Description

A sloped top structure of a plastic mold

technical field

The utility model belongs to the technical field of abrasive tools, in particular to a slanted top structure of a plastic mould.

Background technique

Mold refers to various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "mother of industry", it is a tool for turning blanks into workpieces with specific shapes and sizes under the action of external forces. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing.

The inclined top of the mold is also known as the inclined tip. The inclined top is a common saying in the mold industry in the Pearl River Delta region dominated by Hong Kong-funded mold factories. It is a mechanism used to shape the internal barbs of the product in mold design. It is suitable for relatively simple barbs. .

However, there are still some unreasonable factors in the use of the existing sloping roof structure of the plastic mold. The slanting roof structure of the existing plastic mold is not strong enough when used, which leads to frequent damage and is not particularly convenient to use. .

Utility model content

The purpose of this utility model is to provide a slanted roof structure for plastic molds to solve the problem that the existing slanted roof structure for plastic molds proposed in the background technology is not strong enough to cause frequent damage and is not special when used. matter of convenience.

In order to achieve the above purpose, the utility model provides the following technical solutions: a slanted roof structure of a plastic mold, including a pusher plate, a ejector pin fixing plate is arranged above the pusher plate, and the inside of the ejector pin fixing plate is arranged There is a slanted top seat, a slanted roof structure is arranged above the slanted top seat, a slanted top rod is arranged on the slanted top structure, a slanted top guide block is arranged above the slanted top rod, and the top of the slanted top rod An inclined ejector rod head is provided, a backing plate is arranged above the ejector rod fixing plate, a core is arranged above the backing plate, a die is arranged above the die core, and a die is arranged inside the die Plastic parts.

Preferably, the inclined ejector rod has a thin upper part and thicker bottom part, and the outer diameter of the top of the inclined ejector rod is similar to the inner diameter of the inclined ejector guide block.

Preferably, the inclined ejector rod is fixedly connected through the cooperation of the inclined ejector guide block and the inclined ejector seat.

Preferably, the tip of the jacking rod is thick at the top and thin at the bottom, and the outer diameter of the bottom of the jacking rod head is similar to the inner diameter of the guide block of the jacking jack.

Preferably, the inclined ejector rod is fixedly connected with the inclined ejector seat through a pin shaft.

Compared with the prior art, the beneficial effects of the utility model are: the structure of the utility model is scientific and reasonable, and it is safe and convenient to use. In addition, without affecting the upward movement of the slanting roof structure, it has been thickened. The thickened slanting ram and slanting head are more sturdy to use, and will not be easily damaged as the use time increases. The situation is more convenient to use, and it also solves the problem that the inclined roof structure of the existing plastic mold is not strong enough when it is used, which leads to frequent damage and is not particularly convenient to use.
