Description

Technical Field

[0001] This utility model belongs to the field of machining positioning fixture technology, and particularly relates to a positioning fixture and a transverse movement module. Background Technology

[0002] In recent years, injection-molded products have been widely used in various industries. To enable products to have special mechanical joints or other functions, it is often necessary to embed hardware parts into molds and fix them through the injection molding process. However, deviations can easily occur during the placement of hardware parts into the mold, causing the already positioned hardware parts to shift, thus affecting the quality of the final injection-molded product. This problem is particularly prominent when dealing with small hardware parts such as ring-shaped hardware parts that have precise positioning requirements. The key to solving these problems lies in using a positioning fixture that can accurately fix the position of hardware parts, ensuring that each hardware part is accurately placed in the designated position within the mold.

[0003] In current injection molding processes, metal parts are placed directly into the mold manually or with the aid of robotic arms. While this method meets certain requirements, it still suffers from significant human error and limitations in robotic arm operation. Especially when the mold interior is confined or the metal parts have complex shapes, this direct placement method easily leads to deviations in the part's position, increasing the defect rate of the injection-molded product. Therefore, the industry has been exploring more precise and stable methods for positioning metal parts to improve the production efficiency and product quality of injection-molded products. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture and a transverse module, which aims to solve the technical problem that the direct placement of pre-embedded hardware parts during injection molding in the prior art easily leads to deviations in the placement of the hardware parts, increasing the defect rate of the injection molded products.

[0005] To achieve the above objectives, this utility model provides a positioning fixture and a lateral movement module, including a linear module and a mounting fixture. The mounting fixture is disposed at the drive end of the linear module, which drives the mounting fixture to move laterally to the loading or unloading position. The mounting fixture is used to position hardware parts. The mounting fixture includes a base, a mounting plate, several support columns, and several ejector pins. The base is connected to the linear module, and the mounting plate is located above the base. Each support column is connected at both ends to the top of the base and the bottom of the mounting plate, respectively, to support the mounting plate. Each ejector pin is disposed on the top of the mounting plate and is used to position the hardware parts.

[0006] Furthermore, the upper end of the ejector pin is designed as a cylindrical head.

[0007] Furthermore, each ejector pin is perpendicular to the mounting plate. Both the mounting plate and the base have connecting holes, through which each ejector pin passes and is slidably connected to both the mounting plate and the base. Each ejector pin also has a limiting ring, the diameter of which is larger than the diameter of the connecting hole. The limiting ring is positioned between the mounting plate and the base. A return spring is also included, sleeved on the ejector pin, with one end abutting the base and the other end abutting the limiting ring, used to drive the ejector pin upwards.

[0008] Furthermore, the mounting plate is also provided with several positioning rings, each positioning ring is fitted onto the ejector pin and fixedly connected to the mounting plate, and the top of the ejector pin extends out of the positioning ring.

[0009] Furthermore, a positioning hole is provided at the center of the mounting plate.

[0010] Furthermore, each ejector pin is set in two groups and is mirror-symmetrically arranged on the mounting plate.

[0011] Furthermore, the base includes a base plate and a slider, the slider being slidably mounted on the linear module, and the base plate being mounted on the slider.

[0012] Furthermore, the linear module is also equipped with a sensor, and a lever is also provided on one side of the slider. The sensor is used to detect the position of the lever.

[0013] The positioning fixture and lateral movement module provided in this embodiment of the utility model have at least one of the following technical effects: Ejector pins are set on the mounting plate according to the position of the hardware parts to be placed in the mold. A linear module drives the mounting fixture to the loading position, and then the hardware parts are inserted into the ejector pins for positioning. The linear module then drives the mounting fixture to the unloading position, and the robotic arm simultaneously removes the hardware parts from each ejector pin and places them in the mold. This mounting fixture not only pre-arranges the hardware parts to ensure their precise placement in the designated position within the mold, but also effectively avoids displacement of the hardware parts due to improper operation during placement. Furthermore, by using ejector pin positioning, production efficiency can be significantly improved, reducing manpower and machinery input, while also significantly reducing the scrap rate caused by hardware part position deviations during production, thereby greatly improving product quality and the company's economic benefits.

