DETAILED DESCRIPTION

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] First embodiment

[0023] See also Figure 1 to Figure 3 ,in Figure 1 is a schematic diagram of the overall structure of the first embodiment, Figure 2 is a front view of the overall structure of the first embodiment, Figure 3 It is a schematic structural diagram of part of the first embodiment.

[0024] The utility model provides a limiting device for injection mold processing: comprising an operating table 101, a support plate 102 and a limiting assembly, wherein the limiting assembly comprises a U-shaped frame 103, a bidirectional threaded rod 104, two sleeves 105, two clamping plates 106, a driving member and two extrusion sponge pads 111, wherein the driving member comprises a cylinder 107, a rack 108, a gear 109 and a slide rail 110. The above-mentioned solution solves the problem that the existing method of fixing the mold by manually twisting the adjusting rod to drive the clamping plate, the fixing process requires more manpower and time, and the operation is troublesome.

[0025] According to this specific embodiment, the support plate 102 is fixedly connected to the operating table 101 and is located inside the operating table 101. The limiting assembly is arranged on the support plate 102. The mold can be fixed on the operating table 101 by the limiting assembly, and then personnel can process the mold.

[0026] Wherein, the U-shaped frame 103 is fixedly connected to the support plate 102 and is located above the support plate 102. Both ends of the bidirectional threaded rod 104 are rotatably connected to the U-shaped frame 103. The two sleeves 105 are respectively sleeved on the outside of the bidirectional threaded rod 104 and are threadedly matched with the bidirectional threaded rod 104. The operating table 101 has a through groove 112. The two sleeves 105 are also slidably connected to the operating table 101 and are located in the through groove 112. The two clamping plates 106 are respectively fixedly connected to the corresponding sleeves 105 and are respectively located above the sleeves 105. The driving member is connected to the bidirectional threaded rod 104. When processing the mold, the mold is first placed above the operating table 101, and the mold is located between the two clamping plates 106. Then, the driving member on the support plate 102 is started. The driving member controls the bidirectional threaded rod 104 to rotate in the U-shaped frame 103. Since the two sleeves 105 are threadedly matched with the bidirectional threaded rod 104, the rotation of the bidirectional threaded rod 104 will drive the two sleeves 105 to move relative to each other in the through groove 112, and the two clamping plates 106 will also move until the two clamping plates 106 clamp and fix the mold, and then the fixed mold is processed; after the mold processing is completed, the bidirectional threaded rod 104 is driven to reverse in the U-shaped frame 103 by starting the driving member, and the two sleeves 105 will move away from each other, so that the two clamping plates 106 gradually move away from the processed mold, and then the mold is taken away, and the above process is repeated to process the mold. Through the above method, it is possible to easily fix the mold, save time and effort, reduce the processing time of the mold, and simplify the operation.

[0027] Secondly, the two extrusion sponge pads 111 are fixedly connected to the corresponding clamping plates 106 and are respectively located on the outer side walls of the clamping plates 106. By arranging the extrusion sponge pads 111 on the outer side of the clamping plates 106, the extrusion sponge pads 111 can increase the friction between the clamping plates 106 and the outer wall of the mold, so that the mold can be fixed more stably above the operating table 101.

[0028] At the same time, the slide rail 110 is fixedly connected to the support plate 102 and is located above the support plate 102. The rack 108 is movably connected to the slide rail 110 and is located inside the slide rail 110. The cylinder 107 is arranged above the support plate 102. The output end of the cylinder 107 is fixedly connected to the rack 108. The gear 109 is connected to the bidirectional threaded rod 104 and meshes with the rack 108. The cylinder 107 is fixed above the support plate 102. By starting the cylinder 107, the output end of the cylinder 107 pushes the rack 108 to move in the slide rail 110. Since the rack 108 is meshed with the gear 109, the movement of the gear 109 will drive the gear 109 to rotate, thereby causing the bidirectional threaded rod 104 to rotate in the U-shaped frame 103.

[0029] When processing the mold, first place the mold on the operating table 101, and the mold is located between the two clamping plates 106, then start the cylinder 107 on the support plate 102, and the output end of the cylinder 107 pushes the rack 108 to move in the slide rail 110. Since the rack 108 is meshed with the gear 109, the movement of the gear 109 will drive the gear 109 to rotate. At this time, the bidirectional threaded rod 104 rotates in the U-shaped frame 103. Since the two sleeves 105 are threadedly matched with the bidirectional threaded rod 104, the rotation of the bidirectional threaded rod 104 will drive the two sleeves 105 to rotate in the through-frame 103. The two clamping plates 106 move relative to each other in the through groove 112 until the two clamping plates 106 clamp and fix the mold, and then the fixed mold is processed; after the mold processing is completed, the rack 108 is reset by starting the cylinder 107, and the two-way threaded rod 104 is reversed in the U-shaped frame 103, and the two sleeves 105 move away from each other, so that the two clamping plates 106 gradually move away from the completed mold, and then the mold is taken away, and the above process is repeated to process the mold. Through the above method, it is possible to easily fix the mold, save time and effort, reduce the processing time of the mold, and simplify the operation.
