Description

Technical Field

[0001] This utility model relates to the field of toy and figurine production, and in particular to a mold forming and ejection mechanism for toy and figurine production. Background Technology

[0002] Toy figure injection molding refers to the process of manufacturing toy figures through injection molding. Injection molding is a process in which molten plastic is poured into a mold and then cooled to form the desired shape. Specifically, the injection molding process includes the following key steps: filling, holding pressure, cooling, and demolding.

[0003] During the demolding process of toy figures, the separation of the mold from the toy figure is difficult due to the large contact area between the head and body of the toy figure and the mold, which can easily damage the toy figure. Utility Model Content

[0004] To overcome the shortcomings of large contact areas between the head and body of toy figures and the mold, difficulty in separating the mold from the toy figures, and easy damage to the toy figures, this utility model provides a mold forming and ejection mechanism for toy figure production.

[0005] Technical solution: A mold forming and ejection mechanism for toy figure production, comprising a lower mold, an upper mold, a support plate, ejector rods, a top plate, and an ejector column; both the lower mold and the upper mold are provided with several air ducts; the lower mold is provided with the upper mold; the upper mold is provided with an injection port; the lower mold is provided with a support plate; several ejector rods are fixedly connected to the support plate; the top plate and the ejector column are fixedly connected to the support plate; it also includes a cylinder and an arc plate; the lower mold is provided with a cylinder; the lower mold is provided with an arc plate.

[0006] To further explain, the air ducts on the lower mold and the upper mold correspond and are connected.

[0007] To further explain, both the lower and upper molds have several grooves, and all the ejector pins are aligned with the corresponding grooves.

[0008] To further explain, all the grooves have rounded corners.

[0009] To further explain, the groove on the upper mold is smaller than the groove on the lower mold.

[0010] To further explain, there is a gap between the top plate and the arc plate, and a gap between the top column and the cylinder.

[0011] To further explain, it also includes connecting pipes; all the push rods are hollow inside, and all the push rods have air holes; the support plate is connected to the connecting pipes, and the connecting pipes are connected to all the push rods.

[0012] The beneficial effects of this utility model are: by setting the air ducts on the lower mold and the upper mold to be aligned and connected, the air blown out of the air duct on the lower mold collides with the air blown out of the air duct on the upper mold, so that the air can quickly diffuse between the lower mold and the upper mold, thereby improving the cooling efficiency of the lower mold and the upper mold.

[0013] This invention uses a cylinder instead of a top pillar to contact the head of the toy figure, increasing the contact area with the head. It also uses an arc plate instead of a top plate to contact the body of the toy figure, increasing the contact area with the body and facilitating the separation of the toy figure from the lower mold.

[0014] This invention establishes a gap between the top plate and the arc plate, and a gap between the top column and the cylinder. After the ejector rod pushes the ejector ear, the gap between the top plate and the arc plate decreases, and the gap between the top column and the cylinder decreases. After the ejector ear loses contact with the lower mold, the ejector ear causes the edge of the toy figure to separate from the lower mold, reducing the contact area between the toy figure and the lower mold and facilitating the demolding of the toy figure.

[0015] This invention delivers air into the connecting pipe by activating an external air source. The air vent is no longer blocked by the lower mold, and the air is ejected from the air vent. The air is sprayed between the lower mold and the toy figure, which accelerates the cooling of the toy figure and facilitates demolding. Attached Figure Description

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0023] Example: A mold forming ejection mechanism for toy figure production, such as... Figures 1-5 As shown, it includes a lower mold 1, an upper mold 2, a support plate 3, ejector pins 4, a top plate 5, and ejector columns 6; both the lower mold 1 and the upper mold 2 are provided with several air ducts 101; the lower mold 1 is provided with the upper mold 2; the upper mold 2 is provided with an injection port; the lower mold 1 is provided with a support plate 3; several ejector pins 4 are fixedly connected to the support plate 3; the top plate 5 and ejector columns 6 are fixedly connected to the support plate 3;

[0024] It also includes a cylinder 7 and an arc plate 8; the lower mold 1 is provided with a cylinder 7; the lower mold 1 is provided with an arc plate 8.

[0025] The air ducts 101 on the lower mold 1 and the upper mold 2 correspond to and are connected.

[0026] Both the lower mold 1 and the upper mold 2 have several grooves 102, and all the ejector pins 4 are aligned with the corresponding grooves 102.

[0027] All grooves 102 have rounded corners to reduce the contact area between the ejector ears and the lower mold 1 and the upper mold 2, which facilitates the demolding of the toy figure.

[0028] The groove 102 on the upper mold 2 is smaller than the groove 102 on the lower mold 1, which facilitates the removal of the toy figure from the upper mold 2.

[0029] There is a gap between the top plate 5 and the arc plate 8, and there is a gap between the top column 6 and the cylindrical column 7.

[0030] It also includes a connecting pipe 9; all the push rods 4 are hollow inside, and all the push rods 4 have air holes 41; the supporting plate 3 is connected to the connecting pipe 9, and the connecting pipe 9 is connected to all the push rods 4.

