Description

Convenient ejecting ring flange mould

Technical Field

The invention relates to the technical field of flange molds, in particular to a flange plate mold convenient to eject.

Background

At present, the mold is various molds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".

The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level.

In the casting process, the surface is rough and unsmooth, so that the surface is adhered to the inner wall of the mold, the mold can be taken off only by knocking the mold by using a hammer and other objects under the condition of manual demolding, and the method is time-consuming and labor-consuming and is easy to damage the mold.

The person skilled in the art is dedicated to solving the above technical drawbacks.

Disclosure of Invention

In view of the above-mentioned defects in the prior art, the technical object of the present invention is to provide a flange mold which is easy to eject, is easy to demold, can quickly and completely remove the mold, and ensures the mold to be intact, so as to solve the above-mentioned defects in the background art.

In order to achieve the technical purpose, the invention provides a flange plate die convenient to eject, which comprises a die frame, wherein a prefabricated groove is formed in the top of the die frame, a motor is fixedly arranged inside the die frame, a power output end of the motor penetrates through the prefabricated groove and is fixedly connected with a round pipe, a square groove is formed in the top of the round pipe, a hydraulic cylinder is fixedly arranged inside the square groove, a power output end of the hydraulic cylinder is fixedly connected with a top cover, a plurality of round rods are fixedly arranged at the bottom of the top cover, a fixing plate is further fixedly arranged on the inner wall of the square groove, a through hole is formed in the fixing plate, a power output end of the hydraulic cylinder penetrates through the through hole, an extension spring is fixedly arranged at the top of the fixing plate, and the top of the extension spring.

Further, the top of pipe is the rectangle structure, the bottom of top cap seted up with pipe assorted recess.

Furthermore, the round rods are annularly arranged by taking the round pipe as the center of a circle.

Further, the top cover and the die frame are both of a circular structure.

The invention has the beneficial effects that: the demolding is convenient, the mold can be completely taken off quickly, and the mold is ensured to be intact.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the structure of the top cover of the present invention.

Reference numbers in the figures: 1 mould frame, 2 prefabricated grooves, 3 motors, 4 round tubes, 5 square grooves, 6 hydraulic cylinders, 7 top covers, 8 round rods, 9 fixed plates and 10 extension springs.

Detailed Description

The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, the features and the effects of the present invention.

Example (b):

please refer to fig. 1-2, which illustrates a flange mold facilitating ejection, comprising a mold frame 1, wherein a prefabricated groove 2 is formed at the top of the mold frame 1, a motor 3 is fixedly installed inside the mold frame 1, a power output end of the motor 3 penetrates through the prefabricated groove 2 and is fixedly connected with a circular tube 4, a square groove 5 is formed at the top of the circular tube 4, a hydraulic cylinder 6 is fixedly installed inside the square groove 5, a power output end of the hydraulic cylinder 6 is fixedly connected with a top cover 7, the top cover 7 and the mold frame 1 are both in a circular structure, a plurality of round rods 8 are fixedly installed at the bottom of the top cover 7, it is worth noting that the round rods 8 are annularly arranged by taking the circular tube 4 as a circle center, a fixing plate is fixedly installed on the inner wall of the square groove 5, a through hole is formed in the fixing plate, and the power output end of the hydraulic, the top fixed mounting of fixed plate has extension spring 10, extension spring 10's top fixed connection top cap 7's bottom, and it is worth noting that the top of pipe 4 is the rectangle structure, the bottom of top cap 7 seted up with pipe 4 assorted recess.

During the drawing of patterns, at first through hydraulic cylinder 6 with top cap 7 jack-up for top cap 7 breaks away from with the mould, then hydraulic pressure pinches and just stops work 6, can pull back top cap 7 to initial position through extension spring 10, then motor 3 drives pipe 4 and the motion of round bar 8, and the mould will rotate at prefabricated groove 2 like this, breaks away from with the inner wall of mould frame 1, and the complete harmless drawing of patterns of realization that just so can be very convenient.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts.
