Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing equipment, and in particular to a caliper date mold ejection device. Background Technology
[0002] In the manufacturing process of caliper date dies, the ejector device is a key component that ensures smooth demolding and guarantees production efficiency and product quality. With the continuous improvement of industrial automation and the increasingly stringent requirements for caliper date die production, higher demands are being placed on the performance, precision, and stability of the ejector device.
[0003] Traditional caliper date mold ejection devices often have some shortcomings. For example, some ejection devices have relatively simple structures, making it difficult to accurately control the ejection force and distance during the ejection process. This may result in uneven force on the product during demolding, leading to deformation, damage, and other problems, thus affecting the product yield. Moreover, some traditional devices are inconvenient to adjust. When adjustments are needed for caliper date molds of different specifications or requirements, the operation is cumbersome and time-consuming, reducing production efficiency and increasing production costs.
[0004] Furthermore, during long-term production operation, the various components of the ejection device are prone to wear and loosening due to frequent reciprocating motion, which in turn affects the overall performance and stability of the ejection device. Traditional devices lack effective adaptive adjustment mechanisms to address issues such as component wear, making it difficult to guarantee consistently good ejection performance during long-term use.
[0005] To overcome the shortcomings of traditional caliper date mold ejection devices and improve the production efficiency and quality of caliper date molds, developing a caliper date mold ejection device with higher precision, better stability, and more convenient adjustment functions is of significant practical importance. This utility model of a caliper date mold ejection device was developed in this context, aiming to solve the problems existing in the prior art through innovative structural design and provide a more reliable ejection solution for the production of caliper date molds.

Detailed Implementation
[0033] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0034] like Figures 1 to 4 As shown in the figure, a caliper date mold ejection device provided by this utility model includes a limiting part 100, a first top plate 200, and a second top plate 300. The limiting part 100 is installed on the production equipment and sets the date mold to facilitate the date printing of the product by the date mold. The limiting part 100 is provided with a limiting groove 110 and a through hole 120. The first top plate 200 and the second top plate 300 are placed in the limiting groove 110. A support rod 400 is connected to one side of the first top plate 200 and moves through the through hole 120. A caliper date template 700 is provided at one end of the support rod 400 away from the first top plate 200. The caliper date template 700 can be moved easily by the support of the support rod 400.
[0035] Within the limiting groove 110, the first top plate 200 and the second top plate 300 are installed side by side, and the width of the limiting groove 110 is equal to the width of the first top plate 200 and the second top plate 300, so that the first top plate 200 and the second top plate 300 can move linearly within the limiting groove 110.
[0036] In this embodiment, the first top plate 200 and the second top plate 300 are connected in abutment.
[0037] A first fixing hole 210 is provided on the first top plate 200 at the position corresponding to the support rod 400. The first fixing hole 210 passes through both sides of the first top plate 200. The first fixing hole 210 is a circular fixing hole, and the support rod 400 is a cylindrical support rod 400. The first fixing hole 210 and the support rod 400 have the same radius, so that the first fixing hole 210 can effectively limit the support rod 400 and prevent the support rod 400 from shaking.
[0038] A second fixing hole 310 is provided on the second top plate 300 at the position corresponding to the first fixing hole 210. The depth of the second fixing hole 310 is less than the corresponding thickness of the second top plate 300, so that the end of the support rod 400 away from the date template 700 is located in the second fixing hole 310, which facilitates the second top plate 300 to push the support rod 400.
[0039] In this embodiment, a fixing groove 140 is provided on the limiting part 100 corresponding to the position of the date template 700. The date template 700 is embedded in the fixing groove 140, and the through hole 120 connects to the fixing groove 140, so that the date template 700 is connected to the support rod 400. In order to facilitate the ejection of the date template 700 in the fixing groove 140, a transverse groove 320 is provided on the second top plate 300. The transverse groove 320 is provided perpendicular to the direction of the support rod 400 and connects to the second fixing hole 310. An adjustment device 500 is provided in the transverse groove 320. The adjustment device 500 can eject the support rod 400, so that the support rod 400 can move in the first fixing hole 210 and the second fixing hole 310. After the support rod 400 is ejected by the adjustment device 500, the date template 700 is ejected in the fixing groove 140, which facilitates the replacement of the date template 700.
[0040] The adjusting device 500 is mainly equipped with an adjusting rod 510, which is movably disposed in the transverse groove 320, and one end of the adjusting rod 510 extends into the second fixing hole 310. When the adjusting rod 510 moves in the transverse groove 320, it can push out the support rod 400.
[0041] To facilitate the movement of the adjusting rod 510 within the transverse groove 320, a transition surface 512 is provided at one end of the adjusting rod 510. The transition surface 512 is obliquely arranged so that when the adjusting rod 510 is moved within the transverse groove 320, the support rod 400 moves through the transition surface 512, thus facilitating the adjustment rod 510 to support the support rod 400.
[0042] In this embodiment, an abutment device 600 is provided on the adjusting rod 510 at the position corresponding to the second fixing hole 310. The abutment device 600 can abut against the support rod 400, making the support rod 400 more stable during movement. The abutment device 600 mainly includes an abutment block 610 and an abutment spring 620. An abutment groove 511 is formed on the adjusting rod 510 at the position corresponding to the abutment block 610 and the abutment spring 620. The abutment spring 620 and the abutment block 610 are located in the abutment groove 511 on the adjusting rod 510. The abutment block 610 is located at the end of the abutment spring 620 away from the abutment groove 511. When the adjusting rod 510 moves in the transverse groove 320, the abutment block 610 can abut against the support rod 400. Through the elastic force of the abutment spring 620, the abutment block 610 always maintains contact with the support rod 400, which facilitates the adjusting rod 510 to push the support rod 400.
[0043] In this application, a fixing screw is provided on the adjusting rod 510. When the adjusting rod 510 moves to a certain position, the fixing screw is rotated. The fixing screw is connected to the second top plate 300, so that the adjusting rod 510 is fixed on the second top plate 300.
[0044] Preferably, in this embodiment of the application, the end of the abutment block 610 that contacts the support rod 400 may be provided with a concave arc surface, the curvature of which matches the outer circumference of the support rod 400, so that the contact area between the abutment block 610 and the support rod 400 is larger and the abutment is more stable.
[0045] On the second top plate 300, a slope 330 is formed at one end of the second fixing hole 310 facing the transverse groove 320. The slope 330 connects the transverse groove 320 and the second fixing hole 310. When the adjusting rod 510 moves to a certain position within the transverse groove 320, the abutment block 610 abuts against the slope 330. Through the guiding effect of the slope 330, the abutment block 610 can enter the second fixing hole 310 more smoothly and abut against the support rod 400. In this embodiment, the inclination angle of the slope 330 is 45°. This angle allows the abutment block 610 to move more smoothly during the process, while ensuring that the abutment force of the abutment block 610 against the support rod 400 is moderate.
[0046] A reset spring assembly 130 is also provided at the bottom of the limiting groove 110. The two ends of the reset spring assembly 130 are respectively connected to the bottom of the limiting groove 110 and the surface of the first top plate 200. The first top plate 200 and the second top plate 300 can be pushed by the action of the spring. The first top plate 200 and the second top plate 300 drive the support rod 400 to embed the date template 700 into the fixing groove 140.
[0047] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
