Description

Technical Field

[0001] The present disclosure relates to the technical field of injection mold devices, and in particular to an injection molding mold structure and an injection mold device. Background Art

[0002] An injection mold assembly is an industrial device used to inject molten adhesive into a mold cavity, where it cools and solidifies to form a finished product. Injection mold assemblies are widely used in equipment manufacturing, electronics, automotive, aerospace, medical devices, and shipbuilding. They consist of a main unit and an injection mold structure, which is connected to the main unit.

[0003] In the prior art, the traditional injection molding mold structure includes a front template body, a pouring assembly and a molding assembly. The pouring assembly is connected to the front template body and the molding assembly, respectively. The pouring assembly is provided with a gate and a main channel. The molding assembly is provided with a cavity. The main channel is connected to the gate and the cavity, respectively. The gate is used to connect with the nozzle of an external injection molding machine, such as the Chinese patent number CN202010380074.8.

[0004] However, since the gate is used to connect with the nozzle of an external injection molding machine, the main channel is connected with the gate and the cavity respectively, so that the nozzle of the external injection molding machine can directly introduce the glue into the main channel through the gate. The transition path between the main channel and the gate is short, which makes it difficult for the glue to be buffered on the transition path between the main channel and the gate, so that the flow speed of the glue in the main channel is faster, so that the injection pressure of the glue into the cavity through the main channel is higher, so that the glue is injected into the cavity at a higher injection pressure, and the glue is cooled and solidified in the cavity to form a product, resulting in the outer surface of the product being more prone to pressure defects under the action of higher injection pressure, thereby making the appearance of the product less beautiful.

[0022] 2. Since the flow speed of the glue liquid in the injection channel is relatively slow, the injection pressure of the glue liquid entering the mold cavity through the injection channel is relatively low, so that the glue liquid is injected into the mold cavity at a lower injection pressure, thereby avoiding the problem in the prior art that the outer surface of the product is more likely to have pressure defect marks under the action of higher injection pressure, so that the outer surface of the product is less likely to have pressure defect marks under the action of lower injection pressure, thereby making the appearance of the product more beautiful.

[0060] Furthermore, if Figure 9 As shown, in one embodiment, the laterally placed forming portion 3231 is provided with a connecting bevel 3231b, and the connecting bevel 3231b abuts against the first forming surface 3221, so that the laterally placed forming portion 3231 abuts against the inclined end portion 322, so that the laterally placed forming portion 3231 limits the position of the inclined end portion 322, thereby making the laterally placed forming portion 3231 have better performance in limiting the position of the inclined end portion 322.

[0061] Furthermore, if Figures 8 and 9 As shown, the transverse placement forming portion 3231 is provided with a position-avoiding groove 3231c, which is in communication with the connecting through-hole 3232a, so that the connecting rod 3231a is respectively passed through the connecting through-hole 3232a and the position-avoiding groove 3231c, and the connecting rod 3231a is respectively slidably connected to the mounting base 3232 and the transverse placement forming portion 3231. In this embodiment, the connecting rod 3231a is slidably connected to the transverse placement forming portion 3231, so that the connecting rod 3231a slides relative to the transverse placement forming portion 3231, thereby facilitating the connecting rod 3231a to secure the product, making it more convenient for the connecting rod 3231a to secure the product.

[0062] Furthermore, if Figures 8 and 9 As shown, in one embodiment, there are multiple connecting rods 3231a, connecting holes 3232a, and avoidance grooves 3231c, each of which is provided in a one-to-one correspondence. In this embodiment, the number of connecting rods 3231a is multiple, so that multiple parts of the product can be fixed by corresponding connecting rods 3231a. The combined action of the multiple connecting rods 3231a provides better positional stability for the product, thereby improving the positional stability of the product within the mold cavity 1311.

[0063] Furthermore, if Figure 10 and Figure 13As shown, in one embodiment, the side flat end portion 324 is provided with a side flat groove 3241, which is in communication with the lower mold cavity 326. In this embodiment, the inner wall of the side flat groove 3241 abuts against the product so that the product is formed in the side flat groove 3241, thereby increasing the thickness of the product and improving the structural strength of the product.

