Description

Technical Field

[0001] This invention relates to a molding machine, and more particularly to a hot press molding machine. Background Technology

[0002] See Figure 1 The existing hot press molding machine 1 includes a machine base 11, a mold flipping device 12 pivotally mounted on the machine base 11, an upper mold device 13 mounted on the mold flipping device 12, and a bottom mold device 14 mounted on the machine base 11. The machine base 11 has a base 111 for mounting the bottom mold device 14 and two support frames 112 for mounting the mold flipping device 12. Each support frame 112 is provided with a pivot hole 113. The mold flipping device 12 has a support seat 121 for mounting the upper mold device 13. A pivot portion 122 extends from both sides of the support seat 121. The pivot portion 122 can extend into the pivot hole 113 and is pivotally mounted with the pivot hole 113.

[0003] During operation, the bottom mold device 14 moves toward the upper mold device 13, so that the bottom mold device 14 is tightly fitted to the upper mold device 13. At the same time, the bottom mold device 14 will generate a top pressure on the upper mold device 13. Since the bearing seat 121 is pivotally mounted on the pivot hole 113 through the pivot parts 122, the top pressure will cause certain stress to the pivot parts 122. Therefore, in order to avoid the pivot parts 122 from being able to withstand large stress, a higher strength specification must be used when selecting the pivot parts 122, so the manufacturing cost will be relatively increased.

[0004] Continuing from the above, even when using higher strength specifications, because the pivot 122 is a single-point support, the stress of its top pressure will be concentrated at a single point. Furthermore, under the rapid and repeated operation of the hot press molding machine, the problem of the pivot 122 breaking is still unavoidable, resulting in poor durability. Therefore, to maintain the normal operation of the hot press molding machine 1, the pivot 122 must be inspected or replaced periodically, increasing equipment maintenance costs. Moreover, since the pivot hole 113 needs to bear the force of the pivot 122, a bearing cannot be installed between the pivot hole 113 and the pivot 122, otherwise the bearing would easily be damaged by the stress. Therefore, during the rotation of the pivot 122, it can only rely on the lubrication on the pivot hole 113. Over time, due to the lack of a bearing, the pivot hole 113 is also prone to wear, gradually creating a gap between the pivot hole 113 and the pivot 122, causing errors in the operation process and a decrease in overall accuracy, which urgently needs improvement. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a hot press molding machine that can improve service life and durability, and reduce manufacturing and subsequent equipment maintenance costs.

[0006] Therefore, the hot pressing molding machine of the present invention includes a machine base, a mold flipping device pivotally mounted on the machine base, an upper mold device mounted on the mold flipping device, and a bottom mold device mounted on the machine base; wherein, the mold flipping device has a support base, and sliding groups are respectively disposed on both sides of the support base and disposed on the support frame, and an extension block is provided on both sides of the support base, and the upper edge of the extension block forms a top contact surface; in addition, each support frame is provided with a sliding hole, and the top edge of the sliding hole has an upper edge surface, and the extension block can extend through the sliding hole and be pivotally mounted with the sliding seat of the sliding group; at the same time, the top contact surface is disposed opposite to the upper edge surface, so that after the support base moves to a certain stroke, it will abut against the upper edge surface and be fixed by the upper edge surface.

[0007] As a further improvement of the present invention, the upper edge surface is a plane.

[0008] As a further improvement of the present invention, a bearing is provided between the sliding hole and the extension block.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] During operation, the bottom mold device moves upward to the support seat, and the support seat moves upward under the action of the bottom mold device until the top contact surface of the support seat contacts the upper edge surface and is restricted by the upper edge surface. Therefore, the top pressure of the bottom mold device on the support seat can be transmitted to the upper edge surface through the top contact surface and absorbed. Thus, it can effectively prevent the top pressure of the bottom mold device from concentrating at the pivot point between the extension block and the sliding seat, effectively preventing damage to the extension block or the pivot point of the sliding seat, improving service life and durability. At the same time, the required strength of the extension block can also be reduced, which can also reduce manufacturing costs and subsequent maintenance costs. Attached Figure Description

[0032] The above and other technical contents, features and effects of the present invention will become clear from the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0033] See Figure 2 , Figure 3 In a preferred embodiment of the hot press molding machine 3 of the present invention, the hot press molding machine 3 includes a machine base 31, a mold flipping device 32 pivotally mounted on the machine base 31, an upper mold device 33 disposed on the mold flipping device 32, and a bottom mold device 34 disposed on the machine base 31; wherein, the machine base 31 has a base 311 for the bottom mold device 34 to be disposed, and two support frames 312 for the mold flipping device 32 to be disposed, and each of the support frames 312 is provided with a sliding hole 313, and the top edge of the sliding hole 313 has an upper edge surface 314, and in this embodiment, the upper edge surface 314 is a planar representation.

