Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and specifically to a guide device for precision molds. Background Technology

[0002] A guide device for precision molds refers to a device specifically designed for use in precision molds to ensure that the mold can be accurately aligned and operate stably during mold closing, mold opening, stamping and other processes, and to protect the mold and stamping equipment. This guide device plays a vital role in mold manufacturing and stamping processes. It can improve the accuracy, stability and service life of the mold, while reducing production and maintenance costs.

[0003] A search revealed that Chinese utility model patent CN213919357U discloses an injection mold guiding device. This device uses a slider and guide rod for sliding connection, allowing the moving mold to slide up and down in a certain direction. This significantly reduces the likelihood of the moving mold deviating from the fixed mold during mold closing. Furthermore, a first buffer spring provides vertical cushioning. A falling insert plate into a slot causes two buffer blocks to move in a separating direction, compressing the second buffer spring and further reducing the impact force between the moving and fixed molds during mold closing, thus extending the equipment's lifespan.

[0004] However, in actual use, the continuous mold injection and repeated contact and friction between the guide post and the guide groove can easily cause the guide post to deform due to friction, affecting the accuracy of mold alignment and shortening the service life of the guide post. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a guide device for precision molds, which can effectively solve the problem of repeated docking and friction between the guide post and the guide groove, resulting in a shortened service life of the guide post.

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

[0007] This utility model provides a guiding device for precision molds, including an upper module and a lower module. The lower module is disposed below the upper module. A guide post is fixedly installed on the lower surface of the upper module. A mold cavity and a guide groove are formed on the upper surface of the lower module. An extrusion component is disposed inside the guide groove. The guide groove is connected to a transfer pipe. The transfer pipe is connected to a cavity. A first control component is disposed at one end of the transfer pipe near the upper module. The first control component includes a first spring fixedly installed on the transfer pipe. The first spring is fixedly connected to a first rotating block. The first rotating block is rotatably connected to the transfer pipe. An oil injection pipe is connected to the cavity. A second control component is disposed inside the oil injection pipe.

[0008] Furthermore, the guide grooves are provided in two sets and are symmetrically arranged, and the guide grooves are slidably connected to guide columns.

[0009] Furthermore, the extrusion assembly includes an extrusion plug slidably mounted on a guide groove, with one end of an extrusion spring fixedly connected above the extrusion plug, and the other end of the extrusion spring fixedly mounted on the lower surface of the slider.

[0010] Furthermore, the guide groove is symmetrically provided with sliding grooves inside, and the sliding grooves are slidably connected to sliders.

[0011] Furthermore, the second control component includes a second rotating plate rotatably mounted on the oil injection pipe, one end of the second rotating plate being fixedly connected to a second spring, and the other end of the second spring being fixedly mounted on the inner wall of the oil injection pipe.

[0012] Furthermore, the end of the oil injection pipe furthest from the extrusion assembly is connected to an oil storage chamber, and the oil injection pipe is inclined with the end closer to the oil storage chamber being lower.

[0013] Furthermore, an oil tank door is provided on the side of the upper module, and an oil storage cavity is provided on the back of the oil tank door.

[0014] Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] I. This utility model effectively reduces the direct friction between the guide post and the guide groove through the extrusion assembly, transfer pipe, first control assembly and cavity structure. During the molding process, the guide post transmits pressure to the extrusion assembly, thereby compressing the space in the cavity, so that the lubricant can smoothly enter the guide groove and provide lubrication for the guide post. This not only reduces the friction between the guide post and the guide groove, but also extends the service life of the guide post and reduces the maintenance and replacement cost of the mold.

[0017] Second, this utility model uses two sets of guide grooves arranged symmetrically to form a stable sliding connection with the guide pillars. This design enhances the fit stability between the upper and lower modules, ensuring the accuracy and stability of the mold during the pressing process, thereby improving the quality and consistency of the product. In addition, the ingenious design of components such as the extrusion spring and slider allows the extrusion components to quickly return to their initial state after the pressure is released, preparing for the next pressing, further improving the working efficiency and stability of the mold.

