Description
Technical Field
[0001] The utility model relates to the technical field of connector injection molding, in particular to an injection molding structure for special-shaped connectors. Background Art
[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors and patterns, shapes from simple to complex, sizes from large to small, and precise product sizes. The products are easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. Existing injection molding molds mostly use a method of extruding and sealing the mold cavity and then injecting into the mold cavity for processing. However, the extrusion method of existing injection molding molds often uses sealing based on the gravity of the top plate itself. When injecting into the mold cavity, due to the high pressure inside the mold cavity, the top plate and the mold base are often not tightened. These conditions may cause raw materials to overflow or bubbles to form inside during injection molding, resulting in product production failure.
[0003] Among them, announcement number "CN208759960U" discloses "a plastic part injection molding device". This injection molding device provides a water inlet pipe, a U-shaped pipe, a cooling fan and other components from the aspect of cooling the mold base, and the idea of circulating and assisting the heat dissipation of the mold base, which has high practicality. However, this injection molding device still has certain shortcomings in actual use. Although this injection molding device focuses on strengthening the heat dissipation of the device, it still adopts the traditional method of relying on the gravity of the top plate to extrude and fix the mold cavity during product injection molding, which easily causes the device to be unstable during product processing. In addition, it still uses an integrated mold. When it is necessary to produce other types of products, the entire device needs to be replaced, which greatly increases the use cost of the device. For this reason, the utility model provides an injection molding structure for special-shaped connectors. Utility Model Content
[0004] In view of the deficiencies of the prior art, the utility model provides an injection molding structure for special-shaped connectors, which solves the problems of loose fastening between the mold base and the top plate during injection molding, difficulty in processing a variety of products due to the integrated mold, and inconvenience in replacing the mold.
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: an injection molding structure for a special-shaped connector, including a mold base and a top plate, two fixing blocks are fixedly installed on opposite sides of the top plate, a fixing hole is penetrated through one side of the fixing block, a placement cavity is opened on the inner side of the mold base, a fastening unit for fastening the mold base and the top plate is fixedly installed at the top of the outer side of the mold base corresponding to the fixing block, the fastening unit includes a fixing seat installed at the top of the outer side of the mold base corresponding to the fixing block, a sliding hole for sliding connection of a fixing column is longitudinally opened on the fixing seat, a limiting ring hole is opened at one end of the sliding hole, a card groove for connecting the fixing block is opened at the longitudinal center of the fixing seat, and two limit blocks for sliding card connection are fixedly connected to one end of the outer side of the fixing column.
[0006] Preferably, an injection molding device for product injection molding is fixedly installed on the top of the top plate, and a plurality of injection molding tubes are fixedly installed on the bottom of the top plate.
[0007] Preferably, a mold is slidably connected to the inner side of the placement cavity, and a plurality of mold cavities are opened inside the mold.
[0008] Preferably, four return springs are fixedly installed at the four corners of the inner bottom of the placement cavity, and a supporting plate is fixedly connected to the top of the return spring.
[0009] Preferably, the sliding hole corresponds to the fixing hole.
[0010] Preferably, the height of the placement cavity is equal to the sum of the mold height, the support plate height and the compressed height of the return spring.
[0011] Beneficial Effects
[0012] The utility model provides an injection molding structure for special-shaped plug connectors. Compared with the prior art, it has the following beneficial effects:
[0013] (1) The injection molding structure for special-shaped connectors can connect the product to the fastening unit through the fixing block on the top plate during injection molding, and then the fixing block is inserted into the slot by screwing and pulling out the fixing column. The fixing column is then pushed to pass through the fixing seat and the fixing hole to fix the fixing block in the slot, and the limiting block is screwed into the limiting ring hole by screwing the fixing column to complete the locking of the fixing column, thereby ensuring the fixed locking between the top plate and the mold base, and greatly reducing the risk of the product being loosely fixed between the top plate and the mold base during injection molding.
[0014] (2) The injection molding structure for special-shaped connectors can, through the reset spring and the support plate, enable the mold to be partially pushed out by the reset spring when the mold is placed in the placement cavity. When the top plate is pressed down, the mold is completely retracted downward into the placement cavity through the support plate and the reset spring. When the top plate is opened, the mold will be partially pushed out of the placement cavity under the action of the reset spring, so that the mold can be replaced when producing products of other specifications, which greatly reduces the use cost of the injection molding device.
