Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and particularly to a synchronous laminated injection mold. Background Art

[0002] According to statistics, about 90% of automotive interior and exterior parts and 70% of home appliance parts are molded by injection molds. Therefore, the injection production efficiency of the molds will directly affect the delivery date of the products.

[0003] Currently, traditional injection molds mostly adopt the cooperation of a single fixed mold and a moving mold, and can only process single-layer injection parts. In this mode, the production rate of the injection parts is limited and it is difficult to meet the large-scale production requirements. At the same time, it is difficult to demold the molded injection parts. Manual demolding is not only time-consuming and laborious, but also further reduces the overall working efficiency of the injection mold. Secondly, the existing injection molds have deficiencies in the heat dissipation design in the cavity, resulting in uneven cooling of the injection parts. This not only prolongs the cooling time and the molding cycle, affects the part picking efficiency, but also may affect the quality and performance of the injection parts due to local overheating.

This synchronous laminated injection mold, through the set cooling system components, first the cooling channel one can transfer the coolant to the inside of the first cavity and the second cavity respectively, thus quickly completing the synchronous cooling of the first cavity and the second cavity, which first improves the cooling efficiency of the injection molded parts. Then the cooling channel two can transfer the coolant to the inside of the fixed mold plate and the moving mold plate respectively, thus quickly completing the synchronous cooling of the fixed mold plate and the moving mold plate, which improves the cooling efficiency of the injection molded parts again.

Then, when the second hydraulic cylinder is controlled to start, it can drive the right push rod to move to the left. When the right push rod moves to the left, it can drive the second push plate and the second push rod fixing plate to move to the left simultaneously. When the second push rod fixing plate moves to the left, it can drive the first right demolding rod and the second right demolding rod to move to the left simultaneously. When the first right demolding rod moves to the left, it can quickly complete the demolding of the molded parts in the other layer, and when the second right demolding rod moves to the left, it can quickly complete the demolding of the right-side waste. Through the coordinated use of the first hydraulic cylinder and the second hydraulic cylinder, the demolding of the double-layer molded parts can be quickly completed, thus greatly improving the production efficiency of the injection mold.

The movable template 6, the two second pads 7, and the movable mold base plate 8 are connected to each other. A synchronous valve needle hot runner mechanism 9 is arranged inside the first cavity 4 and the second cavity 5. Cooling system components 10 are arranged inside the fixed template 3, the first cavity 4, the second cavity 5, and the movable template 6. Synchronous mold opening mechanisms 11 are arranged on the front and back surfaces of the fixed template 3, the first cavity 4, the second cavity 5, and the movable template 6.

[0061] The synchronous mold opening mechanism 11 includes two first track grooves 1101, two second track grooves 1102, two mold opening racks 1103, a stabilizing cross column 1104, four limit card seats 1105, two demolding gears 1106, and two protective covers 1107. Lubrication components 12 are installed on the surfaces of the two protective covers 1107. Step-by-step demolding components 13 are arranged inside the fixed template 3 and the movable template 6.

[0062] The synchronous valve needle hot runner mechanism 9 includes: a hot runner plate 901, which is fixed inside the first cavity 4 and the second cavity 5 by multiple groups of bolts; valve type main nozzles 902 are embedded in the middle positions of both side surfaces of the hot runner plate 901. The left end of the valve type main nozzle 902 penetrates the left side surface of the first cavity 4 and extends to the outside. Two first runner nozzles 903 are embedded in the left side surface of the lower end of the hot runner plate 901.

[0063] The cooling system component 10 includes: a first cooling channel 1001 respectively opened on the lower surfaces of the fixed mold plate 3 and the moving mold plate 6; a second cooling channel 1002 respectively opened on the lower surfaces of the first cavity 4 and the second cavity 5.

