Technical Field

[0001] The patent of this invention relates to the field of thermoforming technology, and mainly relates to a lifting device used on a thermoforming mold. Background Art

[0002] Thermoforming is a special plastic processing method that processes thermoplastic plastic sheets into various products. Corresponding molds are required during the processing, and a lifting device is required to remove them after they are made. However, the existing lifting devices have poor stability and it is difficult to separate the lifting plate from the lower surface of the molded workpiece, resulting in manual separation, which increases the workload of the staff. Therefore, it is necessary to design a lifting device for thermoforming molds to solve the above problems. Summary of the invention

[0003] The present invention mainly provides a lifting device for a thermoforming mold to solve the technical problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the following technical scheme is provided: a lifting device for a hot forming mold, comprising a lower mold, wherein both sides of the top of the lower mold are connected to a limiting mechanism, one side of the lower mold is provided with a mold groove, the bottom of the groove body of the mold groove is connected to the lifting mechanism, the lifting mechanism comprises a two-way screw rod rotatably connected to the bottom of the groove body of the mold groove, a rotating motor connected to one side of the two-way screw rod, a support block connected to both sides of the two-way screw rod and a support rod rotatably connected to the top of the support block, the top of the support rod is rotatably connected to a lifting plate, the lifting plate is slidably connected to the groove body of the mold groove, and the two sides of the top of the lifting plate are connected to a separation mechanism, the separation mechanism comprises a telescopic component connected to both sides of the top of the lifting plate, a first spring sleeved on the outer wall of the telescopic component and a mold bottom plate connected to one side of the telescopic component, and the mold bottom plate is slidably connected to the groove body of the mold groove.

[0005] In the present invention, the rotation of the bidirectional screw drives the two support blocks to move in opposite directions, thereby causing the support rod to rotate. The rotation of the support rod drives the lifting plate to rise and fall. The elastic force of the first spring facilitates the movement of the mold bottom plate, thereby separating the mold bottom plate from the workpiece, making it easier for the staff to take out the workpiece.

[0006] Furthermore, first bevels are provided on both sides of the top of the groove body of the mold groove;

[0007] A second bevel is provided on one side of the bottom of the mold bottom plate, and the second bevel matches the first bevel.

[0008] In the present invention, the second bevel cooperates with the first bevel to facilitate the mold bottom plate to squeeze the lower mold to move the mold bottom plate and achieve shrinkage.

[0009] Furthermore, a vertical plate is fixed on the top of the lifting plate, and multiple telescopic components are connected on both sides of the vertical plate. The telescopic components include a fixed cylinder connected to one side of the lifting plate and a sliding rod slidably connected to one side of the fixed cylinder, and one side of the sliding rod is connected to the mold bottom plate.

[0010] Furthermore, wedge-shaped stoppers are fixed on both sides of the top of the groove body of the mold groove, and rubber pads are fixed on the oblique sides of the wedge-shaped stoppers, and the rubber pads cooperate with the second oblique sides.

[0011] In the present invention, the wedge-shaped stopper limits the descending position of the mold bottom plate, and the rubber pad avoids the rigid contact between the mold bottom plate and the wedge-shaped stopper.

[0012] Furthermore, first T-shaped sliding grooves are provided on both sides of the bottom of the mold groove;

[0013] First T-shaped sliding blocks are fixed on both sides of the bottom of the support block, and the first T-shaped sliding blocks are slidably connected to the groove body of the first T-shaped sliding groove.

[0014] In the present invention, the cooperation between the first T-shaped sliding block and the first T-shaped sliding groove improves the stability of the support block and prevents the support block from rotating with the bidirectional screw rod.

[0015] Furthermore, second T-shaped sliding blocks are fixed on both sides of the bottom of the mold bottom plate;

[0016] Second T-shaped sliding grooves are arranged on both sides of the top of the lifting plate, and the groove body of the second T-shaped sliding groove is slidably connected with the second T-shaped sliding block.

[0017] In the present invention, the second T-shaped sliding block improves the stability of the mold bottom plate and avoids bending and damage of the sliding rod.

[0018] Furthermore, a groove is provided on one side of the bottom of the mold base plate, and the upper surface of the groove is parallel to the upper surface of the vertical plate.

[0019] In the present invention, the groove facilitates the contact between the mold bottom plates, thereby avoiding the occurrence of a gap between the two mold bottom plates, which may lead to workpiece processing failure.

