Description

Technical Field

[0001] This utility model relates to the field of watch manufacturing technology, and in particular to a fixture for placing iron sheets on a rubber watch strap. Background Technology

[0002] In watchmaking, particularly in the production of rubber watch straps, multiple thin metal sheets need to be pre-embedded into specific cavities of large molds. Further processing is then required to bond the sheets to the watch strap. Currently, this crucial loading process—placing the metal sheets into the mold cavities—is primarily done manually. Operators stand beside the large mold equipment, picking up individual metal sheets by hand, aligning them one by one, and placing them into the mold cavities. This traditional manual placement method is inefficient and inconvenient; therefore, a new solution is necessary to address these issues. Utility Model Content

[0003] In view of this, the present invention addresses the deficiencies of the prior art, and its main purpose is to provide a fixture for placing iron plates on rubber watch straps, which solves the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fixture for placing metal sheets in a rubber watch strap includes a template and a pin plate. The bottom surface of the template has multiple rows of metal sheet grooves, each row corresponding to a metal sheet required for one watch strap. Each metal sheet groove has a pin hole that extends vertically. The upper surface of the template has a first handle at both ends. The pin plate is mounted on the upper surface of the template and can move up and down. The pin plate has multiple pins, each of which passes through a pin hole to enter a metal sheet groove. A spring is provided between the pin plate and the template, causing the pin plate to always tend to move away from the template, so that the pins leave the metal sheet grooves. Both ends of the pin plate have vertically extending clearance holes, through which the first handles pass and can move up and down. The pin plate also has a second handle at each end, located beside the clearance holes.

[0006] As a preferred embodiment, each of the iron sheet grooves has two ejector pin holes, and correspondingly, the ejector pin plate is provided with two ejector pins for each iron sheet groove.

[0007] As a preferred embodiment, the template is provided with multiple vertically upward support columns, and correspondingly, the ejector plate is provided with multiple support column holes. The support columns pass through the support column holes and extend out of the upper surface of the ejector plate. The outer side wall of the part of the support column that extends out of the ejector plate has threads, and a nut is screwed into the threads to form a limit.

[0008] As a preferred embodiment, the bottom surface of the template is provided with a positioning protrusion that cooperates with and positions itself in conjunction with an external mold.

[0009] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0010] By using a template with multiple rows of slots for the metal sheets, the operator can pre-place all the metal sheets to be installed at once (this can be done conveniently from a distance from the mold). Then, the entire fixture is aligned with the mold cavity as a unit (because the metal sheets have a certain thickness and the slots are perfectly matched to the sheet dimensions, the sheets won't fall when the fixture flips downwards; they will be stuck in the slots). The operator then grasps the first and second handles, simultaneously pressing the second handle to depress the ejector plate. The ejector pins then push the entire batch of metal sheets out synchronously and into the mold cavity. This simplifies the previously tedious process of placing each sheet individually into a highly efficient batch operation, improving production efficiency.

[0011] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0021] Please see Figures 1 to 5 This utility model provides a fixture for placing metal pieces in a rubber watch strap, including a template 10 and a pin plate 20. The bottom surface of the template 10 is recessed with multiple rows of metal piece grooves 11, each row of metal piece grooves 11 corresponding to the metal pieces required for one watch strap. Each metal piece groove 11 has a pin hole 12 that passes through vertically. The upper surface of the template 10 is provided with first handles 30 at both ends. The pin plate 20 is disposed on the upper surface of the template 10 and can move up and down. The pin plate 20 is provided with multiple pins 21, each pin 21 corresponding to a front metal piece. The ejector pin 21 enters the iron plate groove 11 through the ejector pin hole 12. A spring 40 is provided between the ejector pin plate 20 and the template 10. The spring 40 causes the ejector pin plate 20 to always have a tendency to move away from the template 10, so that the ejector pin 21 leaves the iron plate groove 11. Both ends of the ejector pin plate 20 are provided with vertically penetrating clearance holes 22. The aforementioned first handle 30 passes through the clearance holes 22 and can move up and down in the clearance holes 22. In addition, both ends of the ejector pin plate 20 are also provided with second handles 50, which are located on the side of the clearance holes 22.

[0022] By using a template 10 with multiple rows of iron sheet grooves 11, the operator can pre-place all the iron sheets to be installed at once (this can be done conveniently from a distance from the mold). Then, the entire fixture is aligned with the mold cavity as a unit (because the iron sheets have a certain thickness and the dimensions of the iron sheet grooves 11 match the dimensions of the iron sheets, the iron sheets will not fall when the fixture is flipped downwards; they will be stuck in the iron sheet grooves 11). The operator then grasps the first handle 30 and the second handle 50, simultaneously pressing the second handle 50 to press down the ejector plate 20. The ejector pins 21 then simultaneously eject the entire batch of iron sheets and place them into the mold cavity. This simplifies the originally tedious process of placing each sheet individually into a highly efficient batch operation, improving production efficiency.

[0023] Furthermore, each of the aforementioned iron sheet grooves 11 has two ejector pin holes 12, and correspondingly, the ejector plate 20 has two ejector pins 21 for each iron sheet groove 11. By providing two ejector pin holes 12 and two corresponding ejector pins 21 in each iron sheet groove 11, each iron sheet can receive a balanced pushing force during ejection. This two-point symmetrical force application design effectively prevents the slender iron sheets from jamming, tilting, or flipping during ejection due to uneven force, ensuring that each iron sheet can be smoothly and steadily removed from the groove and fall into the mold cavity in the correct posture, further enhancing the stability and reliability of the placement process and providing a guarantee for high-precision assembly.

[0024] Furthermore, the template 10 is provided with multiple vertically upward-pointing support columns 60, and correspondingly, the ejector plate 20 is provided with multiple support column holes 23. The support column 60 passes upward through the support column holes 23 and extends out of the upper surface of the ejector plate 20. The outer side wall of the part of the support column 60 that extends out of the ejector plate 20 has threads, and a nut 70 is screwed into the threads to form a limit. Through the cooperation of the support column 60, the support column holes 23, and the nut 70, a guiding and limiting mechanism is constructed. The support column 60 not only provides reliable guidance for the up and down movement of the ejector plate 20 relative to the template 10, ensuring the perpendicularity of the movement trajectory of the ejector pin 21 and avoiding uneven wear or jamming between the ejector pin 21 and the ejector pin hole 12; but also, through the setting of the nut 70 at the top, limits the highest lifting position of the ejector plate 20, preventing the spring 40 from excessively rebounding and causing the ejector plate 20 to detach from the template 10.

[0025] Furthermore, the bottom surface of the template 10 is provided with a positioning protrusion 13 that cooperates with and positions the external mold. By providing the positioning protrusion 13 on the bottom surface of the template 10, the fixture can achieve rapid and accurate positioning when it cooperates with the external mold.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
