Description

Technical Field

[0001] The utility model relates to the technical field of molding devices, in particular to a blower shell molding device. Background Art

[0002] Moulds are various moulds and tools used in industrial production for injection moulding, blow moulding, extrusion, die casting or forging, smelting, stamping and other methods to obtain the required products. In short, moulds are tools used to make moulded objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the moulded material. It is known as the "mother of industry". It is a tool that makes the blank become a part of a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, as well as compression or injection molding of engineering plastics, rubber, ceramics and other products.

[0003] The Chinese patent with the authorization announcement number CN215825818U discloses a blower housing injection molding mold, which relates to the field of mold technology, specifically a blower housing injection molding mold, including a movable mold, a core pulling block is fixedly installed in the middle of the back of the movable mold, a driving groove is opened on the left side of the upper surface of the movable mold, and an inclined top column is movably sleeved in the driving groove opened on the left side of the upper surface of the movable mold, and the inclined top column is installed at an angle of thirty degrees. The blower housing injection molding mold can make the movable mold and the fixed mold close by pushing the ejector rod, and the inclined top column can be moved by starting the travel switch, thereby driving the drive block, so that the composite core pulling block shapes the air outlet of the blower. The lateral core pulling mechanism combining the composite core pulling and the delayed core pulling can make the model molding more convenient. The mold formed by the device is one-fourth of the blower, and the blower housing can be molded by splicing, which greatly improves the practicality of the device.

[0004] However, in the implementation of relevant technologies, it was found that the design of the injection molding mold for the above-mentioned blower housing has the following problems: the first limit block and the second limit block should have the function of stabilizing the position of the movable mold and the fixed mold to ensure that they can be accurately aligned and closed. However, these two limit blocks cannot effectively limit the shaking of the mold, which may cause a slight positional offset between the movable mold and the fixed mold when the mold is closed. Although this offset may seem small, it is enough to affect the closing accuracy of the mold, thereby causing the risk of mold closing failure. Utility Model Content

[0026] Referring to Figures 1 - 3 , for an embodiment of the present utility model, a blower housing forming device is provided, including a main body unit 100, a forming unit 200 and a limiting unit 300;

[0027] Among them, the main body unit 100 includes a moving mold 101 and a fixed mold 102 that is installed to match the moving mold 101. A first core-pulling block 104 is fixedly installed on one side of the moving mold 101 close to the fixed mold 102. A pull rod 103 is fixedly installed on the side of the moving mold 101 away from the fixed mold 102. A plastic molding groove 105 is provided on one side of the fixed mold 102 close to the first core-pulling block 104, and the plastic molding groove 105 is slidably connected to the first core-pulling block 104. An injection molding pipe 106 is fixedly installed on one side of the fixed mold 102, and the injection molding pipe 106 communicates with the plastic molding groove 105. When in use, first, the pull rod 103 needs to be pushed to make the moving mold 101 and the fixed mold 102 close the mold, and then injection molding is carried out using the fixed mold 102 to form the mold shape;

[0028] The limiting unit 300 includes mounting blocks 301 fixedly installed on both sides of the moving mold 101. A slot 303 is provided on one side of the mounting block 301. Plug blocks 302 are symmetrically installed on both sides of the fixed mold 102, and the plug blocks 302 are slidably connected to the slot 303. A clamping groove 313 is provided at the top of the plug block 302. A fixing block 306 is fixedly installed at the top of the mounting block 301. A second telescopic spring 307 is fixedly installed in the inner cavity of the fixing block 306. A limiting plate 308 is fixedly installed at the bottom end of the second telescopic spring 307. A limiting block 309 is fixedly installed at the bottom end of the limiting plate 308, and the limiting block 309 is clamped with the clamping groove 313. A through hole 312 is provided at the top of the mounting block 301, and the through hole 312 is slidably connected to the limiting block 309. First, the limiting plate 308 is slid upward. When the limiting plate 308 moves, it will drive the limiting block 309 to move upward until the limiting block 309 moves into the inner cavity of the fixing block 306. During the movement of the limiting plate 308, the second telescopic spring 307 will be compressed. During the process of the moving mold 101 and the fixed mold 102 closing the mold, the plug block 302 will be inserted into the inner cavity of the slot 303. Canceling the sliding of the limiting plate 308, the elastic force of the compression of the second telescopic spring 307 is released to pop the limiting block 309 downward, so that the limiting block 309 is inserted into the clamping groove 313 opened by the plug block 302, completing the limiting of the moving mold 101 and avoiding deviation during mold closing, thereby preventing the occurrence of mold closing failure.