[0031] The workflow of this utility model is as follows:

[0032] The upper mold 2 is shallower than the lower mold 1, which makes it easier to separate the toy figure from the upper mold 2.

[0033] Before using this utility model, it needs to be installed on the injection molding device. The injection port of the upper mold 2 is connected to the injection port of the injection molding device. The injection molding device controls the opening and closing of the lower mold 1 and the upper mold 2. The injection molding device provides the lifting power for the support plate 3, and the production of toy figures begins.

[0034] The injection molding device controls the lower mold 1 and upper mold 2 to close the mold, as follows: Figure 1As shown, the injection molding device delivers the injection material to the injection port on the upper mold 2. The injection material flows between the lower mold 1 and the upper mold 2. The injection material forms an ejector ear at the groove 102 to perform injection molding of the toy figure. After the delivery of the injection material is completed, the injection material forms a specified shape in the lower mold 1 and the upper mold 2. After the toy figure is held under pressure.

[0035] The injection molding device controls the lower mold 1 and the upper mold 2 to open the mold, and the toy figure begins to separate from the upper mold 2. At the same time, the external air source is activated to cool the lower mold 1 and the upper mold 2. When cooling the lower mold 1 and the upper mold 2, the air blowing structure connected to the external air source needs to be allowed to enter between the lower mold 1 and the upper mold 2 after the lower mold 1 and the upper mold 2 have completed opening. The cooling efficiency is low, which affects the efficiency of toy figure production.

[0036] Before the injection molding of the toy figure, an external air source is connected to the air duct 101 via a pipe. By setting the air ducts 101 on the lower mold 1 and the upper mold 2 to be aligned and connected, the external air source is activated to supply air into the air duct 101 to cool the lower mold 1 and the upper mold 2. At this time, the lower mold 1 and the upper mold 2 are like... Figure 2 In the state shown, the air blown out of the upper air duct 101 of the lower mold 1 collides with the air blown out of the upper air duct 101 of the upper mold 2, causing the air to spread rapidly between the lower mold 1 and the upper mold 2, thereby improving the cooling efficiency of the lower mold 1 and the upper mold 2.

[0037] By setting all ejector pins 4 to be hollow inside, and all ejector pins 4 having air holes 41, and connecting pipes 9 connected to the support plate 3, the external air source is connected to the connecting pipes 9 before the toy figure is injected. During the injection process, the air holes 41 on the ejector pins 4 are blocked by the lower mold 1. When the ejector pins 4 are pushed out, the external air source is activated to supply air into the connecting pipes 9. The air holes 41 are no longer blocked by the lower mold 1, and the air is sprayed out from the air holes 41. The air is sprayed between the lower mold 1 and the toy figure, which accelerates the cooling of the toy figure and facilitates the demolding of the toy figure.

[0038] After cooling, the injection molding device pushes the support plate 3 upwards, and the ejector rod 4, ejector plate 5, and ejector column 6 move accordingly. These components push the toy figure between the lower mold 1 and the upper mold 2, allowing the ejector rod 4 to push the ejector ears, thus pre-demolding the toy figure and reducing the possibility of damage. The lower mold 1 is then separated from the toy figure, and the toy figure is manually removed from between the lower mold 1 and the upper mold 2, completing the production of the toy figure.

[0039] When pushing the toy figure to separate the lower mold 1 from the toy figure, the lower mold 1 is difficult to separate from the toy figure because the contact area between the head and body of the toy figure and the upper mold 2 is relatively large, and the toy figure is prone to damage.

[0040] When pushing the toy figure, the cylinder 7 replaces the top pillar 6 to contact the head of the toy figure, increasing the contact area with the head. The arc plate 8 replaces the top plate 5 to contact the body of the toy figure, increasing the contact area with the body.

[0041] Based on the above workflow, we can see that this utility model has the following effects:

[0042] By setting the air ducts 101 on the lower mold 1 and the upper mold 2 to be aligned and connected, the air blown out of the air duct 101 on the lower mold 1 collides with the air blown out of the air duct 101 on the upper mold 2, causing the air to spread rapidly between the lower mold 1 and the upper mold 2, thereby improving the cooling efficiency of the lower mold 1 and the upper mold 2.

[0043] The cylindrical plate 7 replaces the top plate 6 to contact the head of the toy figure, increasing the contact area with the head. The arc plate 8 replaces the top plate 5 to contact the body of the toy figure, increasing the contact area with the body and facilitating the separation of the toy figure from the lower mold 1.

[0044] The additional technical effects of this utility model are as follows:

[0045] Among them, such as Figure 3 As shown, there is a gap between the top plate 5 and the arc plate 8, and a gap between the top pillar 6 and the cylinder 7. After the ejector rod 4 pushes the ejector ear, the gap between the top plate 5 and the arc plate 8 decreases, and the gap between the top pillar 6 and the cylinder 7 decreases. After the ejector ear loses contact with the lower mold 1, the ejector ear causes the edge of the toy figure to separate from the lower mold 1, reducing the contact area between the toy figure and the lower mold 1, which is conducive to the demolding of the toy figure. Then the top plate 5 pushes the arc plate 8, and the top pillar 6 pushes the cylinder 7 to demold the toy figure.

[0046] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
