The center base plate is connected with a power device, and a center is installed on the center fixing plate. A mold core insert is installed in the moving template, a clamping slot is installed on the lateral wall of the mold core insert, a clamp ring formed through injection molding is arranged between the mold core insert and the cavity, a reversed buckle is manufactured at the upper end of the clamp ring, and a clamp buckle is manufactured at the lower end of the clamp ring. The secondary forced demolding ejection mechanism of the plastic pipe mold is characterized in that a spring is installed in the moving template and contacted with the bottom of the mold core insert, and an ejector block is installed on the mold core insert and fixed with the center through screws.

Description

Plastic pipe mould secondary takes off ejecting mechanism by force

Technical field

The utility model relates to the plastic pipe mould and takes off ejecting mechanism by force, particularly relates to plastic pipe mould secondary and takes off ejecting mechanism by force.

Background technology

The plastic pipe mould is being shaped on product that the back-off lower end is shaped on the whole circle of buckle when carrying out the demoulding to the upper end, conventional design is to realize a step demoulding, easily product is caused damage if take off then by force.

Summary of the invention

The purpose of the utility model is in order to overcome the shortcoming that prior art exists, a kind of substep demoulding to be provided, and makes the upper end be shaped on product stripping that the back-off lower end is shaped on the whole circle of buckle fast, plastic pipe mould secondary takes off ejecting mechanism by force smoothly.

The technical scheme that the utility model plastic pipe mould secondary takes off ejecting mechanism by force is: comprise solid plate and moving platen, under solid plate, be shaped on die cavity, moving platen is installed the mould pin down; Base plate is installed in the mould underfooting, between base plate and moving platen, is equipped with Ejector Retainer Plate and thimble fixed head, and Ejector Retainer Plate connects power set; On the thimble fixed head thimble is installed, core is installed in moving platen is inserted, the core sidewall of inserting has buckle slot; Core insert and die cavity between the collar of injection mo(u)lding is arranged, said collar upper end is shaped on back-off, the collar lower end is shaped on buckle; It is characterized in that mounting spring in the said dynamic model; The pig that spring and core are inserted is installed jacking block on core is inserted, jacking block fixes through screw and thimble.

The utility model discloses a kind of plastic pipe mould secondary and take off ejecting mechanism by force, during the demoulding, move down by power drive moving platen and base plate earlier and carry out die sinking; In die sinking, the spring in the moving platen upwards ejects core and inserts under the effect of elastic force, and core is inserted and driven collar and move up; Make the cambered surface in the buckle outside, collar lower end break away from moving platen, power set drive Ejector Retainer Plate and thimble fixed head move up then, and the thimble fixed head drives thimble and moves up; Thimble upwards promotes jacking block, because the collar upper end is shaped on back-off, back-off is buckled on the jacking block; Jacking block drives collar upwards when moving up, collar under the promotion of jacking block, the buckle slot that the buckle of collar lower end forces core to be inserted; Last collar is fallen into downwards in the collecting box, accomplishes the demoulding, is divided into for two steps to make the upper end be shaped on the product stripping that the back-off lower end is shaped on the whole circle of buckle; The demoulding guarantees the quality of product fast, smoothly.

The utility model plastic pipe mould secondary takes off ejecting mechanism by force, each mounting guide sleeve during said moving platen and core are inserted.Guide pin bushing has been arranged, contacted with guide pin bushing when thimble moves up and down, anti-wear performance is good, improves the service life that moving platen and core are inserted.Said core is inserted and is divided into that core is inserted and following core is inserted.Manufacturing, easy for installation.

Fig. 2 is that core that plastic pipe mould secondary takes off ejecting mechanism is by force inserted and ejected the status architecture sketch map;

Fig. 3 is that the jacking block that plastic pipe mould secondary takes off ejecting mechanism by force ejects the status architecture sketch map.

The specific embodiment

The utility model relates to a kind of plastic pipe mould secondary and takes off ejecting mechanism by force, like Fig. 1-shown in Figure 3, comprises solid plate 1 and moving platen 2; Under solid plate, be shaped on die cavity 3, moving platen is installed mould pin 4 down, and base plate 5 is installed in the mould underfooting; Between base plate and moving platen, be equipped with Ejector Retainer Plate 6 and thimble fixed head 7, Ejector Retainer Plate connects power set, and thimble 8 is installed on the thimble fixed head; Core is installed in moving platen is inserted 9, the core sidewall of inserting has buckle slot 10, core insert and die cavity between the collar 11 of injection mo(u)lding is arranged; Said collar upper end is shaped on back-off 12, and the collar lower end is shaped on buckle 13, it is characterized in that mounting spring 14 in the said dynamic model; Insert 9 pig of spring and core is installed jacking block 15 on core is inserted, jacking block fixes through screw 16 and thimble 8.During the demoulding, move down with base plate 5 by power drive moving platen 2 earlier and carry out die sinking, in die sinking; Spring 14 in the moving platen 2 upwards ejects core and inserts 9 under the effect of elastic force, core is inserted and driven collar 11 and move up, and makes the cambered surface in buckle 13 outsides, collar lower end break away from moving platen 2; Power set drive Ejector Retainer Plate 6 moves up with thimble fixed head 7 then, and the thimble fixed head drives thimble 8 and moves up, and thimble upwards promotes jacking block 15; Because collar 11 upper ends are shaped on back-off 12, back-off is buckled on the jacking block 15, and jacking block drives collar 11 upwards when moving up; Collar is under the promotion of jacking block, and the buckle of collar lower end 13 forces core 9 the buckle slot 10 of inserting, and last collar 11 is fallen in the collecting box downwards; Accomplish the demoulding; Being divided into for two steps makes the upper end be shaped on the product strippings that back-off 12 lower ends are shaped on the whole circle of buckle 13, and the demoulding guarantees the quality of product fast, smoothly.Said moving platen 2 and core each mounting guide sleeve 17 in 9 of inserting.Guide pin bushing 17 has been arranged, contacted with guide pin bushing 17 when thimble 8 moves up and down, anti-wear performance is good, improves moving platen 2 and core and inserts service life of 9.Said core insert 9 be divided into core insert 18 with following core insert 19.Manufacturing, easy for installation.
