Background

The mould is used for obtaining various moulds and tools of required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In particular, 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 injection mold, products with different structures are further injected by setting different shapes of the inner cavities. In the injection molding process, because the shapes of the structures are different, the structures of the pitched roof sliding block are sometimes needed to be used, so that the structures similar to the barbs (the local protrusions form the barb-shaped structures) are manufactured, but the manufacturing of the pitched roof sliding block can increase the volume of the mold, and the mold designs of different products are different.

Examples

Referring to fig. 1, 2, 3 and 4, the present embodiment provides a forming mold of a scanning gun, including a top mold 10 and a bottom mold 20, wherein the top mold 10 is provided with two mold core sliders 101 symmetrically arranged, a slide rail 1011 and a slider 1012 located on the slide rail 1011 are disposed on an end surface of one mold core slider 101 facing to the other mold core slider 101, and a slide shaft 1013 is disposed on the other mold core slider 101; the bottom die 20 is provided with a base die core 200 and an inclined guide pillar 201 connected with the die core slide block 101, the inclined guide pillar 201 is connected with the die core slide block 101 to form an inclined top slide block 1012 structure, an inner cavity formed by splicing the two die core slide blocks 101, the slide block 1012 and the base die core 200 is a die cavity 30, and the inclined guide pillar 201 is obliquely arranged towards the direction of the die cavity 30; when the two mold core slides 101 are separated, the slide axis 1013 drives the slide 1012 to slide on the slide 1011 in a direction away from the mold cavity 30.

The mold cavity 30 in this embodiment is the structure of the exterior housing of the scanning gun, thus forming the product of the scanning gun housing after injection molding is completed. Specifically, after the two mold core sliders 101 are spliced and the upper slider 1012 is combined, the splicing of the mold cavity 30 of the top mold 10 is realized; and then combined with the base mold core 200 of the bottom mold 20 to form a complete mold cavity 30. The forming mold of the scanning gun can be placed on the injection molding equipment for use, the purpose of automatic production is achieved, and the production efficiency is improved.

Specifically, when the top mold 10 and the bottom mold 20 are first closed, two mold core slides 101, one slide 1012 and one base mold core 200 are also engaged to form the mold cavity 30 by the closing action and the pulling force. At this time, the injection molding material is injected into the mold cavity 30 to complete the injection molding. After the injection molding material is cooled and solidified, the top mold 10 and the bottom mold 20 are separated, and the two mold core sliding blocks 101 are respectively driven by the two inclined guide pillars 201 to realize sliding separation in the way of inclined top sliding blocks 1012; meanwhile, the sliding shaft 1013 drives the sliding block 1012 to move and separate, so that the product is completely separated. The design of the inclined top sliding block 1012 with a smaller size and the design of the mould core sliding block 101 with a larger size are realized, and the sliding shaft 1013 drives the sliding block 1012 by utilizing the separation movement of the mould core sliding block 101, thereby effectively reducing the volume of a forming mould of a scanning gun and reducing the manufacturing cost.

As shown in fig. 3, the top surface of the top mold 10 in this embodiment is provided with an injection port 102 communicating with the mold cavity 30. By delivering or pouring the molding material (e.g., plastic) into the mold cavity 30 through the injection port 102, the top portion is designed to prevent spillage of the molding material in the mold cavity 30, thereby improving the safety and utility of injection molding.

The top surface of the top mold 10 in this embodiment is further provided with at least one air port (not shown) communicating with the mold cavity 30. Through the arrangement of the air ports, when the injection molding material is injected through the injection molding port 102, the air in the mold cavity 30 is discharged through the air ports, so that bubbles are prevented from being generated in the product, and the production quality is improved.

As shown in fig. 3, in the present embodiment, an ejector plate 202 and a stroke cavity 203 for accommodating the ejector plate 202 are disposed in the bottom mold 20, and at least one ejector pin penetrating through the mold cavity 30 is disposed on the ejector plate 202. When the top die 10 and the bottom die 20 are separated, the ejector plate 202 is driven to move, so that the product in the die cavity 30 is ejected, the product which is injected is conveniently taken, and the practicability is improved.

As shown in fig. 3, in the embodiment, at least one return spring 204 is disposed between the ejector plate 202 and the side of the stroke cavity 203 close to the mold cavity 30, and by the return spring 204, when the ejector plate 202 finishes ejecting the product, the ejector plate 202 can be returned to provide an initial force, so as to improve the smoothness of the movement and operation of the forming mold of the scanning gun.

As shown in fig. 2 and fig. 4, a first inclined hole is disposed between a first inclined post 201 and the bottom die 20, i.e. the diameter of the first inclined hole is slightly larger than that of the first inclined post 201; a second inclined hole 206 is arranged between the other inclined guide post 201 and the bottom die 20, and the diameter of the second inclined hole 206 is larger than that of the inclined guide post 201. Therefore, when the top mold 10 is separated from the bottom mold 20, the bottom mold 20 drives the slant guide pillar 201 to move through the first slant hole, so that the mold core slide 101 connected to the slant guide pillar 201 slides; the inclined guide post 201 in the second inclined hole 206 does not move (i.e. the difference between the diameter of the second inclined hole 206 and the diameter of the inclined guide post 201 does not move), so the other die core slide 101 is in a stationary state. At this time, the sliding shaft 1013 on the mold core slide 101 moves synchronously with the moving mold core slide 101, and then drives the slide 1012 to perform core pulling sliding, and completes the core pulling action of the slide 1012. Further, the top mold 10 and the bottom mold 20 are continuously separated until the second inclined hole 206 drives the other mold core slide block 101 to slide, so that the product is separated integrally, the ejector pins on the ejector pin plate 202 are convenient to eject the product, and the product is separated. And the action of gradually loosing core and separating the product can effectively reduce the probability of damage to the product during mold separation and improve the product production quality.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
