Description
Technical Field
The utility model belongs to the technical field of the mould, especially, relate to an injection mold gate mould inscribe mechanism.
Background
All design into direct overlap joint when general car function piece product design is glued the mouth and advance the packing that glues and realize the product, the product is glued the mouth and will be even on the product like this, so must adopt secondary manual work or mechanical hand processing just can accomplish this product process, direct overlap joint advances to glue when not designing mould internal cutting mechanism, the mouth is glued to follow-up needs the manual work to repair, general injection molding machine need prepare a personnel and repair the mouth, so just need input equipment or manual work earlier stage, can increase the manufacturing cost of product like this and reduce production efficiency.
The structure of the existing mold is shown in figure 1, when a product is produced, molten plastic in an injection molding machine enters a mold runner system through a cold runner system of the mold, then is shunted to a mold cavity of the mold through a runner for molding, the mold is opened after being cooled, the product is ejected through an ejection system, a workpiece is taken out, the mold is closed, and the product enters a circulating system for producing the product. The original direct lapping glue inlet is connected with the product, the product and the glue inlet are ejected and fall off together during ejection, and the product glue inlet is taken by a mechanical arm and repaired manually.
Disclosure of Invention
The utility model aims to solve the technical problem that an injection mold die inner cutting mechanism is provided realizes the separation of cutting off of jiao kou and product, is favorable to improving product production efficiency and reduces the cost of labor.
The utility model provides a technical scheme that its technical problem adopted provides an injection mold jiao kou mould inscribe mechanism, including preceding template, back template, preceding mold core and back mold core, preceding mold core sets up in the front on the template, back mold core sets up in the back template, during the compound die form the product shaping die cavity between preceding mold core and the back mold core, still include cylinder and gel-cutting mouth blade, the cylinder is installed inside the back template, the gel-cutting mouth blade is installed on the telescopic shaft of cylinder, it sets up corresponding with the jiao kou position that advances of product shaping die cavity to cut the gel-cutting mouth blade, the air cock joint of cylinder sets up in the side of back template.
And mounting cavities of air cylinders are arranged in the rear template and the rear template core.
The rear mold core is provided with a blade guide hole, the position of the blade guide hole corresponds to the position of a glue inlet of the product molding mold cavity, the blade guide hole is communicated with the installation cavity, and the glue cutting blade is arranged in the blade guide hole and is driven by an air cylinder to move along the blade guide hole in a telescopic mode.
Advantageous effects
The utility model discloses an at inside increase mould internal cutting rubber coating machine construct of mould, can drive behind the die sinking and cut the jiao kou blade and stretch out and cut off jiao kou and product, realize the separation that cuts off of jiao kou and product, need not artificial jiao kou work of cutting, be favorable to improving product production efficiency and reduce the cost of labor.

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 and 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 of the appended claims.
The inner cutting mechanism of the plastic mouth mold of the injection mold shown in fig. 2 comprises a front template 1, a rear template 2, a front mold core 3, a rear mold core 4, a cylinder 5 and a plastic mouth cutting blade 6.
The front mold core 3 is arranged on the front mold plate 1, the rear mold core 4 is arranged on the rear mold plate 2, and a product molding mold cavity is formed between the front mold core 3 and the rear mold core 4 during mold closing. The rear die plate 2 and the rear die core 4 are internally provided with an installation cavity of the air cylinder 5, and the air cylinder 5 is installed inside the rear die plate 2 and the rear die core 4.
The rear mold core 4 is provided with a blade guide hole, the position of the blade guide hole corresponds to the position of a glue inlet of a product molding mold cavity, and the blade guide hole is communicated with the installation cavity. The rubber cutting blade 6 is arranged in the blade guide hole, and the rubber cutting blade 6 is installed on a telescopic shaft of the air cylinder 5 and is driven by the air cylinder 5 to move in a telescopic mode along the blade guide hole. And an air nozzle joint 7 of the air cylinder 5 is arranged on the side surface of the rear template 2.
When the product 8 is produced, molten plastic in an injection molding machine enters a mold runner system through a cold runner system of a mold, then is shunted into a mold cavity of the mold through a runner for molding, and is cooled and then opened; then the air is connected through an air nozzle joint 7, so that the air enters the air cylinder 5 through an air pipe, and the air cylinder 5 drives the rubber opening cutting blade 6 to move upwards to separate the rubber opening from the product 8; maintaining pressure of an oil cylinder, opening the die, ejecting a product through an ejection system, taking the product, returning the oil cylinder, closing the die, and entering a circulating system to produce the product. Through the circulation system, the product is perfectly separated from the glue opening, so that the manual glue opening cutting is avoided.
