Detailed ways:

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figures 1-3, the utility model is an injection mold for a screwdriver head storage seat, which includes a movable mold seat plate 2, a cushion block 3, a backing plate 4, a movable mold plate 5, and an inclined slider connected sequentially via a guide column 1. Fixed plate 6, fixed formwork 7 and fixed formwork seat plate 8, the middle part of described fixed formwork seat plate 8 is provided with positioning ring 9, and the below of described positioning ring 9 is provided with the sprue that communicates with the sprue on the fixed formwork 7 Bushing 10; the oblique slider 11 is fixed on the oblique slider fixing plate 6, and the oblique slider 11 is provided with a through hole whose inner side wall is compatible with the outer surface of the screwdriver bit receiving seat 24, and the through hole A first core 12 for injection molding to form a first groove is provided inside, and the first groove is used to accommodate the screwdriver handle; the outer side of the first core 12 is provided for injection molding to form several rings The second core 13 of the second groove of the distribution, the second groove is used to accommodate the screwdriver bit; the first core 12, the second core 13, the inclined slider 11 and the fixed template 7 surround The formed cavity is the mold cavity; a demoulding mechanism is also arranged between the fixed template 7 and the movable mold seat plate 2.

In this embodiment, the demoulding mechanism includes a push plate 14 and a push-out fixed plate 15 located between the backing plate 4 and the movable mold seat plate 2, and a push rod 16 and a reset rod 17 are pierced on the push-out fixed plate 15 And pull rod 18, described push rod 16 passes through first mold core 12, and the top surface of push rod 16 is flush with the top surface of first mold core 12; The bottom surface of the backing plate 4 and the push-out fixing plate 15 are provided with a reset spring 25 sleeved on the outside of the reset rod 17; the pull rod 18 passes through the inclined slider 11 and extends into the runner. When the mold is demoulded, the mold is divided from the parting surface, that is, the movable mold seat plate, cushion block, backing plate, movable mold plate and inclined slider fixed plate move away from the fixed platen, and stop moving when the required mold opening stroke is reached. After stopping the movement, the push rod, push plate, reset rod, and push-out fixing plate move synchronously towards the direction of the fixed template, and the push rod pushes out the finished product to realize demoulding. After the demoulding is completed, the reset lever resets the demoulding mechanism under the action of the return spring, and finally the whole resets to prepare for the next injection molding.

In this embodiment, the movable template 5 and the fixed plate of the inclined slider 6 are respectively provided with guide sleeves 19 to facilitate the sliding of the guide post 1 .

In this embodiment, the push plate 14 and the push-out fixing plate 15 are fixedly connected by bolts 20 .

In this embodiment, the number of the cavity is two.

In this embodiment, garbage nails 23 are provided between the movable mold base plate 2 and the push plate 14, so that there is a gap between the movable mold base plate 2 and the push plate 14, so as to prevent the movable mold base plate 2 from contacting the push plate 14. There is rubbish between the plates 14, causing the demoulding mechanism to fail to reset, and to form plastic parts.

In this embodiment, a first positioning pin 21 is provided between the fixed mold base plate 8 and the fixed template 7; , the backing plate 4, the movable template 5 and the fixed plate 6 of the inclined slider are provided with a second positioning pin 22.

In this embodiment, the positioning ring 9 is locked on the base plate of the fixed mold through screws.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
