Description

Single top plate secondary ejection mechanism for automotive exterior parts mold

technical field

The utility model relates to a secondary ejection mechanism for a single top plate of an automobile exterior decoration mold, which belongs to the field of injection molds.

Background technique

Using injection molds to produce plastic products, such as automotive exterior parts, according to the product shape and structure analysis, when the product is molded and demolded, due to the complex structural features of the product, a certain structure on the product is still firmly in place when it is ejected for the first time The top block of the ejection mechanism may be wrapped on the thimble, and cannot come off automatically, and it needs to be pushed again to fall off. In the traditional mold, a top plate is added to the ejection mechanism to form three top plates to realize the second ejection. The disadvantages are that the ejection stroke is long, the movement range is large, and it is unstable, and the investment cost of the mold is increased by adding a top plate.

Contents of the invention

The purpose of this utility model is to overcome the disadvantages of the prior art, and provide a single top plate secondary ejection mechanism for automobile exterior trim molds with a simple structure, stable and reliable action, which adopts a single ejector block structure to realize the second ejection of the ejector pin. .

The technical scheme of the secondary ejection mechanism of the single top plate of the automobile exterior decoration part mold of the present utility model is: including the fixed mold double plate and the movable mold double plate, the runner frame is arranged under the fixed mold double plate, the fixed template is connected under the flow channel frame, The mold feet are installed on the movable mold doubler plate, and the movable template is installed on the mold feet. The gap between the movable template and the fixed template forms a mold cavity, and the injection molding product in the mold cavity is characterized in that a single needle is set between the mold feet. The single ejector pin and the thimble are connected to the single needle board, and the single ejector block is installed on the single ejector pin, and the single ejector block and the ejector pin are in contact with the product. The bottom of the single ejector rod passes through the single top plate, and is set The fixed seat, the shaft pin is set in the fixed seat, the rocker is connected to the shaft pin, there is a support block under the rocker, the bottom of the single ejector rod is in contact with one end of the rocker, the pressure rod is connected to the bottom surface of the movable template, and the through hole is set in the single top plate. hole, and the pressing rod is corresponding to the other end of the seesaw through the through hole.

The utility model discloses a secondary ejection mechanism for a single top plate of an automobile exterior decoration mold. When demoulding, the dynamic mold plate is driven by the power of the injection molding machine to separate from the fixed mold plate. When the mold is opened, the push rod on the injection molding machine pushes the On the single top plate, the single top plate is pushed up, and the single top plate drives the single ejector pin and other thimbles to jack up the product to realize the first ejection. However, due to the complex structure of the product, the product will not It is still firmly on the thimble, so when the single top plate continues to push up, the pressure rod contacts the seesaw through the through hole, pressing down one end of the seesaw, and the other end of the seesaw is tilted through the pivot pin and the support block, and the single top is lifted. The rod is ejected, so that the single ejector block on the single ejector rod lifts the product from the thimble to realize the second ejection, the product automatically falls off from the single ejector block, and the demoulding is completed. This scheme adopts a single top plate structure to realize the secondary ejection of single ejector rod, which not only reduces the number of top plates and saves costs, but also realizes secondary ejection through the seesaw. The structure is simple, the action is stable and reliable, ensuring continuous production of molds and improving production efficiency .

The utility model relates to the secondary ejection mechanism of the single top plate of the automobile exterior decoration mold. A return spring is arranged between the single ejector rod and the single top plate, and is fixed by a collar. The return spring assists the reset of the single ejector rod. The movable mold doubler plate is provided with an avoidance groove, and the fixed seat and the seesaw are located in the avoidance groove. With the avoidance groove, it is convenient for loading and unloading of the seesaw. The mold foot is provided with observation holes, and there are multiple observation holes, through which the working condition of the single ejector rod can be checked in multiple directions, which is beneficial to maintenance.

Detailed ways

The utility model relates to a secondary ejection mechanism for a single top plate of an automobile exterior decoration mold, as shown in Figure 1 and Figure 2, comprising a fixed mold double plate 1 and a movable mold double plate 2, and a flow channel is arranged under the fixed mold double plate Frame 3, the fixed template 4 is connected under the runner frame, the mold foot 5 is installed on the movable mold doubler plate, the movable template 6 is installed on the mold foot, the gap between the movable template and the fixed template forms a mold cavity, and the injection molded product 7 in the mold cavity , a single needle plate 8 is arranged between the mold feet 5, a single ejector pin 9 and a thimble 14 are connected on the single needle plate, a single ejector block 10 is installed on the single ejector bar, and the single ejector block 10 and the ejector pin 14 are in phase with the product 7 contact, the bottom of the single ejector rod 9 passes through the single top plate 8, and a fixed seat 11 is set on the bottom surface of the single top plate 8, and a shaft pin 12 is arranged in the fixed seat 11, and a seesaw 13 is connected on the shaft pin, and there is a support under the seesaw 13. Block 15, the bottom of single ejector rod 9 is in contact with one end of seesaw 13, and pressure bar 16 is connected on the bottom surface of movable formwork 6, and through hole 17 is set in single top plate 8, and press bar 16 passes through hole 17 and the other end of seesaw 13 Correspondingly. When demolding, the power of the injection molding machine drives the mold movable template 6 to separate from the fixed template 4. The ejector rod 9 and other ejector pins 14 together lift up the product to realize the first ejection, but due to the complex structural features of the product, the product 7 is still firmly on the ejector pin during the first ejection, so the single ejector plate 8 continues In the upper jacking, the pressing rod 16 contacts the seesaw 13 through the through hole 17, one end of the seesaw is pressed down, and the other end of the seesaw 13 is tilted up through the shaft pin 12 and the support block 15, and the single ejector rod 9 is pushed out.
