[0006] The mold body has two first ventilation holes, which are spaced apart along a first direction and are connected along a second direction. The first direction is the length direction of the mold body, and the second direction is the height direction of the mold body.
[0007] Two pressure blocks are disposed opposite each other on opposite sides of the mold body along the first direction, and the pressure blocks are provided with a second vent hole that extends through the first direction;
[0008] Two scrapers are respectively sandwiched between the mold body and the corresponding pressure block, and both ends of the scrapers extend beyond the edge of the mold body along the third direction. The scrapers are provided with a third vent hole that extends through the first direction. The two ends of the third vent hole are respectively connected to the second vent hole and the first vent hole. The third direction is the thickness direction of the mold body.
[0009] The processing housing is adapted to the shearing mold, and the processing housing can be snapped onto the shearing mold for processing. During the processing, the scraper can scrape off the powder and debris at the corner of the inner side wall of the processing housing. When the processing housing is detached from the shearing mold, the gas entering from the end away from the processing housing through the first vent can enter the gap between the mold body and the processing housing through the third vent and the second vent, blowing off the powder and debris.
[0010] As an optional technical solution for shearing molds, the pressure block has a set of ventilation grooves recessed on the side surface opposite to the mold body, and the set of ventilation grooves is connected to the second ventilation hole.
[0011] As an optional technical solution for the shearing mold, the ventilation groove group includes a first ventilation groove and a second ventilation groove. The first ventilation groove is disposed on the edge of the pressure block along the third direction and extends along the second direction. The second ventilation groove extends along the third direction and its two ends are respectively connected to the second ventilation hole and the first ventilation groove.
[0012] As an optional technical solution for shearing molds, there are multiple second vent holes and multiple third vent holes. The multiple second vent holes are evenly spaced along the second direction, and the second vent holes correspond one-to-one with the third vent holes.

Bolts are sequentially passed through the first connecting hole, the second connecting hole, and the third connecting hole to connect the pressure block, the scraper, and the mold body.
[0014] As an optional technical solution for shearing molds, the mold body has a first groove on one side surface facing the processing housing, and the first vent hole is located at the bottom of the first groove.
[0015] As an optional technical solution for shearing molds, the mold body is provided with a second groove on the opposite two sides along the third direction.
[0016] The second objective of this invention is to provide a cutting mechanism that can scrape off and blow away processing powder from the inner wall of a processing housing.
[0017] To achieve this objective, the present invention adopts the following technical solution:
[0018] The shearing mechanism includes a base and a plurality of shearing molds, wherein the plurality of shearing molds are spaced apart on the base along the third direction.
[0019] As an optional technical solution for the cutting mechanism, the cutting mechanism further includes an upper cover, which covers the cutting mold and is connected to the base. The upper cover is provided with a second air inlet pipe, and the base is provided with an air suction hole on the side facing the cutting mold.
[0020] As an optional technical solution for the shearing mechanism, there are multiple suction holes, which are spaced apart along the third direction, and the shearing mold is located between two adjacent suction holes.

[0022] The shearing mold provided by this utility model includes a mold body, two pressure blocks, and two scrapers. The two pressure blocks are arranged opposite each other on opposite sides of the mold body along a first direction. The scrapers are sandwiched between the mold body and the corresponding pressure blocks, and the pressure blocks fix the scrapers to the mold body. Both ends of the scrapers extend beyond the edge of the mold body along a third direction, allowing the processing housing to be attached to the shearing mold for processing. During processing, the scrapers can remove powder debris from the corners of the inner sidewall of the processing housing, improving the processing quality of the processing housing, and the method of removing powder debris is simple. Since the mold body is provided with two first vent holes, and the pressure blocks and scrapers are respectively provided with second and third vent holes, when the processing housing is detached from the shearing mold, gas is blown in from one end of the first vent hole. The gas entering the first vent hole is then blown into the gap between the processing housing and the shearing mold through the third and second vent holes, which can blow off the powder debris, further removing the processing powder debris inside the processing housing and improving the processing quality of the processing housing.

