passed slide block 2 backs for tiltedly straight portion 1 and is passed from the lower end of tiltedly straight portion 1, tiltedly carves up drive L type mold insert 9 when the angle between the faying face between tiltedly straight portion 1 and slide block 2 and the L type mold insert 9 is guaranteed the demoulding and workpiece 5 separates.Patrix 4 is up, and simultaneously, patrix 4 drives tiltedly to carve and moves upward, the vertical tube part of tiltedly carving 3 is up along counterdie 7, and the tiltedly straight portion 1 in the bottom of tiltedly carving this moment drives slide block 2 integral body to a side shifting, is to be moved to the left among Fig. 1, meanwhile, spring 8 promotes mold insert 9, moves along chute 6, drives workpiece 5 like this, from patrix 4, throw off, whole process is quick and easy, thereby can realize the die sinking of mold insert and reset the reliability height.
