Description

Technical Field

[0001] The present invention relates to the technical field of plastic molds, and in particular to an adjustable clamp for plastic molds. Background Art

[0002] Molds are various molds and tools used in industrial production to produce the desired products through methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. In short, molds are tools used to make molded objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the object's appearance by changing the physical state of the molded material. They are known as the "mother of industry." In the field of plastic mold manufacturing, with the increasing demand for diversified and high-precision plastic products, mold processing accuracy has become a key factor. Plastic molds are usually composed of many complex components.

[0027] When in use, the cylinder 7 is started by the controller 36, and the cylinder 7 drives the fixed plate 8 to move, and the fixed plate 8 drives the second template 3 to move. After the second template 3 is molded with the first template 2, the plastic raw material is injected into the mold cavity formed inside the first template 2 and the second template 3. After the plastic raw material inside the mold cavity is cooled and formed, it can be discharged. The sides of the first template 2 and the second template 3 are clamped and positioned by the positioning fixture. The motor 27 is used to drive the first template 2 and the second template 3 to ensure the stability of the first template 2 and the second template 3 during installation. The motor 27 drives the threaded rod 10 to rotate, the threaded rod 10 drives the threaded sleeve 11 to move, the threaded sleeve 11 drives the connecting block 12 to move, the connecting block 12 drives the mounting plate 13 to move, the mounting plate 13 drives the connecting column 14 to move, and the connecting column 14 drives the limit plate 15 to move the inside of the positioning groove 18, so that the two sides of the first template 2 and the second template 3 can be clamped and fixed to ensure the stability of the connection between the first template 2 and the second template 3. Qualitatively, the temperature at the bottom of the first template 2 is detected by the temperature sensor 26. Within the preset value range, a signal is sent to the controller 36, and the pump body is started by the controller 36. The pump body draws the coolant inside the box body 20 through the delivery pipe 21, and delivers it to the inside of the heat dissipation circulation pipe 23 through the connecting pipe 22. The top of the heat sink 24 contacts the bottom of the first template 2, and can deliver the heat conducted by the first template 2 to the surface of the heat dissipation fins 25, and take away the heat through the coolant circulating inside the heat dissipation circulation pipe 23, thereby accelerating the cooling efficiency of the internal temperature of the first template 2. After the temperature sensor 26 detects that the surface temperature of the first template 2 is lower than the preset value, the motor 27 is started to rotate through the controller 36, and the limit between the first template 2 and the second template 3 is released. At the same time, the cylinder 7 is started, and the cylinder 7 drives the second template 3 to separate from the first template 2, thereby achieving the effect of automatic mold separation, which is convenient for the staff to take the internal products.

[0028] Example 2 Based on the first embodiment, Figure 2-3As shown, the other side of the threaded rod 10 passes through the inner cavity of the mounting groove 9 and extends to the outside of the mounting groove 9. The other side of the threaded rod 10 is fixedly connected to the motor 27. Both sides of the connecting block 12 are fixedly connected to the slider 28. Both sides of the inner cavity of the mounting groove 9 are provided with a slide groove, and the slider 28 and the slide groove are slidably connected.

[0029] like Figure 2-3 As shown in FIG5 , the four corners of the top of the first template 2 are fixedly connected with positioning columns 29 , and the four corners of the top of the second template 3 are provided with positioning holes for use with the positioning columns 29 .

[0030] Furthermore, one side of the motor 27 is fixedly connected to the processing table 1, and the connecting block 12 and the slider 28 are an integrated structure. At the same time, the slider 28 extends to the inner cavity of the slide groove away from the side of the connecting block 12, and the positioning column 29 is adapted to the positioning hole.

[0031] During use, the motor 27 drives the threaded rod 10 to rotate, and the threaded rod 10 drives the connecting block 12 on its surface to move. Under the limiting action of the slider 28 and the slide groove, the connecting block 12 realizes horizontal linear movement on the surface of the threaded rod 10, thereby achieving the purpose of facilitating rapid positioning of the mold.

[0032] Furthermore, the output end of the motor 27 rotates with the threaded rod 10, and the motor 27 can drive the threaded rod 10 to rotate, thereby achieving the purpose of horizontal movement. At the same time, the slider 28 extends from one end of the connecting block 12 to the inner cavity of the slide groove, which can limit the connecting block 12 and ensure the stability of the connecting block 12 during movement.

[0033] The motor 27 is fixedly mounted on one side of the mounting block 10. The output shaft of the motor 27 is coaxially fixedly connected to the end of the screw rod 10 through a coupling. When the motor is driven, the screw rod 10 is driven to rotate, thereby causing the threaded sleeve 11 on the screw rod to move axially, driving the connecting block 12, the support plate 13 and the connecting block 14 to move laterally, thereby realizing the limiting and clamping of the two sides of the mold by the limiting plate 15.

