Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically relating to a novel ejector plate structure for injection molds. Background Technology

[0002] After plastic products are molded, they need to be separated from the mold. Currently, the common method is to use an ejector plate to drive the ejector plate to eject the plastic products from the moving mold.

[0003] When using this demolding method, because the ejector plate needs to move relative to the moving mold, space must be left below the moving mold for the ejector plate to move relative to the moving mold. Therefore, as disclosed in publication (announcement) number CN223442719U, mold feet are required to elevate the moving mold. However, because a large portion of the moving mold is now suspended in the air, the moving mold needs to be thicker to ensure it can withstand the pressure during injection molding. The thicker moving mold and the necessary mold feet make the manufacturing cost of molds using this demolding method prohibitively high.

[0004] Therefore, this application proposes a new ejector plate structure for injection molds. Utility Model Content

[0005] The purpose of this invention is to provide a novel ejector plate structure for injection molds, in order to solve the technical problem that the current method of using an ejector plate to drive an ejector plate for demolding in injection molds results in the moving mold piece being lifted into the air.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel ejector plate structure for injection molds, comprising: a moving mold having an ejection through hole on one side; and an ejector plate disposed on the side of the moving mold with the ejection through hole and connected to one end of an ejector rod that passes through the ejection through hole, so that the ejector rod separates from the moving mold when the other end of the ejector rod is pushed toward the side of the moving mold with the ejection through hole.

[0007] Furthermore, the ejection through hole is located at the center of the moving mold.

[0008] Furthermore, the novel ejector plate structure for injection molds also includes: a pair of ejector auxiliary through holes, which are opened on the side of the moving mold where the ejector through holes are opened, and are symmetrical about the ejector through holes, so that the ejector plate can be connected to another pair of ejector rods through the ejector auxiliary through holes.

[0009] Furthermore, a lower limiting hole is formed on the opposite side of the moving mold where the ejection through hole is formed, and the lower limiting hole extends toward the side of the moving mold where the ejection through hole is formed; a upper limiting hole is formed at the bottom of the lower limiting hole, and the upper limiting hole penetrates the moving mold, so that one end of the ejection limiting rod passes through the lower limiting hole and the upper limiting hole and connects with the ejection plate, so that when the limiting protrusion at the other end of the ejection limiting rod and the step at the transition between the upper limiting hole and the lower limiting hole abut against each other, the ejection plate is limited.

[0010] Furthermore, a connecting screw hole is opened on the end face of the other end of the ejector rod.

[0011] Furthermore, the side of the moving mold with the lower limiting hole is set on the base plate, and the base plate has holes that are compatible with the ejection through hole, the ejection secondary through hole, and the lower limiting hole.

[0012] Furthermore, the novel ejector plate structure for injection molds further includes a fixed mold, which is adapted to the moving mold to cover the moving mold.

[0013] Furthermore, the side of the fixed mold facing away from the moving mold is disposed on the panel.

[0014] The beneficial effects of this utility model are as follows: This utility model aims to solve the technical problem that the current method of using an ejector plate to drive an ejector plate for demolding in injection molds results in large sections of the moving mold being lifted into the air. This novel ejector plate structure for injection molds addresses this problem by creating an ejection through-hole in the moving mold. An ejector rod that can move up and down within this through-hole, after connecting with the ejector plate, can drive the ejector plate, achieving demolding of the plastic product when the ejector plate separates from the moving mold. This eliminates the need for mold feet, and the area of ​​the ejection through-hole is only a small proportion of the moving mold's area, preventing large sections of the moving mold from being lifted into the air and eliminating the need for additional thickness. By eliminating the need for mold feet and additional thickness, the manufacturing cost of this novel ejector plate structure for injection molds is reduced. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments implemented by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Example like Figure 1 As shown, this utility model provides a novel ejector plate structure for injection molds, including: a moving mold 100, one side of which has an ejection through hole 110; combined with Figure 2 An ejector plate 200 is disposed on one side of the moving mold 100 where the ejector through hole 110 is opened, and is connected to one end of the ejector rod 300 that passes through the ejector through hole 110, so that it separates from the moving mold 100 when the other end of the ejector rod 300 is pushed toward the side of the moving mold 100 where the ejector through hole 110 is opened.

