Technical Field

[0001] This utility model relates to the field of molds, and more specifically, to a molding mold for an ear-blowing ball. Background Technology

[0002] A mold is a tool used to create shaped products. Different shapes of molds are used to create products of different shapes, such as... Figure 1 The blow-ear ball shown is formed by hot pressing a hemispherical body and a funnel-shaped body. Traditional mold forming involves developing two molds with different structures to form the hemispherical body and the funnel-shaped body respectively, which increases production costs. Therefore, there is an urgent need for a mold that can form the hemispherical body and the funnel-shaped body in one step. Utility Model Content

[0003] This utility model provides a molding die for an ear blower, aiming to solve the technical problem of molding the two-part structure of the ear blower into a single mold in one step.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a molding die for an ear-blowing ball, comprising, from top to bottom, a panel, a pad, an upper moving die, a lower fixed die, and a base. The upper moving die is fitted with an upper die core, and the lower fixed die is fitted with a lower die core. The upper die core has two semi-circular grooves and two funnel grooves. The lower die core includes a moving template and a fixed template. The moving template is placed on the fixed template. The fixed template is provided with two first forming pillars and two second forming pillars. The first forming pillars and the second forming pillars can slide through the moving template. The upper end face of the first forming pillar is a hemispherical protrusion, and the upper end of the second forming pillar is an inverted funnel-shaped protrusion.

[0005] Furthermore, a top rod is provided at the bottom of the moving template, and the top rod can slide through the fixed template, the lower fixed template, and the base.

[0006] Furthermore, the upper moving mold has a T-shaped glue inlet groove, and the horizontal ends of the glue inlet groove are connected to the semi-circular groove.

[0007] Furthermore, the bottom of the upper mold core has a cross-shaped diversion groove between the two funnel grooves, and the diversion groove is connected to the funnel groove.

[0008] Furthermore, the upper mold core is provided with an overflow groove around the semi-circular groove and the funnel groove.

[0009] Furthermore, the lower fixed mold is provided with positioning posts, and the upper moving mold has positioning grooves.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model relates to a mold structure for a blown ear ball that is simple, rationally designed, and includes a panel, a backing plate, an upper moving mold, a lower fixed mold, and a base. The upper moving mold houses the upper mold core, and the lower fixed mold houses the lower mold core. The upper mold core has two semi-circular grooves and two funnel-shaped grooves. The lower mold core includes a moving template and a fixed template. The moving template rests on the fixed template, which has two first forming pillars and two second forming pillars. The first and second forming pillars slide through the moving template. The upper end of the first forming pillar is a hemispherical protrusion, and the upper end of the second forming pillar is an inverted funnel-shaped protrusion. During injection molding, the semi-circular grooves cover the protrusions to form the hemispherical shape of the blown ear ball, and the funnel-shaped grooves cover the protrusions to form the funnel-shaped main body of the blown ear ball. This allows for the simultaneous molding of two different structures, reducing mold manufacturing costs. Attached Figure Description

[0029] Example

[0030] like Figure 1 The blow-ear ball 60 shown is formed by hot pressing a hemispherical body 601 and a funnel-shaped body 602.

[0031] Reference Figure 2-6 As shown, this utility model discloses a molding die for an ear-blowing ball 60, including a panel 10, a pad 20, an upper moving die 30, a lower fixed die 40, and a base 50 from top to bottom. The upper moving die 30 is fitted with an upper die core 301, and the lower fixed die 40 is fitted with a lower die core. The upper die core 301 has two semi-circular grooves 3011 and two funnel grooves 3012. The lower die core includes a moving template 401 and a fixed template 402. The moving template 401 is placed on the fixed template 402. Two first forming pillars and two second forming pillars are provided on the fixed template 402. The first forming pillars and the second forming pillars can slide through the moving template 401. The upper end of the first forming pillar is a hemispherical protrusion 4021, and the upper end of the second forming pillar is an inverted funnel-shaped protrusion 4022. Specifically, during mold closing, the semi-circular groove 3011 covers the hemispherical protrusion 4021 to form the hemispherical body 601, and the funnel groove 3012 covers the inverted funnel-shaped protrusion 4022 to form the funnel-shaped body 602.

[0032] Reference Figure 2-6 As shown, the upper moving mold 30 has a T-shaped injection groove 302. The horizontal ends of the injection groove 302 are connected to the semi-circular groove 3011. During injection molding, hot melt adhesive is drawn into the injection groove 302. The hot melt adhesive enters the semi-circular groove 3011 from the horizontal ends of the injection groove 302 and covers the gap of the hemispherical protrusion 4021. The direct injection method has high injection efficiency. Furthermore, the bottom of the upper mold core 301 has a cross-shaped flow channel between the two funnel grooves 3012. The flow channel is connected to the funnel grooves 3012. Hot melt adhesive flows from the injection groove 302 to the flow channel, and then from the flow channel into the funnel groove 3012, covering the gap between the inverted funnel-shaped protrusions 4022. The hot melt adhesive fills from bottom to top, ensuring sufficient filling.

[0033] Furthermore, the upper mold core 301 is provided with an overflow groove around the semi-circular groove 3011 and the funnel groove 3012. Excess hot melt glue will overflow into the overflow groove, which serves to collect the overflow glue.

[0034] Reference Figure 2-6 As shown, a push rod 4023 is provided at the bottom of the moving template 401. The push rod 4023 can slide through the fixed template 402, the lower fixed mold 40, and the base 50. Specifically, when the mold is opened, the upper mold core 301 and the lower mold core separate, and the product remains on the hemispherical protrusion 4021 and the inverted funnel-shaped protrusion 4022. The push rod 4023 pushes the moving template 401 upward, and the moving template 401 pushes the product upward to fall off the hemispherical protrusion 4021 and the inverted funnel-shaped protrusion 4022, thereby realizing the demolding of the product.

[0035] In addition, a positioning pin 403 is provided on the lower fixed mold 40, and a positioning groove 303 is opened on the upper moving mold 30. When the mold is closed for injection molding, the positioning pin 403 is inserted into the positioning groove 303 to realize the rapid closing of the upper moving mold 30 and the lower fixed mold 40, thereby improving the injection molding efficiency.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
