Abstract
The utility model discloses an injection mould which sequentially comprises a stationary mould fixing plate, a stationary mould, a movable mould, a cavity, a push rod fixing plate and a movable mould fixing plate, wherein a push rod I, a push rod II and a reset rod are installed above the push rod fixing plate, and a slicer reset block and a push rod III internally provided with a runner are sequentially arranged above the cavity. A sprue slicer is arranged on one side, and a spring is connected below the slicer. The utility model provides the injection mould which solves the problem that the sprue is automatically cut off for the mould fed from the side sprue, so that a material cutting step is reduced, the work intensity of workers is alleviated, automatic injection is realized, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of injection molding.
Background technology
Most plastic products were produced and were all adopted injection machine mould moulding to make present stage.Some goods needs the mould of side gate charging when actual production, and existing mould cannot be realized the automatic cut-out of side gate, must increase a kind of material process of cutting, and is unfavorable for realizing automatic injection, has reduced production efficiency.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of injection molding, to solve, the mould of side gate charging is realized to the difficult problem that cast gate cuts off automatically simply, reduced and cut together material process, alleviate labor strength, realized automatic injection, improved production efficiency.
For achieving the above object, the technical solution of the utility model is as follows:
An injection molding, comprises quiet mould fixed head, quiet mould, dynamic model, die cavity, ejector pin retaining plate and dynamic mould fixing plate from top to bottom successively; Described ejector pin retaining plate top is provided with push rod one and push rod two, and the two ends of described push rod one connect respectively described ejector pin retaining plate and described quiet mould, and the two ends of described push rod two connect respectively described ejector pin retaining plate and described quiet mould fixed head; Described ejector pin retaining plate top is also provided with release link, it is characterized in that, described die cavity top be provided with successively cutting knife resetting block and in establish runner push rod three, one sides be provided with a cast gate cutting knife, this cutting knife below connects a spring.
Preferably, described cast gate cutting knife is connected in quiet mould below by a dynamic model mold insert, and in its junction, one straight pin is installed.
The utility model provides a kind of injection molding, has solved the mould of side gate charging is realized to the difficult problem that cast gate cuts off automatically, has reduced and has cut together material process, has alleviated labor strength, has realized automatic injection, has improved production efficiency.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of injection molding, comprises quiet mould fixed head 11, quiet mould 10, dynamic model 4, die cavity 7, ejector pin retaining plate 2 and dynamic mould fixing plate 1 from top to bottom successively; There are push rod 1 and push rod 2 13 in ejector pin retaining plate 2 tops, and the two ends of push rod 1 connect respectively ejector pin retaining plate 2 and quiet mould 10, and the two ends of push rod 2 13 connect respectively ejector pin retaining plate 2 and quiet mould fixed head 11; Ejector pin retaining plate 2 tops are also provided with release link 15; Die cavity 7 tops be provided with successively cutting knife resetting block 8 and in establish runner 12 push rod 39, one side be provided with a cast gate cutting knife 6, these cutting knife 6 belows connect a spring 5.
Wherein, cast gate cutting knife 6 is connected in quiet mould 10 belows by a dynamic model mold insert 14, and a straight pin 16 is installed in its junction.
Implementing procedure: 1, injection: molten plastic enters die cavity 7 by the cast gate between runner 12, cast gate cutting knife 6 and cutting knife resetting block 8, until end-of-fill; 2, gate cutting: goods are after die cavity 7 curing moldings, and cast gate cutting knife 6, cutting knife resetting block 8, push rod 9 advance under the effect of spring 5, and runner 12 is separated with goods; 3, die sinking: quiet mould 10 is separated with dynamic model 4, goods and runner 12 are trapped on dynamic model mold insert 14, until die sinking finishes; 4, goods depanning: goods eject dynamic model mold insert 14, removed or automatically fall; 5, matched moulds: cast gate cutting knife 6, spring 5 reset under the effect of push rod 9, cutting knife resetting block 8, until matched moulds finishes.
The utility model provides a kind of injection molding, has solved the mould of side gate charging is realized to the difficult problem that cast gate cuts off automatically, has reduced and has cut together material process, has alleviated labor strength, has realized automatic injection, has improved production efficiency.
To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.
