Sliding block resetting structure of injection mold

Abstract

The utility model discloses an injection mold slider resetting structure, which comprises a fixed frame, a fixed mold, a pressing plate, a movable mold and a reinforcing plate, the left side and the right side of the fixed frame are fixedly connected with sliding mechanisms, and the four corners of the bottom of the inner wall of the fixed frame are fixedly connected with supporting mechanisms. By arranging the through groove, the movable plate and the electric ejector rod, the movable plate can be movably limited by the through groove, and the movable plate can be driven to ascend in the fixed mold by starting the electric ejector rod, so that a user can conveniently take out an injection molding finished product, and the problem that the sliding plate needs to be repeatedly pressed by the user during use, so that the injection molding finished product cannot be conveniently taken out is solved. Meanwhile, due to the fact that the bottom of a sliding plate is in sliding connection with the top of a first sliding block and the top of a second sliding block, the distance between the sliding plate and the first sliding block and the distance between the sliding plate and the second sliding block are small, a user is difficult to collect finished products after injection molding is completed, and use is convenient. Therefore, the use is relatively inconvenient.

Description

Technical Field

[0001] The utility model relates to the technical field of mold slider reset structures, in particular to an injection mold slider reset structure. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the required 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. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. It is known as the "mother of industry."

[0003] For example, the authorization announcement number CN214353844U discloses a two-color injection mold slider reset structure, which relates to the technical field of mold slider reset structures. The utility model includes a base plate, and two first guide assemblies and a second guide assembly are symmetrically fixed on the upper side of the base plate. The first guide assembly includes two first guide bars, and a first sliding block is slidably fitted between the two first guide bars. The second guide assembly includes two second guide bars, and a second sliding block is slidably fitted between the two second guide bars. The utility model can guide the first sliding block and the second sliding block through the installation of the first guide assembly and the second guide assembly, so that the first sliding block and the second sliding block are more stable during the sliding process. The installation of the sliding plate can push the first sliding block and the second sliding block to slide to complete the injection molding, making the structure simpler. The installation of the first spring and the second spring can reset the first sliding block and the second sliding block respectively.

[0029] refer to Figure 4 A movable groove 11 is provided on the outer side of the vertical plate 91. The bottom of the inner wall of the movable groove 11 is movably connected to a limit plate 12. The limit plate 12 is arranged in a parallelepiped. The top of the limit plate 12 is movably connected to the top of the inner wall of the movable groove 11.

[0030] As a technical optimization solution of the present invention, by setting a movable groove 11 and a limit plate 12, the movable groove 11 can movably limit the limit plate 12. When the bottom of the pressing plate 3 is in contact with the top of the fixed frame 1, the pressing plate 3 can be limited by pushing the limit plate 12 to move it to the top of the pressing plate 3, which is convenient for injection molding.

[0031] refer to Figure 4 The bottom of the vertical plate 91 is fixedly connected to the mounting plate 13, the top of the mounting plate 13 is fixedly installed with an electric push rod 14, and the output end of the electric push rod 14 is fixedly connected to the push plate 15.

[0036] As a technical optimization solution of the present invention, by providing a support column 19 and a base plate 20 , the base plate 20 can fix and limit the electric push rod 8 , and the support column 19 is used to connect the base plate 20 and the mounting plate 13 .

[0037] The working principle and use process of the present invention are as follows: when in use, the heated and melted plastic raw material is first injected into the fixed mold 2, and then the pressing plate 3 is pressed down to drive the movable mold 4 to move downward. At this time, the pressing plate 3 compresses the supporting spring 102, and the slider 92 slides downward inside the slide groove 93. When the bottom of the pressing plate 3 is in contact with the top of the fixed frame 1, the output end of the electric push rod 14 is activated to drive the push plate 15 to move upward. When the top of the push plate 15 contacts the bottom of the limit plate 12 and continues to move upward, it can drive the limit plate 12 to move toward the top of the pressing plate 3, thereby limiting the pressing plate 3 upward. At the same time, the limit plate 12 moves and drives the interlocking plate 17 to move to squeeze the telescopic spring 18. After the injection molding is cooled, the electric push rod 14 is controlled to make the output end of the electric push rod 14 drive the push plate 15 to return to its original position. At this time, the telescopic spring 18 pushes the interlocking plate 17 and the limit plate 12 back to their original positions. When the limit plate 12 is away from the top of the pressure plate 3, the support spring 102 pushes the pressure plate 3 and the movable mold 4 to move upward and back to their original positions. At the same time, the pressure plate drives the slider 92 to slide upward inside the slide groove 93 and back to its original position. Finally, by starting the electric push rod 8, the output end of the electric push rod 8 pushes the movable plate 7 to rise inside the fixed mold 2, which is convenient for the user to take out the injection molded product.

[0038] To sum up: the injection mold slider reset structure, by setting a through groove 6, a movable plate 7 and an electric push rod 8, the through groove 6 can limit the movable plate 7, and by starting the electric push rod 8, the movable plate 7 can be driven to rise inside the fixed mold 2, so that the user can take out the injection molded product conveniently, which solves the problem that when in use, the user needs to press the sliding plate repeatedly and maintain pressure during the injection molding process, so it is more laborious to use. At the same time, since the bottom of the sliding plate is slidably connected to the top of the first slider and the second slider, the distance between the sliding plate and the first slider and the second slider is relatively close, and it is difficult for the user to collect the finished product after the injection molding is completed, so it is more inconvenient to use.
