Description

Technical Field

[0001] The utility model relates to the technical field of oil hydraulic press molds, in particular to a compression molding mold for medium and large oil hydraulic presses. Background Art

[0002] A hydraulic press is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil is forced into the cylinder or piston through the hydraulic pipeline by the force of the pump. Then, there are several sets of seals in the cylinder or piston that cooperate with each other. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, a one-way valve is used to circulate the hydraulic oil in the oil tank, causing the cylinder or piston to circulate and perform work, thereby completing a certain mechanical action as a kind of productivity. In order to improve the processing efficiency of the hydraulic press, a mold is needed, but the existing mold still has the following shortcomings:

[0003] For example, the utility model with application number 201620249991.1 discloses a hydraulic press mold for shaping large parts. The utility model has a simple and reliable structure, is easy to maintain, and can realize the rapid shaping of large parts. However, similar to the comparative documents of the above-mentioned application, when the existing hydraulic press mold is used, since most hydraulic presses need to replace and install the mold according to the object to be processed before pressing, and the mold is mostly fixed to the hydraulic press by multiple bolts, the replacement of the mold is time-consuming and labor-intensive, and the labor intensity of the staff is increased, resulting in the problem of reduced practicality and reduced utilization efficiency of the hydraulic press mold.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a pressing molding die for medium and large hydraulic presses is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a compression molding die for medium and large-sized hydraulic presses to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compression molding die for medium and large hydraulic presses, comprising a main body and a mounting assembly, a control panel being installed on the right side of the outside of the main body, and a processing cavity being opened in the middle of the inside of the main body, a mounting assembly being provided at the lower end of the inside of the processing cavity, and the mounting assembly comprising a mounting seat, a mounting groove, a mounting block, a mold body, a limiting groove, a pneumatic rod, a clamping block, an anti-slip rubber layer and a limiting block, a mounting groove being opened at the upper end of the inside of the mounting seat, and a mounting block being connected to the inside of the mounting groove, and the mold body being installed at the upper end of the mounting block, while limiting grooves being opened on both sides of the outside of the mold body, pneumatic rods being installed on both sides of the inside of the processing cavity, and a clamping block being installed at the front end of the pneumatic rod, and an anti-slip rubber layer being added to the outside of the clamping block, while a limiting block is installed on the outside of the clamping block.

[0007] Furthermore, a mother-and-child cylinder is provided in the middle of the upper end of the main body, and a pressure plate is installed at the front end of the mother-and-child cylinder. Limiting through holes are provided at the four corners of the outer side of the pressure plate, and a limiting rod is connected inside the limiting through hole.

[0008] Furthermore, the mother-and-child cylinders and the pressure plate are vertically distributed, and the mother-and-child cylinders are threadedly connected to the pressure plate.

[0009] Furthermore, the inner dimension of the limiting through hole matches the outer dimension of the limiting rod, and the pressing plate is slidably connected to the limiting rod through the limiting through hole.

[0010] Furthermore, the inner dimensions of the mounting groove match the outer dimensions of the mounting block, and the mounting block is slidably connected to the mounting seat through the mounting groove.

[0011] Furthermore, the clamping block and the pneumatic rod are distributed vertically, and the clamping block and the pneumatic rod are threadedly connected.

[0012] Furthermore, the clamping block is in an "L" shape, and the outer side of the clamping block is tightly fitted with the outer side of the mold body.

[0013] Furthermore, the outer dimensions of the limiting block match the inner dimensions of the limiting slot, and the limiting block is embedded in the mold body via the limiting slot.

[0014] The utility model provides a compression molding die for medium and large oil hydraulic presses, which has the following beneficial effects:

[0015] 1. The utility model is provided with a limit rod, and when used for the compression molding molds of medium and large hydraulic presses, the limit rod provided inside the processing chamber can be used to prevent the pressure plate of most hydraulic press molds from being easily displaced during the processing, which affects the processing yield and reduces the efficiency of the hydraulic press mold. The mother-and-child cylinder is fixedly installed on the upper end of the main body by fasteners, and the pressure plate is fixedly installed on the front end of the mother-and-child cylinder with the help of fasteners. The operation of the mother-and-child cylinder drives the pressure plate to move its position, and the limit rod is fixedly installed at the four corners inside the processing chamber. At the same time, the internal size of the limit through hole opened inside the pressure plate matches the external size of the limit rod, and then the stability of the pressure plate during movement is increased by cooperating with the limit through hole and the limit rod, thereby avoiding positional displacement of the pressure plate during processing and further improving the processing yield of the hydraulic press.

[0016] 2. The utility model can avoid the need for most hydraulic presses to replace and install the mold according to the object to be processed before pressing through the installation of the mounting assembly when it is used for the compression molding mold of medium and large hydraulic presses. The mold is mostly fixed to the hydraulic press by multiple bolts, which makes the replacement of the mold time-consuming and labor-intensive and increases the labor intensity of the staff, resulting in the problem of reduced practicality of the hydraulic press mold. The mounting seat is fixed to the lower end of the inner part of the processing cavity by tightening the bolts. The internal dimensions of the mounting groove opened in the mounting seat match the external dimensions of the mounting block added at the lower end of the mold body. The mold body is slidably installed into the upper end of the mounting seat through the mounting groove and the mounting block, and the pneumatic rod is fixedly installed on both sides of the lower end of the inner part of the processing cavity. The pneumatic rod operation drives the clamping block to move the position, and cooperates with the non-slip rubber layer to limit the mold body on the mounting seat again. At the same time, the internal dimensions of the limiting grooves opened on both sides of the interior of the mold body match the external dimensions of the limiting blocks installed outside the clamping block, so that when the clamping block limits the mold body, the limiting block is cooperated to avoid position deviation of the mold body, and the installation and replacement efficiency of the mold body is improved, further improving the flexibility and initiative during the use of the hydraulic press mold.
