Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold technology and relates to an injection mold for a one-piece milk tea cup lid. Background Technology
[0002] Milk tea cup lids are plastic products. Plastic products are usually produced using injection molds. The working principle of injection molds is as follows: after the plastic raw material is heated to a molten state, it is injected into the molding cavity set inside the mold. After the molding cavity is filled, the mold is rapidly cooled, and the molten plastic raw material cools and solidifies to form the required plastic part. Using injection molds to produce plastic products has advantages such as high precision and high efficiency.
[0003] To make drinking milk tea more convenient, a spout is provided on the milk tea cup lid, allowing customers to drink directly without using a straw. When customers are not drinking milk tea, the spout needs to remain sealed. Current milk tea cup lids typically use a cover that is attached to the spout, but this cover is easily lost after being opened and removed. Therefore, a one-piece buckle needs to be provided on the cup lid. For ease of production, the structure of the buckle and the cup lid needs to be directly formed inside the molding cavity of the injection mold. Summary of the Invention
[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing an injection mold for an integrated milk tea cup lid. The technical problem to be solved by this utility model is: how to make the structure of the buckle and the cup lid integrally formed inside the mold.
[0005] The objective of this utility model can be achieved through the following technical solution: An injection mold for a one-piece milk tea cup lid includes a top plate, a heating plate fixedly connected to one side of the top plate, a fixed template fixedly connected to the other side of the heating plate, a slidingly connected moving template on the other side of the fixed template, a plurality of molding cavities at the connection between the fixed template and the moving template, a plurality of sub-cavities between the fixed template and the moving template, each sub-cavity being connected to a single molding cavity, a cup lid being injection molded inside the molding cavity, and a buckle being provided inside the sub-cavities, the buckle being integrally connected to the cup lid.
[0006] In this design, a secondary cavity is connected to a forming cavity. The secondary cavity and the forming cavity are set inside the mold in a matching manner, which allows the cup lid that has cooled and formed inside the forming cavity to be integrally connected with the connecting part formed inside the secondary cavity without secondary processing. Furthermore, the structure of multiple forming cavities and secondary cavities between the moving mold plate and the fixed mold plate allows multiple cup lid products to be produced in one mold closing process, improving production efficiency. Through the above method, the buckle is integrally connected with the cup lid, which not only facilitates sealing the cup lid, but also prevents the buckle from being lost.
[0007] In the injection mold of the connected milk tea cup cover, the top of the cover is provided with a drinking nozzle, the buckle is connected to the outermost edge of the cover, and the buckle can be turned to cover the drinking nozzle.
[0008] In the injection mold of the connected milk tea cup cover, the top of the cover is provided with a drinking nozzle, the buckle is connected to the outermost edge of the cover, and the buckle can be turned to cover the drinking nozzle.
[0009] In the injection mold of the connected milk tea cup cover, the top of the cover is provided with a drinking nozzle, the buckle is connected to the outermost edge of the cover, and the buckle can be turned to cover the drinking nozzle.
[0010] In the injection mold of the connected milk tea cup cover, the top of the cover is provided with a drinking nozzle, the buckle is connected to the outermost edge of the cover, and the buckle can be turned to cover the drinking nozzle.
[0011] In the injection mold of the connected milk tea cup cover, the top of the cover is provided with a drinking nozzle, the buckle is connected to the outermost edge of the cover, and the buckle can be turned to cover the drinking nozzle.
[0012] In the injection mold of the connected milk tea cup cover, the top of the cover is provided with a drinking nozzle, the buckle is connected to the outermost edge of the cover, and the buckle can be turned to cover the drinking nozzle.
[0013] In the injection mold of the connected milk tea cup cover, the top of the cover is provided with a drinking nozzle, the buckle is connected to the outermost edge of the cover, and the buckle can be turned to cover the drinking nozzle.
[0014] Compared with the prior art, the injection mold of the connected milk tea cup cover has the following advantages:
[0015] 1. In this solution, a secondary cavity is connected to a forming cavity. The secondary cavity and the forming cavity are set inside the mold in a matching manner. This allows the cup lid, which is cooled and formed inside the forming cavity, to be integrally connected with the connecting part formed inside the secondary cavity. No secondary processing is required. The buckle is integrally connected with the cup lid, which not only facilitates sealing the cup lid, but also prevents the buckle from being lost.
