Description
Technical field
The present invention relates to injection mold, more particularly, relate to a kind of interior deduction for injection mold.
Background technology
Deduction is used for control die sinking step in mould, generally be installed in the mould outside, is called to be the formula deduction that leaks outside.The formula deduction of leaking outside is mainly used in loosing core earlier for needs, in the mould of back die sinking, is used for the different die sinking order of control different templates.As shown in Figure 1, be used in assembly structure schematic diagram on the concrete mould for the formula deduction that leaks outside.
Be illustrated in figure 2 as the structure chart of the formula deduction that leaks outside, deduction positioning seat 21 has dug deduction hole 211 and tie rod hole 212, and deduction 24 and deduction pull bar 20 pass deduction hole 211 and tie rod hole 212 respectively.The size in described deduction hole 211 is greater than the cross section outer profile size of deduction 21, and the size of described tie rod hole 212 just satisfies deduction pull bar 20 and axially moves along tie rod hole 212.
Described chute 210 left sides have shoulder hole 213, in the described shoulder hole 213 flexible member 23 are housed.Described chute 210 communicates with tie rod hole 212, and described deduction pull bar 20 is provided with the breach 200 that matches with small slide block 22 outlines.
Described small slide block 22 has connection to go up the inclined-plane 221 of bottom surface and peripheral contoured surface, and there is ledge 201 described deduction pull bar 20 lower ends, and described ledge 201 comprises the outstanding inclined-plane 202 that coincide with inclined-plane 221 shapes.Described deduction pull bar 20 upper ends are provided with for the fixing pull bar fixed part 203 of deduction pull bar 20.
Described deduction 24 upper ends are provided with outer rim 240, and the lower end of described deduction 24 is provided with for the fixing deduction fixed part 241 of deduction 24.
During original state, flexible member 23 is in pressured state, and breach 200 is not aimed at chute 210.The position of deduction pull bar 20 can be adjusted according to the actual conditions needs.Deduction 24, deduction positioning seat 21 and deduction pull bar 20 are fixedly mounted on respectively on the different templates.
The template motion drives deduction 24, deduction positioning seat 21 and 20 motions of deduction pull bar.After deduction pull bar 20 moved to certain position, breach 200 was aimed at chute 210, and small slide block 22 is advanced breach 200 by flexible member 23.Deduction pull bar 20 is stuck, and deduction positioning seat 21 and deduction pull bar 20 place template relative positions are constant, and deduction 24 place templates then can continue motion and be blocked by small slide block 22 until deduction 24.The different die sinking demands of control different templates have so just been reached.
The formula that leaks outside deduction is installed the template outside, can only be used for fastening template, with the motion of restriction template.And template was opened the certain distance demoulding afterwards earlier before and after inner core rod needed in a lot of moulds, could guarantee the smooth demoulding of product.At this moment just need there be a mechanism to come the motion of restricted internal core rod.And the formula deduction of leaking outside can only limit the motion of template, and internal mechanism is not played any effect.
Summary of the invention
The technical problem to be solved in the present invention is,, provides to be arranged on deduction in mould the inside a kind of to the defective that internal mechanism acts on without limits at the above-mentioned formula deduction that leaks outside of prior art.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of interior deduction that can control mould die sinking order, the interior deduction that makes the die sinking of core rod and template substep, described mould comprises the hot runner manifold that is fixedly mounted between panel and the A plate, hot runner manifold has dug through hole, panel and A plate are equipped with cut-out in the corresponding positions with the through hole of hot runner manifold and make panel, after assembling, hot runner manifold and A plate form one for the cavity of needle plate and preceding die face needle plate at the bottom of the installation front mould, needle plate and preceding die face needle plate are fixed together at the bottom of the front mould, can move up and down along cavity, be installed in ejector retainner plate guide pillar on the panel and pass that needle plate and preceding die face needle plate insert the A plate at the bottom of the front mould, be installed in that die face needle plate and A plate insert the B plate before the release link on the needle plate is passed at the bottom of the front mould, oblique top is fixedly mounted on the preceding die face needle plate by angle ejector rod
The stiff end of deduction is embedded in the A plate and fixedly mounts in described, and described interior deduction passes slide block positioning seat and the slide block that slide block is housed; Flexible member is equipped with in the one end outside of described slide block, and the described slide block other end stretches out the crook that the slide block positioning seat blocks release link.
In of the present invention in the deduction, described slide block positioning seat is fixed in the B plate and between B plate and A plate.
In the deduction, described slide block positioning seat is provided with the interior deduction hole for deduction in installing in of the present invention, and described B plate is provided with cavern part below the slide block positioning seat, and the free end of interior deduction is arranged in cavern part.
