Description

Technical Field

[0001] This utility model relates to the field of sensor housing processing technology, specifically a molding die for processing micro sensor housings for toy mechanisms. Background Technology

[0002] A sensor housing is a structural component that encloses and protects the precision components inside the sensor. It is typically made of engineering plastics, metal alloys, or composite materials and is formed through injection molding, die casting, or precision machining. It features sealing protection, impact resistance, temperature resistance, and electromagnetic shielding. A toy mechanism micro-sensor is a miniaturized electronic component embedded in the toy's power system. By integrating microelectromechanical systems, optical or pressure-sensitive technology, it detects signals such as motion posture, pressure, sound, or temperature in real time. These signals are converted into electrical signals by a built-in chip and transmitted to the control module, driving the toy to achieve motion feedback, voice interaction, or environmental response functions. It features low power consumption, high precision, and anti-interference characteristics and is widely used in intelligent dolls, remote-controlled models, and other scenarios to enhance the realism of interaction and intelligent experience.

[0003] Based on existing molding dies for processing micro-sensor housings in toy mechanisms, it was found that the existing molding dies have simple structures and all use traditional mold structures. However, the housing is a cylindrical structure, which makes it difficult to quickly remove the housing after stamping. This requires the installation of additional pneumatic components or additional negative pressure adsorption components, increasing costs and energy consumption. Therefore, this utility model designs a molding die for processing micro-sensor housings in toy mechanisms to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a molding die for processing the housing of a miniature sensor in a toy mechanism, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A molding die for processing a micro sensor housing in a toy mechanism includes a hydraulic cylinder, with a stamping mechanism and an ejector mechanism located below the hydraulic cylinder. The stamping mechanism includes an upper die fixed to the transmission end of the hydraulic cylinder, a stamping block embedded in the middle of the upper die, a lower die located below the upper die, and a molding groove formed in the middle of the lower die. The ejector mechanism includes a mounting base fixed to the bottom end of the lower die, a molding pad located in the molding groove, air chambers symmetrically arranged on the left and right sides of the lower die, and a piston seat slidably located in the air chamber. Limiting sleeves are fixed at both ends of the upper die, and limiting pins that slide with the limiting sleeves are fixed to the mounting base. The piston seat is connected to a connecting screw extending into the upper die via a first threaded sleeve, and a second threaded sleeve fixed to the inner wall of the upper die is threadedly connected to the top of the connecting screw. A silicone tube opening is provided in the middle of the molding pad, and an air supply pipe communicating with the silicone tube opening is installed at the bottom of the lower die. The air supply pipe is connected to the air chamber via an air injection pipe.

[0007] Optionally, the molding groove is an annular groove structure, and its inner wall and the outer wall of the molding pad form a molding cavity for the cylindrical sensor housing.

[0008] Optionally, the outer ring of the stamping block is provided with a buffer pad, the top of which is elastically connected to the upper mold via a spring seat.

[0009] Optionally, the sliding fit trajectory of the limiting sleeve and the limiting post is matched with the stamping stroke of the hydraulic cylinder.

[0010] Optionally, a hexagonal nut is fixed to the middle of the connecting screw, and its bottom end forms a detachable threaded connection with the first threaded sleeve.

[0011] Optionally, the silicone tube opening is fixedly installed on the surface of the molding pad, and the silicone tube opening is connected to the gas transmission pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a stamping mechanism is provided. The stamping mechanism significantly improves the consistency and stability of stamping by the precise cooperation between the stamping block and the molding groove, the guiding and limiting function of the limiting sleeve and the limiting post, and the elastic buffering design of the buffer pad and the spring seat. It is especially suitable for high-precision molding of thin-walled cylindrical shells, while reducing the risk of mold wear and workpiece deformation.

[0014] 2. In this utility model, a top-feeding mechanism is provided. The top-feeding mechanism uses the mechanical linkage of the air chamber, piston seat and connecting screw to convert the kinetic energy of the hydraulic cylinder into pneumatic power. The top-feeding is achieved through the silicone tube port, which not only avoids the mechanical damage to the molding shell caused by the traditional metal top rod, but also eliminates the need for an external air pump or negative pressure adsorption device, which greatly reduces energy consumption and equipment cost, while improving unloading efficiency and safety.

[0028] Please see Figures 1-9 In this embodiment of the invention, the molding die for processing the housing of a miniature sensor in a toy mechanism mainly consists of a hydraulic cylinder 1, a stamping mechanism 2, and an ejector mechanism 3.

