Abstract
The present invention relates to a kind of spring mold ejection mechanisms.Including upper mold, lower mold, the lower mold both sides are internally provided with cavity, and the lower mold middle section is set as drag area, and cross bar is provided below in drag area, and the cross bar is provided at both ends with the strut across cavity;Upward mandril A is riveted respectively at one third and at 2/3rds among the cross bar and mandril B, the mandril A and mandril B pass through drag area bottom;The cross bar lower surface setting is located among cross bar there are three protrusion and both ends, protrusion is provided with spring above;The upper mold is accordingly just provided with model area with lower mold, and compression bar is additionally provided at the upper mold both ends face cavity.By simple mechanical fitting, mandril, by mould ejection, avoids deformation and damage mold, mold accuracy is ensure that, to reach production requirement under the action of spring restoring force.
Description
Technical field
The present invention relates to technical field of mold, especially a kind of spring mold ejection mechanism.
Background technology
Accurate forging die refers to being obtained with definite shape by die forging after high-temperature metal raw material is put into metal pattern
Product device.In fact in order to control the temperature of mold, also having on mold makes the cooling hole that refrigerant passes through, heater etc.
Device.The material for having become melt enters model area, and mold is opened after cooling stage, and the liftout attachment on molding machine can be
Knock-pin ejects, and product is released.When taking out workpiece, while to meet sliding block in place and cover half is inserted into sliding block, and it cannot
There is excessive gap to will produce product flash, increases the machining accuracy of mold difficulty and each part.Injection mold top at present
Go out device mostly to eject mold from mold slots using mandril, since mandril under a certain pressure may become mold top
Shape, or damage mold, influence mold accuracy, to fail to meet production requirements.
Invention content
It is an object of the invention to overcome the prior art, a kind of spring mold ejection mechanism is provided.
The purpose of the present invention is achieved through the following technical solutions:A kind of spring mold ejection mechanism.Including upper mold,
Lower mold, the lower mold both sides are internally provided with cavity, and the lower mold middle section is set as drag area, drag area
Cross bar is provided below, the cross bar is provided at both ends with the strut across cavity;Among the cross bar at one third and three points
Two at rivet upward mandril A and mandril B, the mandril A and mandril B respectively and pass through drag area bottom;Under the cross bar
Surface setting is located among cross bar there are three protrusion and both ends, protrusion is provided with spring above;The upper mold and lower die
The corresponding place of tool is provided with model area, and compression bar is additionally provided at the upper mold both ends face cavity.
Further, forced contact block is installed at the top of the strut.
Further, the upper model area and drag area inside engraving are provided with the model of demand.
Further, the strut, mandril A, mandril B and cross bar position steel material.
Further, support chip is riveted between the mandril A and the tops mandril B.
The present invention has the following advantages:By simple mechanical fitting, mandril is under the action of spring restoring force by mold
Ejection avoids deformation and damage mold, mold accuracy is ensure that, to reach production requirement.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention;
In figure:Mold under 1-, 2- upper molds, 3- drags area, the upper model areas 4-, 5- support chips, 6- protrusions, 7- springs, the tops 8-
Bar B, 9- cross bar, 10- mandrils A, 11- strut, 12- forced contact blocks, 13- cavitys, 14- compression bars.
Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to following institute
It states.
As shown in Figure 1, a kind of spring mold ejection mechanism, it includes upper mold 2, lower mold 1,1 liang of the lower mold
Side is internally provided with cavity 13, and 1 middle section of lower mold is set as drag area 3, and cross bar is provided below in drag area 3
9, the cross bar 9 is provided at both ends with the strut 11 across cavity 13;It is punished with 2/3rds at 9 intermediate one third of the cross bar
Upward mandril A10 is not riveted and mandril B8, the mandril A10 and mandril B8 pass through 3 bottom of drag area;Under the cross bar 9
Surface setting is located among cross bar 9 there are three protrusion 6 and both ends, protrusion 6 is provided with spring 7 above;The upper mold 2
Place corresponding with lower mold 1 is provided with upper model area 4, and compression bar 14 is additionally provided at 2 both ends face cavity 13 of the upper mold.
11 top of the strut is equipped with forced contact block 12.The 3 inside engraving setting of the upper model area 4 and drag area
There is the model of demand.9 strut 11, mandril A10, mandril B8 and cross bar steel materials.The mandril A10 and the tops mandril B8
Support chip 5 is riveted between portion.
The course of work of the present invention is as follows:When upper mold 2 and lower mold 1 fasten, the compression bar at 2 both ends of upper mold is set
14 are deep into the cavity 13 at 1 both ends of lower mold, and under the effect of the pressure, strut 11 pushes cross bar 9 down so that spring 7
Generate deformation;After model casting is molded, upper mold 2 moves up.At this moment spring 7 restores deformation, and cross bar 9 moves up,
Under the collective effect of mandril A10 and mandril B8, support chip 5 ejects shaping workpiece.
