Description

Technical Field

[0001] The utility model relates to the field of wind wheel grinding tools, in particular to a middle wind wheel mold capable of separating a material handle. Background Art

[0002] The crossflow impeller is an air conditioner impeller. It consists of a motor shaft disc, a steel shaft disc and a plurality of middle discs connected between the motor shaft disc and the steel shaft disc. The motor shaft disc, the steel shaft disc and the middle disc are all integrally formed by injection molding. The quality of the injection mold plays a vital role in the quality of plastic products. Figure 1 The figure shows a central impeller that has been injection molded in the prior art. After the injection molding of the central impeller is completed and the mold is opened, the material handle 101 is taken out together with the impeller 100, and special equipment needs to be installed outside the mold to separate the material handle from the impeller. Since the material handle has been fully cooled outside the mold, the material handle is likely to remain and break on the impeller 100 during separation, affecting product quality and the cleanliness of the production site. Summary of the invention

[0003] In order to solve the above problems, the utility model aims to provide a middle impeller mold capable of separating the material handle, wherein the middle impeller mold can separate the material handle from the impeller when the mold is opened.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A wind wheel mold capable of separating a material handle, comprising an upper mold assembly and a lower mold assembly; the upper mold assembly comprises an upper mold base, and an upper mold core arranged in the upper mold base; the lower mold assembly comprises a lower mold base, and a lower mold core arranged in the lower mold base; the upper mold core and the lower mold core are connected to form a mold cavity for filling injection molding material and forming a wind wheel, and an injection molding channel for conveying injection molding material to the mold cavity and obtaining the material handle after injection molding; it is characterized in that: the lower mold assembly comprises a top plate mechanism, and a plurality of ejector rods for ejecting the wind wheel in the mold cavity, and a plurality of flow channel blocks for cutting the material handle from the wind wheel; the ejector rods and the flow channel blocks are both arranged above the ejector rods, and when the ejector rod mechanism moves upward, the flow channel block is first ejected and then the ejector rods, and the upper end of the flow channel block is aligned with the connection between the injection molding channel and the mold cavity.

[0006] The utility model adopts the above technical solution, which relates to a middle wind wheel mold that can separate the material handle. After the upper mold component and the lower mold component in the middle wind wheel mold are molded together for injection molding, the injection material is filled in the mold cavity to form the wind wheel, and the material handle is obtained after injection molding in the injection channel. Different from the prior art, in this solution, when the middle wind wheel injection molding is completed and the mold is opened, the injection molding equipment acts on the top plate mechanism. When the top plate mechanism moves upward, it first drives multiple flow channel blocks upward. The flow channel blocks move upward to separate the material handle from the wind wheel, and then continue to move upward to eject the wind wheel through the ejector rod. In this way, the middle wind wheel mold can achieve the separation of the material handle and the wind wheel when the mold is opened.

[0007] In a specific implementation scheme, the ejector mechanism includes an ejector plate and an ejector pin plate assembly, the lower end of the flow channel block abuts against the ejector plate, and the lower ends of the ejector pin and the ejector shaft pass through the ejector plate and are fixedly connected to the ejector pin plate assembly; when the mold is opened, the ejector plate moves up a certain distance and then drives the ejector pin plate assembly to move up. Furthermore, a guide screw is fixedly connected to the lower end of the ejector plate, and a guide chamber is constructed in the ejector pin plate assembly; the screw head of the guide screw is movably arranged inside the guide chamber, and the ejector plate drives the guide screw to move up, at which time the screw head of the guide screw moves up in the guide chamber until the screw head abuts against the ejector pin plate assembly, and then the ejector plate and the pin plate assembly move up synchronously.

[0008] Preferably, the ejector plate assembly comprises an upper ejector plate and a lower ejector plate, the upper ejector plate and the lower ejector plate are compounded together, and the ejector and the lower end of the ejector shaft are fixed between the upper ejector plate and the lower ejector plate.

[0009] In a further embodiment, the inner edge of the runner block is constructed to be inclined inward from bottom to top relative to the radial direction of the lower mold core, so that the runner block is constructed to be wide at the top and narrow at the bottom, and the space on the lower mold core to accommodate the runner block is adapted to its shape. In this scheme, when the runner block moves upward under the action of the ejector plate and cuts the material handle and the wind wheel, since the runner block is constructed into the above shape, the width of the runner block is smaller than the width of the space at the same height in the current state after the runner block moves upward compared to the space used for accommodating on the lower mold core, so that the runner block can avoid inward in the radial direction, thereby avoiding interference with the runner block when the ejector pin ejects the wind wheel or causing wear between the runner block and the runner block.

