Description

Diving gate structure

Technical Field

The utility model relates to the field of molds, especially, relate to a dive runner structure.

Background

The structure of a submarine gate is a very important part of the existing injection mold, and patent CN206306366U provides a submerged nozzle ejection mechanism of the mold, referring to fig. 1 and fig. 2 of the document, because the submarine gate of the existing mold is arranged between a front mold and a rear mold, after the injection molding is completed, a nozzle piece (reference number 3 in the document) is formed, and after the front mold and the rear mold are demolded, the nozzle piece still remains on the rear mold, and the nozzle piece can be detached from the rear mold only by the action of an ejector pin (reference number 2 in the document).

SUMMERY OF THE UTILITY MODEL

The utility model provides a to above-mentioned problem, a dive runner structure is proposed.

The utility model adopts the following technical scheme:

the utility model provides a dive runner structure, includes front mould and back mould, the front mould can be dismantled with the back mould and cooperate together, formed the die cavity between back mould and the front mould, still include the runner mold insert, be provided with the runner on the runner mold insert, be provided with the feed channel on the front mould, runner UNICOM feed channel and die cavity, the runner mold insert detachably install on the front mould.

Through increasing the runner mold insert in this structure to with the runner setting at the runner mold insert, though at the mould injection moulding production completion back, can form the mouth of a river piece in the runner, because the mouth of a river piece is located the runner mold insert, when the front mould breaks away from with the back mould like this, the mouth of a river piece can break away from the injection molding automatically, need not the thimble and pushes up away from the mouth of a river piece.

And when the sprue part needs to be taken out, the sprue part (positioned in the sprue and the feeding channel) can be taken out from the front mold and the sprue insert only by detaching the sprue insert from the front mold. And the gate insert can be replaced quickly when damaged.

Optionally, the gate insert is detachably and fixedly mounted on the front mold by bolts or screws.

Optionally, the feeding channel is in a circular truncated cone shape.

Optionally, the gate is conical, and the gate is inclined with respect to the feed channel.

The feed channel and the runner of above-mentioned structure can reduce the degree of difficulty of taking out the mouth of a river piece, and when the mouth of a river piece was taken out to needs, only need draw the mouth of a river piece at the opening part of feed channel, can take out the mouth of a river piece from runner and feed channel in, it is more convenient to take out the mouth of a river piece.

Optionally, the gate insert is L-shaped, and one end of the gate insert is embedded in the front mold.

One end of the sprue insert is embedded into the front mold, so that the installation stability can be improved.

Optionally, the front mold is a square front mold, and the rear mold is a square rear mold.

Optionally, a feeding pipeline is connected to the front mold, and the feeding pipeline is communicated with the feeding channel.

Optionally, the front mold is a metal front mold, and the rear mold is a metal rear mold.

The utility model has the advantages that: the water gap part can be separated from the injection molding part without an ejector pin in the demolding, and the operation is convenient.

Description of the drawings:

figure 1 is a schematic diagram of a diving gate configuration,

figure 2 is a schematic view of the position of the gating insert and the feed tube,

fig. 3 is a schematic view of the operation principle of the diving gate structure.

The figures are numbered: 1. feed pipe, 2, front mould, 201, feed channel, 3, back mould, 4, nozzle part, 5, injection molding, 6, runner insert, 601, runner, 7, screw.

The specific implementation mode is as follows:

the present invention will be described in detail below.

As shown in fig. 1, fig. 2 and fig. 3, a diving gate 601 structure comprises a front mold 2 and a rear mold 3, wherein the front mold 2 and the rear mold 3 are detachably matched together, a cavity is formed between the rear mold 3 and the front mold 2, the diving gate structure further comprises a gate insert 6, a gate 601 is arranged on the gate insert 6, a feeding channel 201 is arranged on the front mold 2, the gate 601 is communicated with the feeding channel 201 and the cavity, and the gate insert 6 is detachably mounted on the front mold 2.

Through increasing runner mold insert 6 in this structure to set up runner 601 at runner mold insert 6, though after the mould injection moulding production is accomplished, can form mouth of a river piece 4 in runner 601, because mouth of a river piece 4 is located runner mold insert 6, like this when front mould 2 breaks away from with back mould 3, mouth of a river piece 4 can break away from injection molding 5 automatically, need not the thimble and pushes up and leave mouth of a river piece 4.

In addition, when the sprue 601 needs to be taken out, the sprue 4 (located in the sprue 601 and the feed channel 201) can be taken out from the front mold and the sprue insert 6 only by detaching the sprue insert 6 from the front mold 2. And the gate insert 6 can be replaced quickly when damaged.

As shown in fig. 1, 2 and 3, the gate insert 6 is detachably fixed to the front mold 2 by bolts or screws 7.

As shown in fig. 1, fig. 2 and fig. 3, the feeding channel 201 is in the shape of a circular truncated cone.

As shown in fig. 1, 2 and 3, the gate 601 has a conical shape, and the gate 601 is inclined with respect to the feed passage 201.

The feed channel 201 and the runner 601 of the structure can reduce the difficulty of taking out the water gap piece 4, when the water gap piece 4 needs to be taken out, the water gap piece 4 only needs to be pulled at the opening of the feed channel 201, the water gap piece 4 can be taken out from the runner 601 and the feed channel 201, and the water gap piece 4 is taken out more conveniently.

As shown in fig. 1, 2 and 3, the gate insert 6 has an L-shape, and one end of the gate insert 6 is fitted into the front mold 2.

The gate insert 6 is embedded at one end in the front mold 2 to improve the mounting stability.

As shown in fig. 1, 2 and 3, the front mold 2 is a square front mold 2, and the rear mold 3 is a square rear mold 3.

As shown in fig. 1, fig. 2 and fig. 3, the front mold 2 is connected with a feeding pipe 1, and the feeding pipe 1 is communicated with a feeding channel 201.

As shown in fig. 1, 2 and 3, the front mold is a metal front mold, and the rear mold is a metal rear mold.

The above only is the preferred embodiment of the present invention, not therefore the limitation of the patent protection scope of the present invention, all applications the equivalent transformation made by the content of the specification of the present invention, directly or indirectly applied to other related technical fields, all included in the protection scope of the present invention.
