The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts of different shapes and sizes.

[0003] After the plastic is formed in the mold, the staff is generally required to start the equipment to separate the die and the punch, and then take out the molded product. The plastic product formed in the mold is easy to stick to the metal surface, and it is easy to be damaged when the staff manually takes it out. Therefore, it does not meet the existing needs, and a high-performance engineering plastic molding mold is proposed. Utility Model Content

[0022] 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.

[0023] In order to solve the problem that plastic products formed in the mold are easy to stick to the metal surface and are easily damaged when people take them out manually, please refer to Figure 1-5 , an embodiment of the utility model is provided: a high-performance engineering plastic molding mold, including a lower template 2, and also including a limiting plate 4, the limiting plate 4 is located below the lower template 2, an upper template 1 is arranged above the lower template 2, a punch 201 is arranged inside the lower template 2, the punch 201 is connected to the lower template 2, a second waterway 202 is arranged inside the punch 201, a concave mold 101 is arranged inside the upper template 1, a top plate 6 is arranged above the upper template 1, the concave mold 101 is connected to the upper template 1, a first waterway 102 is arranged inside the concave mold 101, and a push rod 401 and a limiting column 402 are arranged on the side of the limiting plate 4. A bottom plate 3 is arranged below the limiting plate 4, a support 7 is arranged between the bottom plate 3 and the lower template 2, a guide column 701 is arranged inside the support 7, and the upper end of the guide column 701 extends upward and passes through the lower template 2, the upper template 1, the fixed plate 601 and the top plate 6 in sequence.

[0024] A gate 5 is provided above the top plate 6, a fixing plate 601 is provided below the top plate 6, a runner 501 is provided below the gate 5, a molding space is provided between the male mold 201 and the female mold 101, the upper end of the runner 501 is connected to the gate 5, the lower end of the runner 501 is connected to the molding space, and guide blocks 8 are provided at both ends of the first water channel 102 and the second water channel 202. The guide blocks 8 at both ends of the first water channel 102 are connected to the upper template 1, and the guide blocks 8 at both ends of the second water channel 202 are connected to the lower template 2. The first water channel 102 and the second water channel 202 have the same structure. The first water channel 102 passes through the upper template 1 to the inside of the female mold 101, and the second water channel 202 passes through the lower template 2 to the inside of the male mold 201.

[0025] After the plastic product is formed inside the mold, cooling water is injected into the first water channel 102 and the second water channel 202 to quickly reduce the temperature of the die 101 and the punch 201, so that the cooled surface of the plastic product becomes hard. Then, personnel control the equipment to separate the die 101 and the punch 201, and the ejector rod 401 ejects the plastic product from the middle of the plastic product. Compared with personnel taking out the plastic product from the edge, this reduces the possibility of damage to the plastic product when taking it out, thereby further improving production efficiency.

[0026] A hole groove 203 and a through groove 204 are arranged at the bottom of the lower template 2, the upper end of the push rod 401 is located inside the through groove 204, the upper end of the limiting column 402 passes through the hole groove 203 and extends upward to the side of the punch 201, the lower end of the push rod 401 is connected to the limiting plate 4, a spring 403 is arranged on the outside of the limiting column 402, the spring 403 is located between the lower template 2 and the limiting plate 4, L-shaped plates 404 are arranged on both sides of the limiting plate 4, a telescopic rod 405 is arranged at the bottom of the L-shaped plate 404, and the lower end of the telescopic rod 405 is connected to the bottom plate 3.

[0027] As the telescopic rod 405 pushes the limit plate 4 upward, the spring 403 is gradually compressed, so that the limit plate 4 can move at a relatively stable speed. At the same time, the limit plate 4 drives at least six push rods 401 to move upward. Multiple push rods 401 simultaneously apply uniform thrust to the plastic product, so that the plastic product can always be in a relatively horizontal state, avoiding deformation caused by collision between the plastic product and the mold, and further improving the quality of the plastic product.

[0028] Working principle: The plastic first enters the interior of the mold through the gate 5, and then enters the space between the die 101 and the punch 201 along the runner 501 for shaping. After the plastic product is formed, cooling water is injected into the first water channel 102 and the second water channel 202, thereby quickly reducing the temperature of the die 101 and the punch 201, making the cooling surface of the plastic product harden. Finally, personnel control the equipment to separate the die 101 and the punch 201, and the ejector rod 401 ejects the plastic product from the middle of the plastic product. Compared with personnel taking out the plastic product from the edge, this reduces the possibility of damage to the plastic product when taking it out, thereby improving production efficiency.