[0010] In summary, when the medium impeller mold is opened, the injection molding equipment acts on the top plate, and the top plate first drives multiple flow channel blocks upward, and the flow channel blocks move upward to separate the material handle from the impeller; at the same time, the guide screw fixed to the top plate moves upward, and the screw head of the guide screw moves upward in the guide chamber until the screw head and the ejector plate assembly are against each other; then, the top plate continues to move upward to eject the impeller through the ejector. In this way, the medium impeller mold can achieve the separation of the material handle and the impeller when the mold is opened. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 2 As shown, this embodiment relates to a medium wind wheel mold capable of separating a material handle, including an upper mold assembly and a lower mold assembly; the upper mold assembly includes an upper mold base 11, and an upper mold core 12 disposed in the upper mold base 11. The lower mold assembly includes a lower mold base 21, and a lower mold core 22 disposed in the lower mold base 21. The upper mold core 12 is docked with the lower mold core 22 to form a mold cavity for filling injection molding material and forming a wind wheel 100, and an injection molding channel for conveying injection molding material to the mold cavity and obtaining a material handle 101 after injection molding. After the upper mold assembly and the lower mold assembly in the medium wind wheel mold are combined for injection molding, the injection molding material is filled in the mold cavity to form the wind wheel 100, and the material handle 101 is obtained after injection molding in the injection molding channel.

[0020] Different from the prior art, the lower mold assembly of the present solution includes a top plate mechanism, a plurality of top rods 32 for ejecting the wind wheel 100 in the mold cavity, and a plurality of runner blocks 33 for cutting off the material handle 101 from the wind wheel 100. The top rods 32 and the runner blocks 33 are both arranged above the top plate mechanism. When the top plate mechanism moves upward, the runner blocks 33 are first lifted and then the top rods 32 are lifted. The upper end of the runner blocks 33 is aligned with the connection between the injection channel and the mold cavity. In the present solution, when the injection molding of the middle wind wheel 100 is completed and the mold is opened, the injection molding equipment acts on the top plate mechanism. When the top plate mechanism moves upward, it first drives the plurality of runner blocks 33 upward. The runner blocks 33 move upward to separate the material handle 101 from the wind wheel 100, and then continue to move upward to eject the wind wheel 100 through the top rods 32. In this way, the middle wind wheel mold can separate the material handle 101 from the wind wheel 100 when the mold is opened.

[0021] In the specific embodiment shown in the figure, the ejector mechanism includes an ejector plate 34 and an ejector pin plate assembly, the lower end of the flow channel block 33 abuts against the ejector plate 34, and the lower ends of the ejector pin and ejector shaft 31 pass through the ejector plate 34 and are fixedly connected to the ejector pin plate assembly. When the mold is opened, the ejector plate 34 moves up a certain distance and then drives the ejector pin plate assembly upward. Furthermore, a guide screw 35 is fixedly connected to the lower end of the ejector plate 34, and a guide chamber 360 is constructed in the ejector pin plate assembly. The screw head of the guide screw 35 is movably arranged inside the guide chamber 360, and the ejector plate 34 drives the guide screw 35 upward. At this time, the screw head of the guide screw 35 moves upward in the guide chamber 360 until the screw head abuts against the ejector pin plate assembly, and then the ejector plate 34 and the pin plate assembly move upward synchronously. The ejector plate assembly includes an upper ejector plate 361 and a lower ejector plate 362 , which are combined together, and the lower ends of the ejector pins and ejector shafts 31 are fixed between the upper ejector plate 361 and the lower ejector plate 362 .

[0022] In a further embodiment, the inner edge of the runner block 33 is constructed to be inclined inward from bottom to top relative to the radial direction of the lower mold core 22, so that the runner block 33 is constructed to be wide at the top and narrow at the bottom, and the space on the lower mold core 22 to accommodate the runner block 33 is adapted to its shape. In this scheme, when the runner block 33 moves upward under the action of the top plate 34 and cuts the material handle 101 and the wind wheel 100, since the runner block 33 is constructed into the above shape, the width of the runner block 33 is smaller than the width of the space at the same height in the current state after the runner block 33 moves upward compared with the space for accommodating on the lower mold core 22, so that the runner block 33 can avoid inward in the radial direction, thereby avoiding interference with the runner block 33 when the ejector ejects the wind wheel 100 or causing wear between the runner block 33 and the runner block 33.

[0023] In summary, when the middle wind wheel mold is opened, the injection molding equipment acts on the top plate 34, and the top plate 34 first drives the multiple flow channel blocks 33 upward, and the flow channel blocks 33 move upward to separate the material handle 101 from the wind wheel 100. At the same time, the guide screw 35 fixed to the top plate 34 moves upward, and at this time, the screw head of the guide screw 35 moves upward in the guide chamber 360 until the screw head and the ejector plate assembly are against each other. Then, the top plate 34 continues to move upward to eject the wind wheel 100 through the ejector 32. In this way, the middle wind wheel mold can achieve the separation of the material handle 101 and the wind wheel 100 when the mold is opened.
