Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fully automated embedded metal plastic molds, in particular to a fully automated embedded metal plastic mold. Background Art
[0002] Some injection molded parts require metal nuts, so during injection molding, the nuts need to be placed in the injection flow channel so that the nuts and the injection molded parts are tightly combined.
[0003] The injection molding part of existing plastic molds is often set to be conical, and the fluid plastic flows from the large end to the small end to reduce the introduction of air into the fluid plastic and cause injection failure; however, since the low flow rate gradually turns to a high flow rate, the speed of the fluid plastic injected into the cavity is difficult to control, resulting in uneven fluid in the cavity, affecting the quality of the injection molded parts.
[0004] An existing patent (publication number: CN 209999610 U) discloses a plastic mold for embedding nuts, which reduces the flow rate of the fluid plastic flowing into the cavity and improves the quality of the injection molded part by allowing the fluid plastic to flow from the small end of the flow channel to the large end of the flow channel through the basin.
[0005] However, the above technical solution still has certain defects. The existing embedded nut mold generally uses an insertion rod to insert the nut into the mold, and then injects plastic to form an integral body. The insertion rod will be inserted into the inner wall of the nut. The inner wall of the nut is provided with an internal thread. There will be a gap between the internal thread and the outer wall of the insertion rod. When injecting plastic, the plastic will generally overflow into the internal thread, thereby affecting the use of the internal nut. For this reason, a fully automated embedded metal plastic mold is proposed. Utility Model Content

[0029] The anti-overflow glue mechanism 100 includes a conical seat 106, a plurality of groups of slide grooves 109 are arranged in a circumferential array at the end of the conical seat 106, the inner walls of the plurality of groups of slide grooves 109 are slidably connected with sliders 110, the side walls of the plurality of groups of sliders 110 are fixedly connected with support rods 111, the outer walls of the plurality of groups of support rods 111 are fixedly connected with silicone sleeves 108, the inner wall of the insertion rod 105 is slidably connected with a pull rod 112, and the left end of the pull rod 112 extends to the outside of the conical seat 106, and the left end of the pull rod 112 is fixedly connected with an inverted conical block 108. 13.

[0030] First, put the nut on the conical seat 106 and the silicone sleeve 108, and drive the nut to be inserted into the lower mold groove 103 and the upper mold groove 104 through the insertion rod 105. When the outer wall of the lower mold seat 101 abuts against the push rod 116, continue to insert the insertion rod 105. At this time, the push rod 116 drives the inverted cone block 113 and the sealing plate 114 to stop moving through the pull rod 112. At this time, the inverted cone block 113 is inserted into the multiple groups of support rods 111.

[0035] During use, after the insertion rod 105 drives the nut to be inserted into the lower mold groove 103 and the upper mold groove 104, the multiple groups of support rods 111 will automatically move away from each other to drive the silicone sleeve 108 to open, so that the silicone sleeve 108 can fill the internal thread in the nut. At this time, the plastic can be prevented from flowing into the internal thread during injection molding, thereby preventing the use of the nut from being affected. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
