For injection molding parts with complex structures, two mold cores need to be ejected out twice respectively; the conventional method is to take the first mold core off and then take the second mold core off; however, in order to improve the production efficiency, it is only necessary to ensure that the first mold core and the second mold core are separated, and a sufficient space for taking down the injection molding part is provided between the second mold core and the third mold core.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an ejecting mould of secondary.
The technical scheme of the utility model is that: the secondary ejection die comprises a die body and a die cover,
a first mold core;
a second mold core; a first ejector rod channel is arranged and penetrates through the second die core;
the third mold core and the first mold core are positioned at two sides of the second mold core and are respectively connected with the second mold core to form an injection molding cavity; the third die core is provided with a second ejector rod channel; the second ejector rod channel is right corresponding to the first ejector rod channel;
and the mold splitting ejector rod comprises a first ejector part and a second ejector part, and the distance between the tail end of the first ejector part and the tail end of the second ejector part along the ejection direction is greater than the thickness of the second mold core.
Further, the secondary ejection die comprises two die-separating ejector rods, and the two die-separating ejector rods are distributed on two sides of the secondary ejection die.
Furthermore, the die-splitting ejector rod further comprises a limiting elastic element, the second ejection part is a hinged inclined block, and the limiting elastic element is connected between the first ejection part and the hinged inclined block.
The beneficial effects of the utility model reside in that: the first die core and the second die core can be sequentially ejected, the structure is simple, the ejection distance of the second ejection part is equal to the distance between the second die core and the third die core, the ejection distance between the second die core and the third die core can be conveniently adjusted according to the size of an injection molding part, and the production efficiency is improved.

Detailed Description
In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will be described in further detail with reference to specific embodiments.
As shown in fig. 1 and 2, the double ejection mold 100 includes,
a first core 20;
a second mold core 30; a first ejector rod channel 31 is arranged; the first ejector rod channel 31 penetrates through the second die core 30;
the third mold core 40 and the first mold core 20 are positioned at two sides of the second mold core 30 and are respectively connected with the second mold core 30 to form an injection molding cavity, and the injection molding cavity is used for injection molding of parts; the third die core 40 is provided with a second ejector rod channel 41; the second ejector rod channel 41 is opposite to the first ejector rod channel 31, so that the die parting ejector rod 50 can sequentially pass through the second ejector rod channel 41 and the first ejector rod channel 31 and stop against the first die core 20;
the mold splitting ejector rod 50 comprises a first ejector part 51 and a second ejector part 52, and the distance between the tail end of the first ejector part and the tail end of the second ejector part along the ejection direction a is greater than the thickness of the second mold core 30; therefore, the tail end of the first ejection part can only stop against the second mold core 30 after the first mold core 20 is ejected out of the tail end of the first ejection part and moves for a certain distance, so that the mold splitting ejector rod 50 ejects the first mold core 20 and the second mold core 30 twice along the same ejection direction respectively, the structure is simple, and the secondary ejection is convenient and reliable; the injection molding part has high production efficiency.
As shown in fig. 1 and fig. 2, the secondary ejection mold 100 includes two mold split ejector rods 50, and the two mold split ejector rods 50 are distributed on two sides of the secondary ejection mold 100; therefore, the stress for ejecting the first mold core 20 and the second mold core 30 is uniform and reliable, and the damage of the secondary ejection mold to the molded parts is reduced.
As shown in fig. 1 and 2, the mold-splitting ejector rod 50 further includes a limiting elastic element 53, the second ejection part 52 is a hinged inclined block, and the limiting elastic element 53 is connected between the first ejection part 51 and the hinged inclined block; the limiting elastic element 53 is a spring or elastic rubber, and when the hinged inclined block is accommodated in the second ejector rod channel 41, the limiting elastic element 53 is stressed and compressed, so that the die parting ejector rod 50 can move; when the hinged inclined block is positioned between the third mold core 40 and the second mold core 30, the limiting elastic element 53 is unfolded, so that the hinged inclined block is stopped against the second mold core 30 and can push the second mold core 30 to move; when the mold splitting ejector rod 50 retracts to enable the second mold core 30 to be contacted with the third mold core 40, the hinged inclined block compresses the limiting elastic element 53 under the action of the second ejector rod channel 41; the structure is convenient, and the die-splitting ejector rod 50 is simple in structure.
The above is the preferred embodiment of the present invention, and is not used to limit the protection scope of the present invention. It should be recognized that non-inventive changes and modifications to the disclosed embodiments, as understood by those skilled in the art, are intended to be included within the scope of the present invention.
