Description

A plastic mold with anti-adhesion and high corrosion resistance

technical field

The invention belongs to the technical field of plastic molds, in particular to a plastic mold with high anti-adhesion and corrosion resistance.

Background technique

Plastic molds are tools that are matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise dimensions. Due to the variety of plastics and processing methods, and the structures of plastic molding machines and plastic products, the types and structures of plastic molds are also varied. A plastic mold is a tool for producing plastic products. It consists of several groups of parts, and this combination has a molding cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and cooled and shaped in the cavity, then the upper and lower molds are separated, and the product is ejected from the cavity through the ejector system to leave the mold, and finally the mold is closed again For the next injection molding, the entire injection molding process is carried out in a cycle.

Existing plastic molds are easily corroded during work, which shortens the service life of the plastic mold, and the workpiece is also easy to adhere to the punch. Therefore, we propose a plastic mold with anti-adhesion and high corrosion resistance.

In order to achieve the above object, the present invention provides the following technical solutions: a plastic mold with high anti-adhesion and corrosion resistance, including a plastic mold base, a mold base bracket is arranged on the lower right side of the plastic mold base, and the inside of the plastic mold base A hydraulic pump is provided at the end of the left side away from the mold base bracket, and a hydraulic telescopic rod is provided on the right side of the hydraulic pump close to the middle position inside the plastic mold base, and a plastic mold is provided at the middle position above the plastic mold base. Outer casing, a plastic working area is provided at the middle position inside the outer casing of the plastic mold, a protective layer is provided on the outer wrapping of the plastic working area, a workpiece release device is arranged on the upper right of the outer casing of the plastic mold, and the A punch is arranged above the hydraulic telescopic rod close to the left side of the workpiece release device, a punch seat is arranged above the punch, and a punch seat installation port is arranged on the right side of the punch seat close to the upper right of the punch , the hydraulic pump is electrically connected to an external power supply.

Preferably, there are four mold base supports in total, and the four mold base supports are respectively installed on both sides below the plastic mold base.

Preferably, there are two workpiece release devices in total, and the two workpiece release devices are respectively installed on both sides above the outer shell of the plastic mold.

Preferably, the hydraulic pump is fixedly connected to the plastic mold base through bolts.

Preferably, there are two installation ports of the punch seat, and the two installation ports of the punch seat are installed on the left and right sides of the punch seat respectively.

Compared with the prior art, the beneficial effect of the present invention is that the structure of the present invention is scientific and reasonable, and it is safe and convenient to use. A workpiece release device is provided at both ends above the outer casing of the plastic mold. When the punch rises, the workpieces at both ends The release device will extend to block the workpiece, but it will not hinder the rise of the punch, so that the workpiece will not rise with the punch due to adhesion, and a protective layer is set in the plastic working area, which can effectively reduce the impact of the material on the mold. Corrosivity can greatly increase the service life of the machine.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1, the present invention provides a kind of technical scheme: a kind of anti-adhesion and high corrosion resistance plastic mold, comprise plastic mold base 2, the bottom right of plastic mold base 2 is provided with mold base support 1, and plastic mold A hydraulic pump 11 is provided on the left side of the base 2 away from the end of the mold base support 1, and a hydraulic telescopic rod 10 is arranged on the right side of the hydraulic pump 11 close to the middle position inside the plastic mold base 2, and the middle position above the plastic mold base 2 A plastic mold outer shell 9 is arranged at the center of the plastic mold outer shell 9, and a plastic working area 3 is arranged at the middle position inside the plastic mold outer shell 9. The outer wrapping of the plastic working area 3 is provided with a protective layer 4. Disengager 5, the top of the hydraulic telescopic rod 10 is provided with a punch 6 close to the left side of the workpiece disengager 5, the top of the punch 6 is provided with a punch seat 8, and the right side of the punch seat 8 is close to the upper right of the punch 6 A punch seat installation port 7 is provided, and the hydraulic pump 11 is electrically connected with an external power supply.
