Abstract
The utility model discloses an elastic ejection resetting mechanism for internal parting bumpers, which comprises a die upper template and a die lower template, wherein the upper template is connected with a cavity, the lower template is provided with die legs, a mold core is arranged on the die legs, a formed bumper product is arranged between the mold core and the cavity, an upper ejection plate and a lower ejection plate are arranged between the die legs, an inclined sliding seat is arranged in the upper ejection plate, the inclined sliding seat is connected with an inclined ejection rod, the inclined ejection rod is connected with an inclined ejection block, the outer side of the inclined ejection block is provided with an internal drawing block, and the bottom of the internal drawing block is provided with a nitrogen spring and is positioned in the mold core through a positioning bar; and the elastic ejection resetting mechanism is characterized in that: an elastic medium is arranged between the internal drawing block and the molded surface of the inclined ejection block, and the elastic medium is a compression spring or an elastic block or a nitrogen spring. In the process of resetting, the molded surface of the inclined ejection block and the elastic medium arranged in the internal drawing block are in contact for resetting firstly, thereby avoiding the occurrence of collision and friction; and no flash edge is produced on the molded surfaces of the inclined ejection block and the internal drawing block, thereby prolonging the service lives of dies.
Description
Technical field
The utility model relates to a kind of interior somatotype bumper elasticity and ejects resetting-mechanism, belongs to the mould of plastics field.
Background technology
At present, bumper mold generally all adopts interior somatotype structure, and it ejects to move and is: at first mould die sinking; Die cavity is opened, and simultaneously, the injection machine ejection system is progressive synchronously; Promote the upper and lower top board of mould and oblique slide drives angle ejector rod and slanted kicking block begins to eject, simultaneously, in take out piece under the elastic reaction of nitrogen spring; Begin the action of loosing core synchronously, when the backstay of nitrogen spring with after the core bottom surface contacts, in take out piece and stop action; But other mechanism relies on the mechanical action of injection machine to continue to eject, to reach ejection stroke.But, when resetting, slanted kicking block with in take out piece profile contact for a long time, overlap is produced in and friction easily, influences die life.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, provides a kind of and between interior profile of taking out piece and slanted kicking block, elastic fluid is set, and reduces friction, and the interior somatotype bumper elasticity that prolongs die life ejects resetting-mechanism.
The technical scheme that the interior somatotype bumper elasticity of the utility model ejects resetting-mechanism is: comprise upper mould plate and lower bolster, cope match-plate pattern connects die cavity, and the mould pin is installed on the lower bolster; On the mould pin core is installed, the bumper product of moulding is arranged between core and the die cavity, upper plate and lower roof plate are set between the mould pin; Oblique slide is installed in the upper plate; Tiltedly connect angle ejector rod on the slide, angle ejector rod connects slanted kicking block, takes out piece in the arranged outside of slanted kicking block; In take out piece bottom nitrogen spring be installed; And be positioned in the core by backstay, to take out in it is characterized in that between the profile of piece and slanted kicking block elastic fluid is set, described elastic fluid is compression spring or elastomer block or nitrogen spring.
The interior somatotype bumper elasticity of the utility model ejects resetting-mechanism, during work, and at first mould die sinking; Die cavity is opened, and simultaneously, the injection machine ejection system is progressive synchronously; Promote the upper and lower top board of mould and oblique slide drives angle ejector rod and slanted kicking block begins to eject, simultaneously, in take out piece under the elastic reaction of nitrogen spring; Begin the action of loosing core synchronously, when the backstay of nitrogen spring with after the core bottom surface contacts, in take out piece and stop action; But other mechanism relies on the mechanical action of injection machine to continue to eject, to reach ejection stroke.Owing between interior profile of taking out piece and slanted kicking block, be provided with elastic fluid; Described elastic fluid is compression spring (Hookean spring) or elastomer block (plastics spring) or nitrogen spring (nitrogen cylinder); When resetting, the profile of slanted kicking block be installed in take out elastic fluid in the piece and contact in advance and reset, avoid collision, friction; Slanted kicking block with in take out piece profile do not produce overlap, prolong die life.
The interior somatotype bumper elasticity of the utility model ejects resetting-mechanism, takes out in described and is shaped on spring eye on the piece, and the compression spring is installed in the spring eye; And fix by fixed bar; The top of compression spring contacts with the profile of slanted kicking block, and spring eye has been arranged, and the compression spring is easy for installation, firm.
Description of drawings
Fig. 1 is that somatotype bumper elasticity ejects the resetting-mechanism structural representation in the utility model.
The specific embodiment
The utility model relates to a kind of interior somatotype bumper elasticity and ejects resetting-mechanism, and is as shown in Figure 1, comprises upper mould plate 1 and lower bolster 2; Cope match-plate pattern connects die cavity 3, and mould pin 4 is installed on the lower bolster, and core 10 is installed on the mould pin; The bumper product 11 that moulding is arranged between core 10 and the die cavity 3 is provided with upper plate 5 and lower roof plate 6 between the mould pin, oblique slide 7 is installed in the upper plate 5; Tiltedly connect angle ejector rod 8 on the slide, angle ejector rod 8 connects slanted kicking block 9, takes out piece 12 in the arranged outside of slanted kicking block 9; In take out piece 12 bottoms nitrogen spring 13 be installed; And be positioned in the core 10 by backstay 14, to take out in it is characterized in that between the profile of piece 12 and slanted kicking block 9 elastic fluid is set, described elastic fluid is compression spring 15 or elastomer block or nitrogen spring.During work, at first mould die sinking, die cavity 3 is opened; Simultaneously, the injection machine ejection system is progressive synchronously, and the upper and lower top board 5,6 of promotion mould and oblique slide 7 drive angle ejector rods 8 and slanted kicking block 9 begin to eject; Simultaneously, in take out piece 10 under the elastic reaction of nitrogen spring 13, begin the action of loosing core synchronously; When the backstay 14 of nitrogen spring 13 with after core 10 bottom surfaces contact, in take out piece 12 and stop action, but other mechanism relies on the mechanical action of injection machine to continue to eject; Reaching ejection stroke, owing between interior profile of taking out piece 12 and slanted kicking block 9, be provided with elastic fluid, described elastic fluid is for compressing spring (Hookean spring) or elastomer block (plastics spring) or nitrogen spring (nitrogen cylinder); When resetting, the profile of slanted kicking block be installed in take out elastic fluid in the piece and contact in advance and reset, avoid collision, friction; Slanted kicking block with in take out piece profile do not produce overlap, prolong die life.Take out in described and be shaped on spring eye 16 on the piece 12, compression spring 15 is installed in the spring eye 15, and is fixed by fixed bar 17, and the top of compression spring 15 contacts with the profile of slanted kicking block 9, and spring eye has been arranged, and the compression spring is easy for installation, firm.
