Abstract
Description
Technical Field
[0001] The utility model relates to the field of injection molds, in particular to a novel mold fixer for an injection molding machine. Background Art
[0002] Injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise size. Injection molding refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and obtaining a molded product after cooling and solidification. The injection mold consists of a movable mold and a fixed mold. The movable mold is installed on the movable mold plate of the injection molding machine, and the fixed mold is installed on the fixed mold plate of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to remove the plastic product.
[0003] During the injection molding of workpieces, the installation and fixation of the injection mold is an important step in the processing. The traditional injection mold fixation is relatively direct, and the upper and lower mold screws are used to directly fix the mold on the injection molding equipment. When different injection molds need to be replaced, the screws on the upper and lower molds need to be disassembled and reassembled, and it takes a long time to align the screw holes when re-replacing the mold. This method of replacing the left mold is not only troublesome to operate, but also greatly reduces work efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 - Figure 4, an embodiment provided by the utility model: a novel injection molding machine mold holder, including a left mold 16 and a working plate 1, a connecting frame 17 is fixedly connected to one side of the outer wall of the left mold 16, a second card slot 18 is opened inside the connecting frame 17, a first side plate 2 is fixedly connected to the upper surface of the working plate 1, a telescopic rod 3 is fixedly connected to one side of the outer wall of the first side plate 2, a clamping plate 4 is fixedly connected to the output end of the telescopic rod 3, a first card slot 5 is opened inside the clamping plate 4, a support plate 6 is fixedly connected to the upper surface of the clamping plate 4, a pull rod 10 is slidably connected inside the support plate 6, a third card slot 32 is opened inside the pull rod 10, a first spring 11 is sleeved on the outer wall of the pull rod 10, and a first spring 11 is provided on the lower surface of the pull rod 10 A clamping block 9 is fixedly connected to the surface, one end of a second telescopic spring 34 is fixedly connected to one side of the outer wall of the clamping block 9, and the other end of the second telescopic spring 34 is fixedly connected to a rotating plate 33. A T-shaped plate 7 is fixedly connected to the upper surface of the support plate 6, and an anti-slip clamping rod 12 is slidably connected inside the T-shaped plate 7. The outer wall of the anti-slip clamping rod 12 is sleeved with a second spring 13, and the outer wall of the anti-slip clamping rod 12 is fixedly connected to a limiting ring 14. A pulling assembly is provided on the upper surface of the T-shaped plate 7. The pulling assembly can enable the two pull rods 10 to move upward synchronously along a straight line. The pulling assembly includes a connecting plate 8. The lower surface of the connecting plate 8 is fixedly connected to the upper surface of the pull rod 10, and the upper surface of the connecting plate 8 is fixedly connected to a handle 15.
[0026] Specifically, in order to stabilize the left mold 16 more stably, a connecting frame 17 is fixed to the outside of the left mold 16, and the lower end of the connecting frame 17 is set to a tip that can just be engaged with the first card slot 5 to form a first card mechanism. Therefore, when in use, the lower end of the connecting frame 17 is first inserted into the first card slot 5, and then the upper end of the connecting frame 17 is directly pressed into the card plate 4. During the pressing process, the anti-dropping card rod 12 needs to be pulled outward. When the upper end of the connecting frame 17 is pressed into the card plate 4, it will press the oblique section of the card block 9 under the pull rod 10, so that the card block 9 moves upward, and then under the action of the first spring 11, the card block 9 is automatically lowered and connected to the connecting frame. The second card slot 18 at the upper end of the connecting frame 17 is engaged, and then the anti-dropping card rod 12 is released. Under the action of the second spring 13, the anti-dropping card rod 12 is automatically inserted into the pull rod 10, thereby realizing the fixation of the card block 9. A third card slot 32 is opened in the pull rod 10. When encountering molds of different sizes, different third card slots 32 will be engaged by the anti-dropping card rod 12 to complete the card connection and fixation of injection molds of different sizes. The first card connection mechanism composed of the connecting frame 17 and the first card slot 5, and the second card connection mechanism composed of the card block and the second card slot 18, the setting of the two card connection structures realizes the further fixation of the injection mold.
