Description

Technical Field

[0001] This utility model relates to the field of mold equipment technology, specifically to a mold that facilitates the removal of objects. Background Technology

[0002] Mold equipment refers to tools that process raw materials into products of desired shapes through a specific structure. It usually consists of moving molds and fixed molds and can be used for molding processes such as injection molding, stamping, and die casting. Its core function is to give materials a specific geometric shape through the cavity structure. After the molding process is completed, the solidified or formed mold needs to be separated from the mold cavity by a demolding mechanism to complete the molding process of the mold.

[0003] Existing technologies often have the following problems when used:

[0004] After being molded, the molded parts usually need to undergo natural or active cooling to ensure stable molding. However, the molds used in the molding process are usually thick and difficult to separate. Both natural and active cooling require high time or energy costs, resulting in low efficiency in demolding. Furthermore, after cooling and molding, the molded parts tend to stick to the inner wall of the mold, which creates resistance during removal and affects the smoothness of the removal process. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a convenient mold for removing objects, which can effectively solve the problems that the natural cooling or active cooling of the mold requires high time and energy costs, resulting in low efficiency of mold removal, and that the mold is prone to sticking to the inner wall of the mold after cooling and forming, affecting the continuity and stability of mold removal.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a mold for easily removing objects, including:

[0008] The base has a support frame and a lower mold base fixedly connected to its upper end face. The lower mold base has a hollow structure and a mold inner frame is slidably connected to its inner side.

[0009] A mold assembly / disassembly assembly includes an electric push rod fixedly installed at the top of a support frame. An adapter frame is fixedly connected to the output end of the electric push rod. An upper mold is fixedly connected to the lower end face of the adapter frame. Two opposing sidewalls of the adapter frame are rotatably connected to translation screws with opposite thread directions. Guide blocks are threaded onto both translation screws. Insertion plates are fixedly connected to the lower end faces of both guide blocks. Insertion holes are provided on both insertion plates. Two fixed shafts are fixedly connected to the upper part of the outer wall of the inner mold frame, and these fixed shafts match the insertion holes.

[0010] An auxiliary mold-taking component is rotatably connected through the side wall of the lower mold base.

[0011] Furthermore, the mold assembly and disassembly assembly also includes a small dual-axis motor fixedly installed inside the adapter frame, with the two output ends of the small dual-axis motor respectively fixedly connected to the ends of two translation screws.

[0012] Furthermore, the two opposing outer walls of the adapter frame are fixedly connected to limit plates, and the guide block slides in contact with the limit plates.

[0013] Furthermore, a through groove is provided at the top of the lower mold base, the inner diameter of the through groove is larger than the outer diameter of the plug-in plate, and the thickness of the inner frame of the mold is smaller than that of the lower mold base.

[0014] Furthermore, the auxiliary mold-taking assembly includes a support shaft that is rotatably connected to the lower side wall of the lower mold base. A rotary motor is fixedly installed on the outer wall of the lower mold base. The output end of the rotary motor is fixedly connected to the end of the support shaft. An eccentric wheel is fixedly connected to the outer peripheral wall of the support shaft. A lifting plate is slidably connected to the inner wall of the lower mold base. Several tension springs are fixedly connected between the lifting plate and the base.

[0015] Furthermore, the outer peripheral wall of the eccentric wheel is pressed against the lower end face of the lifting plate, and a strip slide rail is fixedly connected to the lower end face of the lifting plate, with the eccentric wheel located inside the strip slide rail.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention includes a mold assembly and disassembly component. By driving two plug-in plates to move in opposite directions, the plug holes on the two plug-in plates correspond to two fixed shafts, thus completing the connection and fixation between the upper mold and the inner mold frame. Then, by controlling an electric push rod, the upper mold and the inner mold frame are moved upward as a whole, allowing the inner mold frame and the mold part to be separated from the lower mold base. Since the thickness of the inner mold frame is smaller than that of the lower mold base, the time or energy consumption required for the mold part to cool and form can be reduced, making it easier to remove the mold part quickly and effectively improving the overall efficiency of mold part demolding and removal.

[0018] This invention includes an auxiliary mold-removing component. By driving an eccentric wheel to rotate rapidly, the eccentric wheel pushes the lifting plate upward, and several tension springs pull the lifting plate downward to reset it. This allows the lifting plate to perform high-frequency reciprocating lifting motion and strike the bottom of the mold inner frame. The high-frequency vibration causes the mold part to detach from the upper mold and the mold inner frame, effectively preventing the mold part from sticking to the upper mold and the mold inner frame, and ensuring smooth mold part removal.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 4 A mold for easy removal of objects includes: a base 1 and a mold assembly / disassembly assembly 5. A support frame 2 and a lower mold base 3 are fixedly connected to the upper surface of the base 1. The lower mold base 3 has a hollow structure, and a mold inner frame 4 is slidably connected to the inner side of the lower mold base 3. The mold assembly / disassembly assembly 5 includes an electric push rod 51 fixedly installed at the top of the support frame 2. An adapter frame 52 is fixedly connected to the output end of the electric push rod 51. An upper mold 53 is fixedly connected to the lower surface of the adapter frame 52. Translation screws 54 are rotatably connected to both opposing sidewalls of the adapter frame 52. The threads on the two translation screws 54 have opposite directions, and guide blocks 55 are threaded onto both translation screws 54. Limiting plates 7 are fixedly connected to the outer wall. Guide blocks 55 slide in contact with limiting plates 7. Insertion plates 56 are fixedly connected to the lower end faces of the two guide blocks 55. A through groove 8 is opened at the top of the lower mold base 3. The inner diameter of the through groove 8 is larger than the outer diameter of the insertion plate 56, and the thickness of the inner frame 4 of the mold is smaller than that of the lower mold base 3. Insertion holes 57 are opened on the two insertion plates 56. Two fixed shafts 58 are fixedly connected to the upper position of the outer wall of the inner frame 4 of the mold. The fixed shafts 58 match the insertion holes 57. The mold assembly and disassembly assembly 5 also includes a small dual-axis motor 59 fixedly installed inside the adapter frame 52. The two output ends of the small dual-axis motor 59 are fixedly connected to the ends of two translation screws 54 respectively.

