Problems solved by technology

[0003] At present, there is an existing injection mold clamping and holding pressure machine, which continuously and stably delivers gas to the air pressure component through the holding machine, so that the telescopic rod drives the upper mold to press down. , so that when the upper mold is pressed down, one side is high and the other side is low, causing the injection molding raw materials to overflow when the film is combined, resulting in the deformation of the formed product

Abstract

The invention discloses an injection molding mold compounding pressure maintaining machine. The injection molding mold compounding pressure maintaining machine structurally comprises an air cylinder, buttons, a through pipe, a lower mold and supports. The buttons are movably connected to the front side of the air cylinder in a clamped manner, one end of the through pipe is installed on the right side of the air cylinder, the bottom of the lower mold is fixedly embedded in the upper surface of the air cylinder, and the bottoms of the supports are connected to the top of the air cylinder in a welded manner. The injection molding mold compounding pressure maintaining machine has the beneficial effects that air is conveyed into air pressure assemblies through the through pipe, the air pressure of air pressure cavities is increased, telescopic rods are pushed downwards, so that movable plates at the bottoms of upper molds extrude injection molding raw materials, limiting plates are kept horizontal under the elastic force of buffer springs and supporting of fixators, the limiting plates can extrude the injection molding raw materials conveniently, the shrinkage phenomenon is prevented from happening after products are cooled and cured, when the raw materials are extruded and formed, lifting plates are driven by positioning plates to move downwards, positioning rods play a supporting role to avoid shaking, the friction force between anti-skid teeth and the positioning rods is increased under the elastic force of supporting springs, and the slipping phenomenon of anti-slip sleeves and the positioning rods during pressure maintaining mold compounding is avoided.

Description

technical field [0001] The invention relates to the field of equipment for injection mold clamping, in particular to an injection mold clamping and pressure maintaining machine. Background technique [0002] In industrial production, the raw materials are injected into the injection molding tank, and the raw materials are pressed and formed to obtain the desired product after laminating the film. In the process of laminating the film, the air pressure component is controlled by the pressure holding machine to push the upper mold to the lower mold. The speed is the same as The pressure makes the upper mold and the lower mold extrude the raw materials in the injection tank to avoid shrinkage after the product cools and solidifies. [0003] At present, there is an existing injection mold clamping and holding pressure machine, which continuously and stably delivers gas to the air pressure component through the holding machine, so that the telescopic rod drives the upper mold to ...
