Description

Technical Field

[0001] This utility model belongs to the field of toy manufacturing technology, specifically an extrusion module for toy manufacturing. Background Technology

[0002] Plastic toys are usually produced by extrusion. In order to improve production efficiency and facilitate mold replacement to produce toys of different shapes, an extrusion module for toy production is proposed.

[0003] Among them, a search revealed an application with application number CN202121529642.2, which discloses an extrusion device for raw materials used in toy car production. The device includes an extruder body, the sides of which are covered with thermally conductive silicone grease, and a heat sink is movably connected to the sides of the extruder body. This enhances heat dissipation, prevents damage to the device due to high temperatures, and allows for easy replacement of the thermally conductive silicone grease, thus avoiding affecting the heat dissipation effect after prolonged use.

[0004] However, research has revealed that the device does not provide a high degree of continuity in the extrusion process of toys, and it lacks a structure for rapidly cooling the extruded toys. It only cools the extruder body, resulting in a low natural cooling rate of the toys, low work efficiency, and inconvenience in changing toy molds to produce toys of different shapes. Therefore, a new type of device is proposed to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to provide an extrusion module for toy production in order to solve the problems of low work efficiency and lack of flexibility in use.

[0006] The technical solution adopted by this utility model is as follows: an extrusion module for toy production includes a support frame, a slide plate is slidably connected above the support frame via a slide rail, a servo electric cylinder A is installed on one side of the support frame, and the end of the servo electric cylinder A is connected to the slide plate, and a hot melt extruder is fixedly installed above the slide plate;

[0007] Above the support frame is an extrusion mechanism that can continuously perform extrusion work, and a cooling mechanism that can quickly cool and shape the toy.

[0008] The extrusion mechanism includes a support plate, a servo motor, mold A, and mold B. A support plate, rotatably connected to the other side of the support frame via the servo motor, is arranged in a disc shape. Mold A is movably connected to one side of the support plate, and mold B is movably connected to one side of mold A. Sealing rubber rings are bonded to the contact areas of mold A and mold B. An injection port, fitting to the hot melt extruder outlet, is located on the back of mold B. Sealing rubber rings are bonded to the inner wall of the injection port and the outer wall of the hot melt extruder outlet. The back of mold A... The mold is fixedly installed with a screw, and the surface of the support plate is provided with a through hole that fits with the screw. The end of the screw is threaded with a limit nut. There are five molds A, and the five molds A are equidistantly installed around one side of the support plate. The molds B are symmetrically fixedly installed with buckles on one side. The buckles are elastically connected with spring blocks on one side. The molds A are embedded with a slot that fits with the buckle. The slot is embedded with a recess that fits with the spring block. The molds A are symmetrically elastically connected with release rods on both sides through through slots. The ends of the release rods extend into the recesses.

[0009] The cooling mechanism includes a water tank, a circulating water pump, a chiller, a cooling cover, and a servo electric cylinder B. The water tank is fixedly installed on the upper part of the support frame corresponding to the support plate. The outlet of the water tank is connected to the circulating water pump. The chiller is fixedly installed below the support frame and is connected to the circulating water pump via a pipe. A cooling cover is installed on one side of the support frame via the servo electric cylinder B. The cooling cover has a cavity inside, and a water outlet hole communicating with the cavity is embedded in the inner wall of the cooling cover. The cooling cover is connected to the chiller via a pipe, and an opening is provided at the bottom of the cooling cover.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] 1. In this utility model, through the extrusion mechanism, the servo motor drives the support plate to rotate, so that the six sets of molds A and B work alternately in a cycle to continuously perform injection molding, which makes the injection molding work more continuous and the work efficiency higher.

[0012] 2. In this utility model, through the cooling mechanism, the servo cylinder B extends, causing the cooling cover to be precisely locked outside the molds A and B that have completed the extrusion work. Then, the circulating water pump introduces the water tank into the chiller. After being cooled by the chiller, the water is poured from the outlet of the cooling cover onto the outside of molds A and B, rapidly cooling molds A and B, so that the toys inside molds A and B can be quickly cooled and formed, thus improving the cooling efficiency.

[0013] 3. In this utility model, through two implementation methods, it is easy to disassemble mold A from the support plate and replace it with new mold A and mold B to achieve the purpose of producing toys of different shapes, making it more flexible to use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In this utility model:

[0024] Reference Figure 1-7 An extrusion module for toy production includes a support frame 1, a slide plate 101 slidably connected above the support frame 1 via a slide rail, a servo electric cylinder A1011 installed on one side of the support frame 1, and the end of the servo electric cylinder A1011 connected to the slide plate 101, and a hot melt extruder 102 fixedly installed above the slide plate 101.

