Abstract
The utility model provides an interior hook strip product that draws of placing slider in is out of shape demoulding mechanism, including the slider, to one side the guide pillar, guide pillar fixing base, slider are led slider, drag hook, drag hook and are led slider and spring to one side, the slider install on the core, be provided with oblique guide pillar at slider both sides end, the guide pillar links to each other through oblique guide pillar fixing base and die cavity to one side, the drag hook is led the slider through the drag hook and is installed on the core of the bottom of slider, and drag hook one end is protruding step, and the spring of the drag hook other end passes through the fix with screw on the core. Demoulding mechanism uses oblique guide pillar as power, drives the slider motion of loosing core during the die sinking, looses core this in -process at the slider and accomplishes the process of drag hook pulling product deformation drawing of patterns.
Description
Technical field
The utility model belongs to injection mould field, is specifically related to a kind of drag hook band deformation of products mould emptier being built in slide block.
Background technology
In the process of Design of Plastic Mould, often can need do slide block or slant-top core-pulling because product structure requires.If the outside of core-pulling member needs slipper block loose core, inner side also needs to increase ramp-roof structure, but due to interiors of products limited space, design oblique top rear mold does not have enough intensity, and there is the region that can be out of shape back-off position.Need in this case to use slide block and slant-top core-pulling, the bulk strength of mould will inevitably be made to be affected, therefore need searching one to meet and loose core and can not make the affected a kind of core-pulling mechanism of mould strength.
Utility model content
For the technological difficulties of above-mentioned existence; the object of utility model is to design a kind of drag hook band deformation of products mould emptier being built in slide block; can meet and loose core and can not make mould strength to be affected; and make mold integral structure more simple and stable; locked mode is safer, accurate with reset, and die life is longer.
Above-mentioned purpose, is achieved through the following technical solutions:
Be built in a drag hook band deformation of products mould emptier for slide block, it is characterized in that: include slide block, Angle Pin, Angle Pin holder, slide block slider guide, drag hook, drag hook slider guide and spring; Described slide block is arranged on core, and slide block two side ends is provided with Angle Pin, and Angle Pin is connected with die cavity by Angle Pin holder; Drag hook is arranged on the core of the bottom of slide block by drag hook slider guide, drag hook one end is raised step, and the spring of the drag hook other end is fixed by screws on core.
Further, location bead is provided with bottom described drag hook.
Adopt the mould emptier of said structure, slide block is arranged on core; Drag hook is arranged on the core of the bottom of slide block, and determines position and the number of drag hook according to the position of back-off boss.Slide block by Angle Pin active force and start to loose core action time, drag hook because be fixed on core do not have power resources to start time be tending towards static.When slide block movement is to certain stroke, slide block encounters the raised step of drag hook, drag hook then and then the slide block segment distance that reruns make whole core-pulling mechanism depart from product completely, and drag hook is positioned at inside product, because the elasticity factor product of plastics is then pulled out of shape, now carrying out ejecting, can in order to avoid the back-off region of product be scraped off or drawing crack.When slide block resets, drag hook is static under the effect of location bead, and when slide block runs to certain position, slide block resets together with drag hook, and after slide block resets completely, drag hook also completes thorough reset under the action of the spring.
If do not consider the core-pulling mechanism design being built in slide block with drag hook, due to the limitation of die space, the cost of mould will inevitably be made to increase, bulk strength is affected, complex structure when can cause Design of Dies thus, movable function part is too much, have impact on life-span and the stability in use of mould to a great extent.
Superiority of the present utility model is:
1, drag hook is built in the mould emptier of slide block, simplifies the space structure of mould, and production cost is declined, and is also convenient to the precision that maintenance ensure that simultaneously.
2, a power has inputted process of loosing core for twice, improves efficiency, and makes the process of loosing core steady, smooth and easy.
3, the design concept that drag hook is built in the mould emptier of slide block has broken conventional thoughtcast of loosing core, and expands range of application, has novel innovative significance and market application foreground widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the utility model hook structure schematic diagram;
Fig. 4 is structural representation after the utility model demoulding.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-4, a kind of drag hook band deformation of products mould emptier being built in slide block, comprises slide block 1, Angle Pin 2, Angle Pin holder 3, slide block slider guide 5, drag hook 6, drag hook slider guide 7, spring 8.
Slide block 1 is arranged on core, and slide block 1 two side ends is provided with Angle Pin 2, and Angle Pin 2 is connected with die cavity by Angle Pin holder 3, and when mould is opened, Angle Pin 2 provides power resources for slide block 1.Drag hook 6 is arranged on the bottom core of slide block 1 by drag hook slider guide 7, and determines position and the number of drag hook 6 by the position of back-off boss.Drag hook 6 one end is raised step 61, and the spring 8 on drag hook 6 other end is fixed on core by screw 9, for providing power when slide block drag hook resets.Location bead 10 is provided with bottom described drag hook 6.
When slide block 1 starts to loose core action along the direction that its slide block slider guide 5 is specified by the active force of Angle Pin 2 during die sinking, drag hook 6 because be fixed on core do not have power resources to start time be tending towards inactive state.When slide block 1 moves to certain stroke, slide block 1 encounters the step 61 of the projection of drag hook 6, drag hook 6 and then slide block 1 reruns a segment distance, and drag hook 6 is positioned at inside product, because the elasticity factor product of plastics is then pulled out of shape, now carrying out ejecting, can in order to avoid the back-off region of product be scraped off or drawing crack.When slide block 1 resets, drag hook 3 is static under the effect of location bead 10, and when slide block 1 runs to certain position, slide block 1 resets together with drag hook 6, and after slide block 1 resets completely, drag hook 6 also completes thorough reset under the effect of spring 8.
Claims (2)