[0064] Among them, through the set cooling system component 10, the coolant is first respectively transported into the interiors of the first cooling channel 1001 and the second cooling channel 1002. At this time, the first cooling channel 1001 can respectively transport the coolant into the interiors of the first cavity 4 and the second cavity 5, thereby quickly completing the synchronous cooling of the first cavity 4 and the second cavity 5, thus improving the cooling efficiency of the injection molded part first. Then, the second cooling channel 1002 can respectively transport the coolant into the interiors of the fixed mold plate 3 and the moving mold plate 6, thereby quickly completing the synchronous cooling of the fixed mold plate 3 and the moving mold plate 6, thus improving the cooling efficiency of the injection molded part again. Through the cooperation of the first cooling channel 1001 and the second cooling channel 1002, the synchronous cooling of both sides of the injection molded part can be quickly achieved, and this efficient cooling system can significantly shorten the cooling time of the injection molded part.

[0065] The lubrication assembly 12 includes: two groups of infusion tubes 1201, with four infusion tubes 1201 in each group, and the ends of the two groups of infusion tubes 1201 close to each other are respectively embedded in the surfaces of two protective covers 1107; a counterpoint oil hole 1202 is opened on the surface of each infusion tube 1201 close to the parting gear 1106, and a plurality of flow dividing columns are arranged on the inner wall of the counterpoint oil hole 1202; one transfer tube 1203 is connected to the end of each infusion tube 1201 far from the protective cover 1107, a return spring 1204 is fixedly connected to the inner wall of each transfer tube 1203 close to the protective cover 1107, an inner follower ring plate 1205 is fixedly connected to the end of each return spring 1204 far from the protective cover 1107, and a horizontal strut 1206 fixedly connected to the inner wall of the infusion tube 1201 is arranged inside each return spring 1204; an oil injection cylinder 1207 is fixedly installed on the surface of the end of each infusion tube 1201 far from the protective cover 1107, an inner push plug 1208 is fixedly connected to the output end of each oil injection cylinder 1207, a liquid storage barrel 1209 is installed on the top of each oil injection cylinder 1207, a main delivery pipe 1210 is connected between each liquid storage barrel 1209 and each transfer tube 1203, two inner stirring plates 1211 are arranged on the inner wall of each liquid storage barrel 1209, and two CCD cameras 1212 are respectively embedded on the opposite sides of the two protective covers 1107.

[0066] Among them, through the lubrication component 12 provided, first, when the CCD camera 1212 is controlled to turn on, the corrosion degree and damage degree between the mold-opening rack 1103 and the mold-splitting gear 1106 can be observed in real time. When rust appears or there is a lack of oil at the connection between the gear and the rack, the main delivery pipe 1210 can quantitatively transfer the lubricating oil in the liquid storage barrel 1209 to the inside of the transfer pipe 1203. At this time, controlling the oil delivery cylinder 1207 to start can drive the inner push plug 1208 to push the lubricating oil. When the inner follower ring plate 1205 disengages from the closure of the infusion pipe 1201, the infusion pipe 1201 can then transfer the lubricating oil in multiple directions to the connection between the mold-opening rack 1103 and the mold-splitting gear 1106, so as to ensure that the lubricating oil can be evenly transferred to the surface of the moving mold-opening structure. And by precisely controlling the transfer amount of the lubricating oil, it is ensured that the surfaces of the rack and the gear are always in the best lubrication state. After the delivery is completed, controlling the oil delivery cylinder 1207 to start again, the oil delivery cylinder 1207 starting can drive the inner push plug 1208 back to the initial position. At this time, the elastic force of the return spring 1204 will push the inner follower ring plate 1205 back to the initial position. At this time, the inner follower ring plate 1205 can close the infusion pipe 1201 again and ensure that the space between the inner follower ring plate 1205 and the inner push plug 1208 is a quantitative space. At this time, the main delivery pipe 1210 can transfer the lubricating oil in the liquid storage barrel 1209 to the inside of the transfer pipe 1203 quantitatively again, and promote the continuous use of the lubrication component 12, greatly improving the practicability of the injection mold.