[0018] Third, this utility model achieves the saving and efficient use of lubricant through the synergistic effect of the first control component and the second control component. During the molding process, the lubricant is squeezed into the guide groove to provide lubrication for the guide post. After the pressure is released, the first spring and the second spring and other components can quickly reset to prevent excessive lubricant outflow. In addition, the design of the oil storage cavity and the oil injection pipe allows the lubricant to be easily replenished into the cavity, ensuring the continuous and stable lubrication effect. This design not only saves the amount of lubricant used, but also improves the lubrication effect and reduces production costs. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a guide device for precision molds, including an upper module 1 and a lower module 2. A guide post 3 is fixedly installed on the lower surface of the upper module 1. The lower module 2 is located below the upper module 1. A mold cavity 5 and a guide groove 4 are opened on the upper surface of the lower module 2. An extrusion component is installed inside the guide groove 4. The guide groove 4 is connected to a transfer pipe 17. The transfer pipe 17 is connected to a cavity 10. A first control component is installed at one end of the transfer pipe 17 near the upper module 1. The first control component includes a first spring 15 fixedly installed on the transfer pipe 17. The first spring 15 is fixedly connected to a first rotating block 16. The first rotating block 16 is rotatably connected to the transfer pipe 17. The cavity 10 is connected to an oil injection pipe 9. A second control component is installed inside the oil injection pipe 9.

[0029] The working principle of the precision mold guiding device proposed in this utility model is as follows: the raw material is placed into the mold cavity 5, and then the upper module 1 is squeezed to make the upper module 1 and the lower module 2 fit together completely, so that the guide post 3 can smoothly enter the guide groove 4 opened on the surface of the lower module 2 to complete one molding. During this process, the guide post 3 transmits pressure to the extrusion assembly. The extrusion assembly compresses the space inside the cavity 10. Under the continuous pressure, the lubricant inside the cavity 10 will flow along the transfer pipe 17 and squeeze the first rotating block 16 in the first control assembly. The first rotating block 16 rotates in the direction of the extrusion assembly, so that the first rotating block 16 pulls the first spring 15. When the pressing assembly is released, the first spring 15 will quickly drive the first rotating block 16 to reset, thereby sealing the transfer pipe 17 and preventing excessive lubricant from flowing out. This not only provides lubrication for the guide post 3, but also saves resources to a certain extent.

[0030] In one embodiment, the guide groove 4 is provided in two sets and is symmetrically arranged, and the guide groove 4 is slidably connected to the guide post 3.

[0031] The working principle of the precision mold guiding device proposed in this utility model is that two sets of symmetrically arranged guide grooves 4 provide stability for the fit between the upper module 1 and the lower module 2, and the sliding connection between the guide post 3 and the guide groove 4 further improves the stability between the upper module 1 and the lower module 2, effectively improving the quality of the product.

[0032] In one embodiment, the extrusion assembly includes an extrusion plug 11 slidably mounted on the guide groove 4, one end of an extrusion spring 13 is fixedly connected above the extrusion plug 11, and the other end of the extrusion spring 13 is fixedly mounted on the lower surface of the slider 14.

[0033] In one embodiment, for the guide groove 4, a sliding groove 12 is symmetrically provided inside the guide groove 4, and a slider 14 is slidably connected to the sliding groove 12.

[0034] The working principle of the guide device for precision mold proposed in this utility model is as follows: when the pressure on the upper module 1 is released, the compression spring 13 will push the slider 14 to slide stably in the slide groove 12. At the same time, the compression spring 13 will also pull the compression plug 11 to move upward, so that the space of the cavity 10 returns to its original size, preparing for the next molding, thus improving the overall working efficiency of the device.

[0035] In one embodiment, the second control component includes a second rotating plate 8 rotatably mounted on the oil injection pipe 9, one end of the second rotating plate 8 being fixedly connected to a second spring 7, and the other end of the second spring 7 being fixedly mounted on the inner wall of the oil injection pipe 9.

[0036] In one embodiment, for the oil injection pipe 9, the end of the oil injection pipe 9 away from the extrusion assembly is connected to the oil storage chamber 18, and the oil injection pipe 9 is inclined and the end near the oil storage chamber 18 is lower.

[0037] In one embodiment, for the upper module 1 described above, an oil tank door 6 is provided on the side of the upper module 1, and an oil storage chamber 18 is provided on the back of the oil tank door 6.

[0038] The working principle of the precision mold guiding device proposed in this utility model is as follows: when the upper module 1 presses the lower module 2 close together, the airflow in the cavity 10 will squeeze the second rotating plate 8, the second rotating plate 8 will pull the second spring 7, and the oil injection pipe 9 will be opened. Due to the gravity of the lubricant itself, there is a force on the second rotating plate in the direction of the pressing component, thereby avoiding the problem of excessive rotation of the second rotating plate and avoiding excessive flow of lubricant. The lubricant in the oil storage cavity 18 will smoothly enter the cavity 10 along the extension direction of the oil injection pipe 9, and replenish the missing lubricant in the cavity 10 in time.

[0039] It is worth noting that when the lubricant needs to be replenished, simply open the oil reservoir door 6 to replenish the lubricant in the oil storage chamber 18.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
