A plastic mold capable of repeated molding

Plastic mold It is both a tool for manufacturing plastic products and a device that imparts the product with its complete structure and precise dimensions. Plastic molding is a mass‑production process used to fabricate parts with complex geometries. Specifically, molten plastic is injected at high pressure into a mold cavity by an injection molding machine, and after cooling and solidification, the molded part is obtained. Although the mold’s design may vary depending on the type and properties of the plastic, the shape and structure of the molded part, and the model of the injection molding machine, its basic architecture remains consistent. Plastic molds primarily consist of a gating system, a temperature‑control system, molding components, and structural elements. Among these, the gating system and the molding components are in direct contact with the plastic and undergo significant changes along with the material and the final product; they are highly complex, subject to substantial variation, and demand exceptionally high surface finish and dimensional accuracy. Ordinary… Plastic mold It is inconvenient to adsorb and secure dust within the fixed mold, which reduces machining accuracy. During stamping, these components cannot provide adequate cushioning in the fixed mold, leading to a shortened service life, material waste during operation, and difficulty in reuse. Moreover, a single plastic mold cannot be reused for molding, making it unsuitable for both small‑scale and large‑scale production. Accordingly, a new plastic mold has been proposed to address these issues.

Technicians provide a Plastic mold , in order to address the aforementioned issues. This plastic mold is The above objective is achieved through the following technical solution: a plastic mold comprising a workbench, with a support frame and a slide groove fixedly mounted on the top of the workbench; the slide groove is positioned within the support frame. At the end of the support frame remote from the workbench, an upper beam is fixedly attached; a hydraulic cylinder is installed at the top of the upper beam, with its output rod extending through the upper beam and terminating in a welded top plate. A movable mold is fixedly mounted to the underside of the top plate. Below the movable mold is a fixed mold, which is rigidly connected to the base plate inside the slide groove. On one side of the slide groove, an air cylinder is fixedly mounted; the free end of the air cylinder is connected to the output end of an air pump. A sliding rail is provided between the slide groove and the workbench. The air pump is located on the upper surface of a support plate, which is fixedly connected to one end of the workbench; the bottom of the support plate is equipped with an emergency stop button. At the lower end of the top plate, suction covers are fixedly mounted on either side of the movable mold; these covers are connected via branch ducts and a main duct to a dust collection box, with multiple sets of such covers evenly spaced along the fixed mold. A dust collection bin is positioned adjacent to the hydraulic cylinder; its exterior features an access door, and the bin is transparent, with a ventilation opening at one end and an exhaust fan installed inside. The main duct is fixedly connected at its end remote from the dust collection bin to a branch duct; the branch duct, at its end remote from the main duct, passes through the top plate and connects to the upper end of a suction hood. Four pairs of fixed feet are spaced and fixedly attached to the bottom of the workbench, with diagonal braces provided between the feet and the workbench. The slide groove is shaped… “U” The structure comprises a slider that is locked within a slide groove, with the slider rigidly connected to both ends of the base plate. A spring layer is provided beneath the base plate, positioned at the bottom of the slide groove. A collection bin is fixedly mounted to the underside of the workbench, and a valve is installed at the bottom of the collection bin.

The above Plastic mold It has the following beneficial effects:

1 , the plastic mold The structural design is well‑thought‑out. A dust collection box is installed, and a blower is mounted inside it. The blower can move the fixed mold beneath the suction hood via a pneumatic cylinder, allowing dust within the mold to be drawn into the blower. The dust then travels through the main and branch air ducts into the collection box and is discharged through the outlet, effectively and rapidly removing dust from the fixed mold, thereby ensuring machining accuracy and securing the collection box to the mold.

2 , this Plastic mold The cylinder drives a guide rod, which in turn causes the slide groove to reciprocate. Multiple sets of fixed molds are arranged at equal intervals, and a hydraulic cylinder actuates a piston rod to move these molds, facilitating batch positioning. An emergency stop button is provided for precise alignment, enabling repeatable adjustments and enhancing overall functionality; it can be deployed in both small‑scale and large‑scale applications. The slider is securely fastened to the base plate, with its ends engaging with the corresponding slide grooves. U A compliant spring layer is provided at the bottom of the groove, facilitating installation.
