Abstract
The invention discloses a plastic elbow mould pull rod inner pumping mechanism. The plastic elbow mould pull rod inner pumping mechanism comprises a mold cavity installed on a mould die carrier, wherein the cavity body of the mold cavity is provided with an elbow core, the elbow core can drive a loose core through a loose core oil cylinder, and the loose core oil cylinder is fixed on an oil cylinder plate; the oil cylinder plate is installed on the mould die carrier. The plastic elbow mould pull rod inner pumping mechanism is characterized in that the head of the elbow core is connected with a guide sloping block through an oblique I-shaped groove, and the head of the guide sloping block is connected with an elbow barb core; and the elbow core is provided with a sloping block push-out spring, the sloping block push-out spring is connected with a supporting block, the supporting block is contacted with the rear end part of the guide sloping block, the rear part of the guide sloping block is connected with a sloping block pull rod, and the other end of the sloping block pull rod is connected with the oil cylinder plate. The scheme adopts a pull rod to fix the sloping block, the reset action is stable and reliable, and a cavity body is not damaged.
Description
Technical field
The present invention relates to pulling mechanism in a kind of plastic elbow mould pull bar, belong to the mould of plastics field.
Background technology
Prior art adopts mould of plastics to produce plastic elbow, when the elbow fuse is loosed core the demoulding, because elbow has the barb place, what generally adopt is the twice core pulling mode of guiding skewback and barb fuse and the combination of elbow fuse, but when loosing core, guiding skewback and barb fuse can be beated, and when lead skewback and elbow fuse reset, the guiding skewback is to utilize spring to reset, and the elbow fuse is to be driven by the oil cylinder of loosing core to reset, there is asynchronous situation about resetting, easily runs into the die cavity cavity, damage cavity.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art, fixedly skewback of a kind of employing pull bar is provided, homing action is stable, reliable, avoids the interior pulling mechanism of plastic elbow mould pull bar of cavity damage.
The technical scheme of pulling mechanism is in the plastic elbow mould pull bar of the present invention: comprise the die cavity that is installed on the mould mould bases, the elbow fuse is set in the cavity of die cavity, the elbow fuse is driven by the oil cylinder of loosing core looses core, the oil cylinder of loosing core is fixed on the tank plate, tank plate is installed on the mould mould bases, it is characterized in that described elbow fuse head connects the guiding skewback through oblique I-shaped groove, the head connecting bend barb fuse of guiding skewback, in the described elbow fuse skewback ejector spring is set, the skewback ejector spring connects back-up block, back-up block contacts with guiding skewback rearward end, and connects the skewback pull bar at the rear portion of guiding skewback, and the other end of skewback pull bar connects tank plate.
Pulling mechanism in the plastic elbow mould pull bar of the present invention, because the rear portion at the guiding skewback has connected the skewback pull bar, when loosing core, because the effect of skewback pull bar (the skewback pull bar is held the guiding skewback), the elbow fuse after take out in, skewback ejector spring springing back-up block and guiding skewback can not move forward, but move up, avoided the barb place of cavity, so that loose core smoothly, and when resetting, same skewback pull bar is held the guiding skewback, make guiding skewback and elbow fuse synchronous reset, can not run into the die cavity cavity, action safety, reliable.
Pulling mechanism in the plastic elbow mould pull bar of the present invention, described skewback pull bar can be rope or zip etc., when loosing core, rope or zip are retracted, when resetting, rope or zip are held the guiding skewback, make guiding skewback and elbow barb fuse and elbow fuse synchronous reset.Described elbow fuse both sides are equipped with blade fin, and blade fin has been arranged, the elbow fuse stable action of loosing core.
Description of drawings
Fig. 1 is the pulling mechanism pre-structure schematic diagram of loosing core in the plastic elbow mould pull bar of the present invention;
Fig. 2 is the pulling mechanism rear structural representation of loosing core in the plastic elbow mould pull bar of the present invention.
The specific embodiment
The present invention relates to pulling mechanism in a kind of plastic elbow mould pull bar, such as Fig. 1, shown in Figure 2, comprise the die cavity 1 that is installed on the mould mould bases, in the cavity 2 of die cavity elbow fuse 3 is set, elbow fuse 3 is driven by the oil cylinder 4 of loosing core looses core, the oil cylinder of loosing core is fixed on the tank plate 5, tank plate 5 is installed on the mould mould bases, it is characterized in that described elbow fuse 3 heads connect guiding skewback 7 through oblique I-shaped groove 6, the head connecting bend barb fuse 8 of guiding skewback, in the described elbow fuse 3 skewback ejector spring 9 is set, skewback ejector spring 9 connects back-up block 10, back-up block 10 contacts with guiding skewback 7 rearward end, and connects skewback pull bar 11 at the rear portion of guiding skewback 7, and the other end of skewback pull bar 11 connects tank plate 5.This programme is owing to having connected skewback pull bar 11 at the rear portion of guiding skewback 7, when loosing core, because the effect of skewback pull bar 11 (skewback pull bar 11 is held guiding skewback 7), elbow fuse 3 after take out in, skewback ejector spring 9 springing back-up blocks 10 and guiding skewback 7 can not move forward, but move up, avoided the barb place of cavity 2, so that loose core smoothly, and when resetting, same skewback pull bar 11 is held guiding skewback 7, makes guiding skewback 7 and elbow fuse 3 synchronous resets, can not run into die cavity cavity 2, action safety, reliable.Described skewback pull bar 11 can be rope or zip etc., and when loosing core, rope or zip are retracted, and when resetting, rope or zip are held the guiding skewback, make guiding skewback and elbow barb fuse and elbow fuse synchronous reset.Described elbow fuse 3 both sides are equipped with blade fin 12, and blade fin has been arranged, the elbow fuse stable action of loosing core.
