The specific meaning of the above terms in the embodiments of the present utility model will be understood by those of ordinary skill in the art according to specific circumstances.

In some embodiments of the present utility model, as shown in fig. 1-3, a durable cell phone case molding injection mold is provided, including a mold base 100. The durable cell phone case molding injection mold further includes a mold cover 200. The edge of the mold cover 200 is provided with a clamping groove 210. The clamping groove 210 includes an upper groove 211 and a lower groove 212. The upper tank 211 includes an outer tank 213 and an inner tank 214 connected to each other. The outer groove 213 is disposed above the lower groove 212 and is larger than the lower groove 212. The outer groove 213, the inner groove 214, and the lower groove 212 are each provided with a cushion 300.

When the clamping jaw clamps the die cover 200, the upper layer groove 211 and the lower layer groove 212 provide force points for clamping the clamping jaw, the clamping jaw clamps the die cover 200 more firmly, the die cover 200 is not easy to shake in the clamping process, friction with the clamping jaw is avoided, unnecessary abrasion is avoided, and durability of the surface of the die is improved.

When the clamping jaw clamps the mold cover 200, the buffer pad 300 can effectively separate the upper layer groove 211 from the lower layer groove 212, and prevent the clamping jaw from directly contacting with the inner walls of the upper layer groove 211 and the lower layer groove 212, thereby effectively protecting the upper layer groove 211 and the lower layer groove 212. Even after multiple clamping of the clamping jaw, the upper layer groove 211 and the lower layer groove 212 can still be tightly matched with the clamping jaw, so that the clamping jaw can clamp the die cover 200 sufficiently.

It should be noted that, when the cushion pad 300 is worn, the user can replace the cushion pad in time, so as to ensure that the cushion pad 300 and the clamping jaw maintain close contact. Specifically, the cushion 300 is made of an elastic rubber material. The elastic rubber material can bring about a better cushioning property, and can convert the rigid contact between the clamping jaw and the inner walls of the outer groove 213, the inner groove 214 and the lower groove 212 into a flexible contact, and can also prevent the inner walls of the grooves from being scratched or damaged by the clamping jaw.

In other embodiments of the present utility model, as shown in fig. 2, the mold cap 200 is provided with a plurality of alignment posts 220. The die holder 100 is provided with a plurality of alignment slots 110 corresponding to the alignment posts 220. When the mold is closed, the alignment posts 220 are engaged with the alignment grooves 110, so that the mold base 100 and the mold cover 200 are tightly closed.

Specifically, in the present embodiment, the specific number of the alignment posts 220 and the alignment slots 110 is 4, and the alignment posts are respectively disposed at four corners of the die cover 200 and four corners of the die holder 100. And the alignment post 220 is lamellar. After the alignment posts 220 are inserted into the alignment slots 110, the alignment posts 220 cover the alignment slots 110, thereby allowing the die cover 200 to clamp the die holder 100.

In other embodiments of the present utility model, as shown in fig. 1, the upper end surface of the die holder 100 is provided with a clearance groove 120 for facilitating gripping by the clamping jaw. Upon demolding, a portion of the jaws extend into the clearance groove 120. When the clamping jaw moves upwards, the clamping jaw can effectively support the die cover 200 from bottom to top, and the purpose of rapid demoulding is achieved.

In other embodiments of the present utility model, as shown in fig. 3, a plurality of buffers 400 are provided at the bottom of the die holder 100. Specifically, the die holder 100 may be mounted in a rubber sleeve (not shown), and the rubber sleeve can effectively wrap the die holder 100, so as to achieve the purpose of protecting the die holder 100. When the die holder 100 is installed in the rubber sleeve, the buffer member 400 can be located between the die holder 100 and the rubber sleeve, and can play a role in buffering. When the mold cover 200 is closed, the buffer member 400 can effectively buffer the pressure generated during the closing process, so as to avoid the occurrence of the situation that the rubber sleeve is deformed or even damaged by pressure during the long-term closing process.

Further, the buffer 400 is preferably a spring or a rubber pad, etc.

In other embodiments of the present utility model, as shown in fig. 1, the inner walls of the outer groove 213, the inner groove 214, and the lower groove 212 are provided with anti-slip stripes 500. The anti-slip stripes 500 can increase friction between the clamping jaws and the inner walls of the outer groove 213, the inner groove 214, and the lower groove 212, so that the clamping jaws can firmly clamp the mold cover 200, and the mold cover 200 is prevented from falling off during the clamping process.

In other embodiments of the present utility model, the lower bottom surface of the die holder 100 is provided with a fitting groove 130 and a plurality of screw holes 140. The die holder 100 can be fixedly installed in the rubber bush through the fitting groove 130 and the screw hole 140. Specifically, the number of the threaded holes 140 is four, the threaded holes 140 are disposed at four corners of the bottom of the die holder 100, and the assembly slot 130 is disposed at the center of the bottom of the die holder 100.

In other embodiments of the present utility model, the die holder 100 is provided with an electromagnet (not shown). The mold cover 200 is provided with an iron block (not shown). When the mold is completed, an electromagnet and iron block are added in order to avoid the unexpected separation of the mold base 100 and the mold cover 200. When the electromagnet is electrified, magnetism is generated, so that the iron block is adsorbed. The die cover 200 and the die holder 100 can be firmly connected together under the action of magnetic force, and are not easy to separate. Specifically, in some embodiments, the electromagnet is disposed inside the die holder 100, and the iron block is disposed inside the die cover 200 corresponding to the electromagnet.

In other embodiments of the present utility model, as shown in fig. 2, the upper end surface of the die holder 100 is provided with a plurality of die cavities 150. The upper end surface of the mold cover 200 is provided with an injection port 230 and an exhaust gas discharge port 240. The injection port 230 and the exhaust vent 240 are in communication with the mold cavity 150. The heated and melted plastic is injected into the mold cavity 150 through the injection port 230, and the shape of the mobile phone case can be formed after the plastic is cooled. The exhaust gas outlet 240 can effectively exhaust the harmful gas emitted by the heated plastic, reduce the odor of the formed mobile phone cover, ensure the environmental protection and not harm the physical health of the user. Specifically, an exhaust gas absorbing means may be provided in the vicinity of the exhaust gas discharge port 240 so as to timely absorb the exhaust gas discharged from the exhaust gas discharge port 240.

In other embodiments of the present utility model, the upper end surface of the mold cover 200 is made of rubber. The upper end surface of the mold cover 200 formed by rubber can effectively isolate heat, thereby avoiding the occurrence of accidental scalding of a user.
