Technical Field

[0001] This utility model relates to the field of injection molding robot mold technology, specifically to a quick-change component for injection molding robot molds. Background Technology

[0002] Injection robot molds are molds used to produce robot parts. They are usually made of plastic or rubber materials and have advantages such as high temperature resistance, corrosion resistance, and impact resistance. These molds are finely designed and precise in molding, representing a major technological innovation in the robotics industry.

[0003] In actual production, different robot molds may need to be replaced to produce different types of robots. However, most injection molding robot molds on the market are fixed to the injection molding machine by fixing bolts, which means that specific tools are needed to disassemble and replace the molds, which is time-consuming and labor-intensive. At the same time, the ejection mechanism installed on most molds requires a separate power system to eject the finished product, which increases the cost of use and production. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a quick mold change component for injection molding robots, which has the advantages of convenient mold change, low usage and production costs, and solves the problems mentioned in the background technology.

When installing the upper and lower molds, the springs are compressed and then locked in place by the quick-change mechanism. When it is necessary to change the upper and lower molds, the quick-change mechanism can be removed by removing the handle, and the springs will spring back, pushing the upper and lower molds out of the base mechanism and the sliding mechanism, making it convenient to change the molds.

[0014] 2. The quick mold change component of this injection molding robot uses an ejection mechanism at the bottom of the top cover. When the hydraulic rod extends, the top of the ejection mechanism will fit with the No. 2 through hole on the upper mold. Then, the injection material is injected through the No. 1 and No. 2 feed ports. After the injection is completed, the hydraulic rod will retract and the ejection mechanism will eject the injection molded product, completing the quick demolding. There is no need to install a separate power system, reducing the cost of mold production and use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-8 The injection molding robot mold quick change component includes a base mechanism 1, quick change mechanism 2 threadedly connected to both sides of the base mechanism 1, multiple slide rods 4 fixedly installed on the upper end face of the base mechanism 1, a lower mold mechanism 3 snapped and fixed on the upper end face of the base mechanism 1, a sliding mechanism 5 slidably sleeved on the outer side of the multiple slide rods 4, an upper mold mechanism 9 snapped and fixed on the lower end face of the sliding mechanism 5, a top cover 8 fixedly installed on the upper end face of the multiple slide rods 4, hydraulic rods 6 fixedly installed on both the front and rear sides of the lower end face of the top cover 8, and multiple ejection mechanisms 7 fixedly installed on the middle side of the lower end face of the top cover 8.

[0026] In the above-mentioned mechanism, the lower mold mechanism 3 and the upper mold mechanism 9 are installed and fixed on the base mechanism 1 and the sliding mechanism 5 by the quick change mechanism 2. The lower mold mechanism 3 and the upper mold mechanism 9 can also be quickly changed by the quick change mechanism 2. The slide rod 4 is used to limit the movement direction of the sliding mechanism 5. The hydraulic rod 6 provides power to facilitate injection molding. The ejection mechanism 7 is used to eject the injection molded product from the mold after injection molding is completed, thus completing demolding.

[0027] In a preferred embodiment, the base mechanism 1 includes a base body 101, a plurality of snap-fit ​​holes 102 are provided on the upper end face of the base body 101, a plurality of compression springs 104 are fixedly installed on the upper end face of the base body 101, and screw holes 103 are provided on both sides of the base body 101.

[0028] In the above mechanism, by opening a snap-fit ​​hole 102 at the upper end of the base body 101 and installing a compression spring 104, when the lower mold mechanism 3 is snapped into place through the snap-fit ​​hole 102, the lower mold mechanism 3 will also compress the compression spring 104. Then, the lower mold mechanism 3 is snapped into place on the base mechanism 1 by the quick-change mechanism 2.

[0029] In a preferred embodiment, the quick-change mechanism 2 includes a connecting rod 201, one end of which is fixedly fitted with a handle 202, and the other end of the connecting rod 201 is provided with an external thread 203.

