Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molding processing, in particular to an injection molding gate punching device. Background Art
[0002] In the field of optical communications, optical modules are key components, and their performance and quality directly affect the stability and efficiency of the entire communication system. The injection molded handle in the optical module is a connecting and supporting component, and is usually manufactured using the injection molding process during the production process. Although the injection molding process has the advantages of high production efficiency and low cost, during the molding process, in order to ensure that the injection molded part can be smoothly ejected from the mold, a gate is usually designed on the injection molded part. The gate is a small channel connecting the injection molded part to the runner. It guides the molten plastic into the mold cavity during the injection molding process. However, after the injection molded part is molded, the gate part becomes redundant material and needs to be removed to ensure the appearance and functional integrity of the product.
[0003] Traditional manual or semi-automatic methods of removing gates from injection molded parts have many shortcomings, such as low efficiency, high labor intensity, and difficult to control precision. Especially for small, high-precision parts such as injection molded handles for optical modules, manual punching is not only time-consuming and labor-intensive, but also easily leads to part damage or uneven punching, affecting product quality.

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0025] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.
[0026] like Figure 1 and Figure 2 As shown, a gate punching device for injection molding parts of the present utility model comprises a punching table 1 and a top frame 2 mounted on the punching table 1;
[0027] The punching table 1 is provided with a material seat 3, and a punching bottom die 4 is installed on the material seat 3. A plurality of equally spaced injection molding placement grooves 4.1 are reserved on the punching bottom die 4, and a punching edge 4.2 is reserved along one side of the notch of the injection molding placement groove 4.1; a discharge port 3.1 is opened on the material seat 3 and is located below the punching edge 4.2;
[0028] The top frame 2 is provided with a pressing plate 5 and a cylinder 6 connected to the pressing plate 5 ; a cutter 5 . 1 matching the punching edge 4 . 2 of the punching bottom die 4 is provided below the pressing plate 5 .
[0029] The equipment is mainly composed of a punching table 1 and a top frame 2, forming a punching structure corresponding to the upper and lower parts. On the punching table 1, there is a material holder 3, on which a punching bottom die 4 is fixed. The punching bottom die 4 is designed with a plurality of equally spaced injection molded part placement grooves 4.1 for placing the injection molded parts to be punched, and a punching edge 4.2 is reserved on one side of each placement groove 4.1, which is for the subsequent punching of the gate part on the injection molded part. The material holder 3 is also provided with a discharge port 3.1 below the punching edge 4.2, which is used to discharge the waste material punched out.
[0030] When the injection molded part is placed in the injection molded part placement groove 4.1 of the punching bottom mold 4 and positioned, the cylinder 6 drives the pressing plate 5 and the cutter 5.1 below it to move downward until the cutter 5.1 contacts the gate part on the injection molded part and the punching is completed. The punched waste is discharged through the discharge port 3.1 below the punching edge 4.2, and the punched injection molded part remains in the placement groove 4.1, waiting for subsequent removal or further processing.
[0031] By processing multiple injection molded parts in parallel, the production efficiency of the equipment is significantly improved. Compared with the method of punching single slots one by one, punching multiple slots at the same time can greatly shorten the production cycle and speed up the product off the line.
[0032] The entire punching process is automated, which improves production efficiency. At the same time, the precise matching of the cutter 5.1 and the punching edge 4.2 ensures the punching accuracy and the quality of the injection molded parts.
[0033] As an embodiment, the punching bottom mold 4 is also provided with a pressing plate 7 covering the rear end of the injection molded part placement groove 4.1. The main function of the pressing plate 7 is to fix the injection molded part during the punching process to prevent it from moving or deforming during the punching process. By covering and pressing the rear end of the injection molded part with the pressing plate 7, it can be ensured that the injection molded part maintains a stable position and shape during the punching process, thereby improving the punching accuracy.
[0034] As an embodiment, the punching table 1 is also equipped with a plurality of elastic support members 8 connected to the material holder 3, and a limiter 9 for limiting the telescopic distance of the material holder 3. The function of the limiter 9 is to limit the telescopic distance of the material holder 3 under the action of the elastic support member 8. This is to prevent the material holder 3 from excessively displacing when subjected to excessive punching force, resulting in damage to the injection molded part, mold collision or equipment failure.
[0035] Specifically, the elastic support member 8 includes a guide rod 8.1 that is slidably matched with the material seat 3 and a spring 8.2 that is sleeved outside the guide rod 8.1.
[0036] The elastic support member 8 is mainly composed of a guide rod 8.1 that is slidably matched with the material holder 3 and a spring 8.2 that is sleeved on the guide rod 8.1. During the punching process, when the cutter 5.1 applies a punching force to the injection molded part, the material holder 3 may be subjected to a reaction force and produce a small vibration or displacement. As an elastic element, the spring 8.2 can effectively absorb and buffer these vibrations and displacements, reducing their impact on the overall stability and accuracy of the equipment.
[0037] As an embodiment, the punching station 1 is further provided with a guide slope 10 located below the discharge opening 3.1.
[0038] A waste collection box 11 is also provided along the bottom end of the material guiding slope 10 .
[0039] The guide slope 10 is located below the discharge port 3.1, and its main function is to guide the waste generated during the punching process, such as the gate part of the injection molded part, to flow out smoothly. Through the inclined slope design, the waste can automatically slide down under the action of gravity, avoiding the accumulation and retention of waste on the punching table 1. The waste collection box 11 can accommodate a certain amount of waste, avoiding the need for frequent replacement or cleaning.
[0040] As an embodiment, a plurality of slide bars 12 are provided between the top frame 2 and the punching table 1, which are slidably matched with the pressing plate 5. The slide bars 12 serve as guide elements for the pressing plate 5 in the vertical direction, ensuring that the pressing plate 5 can move up and down smoothly and accurately under the drive of the cylinder 6. This guiding effect avoids the unstable phenomena such as deviation, shaking or tilting of the pressing plate 5 during the movement, thereby ensuring the accuracy and stability of the punching process.
[0041] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.
