Description

Technical Field

[0001] This utility model relates to the field of injection mold assembly, specifically an injection mold that is easy to assemble. Background Technology

[0002] Injection molds can be used to produce different products by changing the shape of the mold. The process involves injecting plastic material that has been completely melted by a screw at a certain temperature into the mold cavity under high pressure. After cooling and solidification, the product is obtained. This method is suitable for the mass production of complex-shaped parts and is one of the important processing methods. With the continuous development of modern society, injection molds have also been continuously developed and innovated, and now basically meet people's needs.

[0003] However, most traditional injection molds have simple structures and lack limiting structures. Without a limiting structure, operators need to manually align the mold core, mold frame, and other components, relying on visual inspection or measuring tools, which increases assembly time. In mass production, frequent adjustments increase labor costs and can easily lead to operational errors due to fatigue. Furthermore, when the limiting structure is fixed, slight displacement may occur after the moving mold and fixed mold close, resulting in flash, burrs, or dimensional deviations in the product. Under high-temperature environments, plastic shrinkage or mold expansion may further amplify the deviations, affecting product consistency. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, most traditional injection molds have simple structures and lack limiting structures. Without limiting structures, operators need to manually align components such as mold cores and mold frames, relying on visual inspection or measuring tools, which leads to increased assembly time and other problems. This utility model proposes an injection mold that is easy to assemble.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an injection mold that is easy to assemble, including a base plate, a sliding groove is provided on one side of the base plate, the number of the sliding grooves is four, and a limiting structure is provided in the inner cavity of the base plate;

[0006] The limiting structure includes four slide rails. One side of each of the four slide rails is fixedly connected to the inner wall of the base plate. A rack is slidably connected to the surface of each slide rail. An extension block is fixedly connected to one side of each rack. The surface of each extension block is slidably connected to the inner wall of a corresponding slide groove. A limiting clamp is fixedly connected to one end of each extension block. One side of the limiting clamp is attached to one side of the base plate.

[0007] Preferably, the inner cavity of the base plate is rotatably connected to a gear, and the teeth of the gear mesh with the teeth of the rack.

[0008] Preferably, the base plate has four fixing holes on one side, and each of the four fixing holes is threaded with a first fixing bolt, one end of which abuts against one side of the corresponding extension block.

[0009] Preferably, a partition plate is provided on one side of the base plate, a support plate is provided on one side of the partition plate, a template is provided on one side of the support plate, a top plate is provided on one side of the template, and one side of the limiting clamp is attached to the partition plate, the support plate and the template.

[0010] Preferably, a fixing groove is provided on one side of the limiting clamp, and a second fixing bolt is inserted into the inner wall of the fixing groove. The surface of the second fixing bolt is threadedly connected to the inner cavity of the template.

[0011] Preferably, a gasket is fitted on the surface of the second fixing bolt, one side of which is attached to one side of the limiting clamp, and a reinforcing cap is threaded onto the surface of the second fixing bolt, one side of which is attached to one side of the gasket.

[0012] Preferably, a reinforcing plate is provided on one side of the bearing plate and the template, and a third fixing bolt is inserted into the inner cavity of the reinforcing plate. There are two third fixing bolts, and the surfaces of the two third fixing bolts are threadedly connected to the inner cavities of the bearing plate and the template, respectively.

[0013] The advantages of this utility model are:

[0014] This invention uses a limiting structure to restrict the assembly positions of the partition plate, support plate, template, and stripper plate, improving the ease of injection mold assembly. The limiting clamps on the four sides of the partition plate, support plate, template, and stripper plate are all fixedly connected to the corresponding racks via extension blocks. The four sets of racks are staggered in height, and the cooperation of the racks and gears connects the four sets of limiting clamps into a single unit. According to the width of the partition plate, support plate, template, and stripper plate, one set of limiting clamps is pushed, and the limiting clamps can drive the racks to slide along the surface of the slide rail. While one set of racks drives the gear to rotate, it can drive the other three racks to slide synchronously, thereby synchronously adjusting the spacing of the four sets of limiting clamps. This allows for the restriction and clamping of partition plates, support plates, templates, and stripper plates of different widths. This solves the problems of most traditional injection molds having simple structures and lacking limiting structures. Without a limiting structure, operators need to manually align the mold core, mold frame, and other components, relying on visual inspection or measuring tools, which increases assembly time.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an injection mold that is easy to assemble. (Refer to...) Figures 1 to 3 An easy-to-assemble injection mold includes a base plate 1, a groove 2 is provided on one side of the base plate 1, the number of grooves 2 is four, and a limit structure 3 is provided in the inner cavity of the base plate 1.

[0025] The limiting structure 3 includes four slide rails 301. One side of each of the four slide rails 301 is fixedly connected to the inner wall of the base plate 1. Each slide rail 301 has a rack 302 slidably connected to its surface. One side of each rack 302 has an extension block 303 fixedly connected to its side. The surfaces of the extension blocks 303 are slidably connected to the inner walls of their respective slide grooves 2. One end of each extension block 303 is fixedly connected to a limiting clamp 304. One side of the limiting clamp 304 is attached to one side of the base plate 1. A gear 305 is rotatably connected to the inner cavity of the base plate 1. The teeth of the gear 305 mesh with the teeth of the rack 302. One side of the base plate 1 has a partition plate 6. One side of the partition plate 6 has a support plate 7. One side of the support plate 7 has a template 8. One side of the template 8 has a top plate 9. One side of the limiting clamp 304 is attached to one side of the partition plate 6, the support plate 7, and the template 8.

