Description

Technical Field

[0001] This utility model relates to the field of paper tableware production technology, specifically a paper tableware forming mold based on air blowing demolding. Background Technology

[0002] In today's society, with the increasing awareness of environmental protection, disposable paper tableware is being used more and more widely in the catering industry due to its biodegradable and environmentally friendly characteristics. In the early days, the demolding of paper tableware mostly relied on manual operation, where workers had to manually remove the formed paper tableware from the mold. This method was not only inefficient and difficult to meet the needs of large-scale production, but also difficult to precisely control the force of manual operation, which easily caused damage and deformation of the paper tableware, resulting in a high rate of product defects.

[0003] Existing demolding methods typically utilize simple mechanical structures such as ejector pins. While these methods improve efficiency to some extent, they still cannot guarantee uniform and smooth demolding for complex-shaped paper tableware. During the demolding process, the significant friction between the paper tableware and the mold can easily cause scratches and damage to the surface of the paper tableware, affecting the product's appearance and quality. Utility Model Content

[0004] The purpose of this invention is to provide a paper tableware forming mold based on air blowing demolding, which has the advantages of quick demolding and better protection of paper tableware during demolding. It solves the problem that current paper tableware forming molds cannot guarantee uniform and smooth demolding when producing paper tableware with complex shapes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper tableware forming mold based on air blowing demolding, comprising a mold mechanism, the mold mechanism comprising a base, a worktable provided at the top of the base, a lifting platform provided above the worktable, and an injection mold fitted in the middle of the top of the worktable, an injection groove provided in the middle of the top of the lifting platform, the injection mold comprising a lower mold mechanism and an ejector mechanism, the ejector mechanism being located below the lower mold mechanism and extending upward into the lower mold mechanism, an air inlet pipe communicating with the lower mold mechanism being provided on the side of the base, the lower mold mechanism comprising a lower template, and a mold groove being provided at the top of the lower template.

[0006] Preferably, the mold groove has six through holes arranged in a ring array around its axis at equal intervals, the lower template has a ring groove with a circular vertical cross section, and the outer edge of the ring groove has six through slots that are respectively connected to the through holes.

[0007] Preferably, the lower template has a long groove with a connecting ring groove, and each through hole has a limiting groove at its bottom end, with a limiting frame at the bottom end of the limiting groove.

[0008] Preferably, the ejector pin mechanism includes six long columns extending into the lower mold plate, and each of the long columns has a positioning block on the side facing the center of the mold mechanism, and the top side of the positioning block is provided with a guide surface.

[0009] Preferably, the thickness of each positioning block is greater than the inner diameter of the through groove.

[0010] Preferably, a support plate is connected to the bottom of several of the long columns. The support plate is arranged in a star shape, and a hydraulic rod is provided in the middle of the bottom end of the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a lower template, mold groove, through hole, annular groove, long groove, limiting groove, limiting frame, long column, positioning block, support plate, and hydraulic rod. After the paper tableware is injection molded, the hydraulic rod is activated, causing the support plate to descend. The support plate then drives the long column to descend, causing the positioning block to slide within the limiting groove and limiting frame. This moves the positioning block out of the through groove, releasing the seal on the through groove and sealing the bottom of the through hole. Gas is injected into the annular groove through the long groove, and air is supplied into the through hole through the through groove, forming an air cushion between the paper tableware and the mold. This reduces the friction between the paper tableware and the mold. Since air-blowing demolding separates the paper tableware from the mold using the air cushion, it avoids problems such as deformation and damage that may occur in traditional demolding methods, thus ensuring the quality of the paper tableware.
