Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for molds, specifically a modification mold for the upper and lower parts of a machine body and casing. Background Technology

[0002] Mold Type: Molds for the machine body and casing are typically injection molds or die-casting molds. The design of these molds needs to consider factors such as material flowability, cooling systems, and draft angles. Material Selection: Based on the product's performance requirements, appropriate mold materials (such as steel, aluminum alloys, etc.) and injection molding materials (such as engineering plastics, metal alloys, etc.) are selected.

[0003] According to a public disclosure of a modification mold for the upper and lower parts of a machine body shell (publication number: CN211074509U), this utility model discloses a slider injection mold, which relates to the field of auxiliary devices for molds. It addresses the problem that existing slider injection molds often require manual operation when pushing the sliding rod, resulting in significant labor consumption. A stationary injection mold block is located at the middle of the upper end of the injection base plate. A moving injection mold block is located above the stationary block, and the stationary and moving blocks are connected by slots. Limit rod placement slots are provided at the four corners inside both the stationary and moving blocks. Limit rods are installed inside these slots and welded to the injection base plate. A sliding plate is located below the moving block, and is connected to it via slots. Two push base columns are located at the upper end of the sliding plate.

[0004] The aforementioned patent addresses the problem that existing slider injection molds often require manual operation when pushing the slider, which consumes a lot of labor. However, if the molding material remains at a high temperature before cooling, thermal expansion may cause the finished product to deform or shrink during demolding. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a modification mold for the upper and lower parts of the machine body and shell.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a body shell upper and lower modification mold, including a base, with a die-casting device and auxiliary devices arranged above the base; wherein, the die-casting device includes a base plate, a first fixing plate, a second fixing plate, a right mold, a fixing rod, a cooling plate, an electric push rod, a left mold, a first fixing button, a second fixing button, and a sliding rod; the base plate is fixedly installed on the top of the base, the first fixing plate is fixedly installed on the top of the base plate, the second fixing plate is fixedly installed on the top of the base plate, the right mold is fixedly installed on the left side of the first fixing plate, and the fixing rod is fixed... The cooling plate is slidably mounted on the circumferential surface of the fixing rod, and the fixed end of the electric push rod is fixedly mounted on the right side of the fixing plate. The left mold is fixedly mounted on the output end of the electric push rod. The first fixing button is fixedly mounted on the top of the left mold, and the second fixing button is fixedly mounted on the top of the cooling plate. The sliding rod is slidably mounted between the first fixing button and the second fixing button. The electric push rod pushes the left mold to drive the cooling plate to move continuously. The cooling plate eventually contacts the right mold. When the three are in contact, a mold cavity is formed. At this time, material is injected into the injection hole to complete the die casting.

[0007] As mentioned above, the right side of the fixing plate is provided with an injection hole for injecting material, and the top of the base plate is provided with a drop groove for the molded mold to fall through the drop groove.

[0008] The aforementioned auxiliary device includes a fixed plate three, a connecting rod, a mounting button, and a release agent tank. The fixed plate three is fixedly installed on the top of the base plate, the connecting rod is fixedly installed on the front side of the left mold, the mounting button is fixedly installed on the top of the connecting rod, and the release agent tank is fixedly installed on the top of the fixed plate three. The mounting button moves as the left mold moves, and the release agent tank replenishes the release agent into the hollow release agent block.

[0009] The aforementioned auxiliary device further includes a round rod, a hollow block, a piston block, and a nozzle ring. The round rod is fixedly installed on the right side of the mounting button, the hollow block is fixedly installed on the front side of the fixing plate three, the piston block is slidably installed on the inner wall of the hollow block, and the nozzle ring is fixedly installed on the front side of the hollow block. Through the contact between the round rod and the piston block, the piston block compresses the air inside the hollow block, causing the release agent to be output from the nozzle ring.

[0010] As described above, the release agent tank is connected to the hollow block via a pipe, the hollow block is connected to the nozzle ring, and a first spring is provided between the piston block and the hollow block, which drives the piston block to reset.

[0011] The auxiliary device described above also includes a collection box and a fixing block. The collection box is fixedly installed on the top of the base, and the fixing block is fixedly installed on the top of the base. A docking groove is provided on the left side of the collection box for installation.

