Abstract

The utility model discloses a mould core vent mainly relates to mould exhaust field. The plug body is a metal powder particle sintered piece; the plug body is provided with a guide part, and the plane of the top of the plug body is flush with the inner surface of the rubber mold in line. An exhaust groove is arranged below the plug body. The beneficial effects of the utility model reside in that: the mechanical exhaust device is not adopted, and exhaust can be performed without arranging an exhaust hole; the mold glue for product molding can not leak during air exhaust, thereby avoiding the formation of burr edges on the surface of the injection mold product in the production process.

Description

Mold vent plug

Technical Field

The utility model relates to a mould exhaust field specifically is a mould core vent.

Background

The existing mold exhaust device is generally a mechanical exhaust device, and the product structure widely used at present is the patent technology shown in CN 201910504263.9. The structure is that the vent holes are provided with assembly parts, so that a plurality of matching sizes exist, the product size is small, and the processing is difficult. And the spring is easy to be fatigued and easy to be blocked, and once the situation of blocking the rubber occurs, the repair is difficult and the replacement is needed. The more serious defect is that the mold glue for product molding leaks into the exhaust holes during exhaust, so that burr edges are formed on the surface of the injection mold product. The burr edges need to be cleaned subsequently, so that the manufacturing procedures of the product are increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a mold vent plug, which can exhaust without adopting a mechanical exhaust device and arranging an exhaust hole; the mold glue for product molding can not leak during air exhaust, thereby avoiding the formation of burr edges on the surface of the injection mold product in the production process.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

a mold vent plug comprises a plug body, wherein the plug body is a metal powder particle sintered piece; the plug body is provided with a guide part, and the plane of the top of the plug body is flush with the inner surface of the rubber mold in line.

An exhaust groove is arranged below the plug body.

The guide part is arranged on the lower portion of the plug body and is in a frustum shape, and a placing hole matched with the frustum-shaped guide part is formed in the rubber mold.

The metal powder particles used for manufacturing the plug body are powder particles of a titanium material or a stainless steel 316L material.

Contrast prior art, the beneficial effects of the utility model reside in that:

1. the plug body of the device is a metal powder particle sintered part, and pressure relief and exhaust are carried out by sintered micropores. The plug body of the technology is integrally sintered, and the micropore gap is used for exhausting gas. The plug body can be installed at any position where air exhaust is needed. The exhaust groove can be installed on the existing mold by changing the structure of the guide part. In addition, the mold is provided with a vent groove to form a convex protrusion representation on the product, and if the vent is needed at the position, the vent can be performed by the plug body of the technology if the convex protrusion representation is not allowed on the product.

2. The combined use principle is described as follows: the gas to be exhausted from the mold is exhausted from the micropores of the plug body to the exhaust groove, so that the gas is exhausted. The purpose of the exhaust groove is to increase the exhaust area, reduce the exhaust pressure and increase the exhaust speed.

1. a plug body; 2. a guide portion; 3. an exhaust groove; 4. placing the holes.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

The utility model relates to a mold vent plug, the main structure of which comprises a plug body 1, wherein the plug body 1 is a metal powder particle sintered part; the metal powder particles used for manufacturing the plug body 1 are powder particles of a titanium material or a stainless steel 316L material. The plug body 1 is provided with a guide part 2, and the top plane of the plug body 1 is flush with the inner surface of the rubber mold in line. An exhaust groove 3 is arranged below the plug body 1. The guide part 2 is arranged on the lower part of the plug body 1 and is in a frustum shape, and a placing hole 4 matched with the frustum-shaped guide part 2 is formed in the rubber mold.

Principle and technical explanation of the present device:

the plug body 1 of the device is a metal powder particle sintered part, and pressure relief and exhaust are carried out by sintered micropores. The plug body 1 of the technology is integrally sintered and exhausts air by utilizing a micropore gap. The plug body 1 can be installed at any position where air exhaust is needed. It is also possible to apply the present invention by changing the structure of the guide portion 2 and attaching the same to the vent groove 3 of the existing mold. In addition, the mold is provided with the vent grooves 3 to form a convex protrusion representation on the product, and if the vent is needed at the position, the vent can be performed by the plug body 1 of the technology if the convex protrusion representation is not allowed on the product. The gas to be exhausted from the mold is exhausted from the micropores of the plug body 1 into the exhaust groove 3, and the high-pressure gas is exhausted. The exhaust groove 3 is provided for increasing the exhaust area, reducing the exhaust pressure, and increasing the exhaust speed.
