Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically to an adjustable date stamp for plastic molds. Background Technology

[0002] Plastic molds are used to mold plastic products and are crucial in the plastic product manufacturing process. They can give plastic raw materials precise shape, size and surface characteristics, and their quality and performance directly affect the quality of plastic products and production efficiency.

[0003] In the production process of plastic products, it is often necessary to imprint information such as production date and batch number on the plastic products to facilitate product traceability and management. The main function of the date stamp is to clearly mark the time. In the manufacturing field, such as when producing plastic products, the date stamp can imprint information such as production date and batch number on the product surface to facilitate product quality traceability, inventory management and after-sales maintenance.

[0004] Most existing date stamps for plastic molds are fixed structures. Once engraved, the date information cannot be changed, resulting in a short lifespan for the date stamps. If the date needs to be changed, a new date stamp must be made, which not only wastes time but also increases production costs. Therefore, there is an urgent need to design an adjustable date stamp for plastic molds to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable date stamp for plastic molds to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable date stamp for plastic molds includes a mounting cylinder. A fixed cylinder is slidably mounted at one end of the mounting cylinder in a horizontal direction. A rotating cylinder is rotatably mounted on the inner side of the fixed cylinder. A screw is threaded into the inner side of the rotating cylinder in a horizontal direction. A rotating disk is fixedly mounted at the end of the screw away from the inner side of the mounting cylinder. An arrow protrusion is fixed in the middle of the surface of the rotating disk away from the mounting cylinder. Date protrusions are fixedly mounted on both sides of the arrow protrusion on the surface of the rotating disk near the arrow protrusion. A month ring is fixed on the edge of the surface of the mounting cylinder near the rotating disk on the outer side of the rotating disk. A plurality of month protrusions are fixedly fixed at intervals along the circumferential direction on the surface of the month ring away from the mounting cylinder.

[0008] Preferably, the arrow protrusion has an annual groove in the middle of the surface away from the rotating disk, and the annual groove can be set to the desired year number.

[0009] Preferably, the monthly bumps are located on the monthly ring and are distributed at equal intervals along the circumference, with twelve corresponding to the twelve month numbers. The date bumps can be set to the desired date numbers.

[0010] Preferably, the outer ring diameter of the rotating disk is larger than the inner ring diameter of the mounting cylinder, and the outer ring of the rotating disk and the inner ring of the lunar ring are in a matching and fitting state.

[0011] Preferably, there is a certain gap between the inner ring surface of the fixed cylinder and the outer ring surface of the rotating cylinder, and a high-resistance bearing is installed between the inner ring surface of the fixed cylinder and the outer ring surface of the rotating cylinder.

[0012] Preferably, a fixing ring is fixed in the middle of the inner annular surface of the mounting cylinder, and a spring is fixedly installed on the surface of the fixing cylinder near the fixing ring. The end of the spring away from the fixing cylinder is fixedly installed with a corresponding position on the opposite surface of the fixing ring.

[0013] Preferably, a connecting rod is fixed to the surface of the rotating cylinder away from the rotating disk, the connecting rod is in a horizontal state, and a push-pull handle is fixed to the surface of the connecting rod away from the rotating cylinder.

[0014] Preferably, a mounting plate is fixed to the end of the outer ring surface of the mounting cylinder away from the lunar ring, and mounting holes are provided at all four corners of the mounting plate, with each mounting hole penetrating the corresponding two sides of the mounting plate.

[0015] In the above technical solution, the adjustable date stamp for plastic molds provided by this utility model has the following advantages:

[0016] (1) The year, month and date in this date stamp are all adjustable so that they can be adjusted to follow the production date of the plastic products. This helps to ensure the service life of this date stamp. When adjusting the month and date in this date stamp, there is no need to remake a new date stamp, which helps to save time in adjusting the date stamp and saves the cost of using and producing the date stamp.

