Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for preventing material from overflowing. Background Art

[0002] Injection mold is a tool for producing plastic products, and it is also a tool that gives plastic products a complete structure and precise size. In order to reduce the heavy workload of mold design and manufacturing, most injection molds use standard mold frames. However, traditional injection molds may cause working fluid overflow during operation.

[0003] Publication No. CN206383427U3 discloses an anti-overflow and heatable injection mold, which makes the mold more tightly closed by means of grooves and protrusions, and prevents overflow during mold closing by means of leakproof gaskets; and the injection liquid is heated by means of electric heating wires on the movable mold and electric heating plates on the fixed mold. The application of the anti-overflow and heatable injection mold described in the utility model can indirectly improve product quality, but the patent still has the following problems in actual use:

[0004] The grooves are matched with the protrusions to make the mold closer when closing, and the leak-proof gaskets are used to prevent overflow when closing the mold. At the same time, the leak-proof gaskets are only located on the left and right sides, and there are no leak-proof gaskets on the front and back sides, which makes it easy for materials to overflow from the front and back sides when closing the mold, thereby causing material waste. At the same time, after the injection molded product is cooled, it is inconvenient for the staff to take the injection molded product, which is easy to cause damage to the injection molded product when taking it out of the mold.

At the same time, after the baffle 11 contacts the top of the lower template 5, the baffle 11 is moved by the force of the first electric telescopic rod 3, and the movement of the baffle 11 causes the top rod 10 to move, so that the fit between the baffle 11 and the lower template 5 can be tighter. At the same time, the first card slot 6 and the first leak-proof pad 7 are opened around the upper template 4, and the second card slot 14 and the second leak-proof pad 13 are opened around the lower template 5, so that a protection effect can be provided in the four directions of front, back, left and right, thereby avoiding overflow of materials.

Figure 2-4 As shown, by starting the second electric telescopic rod 1703, the second electric telescopic rod 1703 can drive the movement of the slide plate 1702, so that the sliding groove 1704 can drive the movement of the sliding block 1705. At the same time, because the sliding groove 1704 is irregular, when the sliding groove 1704 moves left and right, it will drive the sliding block 1705 to rise or fall, so that the rise or fall of the sliding block 1705 can drive the rise or fall of the top plate 1706, so that the placement plate 18 can be raised or lowered. At the same time, sealing pads 19 are installed on both sides of the placement plate 18.

At the same time, after the baffle 11 contacts the top end of the lower template 5, the force of the first electric telescopic rod 3 descending causes the baffle 11 to move, and the movement of the baffle 11 causes the push rod 10 to move, so that the fit between the baffle 11 and the lower template 5 can be tighter.

[0035] Secondly, by setting up the jacking component 17 and starting the second electric telescopic rod 1703, the second electric telescopic rod 1703 can drive the movement of the slide plate 1702, so that the sliding groove 1704 can drive the movement of the sliding block 1705. At the same time, because the sliding groove 1704 is irregular, when the sliding groove 1704 moves left and right, it will drive the sliding block 1705 to rise or fall, so that the rise or fall of the sliding block 1705 can drive the rise or fall of the top plate 1706, so that the placement plate 18 can be raised or lowered. At the same time, sealing pads 19 are installed on both sides of the placement plate 18, and the sealing pads 19 fit tightly with the mold groove 15.