[0022] In one embodiment of this utility model, reference is made to Figures 1-2 As shown, a positioning fixture and a lateral movement module are provided, including a linear module 100 and a mounting fixture 200. The mounting fixture 200 is disposed at the drive end of the linear module 100. The linear module 100 is used to drive the mounting fixture 200 to move laterally to the loading or unloading position. The mounting fixture 200 is used to position hardware parts. The mounting fixture 200 includes a base 210, a mounting plate 220, several support columns 230, and several ejector pins 240. The base 210 is connected to the linear module 100. The mounting plate 220 is located above the base 210. The two ends of each support column 230 are respectively connected to the top end of the base 210 and the bottom end of the mounting plate 220 to support the mounting plate 220. Each ejector pin 240 is disposed on the top of the mounting plate 220 and is used to position hardware parts. In this embodiment, ejector pins 240 are positioned on the mounting plate 220 according to the location of the hardware parts to be placed in the mold. The linear module 100 drives the mounting fixture 200 to the loading position, and then the hardware parts are inserted into the ejector pins 240. The ejector pins 240 are used to position the hardware parts. Then, the linear module 100 drives the mounting fixture 200 to the unloading position, and the robotic arm simultaneously removes the hardware parts from each ejector pin 240 and places them into the mold. This mounting fixture 200 not only arranges the hardware parts in advance to ensure that they are accurately placed in the designated position in the mold, but also effectively avoids the displacement of the hardware parts caused by improper operation during the placement process. In addition, by using the ejector pins 240 for positioning, production efficiency can be greatly improved, labor and machinery input can be reduced, and the scrap rate caused by the positional deviation of the hardware parts during the production process can be significantly reduced, thereby greatly improving product quality and the economic benefits of the enterprise.

[0023] Specifically, refer to Figures 1-2 As shown, the upper end of the ejector pin 240 is cylindrical. In this embodiment, the cylindrical shape facilitates guidance, making it easier for hardware components to be inserted into the ejector pin 240.

[0024] Specifically, refer to Figures 1-2As shown, each ejector pin 240 is perpendicular to the mounting plate 220. Both the mounting plate 220 and the base 210 have connecting holes 250. Each ejector pin 240 passes through the connecting hole 250 and is slidably connected to the mounting plate 220 and the base 210. Each ejector pin 240 also has a limiting ring 241, the diameter of which is larger than the diameter of the connecting hole 250. The limiting ring 241 is positioned between the mounting plate 220 and the base 210. A return spring 242 is also included, sleeved on the ejector pin 240. One end of the return spring 242 abuts against the base 210, and the other end abuts against the limiting ring 241, used to drive the ejector pin 240 to move upwards. In this embodiment, when the robot arm is to remove the hardware from the mounting plate 220, one side of the robot arm should be provided with a pin 240 to abut against the pin 240, so that the pin 240 descends. Then, the picking cylinder clamps the hardware to avoid the friction between the hardware and the pin 240 affecting the picking cylinder when removing the hardware, which would cause the hardware to shift and thus affect the subsequent processing effect.

[0025] Specifically, refer to Figures 1-2 As shown, the mounting plate 220 is also provided with several positioning rings 221. Each positioning ring 221 is sleeved on the ejector pin 240 and fixedly connected to the mounting plate 220. The top of the ejector pin 240 extends out of the positioning ring 221. In this embodiment, the positioning ring 221 is used to support the hardware and raise the height of the hardware, making it convenient for the picking cylinder on the robotic arm to pick it up.

[0026] Specifically, refer to Figures 1-2 As shown, a positioning hole 222 is provided at the center of the mounting plate 220. In this embodiment, the positioning hole 222 is used to help the fixture on the robotic arm to be positioned so that each pick-up cylinder on the robotic arm can be aligned with the hardware on each ejector pin 240.

[0027] Specifically, refer to Figures 1-2 As shown, each ejector pin 240 is arranged in two groups and mirror-symmetrically on the mounting plate 220. In this embodiment, existing injection molds are generally arranged symmetrically on both sides, allowing the robot to place the hardware parts into the mold simultaneously in one go, eliminating the need for secondary placement and improving the accuracy of the hardware part's position.

[0028] Specifically, refer to Figures 1-2 As shown, the base 210 includes a base plate 211 and a slider 212. The slider 212 is slidably disposed on the linear module 100, and the base plate 211 is disposed on the slider 212. In this embodiment, the movement of the mounting fixture 200 is controlled by controlling the movement of the slider 212 through the linear mold.

[0029] Specifically, refer to Figures 1-2As shown, the linear module 100 is also equipped with a sensor 110, and a lever 213 is also provided on one side of the slider 212. The sensor 110 is used to sense the position of the lever 213. In this embodiment, the position of the mounting fixture 200 is located by sensing the position of the lever 213 through the sensor 110, thereby achieving precise loading and unloading.

[0030] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0031] 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 spirit and principles of the present utility model should be included within the protection scope of the present utility model.