[0035] This embodiment provides a shearing mold that can remove processing powder from the inner wall of the processing housing, and the removal method is simple.
[0036] Specifically, such as Figures 1 to 3As shown, the shearing mold includes a mold body 100, two pressure blocks 200, and two scrapers 300. The mold body 100 has two first vent holes 110, spaced apart along a first direction and connected along a second direction, the first direction being the length direction of the mold body 100 and the second direction being the height direction of the mold body 100. The two pressure blocks 200 are positioned opposite each other on opposite sides of the mold body 100 along the first direction, and each pressure block 200 has a second vent hole 210 connected along the first direction. The two scrapers 300 are respectively sandwiched between the mold body 100 and the corresponding pressure block 200, with both ends of the scrapers 300 extending beyond the edge of the mold body 100 along a third direction. Each scraper 300 has a third vent hole 310 connected along the first direction, with both ends communicating with the second vent hole 210 and the first vent hole 110, respectively. The third direction is the thickness direction of the mold body 100. The processing housing is compatible with the shearing mold and can be snapped onto the shearing mold for processing. During processing, the scraper 300 can scrape off the powder debris from the corners of the inner wall of the processing housing. As the processing housing detaches from the shearing mold, the gas entering from the end away from the processing housing through the first vent 110 can enter the gap between the mold body 100 and the processing housing through the third vent 310 and the second vent 210, blowing off the powder debris.
[0037] Based on the above design, two pressure blocks 200 are positioned opposite each other on opposite sides of the mold body 100 along the first direction. A scraper 300 is sandwiched between the mold body 100 and the corresponding pressure block 200, with the pressure block 200 fixing the scraper 300 to the mold body 100. Both ends of the scraper 300 extend beyond the edge of the mold body 100 along the third direction. During the processing of the machining housing by fastening it to the shearing mold, the scraper 300 can scrape away the powder and debris from the corners of the inner sidewall of the machining housing, improving the processing quality of the machining housing, and the method of removing powder and debris is simple. The mold body 100 is provided with two first vent holes 110, and the pressure block 200 and scraper 300 are respectively provided with second vent holes 210 and third vent holes 310. During the process of the processing shell separating from the shearing mold, gas is blown in from one end of the first vent hole 110. The gas entering the first vent hole 110 is then blown into the gap between the processing shell and the shearing mold through the third vent hole 310 and the second vent hole 210, which can blow off the powder and further remove the processing powder in the processing shell, thereby improving the processing quality of the processing shell.
[0038] In this embodiment, the scraper 300 can be a brush or sandpaper; the introduced gas can be plasma gas.
[0039] In this embodiment, the first vent 110 is connected to a first air inlet pipe 400 at the end opposite to the processing housing, and gas is blown in from the first air inlet pipe 400.
[0040] Optionally, the pressure block 200 has a ventilation groove group recessed on the side surface opposite to the mold body 100. The ventilation groove group is connected to the second ventilation hole 210. The ventilation groove group can increase the gap between the surface of the pressure block 200 and the inner wall of the processing shell, so that gas can flow in the processing shell and blow off the powder.
[0041] Specifically, the ventilation groove group includes a first ventilation groove 221 and a second ventilation groove 222. The first ventilation groove 221 is disposed on the edge of the pressure block 200 along the third direction and extends along the second direction. The second ventilation groove 222 extends along the third direction and its two ends are respectively connected to the second ventilation hole 210 and the first ventilation groove 221. The gas coming out of the second ventilation hole 210 enters the first ventilation groove 221 through the second ventilation groove 222, and guides the gas to the corner of the inner side wall of the processing housing, thereby making it easier to blow off the dust.
[0042] The arrow points in the direction of gas flow.
[0043] Optionally, there are multiple second vent holes 210 and multiple third vent holes 310. The multiple second vent holes 210 are evenly spaced along the second direction. The second vent holes 210 and the third vent holes 310 correspond one-to-one, and can evenly blow away powder along the second direction.