[0029] A second sliding groove 310 is provided on one side of the fixing block 306. A handle 311 is slidably connected to the inner cavity of the second sliding groove 310, and one side of the handle 311 close to the fixing block 306 is fixedly connected to the through hole 312. The through hole 312 is driven to slide by the handle 311.

[0030] A first telescopic spring 304 is fixedly installed in the inner cavity of the installation block 301. One end of the first telescopic spring 304 close to the insertion block 302 is fixedly installed with a pressing plate 305, and the side of the pressing plate 305 away from the first telescopic spring 304 is in close contact with one end of the insertion block 302. When the insertion block 302 is inserted into the inner cavity of the installation block 301, the pressing plate 305 will be squeezed. Under the extrusion of the first telescopic spring 304, the stability of the movable mold 101 after being fixed will be improved, and the movable mold 101 will be reset by the elastic force.

[0031] The molding unit 200 includes a moving groove 205 opened at the top end of the fixed mold 102. A driving block 204 is slidably connected in the inner cavity of the moving groove 205. One side of the driving block 204 is fixedly installed with a sliding block 206. A first sliding groove 207 is opened on one side of the moving groove 205, and the first sliding groove 207 and the sliding block 206 are slidably connected. The driving block 204 slides in the moving groove 205, thereby driving the composite core-pulling block 208 to move towards the plastic molding groove 105, so that the composite core-pulling block 208 is in the mold cavity, thereby forming the air outlet of the blower.

[0032] An activity groove 209 is opened on the opposite surface of the moving groove 205 and the plastic molding groove 105. One side of the driving block 204 close to the first core-pulling block 104 is fixedly installed with a composite core-pulling block 208, and the composite core-pulling block 208 is slidably connected with the activity groove 209. The composite core-pulling block 208 is arc-shaped, and the sliding block 206 moves along with the driving block 204 to ensure the stability of the driving block 204 during movement.

[0033] One side of the fixed mold 102 is fixedly installed with a connecting seat 201. The top end of the connecting seat 201 is fixedly installed with an electric telescopic rod 202. The output end of the electric telescopic rod 202 is fixedly installed with a connecting block 203, and the bottom end of the connecting block 203 is fixedly connected with the driving block 204. The movement of the driving block 204 is realized through the electric telescopic rod 202.

[0034] During the use process, when in use, first slide the limit plate 308 upward. When the limit plate 308 moves, it will drive the limit block 309 to move upward until the limit block 309 moves into the inner cavity of the fixed block 306. During the movement of the limit plate 308, it will squeeze the second telescopic spring 307 and push the pull rod 103, causing the moving die 101 to be combined with the fixed die 102. During the movement of the limit plate 308, it will squeeze the second telescopic spring 307. During the process of the moving die 101 and the fixed die 102 being combined, the insertion block 302 will be inserted into the inner cavity of the insertion slot 303, canceling the sliding of the limit plate 308. The elastic force squeezed by the second telescopic spring 307 is released to pop the limit block 309 downward, so that the limit block 309 is inserted into the card slot 313 opened by the insertion block 302, completing the limit of the moving die 101. When the insertion block 302 is inserted into the inner cavity of the mounting block 301, it will squeeze the extrusion plate 305. Under the extrusion of the first telescopic spring 304, the stability after the moving die 101 is fixed will be improved, and the moving die 101 will also be reset by the elastic force to avoid deviation during the combination of the dies, thus causing the situation of combination failure. Then, injection molding is carried out using the fixed die 102 to form the mold shape. The movement of the driving block 204 is realized through the electric telescopic rod 202, thereby driving the driving block 204 to move in the direction of the plastic molding groove 105, so that the composite core pulling block 208 is in the mold cavity, thereby forming the air outlet of the blower. When the injection molding is completed, pull the pull rod 103 to separate the moving die 101 from the fixed die 102.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
