a fixed die seat plate 11, wherein a feed port is arranged on one side of the fixed die seat plate 11, and the fixed die seat plate 11 is a fixed end;
the fixed die core 17, the fixed die core 17 is fixedly connected with the fixed die seat plate 11, and a core 21 is arranged at the bottom end of the fixed die core 17;
the movable mold core 18, the movable mold core 18 is a movable end, the top end of the movable mold core 18 is provided with a cavity 22, when the fixed mold core 17 and the movable mold core 18 are mutually adhered, a closed molding area is formed between the mold core 21 and the cavity 22, a raised clamping strip 25 is arranged in the molding area, and a feed port of the fixed mold seat plate 11 is communicated with the molding area;
the oblique top 24, the oblique top 24 and the fixed die core 17 are in sliding connection, one end of the oblique top 24 stretches into a forming area to form a forming end, the forming end is used for forming a convex clamping strip 25, a discharging mechanism is arranged in the oblique top 24 and comprises a pushing part, and the pushing part is slidably arranged at one end of the oblique top 24, which participates in forming.
It will be appreciated that the upper cover formed in the forming area is the cover 23, and the clip 25 is a protruding portion of the cover 23, so that the forming end of the inclined top 24 forms the protruding portion of the cover 23. The feeding gate of the fixed die seat plate 11 is a gate through which the external injection molding machine injects molten plastic into the molding region to mold the cover 23.
The hot runner 14 is connected with an external injection molding machine, and the hot runner 14 is communicated with a feed port of the fixed die seat plate 11;
the push plate seat plate 12 is slidably arranged between the fixed die seat plate 11 and the fixed die core 17, and the push plate seat plate 12 is fixedly connected with the inclined top 24;
the telescopic device 13 is connected with an external injection molding machine, the telescopic device 13 is driven to stretch and retract by the external injection molding machine, and the telescopic device 13 is fixedly connected with the push plate seat plate 12;
the movable die base plate 19, the movable die base plate 19 is connected with an external injection molding machine, the movable die core 18 is fixedly connected with the movable die base plate 19, and a driving mechanism of the external injection molding machine drives the movable die base plate 19 to move.
It can be understood that the push plate seat plate 12 is only used for sliding to drive the inclined top 24 to move, the formed cover 23 can be pulled out by moving the inclined top 24, the telescopic device 13 is a component for driving the push plate seat plate 12 to slide, and the telescopic device 13 can be a telescopic push rod which is separately connected with the push plate seat plate 12, such as a hydraulic cylinder, or can be a driving mechanism on an external injection molding machine, and can drive the push plate seat plate 12 to move. The movable die seat plate 19 is a movable end and is connected with a driving mechanism on an external injection molding machine, and the driving mechanism on the external injection molding machine drives the movable die seat plate 19 to move so as to control the fit and the separation of the brake die core 18 and the fixed die core 17.
A pushing block cavity 31 is formed in the inclined top 24, and a pushing part is arranged in the pushing block cavity 31 in a sliding manner;
the pushing part comprises a pushing block 33, the pushing block 33 is in sliding connection with the lower wall of the pushing block cavity 31, a spring 32 is fixedly arranged on one side wall of the pushing block cavity 31, and one end of the spring 32 is fixedly connected with the pushing block 33.
The sliding direction of the push block 33 is in the same horizontal direction as the clip strip 25.
It will be appreciated that the angled roof 24 is a component that pushes out the molded cover 23, and normally when the angled roof 24 pushes out the molded cover 23, the clip 25 will be blocked in the angled roof 24 due to the protrusion, so that it is difficult to release the mold, so that the push block 33 needs to slide out of the angled roof 24 to push out the clip 25 out of the angled roof 24, so as to facilitate release the mold, and the spring 32 provides the pushing force of the push block 33. The spring 32 may be a spring element, a rubber block, or the like, and may have a biasing force.
The pushing part further comprises a connecting rope 34, the bottom end of the connecting rope 34 is fixedly arranged with the pushing block 33, and the other end of the connecting rope 34 penetrates through the inclined top 24 and the push plate seat plate 12 and extends to the upper side of the push plate seat plate 12.
The pushing part further comprises a magnet 35 and a magnet 36, the magnet 36 is fixedly connected with the connecting rope 34, the magnet 35 is fixedly arranged on the lower end face of the push plate seat board 12, and the magnet 35 is magnetically connected with the magnet 36.
The magnetic attraction force of the magnet 35 and the magnet 36 is greater than the urging force of the spring 32.
It will be appreciated that the connecting rope 34 is used for connecting the push block 33, the magnet 35 and the magnet 36, and since the magnet 35 and the magnet 36 are connected by magnetic attraction force, when the tension force of the connecting rope 34 is larger than the magnetic attraction force between the magnet 35 and the magnet 36, the magnet 35 and the magnet 36 can be separated, so that the push block 33 is pushed out by the thrust of the spring 32, when the connecting rope 34 is not pulled, the magnet 35 and the magnet 36 can be attracted by the magnetic attraction force to tighten the spring 32 by tightening the connecting rope 34, so that the movement of the push block 33 is more flexible and the movement track of the whole injection mold is fitted.
Working principle: in the initial state, the feeding end of the external injection molding machine is communicated with the hot runner 14, the driving mechanism is fixed with the movable die base plate 19, the magnet 35 and the magnet 36 are in an adsorption state, the connecting rope 34 is stressed tightly, and the spring 32 is stressed and compressed. The movable die seat plate 19 is pushed by the driving mechanism so as to enable the fixed die core 17 and the movable die core 18 to be in a bonding state, at the moment, the forming area is in a closed state through bonding of the core 21 and the cavity 22, molten plastic is injected by an external injection molding machine, sequentially passes through the fixed die seat plate 11, the push plate seat plate 12 and the fixed die core 17 through the hot runner 14 so as to enter the forming area, and then the forming of the cover body 23 is completed through solidification.
When the cover 23 needs to be pushed out from the molding area after molding, the movable die seat plate 19 is pulled away from the fixed die core 17 by the driving mechanism, so that the movable die core 18 is driven to be separated from the fixed die core 17, the cover 23 is tightly attached to the core 21 due to the tightening force, the expansion device 13 needs to be started to be extended, the push plate seat plate 12 is driven to move towards one side of the fixed die core 17, the oblique top 24 synchronously moves to push the molded cover 23 away from the fixed die core 17 through the movement of the push plate seat plate 12, meanwhile, the magnet 36 is separated from the magnetic block 35 due to the movement of the oblique top 24 and the connection of the connecting rope 34, at the moment, the elastic force of the spring 32 is released due to the fact that the connecting rope 34 is not pulled, so that the push block 33 is pushed to slide, the clamping strip 25 clamped in the oblique top 24 is pushed out, and the clamping strip 25 naturally falls down to complete demolding after being pushed out.
When the tilt head 24 moves back up again to the original state, the magnet 36 attracts the magnet block 35, thereby pulling the push block 33 back into the push block cavity 31 by pulling the connecting cord 34.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
