Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for producing refrigerator handles. Background Technology

[0002] With the improvement of people's living standards, the market demand for refrigerators, as an essential household appliance, continues to grow. Refrigerator handles, as an important component of refrigerators, not only affect the overall appearance of the refrigerator but also directly impact the user experience. While there are various production methods for refrigerator handles, injection molding has become the mainstream method due to its ability to efficiently and precisely manufacture complex-shaped plastic products at a relatively low cost.

[0003] Currently, the injection molds used for producing refrigerator handles generally use bolt connections to ensure stability during use. When it is necessary to switch to producing other specifications of refrigerator handles, it is necessary to loosen the fixing bolts one by one with disassembly tools. This process takes a long time and has a significant impact on the overall production progress of refrigerator handles. Utility Model Content

[0004] This utility model relates to an injection mold for producing refrigerator handles, which solves the problem that existing injection molds for producing refrigerator handles often use bolts for connection and fixation in order to ensure stability during use. When other specifications of refrigerator handles need to be produced, disassembly and assembly tools are required to loosen the bolts used for fixing, which takes a long time.

[0005] In a first aspect, this utility model provides an injection mold for producing refrigerator handles, specifically comprising: a base, a fixed seat, a movable seat, a screw, a mold frame, a fixed injection mold, a movable injection mold, a movable plate, a tie rod, and a hydraulic cylinder; the fixed seat and the movable seat are mounted on the top of the base, and a screw is connected to the top of the base, the screw being connected to the movable seat; the bottom of the mold frame is connected to the fixed seat and the movable seat, the fixed injection mold is fixedly connected to the guide rod of the mold frame, the movable injection mold and the movable plate are slidably connected to the guide rod of the mold frame, the movable injection mold is in contact with the fixed injection mold, and the injection pipeline is connected to the fixed injection mold; a push rod is provided on the outside of the movable plate, a top hole is provided in the mold groove of the fixed injection mold, and the push rod is slidably connected in the top hole; a tie rod is connected to the outside of the movable injection mold, and the tie rod is connected to the movable plate; a hydraulic cylinder is fixedly mounted on the outside of the mold frame, and the piston rod of the hydraulic cylinder is connected to the movable injection mold.

[0006] Furthermore, the injection mold has a cooling channel inside, which is curved and connected to a circulating cooling pipeline at both ends.

[0007] Furthermore, the movable plate has protrusions on both sides, and the pull rod has movable holes inside, with the protrusions slidably connected within the movable holes.

[0008] Furthermore, a spring is fitted outside the guide rod of the mold frame, with one end of the spring contacting the injection mold and the other end of the spring contacting the movable plate.

[0009] Furthermore, the mold frame is provided with connecting blocks on the outside, the fixed seat is provided with a fixed groove on the top, the connecting block at one end of the mold frame is located in the fixed groove, the movable seat is provided with a movable groove on the top, and the connecting block at the other end of the mold frame is located in the movable groove.

[0010] Furthermore, a guide block is provided at the top of the base, and a sliding hole is provided at the bottom of the moving seat, with the guide block slidably connected within the sliding hole.

[0011] Furthermore, the screw is rotatably connected to the base, and a screw hole is provided on the top of the moving base, with the screw threaded into the screw hole.

[0012] This utility model provides an injection mold for manufacturing refrigerator handles, which has the following advantages:

[0013] When this invention is in use, after the molten plastic is injected into the cavity formed by the fixed injection mold and the moving injection mold, the circulating cooling equipment is started, and cold water is transported to the cooling channel through the circulating cooling pipeline to assist in cooling the injection molded parts in the cavity, thereby shortening the cooling and molding time of the injection molded parts and improving the production efficiency of injection molded parts.

[0014] Furthermore, after the moving mold and the fixed mold separate, the protrusion gradually moves to one end of the movable hole. The moving mold moves the movable plate through the tie rod, and the spring gradually contracts, ejecting the injection part located in the fixed mold through the ejector rod. During the inward movement of the moving mold, the movable plate is reset under the influence of the spring force, causing the end of the ejector rod to fully retract to the top hole. The protrusion gradually moves to the other end of the movable hole, and the moving mold and the fixed mold are in a merged state, at which point the refrigerator handle injection molding operation can be performed.

[0015] In addition, after the connecting block at one end of the mold frame is connected to the fixed groove, rotating the screw will cause the moving seat to move inward, so that the connecting block at the other end of the mold frame is connected to the moving groove, thus fixing the mold frame. When it is necessary to replace it according to the different specifications of the refrigerator handle, rotating the screw in the opposite direction will cause the moving seat to move outward, and the connecting block will separate from the moving groove, so that the mold frame can be disassembled from the top of the fixed seat and the moving seat, making replacement simpler and faster.

The ejector rod 801 is slidably connected to the top hole 601; the external connection of the injection moving mold 7 is a tie rod 10, which is connected to the movable plate 8; the external fixed installation of the mold frame 5 is a hydraulic cylinder 11, and the piston rod of the hydraulic cylinder 11 is connected to the injection moving mold 7; the internal installation of the injection moving mold 7 is a cooling channel 701, which is curved and connected to the circulating cooling pipes at both ends; when the molten plastic is injected into the cavity formed by the injection fixed mold 6 and the injection moving mold 7, the circulating cooling equipment is started, and cold water is transported to the cooling channel 701 through the circulating cooling pipes to assist in cooling the injection part in the cavity, shorten the cooling and molding time of the injection part, and improve the production efficiency of the injection part.

[0030] In this embodiment of the utility model, protrusions 802 are provided on both sides of the movable plate 8, and movable holes 1001 are provided inside the pull rod 10. The protrusions 802 are slidably connected in the movable holes 1001. A spring 9 is fitted on the outside of the guide rod of the mold frame 5. One end of the spring 9 is in contact with the injection mold 6, and the other end of the spring 9 is in contact with the movable plate 8.

[0031] Using the above technical solution, after the injection molding moving mold 7 and the injection molding fixed mold 6 are separated, the protrusion 802 gradually moves to one end of the movable hole 1001. The injection molding moving mold 7 drives the movable plate 8 to move through the pull rod 10, and the spring 9 gradually contracts. The ejector rod 801 ejects the injection molded part located in the injection molding fixed mold 6.

[0034] The working principle of this embodiment is as follows: The hydraulic cylinder 11 drives the injection mold 7 to move. During the inward movement of the injection mold 7, the movable plate 8 is reset under the influence of the spring 9, causing the end of the ejector rod 801 to fully retract to the top hole 601. The protrusion 802 gradually moves to the other end of the movable hole 1001, and the injection mold 7 and the injection mold 6 are in a merged state.
