Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a precision positioning injection mold. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Its advantages include high production speed and efficiency, automated operation, a wide variety of colors and shapes (from simple to complex), and sizes ranging from large to small. It also produces precise dimensions, facilitates product updates, and can create complex-shaped parts. Injection molding is suitable for mass production and molding of complex-shaped products. It involves injecting fully molten plastic material, stirred by a screw at a specific temperature, into a mold cavity under high pressure, and then cooling and solidifying to obtain the molded product. This method is suitable for the mass production of complex-shaped parts and is one of the important processing methods. However, an existing mobile phone case injection mold with a precise positioning mechanism (Announcement No.: CN220784680U) has the following disadvantages in use: During the use of injection molds, the upper and lower molds need to be positioned. Positioning is achieved by sliding a block on the surface of a round rod. However, after repeated use, wear easily occurs between the block and the contact point with the round rod, causing the upper and lower molds to misalign, which in turn affects the quality of the finished product. Therefore, the block and the round rod need to be replaced. However, replacing the existing block and the round rod requires replacing the entire part, which is relatively wasteful of materials. To address this issue, this patent proposes a precision positioning injection mold to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a precision-positioning injection mold to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a precision-positioning injection mold, comprising a base and a mounting base, wherein a lower mold is fixed to the top of the base, an upper mold is fixed to the bottom of the mounting base, a plurality of fixing rods are fixed to the top of the base, a first protective sleeve is detachably installed on the outer wall of the fixing rods, and a plurality of insertion ports corresponding one-to-one with the fixing rods are opened through the top of the mounting base, a second protective sleeve is detachably installed in the insertion ports, and the first protective sleeve is inserted into the second protective sleeve.

[0005] Preferably, a first connecting plate is fixed to the bottom end of the first protective sleeve, a second connecting plate is fixed to the outer wall of the fixing rod, a plurality of first mounting holes are opened on the second connecting plate, a plurality of first screws corresponding one-to-one with the first mounting holes are fixed to the bottom end of the first connecting plate, the first screws are inserted into the first mounting holes, and a first nut is screwed to the outer wall of the first screw.

[0006] Preferably, a third connecting plate is fixed to the top of the second protective sleeve, and a plurality of second mounting holes are opened at the top of the third connecting plate. A plurality of second screws corresponding to the second mounting holes are fixed to the top of the mounting base. The second screws are inserted into the second mounting holes, and a second nut is screwed onto the outer wall of the second screw.

It also produces precise dimensions, facilitates product updates, and can create complex parts. Injection molding is suitable for mass production and molding of complex-shaped products. It involves injecting fully molten plastic material, stirred by a screw at a specific temperature, into a mold cavity under high pressure, and then cooling and solidifying to obtain the molded product. This method is suitable for the mass production of complex parts and is one of the important processing methods.

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: a precision-positioning injection mold, including a base 1 and a mounting base 2. A lower mold 3 is fixed to the top of the base 1, and an upper mold 4 is fixed to the bottom of the mounting base 2. A plurality of fixing rods 5 are fixed to the top of the base 1. A first protective sleeve 6 is detachably installed on the outer wall of the fixing rod 5. A plurality of insertion ports 11 corresponding one-to-one with the fixing rods 5 are opened through the top of the mounting base 2. A second protective sleeve 12 is detachably installed in the insertion ports 11. The first protective sleeve 6 is inserted into the second protective sleeve 12.

[0016] It should be noted that by fitting a first protective sleeve 6 on the outer wall of the fixed rod 5 to protect the fixed rod 5, and installing a second protective sleeve 12 in the insertion port 11 inside the mounting base 2, the first protective sleeve 6 and the second protective sleeve 12 are slidably connected to achieve the positioning of the injection mold. When the first protective sleeve 6 and the second protective sleeve 12 are worn and affect the positioning, the worn first protective sleeve 6 and the second protective sleeve 12 can be removed without replacing the entire device, saving a lot of materials and avoiding waste of resources.

[0017] like Figure 3 As shown, a first connecting plate 7 is fixed to the bottom end of the first protective sleeve 6, and a second connecting plate 8 is fixed to the outer wall of the fixing rod 5. The second connecting plate 8 has multiple first mounting holes 9. A multiple first screws 10 corresponding to the first mounting holes 9 are fixed to the bottom end of the first connecting plate 7. The first screws 10 are inserted into the first mounting holes 9, and a first nut is screwed onto the outer wall of the first screws 10.

[0018] It should be noted that when the first protective sleeve 6 is worn and needs to be replaced, it is easy to remove by simply removing the first nut from the bottom of the first screw 10 and then pulling the first protective sleeve 6 out of the fixing rod 5.

[0019] like Figure 4 As shown, a third connecting plate 13 is fixed to the top of the second protective sleeve 12. The top of the third connecting plate 13 has multiple second mounting ports 14.