[0067] Among them, through the inner stirring plate 1211 provided, first, the liquid storage barrel 1209 will shake left and right along with the movement of the synchronous mold-opening mechanism 11, and then the inner stirring plate 1211 can automatically stir the lubricating oil shaking inside the liquid storage barrel 1209, thereby preventing the lubricating oil from precipitating and improving the utilization rate of the lubricating oil.

Two groups of second left demolding rods 1306 are fixedly connected to the upper right side surface of the first push rod fixing plate 1303, and the right ends of the two groups of second left demolding rods 1306 penetrate through the right side surface of the fixed template 3; a second push plate 1307 is sleeved on the surface of the right end of the right inner fixing column 1301, a second push rod fixing plate 1308 is fixedly installed on the left side surface of the second push plate 1307, a right push rod 1309 is embedded in the middle position of the right side surface of the second push plate 1307, a second hydraulic cylinder 1310 is fixedly installed on the lower right side surface of the moving mold base plate 8, and the output end of the second hydraulic cylinder 1310 is fixedly connected to the right end of the right push rod 1309. Two groups of first right demolding rods 1311 are fixedly connected to the left side surface of the second push rod fixing plate 1308, and the left ends of the two groups of first right demolding rods 1311 extend into the mold cavity on the left side of the moving template 6 respectively. Two groups of second right demolding rods 1312 are fixedly connected to the upper left side surface of the second push rod fixing plate 1308, and the left ends of the two groups of second right demolding rods 1312 penetrate through the left side surface of the moving template 6 respectively.

[0070] During operation, first, the driving component is used to push the moving mold base plate 8 to the left. When the moving mold base plate 8 moves to the left, the synchronous mold opening mechanism 11 will control the first cavity 4 and the fixed mold plate 3, and the second cavity 5 and the moving mold plate 6 to be synchronously closed. Then, it will control the external injection nozzle to dock with the valve-type main nozzle 902 and convey the injection plastic. At this time, opening the control valve-type main nozzle 902 can transfer the input injection material to the inside of the first runner nozzle 903 and the second runner nozzle 904 respectively through the shunt channel. Then, controlling the first runner nozzle 903 and the second runner nozzle 904 to open respectively can transfer the injection material to the multiple cavities of the first cavity 4 and the second cavity 5 through the first injection hole 906 and the second injection hole 908 respectively, realizing efficient double-layer cavity injection molding. Then, heating wires are arranged on the surfaces of the first runner nozzle 903 and the second runner nozzle 904. By energizing the heating wires, the synchronous heating of multiple nozzles can be quickly completed, so that the injection material can be effectively guaranteed to be in a molten state continuously. When the injection of the injection plastic in the two side cavities is completed, the valve-type main nozzle 902, the first runner nozzle 903 and the second runner nozzle 904 are closed simultaneously, and then the injection molding work is quickly completed;

[0071] Among them: Compared with the traditional single-layer injection mold, the production efficiency of this synchronous laminated injection mold is increased by 200% under the same machine (the first cavity 4 and the fixed mold plate 3, and the second cavity 5 and the moving mold plate 6 constitute synchronous molding of a double cavity);

[0072] Compared with the traditional single-layer injection mold, the cooling time of this synchronous laminated injection mold is shortened by 25% (cooling liquid passes through the inside of the first cavity 4 and the fixed mold plate 3, and the second cavity 5 and the moving mold plate 6, so as to form a double-sided cooling system);

[0073] Compared with the traditional single-layer injection mold, the failure rate of this synchronous laminated injection mold is reduced by 75% (the CCD cameras 1212 arranged at the front and rear can conduct real-time lubrication monitoring on the synchronous mold opening mechanism 11).