[0030] In the above structure, the connecting rod 201 can be threaded into the base mechanism 1 and the lower mold mechanism 3, and between the sliding mechanism 5 and the upper mold mechanism 9 through the handle 202 to complete the mold installation. The mold can also be quickly disassembled through the handle 202 to facilitate the mold replacement operation.

[0031] In a preferred embodiment, the lower mold mechanism 3 includes a lower mold body 301, with No. 2 screw holes 302 on both sides of the lower mold body 301, and a plurality of snap-fit ​​rods 303 fixedly installed on the lower end face of the lower mold body 301.

[0032] In the above mechanism, the lower mold body 301 is snapped onto the base mechanism 1 by the snap-fit ​​rod 303 for easy positioning, and then installed and fixed onto the base mechanism 1 by the quick-change mechanism 2.

[0033] In a preferred embodiment, the sliding mechanism 5 includes a sliding block 501, a plurality of sliding sleeves 502 are installed through the sliding block 501, a plurality of first through holes 504 are opened on the lower end face of the sliding block 501, a first feed port 506 is opened on the lower end face of the sliding block 501, a plurality of second compression springs 503 are fixedly installed on the lower end face of the sliding block 501, and third screw holes 505 are opened on both sides of the sliding block 501.

[0034] In the above structure, the sliding block 501 is sleeved on the sliding rod 4 through the sliding sleeve 502. The sliding block 501 can slide up and down on the sliding rod 4 through the sliding sleeve 502 to complete the fitting and separation of the upper and lower molds, thereby enabling injection molding and demolding. At the same time, a second compression spring 503 is installed at the lower end of the sliding block 501. When the upper mold mechanism 9 is installed on the sliding block 501, the second compression spring 503 will be compressed. Then, it is locked in place by the quick change mechanism 2. When it is necessary to change the mold, the second compression spring 503 will rebound after the quick change mechanism 2 is disassembled, which will quickly push out the upper mold mechanism 9, making it convenient to change the mold.

[0035] In a preferred embodiment, the ejection mechanism 7 includes an ejection rod 701, and a high-temperature resistant block 702 is fixedly installed on the lower end face of the ejection rod 701.

[0036] In the above mechanism, the ejector rod 701 is installed at the lower end of the top cover 8, which can demold the injection molded product after injection molding. The injection molding raw material usually has a very high temperature, and the high temperature resistant block 702 at the lower end of the ejector rod 701 can protect the ejector rod 701 from the high temperature.

[0037] In a preferred embodiment, the upper mold mechanism 9 includes an upper mold body 901, with four screw holes 902 on both sides of the upper mold body 901, a plurality of second through holes 904 on the lower end face of the upper mold body 901, and a second feed port 903 on the lower end face of the upper mold body 901.

[0038] In the above structure, the ejector mechanism 7 passes through the second through hole 904. When the hydraulic rod 6 of the upper mold mechanism 9 is pressed to the bottom, the ejector mechanism 7 will seal the upper mold body 901, which will facilitate the next step of injection molding.

[0039] Working principle: When installing the upper and lower molds, the lower mold mechanism 3 and the upper mold mechanism 9 will compress the first compression spring 104 and the second compression spring 503 respectively. Then, the quick-change mechanism 2 is threaded into the screw hole to clamp and fix the upper and lower molds on the base mechanism 1 and the sliding mechanism 5, thus completing the mold installation. When it is necessary to change the mold, simply remove the quick-change mechanism 2 through the handle 202. Then the first compression spring 104 and the second compression spring 503 will rebound, thereby quickly ejecting the upper and lower molds. Then repeat the installation steps to complete the mold replacement operation.

[0040] Secondly, by setting an ejection mechanism 7 at the lower end of the top cover 8, when the hydraulic rod 6 extends, the top of the ejection mechanism 7 will fit with the second through hole 904 on the upper mold. Then, the injection molding material is injected through the first feed port 506 and the second feed port 903. After the injection is completed, the hydraulic rod 6 will retract, and the ejection mechanism 7 will eject the injection molded product, completing the rapid demolding. There is no need to install a separate power system, reducing the cost of mold production and use.
