Description

Horn sprue with cold material for injection mold

Technical Field

The utility model relates to an injection mold takes ox horn runner of cold burden belongs to the injection mold field.

Background

The injection mold is adopted to produce plastic products, such as automobile decoration parts and the like, the requirements on the surfaces of the products are higher, particularly, the cold material treatment and the gate design of the products are realized, the gate of the injection mold generally adopts a horn gate, a cold material runner is not arranged on the horn gate, when the mold is injected, the temperature of part of plastic raw materials at the head part of the gate is lower than the requirement of injection temperature and is in a semi-solidification state, and the semi-solidified plastic raw materials are directly injected into the mold cavity of the mold by the traditional technology to influence the molding quality of the products.

Disclosure of Invention

The utility model aims at overcoming prior art's shortcoming, provide one kind and adopt U type runner and cold burden runner integrated design, with half solidification plastic raw materials pour into the cold burden runner into, guarantee product quality's injection mold takes the ox horn runner of cold burden.

The utility model discloses injection mold takes ox horn runner of cold charge's technical scheme is: the mold comprises a mold core, wherein a product mold cavity is arranged on the mold core, and an injection molded product is arranged in the product mold cavity.

The utility model discloses a ox horn runner of injection mold area cold charge, the key feature is that set up two huff runner inserts in the core, respectively set up half slit ox horn runner on two huff runner inserts lateral wall in opposite directions, and set up U type runner on one of them huff runner insert, set up sprue and cold charge runner on another huff runner insert, sprue, U type runner, ox horn runner, cold charge runner and die cavity are linked together, during the injection, the nozzle of mould is towards the sprue injection, the plastics raw materials of injection flow to the U type runner through the sprue, flow to ox horn runner again, but because ox horn runner is the runner of hiding, the runner is down, so when the plastics raw materials flow here, can directly flow through ox horn runner to the cold charge runner earlier, the flow of material flows the ox horn runner again, inject into product die cavity 2 at last, and the plastics raw materials of injecting first, namely, the semi-solidified plastic raw material at the head part of the sprue is remained in the cold material runner and cannot be injected into the product mold cavity 2, so that the product quality is ensured.

The utility model discloses an injection mold takes ox horn runner of cold charge, two blocks of huff runners on the side of inserting set up the lug, set up the transition die cavity on the lug, ox horn runner intercommunication transition die cavity, the transition die cavity cooperatees with the product die cavity, has had the transition die cavity, make ox horn runner and die cavity be connected closely not the hourglass and glue. And after the mold is opened, the ejector pins are driven by power to eject the Chinese remainders of the main runner, the cold material runner and the U-shaped runner out of the mold. The two half gate inserts are provided with fixing holes, the fixing holes are provided with screws, and the screws are fixedly connected with the mold core, so that the installation is convenient and firm.

Detailed Description

The utility model relates to an injection mold takes ox horn runner of cold charge, as shown in fig. 1-fig. 3, including mold core 1, the system has product die cavity 2 on the core, has injection moulding's product 3 in the product die cavity, core 1 in set up two huff runners and insert 5, respectively set up half slit ox horn runner 6 on two huff runners insert 5 lateral walls in opposite directions, two halves slit ox horn runner 6 make up into a complete ox horn runner, set up U type runner 7 on one of them huff runner inserts, set up sprue 9 and cold charge runner 8 on another huff runner inserts, the ox horn runner is located between U type runner 7 and the cold charge runner 8, sprue 9, U type runner 7, ox horn runner, cold charge runner 8 and die cavity 2 are linked together. The scheme is mainly characterized in that two half gate inserts 5 are arranged in a core 1, half ox horn gates 6 are respectively arranged on opposite side walls of the two half gate inserts 5, a U-shaped runner 7 is arranged on one of the half gate inserts, a main runner 9 and a cold runner 8 are arranged on the other half gate insert, the main runner 9, the U-shaped runner 7, the ox horn gates, the cold runner 8 and a cavity 2 are communicated, a nozzle of a mold is opposite to the main runner 9 during injection, injected plastic raw materials flow into the U-shaped runner 7 through the main runner 9 and then flow into the ox horn gates, but the ox horn gates are hidden gates and downward gates, so that when plastic raw materials flow to the place, the plastic raw materials directly flow into the ox horn gates first and then flow back into the cold runner, and are finally injected into the cavity 2 of a product, and the plastic raw materials are injected first, namely, the semi-solidified plastic raw material at the head part of the sprue is remained in the cold material runner and cannot be injected into the product mold cavity 2, so that the product quality is ensured. The side edges of the two half gate inserts 5 are provided with a convex block 10, the convex block is provided with a transition cavity 11, the ox horn gate is communicated with the transition cavity 11, the transition cavity 11 is matched with the product cavity 2, and the transition cavity is arranged, so that the ox horn gate is tightly connected with the cavity without glue leakage. And after the mold is opened, the ejector pins are driven by power to eject the main runner, the cold material runner and the U-shaped runner out of the mold. The two half gate inserts 5 are provided with fixing holes 13, the fixing holes are provided with screws 15, and the screws are fixedly connected with the mold core 1, so that the installation is convenient and firm.
