Description

Technical Field

[0001] This utility model relates to the technical field of injection molding sprue head removal devices, and more specifically, to a device for removing sprue heads. Background Technology

[0002] Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and molten material into a mold cavity, which is then cooled and solidified to obtain a molded product. Currently, after injection molding plastic wrapping for chip modules, injection sprue heads remain on the wrapping. At present, the removal of injection sprue heads is done manually, that is, workers need to use hand-held cutting tools to cut off the injection sprue heads. This not only has the disadvantages of high labor intensity for workers, but also low efficiency and low precision in removing injection sprue heads. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for removing sprue heads from injection molding, which can achieve the cutting off of sprue heads from injection molding in a mechanized manner, which can not only reduce the labor intensity of workers, but also improve the cutting efficiency and cutting accuracy of sprue heads from injection molding.

[0004] This utility model provides a device for removing sprue residue, including a frame, a movable base, a drive component, and a support mold base. The support mold base is fixed to the inner bottom of the frame and is used to support the chip module. The movable base is located above the support mold base and is vertically slidably connected to the inner side wall of the frame. The drive component is fixed to the upper end of the frame and is used to drive the movable base to move vertically relative to the frame. The movable base is connected to the drive end of the drive component. A punching block is fixed to the lower end of the movable base. Several punching heads are arranged at intervals from left to right at the lower end of the punching block. A clamping component is connected to the lower end of the movable base located on both sides of the punching block. When the drive component drives the movable base to move downward relative to the frame, each clamping component is used to pre-press the chip module onto the support mold base. As the movable base continues to move downward, each punching head is used to cut off the sprue residue remaining on the chip module.

[0005] By adopting the above-described structure, this invention enables the mechanized removal of injection molding gates, which not only reduces the labor intensity of workers but also improves the efficiency and accuracy of gate removal.

[0006] In one possible implementation, the support base is provided with a cavity corresponding to each chip module, and each chip module is vertically fitted into the cavity at the corresponding position. With this structure, after the chip module is placed on the support base, each chip module can be vertically fitted into the cavity at the corresponding position, thereby achieving the positioning of the chip module and avoiding horizontal displacement of the chip module relative to the support base.

[0007] In one possible implementation, a discharge port is provided in the middle of the support mold base. After the injection sprue head is cut off, the discharge port is used for the injection sprue head to pass vertically through so that it can be discharged from the support mold base. The discharge port is also used to vertically avoid several punching heads. With this structure, after the injection sprue head is cut off, it can pass through the discharge port and be discharged from the support mold base, which facilitates the discharge of the injection sprue head. In addition, when the punching head punches the injection sprue head, the discharge port is used to vertically avoid several punching heads, thereby ensuring that several punching heads punch the injection sprue head and avoiding the situation where the punching heads collide with and damage the support mold base.

[0008] In one possible implementation, each clamping assembly includes a clamping block; each clamping block is vertically slidably connected to the lower end of the moving seat, and an elastic member is provided between each clamping block and the corresponding moving seat. The elastic member is used to apply a spring force to the clamping block to drive it to move downward relative to the moving seat. By using such a clamping assembly, when the driving member drives the moving seat to move downward relative to the frame, the spring force applied by the elastic member to the clamping block can make the clamping block pre-press the chip module onto the support mold base. Thus, when the moving seat continues to move downward and each punching head punches the injection sprue head remaining on the chip module, the chip module can be prevented from shifting relative to the support mold base.

[0009] In one possible implementation, each pressure block has several grooves spaced from left to right at its lower end. When the pressure block moves downward and presses the chip module onto the support mold base, each groove is used to engage with the upper part of the chip module at the corresponding position. With this structure, when the pressure block presses the chip module, each groove can engage with the upper part of the chip module at the corresponding position, thereby further realizing the positioning and limiting of the chip module. This prevents the chip module from shifting when the punching head punches the injection molding sprue head, thus ensuring that the injection molding sprue head is reliably punched and preventing damage to the chip module.

[0010] In one possible implementation, each pressure block has a guide post vertically fixed at the top of both its left and right ends. A guide sleeve corresponding vertically to each guide post is fixed on the movable seat. Each guide post is vertically movably inserted into the guide sleeve at its corresponding position. An end plate is fixed at the upper end of each guide post, and the end plate abuts against the upper end of the guide sleeve to prevent the guide post from vertically detaching from the guide sleeve. With this structure, the pressure block can be reliably vertically slidably connected to the lower end of the movable seat under the cooperation of the guide post and the guide sleeve.

[0011] In one possible implementation, each elastic component includes two springs, each spring being movably sleeved on the outside of two guide posts on the corresponding side. The upper and lower ends of each spring abut against the lower end of the movable seat and the upper end of the pressure block, respectively. By employing such elastic components, the springs can reliably apply a spring force to the pressure block, causing it to move downward relative to the movable seat, so that the pressure block can reliably press the chip module onto the support mold base.

[0012] In one possible implementation, guide rails are vertically fixed on the inner walls of both the left and right sides of the frame, and sliders are fixed at both ends of the movable seat. Each slider is vertically slidably connected to the guide rail on the corresponding side. With this structure, the movable seat can be reliably vertically slidably connected to the frame under the sliding action of the sliders and guide rails.