[0012] The aforementioned auxiliary device further includes a limiting rod, a second spring, a hollow cylinder, a knob, and a brake block. The limiting rod slides through the inner and outer walls of the fixed block. The second spring is positioned between the fixed block and the limiting rod, and the limiting rod is reset by the second spring. The hollow cylinder is fixedly installed on the left side of the fixed block. The knob is rotatably installed on the circumferential surface of the hollow cylinder. The brake block is fixedly installed on the left side of the limiting rod. The right side of the limiting rod is set as an inclined surface. A spiral groove is provided on the circumferential surface of the hollow cylinder. The spiral groove is threadedly connected to the knob. By rotating the knob, the knob moves to the left upon contact with the spiral groove of the hollow cylinder.

[0013] Compared with existing technologies, this modified upper and lower body shell mold has the following advantages:

[0014] I. This utility model uses the output end of an electric push rod to move the left mold to the right, allowing the fixing button one, cooling plate, fixing button two, and right mold to come into contact and create a mold cavity. At this time, material is injected into the injection hole of fixing plate one, and the material enters the mold cavity through the injection hole to fill and form the mold. The cooling plate then rapidly cools and solidifies the mold. Through effective cooling, the time of each injection cycle is reduced, thereby improving production efficiency. Rapid cooling allows the mold to return to the next injection cycle more quickly, thus improving overall production capacity. After solidification, the output end of the electric push rod resets the left mold. At this time, the right side of the slide rod pulls the cooling plate to move until it is reset. The molded mold is then pushed out by the cooling plate and, after the output end of the electric push rod is fully reset, it falls out of the drop groove on the bottom plate.

[0015] II. This utility model utilizes the movement of the left mold in conjunction with a connecting rod, mounting button, round rod, piston block, mold release agent box, and hollow block to spray mold release agent from the nozzle ring. The sprayed mold release agent is then applied to the surface of the right mold, facilitating subsequent demolding. Using mold release agent can shorten cooling and demolding time, thereby improving production efficiency. This means that more injection molded parts can be produced in the same amount of time. The fallen molding material is collected in a collection box. By rotating the knob in conjunction with the hollow cylinder, spiral groove, brake block, limit rod, docking groove, and No. 2 spring, the collection box can be removed for mold processing. When installing the collection box, the outer wall of the collection box, in conjunction with the limit rod, No. 2 spring, and docking groove, completes the installation of the collection box, facilitating the processing of the molding material.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] 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 protection scope of the present utility model.

[0025] like Figure 1-6As shown, this utility model provides a technical solution: a body shell upper and lower modification mold, including a base 1, a die-casting device is arranged above the base 1, the die-casting device includes a base plate 10, a first fixing plate 11, a second fixing plate 12, a right mold 13, a fixing rod 14, a cooling plate 15, an electric push rod 151, a left mold 16, a first fixing button 17, a second fixing button 18 and a slide rod 19. The base plate 10 is fixedly installed on the top of the base 1, the first fixing plate 11 is fixedly installed on the top of the base plate 10, the second fixing plate 12 is fixedly installed on the top of the base plate 10, the right mold 13 is fixedly installed on the left side of the first fixing plate 11, and the fixing rod 14 is fixedly installed on the left side of the base plate 11. On the left side of the fixed plate 11, the cooling plate 15 is slidably mounted on the circumferential surface of the fixed rod 14. The fixed end of the electric push rod 151 is fixedly mounted on the right side of the fixed plate 12. The left mold 16 is fixedly mounted on the output end of the electric push rod 151. The first fixing button 17 is fixedly mounted on the top of the left mold 16. The second fixing button 18 is fixedly mounted on the top of the cooling plate 15. The slide rod 19 is slidably mounted between the first fixing button 17 and the second fixing button 18. Through effective cooling, the time of each injection cycle is reduced, thereby improving production efficiency. Rapid cooling allows the mold to return to the next injection cycle more quickly, thereby improving overall production capacity.

[0026] The right side of the fixing plate 11 is provided with an injection hole, and die casting is performed by injecting material into the injection hole. The top of the base plate 10 is provided with a drop groove.

