Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an endoscope shell mold with anti-sticking function for top materials. Background Art

[0002] An injection mold is a tool used to produce plastic products. Its function is to give plastic products a complete structure and precise size. It consists of a mold base, a mold core, a mold cavity, a guide plate, an ejection mechanism, a cooling system and other parts. Each part has its specific function and role. Injection molds have the advantages of high precision, high efficiency, suitability for large-scale production, the ability to produce plastic products with complex structures, short molding cycles, and relatively low production costs. They are widely used in automotive parts, home appliances, daily necessities, medical devices, industrial parts and other fields.

[0003] In the existing injection mold, when the molded module is cooled, there is an obstruction between the ejector pin and the cooling channel, which makes the module part on the top of the ejector pin suffer from poor cooling under the condition of high-efficiency production and short cooling time, and it is easy to cause sticking during ejection. Therefore, we propose an endoscope shell mold with anti-sticking ejection material. Utility Model Content

[0007] Preferably, the top plate and the reinforcement column match the matching opening, and the top plate is a circular plate structure.

[0008] Preferably, the anti-sticking component also includes a socket formed through the lower portion of the reinforcing column, and a threaded hole formed in a top pin outside the socket.

[0009] Preferably, the anti-sticking component further comprises a hexagon socket screw movably mounted in both the threaded hole in the ejector pin and the socket.

[0010] Preferably, the injection mold further comprises an endoscope shell module injected between the upper cavity and the lower cavity.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, the matching opening opened at the top of the ejector cavity in the lower cavity can make the thickness of the top plate in the matching opening close to the bottom water-cooling channel and the thickness between the water-cooling channel and the top inner mirror shell module almost the same, so that the water-cooling channel can well cool the part of the inner mirror shell module on the top of the top plate, thereby avoiding the problem of sticking during discharge caused by poor cooling due to the top of the conventional ejector blocking the water-cooling channel. At the same time, the large-sized ejector plate at the top of the ejector can also have a larger force-bearing area when ejecting a thinner inner mirror shell module, thereby reducing the problem of deformation of the ejector position during discharge of the inner mirror shell module.

A matching port 206 is opened in the lower cavity 104 at the top of the ejector cavity 201, and the matching port 206 is a T-column-shaped structure. A water-cooling channel 207 is also opened in the lower cavity 104 outside the matching port 206. The top plate 205 and the reinforcement column 204 are matched with the matching port 206, and the top plate 205 is a circular plate-shaped structure. The anti-sticking component 200 also includes a socket 208 that passes through the lower part of the reinforcement column 204, and a threaded hole 209 that is opened in the ejector 202 outside the socket 208. The anti-sticking component 200 also includes a hexagonal screw 210 that is movably installed in the threaded hole 209 in the ejector 202 and the socket 208.

[0024] Specifically, the injection mold 100 is a tool for producing plastic products, and its function is to give the plastic products a complete structure and precise size. It is composed of a mold base, a template, a mold cavity, a guide plate, an ejection mechanism, a cooling system, etc. Each part has its specific function and role. The matching port 206 opened at the top of the ejector cavity 201 in the lower cavity 104 of the injection mold 100 can make the thickness of the top plate 205 in the matching port 206 from the bottom water-cooling channel 207 and the thickness between the water-cooling channel 207 and the top inner mirror shell module 105 almost the same, so that the water-cooling channel 207 can block the upper inner mirror shell module 105 of the top plate 205.

[0025] The working principle and use process of this utility model:

[0026] When water flows through the water-cooling channel 207 in the lower cavity 104 to cool the inner mirror shell module 105 injected at the upper end, the water will flow to the parts outside the multiple groups of matching ports 206, and then cool the shielding parts at the bottom of the inner mirror shell module 105 on the top of the top plate 205 through the thinner top plate 205, so as to ensure the rapid cooling and molding of various parts of the inner mirror shell module 105 at the upper end of the lower cavity 104. When the inner mirror shell module 105 is cooled and molded and discharged, the ejector pin 202 will eject the inner mirror shell module 105 through the top plate 205 with a large force-bearing area, thereby avoiding the deformation problem of the thinner inner mirror shell module 105 during ejection.
