Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a special mold for verifying polycarbonate silver wires. Background Art

[0002] Hydrolyzed silver filaments refer to silver filaments formed by the hydrolysis of polycarbonate in the barrel. The reason for their formation is that the pellets are not fully dried before molding, or the fully dried pellets stay in the hopper for too long, and there is no effective insulation measure in the hopper, causing them to absorb moisture again, and the water content exceeds the specified requirements. The pellets with high water content are vaporized under the high temperature in the barrel, causing the resin to degrade during the melting process, and producing carbon dioxide and other gases that accumulate inside the molten resin. When punching the die, they are rushed into the mold cavity with the material flow to form hydrolyzed silver filaments, which significantly reduce the strength of the product and make the texture brittle.

[0003] This type of hydrolyzed silver thread is often encountered and relatively easy to identify. It is usually evenly distributed along the injection flow direction, and in severe cases, it covers the entire surface of the product.

[0004] The special mold for verifying polycarbonate silver threads is a special mold for detecting whether polycarbonate products have silver threads. When in use, polycarbonate is injected into the mold, and the silver threads of the injection molded parts are checked after cooling and molding. However, when the special mold for verifying polycarbonate silver threads in the prior art is in use, the plug is not tightly connected to the heating component, which easily leads to the loosening of the plug during use, thereby causing the heating component to be unable to heat the polycarbonate in the mold, reducing work efficiency.

[0005] Therefore, it is urgent to design a special mold for verifying polycarbonate silver wire to solve the above technical problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] In the description of this embodiment, unless otherwise specified, the term "plurality" refers to a quantity of two or more than two.

[0035] This embodiment provides a special mold for verifying polycarbonate silver wire, which can improve the stability and reliability of the connection between the plug and the heating component, reduce or avoid the loosening of the plug, and improve work efficiency.

[0036] like Figure 1-Figure 3 As shown, the special mold for verifying polycarbonate silver wire mainly includes a male mold 100, a female mold 200, a heating component 300 and a fastening sleeve 400. The male mold 100 and the female mold 200 are connected and jointly enclose an injection cavity for accommodating the product. A heating component 300 is provided on one of the male mold 100 or the female mold 200. The heating component 300 is configured to heat the product in the injection cavity; the end of the heating component 300 away from the injection cavity is used to connect with the plug 10. The fastening sleeve 400 is sleeved on the plug 10, and the fastening sleeve 400 is threadedly connected to the plug 10, and one side of the fastening sleeve 400 abuts against one side of the heating component 300.

[0037] The product in this embodiment can be set to polycarbonate, and of course it can also be other types of products. The heating component 300 is thermally connected to the injection cavity, so that the heating component 300 is conducive to heating and melting the product in the injection cavity. In actual use, the operator can plug the plug 10 into the heating component 300, and then sleeve and thread the fastening sleeve 400 on the plug 10, and finally screw it into place so that one side of the fastening sleeve 400 abuts against one side of the heating component 300. The setting of the fastening sleeve 400 can achieve a limiting effect on the plug 10, making the connection between the plug 10 and the heating component 300 more stable, reducing or avoiding the phenomenon of the plug 10 loosening or even falling off, and improving the working efficiency of the special mold for verifying polycarbonate silver wire.

The provision of the clamping assembly 500 can improve the stability and reliability of the connection between the male mold 100 and the female mold 200, avoid the phenomenon of relative dislocation, sliding and other displacement of the male mold 100 and the female mold 200 during the operation, and improve the reliability of the special mold for verifying polycarbonate silver wires.

[0045] Specifically, the snap-on assembly 500 in this embodiment includes a connecting plate 510, an elastic member 530 and a protrusion 540. A second groove 520 is provided on the connecting plate 510. The elastic member 530 is provided in the second groove 520. One end of the elastic member 530 is connected to the bottom wall of the second groove 520, and the other end is connected to the protrusion 540. The protrusion 540 is located on one side of the connecting plate 510, and the protrusion 540 is snap-connected to the first groove 120.

[0046] By setting the connecting plate 510, the elastic member 530 and the protrusion 540, the protrusion 540 can be connected with the first groove 120 by the action of the elastic member 530. Optionally, the clamping assembly 500 in this embodiment is provided with at least one, for example, it can be provided with one, two, three, four or the like, and each clamping assembly 500 is symmetrically provided with two elastic members 530 and two protrusions 540, under the action of the two elastic members 530, the two protrusions 540 can move away from each other, so that one of the protrusions 540 is clamped in the first groove 120 in the male mold 100, and the other protrusion 540 is clamped in the first groove 120 of the female mold 200, thereby realizing the connection function of the clamping assembly 500 on the male mold 100 and the female mold 200.

[0047] Furthermore, the clamping assembly 500 in this embodiment further includes a slider 550 and a fixing rod 560. The slider 550 is disposed in the second groove 520, the slider 550 is slidably connected to the side wall of the second groove 520, the bottom of the slider 550 is connected to one end of the elastic member 530 away from the bottom wall of the second groove 520, and the side end of the slider 550 is connected to the protrusion 540. One end of the fixing rod 560 is connected to the top wall of the second groove 520, and the other end is connected to the bottom wall of the second groove 520; the slider 550 and the elastic member 530 are both sleeved on the fixing rod 560.

[0048] The provision of the slider 550 can improve the convenience of compressing the elastic member 530, and the provision of the fixing rod 560 can play a certain guiding role in the movement of the slider 550 and the elastic member 530, avoiding the phenomenon of movement dislocation or offset, and improving the reliability and stability of the slider 550 compressing the elastic member 530. The two ends of the fixing rod 560 in this embodiment are respectively welded to the top wall and the bottom wall of the second groove 520, and the two ends of the elastic member 530 are respectively welded to the slider 550 and the bottom wall of the second groove 520. In addition, one side end of the slider 550 is welded to the protrusion 540, which can improve the stability and reliability of the clamping assembly 500 and extend its service life.

[0049] Furthermore, the clamping assembly 500 further includes a push plate 570, which is connected to one side end of the slider 550 away from the protrusion 540. Specifically, the push plate 570 can be welded to one side end of the slider 550 away from the protrusion 540. The provision of the push plate 570 can improve the convenience of the operator driving the slider 550 to compress the elastic member 530, thereby improving work efficiency and saving costs.

[0050] When the clamping assembly 500 is clamped in the first groove 120, along the direction of the push plate 570 pointing to the protrusion 540, the projection area of ​​the push plate 570 is not less than the projection area of ​​the second groove 520. In other words, the push plate 570 covers the second groove 520, thereby preventing foreign matter such as dust from the outside from entering the second groove 520 to contaminate the elastic member 530 and the fixing rod 560, thereby extending the service life of the clamping assembly 500 and saving costs.
