Technical Field

[0001] The utility model relates to the technical field of thin-wall molds, in particular to a thin-wall mold with uniform glue flow. Background Art

[0002] Thin-wall molds with uniform glue flow are an advanced mold technology. By optimizing the flow path of the plastic material and the design of the cooling system, it ensures that the molten plastic can be evenly distributed when flowing through the mold, thereby producing higher quality and thinner-walled plastic products. This type of mold is usually made using high-precision CNC machining technology and has excellent dimensional accuracy and surface finish. During the design process, engineers will use mold flow analysis software to simulate the plastic filling process to determine the optimal gate location, number and size, as well as the layout of the runner system, which can minimize the pressure loss and temperature difference of the molten plastic during the filling process.

[0003] According to the search, the Chinese patent document, announcement number: CN209141260U, discloses that the utility model discloses a thin-walled mold with uniform glue flow, including an upper fixed plate, a lower fixed plate and an airway gap, the lower end surface of the heating plate is connected with two groups of hot nozzles, and a stripper plate is arranged under the hot nozzle, an upper mold core is arranged under the stripper plate, and a lower mold core is arranged below the upper mold core, a pad is arranged at the lower periphery of the lower mold core, a vent pipe 1 is installed at the center of the lower mold core, and a ejector plate is arranged at the lower end of the vent pipe 1, a product is pressed between the upper mold core and the lower mold core, and airway gaps are arranged on the inner and outer sides of the product. The thin-walled mold with uniform glue flow has airways for air intake and exhaust in the mold cavity, and the exhaust is good during product molding, the molding time is short for uniform glue flow, and the scrap rate is low. Air blowing when the product is ejected can eliminate the vacuum adsorption problem between the product and the mold, and the product is easy to take out.

In view of this, we provide a thin-walled mold with uniform glue flow. Utility Model Content

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a thin-walled mold with uniform glue flow.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thin-walled mold with uniform glue flow, including a bottom mold, a top mold is slidably connected to the center of the top of the bottom mold, and a top plate is slidably connected to the center of the top of the top mold, a plurality of sliding shafts are respectively fixedly connected to the two sides of the bottom surface of the top plate, and a foot seat is fixedly connected to the bottom surface of the sliding shaft, the bottom end of the outer wall of the sliding shaft penetrates and is fixedly connected to the inner side of the bottom mold, and the center of the outer wall of the sliding shaft penetrates the inner side of the top mold and is slidably connected thereto, a sealing groove is opened at the center of the top surface of the bottom mold, and a glue injection groove is also opened at the center of the top surface of the bottom mold, a sealing strip is fixedly connected to the center of the bottom surface of the top mold, and observation holes are respectively opened on both sides of the top surface of the top mold, and a glue pushing plate is slidably connected to the bottom end of the glue injection groove.

[0009] As mentioned above, a threaded sleeve is fixedly connected at the center of the top surface of the top mold, and the inner wall of the threaded sleeve is provided with threads. The bottom end of the outer wall of the threaded shaft penetrates the inner center of the threaded sleeve through threads and is rotatably connected to the threaded sleeve.

[0010] As mentioned above, the bottom mold is fixedly connected to a bottom plate at the inner center, and guide blocks are fixedly connected to both sides of the top surface of the bottom plate. A slider is penetrated and slidably connected to the bottom end of the outer wall of the guide block, and the outer wall at the top end of the slider is fixedly connected to one side of the bottom surface of the rubber push plate.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 As shown, the utility model provides a technical solution for a thin-walled mold with uniform glue flow: a thin-walled mold with uniform glue flow, comprising a bottom mold 1, a top mold 101 is slidably connected to the center of the top of the bottom mold 1, and a top plate 2 is slidably connected to the center of the top of the top mold 101, a plurality of sliding shafts 201 are respectively fixedly connected to both sides of the bottom surface of the top plate 2, and a foot seat 202 is fixedly connected to the bottom surface of the sliding shaft 201, the bottom end of the outer wall of the sliding shaft 201 penetrates and is fixedly connected to one side of the inside of the bottom mold 1, and the center of the outer wall of the sliding shaft 201 penetrates one side of the inside of the top mold 101 and is slidably connected thereto, a sealing groove 102 is opened at the center of the top surface of the bottom mold 1, and a glue injection groove 103 is also opened at the center of the top surface of the bottom mold 1, a sealing strip 104 is fixedly connected to the center of the bottom surface of the top mold 101, and observation holes 105 are respectively opened on both sides of the top surface of the top mold 101, and a glue pushing plate 3 is slidably connected to the bottom end of the glue injection groove 103.

