Description

Technical Field

[0001] The utility model relates to the technical field of plastic part processing equipment, and particularly relates to a feeding and injection molding device for electric vehicle plastic parts. Background Technique

[0002] The feeding and injection molding device for electric vehicle plastic parts with the publication number of CN216506402U includes an upper mold, a lower mold, a support block, a hydraulic sleeve and a telescopic rod. The circumferential side of the telescopic rod is slidably connected to the inner wall of the hydraulic sleeve, and the upper surface of the telescopic rod is fixedly connected to the lower surface of the lower mold. The setting of the connecting block and the baffle plate in cooperation with the connecting column can prevent pollutants from entering the inside of the storage tank during the operation of the equipment, avoiding the adverse impact of pollutant mixing on the quality of electric vehicle plastic parts. The setting of the hydraulic sleeve and the telescopic rod in cooperation with the support block can achieve the effect of quickly opening or closing the injection molding device. On the premise of ensuring the sealing effect, the problem of low-efficiency opening and closing of the injection molding device of traditional equipment is solved. Compared with traditional equipment, the path for transporting the molten raw material of this device is shorter, avoiding the problem of too fast cooling of the molten state, which is beneficial to improving the working efficiency of feeding and injection molding of the equipment.

[0003] Through the setting of the connecting block and the baffle plate in cooperation with the connecting column, this device can prevent pollutants from directly entering the inside of the storage tank during the operation of the equipment, avoiding the adverse impact of pollutant mixing on the quality of electric vehicle plastic parts. However, the baffle plate rotates with the connecting block, lacking the pressing of the baffle plate, resulting in a gap between the baffle plate and the storage tank, allowing pollutants to gradually penetrate through the gap to the injection hole and then fall into the storage tank, affecting the quality of plastic parts.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a feeding and injection molding device for electric vehicle plastic parts as shown in Figures 1-5 , including a feeding device 1 and an injection molding device 2. The feeding device 1 is arranged at the top of the injection molding device 2. The feeding device 1 is used for feeding, and the injection molding device 2 is used for injection molding. It further includes:

[0025] A covering component 5, and the covering component 5 is used to cover the injection hole of the feeding device 1;

[0026] A pressing mechanism 6, and the pressing mechanism 6 is used to press the covering component 5. The pressing mechanism 6 includes a pressing rod 61, and the pressing rod 61 is used to closely adhere to the top of the covering component 5. A pressing member for driving the movement of the pressing rod 61 is arranged on the outer wall of the pressing rod 61;

[0027] A limiting plate 7, and the limiting plate 7 is used to limit the movement of the covering component 5.

[0028] Specifically, a lifting device 3 for opening the mold of the injection molding device 2 is arranged at the bottom of the injection molding device 2, and a fixed rod 4 for positioning the injection molding device 2 is arranged on one side of the injection molding device 2.

[0029] Furthermore, the working principles of the feeding device 1, the injection molding device 2, the lifting device 3 and the fixed rod 4 are the same as those of the feeding device, the injection molding device and the lifting device in the feeding and injection molding device for electric vehicle plastic parts with the publication number CN216506402U.

[0030] Specifically, the bottom end of the limit plate 7 is fixedly connected to the top end of the feeding device 1. The covering assembly 5 includes a covering plate 51. A sealing ring 52 for sealing is fixedly connected to the bottom end of the covering plate 51. One end of the covering plate 51 is provided with a rotating member for the covering plate 51 to be hinged. The rotating member includes a hinge column 53. The bottom end of the hinge column 53 is fixedly connected to the top end of the feeding device 1. A rotating hole is formed in the top end of the covering plate 51, and the hinge column 53 is inserted into the rotating hole.

[0031] Furthermore, the bottom end of the limit plate 7 is fixedly connected to the top end of the feeding device 1 by welding. The limit plate 7 is used to limit the movement of the rotating covering plate 51. When the covering plate 51 contacts the limit plate 7, the center point of the covering plate 51 and the center point of the injection hole are on the same vertical line. The size of the covering plate 51 is 1.3 times that of the injection hole. The top end of the sealing ring 52 is fixedly connected to the bottom end of the covering plate 51 by adhesion. The sealing ring 52 is circular, and the sealing ring 52 is made of rubber material. The bottom end of the hinge column 53 is fixedly connected to the top end of the feeding device 1. The diameter of the hinge column 53 matches the diameter of the rotating hole. A disc is welded to the top end of the hinge column 53 to prevent the covering plate 51 from slipping out of the hinge column 53, so that the covering plate 51 rotates around the hinge column 53.

[0032] Specifically, the pressing member includes a pushing spring 64. The pushing spring 64 is sleeved on the outer wall of the pressing rod 61. A baffle 63 for driving the pressing rod 61 to move is arranged at the bottom end of the pushing spring 64. The baffle 63 is fixedly sleeved on the outer wall of the pressing rod 61. An installation frame 65 for installing the pushing spring 64 is arranged on the outer wall of the pushing spring 64. A cavity is formed inside one end of the installation frame 65. The pushing spring 64 and the baffle 63 are both arranged in the cavity. A through hole for inserting the pressing rod 61 is formed in the inner wall of the cavity. The installation frame 65 is L-shaped, and the bottom end of the installation frame 65 is fixedly connected to the top end of the feeding device 1. A lifting plate 62 for pulling the pressing rod 61 is fixedly connected to the top end of the pressing rod 61.

[0033] Further, the bottom end of the pressing rod 61 is hemispherical. One end of the mounting bracket 65 is used to mount the pressing rod 61, and the other end is fixedly welded to the feeding device 1. The insertion hole is a round hole, and the diameter of the pressing rod 61 is 0.98 times the diameter of the insertion hole. The bottom end of the lifting plate 62 is welded and fixed to the top end of the pressing rod 61. The lifting plate 62 is a horizontal plate. The diameter of the pushing spring 64 is 1.2 times the diameter of the insertion hole. The baffle 63 is a rectangular plate. Both the baffle 63 and the pushing spring 64 are arranged in the cavity. The pushing spring 64 is always in a compressed state in the cavity. When the cover plate 51 rotates away from the pressing rod 61, under the push of the pushing spring 64, the baffle 63 drives the pressing rod 61 to move towards the feeding device 1, so that the bottom end of the baffle 63 fits against the bottom end of the inner wall of the cavity. When the cover plate 51 rotates towards the pressing rod 61, the cover plate 51 will squeeze the bottom of the pressing rod 61, causing the pressing rod 61 to move away from the feeding device 1. At this time, the pressing rod 61 will further squeeze the pushing spring 64 by driving the baffle 63, and the restoring force of the pushing spring 64 will push the baffle 63 to have a tendency to move towards the cover plate 51, so that the bottom end of the pressing rod 61 presses on the top end of the cover plate 51. Thus, the sealing ring 52 at the bottom end of the cover plate 51 deforms under the action of the cover plate 51 and the feeding device 1, filling the gap between the cover plate 51 and the feeding device 1 and ensuring the sealing effect of the injection hole.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