[0017] (2) When the rotating cylinder rotates, it will rotate along the inner side of the fixed cylinder through the high resistance bearing. The high resistance bearing will apply frictional resistance between the fixed cylinder and the rotating cylinder to facilitate the positioning of the rotating cylinder after rotation, and to position the rotating disk and arrow protrusion after rotation, which helps to ensure the stable use of the adjusted rotating disk and arrow protrusion.

[0018] (3) The rotating disk can be pushed out through the connecting rod and push-pull handle to facilitate the replacement of the rotating disk. The spring can limit the movement between the fixed cylinder and the fixed ring. Under the action of its own elastic force, the spring can pull the rotating disk through the fixed cylinder, high resistance bearing, rotating cylinder and screw to reset the rotating disk and arrow protrusion after rotation adjustment.

[0027] like Figure 1-5As shown in the figure, an adjustable date stamp for plastic molds provided by this utility model embodiment includes an installation cylinder 1. A fixed cylinder 10 is slidably installed at one end of the installation cylinder 1 in the horizontal direction. A rotating cylinder 11 is rotatably installed on the inner side of the fixed cylinder 10. A screw 12 is threaded into the inner side of the rotating cylinder 11 in the horizontal direction. A rotating disk 6 is fixedly installed at the end of the screw 12 away from the inner side of the installation cylinder 1. An arrow protrusion 8 is fixed in the middle of the surface of the rotating disk 6 away from the installation cylinder 1. Date protrusions 7 are fixedly installed on both sides of the surface of the rotating disk 6 near the arrow protrusion 8. A monthly ring 4 is fixed on the edge of the surface of the installation cylinder 1 near the rotating disk 6 on the outer side of the rotating disk 6. A plurality of monthly protrusions 5 are fixed at intervals in the circumferential direction on the surface of the monthly ring 4 away from the installation cylinder 1.

[0028] In this embodiment, an arrow protrusion 8 is fixed in the middle of the surface of the rotating disk 6 away from the mounting cylinder 1. The arrow protrusion 8 is used to point to the corresponding monthly protrusion 5 on the monthly ring 4 to mark the corresponding production month.

[0029] Specifically, an annual groove 9 is provided in the middle of the surface of the arrow protrusion 8 on the side away from the rotating disk 6. The annual groove 9 can be set to the required year number and is used to mark the corresponding production year.

[0030] In this embodiment, a lunar ring 4 is fixed on the edge of the surface of the mounting cylinder 1 near the rotating disk 6 on the outside of the rotating disk 6, and a number of lunar protrusions 5 are fixed at intervals along the circumferential direction on the surface of the lunar ring 4 away from the mounting cylinder 1.

[0031] Specifically, the monthly bump 5 is located on the monthly ring 4 and is distributed at equal intervals along the circumference, corresponding to the twelve month numbers. The date bump 7 can be set to the required date number, and the production date can be displayed intuitively through the date bump 7.

[0032] In this embodiment, a rotating disk 6 is fixedly installed at the end of the screw 12 away from the inner side of the mounting cylinder 1.

[0033] Specifically, the outer ring diameter of the rotating disk 6 is larger than the inner ring diameter of the mounting cylinder 1, and the outer ring of the rotating disk 6 and the inner ring of the lunar ring 4 are in a matching and fitting state.

[0034] In this embodiment, a rotating cylinder 11 is rotatably mounted on the inner side of the fixed cylinder 10.

[0035] Specifically, there is a certain gap between the inner ring surface of the fixed cylinder 10 and the outer ring surface of the rotating cylinder 11. A high-resistance bearing 17 is installed between the inner ring surface of the fixed cylinder 10 and the outer ring surface of the rotating cylinder 11. The high-resistance bearing 17 can apply resistance between the fixed cylinder 10 and the rotating cylinder 11 to position the rotating cylinder 11 after rotation.