[0025] Above the support frame 1 is an extrusion mechanism that can continuously perform extrusion work, and a cooling mechanism that can quickly cool and shape the toy.

[0026] Example 1:

[0027] Reference Figure 1 , 2 In this embodiment, the extrusion mechanism includes a support plate 2, a servo motor 201, a mold A202, and a mold B203. The support plate 2 is rotatably connected to the other side of the support frame 1 via the servo motor 201. The support plate 2 is arranged in the shape of a disc. The mold A202 is movably connected to one side of the support plate 2, and the mold B203 is movably connected to one side of the mold A202. The contact areas of the mold A202 and the mold B203 are both bonded with sealing rubber rings. The back of the mold B203 is provided with an injection port that fits with the outlet of the hot melt extruder 102. The inner wall of the injection port and the outer wall of the outlet of the hot melt extruder 102 are both bonded with sealing rubber rings. The back of the mold A202 is symmetrically fixed with screws 2021. The surface of the support plate 2 is provided with through holes that fit with the screws 2021. The end of the screw 2021 is threaded with a limit nut. There are five molds A202, and the five molds A202 are equidistantly arranged around one side of the support plate 2.

[0028] The operator inserts the screw 2021 on the back of mold A202 through the corresponding through hole on the surface of support plate 2, and then uses a limiting nut to limit and fix the screw 2021, completing the installation of mold A202. Mold A202 can be replaced by unscrewing the limiting nut. Then, mold B203, corresponding to mold A202, is installed on one side of mold A202. Then, servo motor 201 drives support plate 2 to rotate, so that a set of molds A202 and mold B203 rotate to the bottom edge of support plate 2, and at this time, molds A202 and mold B203 are in a vertical state. Then, servo electric cylinder A1011 extends, pushing hot melt extruder 102 to move, so that the outlet of hot melt extruder 102 passes through the support plate. The raw material is fed into the injection port on the back of mold B203 at the bottom edge of plate 2. Then, the hot melt extruder 102 heats and conveys the raw material and extrudes it from the injection port into the cavity of mold A202 and mold B203, forming a toy shape that fits the cavity. Then, the servo cylinder A1011 retracts, driving the outlet of the hot melt extruder 102 to move out of the injection port. Then, the servo motor 201 drives the support plate 2 to rotate 72°, so that another set of molds A202 and mold B203 rotates to the bottom edge of the support plate 2, and continues the above work to extrude the next toy. This process is repeated, and the six sets of molds A202 and mold B203 work alternately in a cycle to continuously perform injection molding, making the injection molding work more continuous and efficient.

[0029] Reference Figure 2 , 3 4, 5. In this embodiment, a buckle 2031 is symmetrically fixedly installed on one side of the mold B203, and a spring block 2032 is elastically connected to one side of the buckle 2031. A slot that fits the buckle 2031 is embedded in one side of the mold A202, and a recess that fits the spring block 2032 is embedded inside the slot. A release rod 204 is symmetrically elastically connected to both sides of the mold A202 through a through groove, and the end of the release rod 204 extends into the recess.

[0030] The worker aligns mold B203 with mold A202, and the buckle 2031 is inserted into the slot. The spring block 2032 pops out when it encounters the recess, fixing the buckle 2031, thus aligning and fixing mold B203 and mold A202 together. The worker presses the release rod 204, which pushes the spring block 2032 out of the recess, allowing mold B203 and mold A202 to be separated smoothly, and the molded toy sandwiched between mold B203 and mold A202 is unloaded.

[0031] Reference Figure 1 , 2 5, 6. In this embodiment, the cooling mechanism includes a water tank 103, a circulating water pump 1031, a chiller 1032, a cooling cover 104, and a servo electric cylinder B1041. The water tank 103 is fixedly installed on the upper part of the support frame 1, corresponding to the support plate 2. The circulating water pump 1031 is connected to the outlet of the water tank 103 by a pipe. The chiller 1032 is fixedly installed below the support frame 1, and the chiller 1032 is connected to the circulating water pump 1031 by a pipe. The cooling cover 104 is installed on one side of the support frame 1 through the servo electric cylinder B1041. The cooling cover 104 has a cavity inside, and a water outlet hole communicating with the cavity is embedded in the inner wall of the cooling cover 104. The cooling cover 104 is connected to the chiller 1032 by a pipe, and an opening is provided at the bottom of the cooling cover 104.