[0074] Cooling: First, the cooling liquid is respectively transmitted to the inside of the first cooling channel 1001 and the second cooling channel 1002. At this time, the first cooling channel 1001 can transmit the cooling liquid to the inside of the first cavity 4 and the second cavity 5 respectively, so as to quickly complete the synchronous cooling of the first cavity 4 and the second cavity 5, thus improving the cooling efficiency of the injection molded part first. Then, the second cooling channel 1002 can transmit the cooling liquid to the inside of the fixed mold plate 3 and the moving mold plate 6 respectively, so as to quickly complete the synchronous cooling of the fixed mold plate 3 and the moving mold plate 6, thus improving the cooling efficiency of the injection molded part again. Through the cooperation of the first cooling channel 1001 and the second cooling channel 1002, the synchronous cooling of both sides of the injection molded part can be quickly realized, and this efficient cooling system can significantly shorten the cooling time of the injection molded part;

[0075] Demoulding: First, control the moving die base plate 8 to move to the right through the driving component. The rightward movement of the moving die base plate 8 can prompt the synchronous die-opening mechanism 11 to quickly complete the synchronous die-opening of the first cavity 4 and the second cavity 5, thus quickly completing the die-opening of the double-layer cavity. Then, control the hydraulic cylinder 1304 to start, which can drive the first push plate 1302 and the first push rod fixing plate 1303 to move to the right simultaneously. The rightward movement of the first push rod fixing plate 1303 can drive the first left demoulding rod 1305 and the second left demoulding rod 1306 to move to the right simultaneously. The rightward movement of the first left demoulding rod 1305 can quickly complete the demoulding of multiple formed parts in a single layer, while the rightward movement of the second left demoulding rod 1306 can quickly complete the demoulding of the left-side waste. Then, control the hydraulic cylinder 1310 to start, which can drive the right push rod 1309 to move to the left. The leftward movement of the right push rod 1309 can drive the second push plate 1307 and the second push rod fixing plate 1308 to move to the left simultaneously. The leftward movement of the second push rod fixing plate 1308 can drive the first right demoulding rod 1311 and the second right demoulding rod 1312 to move to the left simultaneously. The leftward movement of the first right demoulding rod 1311 can quickly complete the demoulding of the formed parts in the other layer, while the leftward movement of the second right demoulding rod 1312 can quickly complete the demoulding of the right-side waste. Through the coordinated use of the hydraulic cylinder 1304 and the hydraulic cylinder 1310, the demoulding of the double-layer formed parts can be quickly completed;

[0076] Lubrication of the synchronous die-opening mechanism 11: First, control the CCD camera 1212 to turn on to observe the rust and damage degrees between the die-opening rack 1103 and the die-splitting gear 1106 in real time. When rust appears or oil is lacking at the connection between the gear and the rack, the main pipeline 1210 can quantitatively transfer the lubricating oil in the liquid storage barrel 1209 to the inside of the transfer pipeline 1203. At this time, control the oil delivery cylinder 1207 to start, which can drive the inner push plug 1208 to push the lubricating oil. When the inner ring plate 1205 disengages from the closure of the liquid delivery pipe 1201, the liquid delivery pipe 1201 can transfer the lubricating oil in all directions to the connection between the die-opening rack 1103 and the die-splitting gear 1106, so as to ensure that the lubricating oil can be evenly transferred to the surface of the moving die-opening structure. And by precisely controlling the transfer amount of the lubricating oil, it is ensured that the surfaces of the rack and the gear are always in the best lubrication state. After the delivery is completed, control the oil delivery cylinder 1207 to start again. The start of the oil delivery cylinder 1207 can drive the inner push plug 1208 to return to the initial position. At this time, the elastic force of the return spring 1204 will push the inner ring plate 1205 back to the initial position. At this time, the inner ring plate 1205 can close the liquid delivery pipe 1201 again and ensure that the space between the inner ring plate 1205 and the inner push plug 1208 is a quantitative space. At this time, the main pipeline 1210 can quantitatively transfer the lubricating oil in the liquid storage barrel 1209 to the inside of the transfer pipeline 1203 again, and prompt the lubrication component 12 to be continuously used.