[0064] Furthermore, if Figure 13 As shown, in one embodiment, the inner wall of the flat side groove 3241 is provided with a guide molding surface 3241a, and the guide molding surface 3241a is located between the lower mold cavity 326 and the flat side groove 3241. In this embodiment, the glue enters the lower mold cavity 326, and the glue in the lower mold cavity 326 flows along the guide molding surface 3241a into the flat side groove 3241, so that the product is formed in the flat side groove 3241, which is used to thicken the product and improve the structural strength of the product.

[0065] Furthermore, if Figure 10 and Figure 13 As shown, in one embodiment, the guide molding surface 3241a is inclined at a second predetermined angle, so that the side edge of the product formed in the side flat groove 3241 forms a side bevel, thereby avoiding the need for chamfering the side edge of the product, thereby saving product manufacturing steps, facilitating product production, and making the injection molding mold structure 10 more convenient for product production. In this embodiment, the second predetermined angle is 60° to 90°.

[0066] Furthermore, if Figure 13 As shown, in one embodiment, the inner wall of the side flat groove 3241 is provided with a positioning portion 3241b, and the positioning portion 3241b is used to be embedded in the product so that the product is formed with a positioning hole, which is beneficial to the molding and production of the product, so that the injection molding mold structure 10 is more convenient for the molding and production of the product.

[0067] The present disclosure also provides an injection mold device, including the injection molding mold structure 10 of any of the above-mentioned embodiments; wherein the injection molding mold structure 10 includes an upper mold assembly 100, a pouring part 200 and a lower mold assembly 300; the upper mold assembly 100 is provided with a mounting groove 1111a, a transition flow channel 121, an injection flow channel 122 and an upper mold cavity 131, and the mounting groove 1111a, the transition flow channel 121, the injection flow channel 122 and the upper mold cavity 131 are connected in sequence; the pouring part 200 is arranged in the mounting groove 1111a and is connected to the upper mold assembly 100, and the pouring part 200 is provided with a liquid inlet gate 210 for connecting with the nozzle of the injection molding machine, and the liquid inlet gate 210 is connected with the transition flow channel 121; the lower mold assembly 300 is detachably connected to the upper mold assembly 100, and the lower mold assembly 300 is provided with a lower mold cavity 326, and the lower mold cavity 326 is connected with the upper mold cavity 131 to form a cavity 1311 for molding a product.

[0068] Compared with the prior art, the present disclosure has at least the following advantages:

[0069] 1. Since the pouring part 200 is provided with a liquid inlet gate 210 for communicating with the nozzle of the injection molding machine, the liquid inlet gate 210 is communicated with the transition flow channel 121, so that the nozzle of the injection molding machine directly introduces the glue liquid into the transition flow channel 121 through the liquid inlet gate 210, and the transition flow channel 121 is sequentially communicated with the injection flow channel 122, so that the glue liquid flows along the transition flow channel 121 to the injection flow channel 122, so that the glue liquid flows out of the liquid inlet gate 210 and is indirectly introduced into the injection flow channel 122 through the transition flow channel 121, so that the transition path between the injection flow channel 122 and the liquid inlet gate 210 is longer under the action of the transition flow channel 121, thereby solving the problem of the prior art. Due to the short transition path between the main channel and the gate during the operation, the glue is easily buffered by the transition channel 121 in the transition path between the injection channel 122 and the liquid inlet gate 210, so that the glue flows smoothly under the buffering effect of the transition channel 121, thereby reducing the flow speed of the glue in the transition channel 121, so that the flow speed of the glue in the injection channel 122 is slower. The injection channel 122 is sequentially connected to the upper mold cavity 131, and the lower mold cavity 326 is connected to the upper mold cavity 131 to form a mold cavity 1311 for molding the product, so that the glue flows along the injection channel 122 into the mold cavity 1311;

[0070] 2. Since the flow speed of the glue in the injection channel 122 is relatively slow, the injection pressure of the glue into the mold cavity 1311 through the injection channel 122 is relatively low, so that the glue is injected into the mold cavity 1311 at a lower injection pressure, thereby avoiding the problem in the prior art that the outer surface of the product is more likely to have pressure defect marks under the action of higher injection pressure, so that the outer surface of the product is less likely to have pressure defect marks under the action of lower injection pressure, thereby making the appearance of the product more beautiful.

[0071] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
