Abstract

An inside and outside barb plastic die demoulding mechanism comprises an upper bottom board and a lower bottom board, wherein the upper bottom board is connected with a die cavity, a sprue sleeve is installed in the upper bottom board, a die foot and a pushing plate are installed on the lower bottom board, a die core is installed on the die foot, the die core and the die cavity form a die cavity, a finished product is arranged in the die cavity, an inside barb and an outside barb are manufactured inside and outside one point position of the finished product, an outer sliding block is installed in the die cavity, the outer sliding block and the outer barb are matched, the bottom of the outer sliding block is provided with an outer gear rack, an inner sliding block is installed in the die core, the inner sliding block and the inner barb are matched, a distance L is arranged between the inside of the inner sliding block and the die core, an inner gear rack is manufactured on the inner sliding block, the inner gear rack and the outer gear rack are meshed through a gear, and an inclined guiding post is installed in the die cavity and penetrates through the outer sliding block. The solution is particularly applicable in the occasions that dies must adopt outward drawing core sliding block mechanisms, however inside inclined pushing blocks can not be distributed, the demoulding of the finished product is stable, the die service life is long, and the production efficiency is high.

Description

Barb demould of plastic mould mechanism outside interior

Technical field

The utility model relates to the mould emptier of mould of plastics, is applicable to that mainly all there is the structure of barb in the interior outside in goods same point position, as automotive plastic parts, motorcycle plastic spare, household appliances working of plastics etc.

Background technology

Along with popularization and the improving constantly of instructions for use of plastic products in industry, life are used, the structure of plastic products more and more is tending towards complicated variation.Plastic products all have the structure of depanning barb also to be used widely at same position, and the mechanism that this based article structure realizes in mold releasability generally adopts the external application slide block of loosing core, the inboard slanted kicking block that adopts, promptly in the outer structure of taking out in top.But often there is following difficulty in the structure of taking out outside the top in adopting in the actual mould design: one, mould does not have enough spaces to arrange outer slide and interior jacking block simultaneously on goods same point position; Two,, interior slanted kicking block is made than large span " 7 " character form component sometimes, but this structure has a strong impact on the intensity and the life-span of mould for dodging outer slide mechanism.Therefore, pump structure outside traditional interior top, unsatisfactory in many occasion results of use, sometimes even can't realize.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art; provide a kind of inner and outer slider that drives same position on the mould by gear and rackwork by same power to do the demoulding campaign of different directions simultaneously, the interior outside barb demould of plastic mould mechanism that makes that the goods demoulding is steady, die life is long, production efficiency is high.

The technical scheme of outside barb demould of plastic mould mechanism is in the utility model: comprise upper plate and lower shoe; upper plate connects die cavity; sprue bush is installed in the upper plate; mould pin and top board are installed on the lower shoe; on the mould pin core is installed; core and die cavity constitute die cavity; goods are arranged in the die cavity; in the goods same point position; in the outside is shaped on; outer barb is characterized in that in the described die cavity outer slide being installed, and outer slide matches with outer barb; the bottom of outer slide is shaped on outer tooth bar; inner slide is installed in the described core, and inner slide matches with interior barb, and spacing L is arranged between the inboard of inner slide and the core; be shaped on interior tooth bar on the inner slide; through gears engaged, Angle Pin is installed in die cavity between interior tooth bar and the outer tooth bar, Angle Pin penetrates in the outer slide.

Barb demould of plastic mould mechanism in the outside in of the present utility model; during the demoulding; at first drive die cavity and core die sinking by injection machine; the Angle Pin that is installed in the die cavity drives outer slide to the mould movement outside; make outer slide demoulding from outer barb; outer slide is at the outer tooth bar bottom itself in the mould movement outside and be installed in the gears engaged on the tooth bar in the inner slide; driven gear rotates; and the interior tooth bar of gears engaged then drives the spacing (mould inboard) of inner slide between inner slide and core and slides; make inner slide demoulding from interior barb, thereby finish the plastic products mould in same position; outer slide utilizes same power to drive the demoulding of finishing the overhead structure goods simultaneously.The occasion of loosing core slide block mechanism outside this programme is specially adapted to must adopt but can't arrange inboard slanted kicking block on mould makes that the goods demoulding is steady, die life is long, production efficiency is high.

Barb demould of plastic mould mechanism in the outside in of the present utility model, the inboard of its described inner slide and the spacing L between the core are the degree of depth of interior barb, reduce the gap, make the mould compactness.On its core limited block is installed, limited block contacts with inner slide, prevents from that inner slide from skidding off to pull goods outside mould, avoids damaging goods.

Description of drawings

Fig. 1 is an outside barb demould of plastic mould mechanism structure schematic diagram in the utility model.

The specific embodiment

The utility model relates to the mould emptier of a kind of interior outside barb mould of plastics; as shown in Figure 1; comprise upper plate 1 and lower shoe 10; upper plate connects die cavity 12; sprue bush 13 is installed in the upper plate; mould pin 8 and top board 9 are installed on the lower shoe 10; core 11 is installed on the mould pin; core 11 and die cavity 12 constitute die cavity; goods 14 are arranged in the die cavity; in the goods same point position; in the outside is shaped on; outer barb 15; 16, it is characterized in that outer slide 3 is installed in the described die cavity 12, outer slide 3 matches with outer barb 16; the bottom of outer slide is shaped on outer tooth bar 4; in the described core 11 inner slide 7 is installed, inner slide matches with interior barb 15, between the inboard of inner slide 7 and the core 11 spacing L is arranged; tooth bar 6 in being shaped on the inner slide; through gear 5 engagements, Angle Pin 2 is installed in die cavity 12 between interior tooth bar 6 and the outer tooth bar 4, Angle Pin 2 penetrates in the outer slide 7.During the demoulding, at first drive die cavity 12 and core 11 die sinkings by injection machine, the Angle Pin 2 that is installed in the die cavity 12 drives outer slide 3 to the mould movement outside, make outer slide 3 demoulding from outer barb 16, outer slide 3 is at the outer tooth bar bottom itself 4 in the mould movement outside and be installed in 5 engagements of the gear on the tooth bar 6 in the inner slide 7, driven gear 5 rotates, and 6 of the interior tooth bars of gear 5 engagements drive the spacing (mould inboard) of inner slide 7 between inner slide and core and slide, make inner slide 7 demoulding from interior barb 15, thereby finish the plastic products mould in same position, outer slide utilizes same power to drive the demoulding of finishing the overhead structure goods simultaneously.The occasion of loosing core slide block mechanism outside this programme is specially adapted to must adopt but can't arrange inboard slanted kicking block on mould makes that the goods demoulding is steady, die life is long, production efficiency is high.Spacing L between the inboard of its described inner slide 7 and the core 11 is the degree of depth of interior barb 15, reduces the gap, makes the mould compactness.Limited block 17 is installed on its core 11, and limited block 17 contacts with inner slide 7, prevents from that inner slide 7 from skidding off to pull goods outside mould, avoids damaging goods.