[0034] like Figure 1-10 As shown, a first heat dissipation groove 30 is provided on both sides of the surface of the processing table 1, and the first heat dissipation groove 30 extends to the rear side of the processing table 1. A second heat dissipation groove 31 is provided on the surface of the processing table 1. The inner cavity of the second heat dissipation groove 31 is fixedly connected to a mounting bracket 32, and one side of the mounting bracket 32 ​​is fixedly connected to a fan 33. A fixing bracket 34 is provided on both sides of the surface of the heat dissipation circulation pipe 23, and one side of the fixing bracket 34 is fixedly connected to the inner cavity of the processing table 1.

[0036] When in use, by starting the fan 33, the air flow generated by the fan 33 enters the interior of the processing table 1, and quickly dissipates the heat conducted on the surface of the heat dissipation fins 25. At the same time, the first heat dissipation groove 30 and the second heat dissipation groove 31 can achieve the purpose of air circulation, further improving the heat dissipation efficiency of the heat inside the mold. The heat dissipation circulation pipe 23 can be reinforced by the fixing bracket 34, ensuring the stability of the installation of the heat dissipation circulation pipe 23.

[0037] like Figure 1-6 As shown, a controller 36 is fixedly connected to the right side of the surface of the processing table 1. The controller 36 is electrically connected to the cylinder 7 and the pump body through wires. The detection end of the temperature sensor 26 is in contact with the bottom of the first template 2, and the output end of the temperature sensor 26 is electrically connected to the input end of the controller 36 in a unidirectional manner.

[0038] During use, the start and stop of the cylinder 7 and the pump body are controlled by the controller 36, and the temperature of the surface of the first template 2 is detected by the temperature sensor 26. After high temperature is detected, the pump body and the fan 33 are started respectively by the controller 36, which can achieve the dual cooling effect of air cooling and water cooling, thereby ensuring the molding efficiency of the product inside the mold.

[0039] Furthermore, the temperature sensor 26 is set into two groups, which are installed on both sides of the bottom of the first template 2 respectively, and can monitor the temperature of the first template 2 at the same time. After integrating the data, a more accurate judgment of the temperature can be made, which is used to intelligently monitor the molding state of the product and facilitate the picking of the product.

[0040] like Figure 1-4 As shown, the four corners of the bottom of the processing table 1 are fixedly connected with support columns 37, and the support columns 37 are symmetrically arranged.

[0041] When in use, the processing table 1 is supported by the support column 37, thereby ensuring the overall stability of the processing table 1 and improving the use effect of the adjustable clamp.

[0042] Working principle: The cylinder 7 is started by the controller 36, and the cylinder 7 drives the fixed plate 8 to move, and the fixed plate 8 drives the second template 3 to move. After the second template 3 is molded with the first template 2, the plastic raw material is injected into the mold cavity formed inside the first template 2 and the second template 3. After the plastic raw material inside the mold cavity is cooled and formed, it can be discharged. The side surfaces of the first template 2 and the second template 3 are clamped and positioned by the positioning fixture. The motor 27 is used to drive the first template 2 and the second template 3 to ensure the stability of the first template 2 and the second template 3 during installation. The motor 27 drives the threaded rod 10 to rotate, the threaded rod 10 drives the threaded sleeve 11 to move, the threaded sleeve 11 drives the connecting block 12 to move, the connecting block 12 drives the mounting plate 13 to move, the mounting plate 13 drives the connecting column 14 to move, and the connecting column 14 drives the limit plate 15 to move the inside of the positioning groove 18, so that the two sides of the first template 2 and the second template 3 can be clamped and fixed to ensure the connection between the first template 2 and the second template 3. Stability. The temperature at the bottom of the first template 2 is detected by the temperature sensor 26. Within the preset value range, a signal is sent to the controller 36, and the pump body is started by the controller 36. The pump body draws the coolant inside the box body 20 through the delivery pipe 21, and delivers it to the inside of the heat dissipation circulation pipe 23 through the connecting pipe 22. The top of the heat sink 24 contacts the bottom of the first template 2, and can deliver the heat conducted by the first template 2 to the surface of the heat dissipation fins 25, and take away the heat through the coolant circulating inside the heat dissipation circulation pipe 23, thereby accelerating the cooling efficiency of the internal temperature of the first template 2. After the temperature sensor 26 detects that the surface temperature of the first template 2 is lower than the preset value, the motor 27 is started to rotate through the controller 36, and the limit between the first template 2 and the second template 3 is released. At the same time, the cylinder 7 is started, and the cylinder 7 drives the second template 3 to separate from the first template 2, thereby achieving the effect of automatic mold separation, which is convenient for the staff to take the internal products.