[0034] Continuing from the above, the mold-flipping device 32 has a rotatable support base 321 that can be mounted on the upper mold device 33, and sliding groups 322 disposed on both sides of the support base 321 and mounted on the support frame 312. Each sliding group 322 has at least two tracks 3221 fixed on the support frame 312, and a sliding seat 3222 that can be displaced on the two tracks 3221 and pivotally mounted on the support base 321. In addition, an extension block 3211 protrudes outward from both sides of the support base 321, and a top restraining surface 3212 is formed on the upper edge of the extension block 3211. The top restraining surface 3212 can correspond to the shape of the upper edge surface 314. When the upper edge surface 314 is flat, the top restraining surface 3212 is also flat, so that the top restraining surface 3212 and the upper edge surface 314 can be flat against each other to obtain better support force.

[0035] Continuing from the above, the extendable block 3211 can extend through the sliding hole 313 and be pivotally connected to the sliding seat 3222. Simultaneously, the top contact surface 3212 is positioned opposite the upper edge surface 314, so that after the support seat 321 moves to a certain distance, it will abut against the upper edge surface 314 and be fixed by it. Furthermore, due to the design of the top contact surface 3212 of the extendable block 3211 and the upper edge surface 314, the force exerted on the support seat 321 during movement can be absorbed, and this force will not be transferred to the support seat 321. At the pivot point between the sliding seat 3222 and the extension block 3211, in this embodiment, a bearing 323 is appropriately provided between the sliding hole 313 and the extension block 3211. The bearing 323 is not affected by the moving force of the bearing seat 321, thus avoiding damage to the bearing 323. At the same time, the bearing 323 can also avoid the problem of gaps caused by friction between the extension block 3211 and the sliding seat 3222, as seen in existing hot press molding machines. Therefore, the bearing seat 321 can operate more precisely.

[0036] See Figure 2 , Figure 3During operation, after the bottom mold device 34 moves upward to the support seat 321, the support seat 321 will move upward under the action of the bottom mold device 34 until the top contact surface 3212 of the support seat 321 contacts the upper edge surface 314. The top contact surface 3212 will be restricted by the upper edge surface 314, and since the upper edge surface 314 is a plane, it can withstand the top pressure force of the top contact surface 3212 on the upper edge surface 314. Therefore, the top pressure force of the bottom mold device 34 on the support seat 321 can be transmitted through the top contact surface 3212 to the upper edge surface 314. Therefore, the top pressure of the bottom mold device 34 can be effectively avoided from concentrating at the pivot point between the extension block 3211 and the sliding seat 322. In addition to effectively preventing damage to the pivot point between the extension block 3211 and the sliding seat 322, the bearing 323 can be provided at the pivot point between the extension block 3211 and the sliding seat 322 to improve the smoothness of operation, and at the same time improve the service life and durability. Furthermore, the extension block 3211 no longer bears the top pressure of the bottom mold device 34, so the required strength of the extension block 3211 can also be reduced, which can also reduce manufacturing costs and subsequent maintenance costs.

[0037] In summary, the main feature of the hot press molding machine of the present invention is that the mold-flipping device has a support base and sliding blocks disposed on both sides of the support base and mounted on the support frame. An extension block is provided on each side of the support base, and a top-bracing surface is formed on the upper edge of the extension block. The extension block can extend through the sliding hole and pivotally engage with the sliding seat of the sliding block. This allows the support base to be supported by the top-bracing surface and the upper edge surface after it moves upward by a certain stroke under the support. This avoids the force being concentrated at the pivot point between the support base and the sliding seat, preventing damage to the pivot point and effectively improving service life and durability, as well as reducing subsequent maintenance costs. Therefore, the purpose of the present invention is indeed achieved.

[0038] However, the above description is only for illustrating preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present invention should still fall within the scope of the patent of the present invention.
