[0001] This application belongs to the field of milk tea cup manufacturing technology, and more specifically it relates to a milk tea cup injection mold that prevents the formation of air bubbles. Background Technology

[0002] Milk tea is a beverage made by mixing milk and tea. In modern society, the term milk tea generally includes various new cup drinks and fruit teas sold in milk tea shops. These include not only freshly made hand-shaken milk tea, but also bottled, canned, and bagged milk teas that are easy to sell. After the milk tea is prepared, it needs to be served in milk tea cups for sale. The production of milk tea cups requires injection molds.

[0003] Currently, Chinese patent CN216832026U discloses an injection mold for producing milk tea cups, which relates to the field of milk tea cups. The mold includes a base, a lower mold base on the top of the base, buffer sleeves fixedly connected to the four sides of the bottom of the lower mold base, buffer rods symmetrically arranged at the bottom of the four buffer sleeves, shock-absorbing springs symmetrically sleeved on the surface of the four buffer sleeves, a mold groove opened inside the top of the lower mold base, a lower mold core fixedly connected inside the mold groove, guide posts fixedly connected to the four sides of the top of the mold groove, and an upper mold base on the top of the lower mold base.

[0004] In the existing technology, similar injection molds cannot effectively release air during the injection process, which makes the produced milk tea cups prone to air bubbles, affecting the production quality of the milk tea cups. Therefore, there is room for improvement. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a milk tea cup injection mold that prevents the formation of air bubbles. Its advantage is that it can easily remove the air in the mold, reduce the formation of air bubbles during the injection process, and improve the production quality of milk tea cups.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a milk tea cup injection mold for preventing air bubbles, comprising a lower base plate, a plurality of lower templates on the top of the lower base plate, electric telescopic rods at the four corners of the outer wall of the top of the lower templates, piston rods of the electric telescopic rods connected to an upper template, an upper top plate on the top of the upper template, an injection hole in the middle of the top of the upper top plate, a flow channel in the interior of the upper top plate, the flow channel having a cross-shaped structure, an injection hole at the end of the flow channel, the injection hole communicating with the upper template, an exhaust channel in the interior of the upper top plate, the exhaust channel having a U-shaped structure, the exhaust channel being distributed along the edge of the flow channel, the depth of the exhaust channel being less than the depth of the flow channel, the injection hole communicating with the exhaust channel through a flow hole, and an exhaust hole on one side of the outer wall of the upper top plate, the exhaust hole communicating with the exhaust channel.

[0007] By adopting the above technical solution, when in use, molten plastic is injected into the distribution channel through the injection hole. The molten plastic is then distributed to each injection hole through the distribution channel. At the same time as the molten plastic enters the injection hole, the air between the upper and lower mold plates will pass through the vent hole to the vent channel and finally be discharged from the vent hole. This can easily remove the air in the mold, reduce the generation of bubbles during the injection molding process, and improve the production quality of milk tea cups.

[0008] In a preferred embodiment, the flow hole has a stepped structure.

[0009] By adopting the above technical solution, the stepped structure design facilitates the discharge of air from the mold through the flow holes, avoids interference from the molten plastic on the venting, and improves the smoothness of venting.

[0010] In a preferred embodiment: a discharge hole is provided on the outer wall of the other side of the top plate, and the discharge hole is connected to the diversion channel.

[0011] By adopting the above technical solution, the setting of the discharge hole can facilitate the exhaust of air through the auxiliary exhaust hole, thereby improving the exhaust rate.

[0012] In a preferred embodiment: a molding column is provided inside the lower template, and an electric heating rod is provided inside the molding column.

[0013] By adopting the above technical solution, the electric heating rod can be conveniently heated to preheat the mold and prevent the generation of air bubbles during injection molding.

[0014] In a preferred embodiment: the outer wall of the electric heating rod is provided with a plurality of heat-conducting blocks distributed at equal intervals, and the heat-conducting blocks are integrally formed with the electric heating rod.

[0015] By adopting the above technical solution, the setting of the heat-conducting block can increase the contact area between the electric heating rod and the molding column, thereby improving the heating rate of the molding column.

[0016] In a preferred embodiment: a sealing strip is provided at the connection between the upper template and the lower template, and the sealing strip has a ring structure.

[0017] By adopting the above technical solution, the sealing strip can be conveniently used to seal the connection between the upper and lower mold plates, preventing air from entering the mold during injection and reducing the generation of air bubbles.

[0018] In a preferred embodiment, the sealing strip is made of rubber.

[0019] By adopting the above technical solution, the sealing strip made of rubber material has good elasticity, which can quickly fill the gap between the upper and lower templates, thus improving the sealing effect.

[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] 1. During use, molten plastic is injected into the distribution channel through the injection hole. The molten plastic is then distributed to each injection hole through the distribution channel. As the molten plastic enters the injection hole, the air between the upper and lower mold plates passes through the vent hole to the vent channel and is finally discharged from the vent hole. This facilitates the removal of air from the mold, reduces the generation of air bubbles during injection molding, and improves the production quality of milk tea cups.

[0022] 2. The stepped structure design facilitates the discharge of air from the mold through the flow holes, preventing molten plastic from interfering with venting and improving venting smoothness; the discharge holes can also assist the auxiliary venting holes in venting, increasing the venting rate.

[0023] 3. The electric heating rod can easily heat the molding column, thereby preheating the mold and preventing the generation of air bubbles during injection molding; the heat-conducting block can increase the contact area between the electric heating rod and the molding column, improving the heating rate of the molding column.
