Description

Demoulding device

Technical Field

The embodiment of the disclosure relates to the technical field of injection molds, in particular to a demolding device.

Background

Existing plastic parts are typically injection molded using an injection mold. In order to ensure smooth transition of each part, the associated part is generally integrally formed, i.e. formed in one piece. While more and more plastic parts have inverted snap structures, such as the one shown in fig. 1. At the time of demolding, if the lifter is moved in the horizontal direction (in a direction away from the product) according to the conventional method, the lifter cannot be withdrawn. And may damage the contact surface of the product with the pitched roof.

The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Fig. 1 shows a schematic structural view of some embodiments of the demolding device of the present disclosure. As shown in fig. 1, the demolding device may include a mold core 11, a lifter 12, a lifter seat 13, and a guide block 14. The side wall of the mold core 11 is provided with a containing hole. The first end of the inclined top 12 can be inserted into a receiving hole of the mold core 11, so that together with the mold core 11 a mold surface adapted to the product can be formed. Meanwhile, the second end of the lifter 12 is connected with the first end of the lifter base 13. In addition, the first end of the slanted ejecting base 13 is provided with a slanted guide rail at the junction. And a second end of the slanted ejecting seat 13 is connected to an ejector plate (not shown in fig. 1). In addition, a guide block 14 is sleeved on the inclined top seat 13. The guide block 14 can restrict the movement of the slanted ejecting seat 13 in the horizontal direction. That is, the slanted ejecting base 13 can move up and down in the vertical direction under the restriction of the guide block 14.

As can be seen from fig. 1, the first end of the slanted ejecting part 12 leaks out of the surface of the receiving hole, and can form a complete mold surface with the mold core 11, so as to mold a product with a desired shape. Here, an upper end surface of the product is formed with an inverted slope, and a protrusion is formed at a position of the side wall corresponding to the sloped top. That is, the end surface of the first end of the lifter 12 (and the upper end surface of the mold core 11) is a slope. Meanwhile, the first end side of the inclined top 12 is provided with a groove corresponding to the protrusion of the product.

As can be seen from fig. 2, for a product of this configuration, the slanted top 12 cannot be withdrawn if the slanted top 12 is moved in a horizontal direction away from the product, i.e. in the direction of the dashed arrow shown in fig. 2. In addition, during the mold opening process, the inclined top 12 can damage the contact surface of the product, thereby affecting the product quality. Here, the inclined direction of the inclined guide rail corresponds to the inclined direction of the (inverted) inclined surface of the product. That is, as shown in fig. 2, if the slope of the product is inverted inward (toward the inside of the product), the inclined rail is also inclined toward the inside of the product. Thus, during the upward movement of the ejector plate driving the inclined ejector base 13, the inclined ejector 12 moves upward. At the same time, the lifter 12 is moved in a direction away from the product along the inclined rails (solid arrows shown in fig. 2) to complete the demolding. I.e. the lifter ejects the product from the mold core and separates it from the product. Therefore, smooth demoulding of the product can be realized, damage to the product is reduced or avoided, and the yield of the product is improved.

In some embodiments, the upper end surface of the projection on the side wall of the product is also beveled. As shown in fig. 2, the inclined direction of the inclined surface corresponds to the inclined direction of the (inverted) inclined surface of the product. And the inclination angle of the inclined plane is larger than that of the product. In this case, in order to enable the demolding of the product, the inclination angle of the inclined rail may be located between the inclination angles of the two inclined surfaces. The angle of inclination here generally refers to an acute angle relative to the horizontal. For example, in fig. 2, the inclination angle of the upper end face (inclined face) of the product is 24.4 °; the inclination angle of the upper end surface (inclined surface) of the protrusion is 30.0 degrees. At this time, the inclination angle of the inclined rail was 25.0 °. Thus, the lifter 12 does not damage the upper end surface of the product nor the protrusion of the side wall of the product during the demolding.

It will be appreciated that, in order to ensure smooth demoulding of the product, the projection dimension of the inclined rail in the horizontal direction is at least greater than the projection dimension of the (product side wall) projection in the horizontal direction. That is, the movable distance of the slanted ejecting part in the horizontal direction along the slanted guide rail is larger than the projected dimension of the protrusion in the horizontal direction. Thus, when the product is demolded, the separation of the lifter from the product can be achieved as long as the projections of the side wall of the product are completely removed from the recesses of the first end side of the lifter 12.

In addition, since one of the main functions of the lifter 12 is to eject the injection-molded product from the mold core 11, the mold core 11 is further provided with a stopper at the position of the receiving hole in order to prevent the lifter 12 from moving downward during the production process. The limiting block can be used for limiting the downward movement of the inclined top in the vertical direction. As can be seen from the dashed circle in fig. 2, the stopper a may be a boss structure formed by the mold core 11 at a fixed position corresponding to the inclined top 12.

It should be noted that the connection manner between the slanted ejecting part 12 and the slanted ejecting seat 13, and the specific structure of the slanted guide rail are not limited in this embodiment. As an example, both sides of the second end of the lifter may be provided with positioning parts. As can be seen from fig. 2 and 3, the positioning member may be located in the sliding groove of the inclined rail. Therefore, when the inclined top moves upwards, the positioning component can drive the inclined top to move along the sliding groove of the inclined guide rail. The positioning part can be a convex structure formed by the second end of the inclined top. Alternatively, as shown in fig. 1, the positioning member 15 may be a pin penetrating the lifter 12.

In some embodiments, the second end of the pitched roof may also be beveled. The inclined plane is matched with the inclined guide rail. When the die is opened, the inclined top seat provides upward acting force to the inclined top through the inclined plane at the joint of the inclined top seat and the inclined guide rail. Further, at least one groove (or protrusion) may be formed on the inclined rail. At this time, at least one protrusion (or groove) matched with the inclined guide rail can be formed on the inclined surface of the second end of the inclined top.

It will be appreciated that the guide block 14 may be mounted at any location on the slanted ejecting base. For example, may be determined based on the actual device configuration at the site. For another example, as shown in fig. 1, the guide block 14 may be located at the junction of the first end of the slanted ejecting seat 13 and the second end of the slanted ejecting 12. In this way, the guide block 14 not only can limit the lifter base 13, but also can limit the second end of the lifter 12 in the inclined rail to prevent the second end from sliding out of the inclined rail.

Further, the product in the embodiments of the present disclosure may be the structure shown in fig. 2. Namely, the upper end surface of the product is provided with an inclined surface which is turned back inwards. And a bulge is formed on the inner side wall of the product at a position corresponding to the inclined top. In some application scenarios, the upper end face of the product may be formed with a slope that is inverted outward. And a bulge is formed at the position of the outer side wall of the product corresponding to the inclined top.
