DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] like Figure 1-10The present embodiment shows a tray structure for injection molding a cup body, which is suitable for on-site storage and positioning of a cylindrical structure, one end of which is open and the other end is closed. In the present embodiment, the tray structure is particularly suitable for on-site storage and positioning of a cup body 6. The tray structure includes a lower tray 1 and an upper tray 3. The upper tray 3 cooperates with the lower tray 1 in an up-and-down manner so that the upper tray 3 has a positioning state in which it is positioned on the lower tray 1, and a separation state in which it moves upward to be separated from the lower tray 1 up and down. Specifically, the upper tray 3 and the lower tray 1 are formed by sheet metal bending. A plurality of positioning protrusions 11 are distributed and processed on the lower tray 1. The plurality of positioning protrusions 11 enclose a positioning area for limiting the horizontal movement of the upper tray 3. In the aforementioned positioning state, the upper tray 3 is placed in the positioning area.

[0031] Several limiting sleeves 4 are installed on the upper tray 3 along its width direction. The interior of the limiting sleeve 4 forms a cup body limiting channel 41 extending up and down. The cup body 6 in this embodiment can be inserted into the cup body limiting channel 41 in an upright posture. A first matching component 5 is installed on the upper tray 3 corresponding to each cup body limiting channel 41. The first matching component 5 includes a first bracket 51 and a first spring piece 52. The first bracket 51 is formed by bending the sheet metal. The first bracket 51 includes a first fixed section 511, an interlaced section 512 and a first bent section 513 connected in sequence. The first fixed section 511 is fixedly connected to the upper tray 3, and the interlaced section 512 is interlaced up and down in the cup body limiting channel 41. A accommodating space is formed between the interlaced section 512 and the cup body limiting channel 41, and the cup body 6 can be inserted into the accommodating space. The first bent section 513 is located above the cup body limiting channel 41. The first bending section 513 includes a first extension section that is bent from the upper end of the insertion section 512 toward one side in the horizontal direction and a second extension section that is bent downward and extended from the free end of the first extension section. The aforementioned first elastic sheet 52 is a conventional component of the prior art, which is made of metal parts. The first elastic sheet 52 is fixed to the second extension section. When the first elastic sheet 52 is pressed, the elastic end of the first elastic sheet 52 forms an elastic force that is opposite to the insertion section 512.

[0032] The second mating component 2 is installed on the aforementioned lower tray 1 corresponding to the first mating component 5. The second mating component 2 includes a second bracket 21 and a second elastic piece 22 installed on the second bracket 21. Among them, the second bracket 21 is formed by bending a sheet metal. The second bracket 21 includes a second fixed section 211, a limiting section 212 and a second bending section 213 connected in sequence. The limiting section 212 extends in the horizontal direction, and the second bending section 213 is located above the limiting section 212, which includes a vertical extension section that is bent upward and extended from the free end of the limiting section 212, a third extension section that is bent and extended from the upper end of the vertical extension section to one side in the horizontal direction, and a fourth extension section that is bent downward and extended from the free end of the third extension section. The aforementioned second elastic piece 22 is a conventional component of the prior art and is processed from a metal part. The second elastic piece 22 is fixed to the fourth extension section, and when the second elastic piece 22 is pressed, the elastic end of the second elastic piece 22 forms an elastic force facing away from the vertical extension section.

