Description

Technical Field

[0001] The utility model relates to the technical field of injection molds with replaceable mold cores, in particular to an injection mold assembly with quickly replaceable mold cores. Background Art

[0002] Injection molds are tools used to produce plastic products and give them precise structure and dimensions. Injection molding is a process used for mass production of complex parts. Specifically, the process involves injecting heated, molten plastic into a mold cavity under high pressure using an injection molding machine. After cooling and solidification, the resulting molded product is formed.

[0003] In the prior art, there are injection molds consisting of a mold shell and a mold core. This type of injection mold with a replaceable mold core is convenient for producing different products on an injection molding machine. However, the molds on the injection molding machine are all vertical. Therefore, when disassembling the mold core, one person is required to remove the bolts and one person is required to hold the mold core that is about to fall. When installing a new mold core, two operators are also required to lift the mold core and insert it into the mold. However, due to the small space inside the injection molding machine, the two-person operation affects the replacement efficiency. In order to solve the above problems, we proposed this injection mold assembly with a quickly replaceable mold core. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-4 As shown, an injection mold assembly with a quickly replaceable mold core includes a mold body 1 and a core body 2. A mounting part 3 is provided at the lower end of the mold body 1. A supporting mechanism for supporting the core body 2 is provided in the mounting part 3. The supporting mechanism includes a rotating shaft 4 rotatably connected to the side wall of the mounting part 3. Two rotating parts 8 are fixedly connected to the side wall of the rotating shaft 4. The upper ends of the two rotating parts 8 are commonly fixedly connected to a placement plate 9. A second slot 7 is provided through the side wall of the rotating part 8. A first slot 6 is provided on both side walls of the mounting part 3. An insert rod 5 is commonly provided in the two first slots 6 and the two second slots 7. The mounting part 3 is connected to the mold body 1 through a connecting mechanism.

[0024] The connection mechanism includes two limit bars fixedly connected to the side walls of the mounting member 3. The side walls of the limit bars are provided with slide rails 10. The upper ends of the slide rails 10 are fixedly connected to the lower end of the mold body 1. The side walls of the slide rails 10 are provided with multiple bolts.

[0025] In the present invention, a vertical plate 16 is provided on the side wall of the placement plate 9 to prevent the core body 2 from being pushed excessively on the placement plate 9. The position of the core body 2 needs to be repeatedly adjusted to align it with the mold body 1. Two third slots 11 are provided on the side wall of the mounting part 3. After the rotating part 8 is vertical, it can be inserted and limited by the insertion rod 5 to prevent the rotating part 8 from shaking at will.

[0026] In the present invention, a limiting groove is provided on the side wall of the placement plate 9, and a limiting block 14 is provided in the limiting groove. The limiting block 14 is fixedly connected to the vertical plate 16 so that the vertical plate 16 can be disassembled for easy transportation. The limiting block 14 is made of a magnet.

[0027] In the present invention, a handle 15 is fixedly connected to the side wall of the insertion rod 5 to facilitate gripping the insertion rod 5 , and a non-slip sleeve is provided on the side wall of the handle 15 .

[0028] In the present invention, a baffle 12 is fixedly connected to the lower end of the mounting member 3, and a buffer pad 13 is provided on the side wall of the baffle 12, which can block the rotating member 8 when the placement plate 9 falls back, preventing the rotating member 8 from swinging back and forth too many times.

[0029] In the present invention, the lower end of the mounting member 3 is fixedly connected to a first stop bar 17 , and the lower end of the mounting member 3 is fixedly connected to a second stop bar 18 , which can prevent the insertion rod 5 from being over-inserted.

[0030] It should be noted that the present invention is an injection mold assembly that can quickly replace the mold core. The user removes the bolts on the mold core body 2 and pulls the mold core body 2 out of the mold body 1. During the extraction process, the mold core body 2 will fall on the placement plate 9. As the mold core body 2 is completely pulled out, the mold core body 2 can be pulled out on the placement plate 9 in the front and rear directions, and then a new mold core body 2 is placed on the placement plate 9. After the mold core body 2 is aligned with the mold body 1, the mold core body 2 can be pushed into the mold body 1 on the placement plate 9. There is no need for multiple people to work together to replace the mold core body 2. At the same time, it also avoids the situation where the heavy mold core body 2 falls off after the operator fails to grip it tightly after it is detached from the mold body 1. At the same time, it also provides support for the installation of the mold core body 2, and there is no need for manual support and alignment, which greatly facilitates the replacement of the mold core body 2.

[0031] After the core body 2 is replaced, the insert rod 5 is pulled out from the mounting member 3 and the rotating member 8 so that the mold body 1 can move left and right normally or be closed.