[0019] This novel ejector plate structure for injection molds utilizes an ejection through-hole 110 on the moving mold 100. An ejector rod 300, which can move up and down within this through-hole 110, connects to the ejector plate 200, enabling the ejector plate 200 to move and separate from the moving mold 100, thus demolding the plastic product. This eliminates the need for mold feet. Furthermore, the moving mold 100 only requires the ejection through-hole 110, whose area is a very small proportion of the total area of ​​the moving mold 100, preventing any large sections of the moving mold 100 from becoming hollow and eliminating the need for additional thickness. By eliminating the need for mold feet and additional thickness, the manufacturing cost of this novel ejector plate structure for injection molds is reduced.

[0020] Preferred, such as Figure 1 As shown, the ejection through hole 110 can be formed at the center of the moving mold 100.

[0021] like Figure 1 As shown, the novel ejector plate structure of this injection mold may further include: a pair of ejector auxiliary through holes 120, which are formed on the side of the moving mold 100 where the ejector through hole 110 is formed, and are symmetrical about the ejector through hole 110, so that the ejector plate 200 is connected to another pair of ejector rods 300 through the ejector auxiliary through holes 120. When three ejector rods 300 are used to drive the ejector plate 200, the ejection of the ejector plate 200 can be more stable.

[0022] like Figure 3As shown, a lower limiting hole 130 can be opened on the opposite side of the moving mold 100 where the ejection through hole 110 is opened. The lower limiting hole 130 extends toward the side of the moving mold 100 where the ejection through hole 110 is opened. A lower limiting hole 140 is opened at the bottom of the lower limiting hole 130 and the upper limiting hole 140 penetrates the moving mold 100 so that one end of the ejection limiting rod 400 passes through the lower limiting hole 130 and the upper limiting hole 140 and connects with the ejection plate 200. When the limiting protrusion 410 at the other end of the ejection limiting rod 400 and the step at the transition between the upper limiting hole 140 and the lower limiting hole 130 abuts, the ejection plate 200 is limited to prevent the ejection plate 200 from being accidentally ejected too much.

[0023] In at least one embodiment, the other end face of the ejector rod 300 may have a connecting screw hole for connecting to the injection molding machine ejector rod.

[0024] like Figure 2 As shown, the side of the moving mold 100 with the limiting lower hole 130 can be set on the base plate 500, and the base plate 500 has holes that are compatible with the ejection through hole 110, the ejection secondary through hole 120, and the limiting lower hole 130.

[0025] like Figure 2 As shown, the novel ejector plate structure of this injection mold may further include: a fixed mold 600, which is adapted to the moving mold 100 to cover the moving mold 100.

[0026] like Figure 2 As shown, the side of the fixed mold 600 facing away from the moving mold 100 can be disposed on the panel 700.

[0027] In summary, this novel ejector plate structure for injection molds, by creating an ejection through-hole 110 on the moving mold 100, allows the ejector rod 300, which can move up and down within the ejection through-hole 110, to drive the ejector plate 200 after connection with it. This enables the demolding of the plastic product when the ejector plate 200 separates from the moving mold 100, eliminating the need for mold feet. Furthermore, the moving mold 100 only requires the ejection through-hole 110, and the area of ​​the ejection through-hole 110 is a very small proportion of the total area of ​​the moving mold 100, preventing any large sections of the moving mold 100 from becoming hollow and eliminating the need for additional thickness. By eliminating the need for mold feet and additional thickness, the manufacturing cost of this novel ejector plate structure for injection molds is reduced.