[0033] When specifically matched, in the aforementioned positioning state, the first spring sheet 52 and the second spring sheet 22 of the upper tray 3 are arranged opposite to each other in the horizontal direction, and an elastic clamping space is formed between the two in the horizontal direction. And in this positioning state, the aforementioned limiting section 212 extends between the cup body limiting channel 41 and the elastic clamping space. And in the aforementioned positioning state, the cup body 6 has a positioning position that is sleeved on the periphery of the elastic clamping space and forms an upper and lower limiting match with the limiting section 212. By reasonably designing the position of the limiting section 212, in this positioning position, an upper and lower spacing is formed between the inner bottom surface of the cup body 6 and the top of the first bracket 51 and the top of the second bracket 21. Through the above-mentioned structural design, on the one hand, the cup body 6 abuts against the first spring sheet 52 and the second spring sheet 22 to clamp the cup body 6, and on the other hand, the cup body 6 abuts against the limiting section 212 to limit the downward movement of the cup body 6, so that the cup body 6 is positioned in this positioning position. Pull the upper tray 3 upward to separate the upper tray 3 from the lower tray 1, and switch the upper tray 3 to a separated state. In the separated state, the cup body 6 forms a limited position that is sleeved on the first bracket 51 and inserted into the cup body limiting channel 41. Specifically, when the upper tray 3 is switched from the positioning state to the separated state, the first bracket 51 contacts the inner bottom surface of the cup body 6 to lift the cup body 6 and leave the second elastic sheet 22 and the second bracket 21, so that the cup body 6 is only sleeved on the first bracket 51, and the cup body 6 moves downward relative to the first bracket 51 to be inserted into the cup body limiting channel 41.

[0034] In this embodiment, in the aforementioned positioning state, the first spring piece 52 and the second spring piece 22 are both located within the caliber of the cup body limiting passage 41, so that the projection of the formed elastic clamping space in the up-down direction is located in the cup body limiting passage 41. When the cup body 6 is located in the positioning position, the cup body 6 is located within the caliber of the cup body limiting passage 41, so that when the upper tray 3 is switched from the positioning state to the disengaged state, the cup body 6 can smoothly enter the cup body limiting passage 41.

[0035] In this embodiment, the aforementioned cup body limiting passage 41 includes a first passage 411 and a second passage 412 which are interconnected from top to bottom; the inner diameter of the first passage 411 gradually narrows from top to bottom. The inner diameter of the second passage 412 is adapted to the outer diameter of the cup body 6. Through the above structural design, the cup body 6 first enters the first passage 411 and then enters the second passage 412. The first passage 411 plays a guiding role so that the cup body 6 can smoothly enter the cup body limiting passage 41.

[0036] In this embodiment, a cup body 6 placement area is arranged on the tray away from the cup body limiting passage 41, and a plurality of placement grooves 31 adapted to the cup body 6 are formed on the cup body 6 in the placement area. The cup body 6 is placed in the placement groove 31 in a horizontally arranged posture. According to actual storage needs, the cup body 6 can be placed in the placement area and in the cup body limiting passage 41, which effectively increases the number of cup bodies 6 placed on the upper tray 3, and can distinguish cup bodies 6 at different processing stages, thereby enhancing the functionality of the upper tray 3.

[0037] During specific use, the upper tray 3 is placed in the positioning area of ​​the lower tray 1 to form a positioning state. The cup body 6 molded by the injection mold is placed in the placement slot 31 of the upper tray 3 in a horizontal posture, and according to actual needs, the cup body 6 is selected to be sleeved on the first bracket 51 and the second bracket 21, and positioned by the first spring 52 and the second spring 22, so that the cup body 6 is placed in the upper tray 3 in an upright posture. The upper tray 3 and the lower tray 1 are transferred as a whole to the subsequent processing station for further processing. After the processing is completed, according to actual needs, the upper tray 3 is lifted upward to switch the upper tray 3 to the disengaged state, the upper tray 3 and the lower tray 1 are separated from each other, the cup body 6 is lifted up and disengaged from the first spring 52 and the second spring 22 to release the positioning fixation, and at the same time, the cup body 6 moves downward relative to the first bracket 51 to be inserted into the limiting space of the cup body 6, so that the transfer and transportation of the cup body 6 is realized by transporting the upper tray 3 alone. In the above method, the cup body 6 can be positioned and fixed in an upright posture to facilitate processing such as laser engraving, and the cup body 6 can be automatically detached and stored on the upper tray 3, which simplifies the processing procedure, saves time and labor, and effectively meets the processing requirements of the injection molded cup body 6.