[0027] Reference Figure 4 - Figure 6A second side plate 19 is fixedly connected to the upper surface of the working plate 1, a sliding rod 20 is fixedly connected to one side of the outer wall of the second side plate 19, a second connecting block 24 is fixedly connected to one side of the outer wall of the second side plate 19, a cylinder 22 is fixedly connected to one side of the outer wall of the second side plate 19, a right mold 21 is fixedly connected to the output end of the cylinder 22, an injection hole 31 is opened inside the right mold 21, a connecting shaft 25 is fixedly connected to one side of the outer wall of the right mold 21, a first connecting block 23 is fixedly connected to the connecting shaft 25, one end of a first telescopic spring 26 is fixedly connected to one side of the outer wall of the first connecting block 23, the other end of the first telescopic spring 26 is fixedly connected to one side of the outer wall of the right mold 21, a pad 27 is fixedly connected to one side of the outer wall of the pad 27, a round rod 28 is fixedly connected to one side of the outer wall of the round rod 28, a stripping module 30 is fixedly connected to one side of the outer wall of the round rod 28, and a third spring 29 is sleeved on the outer wall of the round rod 28.
[0028] Specifically, when the demolding work is carried out, the cylinder 22 drives the two molds to approach the demolding module 30. At this time, the first connecting block 23 will move forward until the first connecting block 23 moves to the head of the second connecting block 24. The elastic action of the first telescopic spring 26 realizes the opening of the first connecting block 23, and then the two molds are disengaged. The telescopic action of the telescopic rod 3 drives the injection model adsorbed on the left mold 16 to move toward the demolding mechanism, and then the demolding structure composed of the third spring 29 and the demolding module 30 is used to realize automatic demolding after the injection molding is completed, thereby reducing the workload of workers in manual demolding.
[0029] Working principle: During use, first align the lower end of the new left mold 16 with the first card slot 5 in the card plate 4, and then press the upper end of the left mold 16 directly into the card plate 4. During the direct pressing process, it is necessary to pull the anti-dropping card rod 12 outward, and when the upper end of the left mold 16 is pressed into the card plate 4, it will press the rotating plate 33 connected to the lower end of the card block 9, so that the second telescopic spring 34 on the rotating plate 33 is compressed, thereby achieving the fixation of notches of different sizes. When the second telescopic spring 34 is compressed to close to the card block 9, the clamping block 9 will shrink, and then under the action of the first spring 11, the clamping block 9 will automatically drop and clamp with the second clamping groove 18 at the upper end of the left mold 16, and then release the anti-slip clamping rod 12, and under the action of the second spring 13, the anti-slip clamping rod 12 will automatically fit into the pull rod 10 to fix the clamping block 9, and under the clamping action of the left mold 16 and the first clamping groove 5 and the clamping block 9 and the second clamping groove 18 at both ends, the left mold 16 is fixed in the clamping plate 4, thereby realizing the fixed installation of the injection molding machine mold.
[0030] After the injection molding machine mold is fixedly installed, the telescopic rod 3 is started to drive the left mold 16 on the clamping plate 4 to move closer to the right mold 21 until the two molds are in contact. At the same time, the first connecting block 23 on the right mold 21 will also move backward, and the second spring 13 compressed on the first connecting block 23 will also recover, so that the first connecting block 23 is tightened inward, thereby being clamped on the outer side of the clamping plate 4, completing the preparation before injection molding.
[0031] When the injection molding is completed, the cylinder 22 is started to drive the two molds to move closer to the stripping module 30. At this time, the first connecting block 23 will contact the second connecting block 24 during the forward movement until the first connecting block 23 moves to the head of the second connecting block 24. Under the elastic action of the first telescopic spring 26, the first connecting block 23 will open to make the two molds out of contact. Then the telescopic rod 3 is started to drive the left mold 16 to move toward the stripping module 30. At this time, the third spring 29 connected to the outer sleeve of the round rod 28 will shrink until the stripping module 30 ejects the model in the left mold 16, thereby realizing automatic demolding after the injection molding is completed.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
