Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to an energy-saving injection mold with a mold closing guide structure. Background Technology

[0002] In the injection molding process, molds achieve precise mold closing through specific guiding devices, improving the stability and accuracy of mold closing between the core and cavity, and avoiding misalignment. However, during use, prolonged operation and the operation of large molds can easily cause slight misalignment of the guiding mechanism during mold closing, affecting the accuracy of mold closing between the core and cavity.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN202121425725.7, application date 20210625) provides an energy-saving injection mold with a mold closing guide structure. By setting an oil injection mechanism inside the guide pillar, lubricating oil can be injected between the locking block and the slide groove, so that the sleeve has good lubrication when sliding on the surface of the guide pillar, reducing friction between them and facilitating precise mold closing between the upper and lower mold bases. At the same time, excess lubricating oil can flow into the collection cylinder along the slide groove, and after filtration, it can be easily recycled for subsequent use, thus playing an energy-saving role. Although the prior art can complete the guiding and lubrication functions, during operation, the guide mechanism is prone to insufficient lubrication after long-term operation, which affects the accuracy of the guide rod limit and is prone to wear on the guide rod, affecting the use effect of the mold closing guide mechanism. Furthermore, it is not easy to control the uniform distribution of lubricating oil, which affects the lubrication effect.

[0004] To address the aforementioned issues, there is an urgent need for innovative design of energy-saving injection molds based on the existing mold closing and guiding structure. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: an energy-saving injection mold with a mold closing guide structure, comprising a front mold frame 1 and a rear mold frame 2 for mold closing and docking, wherein a guide rod 3 is nested and assembled on the inner surface of the front mold frame 1.

[0026] Example 1: As Figures 1-4 The technical solution shown in this utility model provides the following technical solution: an energy-saving injection mold with a mold closing guide structure, comprising: a copper sleeve 4 nested on the outer surface of a guide rod 3, a sealing plate 5 nested on the inner surface of a rear mold frame 2, an extrusion rod 6 telescopically connected to the inner surface of the rear mold frame 2, an extrusion cavity 7 nested on the lower side of the outer surface of the extrusion rod 6, and a return spring 8 elastically connected between the extrusion rod 6 and the rear mold frame 2, while the extrusion cavity 7 is provided with a pneumatic drive mechanism; Figure 4 As shown, the copper sleeve 4 and the guide rod 3 form a nested structure, and the rear mold frame 2 and the sealing plate 5 form an embedded structure. Furthermore, the rear mold frame 2 and the extrusion rod 6 form an elastic sliding structure via the return spring 8, while the extrusion rod 6 and the extrusion chamber 7 form an extrusion structure. Figure 4 As shown, the pneumatic drive mechanism includes an exhaust pipe 9 mounted on the upper and lower sides of the outer surface of the extrusion chamber 7, a drive member 10 mounted on the outer surface of the exhaust pipe 9, and a turbine 11 rotatably connected to the inner surface of the drive member 10. Simultaneously, an exhaust pipe 12 is mounted on the front side of the outer surface of the drive member 10, and the exhaust pipe 12 passes through the inner surface of the sealing plate 5. Figure 4As shown, the extrusion chamber 7 forms an air pump structure with the air outlet pipe 9 through a one-way air inlet valve, and the air outlet pipe 9, the drive component 10, and the exhaust pipe 12 form an integrated structure. The drive component 10 and the turbine 11 form a rotating structure, and the exhaust pipe 12 and the sealing plate 5 form a through structure.

[0027] In use, the front mold frame 1 and the rear mold frame 2 are controlled to close the mold. During the mold closing process, the guide rod 3, which is nested in the front mold frame 1, is used to position the externally nested copper sleeve 4. The movement of the rear mold frame 2 controls the internal copper sleeve 20 to engage with the copper sleeve 4 assembled with the guide rod 3. Both the contact surfaces of the copper sleeve 4 and the copper sleeve 20 are provided with tapered surfaces to improve the accuracy of the engagement. Ball bearings are nested on the copper sleeve 4 to improve lubrication during engagement with the copper sleeve 20. During the mold closing process between the front mold frame 1 and the rear mold frame 2, the movement of the rear mold frame 2 will cause the extrusion rod 6 to contact the front mold frame 1, and the extrusion rod 6 will be pressed during the extrusion process. The compression chamber 7 contracts and squeezes the air inside, controlling the air supply to the exhaust pipe 9. The gas flows to the drive component 10 assembled in the exhaust pipe 9, which drives the turbine 11 assembled in the drive component 10 to rotate. This allows the incoming air to be discharged through the exhaust pipe 12 assembled in the drive component 10, thereby controlling the stability of the turbine 11's rotation in the drive component 10. When the mold is separated between the front mold frame 1 and the rear mold frame 2, the extrusion rod 6 is reset by the elasticity of the return spring 8. This controls the air intake of the extrusion chamber 7 in conjunction with the one-way air intake valve, and the exhaust pipe 12 assembled in the extrusion chamber 7 is also equipped with a one-way valve for air discharge, improving the stability of the cooperation between the extrusion rod 6 and the extrusion chamber 7.