[0026] The base plate 1 in this easily assembled injection mold plays a major supporting role. The base plate 1, partition plate 6, support plate 7, template 8, and top plate 9 combine to form the existing injection mold. The limiting structure 3 can limit the assembly position of the partition plate 6, support plate 7, and template 8, improving the ease of injection mold assembly. The limiting clamps 304 on all four sides of the partition plate 6, support plate 7, and template 8 are all fixedly connected to the corresponding racks 302 via extension blocks 303. The four sets of racks 302 are arranged with staggered heights. The gear 305 and the four sets of limiting clamps 304 are connected into one unit. According to the width of the partition plate 6, the support plate 7 and the template 8, one set of limiting clamps 304 is pushed. The limiting clamps 304 can drive the rack 302 to slide along the surface of the slide rail 301. While the rack 302 drives the gear 305 to rotate, it can drive the other three racks 302 to slide synchronously, thereby synchronously adjusting the spacing of the four sets of limiting clamps 304 so as to limit and clamp the partition plate 6, the support plate 7 and the template 8 of different widths.

[0027] Reference Figure 2 The base plate 1 has four fixing holes 4 on one side. Each fixing hole 4 is threaded with a first fixing bolt 5. One end of the first fixing bolt 5 abuts against one side of the corresponding extension block 303. When the limiting clamp 304 is attached to the partition plate 6, the first fixing bolt 5 abuts against one side of the extension block 303, thereby pushing the extension block 303 and the limiting clamp 304 to fit tightly against one side of the partition plate 6, the support plate 7 and the template 8, and minimizing the rotation of the gear 305.

[0028] Reference Figure 1 and Figure 4A fixing groove 306 is provided on one side of the limiting clamp 304. A second fixing bolt 10 is inserted into the inner wall of the fixing groove 306. The surface of the second fixing bolt 10 is threadedly connected to the inner cavity of the template 8. Through the second fixing bolt 10, the second fixing bolt 10 passes through the fixing groove 306 and is fixedly connected to the template 8 to form a whole, thereby strengthening the connection between the limiting clamp 304 and the injection mold.

[0029] Reference Figure 4 A gasket 11 is fitted on the surface of the second fixing bolt 10. One side of the gasket 11 is attached to one side of the limiting clamp 304. A reinforcing cap 12 is threaded onto the surface of the second fixing bolt 10. One side of the reinforcing cap 12 is attached to one side of the gasket 11. By continuously twisting the reinforcing cap 12 along the surface of the second fixing bolt 10, the reinforcing cap 12 pushes the gasket 11 to fit tightly against the limiting clamp 304, further improving the stability of the limiting clamp 304.

[0030] Reference Figure 1 and Figure 5 A reinforcing plate 13 is provided on one side of the bearing plate 7 and the template 8. A third fixing bolt 14 is inserted into the inner cavity of the reinforcing plate 13. There are two third fixing bolts 14. The surfaces of the two third fixing bolts 14 are threadedly connected to the inner cavities of the bearing plate 7 and the template 8, respectively. Through the reinforcing plate 13, the third fixing bolts 14 pass through the reinforcing plate 13 and are threadedly connected to the inner cavities of the bearing plate 7 and the template 8, thereby further improving the strength of the injection mold.

[0031] Working Principle: The base plate 1 provides the main support. The base plate 1, partition plate 6, support plate 7, template 8, and top plate 9 combine to form the existing injection mold. The limiting structure 3 restricts the assembly position of the partition plate 6, support plate 7, and template 8, improving the ease of mold assembly. The limiting clamps 304 on all four sides of the partition plate 6, support plate 7, and template 8 are fixedly connected to the corresponding racks 302 via extension blocks 303. The four sets of racks 302 are staggered in height. The cooperation of the racks 302 and gears 305 connects the four sets of limiting clamps 304 into a single unit. A set of limiting clamps 304 is pushed according to the width of the partition plate 6, support plate 7, and template 8. The limiting clamps 304 can drive the racks 302 to slide along the surface of the slide rail 301. While one set of racks 302 drives the gears 305 to rotate, it can simultaneously drive the other three racks 302 to slide synchronously. Adjust the spacing of the four sets of limiting clamps 304 to limit and clamp the partition plates 6, bearing plates 7 and templates 8 of different widths. When the limiting clamps 304 are attached to the partition plates 6, one end of the first fixing bolt 5 abuts against one side of the extension block 303, thereby pushing the extension block 303 and the limiting clamps 304 to fit tightly against one side of the partition plates 6, bearing plates 7 and templates 8, and avoiding the gears 305 from rotating as much as possible. The second fixing bolt 10 passes through the fixing groove 306 and is fixedly connected to the template 8 as one piece, thereby strengthening the connection between the limiting clamps 304 and the injection mold. Continuously screw the reinforcing cap 12 along the surface of the second fixing bolt 10. The reinforcing cap 12 pushes the washer 11 to fit tightly against the limiting clamps 304, further improving the stability of the limiting clamps 304. The third fixing bolt 14 passes through the reinforcing plate 13 and is threadedly connected to the inner cavity of the bearing plate 7, further improving the strength of the injection mold.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
