Description

Die inclined ejection protection structure

Technical Field

The utility model relates to an injection mold field specifically says a mould pushes up protection architecture to one side.

Background

Some injection mold are in the product shaping after, often need through the kicking block, the thimble is ejecting with the product, the shaping quality of assurance product that just can be better, but because the design of the pipeline of moulding plastics in the mould, there is the condition that is difficult to be vertical setting in kicking block and thimble, and need be the slope setting, and the period is longer when reseing with the thimble of slope setting, can't reset fast, thereby lead to the unable purpose that realizes high-speed production of this mould, perhaps the condition that the defective rate of product is high.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the utility model provides a can incline the ejector pad that sets up and quick the mould of thimble reset in order to improve product production efficiency to push up protection architecture to one side.

The technical scheme adopted by the invention for solving the problems is as follows: the utility model provides a mould pushes up protection architecture to one side, includes front mould benevolence and back mould benevolence, front mould benevolence and back mould benevolence form the die cavity when the compound die, the die cavity is used for the shaping product, be equipped with the kicking block that is used for ejecting back mould benevolence with the product on the back mould benevolence, the thimble that is used for driving the kicking block to remove is connected to the lower extreme of kicking block, be equipped with the cushion on the front mould benevolence, the upper end that the kicking block was located to the cushion is used for resetting the kicking block fast.

Compared with the prior art, the invention has the advantages that: because the ejector block is used for ejecting a formed product, the ejector block is arranged at the bottom of the die cavity, when the die is closed, the upper die core cannot be in contact with the ejector block, so that the ejector block cannot be assisted to reset quickly, if the ejector block does not complete the reset operation before the next injection molding, and after the injection molding material is injected, the product has appearance defects, so that the reject ratio of the product is caused, so that the ejector block can reset quickly, when the die is closed, through the design of the elastic pad, the elastic pad can be in contact with the ejector block to assist the quick reset of the ejector block, meanwhile, because the elastic pad has elastic reasons, the ejector block can reset in advance, and then when the die is closed, the elastic pad cannot interfere the structure after the die is closed under the elastic action, the integrity of the die cavity is ensured, if the ejector pin is designed in an inclined manner, through the design of the elastic pad, a buffer effect can be provided for the reset of the ejector pin, the condition that the thimble is easy to damage due to tangential stress when the thimble resets is avoided.

As an improvement of the invention, one side of the elastic cushion close to the top block is matched with one side of the top block close to the elastic cushion, and the force of the elastic cushion on the top block can be more uniform through the improvement, so that the top block is more stably reset.

As an improvement of the invention, the elastic pad is arranged at one side of the die cavity, one section of the top block is arranged at the bottom of the die cavity, and the other section of the top block is arranged at the bottom of the elastic pad.

As an improvement of the present invention, two mold cavities symmetrically arranged about a symmetry axis are arranged between the front mold core and the rear mold core, and one of the ejector blocks simultaneously acts on the two mold cavities, and the ejector blocks are symmetrically arranged about the symmetry axis.

As an improvement of the invention, one end of the ejector block is arranged at the bottom of one mold cavity, the other end of the ejector block is arranged at the bottom of the other mold cavity, and the ejector pins are arranged on the symmetry axis.

As an improvement of the present invention, two elastic pads are provided, the two elastic pads are both arranged between the two mold cavities, the two elastic pads are symmetrically arranged about the symmetry axis, through the improvement, because the thimble is also arranged on the symmetry axis in the connection process of the thimble and the ejector block, because the thimble is obliquely arranged, the thimble can relatively move with the ejector block in the reset process, if the elastic pads are also arranged on the symmetry axis, the elastic pads and the thimble are easy to interfere, which is not beneficial to the reset of the ejector block, and through the design of the two elastic pads, the interference of the elastic pads and the thimble can be avoided, and simultaneously, the uniformity of the stress of the ejector block can be ensured.

As an improvement of the invention, the front die core is provided with a placing groove for placing the elastic pad, and through the improvement, the elastic pad can be contracted into the placing groove in the die assembly property, so that the elastic pad is prevented from interfering the die assembly.

As an improvement of the invention, the elastic pad is a rubber pad.

As an improvement of the invention, the elastic cushion comprises a cushion block and a spring, one end of the spring is fixedly connected with the cushion block, and the other end of the spring is fixedly connected with the bottom of the placing groove.
