Description

Water gap ejection structure

Technical Field

The utility model relates to an injection mold technical field, specifically speaking relates to an ejecting structure in mouth of a river.

Background

When injection mold shaping, need simultaneously ejecting with the mouth of a river during product demoulding, set up the mouth of a river thimble in sprue department usually, when the ejecting subchannel of mouth of a river thimble, because of product and runner are at ejecting in-process, can continue the cooling shrink, lead to the cold burden well to glue on the mouth of a river needle, when the manipulator absorbs the product, the cold burden well is extracted unsmoothly, need great power just can extract, the product easily produces deformation, easily lead to the product to inhale simultaneously and can not live and drop, cause the machine halt midway, influence production quality and production efficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mouth of a river is ejecting structure, and the cold burden well is ejecting convenient, improves demolding efficiency and demolding quality.

The utility model discloses an ejecting structure in mouth of a river adopts's technical scheme is:

the utility model provides a mouth of a river ejecting structure, includes the B board and locates inserting on the B board, be equipped with sprue way mouth and subchannel on inserting, insert and seted up the through-hole in sprue way mouth position, be equipped with in the through-hole and inlay the needle, it is equipped with the fixed block to inlay between needle and the B board, first thimble hole and second thimble hole have been seted up respectively to the B board and insert in inlaying the needle both sides, be equipped with first thimble and second thimble in first thimble hole and the second thimble hole respectively.

Preferably, the top of the insert pin is conical.

Preferably, the upper end surfaces of the first thimble and the second thimble are planes.

The utility model discloses an ejecting structure in mouth of a river's beneficial effect is: and after the injection molding of the product is finished, opening the mold, and ejecting the first ejector pin and the second ejector pin on the B plate and the insert outwards. The first ejector pin and the second ejector pin eject cold materials of the flow channel of the sub-flow channel, and meanwhile, the cold material well on the insert pin is also ejected out of the flow channel, so that the cold material well is effectively prevented from being stuck on the insert pin, a product is smoothly demoulded, and the demould efficiency and the demould quality are improved.

Drawings

Fig. 1 is the structure schematic diagram of the nozzle ejection structure of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, a nozzle ejection structure includes a B plate 10 and an insert 20 disposed on the B plate 10, the insert 20 is provided with a main runner port 21 and a branch runner port 22, the insert 20 is provided with a through hole at the position of the main runner port 21, an insert pin 30 is disposed in the through hole, a fixed block 40 is disposed between the insert pin 30 and the B plate 10, the B plate 10 and the insert 20 are respectively provided with a first thimble hole and a second thimble hole at two sides of the insert pin 30, and the first thimble hole and the second thimble hole are respectively provided with a first thimble 50 and a second thimble 60. The insert pin 30 has a conical top. The upper end surfaces of the first thimble 50 and the second thimble 60 are flat surfaces. The top of the insert pin 30 is conical, which is convenient for the cold material well to separate from the insert pin 30. The upper end surfaces of the first thimble 50 and the second thimble 60 are planes, and when the first thimble 50 and the second thimble 60 eject the cold material of the runner, the adsorption force of the cold material of the runner on the first thimble 50 and the second thimble 60 is reduced, so that the first thimble 50 and the second thimble 60 are smoothly separated from the cold material of the runner of the sub-runner 22. The position of the insert pin 30 is fixed, so that the cold material well is conveniently separated.

In the above scheme, after the product injection molding is completed, the mold is opened, and the first ejector pins 50 and the second ejector pins 60 on the B plate 10 and the insert 20 are ejected outwards. The first ejector pin 50 and the second ejector pin 60 eject the cold material of the runner of the sub-runner 22, and the cold material well on the insert pin 30 is also ejected out of the runner, so that the cold material well is effectively prevented from sticking the insert pin 30, the product is smoothly demoulded, and the demould efficiency and the demould quality are improved.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