[0029] Hydraulic cylinder 1: It is fixed to the workbench support by bolts, and its piston rod extends vertically downwards, with the end rigidly connected to the upper mold 201 to provide stamping power.

[0030] Stamping mechanism 2:

[0031] Upper mold 201: It is a rectangular metal block with a circular through hole in the center, and a stamping block 202 is embedded inside. The two are fixed by an interference fit.

[0032] Stamping block 202: It is a cylindrical hard alloy component with a polished surface at the lower end, used to directly contact the metal sheet and apply stamping force;

[0033] Lower mold 203: Fixed to the upper surface of mounting base 301, with an annular molding groove 204 in the middle, the inner diameter of which matches the outer diameter of stamping block 202;

[0034] Buffer pad 205: A ring-shaped metal block, sleeved on the outside of the stamping block 202, and elastically connected to the bottom of the upper mold 201 through the spring seat 206. The spring seat 206 is equipped with a compression spring to absorb stamping vibration.

[0035] Limiting components: Limiting sleeves 207 are welded to the left and right sides of the upper mold 201, and the corresponding positions of the mounting base 301 are vertically fixed with limiting posts 208. The surface of the limiting posts 208 is chrome-plated and polished, and it is fitted with the inner wall of the limiting sleeves 207 with a clearance to ensure that the alignment tolerance of the upper and lower molds 203 is less than 0.05mm.

[0036] Top material mechanism 3:

[0037] Mounting base 301: It is a cast iron base, which is fixed to the workbench by anchor bolts, and its top is welded to the lower mold 203;

[0038] Molding pad 302: It is a high-temperature resistant engineering metal disc, which is embedded in the middle of the molding groove 204. Its outer diameter is in clearance fit with the inner diameter of the molding groove 204. A silicone tube port 303 is installed on its surface, and the silicone tube port 303 is connected to the gas transmission pipe 304.

[0039] Pneumatic linkage components:

[0040] Air chamber 306: Four sets of air chambers 306 are symmetrically welded to the left and right sides of the lower mold 203, forming a closed cylindrical cavity;

[0041] Piston seat 307: is an aluminum alloy piston that has a sealing sliding fit with the inner wall of the air chamber 306, and the top is welded with the first threaded sleeve 308;

[0042] Connecting screw 309: It is a high-strength steel screw. Its lower end is threaded to the first threaded sleeve 308, and a hexagonal nut 310 is welded to the middle. Its upper end passes through the reserved hole of the upper mold 201 and is threaded to the second threaded sleeve 311. The second threaded sleeve 311 is welded to the inner wall of the upper mold 201.

[0043] Gas passage: Gas pipeline 304 is a stainless steel rigid pipe, which is embedded in the lower mold 203. One end is connected to the silicone tube port 303, and the other end is connected to the gas chamber 306 through the gas injection pipeline 305.

[0044] The working principle of this utility model is as follows: This molding die, driven by a hydraulic cylinder 1, coordinates the stamping mechanism 2 and the linked ejector mechanism 3 to achieve efficient stamping and automatic unloading of the micro-sensor housing. The specific working process is as follows: During operation, the mounting base 301 is fixed to the worktable. The hydraulic cylinder 1 drives the upper mold 201 to move downwards, and the stamping block 202 presses down synchronously with the upper mold 201, pressing the metal sheet placed on the surface of the lower mold 203 into the molding groove 204. The cylindrical housing is formed through the cooperation of the annular groove structure and the outer wall of the molding pad 302. During this process, the limiting sleeves 207 on both sides of the upper mold 201 slide along the limiting posts 208 to ensure precise alignment between the stamping block 202 and the molding groove 204; the buffer pad 205 on the outside of the stamping block 202 cooperates with the spring seat 206 to absorb impact force and protect the formed housing. Simultaneously, when the upper mold 201 presses down, it drives the connecting screw 309 and the first threaded sleeve 308 in conjunction with the second threaded sleeve 311, forcing the four sets of piston seats 307 to move down synchronously in the air chamber 306 to compress air. The high-pressure gas enters the air supply pipe 304 through the air injection pipe 305, and finally acts evenly on the bottom of the metal sheet through the silicone tube 303 in the middle of the molding pad 302, forming an upward thrust. After the stamping is completed, the hydraulic cylinder 1 returns and lifts the upper mold 201, the stamping block 202 separates from the metal sheet, and the pressurized gas in the air chamber 306 is quickly depressurized as the piston seats 307 rebound. The air pressure released by the silicone tube 303 pushes the molded shell away from the molding groove 204, realizing contactless unloading and avoiding the risk of scratching the shell by the traditional metal ejector rod.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
