Abstract
The utility model relates to an ejecting device of an injection mould, which comprises a support shell, a tilting plate and pins, wherein a semi-circumferential groove is arranged in the middle of the upper end surface of the support shell, the side wall of the support shell is provided with a through hole, the lower end surface of the support shell is provided with two screw holes, the tilting plate is provided with a through hole and placed in the semi-circumferential groove, and the pins penetrate through the through holes and the screw holes. The ejecting device is reasonable in manufacture, stable in work, compact in structure, and convenient for processing and replacing, the design efficiency of the injection mould and the automatic production of parts are improved, and the ejecting device is easy to make standards so as to form series.
Description
Technical field
The present invention relates to a kind of parts of injection mold, relate in particular to a kind of liftout attachment of injection mold.
Background technology
When there is back-off the inside of injecting products, usually adopt the injection mold structure of taper pin inner core pulling, need to use taper pin to come these back-off positions of moulding, the mould that in the industry this class is had a taper pin is referred to as taper pin inner core pulling injection mold, this class mould structure relative complex need increase taper pin mechanism on mould.Taper pin length is longer usually, the molding structure of taper pin mechanism outside is more complicated often again, because taper pin also has gradient, therefore traditional pushing method is easy to cause the part and the taper pin that are ejected to move together, cause in the process of ejecting, the part thimble embeds in the part that is ejected, and blocks part.In order to solve this phenomenon that not exclusively ejects, the method that adopts is usually:
1. artificial pickup: be not suitable for production in enormous quantities, lavish labor on, operator's personal safety is constituted a threat to, also cause the quality and the potential safety hazard of mould.
2. manipulator pickup: though can realize in enormous quantities and automated production, stability is difficult to be guaranteed, and the raising of cost is simultaneously also brought burden to enterprise.
Summary of the invention
In view of the deficiency that prior art exists, it is a kind of under the prerequisite that guarantees product appearance, dimensional accuracy and die life that the object of the invention is to provide, and high efficiency is finished the efficient liftout attachment that the taper pin mould ejects part fully.
For achieving the above object, the present invention adopts following technical scheme: a kind of liftout attachment of injection mold, it is characterized in that: comprise support shell, seesaw, pin, center, described support shell upper surface is provided with the semi-circumference groove, the support shell sidewall is provided with first through hole, and the support shell lower surface is provided with two screw holes, and described seesaw is provided with second through hole, seesaw is placed in the semi-circumference groove, and described pin penetrates first through hole and second through hole.
Beneficial effect of the present invention is, this device is made rationally, working stability, and compact conformation, easy to process, be convenient to change, improve the automated production of design for Injection Mould efficient and part, and formulated standard easily, form series.

Among the figure: 1, support shell, 11, groove, 12, first through hole, 2, seesaw, 21, second through hole, 3, pin
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Shown in Fig. 1～5, the liftout attachment of injection mold comprises support shell 1, seesaw 2, pin 3, and center, support shell 1 upper surface is provided with a semi-circumference groove 11, support shell 1 upper portion side wall is provided with first through hole 12, and support shell 1 lower surface is provided with two screw holes; On the position of seesaw 2 relative first through holes 12, be provided with second through hole 21; Seesaw 2 is placed in the semi-circumference groove 11, and pin 3 penetrates first through hole 12 and second through hole 21, and fixedly seesaw 2.
In the groove that this device is installed on the thimble backboard 8 with this plant bulk conforms to, and fix, again spring, thimble are installed on the ejector retainner plate 7 corresponding positions, assemble mould with screw-driving.
In the course of work, when liftout plate 7 moves to respective distance, little push rod 4 contacts with moving platen 6, one end of this device seesaw 2 is in little push rod 4 and moving platen 6 compaction process, rotate in the semi-circumference groove 11 of support shell 1 around pin 3, the other end of seesaw 2 lifts, and ejects push rod 5, and push rod 5 cooperates other push rods together part to be ejected fully.Afterwards, liftout plate 7 resets under the effect of spring, waits for next process.
