[0034] Sixth Embodiment
[0035] like Figure 1 , 2 and Figures 3-4 As shown, table legs 101 are fixedly connected to the bottom of the injection molding table 1. The table legs 101 are four in number and are fixedly installed at opposite corners of the injection molding table 1. The table legs 101 provide support for the entire injection molding table 1.
[0036] In use, in the initial state, the support spring 107 at the top of the bottom plate 104 pushes the sliding plate 105 upwards and fits on the bottom of the injection platform 1, at this time the injection tube 106 extends on the top of the injection platform 1, the injection solution is connected into the injection connecting tube 102 through the pipeline, and a certain pressure is applied to the injection solution in the pipeline to make it have the power to enter the mold. Due to the gravity of the lower mold shell 2, when the lower mold shell 2 is placed, the gravity is greater than the contraction potential energy of the support spring 107, which makes the injection tube 106 move downwards, and the sliding plate 105 at the bottom of the injection tube 106 will drive the support spring 107 to contract inwards, at the same time, the inlet 108 outside the injection tube 106 will slide into the injection connecting tube 102, at this time the injection solution in the injection connecting tube 102 will smoothly enter the injection tube 106 through the inlet 108, then the injection solution is discharged from the injection tube 106 into the inlet 205 of the lower mold shell 2, and then flows along the main runner 202 in the lower mold shell 2, and then is evenly distributed to each lower mold 204 through the branch runners 203 arranged equidistantly on both sides of the main runner 202, so as to realize the injection filling of the medical surgical instrument support mold, and after the injection solution enters the inlet 205, it will push the check plate 303 in the upper mold shell 3 to rise, the check plate 303 slides in the sliding groove 302 and compresses the check spring 305, so that the injection solution can smoothly enter the branch runner 203 through the main runner 202, and the whole injection process is completed. At the same time, in the process of injecting the injection solution from the bottom to the mold, the air in the mold can be discharged upwards through the overflow port 301 on the top of the mold upper layer 306 at the bottom of the upper mold shell 3, and the operator can also judge whether the injection solution completely enters the mold according to whether the injection solution overflows into the overflow port 301. When the injection of the medical surgical instrument support is completed, the lower mold shell 2 is lifted upwards to separate from the insertion state with the injection tube 106, at this time the injection tube 106 is no longer subjected to the downward pressure of the lower mold shell 2, the support spring 107 at the bottom of the injection tube 106 will drive the sliding plate 105 to move upwards until the sliding plate 105 fits on the bottom of the injection platform 1 again, so that the inlet 108 moves to the inside of the injection platform 1, and the injection solution in the injection connecting tube 102 cannot enter the injection tube 106, so as to stop the injection. At the same time, the check spring 305 in the upper mold shell 3 will push the check plate 303 to move downwards, so that it fits in the main runner 202 again, so as to prevent the backflow of the injection solution through the main runner 202, and ensure the shape stability of the product molded in the mold. Subsequent demolding and other operations can be carried out to take out the finished product of the medical surgical instrument support.
[0037] The above embodiment is only one of the preferred embodiments of the present application, and should not be used to limit the protection scope of the present application, but any insignificant modification or polishing made in the main design idea and spirit of the present application, the technical problems solved are still consistent with the present application, and should be included in the protection scope of the present application.
