Abstract

The utility model provides an injection mold's runner structure of advancing, including watering runner and model chamber, the model chamber is connected and is equipped with into runner, it is equipped with the lug chamber to water the runner connection, advance the runner with lug chamber intercommunication, it waters liquid process in proper order to water to irritate in the runner the lug chamber arrives it pours into at last to advance the runner the model intracavity. The utility model discloses an injection mold's runner structure that advances, watering liquid in the runner gets into the lug chamber earlier and gets into the runner again, utilizes the lug chamber to play the effect that the buffering was strikeed to watering liquid to having reduced the impact force that gets into the pouring liquid of model intracavity in the runner that advances, having reduced the product defect of final fashioned injection molding, having improved the finished product qualification rate.

Description

Inlet gate structure of injection mold

Technical Field

The utility model belongs to the technical field of the injection mold and specifically relates to an injection mold's runner structure that advances.

Background

The pouring channel is connected to one end of a pouring gate of a traditional injection mold, the other end of the pouring gate is directly connected with the model cavity, pouring liquid is directly poured into the model cavity from the pouring channel through the pouring gate, most of the pouring gates are vertically connected with the model cavity, the large impact force of the pouring liquid directly impacts the surface of an injection molding piece formed in the model cavity when the pouring is carried out by the structure, so that the surface of the injection molding piece formed finally has the defects of punching lines or generating paste spots, and the stress generated inside the injection molding piece easily causes the product deformation and the like, and the finished product percent of pass is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem among the prior art, provide an injection mold's runner structure that advances, get into the impact force of pouring liquid in the model cavity through reducing the runner that advances, reduce the product defect of final fashioned injection molding, improved the finished product qualification rate.

The utility model adopts the technical scheme as follows:

the utility model provides an injection mold's runner structure that advances, is including watering runner and model chamber, the connection of model chamber is equipped with into runner, it is equipped with the lug chamber to water the runner connection, advance the runner with lug chamber intercommunication, it passes through in proper order to water the liquid of watering in the runner the lug chamber arrives it pours into at last to advance the runner the model intracavity.

Furthermore, the lug cavity is provided with more than twice of the volume of the inlet gate.

Furthermore, the lug cavity is provided with one or more than one inlet gate, and the lug cavity is provided with more than two times of total volume of the inlet gate.

Further, the degree of depth in lug chamber is greater than the degree of depth of advancing the runner, advance the runner the upper end with the upper end parallel and level setting in lug chamber.

Furthermore, the pouring channel comprises a main channel and a sub-channel, and the sub-channel is arranged between the main channel and the lug cavity.

Further, the sprue with set up perpendicularly between the subchannel, the subchannel with the equal level setting in lug chamber.

The utility model has the advantages that:

the utility model relates to an injection mold's runner structure that advances, watering liquid in the runner gets into the lug chamber earlier and gets into the runner again, utilizes the lug chamber to play the effect that the buffering was strikeed to watering liquid to having reduced the impact force that gets into the pouring liquid in the model intracavity in the runner that advances, having reduced the product defect of final fashioned injection molding, having improved the finished product qualification rate.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Please refer to fig. 1-4, an embodiment of the present invention discloses an inlet gate structure of an injection mold, including a pouring channel and a mold cavity 2, the mold cavity 2 is connected and provided with an inlet gate 3, the pouring channel is connected and provided with a lug cavity 4, the inlet gate 3 is communicated with the lug cavity 4, pouring liquid in the pouring channel sequentially passes through the lug cavity 4 to the inlet gate 3 and is finally poured into the mold cavity 2.

Further, the lug cavity 4 is provided with more than twice the volume of the inlet gate 3. The volume of the lug cavity 4 is more than twice of the volume of the sprue 3, so that the sprue 3 is ensured not to be influenced by the additionally arranged lug cavity 4.

Furthermore, the lug cavity 4 is provided with one or more inlet gates 3, and the lug cavity 4 is provided with more than two times of the total volume of the inlet gates 3.

Further, the depth of lug chamber 4 is greater than the depth of advancing runner 3, advance the upper end of runner 3 with the upper end parallel and level setting of lug chamber 4. Namely, the bottom of the lug cavity 4 is lower than the bottom of the sprue 3, the pouring liquid can be deposited in the lug cavity 4 for a short time, and the function of separating out impurities is achieved to a certain extent.

Further, the runner includes a main runner 11 and a sub-runner 12, and the sub-runner 12 is disposed between the main runner 11 and the lug cavity 4.

Further, sprue 11 with set up perpendicularly between subchannel 12, subchannel 12 with the equal level setting of lug chamber 4.

To sum up, the utility model relates to an injection mold's runner structure that advances waters pouring gate 3 that water pouring liquid in the runner gets into lug chamber 4 earlier and gets into again, utilizes lug chamber 4 to play the effect that the buffering was strikeed to watering liquid to having reduced the impact force that gets into pouring liquid in the model chamber 2 in advancing pouring gate 3, having reduced the product defect of final fashioned injection molding, having improved the finished product qualification rate.
