Description

Technical Field

[0001] This utility model relates to the field of molds, specifically a high-strength plastic mold. Background Technology

[0002] High-strength plastic molds refer to molds that can withstand high-intensity pressure and friction, and possess high hardness, high wear resistance, high toughness, and good thermal stability. They can ensure that the molds maintain precise shape and size during the plastic molding process, producing high-quality plastic products. High-performance plastic mold materials mainly include two categories: thermoplastic plastics and thermosetting plastics. Thermoplastic plastics include polyamide (PA) and polycarbonate (PC), while thermosetting plastics include phenolic resin and epoxy resin.

[0003] In existing high-strength plastic mold technology, the front mold is usually disassembled from the rear mold by a crane. There is a large friction between the guide post of the rear mold and the sleeve of the front mold. When the crane moves the front mold, if the direction of movement of the front mold cannot be kept horizontal with the guide post of the rear mold, the guide post of the rear mold will get stuck inside the sleeve of the front mold, making it impossible for the front mold to be disassembled from the rear mold smoothly. This may cause scratches or wear on the surface of the high-strength plastic mold, thereby reducing its performance. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength plastic mold to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A high-strength plastic mold includes a front mold and a rear mold. A fixing plate is fixedly installed at one end of the rear mold, and a base plate is fixedly installed at one end of the fixing plate. A disassembly assembly for assisting in the disassembly of the plastic mold is provided on one side of the front mold and the rear mold.

[0006] Preferably, the disassembly assembly includes a connecting T-shaped plate, one side of which is fixedly mounted on the lower end of the base plate near the upper end. A micro motor is fixedly mounted on the upper end of the connecting T-shaped plate, and a rotating shaft is rotatably connected to the upper end of the micro motor. A rotating cylinder is fixedly mounted on the end of the rotating shaft away from the micro motor, and a threaded rod is rotatably connected inside the rotating cylinder.

[0007] Preferably, a bearing sleeve is fixedly fitted at the end of the threaded rod away from the rotating cylinder, the inner ring of the bearing sleeve rotates inside its outer ring, and a second clamping plate is fixedly installed at one end of the bearing sleeve.

[0008] Preferably, the upper end of the second clamping plate contacts the lower end of the top plate of the front mold on one side, and a sliding groove is provided inside one end of the second clamping plate. Threaded bolts are rotatably fitted inside the second clamping plate on one side, and the two threaded bolts are rotatably fitted inside the top plate of the front mold on one side. The outer sides of the two threaded bolts are rotatably connected to the first clamping plate, and the lower end of the first clamping plate contacts the upper end of the top plate of the front mold on one side.

[0009] Preferably, a movable bolt is rotatably fitted at one end of the first clamping plate, and a movable guide rod is fixedly connected to the outer side of the movable bolt near the center, and a fixing component is provided on the outer side of the movable guide rod near the center.

[0010] Preferably, the fixing component includes a sliding piece, which is slidably connected inside the sliding groove of the second clamping plate. One end of the sliding piece is fixedly connected to a first curved clamping piece, and one end of the first curved clamping piece is fixedly connected to a first connecting block. A fixing bolt is rotatably sleeved inside the first connecting block.

[0011] Preferably, a second curved clamping piece is fixedly connected to one side of one end of the second clamping plate, a second connecting block is fixedly connected to one end of the second curved clamping piece, a fixing bolt is rotatably connected inside the second connecting block, and the inner sides of the second curved clamping piece and the first curved clamping piece are clamped and contacted with the outer side of the movable guide rod near the center.

[0012] The beneficial effects of this utility model are: 1. This utility model, through component disassembly, starts with a micro motor, and the rotating shaft drives the rotating cylinder to rotate. The inside of the rotating cylinder is engaged with the threaded rod through the thread, further driving the threaded rod to rotate and move up and down. The threaded rod rotates within the inner ring of the bearing sleeve, thereby driving the front mold to move from the rear mold. This facilitates manual disassembly and keeps the front mold sleeve and the rear mold guide post horizontal, preventing the rear mold guide post from getting stuck inside the front mold sleeve. This prevents scratches or wear on the surface of the high-strength plastic mold, thus reducing its performance.

[0013] 2. In this utility model, the first clamping plate and the second clamping plate are connected by threaded bolts to form an initial clamping of the front mold in the vertical direction. After the movable guide rod, the first curved clamping plate and the second curved clamping plate clamp the front mold, the relative position of the clamping plate and the front mold is further locked from the side and perpendicular to the clamping plate, forming a three-dimensional fixed structure of "vertical clamping + lateral locking". This prevents the first clamping plate and the second clamping plate from loosening or displacing in the front mold when the front mold and the rear mold are separated under force.

[0020] In a specific embodiment, when it is necessary to separate the front mold 1 and the rear mold 2 of the plastic mold, the micro motor 52 is fixed on the connecting T-plate 51, and the connecting T-plate 51 is rigidly connected to the base plate 4 and the rear mold 2 to ensure the overall structure is stable when the power is output, and to avoid shaking that affects the accuracy. After the micro motor 52 is started, the rotating shaft 53 drives the rotating cylinder 54 to rotate. The inside of the rotating cylinder 54 is engaged with the threaded rod 55 through the thread, which further drives the threaded rod 55 to rotate and move up and down. The threaded rod 55 rotates in the inner ring of the bearing sleeve 56, thereby driving the front mold 1 to move from the rear mold 2, which facilitates manual operation and disassembly.

[0021] Please refer to Figures 3 to 4 As shown, as a technical optimization of this utility model, the fixing component 6 includes a sliding piece 61, which is slidably connected to the sliding groove 512 of the second clamping plate 58. One end of the sliding piece 61 is fixedly connected to a first curved clamping piece 62, and one end of the first curved clamping piece 62 is fixedly connected to a first connecting block 63.

When it is necessary to separate the front mold 1 and the rear mold 2 of the plastic mold, the micro motor 52 is fixed on the connecting T-plate 51. The connecting T-plate 51 is rigidly connected to the base plate 4 and the rear mold 2 to ensure the overall structure is stable when the power is output and to avoid shaking that affects the accuracy. After the micro motor 52 is started, the rotating shaft 53 drives the rotating cylinder 54 to rotate. The inside of the rotating cylinder 54 is engaged with the threaded rod 55 through the thread, which further drives the threaded rod 55 to rotate and move up and down. The threaded rod 55 rotates in the inner ring of the bearing sleeve 56, thereby driving the front mold 1 to move from the rear mold 2, which facilitates manual operation and disassembly.