[0013] In one possible implementation, the driving component is a cylinder, which is vertically fixed to the upper end of the frame, and the piston rod of the cylinder is fixed to the upper end of the movable seat. With this structure, the cylinder can reliably drive the movable seat to slide vertically relative to the frame. In addition, using a cylinder as the driving component has the advantages of simple structure and low cost. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] See Figure 1-5 As shown in the figure, this application discloses a device for removing sprue heads, including a frame 1, a movable base 2, a driving component 3, and a support mold base 4; the support mold base 4 is fixed on the inner bottom of the frame 1 and is used to support the chip module 5; the movable base 2 is located above the support mold base 4 and is vertically slidably connected to the inner sidewall of the frame 1; the driving component 3 is fixed to the upper end of the frame 1 and is used to drive the movable base 2 to move vertically relative to the frame 1; the movable base 2 is connected to the driving end of the driving component 3; the lower end of the movable base 2... A punching block 6 is fixed, and several punching heads 61 are arranged at the lower end of the punching block 6 in a spaced manner from left to right. A clamping component 7 is connected to the lower end of the moving seat 2 located on the front and rear sides of the punching block 6. When the driving component 3 drives the moving seat 2 to move downward relative to the frame 1, each clamping component 7 is used to pre-press the chip module 5 onto the support mold base 4. And when the moving seat 2 continues to move downward, each punching head 61 is used to cut off the injection sprue head 51 remaining on the chip module 5.

[0024] The support base 4 is provided with a cavity 41 corresponding to each chip module 5, and each chip module 5 is vertically fitted into the cavity 41 at the corresponding position. With this structure, after the chip module is placed on the support base, each chip module can be vertically fitted into the cavity at the corresponding position, thereby achieving the positioning of the chip module and avoiding the situation where the chip module is horizontally displaced relative to the support base.

[0025] A discharge port 42 is provided in the middle of the support mold base 4. After the injection sprue head 51 is cut off, the discharge port 42 is used for the injection sprue head 51 to pass vertically through so that the injection sprue head 51 is discharged from the support mold base 4. The discharge port 42 is also used to vertically avoid several punching heads 61. With this structure, after the injection sprue head is cut off, the injection sprue head can pass through the discharge port and be discharged from the support mold base, which can facilitate the discharge of the injection sprue head. In addition, when the punching head punches the injection sprue head, the discharge port is used to vertically avoid several punching heads, thereby ensuring that several punching heads punch the injection sprue head and avoiding the situation where the punching heads collide with and damage the support mold base.

[0026] Each clamping assembly 7 includes a clamping block 71; each clamping block 71 is vertically slidably connected to the lower end of the moving base 2, and an elastic component is provided between each clamping block 71 and the corresponding moving base 2. The elastic component is used to apply a spring force to the clamping block 71 to drive the clamping block 71 to move downward relative to the moving base 2. By adopting this clamping assembly, when the driving member drives the moving base to move downward relative to the frame, under the spring force applied by the elastic component to the clamping block, the clamping block can pre-press the chip module onto the support mold base. Thus, when the moving base continues to move downward and each punching head punches the injection sprue head remaining on the chip module, the chip module can be prevented from shifting relative to the support mold base.

[0027] Each pressure block 71 has several grooves 711 spaced from left to right at its lower end. When the pressure block 71 moves downward and presses the chip module 5 onto the support mold base 4, each groove 711 is used to engage with the upper part of the chip module 5 at the corresponding position. With this structure, when the pressure block presses the chip module, each groove can engage with the upper part of the chip module at the corresponding position, thereby further realizing the positioning and limiting of the chip module. This prevents the chip module from shifting when the punching head punches the injection molding sprue head, thus ensuring that the injection molding sprue head is reliably punched and preventing damage to the chip module.

[0028] Each pressure block 71 has a guide post 72 vertically fixed at the top of both ends. The movable seat 2 has a guide sleeve 73 vertically corresponding to each guide post 72. Each guide post 72 is vertically movably inserted into the guide sleeve 73 at the corresponding position. Each guide post 72 has an end plate 74 fixed at the upper end. The end plate 74 is used to abut against the upper end of the guide sleeve 73 to prevent the guide post 72 from vertically detaching from the guide sleeve 73. With this structure, the pressure block can be reliably vertically slidably connected to the lower end of the movable seat under the cooperation of the guide post and the guide sleeve.

[0029] Each elastic component includes two springs 75, and the two springs 75 in each elastic component are respectively movably sleeved on the outside of the two guide posts 72 on the corresponding side. The upper end and lower end of each spring 75 abut against the lower end of the moving seat 2 and the upper end of the pressure block 71, respectively. By using such elastic components, the springs can reliably apply a spring force to the pressure block to drive the pressure block to move downward relative to the moving seat, so that the pressure block can reliably press the chip module onto the support mold base.

[0030] Guide rails 81 are vertically fixed on the inner walls of both sides of the frame 1, and sliders 82 are fixed on both ends of the movable seat 2. Each slider 82 is vertically slidably connected to the guide rail 81 on the corresponding side. With this structure, the movable seat can be reliably vertically slidably connected to the frame under the sliding action of the slider and the guide rail.

[0031] The driving component 3 is a cylinder, which is vertically fixed to the upper end of the frame 1, and the piston rod of the cylinder is fixed to the upper end of the moving seat 2. With this structure, the cylinder can reliably drive the moving seat to slide vertically relative to the frame. In addition, by using a cylinder as the driving component, it has the advantages of simple structure and low cost.

[0032] When using this invention to cut off the injection sprue head on a chip module, first place the chip module with the remaining injection sprue head on the support mold base and fit the chip module with the support mold base. Then, control the drive component to drive the moving seat to move downward relative to the frame. At this time, each clamping component can pre-press the chip module on the support mold base, and as the moving seat continues to move downward, each punching head can cut off the remaining injection sprue head on the chip module. Then, control the drive component to drive the moving seat to move upward relative to the frame and reset. Finally, remove the chip module with the injection sprue head cut off from the support mold base.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