[0044] For example, the number of second vent holes 210 can be two, three, four, or six. In this embodiment, the number of second vent holes 210 is two.
[0045] Optionally, the mold body 100 has a first groove 120 on the side surface facing the processing shell, and a first vent hole 110 is provided at the bottom of the first groove 120 to increase the gap between the top of the mold body 100 and the inner top wall of the processing shell, so that the gas in the first vent hole 110 can diffuse from the top of the mold body 100 to the surrounding side walls of the mold body 100.
[0046] Furthermore, a plurality of through holes are provided at the bottom of the first groove 120 and between the two first vent holes 110. For example, the number of through holes can be two, three, or four, etc. In this embodiment, the number of through holes is three.
[0047] Optionally, the shearing mold is provided with an arc around the top of the second direction to increase the gap between the shearing mold and the processing housing, so that the gas in the first vent hole 110 (first groove 120) can be blown to the periphery of the shearing mold.
[0048] Optionally, the mold body 100 is provided with a second groove 130 on the opposite two sides along a third direction, which can increase the gap between the surface of the mold body 100 and the processing shell, and reduce the weight of the mold body 100, thus saving costs.
[0049] Optionally, the pressure block 200 is provided with a first connecting hole 230, the scraper 300 is provided with a second connecting hole 320, and the mold body 100 is provided with a third connecting hole. Bolts are sequentially passed through the first connecting hole 230, the second connecting hole 320 and the third connecting hole to connect the pressure block 200, the scraper 300 and the mold body 100. The bolt connection is simple and has high connection strength.
[0050] In this embodiment, each side of the pressure block 200 is provided with two first connecting holes 230. The two first connecting holes 230 are located at both ends of the pressure block 200 along the second direction, that is, the second vent hole 210 is located between the two first connecting holes 230.
[0051] Optionally, the mold body 100 is recessed on the side facing the pressure block 200, and the pressure block 200 is protruded on the side facing the mold body 100. The protrusion is adapted to the shape of the slot and can be locked in the slot. The scraper 300 is clamped between the protrusion and the slot, increasing the connection strength between the mold body 100 and the pressure block 200.
[0052] This embodiment also provides a shearing mechanism that can scrape off and blow away processing dust from the inner wall of the processing housing.
[0053] Specifically, such as Figure 4 and Figure 5 As shown, the shearing mechanism includes a base 2 and multiple shearing molds 1. Exemplarily, the number of shearing molds 1 can be two, three, four, or five. In this embodiment, the number of shearing molds 1 is five. Multiple shearing molds 1 are spaced apart on the base 2 along a third direction. The base 2 is used to fix the shearing molds 1, and the molds can simultaneously process the housing. During the processing of the housing, which is attached to the shearing mold 1, the scraper 300 can scrape away the powder and debris from the corners of the inner wall of the housing, improving the processing quality of the housing, and the method of removing powder and debris is simple. The mold body 100 is provided with two first vent holes 110, and the pressure block 200 and the scraper 300 are respectively provided with second vent holes 210 and third vent holes 310. During the process of the processing shell separating from the shearing mold 1, gas is blown in from one end of the first vent hole 110. The gas entering the first vent hole 110 is then blown into the gap between the processing shell and the shearing mold 1 through the third vent hole 310 and the second vent hole 210, which can blow off the powder and further remove the processing powder in the processing shell and improve the processing quality of the processing shell.
[0054] Furthermore, the shearing mechanism also includes an upper cover 3, which covers the shearing mold 1 and is connected to the base 2. The upper cover 3 is provided with a second air inlet pipe, and the base 2 is provided with an air suction hole 21 on the side facing the shearing mold 1. Gas is introduced into the second air inlet pipe and drawn in through the air suction hole 21, which can discharge the powder falling from the processing shells corresponding to the multiple shearing molds 1.
[0055] Furthermore, there are multiple suction holes 21, which are spaced apart along a third direction. The shearing mold 1 is located between two adjacent suction holes 21 to increase the discharge speed of powder.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