[0032] Servo motor 201 drives support plate 2 to rotate 72°, and molds A202 and B203, which have completed injection molding, rotate to an inclined position. Servo cylinder B1041 extends, causing cooling cover 104 to be precisely locked outside molds A202 and B203, which are tilted and have completed extrusion. Then, circulating water pump 1031 introduces water from tank 103 into chiller 1032. After being cooled by chiller 1032, the water is poured from the outlet of cooling cover 104 onto the outside of molds A202 and B203, rapidly cooling them down and causing the toy inside molds A202 and B203 to cool and solidify quickly. This process is repeated.

[0033] Example 2:

[0034] In this utility model, in addition to fixing the mold A202 and the support plate 2 by the screw 2021 as described above, there is another embodiment;

[0035] Reference Figure 7 In this embodiment, a connecting rod 2022 is symmetrically fixedly installed on the back of the mold A202, and elastic pieces 2023 are symmetrically elastically connected on both sides of the connecting rod 2022. The surface of the support plate 2 is provided with through holes that fit with the connecting rod 2022.

[0036] Pass the connecting rod 2022 on the back of mold A202 through the corresponding through hole on the surface of support plate 2. The spring piece 2023 pops out to limit and fix the connecting rod 2022, thus completing the installation of mold A202. By pressing the spring piece 2023, the connecting rod 2022 can be smoothly disengaged from the through hole, thus completing the disassembly and replacement of mold A202.

[0037] Reference Figure 1 , 2 In this embodiment, the servo electric cylinder A1011, the hot melt extruder 102, the circulating water pump 1031, the chiller 1032, the servo electric cylinder B1041, and the servo motor 201 are all electrically connected to an external power supply through a control panel.

[0038] Working principle: First, the operator inserts the screw 2021 on the back of mold A202 through the corresponding through hole on the surface of support plate 2. Then, the screw 2021 is fixed by the limiting nut, completing the installation of mold A202. Alternatively, the connecting rod 2022 on the back of mold A202 is inserted through the corresponding through hole on the surface of support plate 2. The spring piece 2023 pops out to limit and fix the connecting rod 2022, completing the installation of mold A202. Next, mold B203 is aligned with mold A202. The buckle 2031 fits perfectly into the slot. The spring block 2032 pops out upon encountering the recess, fixing the buckle 2031, thus aligning and fixing mold B203 and mold A202 together. Then, the servo motor... Servo motor 201 drives the support plate 2 to rotate, causing a set of molds A202 and B203 to rotate to the lowest edge of the support plate 2, at which point molds A202 and B203 are in a perpendicular state. Then, servo cylinder A1011 extends, pushing the hot melt extruder 102 to move, causing the outlet of the hot melt extruder 102 to pass into the injection port on the back of mold B203 at the lowest edge of the support plate 2. The hot melt extruder 102 then heat-melts and extrudes the raw material from the injection port into the cavity between molds A202 and B203, forming a toy shape that fits the cavity. Afterwards, servo cylinder A1011 retracts, causing the outlet of the hot melt extruder 102 to move out of the injection port. Then, servo motor 201 drives the support plate 2 to rotate 72°, causing... Another set of molds, A202 and B203, rotates to the bottom edge of support plate 2 and continues the above process to extrude the next toy. Simultaneously, servo cylinder B1041 extends, causing cooling cover 104 to fit precisely outside the previously extruded molds A202 and B203. Then, circulating water pump 1031 pumps water from tank 103 into chiller 1032. After being cooled by chiller 1032, the water is poured from the outlet of cooling cover 104 onto the outside of molds A202 and B203, rapidly cooling them and causing the toy inside to cool and solidify quickly. Then, servo cylinders A1011 and B1041 retract simultaneously. Motor 201 drives support plate 2 to continue rotating 72°, repeating this process. The six sets of molds A202 and B203 work alternately in a cycle, continuously performing injection molding and cooling, resulting in higher work continuity and efficiency. Then, a worker stands on one side of support frame 1 and presses the release rods 204 on both sides of the cooled mold A202. The release rods 204 push against the spring block 2032, disengaging from the recess, allowing mold B203 to smoothly separate from mold A202. The molded toy sandwiched between mold B203 and mold A202 is then unloaded. Afterwards, mold B203 is reset. Finally, the worker can replace mold A202 by unscrewing the limit nut. Alternatively, pressing the spring piece 2023...Once the connecting rod 2022 is smoothly disengaged from the through hole, the disassembly and replacement of mold A202 can be completed.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
