Abstract
The utility model discloses a balanced ejection runner crochet structure, which comprises: the mold comprises an upper mold, a lower mold, a mold core, a runner, a ox horn runner and a runner crochet, wherein the upper mold and the lower mold are mutually buckled, the mold core is arranged between the upper mold and the lower mold, the runner is arranged on the mold core, the ox horn runner is arranged on one side of the runner, and the runner crochet is arranged on the other side of the runner. According to the utility model, the runner crochet hook is arranged on one side of the runner opposite to the ox horn runner, so that the runner is hooked by the runner crochet hook in the ejection process, and when the ox horn runner is continuously ejected, balanced stress is generated on two sides of the runner, and finally, the whole runner can be ejected smoothly to complete ejection action. Compared with the traditional processing means, the runner hook needle is adopted to hook the runner, so that the stress balance mode is adopted, the processing difficulty is low, the installation and maintenance are convenient, and the processing cost is greatly reduced.
Description
Technical Field
The utility model relates to the technical field of production and processing of injection molds, in particular to a runner crochet hook structure capable of balancing ejection.
Background
Referring to fig. 1, in the current ejection structure of the runner ejector pins on the mold of most ox horn runners 01, a manner of adding a diving dummy runner 02 is generally adopted to achieve the effect of balancing the whole runner during ejector pin ejection. However, the method for manufacturing the diving false runner 02 is complex, the electrode is required to be disassembled and then is processed, and the purpose of manufacturing the diving false runner 02 can be achieved by discharging the workpiece through the electrode, so that the operation is complex, and the cost is relatively high.
Accordingly, the prior art has drawbacks and needs improvement.
Disclosure of utility model
The utility model aims to overcome the defects of the prior art and provides a runner crochet hook structure capable of balancing ejection.
The technical scheme of the utility model is as follows: the utility model provides a balanced ejecting runner crochet structure which characterized in that includes: the mold comprises an upper mold, a lower mold, a mold core, a runner, a ox horn runner and a runner crochet, wherein the upper mold and the lower mold are mutually buckled, the mold core is arranged between the upper mold and the lower mold, the runner is arranged on the mold core, the ox horn runner is arranged on one side of the runner, and the runner crochet is arranged on the other side of the runner.
Further, the top of the runner crochet hook is of an inverted buckle structure.
Further, a hanging table is arranged at the bottom of the runner crochet hook.
Further, the lower die is provided with an ejector plate, the ejector plate comprises an ejector plate panel and an ejector plate bottom plate, and the bottom hanging table of the runner crochet hook is embedded in the ejector plate panel and is pressed through the ejector plate bottom plate.
Further, the lower die is provided with a thimble, and the thimble is arranged at a position corresponding to the material injection port of the runner.
By adopting the scheme, the runner crochet hook is arranged on one side of the runner opposite to the ox horn runner, so that the runner is hooked by the runner crochet hook in the ejection process, and when the ox horn runner is continuously ejected, balanced stress is generated on two sides of the runner, and finally, the whole runner can be ejected out smoothly to complete the ejection action. Compared with the traditional processing means, the runner hook needle is adopted to hook the runner, so that the stress balance mode is adopted, the processing difficulty is low, the installation and maintenance are convenient, and the processing cost is greatly reduced.

Detailed Description
The utility model will be described in detail below with reference to the drawings and the specific embodiments.
Referring to fig. 2 and 3, the present utility model provides a balanced-ejection runner hook structure, which is characterized by comprising: the mold comprises an upper mold 11, a lower mold 12, a mold core 3, a runner 4, a ox horn runner 41 and a runner hook 5, wherein the upper mold 11 and the lower mold 12 are mutually buckled, the mold core 3 is arranged between the upper mold 11 and the lower mold 12, the runner 4 is arranged on the mold core 3, the ox horn runner 41 is arranged on one side of the runner 4, and the runner hook 5 is arranged on the other side of the runner 4. Through setting up runner crochet hook 5 on the opposite side of runner 4 with ox horn runner 41 to in ejecting in-process, hook the runner through runner crochet hook 5, when making continue ejecting ox horn runner 41, produce balanced atress in the both sides of runner 4, can be smooth with whole runner 4 all ejecting in order to accomplish ejecting action finally. Compared with the traditional processing means, the runner 4 is hooked by the runner crochet hook 5, so that the stress balance mode is adopted, the processing difficulty is low, the installation and maintenance are convenient, and the processing cost is greatly reduced.
The top of runner crochet hook 5 is back-off structure 51 to the runner 4 sizing material that produces in the injection molding process is buckled, so that hook runner 4 through back-off structure 51 in ejecting process, satisfy ejecting process stress balance's demand.
The bottom of the runner crochet hook 5 is provided with a hanging table 52. The lower die 12 is provided with a thimble plate 6, the thimble plate 6 comprises a thimble panel 61 and a thimble bottom plate 62, and the bottom hanging table 52 of the runner hook 5 is embedded in the thimble panel 61 and is tightly pressed through the thimble bottom plate 62, so that the runner hook 5 is fixed. The lower die 12 is provided with a thimble 7, and the thimble 7 is arranged at a position corresponding to the material injection port of the runner 4, so as to improve the balance of the runner 4 in the ejection process. The runner crochet 5 and the thimble 7 are arranged on the thimble plate 6, so that the runner crochet 5 and the thimble 7 keep a relatively static position in the ejection process of the thimble 7, and the stress balance of the runner 4 in the ejection process is effectively ensured.
In summary, according to the utility model, the runner hook needle is arranged on one side of the runner opposite to the ox horn runner, so that the runner is hooked by the runner hook needle in the ejection process, and when the ox horn runner is continuously ejected, balanced stress is generated on two sides of the runner, and finally, the whole runner can be ejected smoothly to complete the ejection action. Compared with the traditional processing means, the runner hook needle is adopted to hook the runner, so that the stress balance mode is adopted, the processing difficulty is low, the installation and maintenance are convenient, and the processing cost is greatly reduced.
The foregoing description of the preferred embodiment of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
