Description

Injection molding mold

technical field

The utility model relates to the technical field of moulds, in particular to an injection molding mould, which saves costs and raw materials.

Background technique

A mold (English name: mold) is a tool that makes a blank into a workpiece with a specific shape and size under the action of external force. Various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry".

The mold has a specific contour or cavity shape, and the application of the contour shape with a cutting edge can separate the blank according to the contour line shape (punching). Applying the shape of the inner cavity can make the blank obtain the corresponding three-dimensional shape. The mold generally includes two parts, the movable mold and the fixed mold (or punch and die), which can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a precision tool with a complex shape and bears the bulging force of the billet. It has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. The development level of mold production is one of the important symbols of the level of mechanical manufacturing; In addition to the mold itself, it also needs a mold base, a mold base, a guide device, and a part ejection device, etc., and these parts are generally made into a universal type.

Existing molds are generally connected to injection molding equipment through a panel. The setting of the panel greatly increases the use of materials, increases the cost of mold making, increases the difficulty of movement, prolongs the production cycle, and limits the improvement of production efficiency.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide an injection molding mold, which saves raw materials, saves mold manufacturing costs, shortens the production cycle, and improves production efficiency.

In order to achieve the above object, the utility model adopts the following technical solutions:

An injection molding mold, comprising a base plate, and a first plate body, a row pressing block, a second plate body, and a third plate body arranged sequentially on the base plate from top to bottom, and an thimble drag plate is arranged in the third plate body As well as the thimble plate provided on the thimble carriage, the first plate body has at least two mounting grooves on the two opposite sides, and each mounting hole is provided in the mounting groove, and the mounting holes are used for fixing with the injection molding equipment. For connection, a type hole is arranged on the top surface of the first plate body.

A first nozzle is vertically pierced through the bottom surface of the second board, and the first nozzle is inserted into the first board through the row pressing block, and a plurality of screw holes are also provided on the top surface of the first board.

A second nozzle is vertically pierced through the bottom surface of the ejector plate, and the second nozzle is fixed on the row position pressing plate through the second plate body.

The bottom surface of the third plate is closely attached to the bottom plate, one side of the bottom plate is connected to the corresponding side of the third plate through the first through screw, and the first through screw is connected to the second plate, and the other side of the bottom plate is connected by The second through screw is only connected to the corresponding side of the third board.

The thimble carriage is connected with the thimble board through screws, and the bottom surface of the thimble carriage is closely attached to the surface of the bottom plate.

The beneficial effect of the utility model is that: due to the installation structure design of the first plate body (that is, the installation groove with installation holes), the setting of the panel can be omitted, so that the overall mold becomes thinner. After the thinning, the first nozzle and The second nozzle sinks and shortens, which saves raw materials and mold manufacturing costs, making the mold lighter and easier to move than traditional molds, shortening the production cycle and improving production efficiency.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings of the description:

As shown in Figure 1-2, the utility model relates to an injection molding mold, including a bottom plate 1, and a first plate body 2, a row position pressing block 3, and a second plate body arranged on the bottom plate 1 sequentially from top to bottom. 4. The third plate body 5 , the ejector pin carriage 6 and the ejector pin plate 7 arranged on the ejector pin carriage 6 are arranged in the third plate body 5 .

As shown in Figure 1-2, the first plate body 2 is provided with at least two installation grooves 21 on the two opposite sides, and each installation groove 21 is provided with an installation hole 22, and the installation holes 22 are used for fixing with injection molding equipment. For connection, a hole 23 is provided on the top surface of the first plate body 2 .

As shown in Figure 1, the bottom surface of the second plate body 4 is vertically pierced with a first nozzle 8, and the first nozzle 8 is inserted in the first plate body 2 through the row position pressing block 3, and the first plate body 2 There are also several screw holes on the top surface, and each screw hole can be set according to the actual needs of connecting with the corresponding injection molding equipment, and there is no self-limitation here.

As shown in FIG. 1 , a second nozzle 9 is vertically pierced on the bottom surface of the ejector plate 7 , and the second nozzle 9 is fixed on the row position pressing plate through the second plate body 4 .

As shown in Figure 1, the bottom surface of the third plate body 5 is closely attached to the bottom plate 1, and the bottom plate 1 is connected to the corresponding side of the third plate body 5 through the first through screw a, and the first through screw a is connected to the second plate body. In the second plate body 4 , the other side of the bottom plate 1 is only connected to the corresponding side of the third plate body 5 through the second through screw b.

As shown in FIG. 1 , the thimble carriage 6 and the ejector plate 7 are connected by screws, and the bottom surface of the thimble carriage 6 is closely attached to the surface of the bottom plate 1 .

In the injection molding mold disclosed by the utility model, due to the installation structure design of the first plate body 2 (that is, the installation groove 21 with the installation hole 22), the setting of the panel is reduced, so that the overall thickness of the mold becomes thinner. The sinking and shortening of the first nozzle 8 and the second nozzle 9 saves raw materials and mold manufacturing costs, making the mold lighter and easier to move than traditional molds, shortening the production cycle and improving production efficiency.

The above is only a preferred embodiment of the utility model, not limiting the scope of the utility model, so under the premise of not departing from the design spirit of the utility model, ordinary engineers and technicians in the field can understand the structure described in the utility model, Equivalent changes or decorations made on features and principles should fall within the protection scope of the utility model patent application.