[0028] By driving the two plug-in plates 56 to move towards each other, the plug holes 57 on the two plug-in plates 56 correspond to the two fixed shafts 58 respectively, completing the connection and fixation between the upper mold 53 and the inner frame 4 of the mold. Then, by controlling the electric push rod 51, the upper mold 53 and the inner frame 4 of the mold are moved upward as a whole, so that the inner frame 4 of the mold and the mold part can be separated from the lower mold base 3. The thickness of the inner frame 4 of the mold is smaller than that of the lower mold base 3, which can reduce the time or energy consumption cost required for the mold part to cool and form, so as to facilitate the quick removal of the mold part and effectively improve the overall efficiency of mold part demolding and removal.

[0029] Specifically, a cover plate is fixed to the top of the upper mold 53, and the upper mold 53, the cover plate and the inner frame of the mold 4 can form a mold cavity.

[0030] An auxiliary mold-removing component 6 is rotatably connected through the side wall of the lower mold base 3. The auxiliary mold-removing component 6 includes a support shaft 61 rotatably connected through the lower part of the side wall of the lower mold base 3. A rotary motor 62 is fixedly installed on the outer wall of the lower mold base 3. The output end of the rotary motor 62 is fixedly connected to the end of the support shaft 61. An eccentric wheel 63 is fixedly connected to the outer peripheral wall of the support shaft 61. A lifting plate 64 is slidably connected to the inner wall of the lower mold base 3. The outer peripheral wall of the eccentric wheel 63 is pressed against the lower end face of the lifting plate 64. A strip slide rail 9 is fixedly connected to the lower end face of the lifting plate 64. The eccentric wheel 63 is located inside the strip slide rail 9. Several tension springs 65 are fixedly connected between the lifting plate 64 and the base 1.

[0031] The support shaft 61 is driven to rotate rapidly by the rotary motor 62, which in turn causes the eccentric wheel 63 to rotate rapidly and push the lifting plate 64 upward. Several tension springs 65 are used to pull the lifting plate 64 downward to reset it. This allows the lifting plate 64 to perform high-frequency reciprocating lifting and lowering motion and tap the bottom of the inner mold frame 4. This causes the mold part to detach from the upper mold 53 and the inner mold frame 4 due to high-frequency vibration, which can effectively prevent the mold part from sticking to the upper mold 53 and the inner mold frame 4 and ensure the smooth removal of the mold part.

[0032] The working principle of this utility model is as follows:

[0033] When using a mold to press the molded part, the molten molded part material is first fed into the inner frame 4 of the mold. The upper mold 53 is driven to move downward by controlling the electric push rod 51, so that the upper mold 53 gradually enters the inner frame 4 of the mold and extrudes the molded part material. After the molded part is extruded, the small dual-axis motor 59 can be started. The small dual-axis motor 59 drives the two translation screws 54 to rotate synchronously, so that the two guide blocks 55 move towards each other synchronously, and drive the two plug plates 56 to move towards each other, so that the plug holes 57 on the two plug plates 56 correspond to the two fixed shafts 58 respectively, completing the connection and fixation between the upper mold 53 and the inner frame 4 of the mold. Then, the upper mold 53 and the inner frame 4 of the mold are moved upward by controlling the electric push rod 51, so that the inner frame 4 of the mold and the molded part can be separated from the lower mold base 3. The thickness of the inner frame 4 of the mold is smaller than that of the lower mold base 3, so as to reduce the time or energy cost required for the molded part to cool and form.

[0034] After the mold part has cooled down, the upper mold 53, the mold part, and the inner frame 4 can be moved down as a whole by controlling the electric push rod 51, so that the inner frame 4 is in the lower mold base 3. At this time, the rotary motor 62 can be started, and the support shaft 61 can be driven to rotate rapidly by the rotary motor 62, so that the eccentric wheel 63 can rotate rapidly and push the lifting plate 64 to move up. When the lifting plate 64 moves up, several tension springs 65 are in a stretched state and have tension elasticity to pull the lifting plate 64 down to reset, so that the lifting plate 64 can perform high-frequency reciprocating lifting and lowering motion and knock on the bottom of the inner frame 4, so that the mold part can be separated from the upper mold 53 and the inner frame 4 due to high-frequency vibration. Then, by driving the upper mold 53, the mold part, and the inner frame 4 to move up, the inner frame 4 is separated from the lower mold base 3, and the connection and fixation between the upper mold 53 and the inner frame 4 can be released to remove the mold part.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
