Abstract
Description
Technical Field
[0001] This utility model relates to an injection mold for a folding basket. Background Technology
[0002] A folding basket is a storage container designed to fold, reducing its space requirements and making it easy to carry. To save costs and enable modular production, most folding baskets are made of plastic. Therefore, the production of plastic folding baskets is achieved using matching injection molds and injection molding machines.
[0003] Because plastic folding baskets can both open and fold, they are assembled from multiple plastic parts. Currently, each part required for assembling a plastic folding basket is equipped with a separate injection mold. Although each part can achieve the effect of "one part producing multiple parts", it requires a large investment in mold manufacturing costs, resulting in high production costs. Moreover, in order to save the steps of mold installation and removal, multiple injection molding machines need to be equipped to work simultaneously. The capital investment in purchasing injection molding machines and energy consumption are both large, which needs further improvement. Utility Model Content
[0004] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide an injection mold for a folding basket that greatly reduces mold manufacturing costs, thereby reducing production costs, and also reduces the capital investment and energy consumption required to purchase an injection molding machine.

[0009] Each of the first U-shaped grooves has a base formed at both ends facing the positioning module, and correspondingly, each of the second U-shaped grooves has a base cavity at both ends; each base cooperates with a corresponding base cavity.
[0010] Preferably, a first slot assembly is formed at each of the four corners of the rectangular annular protrusion. The first slot assembly includes two first opening slots arranged horizontally in sequence and a second opening slot located on one side of the two first opening slots. Correspondingly, four first insert modules are embedded in the moving module in pairs. The first insert module includes two first core strips horizontally inserted and fixed in the moving module and a second core strip located on one side of the two first core strips. The ends of the two first core strips respectively cooperate with the two first opening slots, and the ends of the second core strips cooperate with the second opening slots.

[0014] Preferably, on the bottom surface of each base cavity, two second extension grooves are formed on one side edge near the second U-shaped groove, respectively located on the left and right sides of the second U-shaped core bar and communicating with the interior of the second U-shaped groove.