[0027] The output end of the electric push rod 151 drives the left mold 16 to move to the right. The movement of the left mold 16 drives the first fixing button 17 to move until it contacts the cooling plate 15. At this time, the cooling plate 15 is continuously pushed by the left mold 16. The movement of the cooling plate 15 drives the second fixing button 18 to move until it contacts the right mold 13. At this time, the three contact each other to form a mold cavity. At this time, material is injected into the injection hole of the first fixing plate 11. The material enters the mold cavity through the injection hole and fills the mold. At this time, the cooling plate 15 quickly cools and solidifies the mold. After solidification, the output end of the electric push rod 151 resets the left mold 16. At this time, the right side of the slide rod 19 pulls the cooling plate 15 to move until it is reset. The molded mold is pushed out by the cooling plate 15 and falls out of the drop groove of the bottom plate 10 after the output end of the electric push rod 151 is completely reset.

[0028] The auxiliary device includes a fixing plate 20, a connecting rod 21, a mounting button 22, and a mold release agent tank 221. The fixing plate 20 is fixedly installed on the top of the base plate 10, the connecting rod 21 is fixedly installed on the front side of the left mold 16, the mounting button 22 is fixedly installed on the top of the connecting rod 21, and the mold release agent tank 221 is fixedly installed on the top of the fixing plate 20. Mold release agent is injected into the hollow block 24 through the mold release agent tank 221.

[0029] The auxiliary device also includes a round rod 23, a hollow block 24, a piston block 25, and a nozzle ring 26. The round rod 23 is fixedly installed on the right side of the mounting button 22, the hollow block 24 is fixedly installed on the front side of the fixing plate 20, the piston block 25 is slidably installed on the inner wall of the hollow block 24, and the nozzle ring 26 is fixedly installed on the front side of the hollow block 24 to facilitate subsequent demolding. Using a release agent can shorten the cooling and demolding time, thereby improving production efficiency. This means that more injection molded parts can be produced in the same amount of time.

[0030] The mold release agent tank 221 is connected to the hollow block 24 through a pipe. The hollow block 24 is connected to the nozzle ring 26. A first spring is provided between the piston block 25 and the hollow block 24. The piston block 25 is reset by the first spring.

[0031] The auxiliary device also includes a collection box 27 and a fixing block 28. The collection box 27 is fixedly installed on the top of the base 1, and the fixing block 28 is fixedly installed on the top of the base 1. A docking groove is provided on the left side of the collection box 27, and the fallen molding material is collected through the collection box 27.

[0032] The auxiliary device also includes a limiting rod 29, a second spring 210, a hollow cylinder 211, a knob 212, and a brake block 213. The limiting rod 29 slides through the inner and outer walls of the fixed block 28. The second spring 210 is located between the fixed block 28 and the limiting rod 29. The hollow cylinder 211 is fixedly installed on the left side of the fixed block 28. The knob 212 is rotatably installed on the circumferential surface of the hollow cylinder 211. The brake block 213 is fixedly installed on the left side of the limiting rod 29. The right side of the limiting rod 29 is set as an inclined surface. The circumferential surface of the hollow cylinder 211 is provided with a spiral groove, which is threadedly connected to the knob 212. The quick installation and disassembly of the collection box 27 facilitates the processing of the formed material.

[0033] The movement of the left mold 16 moves the connecting rod 21, which in turn moves the mounting button 22, which in turn moves the round rod 23. The round rod 23 then contacts the piston block 25, injecting mold release agent into the hollow block 24 through the mold release agent tank 221. The movement of the piston block 25 compresses the air inside the hollow block 24, causing the mold release agent to be sprayed out through the nozzle ring 26. The sprayed mold release agent is then applied to the surface of the right mold 13, facilitating subsequent demolding. The fallen molding material is collected in the collection box 27. Rotating the knob 212, which contacts the spiral groove of the hollow cylinder 211, moves the knob 212 to the left. When the knob 212 moves, it will contact the brake block 213. After the brake block 213 is contacted, it will move to the left. The movement of the brake block 213 will drive the limit rod 29 to move. The movement of the limit rod 29 will disengage from the docking groove of the collection box 27 and compress the second spring 210. At this time, the collection box 27 can be removed to process the mold. When installing the collection box 27, the outer wall of the collection box 27 will contact the inclined surface of the limit rod 29, causing the limit rod 29 to move to the left and compress the second spring 210. When the limit rod 29 and the docking groove are on the same horizontal plane, the second spring 210 is released and drives the limit rod 29 to insert into the docking groove. At this time, the installation of the collection box 27 is completed.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