[0020] Furthermore, hidden grooves are provided on both sides of the top of the mold groove, and the groove body of the hidden groove is connected to a limiting mechanism. The limiting mechanism includes a second spring connected to the groove body of the hidden groove and a limiting rod connected to one side of the second spring, and the limiting rod is slidably connected to the groove body of the hidden groove.

[0021] In the present invention, the elastic force of the second spring facilitates the limiting rod to press the workpiece, thereby limiting the position of the workpiece.

[0022] Furthermore, third oblique edges are provided on both sides of the limit rod, one side of the limit rod is rotatably connected to a roller, and a rubber pad is installed on the outer wall of the roller.

[0023] In the present invention, the third beveled edge facilitates the upper mold and the workpiece to squeeze the limit rod, thereby causing the limit rod to shrink. The roller facilitates reducing the friction between the workpiece and the limit rod, facilitating the lifting and lowering of the workpiece. The rubber pad facilitates increasing the lateral friction between the workpiece and the limit rod, preventing the workpiece from moving left and right.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention provides a lifting device for a hot forming mold, which drives the two-way screw rod to rotate by a rotating motor, thereby driving the two support blocks to move in opposite directions, and then rotating the support rod. The rotation of the support rod drives the lifting plate to rise, and the elastic force of the second spring facilitates the limit rod to squeeze the workpiece, thereby limiting the position of the workpiece. When the lifting plate rises to the first bevel, the elastic force of the first spring makes the second bevel of the mold bottom plate move in contact with the first bevel, thereby separating the mold bottom plate from the workpiece, making it convenient for the staff to take out the workpiece, avoiding the adhesion of the workpiece to the mold bottom plate, which causes the staff to manually separate the workpiece, thereby reducing the labor intensity of the staff, and improving the stability of the lifting plate by arranging multiple support rods, thereby avoiding the shaking of the lifting plate.

DETAILED DESCRIPTION

[0033] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0034] For example, please refer to Figure 1-5 , a lifting device for a hot forming mold, comprising a lower mold 10, wherein both sides of the top of the lower mold 10 are connected to a limiting mechanism 40, a mold groove is provided on one side of the lower mold 10, and the bottom of the groove body of the mold groove is connected to a lifting mechanism 20, wherein the lifting mechanism 20 comprises a bidirectional screw rod 22 rotatably connected to the bottom of the groove body of the mold groove, a rotating motor 21 connected to one side of the bidirectional screw rod 22, a support block 23 connected to both sides of the bidirectional screw rod 22 and a support rod 24 rotatably connected to the top of the support block 23, wherein the top of the support rod 24 is rotatably connected to a lifting plate 25, wherein the lifting plate 25 is slidably connected to the groove body of the mold groove, and a separation mechanism 30 is connected to both sides of the top of the lifting plate 25, wherein the separation mechanism 30 comprises a telescopic component 31 connected to both sides of the top of the lifting plate 25, a first spring 32 sleeved on the outer wall of the telescopic component 31 and a mold bottom plate 33 connected to one side of the telescopic component 31, wherein the mold bottom plate 33 is slidably connected to the groove body of the mold groove.

[0035] It should be noted that, in the embodiment, the bidirectional screw rod 22 is driven to rotate by the rotating motor 21, thereby driving the two support blocks 23 to move in opposite directions, and then causing the support rod 24 to rotate. The rotation of the support rod 24 drives the lifting plate 25 to rise and fall. When the lifting plate 25 rises to the top of the mold groove, the elastic force of the first spring 32 moves the mold bottom plate 33, thereby separating the mold bottom plate 33 from the workpiece, making it easier for the staff to take out the workpiece and avoiding the workpiece from sticking to the mold bottom plate 33. In addition, by providing a plurality of support rods 24, the stability of the lifting plate 25 is improved, thereby avoiding the shaking of the lifting plate 25.

[0036] For example, please refer to Figure 1 , the first bevel edges 11 are provided on both sides of the top of the groove body of the mold groove;

[0037] A second bevel 331 is disposed on one side of the bottom of the mold bottom plate 33 , and the second bevel 331 matches with the first bevel 11 .

[0038] It should be noted that, in the embodiment, the second bevel 331 cooperates with the first bevel 11 to facilitate the mold bottom plate 33 to squeeze the lower mold 10 to move the mold bottom plate 33 and achieve shrinkage.

[0039] For example, please refer to Figure 1-2 A vertical plate is fixed on the top of the lifting plate 25, and multiple telescopic components 31 are connected on both sides of the vertical plate. The telescopic components 31 include a fixed cylinder 311 connected to one side of the lifting plate 25 and a sliding rod 312 slidably connected to one side of the fixed cylinder 311, and one side of the sliding rod 312 is connected to the mold bottom plate 33.