[0026] Since the sliding shaft 201 penetrates the inner edge of the top mold 101, the top mold 101 is limited. By driving the pressing plate motor 204, the threaded shaft 203 rotates through the outer wall thread, and the threaded sleeve 205 and the top mold 101 are vertically moved along the sliding shaft 201 to the top surface of the bottom mold 1. When the sealing strip 104 and the sealing groove 102 fit each other, glue is injected between the bottom mold 1 and the top mold 101. The operator can observe the glue injection through the observation hole 105. When the observation holes 105 on both sides of the top surface of the top mold 101 have glue overflowing, the glue injection is successful. After the colloid is formed, the lifting cylinder 3 is driven to 05. Since the rubber pushing plate 3 is limited by the sliders 303 and the guide blocks 302 on both sides of the bottom surface, it can only move vertically up and down on the top of the bottom plate 301. When the telescopic end of the lifting cylinder 305 extends outward, it drives the lifting column 306 to move away from the lifting cylinder 305. The lifting column 306 pushes the lifting frame 307 and the rubber pushing plate 3 into the glue injection groove 103 through the lifting inclined groove 308, and successfully demolds the colloid, so that the device can quickly and effectively demold the colloid, and effectively avoids the deformation of the colloid surface or the inability to demold due to uneven force on the colloid surface.

[0027] like Figure 1-4 As shown, a threaded shaft 203 is rotatably connected to the inner center of the top plate 2, and a pressure plate motor 204 is fixedly connected to the center of the top surface of the top plate 2. The top end of the outer wall of the threaded shaft 203 passes through the center of the bottom surface of the top plate 2 and is fixedly connected to the output end of the pressure plate motor 204. A threaded sleeve 205 is fixedly connected to the center of the top surface of the top mold 101, and the inner wall of the threaded sleeve 205 is provided with a thread. The bottom end of the outer wall of the threaded shaft 203 passes through the inner center of the threaded sleeve 205 through a thread and is rotatably connected to the threaded sleeve 205.

[0028] Since the sliding shaft 201 passes through the inner edge of the top mold 101, the top mold 101 is limited. By driving the pressure plate motor 204, the threaded shaft 203 rotates through the outer wall thread to vertically move the threaded sleeve 205 and the top mold 101 toward the top surface of the bottom mold 1 along the sliding shaft 201. When the sealing strip 104 and the sealing groove 102 fit each other, glue is injected between the bottom mold 1 and the top mold 101. The operator can observe the glue injection through the observation hole 105. When glue overflows from the observation holes 105 on both sides of the top surface of the top mold 101, the glue injection is successful, so that the device can manually observe the glue injection uniformity through the observation hole 105, thereby achieving uniform glue injection in the mold.

[0029] like Figure 3 , Figure 5 and Figure 6As shown, a bottom plate 301 is fixedly connected to the inner center of the bottom mold 1, and guide blocks 302 are fixedly connected to both sides of the top surface of the bottom plate 301, a slider 303 is penetrated and slidably connected to the bottom end of the outer wall of the guide block 302, and the outer wall of the top end of the slider 303 is fixedly connected to one side of the bottom surface of the rubber pushing plate 3, a cylinder frame 304 is fixedly connected to one side of the bottom surface of the bottom plate 301, and a lifting cylinder 305 is fixedly connected to the outer wall of one side of the cylinder frame 304, a group of corresponding lifting columns 306 are fixedly connected to both sides of the output end of the lifting cylinder 305, a lifting frame 307 is fixedly connected to the center of the bottom surface of the rubber pushing plate 3, and lifting inclined grooves 308 are respectively opened on both sides of the outer wall of the lifting frame 307, one end of the outer wall of the lifting column 306 penetrates the top of the inner wall of the lifting inclined groove 308, and one end of the outer wall of the lifting column 306 is slidably connected to one end of the inner wall of the lifting inclined groove 308.

[0030] After the colloid is formed, the lifting cylinder 305 is driven. Since the rubber pushing plate 3 is limited by the sliders 303 and the guide blocks 302 on both sides of the bottom surface, it can only move vertically up and down on the top of the bottom plate 301. When the telescopic end of the lifting cylinder 305 extends outward, it drives the lifting column 306 to move away from the lifting cylinder 305. The lifting column 306 pushes the lifting frame 307 and the rubber pushing plate 3 into the glue injection groove 103 through the lifting inclined groove 308, and successfully demolds the colloid, so that the device can quickly and effectively demold the colloid, and effectively avoids the deformation of the colloid surface or the inability to demold due to uneven force on the colloid surface.

[0031] Working principle: Since the sliding shaft 201 penetrates the inner edge of the top mold 101, the top mold 101 is limited. By driving the pressure plate motor 204, the threaded shaft 203 rotates through the outer wall thread, and the threaded sleeve 205 and the top mold 101 are vertically moved along the sliding shaft 201 to the top surface of the bottom mold 1. When the sealing strip 104 and the sealing groove 102 fit each other, the glue is injected between the bottom mold 1 and the top mold 101. The operator can observe the glue injection situation through the observation hole 105. When the observation holes on both sides of the top surface of the top mold 101 are When glue overflows from 105, the glue injection is successful. After the colloid is formed, the lifting cylinder 305 is driven. Since the glue pushing plate 3 is limited by the sliders 303 and the guide blocks 302 on both sides of the bottom surface, it can only move vertically up and down on the top of the bottom plate 301. When the telescopic end of the lifting cylinder 305 extends outward, it drives the lifting column 306 to move away from the lifting cylinder 305. The lifting column 306 pushes the lifting frame 307 and the glue pushing plate 3 into the glue injection groove 103 through the lifting inclined groove 308, and successfully demolds the colloid.
