Abstract
Description
Technical Field
[0001] The utility model relates to the field of injection molds, in particular to an injection mold frame which is easy to assemble and disassemble. Background Art
[0002] An injection mold is a tool used to produce plastic products, giving them a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine, and then cooling and solidifying it to obtain a molded product. The injection mold mainly includes upper and lower fixed plates, stripper plates, magnets, mold bases, templates, guide mechanisms, ejection mechanisms, injection systems, and cooling systems. Injection molding can be carried out by fixing the mold to the upper and lower film frames in sequence.
[0003] However, since the current injection molds are usually installed by connecting the plates from bottom to top, when the internal mold needs to be replaced, it needs to be disassembled piece by piece, which is quite troublesome. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention provides an injection mold frame that is easy to assemble and disassemble, thereby solving the problems mentioned in the above background.
[0005] The utility model provides the following technical solutions: a mold frame for an injection mold that is easy to disassemble and assemble, comprising an upper mold frame and a lower mold frame, wherein an upper mold is provided on the lower surface of the upper mold frame, and a lower mold is provided on the upper surface of the lower mold frame at a position corresponding to the upper mold, and the lower mold frame comprises: a first clamping frame and a second clamping frame, wherein the outer side walls of the first clamping frame and the second clamping frame are both provided with mounting sockets, a limit locking rod is installed in the mounting socket on the first clamping frame, a spring is connected between the limit locking rod and the second clamping frame, a limit pin is installed in the mounting socket on the second clamping frame, and a movable frame is provided on the outside of the limit pin and inside the second clamping frame.
[0006] As a further solution of the present invention: a through hole for engaging with the limit pin is provided inside the limit lock rod, and a return spring is installed on the outside of the limit pin and inside the movable frame.
[0007] As a further solution of the present invention: a bottom baffle is provided directly below the lower mold frame, and a guide rod is installed on the upper surface of the bottom baffle passing through the interior of the lower mold frame.
[0008] As a further solution of the present invention: a push plate is installed on the upper surface of the bottom baffle, and a push rod is installed on the upper surface of the push plate.
[0009] As a further solution of the present invention: the upper surfaces of the first clamping frame and the second clamping frame are both provided with limiting grooves for the lower mold to be clamped, and the limiting locking rod is an L-shaped component.
[0010] As a further solution of the present invention: the guide rod is fixedly connected to the bottom baffle by bolts.
[0011] As a further solution of the present invention: an injection molding tube is installed inside the upper mold frame.
[0012] As a further solution of the present invention: the push rod is fixedly connected to the push plate.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] By setting the entire mold frame as an integrated unit except for the upper and lower molds, the rest of the mold frame baffles are set in sections. After the external mold frame baffles are fixed with longitudinal bolts, the upper mold and the lower mold are respectively placed in the corresponding positions of the upper mold frame and the lower mold frame. Therefore, when installation and disassembly are required, it can be achieved by simply adjusting the mold frames on both sides as a whole.
[0015] After the first clamping frame as a whole and the second clamping frame are limited by the limit lock rod inside the mounting socket, by pulling out the limit pin as a whole, the limit pin is pushed toward the hole opened on the limit lock rod under the reset action of the spring sleeved on the outside of the limit pin inside the movable frame, so that disassembly can be achieved without loosening multiple bolts.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] like Figure 1-5 As shown, this embodiment provides an injection mold frame that is easy to disassemble and assemble, including an upper mold frame 1 and a lower mold frame 2. The lower surface of the upper mold frame 1 is provided with an upper mold 4, and the upper surface of the lower mold frame 2 is provided with a lower mold 5 corresponding to the position of the upper mold 4. The lower mold frame 2 includes: a first clamping frame 201 and a second clamping frame 202. The upper surfaces of the first clamping frame 201 and the second clamping frame 202 are both provided with a limiting groove for the lower mold 5 to be clamped. The outer side walls of the first clamping frame 201 and the second clamping frame 202 are both provided with a mounting socket 203, which is located at the first clamping frame. A limit lock rod 205 is installed in the mounting socket 203 on the frame 201. The limit lock rod 205 is an L-shaped component. A spring 204 is connected between the limit lock rod 205 and the second clamping frame 202. A limit pin 206 is installed in the mounting socket 203 on the second clamping frame 202. The outer side of the limit pin 206 is located inside the second clamping frame 202 and a movable frame 207 is provided. A through hole that is engaged with the limit pin 206 is opened inside the limit lock rod 205. The outer side of the limit pin 206 is located inside the movable frame 207 and a return spring is installed.
[0024] like Figure 2-3 As shown, in this embodiment, a bottom baffle 3 is provided directly below the lower mold frame 2, an injection tube 7 is installed inside the upper mold frame 1, a guide rod 6 is installed on the upper surface of the bottom baffle 3 passing through the interior of the lower mold frame 2, the guide rod 6 is fixedly connected to the bottom baffle 3 by bolts, a push plate 8 is installed on the upper surface of the bottom baffle 3, a push rod 9 is installed on the upper surface of the push plate 8, and the push rod 9 is fixedly connected to the push plate 8.
[0025] The working principle of the present invention is as follows: the lower mold frame 2 is divided into a first clamping frame 201 and a second clamping frame 202 as a whole. The bottom baffle 3 and the upper mold frame 1 are composed of the same structure as the lower mold frame 2. After the first clamping frame 201 and the second clamping frame 202 are limited by the limit lock rod 205 inside the installation socket 203, the limit pin 206 is pulled out as a whole. Under the reset action of the spring on the outside of the limit pin 206 inside the movable frame 207, the limit pin 206 is pushed toward the hole opened on the limit lock rod 205, and the limit lock rod 205 inside the first clamping frame 201 is fixed to the second clamping frame 2. 02, the first clamping frame 201 and the second clamping frame 202 are horizontally limited as a whole, and the lower mold 5 is limited as a whole inside the card slot inside the first clamping frame 201 and the second clamping frame 202. After the first clamping frame 201 and the second clamping frame 202 are clamped and fixed, the lower mold 5 is limited. Similarly, the upper mold 4 is installed inside the upper mold frame 1 in the same principle. When the whole needs to be assembled, the installed lower mold frame 2 is placed inside the guide rod 6 above the bottom baffle 3. Therefore, when the upper mold 4 or the lower mold 5 needs to be replaced, it can be quickly realized by loosening the limit pin 206 and the limit lock rod 205.
