[0002] Nowadays, smartphones have become an extremely popular electronic device. In order to protect them during daily use, the usage rate of mobile phone accessories such as protective cases and tempered films has greatly increased, and the production and processing industry of such accessories has also developed.

[0003] Mobile phone cases are mostly made of leather, plastic, rubber and other materials after being stamped and shaped by molds. Taking leather as an example, before stamping and shaping, the raw materials need to be cut according to the model of the mobile phone and the corresponding shape and size of the model.

[0004] Cutting can be done using the corresponding molds. The uncut raw material is placed between the inner mold and the outer mold. The inner mold squeezes the raw material into the outer mold and cuts the raw material according to the shape of the outer mold cavity during the extrusion process to perform shaping and cutting. However, during cutting, the outer mold will rub against the inner wall of the inner mold when entering and exiting the inner mold, causing wear between the two and affecting the service life of both.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-6 As shown, the utility model provides a shaping and cutting device, including an inner mold 8, two symmetrical half outer molds 9 are arranged at the bottom of the inner mold 8, and the two half outer molds 9 are combined to form a complete outer mold, and the bottom edge of the inner mold 8 is narrowed into a knife-shaped shape, which is convenient for cutting the raw material;

[0027] Two slide bars 2 are provided at the bottom of the inner mold 8, and the semi-outer mold 9 is located between the two slide bars 2. Mounting plates 901 are fixedly provided on both the front and rear sides of the semi-outer mold 9. A slide seat 902 is provided at the bottom of the mounting plate 901 through bolts. The slide seat 902 is sleeved on the outer end of the slide bar 2 on the corresponding side. The semi-outer mold 9 can be disassembled and replaced according to the model of the mobile phone case. The semi-outer mold 9 drives the slide seat 902 to slide on the outer end of the slide bar 2 during the movement;

[0028] A cylinder 3 is provided on the side of the half outer mold 9 away from the other half outer mold 9 , and the extension and retraction of the cylinder 3 can control the movement of the half outer mold 9 .

[0029] Before cutting, the two half outer molds 9 are pushed by the cylinder 3 so that the two half outer molds 9 are in a merged state, and the unsheared raw material is placed on the top of the merged half outer mold 9. At this time, the inner mold 8 moves downward and contacts the raw material. The inner mold 8 squeezes the raw material into the mold cavity of the outer mold and uses the sharp edge of its bottom end to cut the raw material while squeezing. After cutting, the raw material enters the mold cavity surrounded by the two half outer molds 9 along with the inner mold 8, and the outer end of the inner mold 8 contacts the inner wall of the mold cavity. After the shearing is completed, the inner mold 8 will move upward for the next shearing. However, before the inner mold 8 moves up, the two half outer molds 9 are first controlled to separate by the cylinder 3 so that the outer end of the inner mold 8 no longer contacts the half outer mold 9, and then the inner mold 8 moves up. After moving up, the cylinder 3 controls the two half outer molds 9 to merge again. In this way, the inner mold 8 no longer rubs against the mold cavity when it is moved out of the mold cavity, which reduces the wear of the inner mold 8 and the half outer mold 9 during use and extends the service life of the two.

[0030] When the half outer mold 9 is merged, in order to cushion the cylinder 3, as shown in FIG. Figure 1 , 6 As shown, a base 1 is provided at the bottom of the semi-external mold 9, two vertical plates 4 are fixedly provided at the top of the base 1, and two ends of the slide rod 2 are fixedly connected to the two vertical plates 4 respectively.

[0031] The vertical plate 4 is provided with a guide rod 12 penetrating the vertical plate 4, and both ends of the guide rod 12 are fixed with end plates 13, and the cylinder 3 is arranged on the end plate 13 close to the semi-external mold 9;

[0032] A spring 14 is fixedly provided on one side of the vertical plate 4 away from the half outer mold 9, and one end of the spring 14 is fixedly connected to the end plate 13 away from the half outer mold 9. The elastic force of the spring 14 plays a buffering role when the cylinder 3 controls the two half outer molds 9 to merge.

[0033] When the cylinder 3 pushes the two half outer molds 9 to contact and merge with each other, in the subsequent shearing process, if the half outer mold 9 is subjected to too much force when it is squeezed by the inner mold 8 and the raw material, the pressure will push the cylinder 3 in the opposite direction, and then push the guide rod 12, and make the spring 14 stretched, so as to use the elastic force of the spring 14 to buffer the cylinder 3 and prevent the cylinder 3 from being damaged due to excessive force.

[0034] The size of the inner mold 8 is different for different models of mobile phone cases, such as Figure 1 , 2 As shown in , 4 and 5, a hydraulic cylinder 5 is provided at the top of the inner mold 8, and the extension and retraction of the hydraulic cylinder 5 can control the up and down movement of the inner mold 8. The piston rod of the hydraulic cylinder 5 is detachably connected to the inner mold 8 through a connecting assembly, and the piston rod of the cylinder 3 is detachably connected to the corresponding half-outer mold 9 through a connecting assembly.

[0035] A column 7 is fixedly provided on the top of the base 1 , and the column 7 is located at the rear side of the vertical plate 4 . A crossbeam 6 is fixedly provided on the front side of the column 7 , and the hydraulic cylinder 5 is detachably mounted on the bottom end of the crossbeam 6 .

[0036] The connecting assembly includes a sleeve 10 sleeved on the outer ends of the piston rods of the hydraulic cylinder 5 and the air cylinder 3. The sleeves 10 in the two connecting assemblies are respectively fixed on the top of the inner mold 8 and one side of the semi-outer mold 9. The sleeve 10 is provided with a fixing pin 11 that passes through the sleeve 10 and the corresponding piston rod, which is convenient for installation and disassembly.

[0037] An air pipe 15 is fixedly provided at the top of the inner mold 8, and an air pump 16 is fixedly provided on the air pipe 15. When the raw materials are stuck inside the inner mold 8 after being cut, the raw materials can be blown off by inflation.

[0038] The inner mold 8 is controlled to move up and down by the extension and retraction of the hydraulic cylinder 5, and the piston rod of the hydraulic cylinder 5 extends to the inside of the sleeve 10 and is connected to the sleeve 10 through the fixing pin 11, so as to connect the inner mold 8 and the hydraulic cylinder 5, and connect the cylinder 3 and the semi-outer mold 9 in the same way. This method is easy to install and disassemble, and is convenient for replacing the inner mold 8 and the semi-outer mold 9. When the cut raw material is stuck in the inner mold 8 during the shearing process, the inner mold 8 is inflated through the air pipe 15 and the air pump 16, and the raw material is blown downward by the force of the air flow to achieve demolding.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
