Mold with ejector delay needle

Abstract

The invention relates to an injection mold, in particular to a mold with an ejector delay needle, which comprises an upper ejector plate, a lower ejector plate, an ejector and a latent pouring flow passage, wherein one end of the ejector is fixed on the lower ejector plate after penetrating the upper ejector plate; the other end of the ejector is propped against the latent pouring flow passage; the delay needle matched with the ejector is arranged in the lower ejector plate; a cavity for accommodating an end part of the delay needle is arranged in the lower ejector plate; and a clearance is reserved between the end part of the delay needle and the bottom of the cavity. Through the arrangement of the delay needle, when a product is needed to be ejected out, the ejecting out of the ejector in the latent pouring flow passage is delayed under the action of the delay needle, so that the water gap of the latent pouring flow passage is completely separated from a product, the product is prevented from being strained, and workers' overhaul cost is reduced. Moreover, the assembly and the disassembly are convenient; and the processing is simple.

Description

technical field [0001] The invention relates to an injection mold, in particular to a mold with a thimble delay pin. Background technique [0002] In the process of fully automated mechanical production of products, the injection gate of the product is often used as submerged pouring, so as to automatically cut off the water gate during production, saving manpower and reducing the cost of the gate. There must be a thimble under the submerged gate to ensure that the gate is ejected. Since the thimble under the nozzle and the thimble of the ejecting product are fixed on the thimble plate and combined into one, when the product is ejected, the product moves together with the runner of the nozzle. [0003] However, since the runner is submerged pouring, when the products are ejected at the same time, the upper nozzle of the product is obvious, and occasionally there will be residual debris left on the product, which needs to be manually inspected and repaired, and the product w...

[0003] However, since the runner is submerged pouring, when the products are ejected at the same time, the upper nozzle of the product is obvious, and occasionally there will be residues left on the product, which needs to be manually checked and repaired, and the product will occasionally be pulled.
