TECHNICAL FIELD

[0001] The application belongs to the technical field of molds and relates to a quick opening and closing pull hook safety dryness reduction reset structure. BACKGROUND

[0002] In a hot runner device, the problem to be solved is that in the production process, the needle valve moves for a long time, and there are a lot of material powder on the flow distribution plate, which is difficult to clean. At present, before cleaning such a device, the mold needs to be pulled open through the mold opening structure. Commonly used turnover box molds mostly adopt an oil cylinder opening sliding block structure in terms of structural action. This mechanism has a long cycle, and some customers pursue a short cycle and use a pull hook structure. This mechanism has a significant reduction in cycle, but in the common pull rod pull hook structure, there is transverse friction in the movement direction, and the buffer part has no service life under the friction force. It is impossible to design a buffer spring, and it is impossible to achieve noise reduction. Therefore, it is urgent to design a quick opening and closing pull hook safety dryness reduction reset structure that can overcome the above defects.

[0003] In order to overcome the defects of the prior art, people have constantly explored and proposed various solutions. For example, a meter panel mold pull hook structure is disclosed in Chinese patent [application number: 201711226540.1], which comprises a ejector pin plate, a top block is arranged below the ejector pin plate, a connecting block is arranged on the ejector pin plate, a pull rod is hingedly arranged on the connecting block, a wear-resistant block is arranged on the outer wall of the movable mold, a pull hook is arranged at the end of the pull rod away from the connecting block, a containing groove is arranged on the upper surface of the pull hook, and the wear-resistant block is limited in the containing groove. When the mold is opened, the movable mold moves downward to drive the pull rod to move downward together, so as to drive the ejector pin plate and the inclined ejector pin block to move downward to eject the product. However, in the use process of this scheme, there is still transverse friction in the movement direction, and the buffer part has no service life under the friction force. It is impossible to design a buffer spring, and it is impossible to achieve noise reduction. SUMMARY

[0008] In the quick opening and closing pull hook safety noise reduction reset structure, the upper die is internally provided with a pull hook sliding groove, and the pull hook sliding rod is in sliding fit with the pull hook sliding groove.

[0009] In the quick opening and closing pull hook safety noise reduction reset structure, the screwing piece comprises a first fastening bolt arranged between the pull hook sliding rod and the lower die, and the width of the pull hook protrusion is smaller than the width of the through hole.

[0010] In the quick opening and closing pull hook safety noise reduction reset structure, the flip body is connected with the fixed block through a self-resetting rotary connecting structure, and when the flip body is closed, the flip body and the pull hook sliding rod form a gap.

[0011] In the quick opening and closing pull hook safety noise reduction reset structure, the noise reduction buffer structure comprises two rubber springs arranged on the fixed block, the rubber springs are fixed between the fixed block through screws, and the rubber springs are arranged opposite to the flip body.
