Description

Technical Field

[0001] This utility model relates to the field of horizontal mold clamping machines, and more particularly to a horizontal mold clamping machine with adjustable tensile strength and balance. Background Technology

[0002] Horizontal mold clamping machines are mainly used in the following fields: 1. Mold manufacturing: In the process of preparing and fitting large and heavy molds, horizontal mold clamping machines can achieve high-precision positioning and improve the mold fitting accuracy due to their strong anti-eccentric load capacity and stable structure; 2. Industrial production: In the automotive, electronic equipment and other manufacturing industries, horizontal mold clamping machines are often used for deep cavity processing of body molds and precision electronic molds to ensure product dimensional accuracy and stability; 3. Automated production: Some companies integrate horizontal mold clamping machines into automated production lines to achieve continuous processing, which is suitable for the mass production of automotive parts (such as crankshafts and connecting rods).

[0003] Traditional horizontal mold clamping machines are divided into two types: one uses a C-shaped frame with a 45-degree inclined guide rail, which has poor resistance to eccentric loads and is gradually becoming unsuitable for modern precision molds; the other uses a four-Grinding column guide structure, which is not suitable for large-tonnage horizontal mold clamping machines, and produces a lot of iron dust during mold repair. Iron dust entering the Grinding column guide area can easily damage the Grinding columns, increase the gap between the guide rail and the slide, and cause the slide to slide on the guide rail to easily shift laterally, resulting in reduced accuracy of the two molds being joined and affecting the stability of the mold clamping. Summary of the Invention

[0009] Specifically, the first sliding assembly includes a slide block, a longitudinal pad, and a transverse pad. The slide block is mounted on the side of the slide table.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. Its mold closing action structure adopts a structure similar to that of an injection molding machine, which has high mold closing accuracy and realistic mold closing red lead effect.

[0016] 2. As more and more high-end molds are being produced, more and more mold workshops are becoming air-conditioned workshops. Their horizontal mold-closing structure does not require excessive installation space, thereby reducing the need for cooling space and saving electricity costs.

[0017] 3. This new type of horizontal mold clamping machine adopts 90-degree right-angle guide rails. Each guide rail can be freely adjusted up, down, left, and right. The vertical positioning and adjustment of the guide rails are achieved by relying on the center of gravity of the mold. It has the advantages of high mold clamping accuracy, good stability, high efficiency, and strong mold locking ability. Both its anti-eccentric load capacity and mold clamping accuracy are a level higher than those of traditional mold clamping machines. It solves the problem that traditional mold clamping machines are prone to lateral displacement or offset on the guide rails when the gap between the guide rail and the slide table becomes larger, which can easily lead to low mold clamping accuracy, poor mold clamping stability, and poor mold clamping effect.

[0018] 4. It adopts a 90-degree right-angle guide rail and is supported by four connecting columns to bear the tension of the mold closing. The four connecting columns are adjusted for flatness of the mold closing frame by adjusting nuts and locking nuts installed on them, which improves the shortcomings of the mold closing frame of the previous model, such as unevenness and poor torsional and tensile resistance. It optimizes the entire equipment and makes the whole equipment more suitable for the needs of modern mold making. It promotes the realization of precise mold closing and locking of large-tonnage horizontal mold closing machines, and effectively solves the problem of poor anti-eccentric load capacity of traditional mold closing machines.

[0039] Reference Figure 8 As shown, the first locking assembly 314 includes a guide seat 3141, a lock seat 3142, a locking pin 3143, and a locking pin telescopic drive device 3144. The lock seat 3142 is disposed on one side of the guide seat 3141, and the locking pin telescopic drive device 3144 is mounted on the other side of the guide seat 3141.

[0040] Reference Figure 4 and Figure 8As shown, the structure and working principle of the second locking component 326 are the same as those of the first locking component 314. The guide seat 3141 of the first locking component 314 is installed on the bottom surface of the slide table 310, and the lock seat 3142 of the first locking component 314 is installed on the side of the bottom of the first tilting table 312 facing the slide table 310.

[0041] By adopting the above technical solution, the locking pin telescopic drive device 3144 drives the locking pin 3143 to pass through the guide seat 3141 and insert into the locking seat 3142.

[0042] In this embodiment, the locking pin extension and retraction drive device 3144 is preferably configured as a cylinder.

[0043] Reference Figure 9 As shown, the first sliding assembly 41 includes a slide block 411, a longitudinal washer 412, and a transverse washer 413. The slide block 411 is mounted on the side of the slide table 310. A groove 414 is recessed into the slide table 310 on one side of the bottom of the slide block 411.