[0036] Specifically, a fixing ring 14 is fixed in the middle of the inner ring surface of the mounting cylinder 1, and a spring 13 is fixedly installed on the surface of the fixing cylinder 10 near the fixing ring 14. The end of the spring 13 away from the fixing cylinder 10 is fixedly installed with the corresponding position on the opposite surface of the fixing ring 14. The spring 13 can limit the movement between the fixing cylinder 10 and the fixing ring 14.

[0037] Specifically, a connecting rod 15 is fixed to the surface of the rotating cylinder 11 away from the rotating disk 6. The connecting rod 15 is in a horizontal state, and a push-pull handle 16 is fixed to the surface of the connecting rod 15 away from the rotating cylinder 11.

[0038] Specifically, an installation plate 2 is fixed to the end of the outer ring surface of the installation cylinder 1 that is away from the lunar ring 4. Installation holes 3 are opened at the four corners of the installation plate 2, and the installation holes 3 penetrate the two sides of the corresponding position on the installation plate 2.

[0039] The work steps are as follows:

[0040] 1. When this date stamp needs to be used, insert the mounting cylinder 1 of this date stamp into the corresponding position on the matching plastic mold, so that the mounting cylinder 1 penetrates the plastic mold, and the rotating disk 6 faces the inside of the plastic mold, and the push-pull handle 16 faces the outside of the plastic mold. Then, install the mounting plate 2 with the plastic mold installed on the outside through the external bolts and the mounting holes 3 on the mounting plate 2. The mounting plate 2 can fix and limit the mounting cylinder 1 and the various components assembled on the mounting cylinder 1, so as to facilitate the stable use of the mounting cylinder 1 and the various components assembled on the mounting cylinder 1.

[0041] 2. After the date stamp is installed between the plastic mold and the external plastic mold, during the production and processing of plastic products by the plastic mold, the date information of the produced plastic products will be printed on the plastic products through the monthly bump 5 on the monthly ring 4, the date bump 7 on the rotating disk 6, the arrow bump 8 and the year groove 9 on the arrow bump 8. The corresponding month can be seen intuitively through the monthly bump 5 pointed to by the printed arrow bump 8.

[0042] 3. When it is necessary to modify the printed month information, it is not necessary to disassemble the date stamp. Only the push-pull handle 16 needs to be rotated. When the push-pull handle 16 rotates, it can drive the rotating cylinder 11 to rotate through the connecting rod 15. The rotating cylinder 11 can drive the rotating disk 6 to rotate through the screw 12. When the rotating disk 6 rotates, it can drive the arrow protrusion 8 to rotate, so that the arrow of the arrow protrusion 8 points to different numbers on the month ring 4 to correspond to different months. When the rotating cylinder 11 rotates, it will rotate along the inner side of the fixed cylinder 10 through the high resistance bearing 17. The high resistance bearing 17 will apply frictional resistance between the fixed cylinder 10 and the rotating cylinder 11 to facilitate the positioning of the rotated cylinder 11 after rotation, so as to position the rotating disk 6 and the arrow protrusion 8 after rotation.

[0043] IV. When it is necessary to change the date or year in this date stamp, it is not necessary to disassemble the date stamp. Push the push-pull handle 16 toward the mounting cylinder 1, so that the push-pull handle 16 drives the connecting rod 15 to move. The connecting rod 15 can drive the rotating disk 6 and the arrow protrusion 8 to move away from the mounting cylinder 1 through the rotating cylinder 11 and the screw 12, further fixing the push-pull handle 16 and rotating the rotating disk 6, so that the rotating disk 6 drives the screw 12 to rotate along the inside of the rotating cylinder 11, so that the screw 12 moves out along the inner side of the rotating cylinder 11, so that the rotating disk 6 can be removed and replaced. The rotating disk 6, arrow protrusion 8 and date protrusion 7 of the same year but different dates can be reused to ensure the service life of this date stamp and facilitate the adjustment of the month and date in this date stamp.
