Description

Technical Field

[0001] The utility model relates to the technical field of mold frames, in particular to a mold frame which is easy to replace a mold base. Background Art

[0002] The mold frame is a semi-finished product of the mold, which is composed of various steel plates and matching parts. It can be said to be the skeleton of the entire mold. Since the processing involved in the mold frame and the mold is very different, the mold manufacturer will choose to order the mold frame from the mold frame manufacturer, taking advantage of the production advantages of both parties to improve the overall production quality and efficiency. According to the announcement number: CN208133403U, a mold frame is disclosed, including a forming A plate and a forming B plate, the top of the forming A plate is provided with a material channel opening, the bottom of the forming A plate is provided with a first upper mold forming groove and a second upper mold forming groove, the forming A plate is provided with a material channel, a first cooling water channel, and a second cooling water channel, the first upper mold forming groove and the second upper mold forming groove are both connected to the material channel, and the first cooling water channel and the second cooling water channel are arranged around the first upper mold forming groove and the second upper mold forming groove respectively. The utility model has a simple structure and reasonable design, and the development cost of the mold frame is low. Multiple cooling water channels are arranged in the mold frame, and the layout of the multiple cooling water channels is simple and reasonable. However, the above technology still has some defects. For example, since most molds in the existing mold frame are directly fixed on the mold frame, if the mold is damaged and needs to be replaced after long-term use, it will cause inconvenience in using the mold. The practicability is poor and needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: a mold frame which is easy to replace a mold base, comprising a bottom plate, side plates are installed on the sides of the bottom plate, a mounting block A is installed on the top of the bottom plate, a lower mold is arranged inside the mounting block A, support rods are installed at the four corners of the top of the bottom plate, a top plate is installed on the top of the support rod, a hydraulic cylinder is installed on the top of the top plate, a sliding plate is installed on the output end of the hydraulic cylinder, a mounting block B is installed on the bottom end of the sliding plate, a fixed block is installed on the surface of the mounting block B, a clamping rod is arranged inside the fixed block, a turning handle is installed on the surface of the clamping rod, a convex block is installed on the surface of the turning handle, an upper mold is arranged inside the mounting block B, and a pressing block is installed on the bottom end of the upper mold.

[0005] Preferably, a fixing groove is provided at the top of the side plate, the lower die is installed inside the mounting block A through the mounting groove A, and a processing groove is provided at the top of the lower die. Here, it is more convenient for the lower die to slide.

[0006] Preferably, the sliding plate slides on the surface of the support rod through the sliding grooves, and the sliding grooves are evenly distributed at the top four corners of the sliding plate. Here, it is more convenient for the sliding plate to slide.

[0007] Preferably, the clamping rod slides inside the fixed block through the slide groove A, a thread groove is provided on the right side of the clamping rod, the clamping rod slides inside the upper mold through the slide groove B, and the thread groove rotates inside the mounting block B through the rotation groove. Here, it is more convenient for the clamping rod to slide.

[0008] Preferably, a groove is provided on the surface of the protrusion, and the upper mold slides inside the mounting block B through the mounting groove B. The left and right ends of the surface of the upper mold are provided with sliding grooves B. Here, it is more convenient for the upper mold to slide.

[0009] Preferably, a card slot is provided inside the side plate, a card pad is provided inside the card slot, a connecting plate is fixedly installed on the back of the card pad, and a protective cover is fixedly installed on the top of the connecting plate. Here, the fixing bolts are better protected.

[0010] Preferably, the card pad is slidably connected to the fixing groove, the card pad is slidably connected to the side plate, the connecting plate is slidably connected to the side plate, and the protective cover is slidably connected to the side plate. Here, it is more convenient for the card pad and the connecting plate to slide.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. The utility model achieves a better use effect by arranging the mounting block A, the mounting groove A, the mounting block B, the fixing block, the slide groove A, the mounting groove B, the rotating groove, the clamping rod, the threaded groove, the turning handle, the protrusion, the groove, the upper mold and the slide groove B. After a long period of use, when it is necessary to replace it, first pinch the turning handle to rotate it, or use a tool to rotate it through the protrusion and the groove, so that the clamping rod rotates backward inside the rotating groove through the threaded groove. When the threaded groove is completely rotated out of the rotating groove, it can be taken out from the inside of the mounting block B and the upper mold through the slide groove A and the slide groove B. At this time, pinch the upper mold and pull it downward, so that the upper mold can be taken out from the inside of the mounting block B through the mounting groove B and can be replaced, thereby avoiding the existing mold frame because most of the molds are directly fixed on the mold frame. When the mold is damaged and needs to be replaced after a long period of use, it will cause inconvenience in using the mold.

[0013] 2. The utility model provides a card slot, a card pad, a connecting plate and a protective cover to better protect the fixing bolts. When the bottom plate is firmly fixed, the protective cover can be pinched to match the connecting plate to the top of the upper side plate, and then pressed downward to make the connecting plate drive the card pad to slide downward on the top of the side plate through the fixing slot. When the bottom end of the connecting plate contacts the inner wall of the side plate and the card pad slides into the inside of the card slot, the card pad can firmly clamp the protective cover on the top of the side plate through the connecting plate, thereby preventing the fixing bolts from rusting and aging due to rain after long-term use.