The longitudinal washer 412 and the transverse washer 413 are arranged perpendicular to each other. The structure of the second sliding assembly 42 is mirror-symmetrical to the structure of the first sliding assembly 41.

[0044] Reference Figure 9As shown, the first sliding adjustment mechanism 21 includes a beam frame 211, a transverse adjusting bolt 212, a longitudinal adjusting bolt 213, and a guide rail 214. The beam frame 211 is mounted on the same side of the first flip base 5 and the second flip base 320. The transverse adjusting bolt 212 is transversely screwed onto the beam frame 211 and is rotatably connected to one side of the guide rail 214. The longitudinal adjusting bolt 213 is longitudinally screwed onto the beam frame 211 and is rotatably connected to the bottom of the guide rail 214. There are one or more transverse adjusting bolts 212 and one or more longitudinal adjusting bolts 213. The structure of the second sliding adjustment mechanism 22 is mirror-symmetrical to the structure of the first sliding adjustment mechanism 21.

[0045] Reference Figure 2 , Figure 3 and Figure 9 As shown, by adopting the above technical solution, the top surface of the guide rail 214 is opposite to and parallel to the transverse shim 413, and one side of the guide rail 214 is opposite to and parallel to the longitudinal shim 412. The slide block 411 slides on the guide rail 214 (i.e., the 90-degree right-angle guide rail) through the longitudinal shim 412 and the transverse shim 413. The fit and parallelism between the side of the guide rail 214 and the longitudinal shim 412 are adjusted by adjusting the transverse adjusting bolt 212 on the beam frame 211, and the fit and parallelism between the top surface of the guide rail 214 and the transverse shim 413 are adjusted by adjusting the longitudinal adjusting bolt 213 on the beam frame 211. By adjusting the sliding support of the first mold-flipping mechanism 31 through the first sliding adjustment mechanism 21 and the second sliding adjustment mechanism 22, the first mold-flipping mechanism 31 slides smoothly and stably on the guide rails 214 of the first sliding adjustment mechanism 21 and the second sliding adjustment mechanism 22. This improves the smoothness, accuracy and stability of the mold closing of the first mold-flipping mechanism 31 and the second mold-flipping mechanism 32. This solves the problem that after long-term use of traditional mold-closing machines, the gap between the guide rail and the slide table becomes larger and cannot be adjusted due to damage to the Green Column, which easily causes the slide table to shift or deviate on the guide rail, resulting in poor mold closing accuracy and poor mold closing stability of the two molds.

[0046] Reference Figure 1 As shown, there are two or more connecting posts 6. One end of the connecting post 6 is threaded with a first adjusting nut 9 and a first locking nut 10, and the other end of the connecting post 6 is threaded with a second adjusting nut 11 and a second locking nut 12. The first locking nut 10 is located on the side of the first flip base 5 facing away from the second flip base 320. The first adjusting nut 9 and the second adjusting nut 11 are located between the first flip base 5 and the second flip base 320. The second locking nut 12 is located on the side of the second flip base 320 facing away from the first flip base 5.

[0047] By adopting the above technical solution, by adjusting the position of the first adjusting nut 9 and the second adjusting nut 11 on the connecting column 6, two or more connecting columns 6 are perpendicular to the first flip base 5 and the second flip base 320 respectively, so that the first flip base 5 and the second flip base 320 remain relatively parallel. The frame composed of the first flip base 5, the second flip base 320 and the two or more connecting columns 6 has good rigidity. When the first flipping mechanism 31 and the second flipping mechanism 32 close the mold, the frame composed of the first flip base 5, the second flip base 320 and the two or more connecting columns 6 has the advantages of good tensile strength, high rigidity and high stability, making it particularly suitable for closing modern precision molds, thus solving the problem of poor anti-eccentric load capacity of the traditional mold closing machine with C-shaped structure frame and 45-degree inclined guide rail.

[0048] In this embodiment, four connecting posts 6 are preferably provided, and the four connecting posts 6 are respectively installed at the four opposite corners of the first flip base 5 and the second flip base 320.

[0049] Reference Figure 1 As shown, an electric motor 13 is provided on the outer side of one end of the base frame 1, and a control device 14 is installed on the second flip base 320.

[0050] By adopting the above technical solution, the electric motor 13 is used to increase the hydraulic oil pressure.

[0051] Reference Figure 1 As shown, the booster device 8 is connected to the slide translation drive device 7 via an oil pipe.

[0052] By adopting the above technical solution, the slide translation drive device 7 pushes the first mold-flipping mechanism 31 to move towards the second mold-flipping mechanism 32.
