Because the utility model discloses a movable mould mold insert cup joints the upper portion at the bearing frame through the bearing activity, and when the ascending ejecting product of thimble, the product is fixed motionless, utilizes the skewed tooth of product self to drive the movable mould mold insert and rotates, and the bearing of the peripheral parcel of movable mould mold insert makes the rotation that the movable mould mold insert can relax, lets the smooth drawing of patterns of product.

Description

Self-rotating helical tooth demolding mold

Technical Field

The utility model relates to an injection mold especially relates to a self-rotating skewed tooth drawing of patterns mould.

Background

The plastic injection mold is a tool for producing plastic products and has wide application. In the injection molding of plastic products, because some plastic products are provided with helical teeth and the like, a structure capable of completely extracting the plastic products is required, but the production of the mold capable of quickly and conveniently extracting the plastic products has certain difficulty, and the problem to be solved by the technical personnel in the field is always solved.

Disclosure of Invention

An object of the utility model is to provide an easy drawing of patterns from rotating skewed tooth drawing of patterns mould.

In order to achieve the above object, the technical solution of the present invention is:

the utility model relates to a self-rotating helical tooth demoulding mould, which comprises a panel, a water gap plate, a fixed mould plate, a movable mould plate, a base plate, square iron, a bottom plate, a top plate, a movable mould insert, a bearing seat and a thimble; the panel, the water gap plate and the fixed template are fixed together in sequence, the bottom surface of the fixed template is opposite to the top surface of the movable template, the base plate, the square iron and the bottom plate are fixed together in sequence, and the top plate is arranged between the base plate and the bottom plate; the top of the movable mold insert is provided with an annular groove serving as a cavity, the side wall of the annular groove is provided with a plurality of inclined grooves serving as product inclined teeth, the movable mold insert is movably sleeved on the upper part of a bearing seat through a bearing, and the lower part of the bearing seat is fixedly arranged on a movable template; the lower end of the ejector pin is fixed on the top plate, and the upper end of the ejector pin penetrates through the base plate and the bearing seat and then extends into the cavity.

The lower part clearance of movable mould mold insert cup joints on the bearing frame, and the outer wall fixed cover of movable mould mold insert is put at the downthehole of bearing, and the outer wall fixed cover of bearing is put in the movable mould board.

After the scheme of the above, because the utility model discloses having movable mould mold insert, bearing frame, the movable mould mold insert cup joints on the upper portion of bearing frame through the bearing activity, and when the ejecting product of thimble upwards, the product is fixed motionless, utilizes the skewed tooth of product self to drive the movable mould mold insert and rotates, and the bearing of the peripheral parcel of movable mould mold insert makes the rotation that the movable mould mold insert can relax, lets the smooth drawing of patterns of product.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 1-5, the utility model relates to a self-rotating helical tooth demolding mold, which comprises a panel 1, a nozzle plate 2, a fixed mold plate 3, a movable mold plate 4, a backing plate 5, square iron 6, a bottom plate 7, a top plate 8, a movable mold insert 9, a bearing 10, a bearing seat 11 and a thimble 12.

The face plate 1, the nozzle plate 2 and the fixed template 3 are fixed together in sequence, the bottom surface of the fixed template is opposite to the top surface of the movable template, the movable template 4, the backing plate 5, the square iron 6 and the bottom plate 7 are fixed together in sequence, and the top plate 8 is arranged between the backing plate 5 and the bottom plate 7; the top of the movable mold insert 9 is provided with an annular groove 91 serving as a cavity, the side wall of the annular groove 91 is provided with a plurality of inclined grooves 92 serving as product inclined teeth 101 (shown in fig. 7), the movable mold insert 9 is movably sleeved on the upper part of a bearing seat 11 through a bearing 10, and the lower part of the bearing seat 11 is fixedly arranged on the movable mold plate 4; the lower end of the thimble 12 is fixed on the top plate 8, and the upper end of the thimble 12 passes through the cushion plate 5 and the bearing seat 11 and then extends into the cavity.

In this embodiment, the lower gap of the movable mold insert 9 is sleeved on the bearing seat 11, the outer wall of the movable mold insert 9 is fixedly sleeved in the hole of the bearing 10, the outer wall of the bearing 10 is fixedly sleeved in the movable mold plate 4,

the utility model discloses a theory of operation:

as shown in fig. 1, when the ejector pin 12 ejects the product 100 upward, the product 100 is fixed, the movable mold insert 9 is driven to rotate by the inclined teeth 101 (shown in fig. 6 and 7) of the product 100, and the bearing 10 wrapped around the movable mold insert 9 enables the movable mold insert 9 to rotate easily, so that the product can be demolded smoothly.