[0028] Example 2: Figure 4 and Figure 5 The technical solution shown, based on Embodiment 1, further discloses the lubrication component 13 for discharging lubricating oil, improving the lubricating oil output effect and solving the problem of lubricating oil being difficult to deliver in real time. Its specific content is as follows: The lubrication component 13 is nested and connected to the inner surface of the rear mold frame 2, and a drive component 10 is installed on the upper side of the outer surface of the lubrication component 13. The drive component 10 is rotatably connected to a threaded rod 14 via a turbine 11. Simultaneously, the lubrication component 13 is threadedly connected to an extrusion plate 15 via the threaded rod 14, and the lubrication component 13 is equipped with an extrusion lubrication mechanism; Figure 4 and Figure 5 As shown, the lubrication component 13 and the rear mold frame 2 form an embedded structure, and the lubrication component 13 and the drive component 10 form an integrated structure. The drive component 10 forms a rotating structure with the turbine 11 and the threaded rod 14, while the lubrication component 13 forms a threaded extrusion structure with the extrusion plate 15 through the threaded rod 14.

[0029] When the turbine 11 assembled in the drive component 10 rotates, it drives the threaded rod 14 assembled in the lubrication component 13 to rotate, thereby controlling the threaded rod 14 to drive the extrusion plate 15 to slide in the lubrication component 13, causing the oil delivery pipe 16 assembled in the lubrication component 13 to deliver lubricating oil to the oil distribution component 17, thereby improving the oil delivery effect.

[0030] Example 3: Figure 5 and Figure 6 The technical solution shown, based on Embodiment 2, further discloses that the oil distributor 17 works in conjunction with the copper sleeve 20 for oil delivery, improving the oil delivery and lubrication effect and solving the problem of uneven oil distribution. The specific details are as follows: The extrusion lubrication mechanism includes an oil delivery pipe 16 mounted on the lower surface of the lubrication assembly 13, and an oil distributor 17 is mounted on the lower surface of the oil delivery pipe 16. The oil distributor 17 is nested in the rear die frame 2, and the oil distributor 17 is nested in the inner surface of the rear die frame 2 by a limiting block 18. A through hole 19 is provided on the inner surface of the oil distributor 17, and the copper sleeve 20 is nested and connected to the inner surface of the oil distributor 17. A positioning element 21 is connected to the outer surface of the copper sleeve 20, and the copper sleeve 20 is fixedly assembled inside the rear die frame 2. Figure 5 and Figure 6 The lubrication assembly 13 shown forms an oil supply structure with the oil distribution component 17 via the oil supply pipe 16. The oil distribution component 17 forms a nested structure with the rear mold frame 2 via the limiting block 18. The oil distribution component 17 forms an oil inlet structure with the copper sleeve 20 via the through hole 19. At the same time, the copper sleeve 20 forms a limiting extrusion structure with the rear mold frame 2 via the positioning component 21.

[0031] When the lubrication component 13 controls the lubricating oil to be delivered from the oil supply pipe 16 to the oil distribution component 17, the through hole 19 of the control oil distribution component 17 is aligned with the through hole 19 of the copper sleeve 20, and the oil is delivered to the inside of the copper sleeve 20, thereby improving the lubrication effect between the copper sleeve 20 and the through-assembled copper sleeve 4. In addition, the limiting block 18 installed in the oil distribution component 17 is stably nested in the rear mold frame 2, thereby improving the stability of the assembly of the oil distribution component 17. Furthermore, in conjunction with the use of the positioning component 21 and the rear mold frame 2, the stability of the assembly between the oil distribution component 17 and the copper sleeve 20 is increased, preventing detachment.