[0040] For example, please refer to Figure 1 Wedge-shaped blocks 12 are fixed on both sides of the top of the mold groove, and rubber pads are fixed on the oblique sides of the wedge-shaped blocks 12, and the rubber pads cooperate with the second oblique sides 331.

[0041] It should be noted that, in the embodiment, the wedge-shaped stopper 12 limits the descending position of the mold bottom plate 33, and the rubber pad avoids the rigid contact between the mold bottom plate 33 and the wedge-shaped stopper 12, and plays a silencing role.

[0042] For example, please refer to Figure 3 , a first T-shaped slide groove 13 is provided on both sides of the bottom of the mold groove;

[0043] First T-shaped sliding blocks 231 are fixed on both sides of the bottom of the support block 23 , and the first T-shaped sliding blocks 231 are slidably connected to the groove body of the first T-shaped sliding groove 13 .

[0044] It should be noted that, in the embodiment, the cooperation between the first T-shaped sliding block 231 and the first T-shaped sliding groove 13 improves the stability of the support block 23 and prevents the support block 23 from rotating with the bidirectional screw rod 22 .

[0045] For example, please refer to Figure 3 , second T-shaped sliders 332 are fixed on both sides of the bottom of the mold bottom plate 33;

[0046] Second T-shaped sliding grooves 251 are provided on both sides of the top of the lifting plate 25 , and the groove body of the second T-shaped sliding groove 251 is slidably connected to the second T-shaped sliding block 332 .

[0047] It should be noted that, in the embodiment, the second T-shaped slide groove 251 limits the movement range of the mold bottom plate 33, and the second T-shaped slider 332 improves the stability of the mold bottom plate 33 to prevent the slide rod 312 from bending and being damaged.

[0048] For example, please refer to Figure 1 A groove is provided on one side of the bottom of the mold bottom plate 33, and the upper surface of the groove is parallel to the upper surface of the vertical plate.

[0049] It should be noted that, in the embodiment, the groove facilitates the contact between the mold bottom plates 33 to avoid a gap between the two mold bottom plates 33 that would cause workpiece processing failure.

[0050] For example, please refer to Figure 5 Hidden grooves are provided on both sides of the top of the mold groove, and the groove body of the hidden groove is connected to a limiting mechanism 40. The limiting mechanism 40 includes a second spring 41 connected to the groove body of the hidden groove and a limiting rod 42 connected to one side of the second spring 41. The limiting rod 42 is slidably connected to the groove body of the hidden groove.

[0051] It should be noted that, in the embodiment, the elastic force of the second spring 41 facilitates the limiting rod 42 to press the workpiece, thereby limiting the position of the workpiece.

[0052] For example, please refer to Figure 5 The limiting rod 42 has third bevel edges 421 on both sides thereof. One side of the limiting rod 42 is rotatably connected to a roller 422 , and a rubber pad is installed on the outer wall of the roller 422 .

[0053] It should be noted that, in the embodiment, the third bevel 421 facilitates the upper mold and the workpiece to squeeze the limit rod 42, thereby shrinking the limit rod 42, the roller 422 facilitates reducing the friction between the workpiece and the limit rod 42, and facilitates the lifting of the workpiece, and the rubber pad facilitates increasing the lateral friction between the workpiece and the limit rod 42 to prevent the workpiece from moving left and right.

[0054] The specific operation mode of the present invention is as follows:

[0055] The above-mentioned lifting device for a hot forming mold drives the bidirectional screw 22 to rotate by rotating the motor 21, thereby driving the two support blocks 23 to move in opposite directions, thereby rotating the support rod 24, and the rotation of the support rod 24 drives the lifting plate 25 and the workpiece to rise. During the rising process, the workpiece squeezes the limit rod 42, thereby causing the limit rod 42 to contract. The elastic force of the second spring 41 facilitates the limit rod 42 to squeeze the workpiece, thereby limiting the position of the workpiece. When the lifting plate 25 rises to the first bevel 11, the elastic force of the first spring 32 causes the second bevel 331 of the mold bottom plate 33 to move in contact with the first bevel 11, thereby separating the mold bottom plate 33 from the workpiece, making it convenient for the staff to take out the workpiece;

[0056] When the lifting plate 25 descends, the mold bottom plate 33 squeezes the lower mold 10 to cause the mold bottom plate 33 to shrink.

[0057] The above-described embodiments only express the implementation methods of the present application, but for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
