The problems encountered with the two-color plastic product 100 shown in fig. 7-11 are: if the first color injection is completed, it is assumed that the first color slider is retracted after the mold is opened. When the whole rear mold part rotates 180 degrees, the slide block needs to move forwards again to ensure the mold closing state when rotating to the second color position, and the surface and structure of a product can be seriously damaged when the slide block moves forwards in the mold closing process. The reason why the slider is to be moved forward to the injection molding position state at the second color is because if the slider is not moved forward in the injection molding position, the second color molding cannot be completed because the pressure is large at the time of injection molding the second color and the slider is in the retreated state. Therefore, when the first injection molding is finished, the sliding block is ensured not to retreat, so that the damage to the product caused by the forward movement of the sliding block in the second color process can be avoided, and the pressure of the injection molded second color product can be resisted to protect the first color product from damage.
As shown in fig. 9, the first color of the plastic product is indicated by the indication line a, and the second color of the plastic product is indicated by the indication line B.
The working principle of the double-shot injection mold with the backstop structure is as follows:
1. and (3) closing the mold and simultaneously injecting the product by the injection molding machine, and opening the mold under the action force of the machine table.
2. When the mold is opened, the first color blade remains stationary as it is fixed to the stationary mold part. When the rear mould part of the mould moves backwards, the first color shovel machine cannot pull the sliding block, so that the sliding block can be kept at the injection molding position and cannot retreat.
3. When the mold is opened, the entire rear mold portion is rotated 180 ° under the action of the injection molding machine, rotating the product just injection molded of the first color to the second color along with the slide.
4. The second mold closing operation is started, and when the slide block at the second color position contacts the inclined surface on the pulling block fixed on the second color shovel machine at the second color position, the pulling block starts to rotate around the rotating shaft. When the mold is continuously closed to a certain position, the two inclined planes are staggered and do not contact, and the pulling block is elastically reset under the action of a spring force, so that the pulling block is hung in the pulling block body on the sliding block body.
5. And finishing the second mold closing action, and working the injection molding machine to inject the second color product. Then the mould is opened for the second time, at this time, the block is pulled by the action of the pulling block, and the sliding block starts to move backwards.
6. The mold is completely opened, and when the product is completely ejected, the manipulator is taken out, and the action is repeatedly started.
Based on the structure, the working steps of the retaining structure of the application are as follows:
1) When a first color product is subjected to injection molding, after the mold is closed, the first color shovel 1 is respectively pressed on the sliding block body 2 and the pulling block body 3, and injection molding is started;
2) After injection molding is completed, the mold is opened, the whole rear mold part is rotated by 180 degrees, and the product after the first color injection molding is rotated to a second color injection molding part;
3) The second color mold closing starts to perform injection molding, the first inclined surface 51 is firstly contacted with the second inclined surface 31, the second color shovel 4 pushes the pulling block 5 to be pressed down along with the progress of the mold closing, the pulling block 5 is pushed to rotate a certain angle along the rotating shaft 7 along with the continuous increase of pressure, the first inclined surface 51 and the second inclined surface 31 relatively move, and when the mold closing reaches a certain position in the mold closing process, the first inclined surface 51 and the second inclined surface 31 are staggered;
4) The pulling block 5 is pressed into the first groove 35, the pulling block 5 rotates around the rotating shaft 7 to return to the original position under the action force of the spring 6, and at the moment, the third inclined surface 52 is attached to the fourth inclined surface 32, so that the pulling block 5 is hung in the sliding block body 2;
5) The second color mold assembly is completed, and the injection molding machine starts to inject the second color product;
6) When the die is opened, the pulling block 5 pulls the pulling block body 3 to move, and the pulling block body 3 is clamped with the sliding block body 2, so that the sliding block body 2 is driven to move, and the die stripping is completed.
The foregoing is merely a preferred embodiment of the invention, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the invention, which modifications would also be considered to be within the scope of the invention.
