Description

A kind of injection mold with inclined top guide rod

technical field

The utility model relates to injection mold technology, in particular to an injection mold with a slanted top guide rod.

Background technique

Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to injecting heated and melted materials into a mold cavity under high pressure, and after cooling and solidifying, molded products are obtained.

Injection molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc. Among them, the hot pressing mold can be divided into three types: overflow type, semi-overflow type and non-overflow type according to the overflow method. The injection mold consists of a moving mold and a fixed mold. The moving mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine.

At present, it is widely used in the structure of the slanted roof with a large slant on the mold. Only one slanted rod is directly ejected. The roof cannot slide smoothly, resulting in deformation of the vacant part due to high force, causing the slanted roof to be stuck in the mold. The service life of the slanted roof is short and often needs to be replaced, which makes the work cumbersome, increases costs, and wastes production time.

Therefore, in view of the above aspects, it is necessary to make reasonable improvements to the prior art.

Utility model content

In view of the above defects, the utility model provides an injection mold with a guide rod for the inclined roof, which is beneficial to increase the angle of inclination, which can make the force of the inclined roof uniform, and which can be used for a longer period of time during the ejection process of the inclined roof, so as to solve the problems of the prior art. many shortcomings.

In order to achieve the above object, the utility model adopts the following technical solutions:

An injection mold with a slanted top guide rod, comprising a movable mold and a fixed mold, the fixed mold and the movable mold are respectively arranged on the upper and lower sides of the mould, the outer frame of the movable mold is fixed by a movable mold fixing plate, and the fixed mold is fixed. The outer frame of the mold is fixed by the fixed mold fixed plate, and the inclined top mechanism is installed between the fixed mold and the movable mold. There is a bottom plate under the inclined top mechanism, and a fixed seat groove is set on the bottom plate to fix the guide rod fixed seat;

The middle section of the inclined ejector rod of the inclined ejector mechanism is provided with a guide block and the guide block is connected to one end of the guide rod through a pin, and the lower end of the inclined ejector rod of the inclined ejector mechanism is connected to the guide slide seat between the thimble panel and the thimble bottom plate , the lower end of the tilting rod of the tilting mechanism is fixed by the sliding seat of the tilting top;

The guide rod is divided into three sections and fixed. The middle section of the guide rod is fixed on the guide rod sliding seat and installed in the guide slide seat together. The lower end of the guide rod is fixed on the guide rod fixing seat through a pin and installed together. It is arranged on the bottom plate; the two ends of the guide rod are provided with semicircular arc grooves.

Correspondingly, the moving mold fixing plate is composed of a fixing frame, a guide groove and some screws;

Wear-resistant blocks are arranged in the respective guide chute of the guide rod sliding seat and the inclined top sliding seat;

The thimble panel and the thimble bottom plate have guide slide grooves.

The beneficial effect of the injection mold with inclined top guide rod described in the utility model is:

First of all, by setting the guide bar on the inclined roof, it ensures the force balance and smooth sliding when the inclined roof is ejected again, which can prevent the deformation caused by uneven force on the inclined roof and achieve the purpose of long-term use;

Specifically, the injection mold includes a moving mold, a fixed mold and an inclined roof. The movable mold can be opened and closed with the fixed mold through the movable side of the injection molding machine, and the inclined roof can be opened and closed through the injection molding machine. The design of guide rods on the inclined roof can realize the inclined angle of the inclined roof exceeding 15°, which solves the phenomenon that the inclined roof is not uniformly stressed during the ejection process due to the excessive inclination angle, so that the inclined roof cannot slide smoothly, thus The inclined roof is balanced in force, which increases the durability of the inclined roof.
