Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold for quick demolding. Background Technology

[0002] Currently, during the processing of the cup lid base, a rubber ring needs to be shaped and molded on the top edge of the base. The rubber ring is then tightly bonded to the cup lid base. Rubber needs to be injected into the mold to shape the rubber between the mold and the cup lid, thus completing the bonding between the cup lid base and the rubber ring. However, there will still be residue at the break point between the molded rubber ring and the rubber waste, requiring secondary processing. After the mold is opened, the cup lid base and the rubber ring will be stuck on the upper mold base, requiring manual removal after cooling. This increases the workload and reduces the demolding efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a mold for rapid demolding, which solves the issues of low demolding efficiency and high workload.

[0004] The technical solution adopted by this utility model is as follows: a quick-release mold, including a lower mold base and an upper mold base. The upper mold base is provided with an injection channel and an air extraction channel. The lower mold base is provided with an air extraction groove connected to the air extraction channel. A housing is installed on the lower mold base. A molding cavity is provided between the housing and the upper mold base. A scrap cavity and a feed cavity are provided between the lower mold base and the upper mold base. The feed cavity is connected to the injection channel. The scrap cavity is connected to the air extraction groove. The scrap cavity and the feed cavity are connected to the molding cavity. A first air blowing channel and a second air blowing channel are provided on the upper mold base. The first air blowing channel is connected to the second air blowing channel. The opening of the second air blowing channel is located above the housing.

[0005] Through the above technical solution, a rubber ring is formed in the molding cavity. During demolding, since the molding cavity is connected to the feeding cavity and the waste cavity, the upper mold base moves upward, and the waste in the feeding cavity and the waste in the waste cavity separate from the sealing ring. The rubber ring is tightly connected to the shell, and the gas in the second blowing channel blows to the upper surface of the shell, so that the shell and the rubber ring can quickly detach from the mold, which improves the demolding efficiency and reduces the workload of the user.

[0006] Furthermore, the second air-blowing channel opening is located above the exact center of the housing.

[0007] With the above technical solution, the opening of the second air blowing channel is located above the center of the shell, and the gas blown out of the second air blowing channel opening can blow towards the middle of the shell, making it easier for the shell to detach from the upper mold base.

[0008] Furthermore, the second air-blowing channel extends vertically downwards.

[0009] With the above technical solution, the extension direction of the second air blowing channel is vertically downward, and the gas blown out of the opening of the second air blowing channel can blow vertically onto the shell, increasing the efficiency of the shell falling off from the upper mold base.

[0010] Furthermore, an air inlet cavity is provided between the top of the housing and the bottom of the second air blowing channel.

[0011] Through the above technical solution, the gas blown out of the second air blowing channel outlet will enter the air inlet cavity and then blow onto the upper surface of the shell, increasing the blowing area and making it easier for the shell to detach from the upper mold base.

[0012] Furthermore, an arc-shaped groove is provided on the top of the housing, and the arc-shaped groove is located directly below the second air blowing channel.

[0013] With the above technical solution, the gas blown from the outlet of the second air blowing channel to the arc groove is more concentrated, making it easier for the shell to detach from the upper mold base.

[0014] Furthermore, the upper mold base includes a first upper mold body and a second upper mold body. The first upper mold body or the second upper mold body is provided with an installation groove. The second air blowing channel passes through the middle of the installation groove. A sealing ring is provided in the installation groove. The sealing ring is tightly fitted with the second upper mold body or the first upper mold body.

[0015] Through the above technical solution, the upper mold base is composed of a first upper mold body and a second upper mold body, which facilitates the replacement of the second upper mold body and adapts to shells of different shapes; the first upper mold body or the second upper mold body is provided with an installation groove, and a sealing ring is provided in the installation groove, so that gas will not leak from the side wall of the second air blowing channel, thereby increasing the air blowing efficiency.

[0016] Further, the feeding chamber includes a first feeding channel, a second feeding channel, and a first cavity. The second feeding channel is connected to the forming cavity. The cross-sectional area of ​​the first feeding channel is larger than that of the second feeding channel. The cross-sectional area of ​​the second feeding channel gradually decreases as it approaches the forming cavity, and the cross-sectional area of ​​the first feeding channel gradually increases as it approaches the first cavity. The waste chamber includes a first discharge channel, a second discharge channel, and a second cavity. The first discharge channel is connected to the forming cavity. The cross-sectional area of ​​the second discharge channel is larger than that of the first discharge channel. The cross-sectional area of ​​the first discharge channel gradually decreases as it approaches the forming cavity, and the cross-sectional area of ​​the second discharge channel gradually increases as it approaches the second cavity.

[0017] Through the above technical solution, the cross-sectional area of ​​the first feeding channel is larger than that of the second feeding channel. The cross-sectional area of ​​the second feeding channel gradually decreases as it approaches the molding cavity, while the cross-sectional area of ​​the first feeding channel gradually increases as it approaches the first cavity. The connection between the rubber ring and the waste material in the feeding cavity is smaller, making it easier to break the connection between the rubber ring and the waste material in the feeding cavity during demolding, thus improving demolding efficiency. Similarly, the cross-sectional area of ​​the second discharge channel is larger than that of the first discharge channel. The cross-sectional area of ​​the first discharge channel gradually decreases as it approaches the molding cavity, while the cross-sectional area of ​​the second discharge channel gradually increases as it approaches the second cavity. The connection between the rubber ring and the waste material in the waste material cavity is smaller, making it easier to break the connection between the rubber ring and the waste material in the waste material cavity during demolding, thus improving demolding efficiency.

[0018] Furthermore, a first threaded groove is provided on the first cavity, and a second threaded groove is provided on the second cavity. Both the first threaded groove and the second threaded groove are provided on the lower mold base.

[0019] With the above technical solution, the waste material in the feeding chamber will be stuck on the first threaded groove, and the waste material in the waste material chamber will be stuck on the second threaded groove. When demolding, the upper mold base moves upward, making it easier for the waste material in the feeding chamber and the waste material in the waste material chamber to quickly separate from the sealing ring.

The connection between the rubber ring 9 and the waste material in the feeding cavity 5 is smaller, making it easier to break the connection between the rubber ring 9 and the waste material in the feeding cavity 5 during demolding, thus improving demolding efficiency. The cross-sectional area of ​​the second discharge channel 602 is larger than that of the first discharge channel 601. The cross-sectional area of ​​the first discharge channel 601 gradually decreases as it approaches the molding cavity 4, while the cross-sectional area of ​​the second discharge channel 602 gradually increases as it approaches the second cavity 603. The connection between the rubber ring 9 and the waste material in the waste material cavity 6 is smaller, making it easier to break the connection between the rubber ring 9 and the waste material in the waste material cavity 6 during demolding, thus improving demolding efficiency.
