New description: [New technical field] This is a plastic molding machine, especially a plastic molding machine that can change the size of the cavity and adjust its expansion surface according to different plastic materials. Mold structure. [Prior Art] Plastic molding machines are generally used in plastic raw material suppliers, which can form hot-melt plastic materials into long-block and solidified plastics through a mold structure, providing downstream plastics manufacturers with Demand to engage in subsequent processing. The replacement structure is generally disposed in the plastic molding machine. Referring to the sixth figure, the mold structure (60) is substantially in the form of a body having an opening (610) and a cross section at the center of the inner portion. The rectangular cavity (61) is further disposed at the inner bottom of the shai mold hole (61), and a injection hole (Μ) is formed through the through hole, and the side walls of the 5 sea injection hole (62) are respectively formed with openings. ( 610 ) gradually expanding out of the expansion surface (6 3 ); when used, the system will be hot-melt ~ Wang Sha publication bamboo - ι, τ several than eight mold points [6: in the 'by sticking to the expansion surface (63) The plastic material 2 is gradually expanded to fill the space of the cavity (61) and is injected by the plastic material = gradually open to the opening (610); the plastic material is cooled by the opening (61〇2/' can be cooled and solidified Solidified to form a long block, "because the cavity (61) of the mold structure (60) is solid," so if the size and thickness of the plastic are changed, the mold 5 M330180 ( 60) that is, it loses its available & In addition, different plastic materials have different viscosities, while the prior art mold structure (61) The expansion surface (63) cannot change the oblique angle according to different plastic materials, so it is often difficult to make the plastic material expand. [New content] The purpose of this creation is to provide a mold structure of a plastic molding machine. Can: change the size of the cavity and adjust the expansion surface according to different plastic materials 'to facilitate the molding of plastics. One for the above purpose' The mold structure of the creation plastic molding machine includes the template on the tr... the lower template and at least Between the upper template and the lower template, the upper template and the lower template are used to make the mold core in a removable manner; the clamping may be fixed or disassembled relative to the clamping, and the mold is fixed to the upper template. The linings can be arranged in plural; the surface of each mold core penetrates the cavity, and the cavity is obliquely formed with respect to the other opening of the opening: two: the two side walls of the ΐ枓 ΐ枓 hole are formed with a gradual opening ::Expansion surface; in the mold set in the plural, different molds can be /, have different thickness, cavity width or the angle of the expansion surface. Material:: use the second series according to plastic Thick and thick Degree 2 and plastic material are used to select a suitable mold core, and a multi-layer stack structure of the plastic material is injected into the cavity from the injection hole between the mold clamping plate and the lower template. After that, the hot melt gradually expands the width of the plastic material, so that it fills the mold expansion surface and 遂~2, and is gradually injected into the opening by the injection pressure of the plastic M330180 material. The mold structure of the machine provides the user with the expansion surface thereof. The angle of the oblique angle is therefore full and conforms to the viscous exhibition of different plastic materials. As the plastic molding of the creation changes the mold core and changes the size of the cavity and the different thickness requirements of the plastic, the plastic material is expanded. Embodiments Please refer to the first, second and third drawings. The structure includes an upper template (one is set on the upper template (丨0) and the lower mold: where is not the mold of the original plastic molding machine W), the next template ( 20) and at least a die (3 〇) between the plates (20), the upper die plate (10) is provided with a plurality of joint holes (11) (21) opposite to the circumferential side of the lower die plate (2〇), Locked by bolts (not shown) The upper jaw (i Q ) and the lower template (2 〇) are provided with heating means (Μ) on both sides and upper and lower surfaces, and the upper template (1〇) is provided on the surface of the end There is a temperature sensing device (24); the other end of the upper template (1〇) and the lower jaw plate (20) is a cooling portion, and the cooling portion of the upper template (丨〇) and the lower jaw plate (2〇) is laterally A plurality of flow channels (12) (23) are provided, and each μ channel (12) (23) is respectively connected to an external pipe () for supplying cold water; see also the upper template (1)顶) The top surface of the cooling part can be sighed with a plurality of pressure blocks (41), each of which has a certain weight; "Huirenren(30) system can be set in plural; each mold core (30) system Removably fixed between the upper template (10) and the lower template (20), the surface peripheral side of which is opposite to the upper template (10) and the lower template (20) by 7 M330180 number of combined holes ( 11) (21) penetrating is provided with a plurality of perforations (31) for the above-mentioned screw teeth, and the other mold cores (3 turns) penetrate to form a cavity (32) having an opening (mo) at one end, the cavity (32) Relative to opening (32〇) is provided with a injection hole (33) penetrating through the wall surface of the other end, and the injection hole (33) can be connected to a filling device (50) of a plastic molding machine (please refer to the fourth Figure 4 is a view; and a removable wedge-shaped block (34) is disposed on each of the side walls of the injection hole (33), and a locking hole (341) is formed on an outer side edge of the wedge-shaped block (34). The wedge block (34) can be relatively fixed to the mold core (30) by passing the bolt (342) through the mold core (3〇) and locking in the lock hole (341); and each wedge block body (34) an expansion surface (34〇) which is gradually inclined out toward the opening (320) is formed on the surface of the opening (32〇); among the plurality of mold cores (30), different mold cores (3〇) Each has a different thickness, a cavity (32) width or an angle of expansion (34〇), and the opening (320) of the cavity (32) is located opposite the upper template (10) / the lower template ( 2)) The cooling section, and the wedge-shaped block (34) of the mold core (3〇) is located in the heating device (22) opposite to the lower template (2〇). ... When using, it is based on the thickness and thickness requirements of the plastic, and the viscosity of the plastic material, which is suitable for the mold core (3〇), or the wedge type with the expansion surface (340) suitable for the oblique angle. a block body (34), and the mold core (30) is fixed between the upper mold plate (1〇) and the lower mold plate (2〇), and then the hot melt plastic material is injected into the mold from the injection hole (33). In the hole (32), the width of the plastic material is gradually expanded by adhering to the expansion surface (340) to fill the space of the cavity (32), and the δ M330180 is gradually opened to D by the injection pressure of the plastic material ( 320) output. The heating device (22) can heat and fix the plastic material on the expansion surface (10)) and ensure that the (four) U-coagulation cools the plastic material, so that the plastic (4) is cooled by the ^^二贝+J factory and solidified into a solid state, thereby forming Long block two: = (41) can be placed under the factory ... mold. ) Relative opening 2 The flatness of the surface of the plastic. It is known that the swaying affects the board (27b's because the mold core (3G) and the upper template ((4) and the lower mold form a gap], so the vapor contained in the plastic material can be, and Ensure that the speed and quality of the plastic are good. ^ See Figure 5, when the thickness requirement of the plastic is greater than the thickness of each mold, '彳 复 复 复 ( 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 30 1〇) to achieve the thickness requirement of the plastic mold with the lower template (2〇), and to close the excess injection hole (33) with a fixing member such as a screw 〇 [Simple description of the drawing] The first picture is an exploded perspective view of the creation. f The second picture is a perspective view of the implementation state of the creation. $4 is a side view of the implementation state of the creation.
