Technical Field

[0001] This utility model relates to the technical field of environmentally friendly paper tray processing, specifically an environmentally friendly paper tray hot pressing molding die. Background Technology

[0002] Eco-friendly paper trays (also known as molded pulp) are biodegradable and environmentally friendly packaging materials made from waste paper, pulp, or plant fibers through molding and drying processes. Their core advantage lies in replacing polystyrene foam (EPS), reducing "white pollution," and they are widely used in industrial, food, agricultural, and medical fields. During its molding process, corresponding molds are required for assistance. For example, there is an environmentally friendly paper tray hot pressing mold with patent publication number CN207891645U, which realizes the protection of the second cavity of the main body by using a protective cover when the main body is raised, to prevent foreign objects from falling into the cavity, avoid damage to the cavity, and ensure service life.

[0003] However, since this device does not allow the main body to be fully opened, it is inconvenient to pick up materials and its practicality is insufficient. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an environmentally friendly paper tray thermoforming mold with a protective mechanism that allows for priority contact and delayed departure, optimizes protective performance, enables complete opening of the mold, facilitates material handling, and improves practicality.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly paper tray hot-press forming mold, comprising a main body 1, an environmentally friendly paper tray mold groove, a main body 2, and a hot-pressing mold. The environmentally friendly paper tray mold groove is provided on the inner side of the middle part of the main body 1, and the hot-pressing mold is provided on the middle part of the bottom side of the main body 2. The hot-pressing mold is shaped to match the environmentally friendly paper tray mold groove. It also includes guide sleeves, guide rods, upper limit plates, connecting springs, connecting plates, and retaining ring frames. A set of guide sleeves is connected to the inner side of the left and right parts of the main body 2, and the inner wall of each set of guide sleeves is vertically slidably connected to the outer wall of a set of guide rods. The top side of the guide rods is connected to the middle part of the bottom side of the upper limit plate. The bottom sides of the two sets of guide rods are respectively connected to the middle side of the top left and right parts of the retaining ring frame via a set of connecting plates. A connecting spring is connected to the outer side of each set of guide sleeves at the bottom end of the main body 2 and the outer side of the guide rod at the top of the connecting plate. A connecting mechanism is provided at the top of the main body 2, and a guide structure is provided between the main body 2 and the main body 1.

[0006] Preferably, the connecting mechanism includes a mounting sleeve, an inner frame, a long bolt, and a nut. The middle part of the top two sides of the main body is connected to the bottom side of the mounting sleeve. The inner side of the mounting sleeve and the outer side of the inner frame are detachably inserted. The inner frame is connected to the outer side of the corresponding hydraulic cylinder rod. The long bolt passes through the inner groove of the mounting sleeve and the inner frame simultaneously and is detachably screwed on the protruding side by a nut.

[0007] Preferably, the guide structure includes a constraint sleeve and constraint slide rods. The four corner sides of the top of the main body one are respectively connected to the bottom side of a set of constraint slide rods, and the interior of the four corner sides of the main body two are respectively connected to the outer side of a set of constraint slide rods. The inner wall of each set of constraint sleeves is slidably connected to the outer wall of the constraint slide rod on the same side.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides an environmentally friendly paper tray thermoforming mold, which has the following beneficial effects: When the main body 2 is in the upper position, it can feed material into the environmentally friendly paper mold slot through the external feeding pipe. Then, the hydraulic cylinder connects the main body 2 through the connecting mechanism. The main body 2 descends vertically under the action of the guide structure. During this process, the retaining ring extends downward under the elastic action of the connecting spring, so that the retaining ring first fits against the outside of the environmentally friendly paper mold slot at the top of the main body 1. As the main body 2 continues to move downward, the connecting spring is compressed and slids within the guide sleeve through the guide rod, so that the retaining ring is stably covered and protected outside the environmentally friendly paper mold slot until the main body 2 is hot-pressed into the environmentally friendly paper mold slot by the hot press mold. After completion, the main body 2 rises back, recovers elastically through the connecting spring, and slides under the constraint of the guide sleeve by two sets of guide rods. It is limited by the upper side of the upper limit plate and lifted by the retaining ring connected by the connecting plate until the retaining ring is separated from the upper part of the main body 1, so that the environmentally friendly paper mold slot can be fully exposed for easy material removal. A protective mechanism that can prioritize contact and delay departure is set up to optimize the protective performance, realize the complete opening of the mold, facilitate material removal, and improve practicality.
