Abstract
Description
Technical Field
[0001] This utility model relates to the field of musical toy processing, and in particular to a musical toy injection molding device. Background Technology
[0002] Toys, broadly speaking, refer to items that can be played with. Playing with toys is often used as a form of edutainment in human society. Toys can also be natural objects, that is, non-man-made things such as sand, stones, mud, and twigs. The term "toy" should be interpreted broadly; it is not limited to items sold on the street for playing with. Anything that can be played with, seen, heard, and touched can be called a toy. Toys are suitable for children, but even more so for young adults and the elderly. They are tools for opening the windows of wisdom, making people intelligent and clever. Musical toys are toys that can produce music. Examples include dolls and animals that produce musical sounds or songs. Musical toys help young children learn to distinguish different musical instrument sounds, differentiate between loud and soft sounds, and develop auditory perception. Plastic musical toys are loved by consumers for their excellent weather resistance, flexibility, and malleability.
[0003] However, traditional musical toys, such as those disclosed in the patent application CN201220557918.2 entitled "Music Box Toy," require injection molding equipment to produce multiple assembly parts during the manufacturing process. However, traditional injection molding equipment is inefficient. Utility Model Content
[0004] Therefore, it is necessary to provide a musical toy injection molding device to address the technical problem of low efficiency in traditional injection molding equipment.
[0005] A musical toy injection molding apparatus, comprising: a twin-screw extruder, an injection mold, a cooling mechanism, and a control mechanism;
[0006] The injection mold includes an upper mold and a lower mold, which are adapted to each other and detachably connected. The upper mold and the lower mold are connected to form a mold cavity. The upper mold has an injection hole that communicates with the mold cavity. The twin-screw extruder performs injection molding into the mold cavity through the injection hole. The lower mold has a cooling cavity that surrounds the mold cavity. The lower mold has heat exhaust ports on both sides near the end of the upper mold that communicate with the cooling cavity. The bottom of the lower mold has an insertion hole that communicates with the cooling cavity.
[0007] The cooling mechanism includes an air conditioner, a cold air duct, a receiving base, and two temperature sensors. The output end of the air conditioner is connected to the input end of the cold air duct. The receiving base is a hollow cuboid structure with one open end. A receiving block is provided on the inner wall of the bottom of the receiving base, and an insertion tube is provided on the top of the receiving block. A cooling channel is opened inside the receiving block, and the cold air duct is connected to the insertion tube through the cooling channel. The insertion tube is adapted to the insertion hole, is inserted into the insertion hole, and is connected to the lower mold. A locking block is provided on each of the two parallel inner walls at the open end of the receiving base. A heat dissipation channel is opened at one end of the locking block, and a heat dissipation hole is opened on the side wall of the locking block. The heat dissipation hole is connected to one end of the heat dissipation channel. The end of the heat dissipation channel away from the heat dissipation hole is connected to the heat dissipation port. Each temperature sensor is correspondingly installed in one of the heat dissipation channels.
[0008] The twin-screw extruder, the air conditioner, and the two temperature sensors are all electrically connected to the control mechanism.
[0009] In one embodiment, the receiving block and the receiving seat are integrally formed.
[0010] In one embodiment, the receiving block has a cuboid structure.
[0011] In one embodiment, the receiving block is a cylindrical structure.
[0012] In one embodiment, the insertion tube and the receiving block are integrally formed.
[0013] In one embodiment, the insertion tube is a circular tube.
[0014] In one embodiment, the locking block has a cuboid structure.
[0015] In one embodiment, the locking block is a cylindrical structure.
[0016] In one embodiment, the locking block and the receiving seat are integrally formed.
[0017] In one embodiment, the cold air duct is wrapped with heat insulation cotton.
[0018] During operation, the aforementioned musical toy injection molding device places the lower mold on the receiving block, simultaneously inserting the insertion tube into the insertion hole and connecting it to the lower mold. Both locking blocks on the lower mold abut against it, ensuring the end of the heat dissipation channel away from the heat dissipation hole connects to the heat dissipation port. The upper mold is then placed on the lower mold to form the mold cavity. An external drive unit moves the twin-screw extruder above the injection mold, specifically aligning the output end of the twin-screw extruder with the injection hole. The twin-screw extruder injects material into the mold cavity through the injection hole. After injection, the external drive unit removes the twin-screw extruder. The air conditioner discharges cold air into the cooling chamber through the cold air duct, cooling channel, and insertion tube. The cold air slowly rises and passes through the lower mold to fully cool the product within the mold cavity, accelerating injection molding and solidification. The cold air slowly rises and dissipates heat through the heat dissipation port, heat dissipation channel, and heat dissipation hole. When the temperature detected by the temperature sensor remains below a preset time, it indicates that the product within the mold cavity has cooled and solidified. The aforementioned musical toy injection molding device has high efficiency in the injection molding process of musical toys. Attached Figure Description

[0029] The cooling mechanism 300 includes an air conditioner 310, a cold air duct 320, a receiving seat 330, and two temperature sensors 340. The output end of the air conditioner 310 is connected to the input end of the cold air duct 320. The receiving seat 330 is a hollow cuboid structure with one open end. A receiving block 331 is provided on the inner wall of the bottom of the receiving seat 330. In this embodiment, the receiving block 331 and the receiving seat 330 are integrally formed. The receiving block 331 is a cuboid structure. In another embodiment, the receiving block 331 is a cylindrical structure. An insertion tube 332 is provided on the top of the receiving block 331. In this embodiment, the insertion tube 332 and the receiving block 331 are integrally formed. The insertion tube 332 is a circular tube.
[0030] A cooling channel 301 is provided inside the receiving block 331, and a cold air duct 320 is connected to the insertion tube 332 through the cooling channel 301. In this embodiment, the cold air duct 320 is wrapped with heat insulation cotton to reduce energy consumption. The insertion tube 332 is adapted to the insertion hole 205, and the insertion tube 332 is inserted into the insertion hole 205 and connected to the lower mold 220. A locking block 333 is provided on each of the two parallel inner walls at the open end of the receiving seat 330. In this embodiment, the locking block 333 has a cuboid structure. In another embodiment, the locking block 333 has a cylindrical structure. Specifically, the locking block 333 and the receiving seat 330 are integrally formed. A heat dissipation channel 302 is provided at one end of the locking block 333, and a heat dissipation hole 303 is provided on the side wall of the locking block 333, which is connected to one end of the heat dissipation channel 302.
