Description

Technical Field

[0001] The utility model relates to the technical field of mold frame guide, in particular to a mold frame precision guide mechanism. Background Art

[0002] The mold frame is the support of the mold. In reality, the application of molds involves every product. As long as the product is in large quantity, molds will be used for production, and the mold frame is an inseparable part of the mold.

[0003] However, when the existing mold frame controls the operation of the mold, when the mold frame controls the upper mold plate to be pressed down, it only uses the guide rods installed in the mold frame to assist the upper mold frame to drive the upper mold plate to rise and fall and press down, resulting in poor stability of the upper mold frame during operation, causing deviations when the upper and lower molds are closed, affecting the processing quality of the product. Secondly, when the upper mold frame controls the upper mold plate to be pressed down, the downward pressure is relatively large when the upper and lower molds are closed, which can easily cause damage to the lower mold. In response to the above problems, the inventors proposed a mold frame precision guiding mechanism to solve the above problems. Utility Model Content

[0004] In order to solve the problem that when the mold frame controls the upper mold plate to be pressed down, the upper mold frame is only assisted by the guide rods installed in the mold frame to drive the upper mold plate to be raised, lowered and pressed down, resulting in poor stability of the upper mold frame during operation, causing deviations when the upper and lower molds are closed, affecting the product processing quality; the purpose of the utility model is to provide a mold frame precision guiding mechanism.

[0006] The four guide frames are installed and fixed through the lower mold frame, and the four guide frames assist the upper mold frame to be lifted and lowered.

With the assistance of the buffer spring, the strength of the upper mold in contact with the lower mold when pressed down is reduced. Through the above operation, the strength of the upper mold frame in contact with the lower mold when controlling the upper mold to press down is reduced, which solves the problem that the upper mold is pressed down with a large force when the upper mold and the lower mold are closed, which easily causes damage to the lower mold.

[0021] The four guide frames 2 are installed and fixed by the lower mold frame 1, and the upper mold frame 3 is assisted to be lifted and lowered by the four guide frames 2. When the upper mold frame 3 controls the upper mold to be lifted and lowered, the sliding sleeves 32 installed in the middle of the two sides of the upper mold frame 3 cooperate with the two sliding rods 4 to control the lifting and lowering of the upper mold frame 3, and then the four guide rails 21 installed in one side of the four guide frames 2 cooperate with the four guide sleeves 31 installed on both sides of the upper mold frame 3 to assist the upper mold frame 3 and the upper mold to be lifted and lowered. With the assistance of the four guide rails 21 and the four guide sleeves 31 installed in the four guide frames 2, the stability of the upper mold frame 3 and the upper mold is increased during lifting and lowering, which solves the problem that the upper mold frame is only driven by the guide rods installed in the mold frame to assist the upper mold frame 3 to lift and lower and press down, resulting in poor stability during operation of the upper mold frame, causing deviations when the upper and lower molds are closed, thereby affecting the processing quality of the product.

[0031] By adopting the above technical solution, the upper mold of the mold is installed and fixed through the groove body 6 opened on one side of the upper mold frame 3, and the lower mold of the mold is installed and fixed through the groove body 6 opened on one side of the lower mold frame 1.

[0032] Positioning bars 7 are fixedly installed on both sides of the lower mold frame 1. There are two positioning bars 7. Evenly distributed positioning holes 71 are opened in the two positioning bars 7.

[0035] When the upper mold installed by the upper mold frame 3 is pressed downward, the two lower pressure sleeves 42 installed at the bottom ends of the two sliding sleeves 32 contact with the two upper pressure sleeves 33 sleeved on the surfaces of the two sliding rods 4. With the assistance of the buffer spring 41, the strength of the upper mold in contact with the lower mold when pressed downward is reduced. The above operation reduces the strength of the upper mold in contact with the lower mold when controlled by the upper mold frame 3 when pressed downward.
