The outer edge of the flat plate is consistent with the shape of the engine. There are multiple through holes in the flat plate, and the number of through holes is consistent with the number of engine cylinder blocks.

[0003] The relevant cylinder head gasket stamping die consists of an upper die and a lower die. The lower die is fixed, while the upper die is driven by a power element such as a hydraulic cylinder. The upper die is positioned above the lower die and reciprocates vertically. The lower die is provided with a protrusion, and the upper die is provided with a groove. The shape of the protrusion and groove corresponds to the cross-sectional shape of the cylinder head gasket to be produced. The user can lower the upper die by placing a steel plate horizontally between the upper and lower dies. The upper and lower dies work together to squeeze the steel plate, thereby pressing a flat plate with the same shape as the workpiece, completing the production process.

[0004] The above-mentioned related technical solutions have the following defects: the specifications and sizes of engines vary, and the production of cylinder gaskets requires the preparation of molds of various sizes and shapes. The mold manufacturing cost is high, which results in high production costs. Utility Model Content

[0005] In order to reduce the cost of producing cylinder gaskets of different shapes, the present application provides a four-cylinder block mold.

[0006] The four-cylinder block mold provided in this application adopts the following technical solution:

[0007] A four-cylinder block mold includes a movable mold and a fixed mold. The movable mold includes a pressure plate and multiple modules. The modules are detachably connected to the pressure plate. The fixed mold includes a base plate and a concave and convex mold. The concave and convex molds are detachably connected to the base plate. The pressure plate and the base plate are parallel to each other. The movable mold moves back and forth in a straight line and abuts against the fixed mold. The shape of the module corresponds to the cross-sectional shape of the concave and convex mold.

[0008] By adopting the above technical solution, by arranging modules on the pressing plate and arranging convex and concave dies on the bottom plate, when the steel plate is placed between the movable die and the fixed die, the movable die moves and abuts the steel plate, thereby pressing out holes on the workpiece corresponding to the shapes of the modules and the convex and concave dies, thereby achieving the stamping effect. The user can adjust the size of the stamped workpiece by replacing the convex and concave dies and modules, thereby reducing the amount of mold production. When producing cylinder gaskets of various shapes, it can be completed by replacing some modules, thereby reducing production costs.

[0009] Optionally, a guide sleeve is provided on the movable mold, and the guide sleeve includes sleeve one, sleeve two and a spring. Sleeve one is vertically fixed on the pressure plate, sleeve two is vertically fixed on the base plate, sleeve one is installed and slidably connected to sleeve two, and the spring is installed on sleeve two. One end of the spring abuts against the base plate, and the other end abuts against sleeve one.

[0010] By adopting the above technical solution, a guide sleeve is set on the movable mold, so that the guide sleeve plays the role of guiding and limiting, reducing the probability of horizontal deviation of the movable mold relative to the fixed mold, thereby making the positions of the module and the concave and convex molds always correspond, and the processed workpiece has higher precision.

[0012] By adopting the above technical solution, a closed frame structure is formed by using blocks. When the movable mold contacts the fixed mold, the frame formed by the blocks is sleeved on the outside of the concave and convex molds. At this time, the blocks and the outer edges of the concave and convex molds jointly cut the steel plate, cutting out the outer edge of the cylinder gasket on the steel plate. The insert can be inserted into the through hole in the middle of the concave and convex molds, thereby punching out a through hole on the cylinder gasket to complete the processing work.

[0013] Optionally, a mounting groove is provided on the pressing plate, the mounting groove is a sunken groove, and the blocks are arranged to fit the inner wall of the mounting groove.

[0014] By adopting the above technical solution, by arranging the installation groove on the pressure plate, the blocks are arranged along the inner wall of the installation groove, which makes it convenient for users to install the blocks. By adjusting the size of the blocks, cylinder gaskets with different side lengths can be punched out. When the blocks are abutted against the steel plate for stamping, the inner wall of the installation groove clamps the blocks, which can reduce the chance of the blocks slipping in the horizontal direction.

[0015] Optionally, a matching hole is opened on the bottom plate, and the matching hole passes through the bottom plate, and the position of the matching hole corresponds to the position of the insert.

[0016] By adopting the above technical solution, by opening a matching hole on the base plate, when the insert punches a through hole on the workpiece, the punched waste can fall under the base plate through the matching hole, thereby making it convenient for users to collect and process the waste.

[0018] By adopting the above technical solution, an upper hitting plate is set on the pressure plate so that the upper hitting plate can be pressed on the upper surface of the workpiece. When the movable mold and the fixed mold punch the steel plate, the upper hitting plate can abut against the upper surface of the steel plate and slide automatically. The user can punch out cylinder gaskets of different thicknesses by installing upper hitting plates of different thicknesses on the pressure plate.

[0019] Optionally, a plurality of stepped holes are provided on the upper punching plate, bolts are provided in the stepped holes, and the bolts are threadedly connected to the pressure plate.

[0020] By adopting the above technical solution, a stepped hole is opened on the upper punching plate, and a bolt is arranged in the stepped hole.

The concave and convex molds are arranged in the through hole of the discharge plate. The discharge plate is laid flat on the base plate. A plurality of latches are arranged on the base plate. The latches are arranged perpendicular to the base plate. The latches pass through the discharge plate and are detachably connected to the discharge plate.

[0022] By adopting the above technical solution, a pin is set on the bottom plate and a stripping plate is set on the pin. When the movable mold and the fixed mold punch the cylinder gasket, the waste on the outer edge of the cylinder gasket falls on the stripping plate. The user can lift the stripping plate to disconnect the stripping plate from the bottom plate, thereby making it convenient for the user to handle the waste on the stripping plate and facilitate the recycling of waste.

By controlling the pressing plate 11 to press downward, the module 12 can contact the concave-convex mold 22, and then the workpiece set between the movable mold 1 and the fixed mold 2 is punched and processed. The user installs modules 12 of different shapes on the pressing plate 11 and adjusts the shape of the concave-convex mold 22 installed on the base plate 21, so that the shape of the concave-convex mold 22 always corresponds to the pattern formed by the modules 12, thereby being able to produce and process workpieces of different shapes and reduce the cost of making templates.

[0037] Reference Figure 3 and Figure 4 Module 12 includes multiple blocks 121 and multiple inserts 122. The blocks 121 are joined together to form a frame structure. Multiple inserts 122 are positioned within the space enclosed by the blocks 121. Both the blocks 121 and the inserts 122 are removably connected to the platen 11 via bolts. When the movable mold 1 falls, the blocks 121 contact the outer walls of the concave and convex molds 22, thereby cutting the workpiece into a sheet material having a shape corresponding to the pattern enclosed by the blocks 121. The inserts 122 can be cylindrical or irregularly shaped. The inserts 122 are inserted into holes defined in the concave and convex molds 22, and are used to cut through holes of various shapes in the workpiece.

[0038] Reference Figure 1 、 Figure 4 and Figure 5 The pressing plate 11 includes a connecting plate 111, a pad 112 and a mounting plate 113. The connecting plate 111 and the mounting plate 113 are arranged parallel to each other, and the pad 112 is arranged between the connecting plate 111 and the mounting plate 113. A cavity is formed between the connecting plate 111 and the mounting plate 113. The connecting plate 111 is used to connect to power parts such as hydraulic cylinders, and the module 12 is detachably connected to the mounting plate 113. A mounting groove 114 is provided on the lower bottom surface of the mounting plate 113. The mounting groove 114 is a sink structure, and the blocks 121 are arranged along the inner wall of the mounting groove 114. The mounting groove 114 plays a supporting role, which can keep the block 121 in a stable position when stamping the workpiece, reduce the probability of the block 121 moving or deforming, and ensure the dimensional accuracy of the workpiece. The user installs blocks 121 of different widths in the mounting groove 114 to change the size of the space enclosed by the inner wall of the block 121, thereby achieving the effect of adjusting the size of the stamped workpiece product.
