Description

Technical Field

[0001] The utility model relates to the technical field of door and window profile moulds, in particular to a bracket plate used for door and window profiles. Background Art

[0002] The material flow channel support plate structure of the door and window profile injection mold is a solid and wear-resistant metal plate. The molten plastic is guided to flow along a predetermined path through a carefully designed flow channel system to ensure that the mold cavity is fully filled. The support plate is connected to the cooling system. Through the circulation of the cooling medium, the door and window profile being formed is quickly cooled to promote its rapid solidification. As a key component in the injection molding process, the material flow channel support plate not only guides the plastic flow to ensure uniform filling, but also distributes the flow channel pressure to prevent defects caused by uneven flow. For example, a support plate for UPVC door and window profiles disclosed in the authorization announcement number CN207059172U includes a support plate body, and the support plate body is sequentially provided with a first feed flow channel, a second feed flow channel, a third feed flow channel and a fourth feed flow channel from bottom to top; first flow-blocking ribs are provided at both ends of the first feed flow channel and between the second feed flow channel, and the A fifth feed channel is arranged above the middle of the first feed channel, a second flow-blocking rib is arranged at one end of the lower side of the fourth feed channel, and a third flow-blocking rib is arranged at the other end of the lower side of the fourth feed channel, etc. Through the separate feeding of the local structure and the reasonable design of the flow-blocking ribs, the strength of the junction of the internal ribs and the molding quality of the door and window profiles are improved. However, this technical solution mainly arranges a plurality of separate feed channels. When the material in a molten state enters the mold cavity through the flow channel and the support plate, the molten material in a high-pressure and high-temperature state is likely to affect the structural stability of the support plate, that is, the molten material has high fluidity and corrosiveness. Long-term high temperature action will cause deformation, wear or corrosion of the support plate, reducing its service life, and in a high-temperature environment, the temperature difference in different flow channels may be large, which leads to uneven flow velocity and pressure distribution of the molten material in the flow channel, affecting the molding quality of the final product.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: a bracket plate for door and window profiles, comprising a bracket plate outer ring 1 and guide rings 3 arranged on the front and rear outer walls of the bracket plate outer ring 1, the bracket plate inner ring 2 is integrally formed inside the bracket plate outer ring 1, a material diversion structure is arranged inside the bracket plate outer ring 1 and the bracket plate inner ring 2, a four-point support arm structure is installed on the outer wall of the guide ring 3 on one side close to the bracket plate outer ring 1, a central drainage structure is installed between the two guide rings 3, and convex plates 6 are integrally formed on the outer walls of both sides of the guide ring 3;

[0020] The material diversion structure is an arc-shaped flow-around cavity 101 arranged on both sides of the inner ring 1 of the support plate, and a rectangular flow-around cavity 201 arranged on both sides of the inner ring 2 of the support plate. The arc-shaped flow-around cavity 101 and the rectangular flow-around cavity 201 can avoid uneven pressure generated during the material flow process in the flow channel through material diversion, which helps to prevent uneven filling of the molten material in the mold cavity due to the pressure difference in the flow channel;

[0021] The four-point support arm structure is four symmetrical leg supports 301 integrally formed on the outer wall of one side of the guide ring 3. The end of the leg support 301 away from the guide ring 3 is fixedly connected to the outer wall of one side of the inner ring 2 of the bracket plate. A rectangular cut-out portion 302 is provided on the outer wall of the leg support 301. The four leg supports 301 integrally formed on the back of the guide ring 3 are fixedly connected to the outer wall of one side of the outer ring 1 of the bracket plate. The four leg supports 301 are evenly distributed, which reduces the possibility of stress concentration, effectively shares the external pressure, and reduces the deformation risk of the outer ring 1 and the inner ring 2 of the bracket plate at high temperature.

[0022] The central drainage structure is a drainage pipe 4 installed between two guide rings 3, and a cone head 5 fixed at one end of the drainage pipe 4. The drainage pipe 4 and the cone head 5 serve to drain the high-temperature molten material, so that the material flows more concentratedly in the mold flow channel.

[0023] A docking piece 8 is fixed on the outer wall of the embossed plate 6 on one side close to the outer ring 1 of the bracket plate, and hollow rectangular shells 7 for mutual insertion with the docking piece 8 are symmetrically installed on the outer walls of both sides of the outer ring 1 of the bracket plate, and hollow shells 9 are installed on the top and bottom of the hollow rectangular shell 7. Two positioning blocks 10 are installed on the outer wall of the embossed plate 6 on one side close to the outer ring 1 of the bracket plate, and a limiting hole 1001 is arranged inside the positioning block 10, and an elastic locking structure that cooperates with the limiting hole 1001 is installed inside the hollow shell 9;

[0024] The back of the guide ring 3 is plugged into the inside of the hollow shell 7 through the docking piece 8, and the positioning block 10 is firmly positioned by using the elastic locking structure inside the hollow shell 9, so as to ensure the stable connection between the outer ring 1 of the bracket plate and the embossed plate 6, so that the bracket plate can better withstand the pressure and temperature changes in the production process, reducing the risk of accidental damage or shutdown;

[0025] The elastic locking structure is a plurality of conical springs 901 fixed inside the hollow shell 9, and a slide 902 installed together at the top of the plurality of conical springs 901. A limit pin 903 is fixed at the top of the slide 902. The top of the limit pin 903 penetrates to the outside of the hollow shell 9 and is plugged into the limit hole 1001. When the docking piece 8 and the hollow moment shell 7 are plugged into place, the conical spring 901 forces the slide 902 and the limit pin 903 to move upward until the end of the limit pin 903 is pushed into the limit hole 1001, thereby locking the hollow shell 9 and the positioning block 10.

[0026] When the embodiment of the present application is in use, first, the staff installs the bracket plate into the flow channel of the door and window profile injection mold, that is, the outer ring 1 of the bracket plate is fixed in the flow channel, and the high-temperature molten material in the flow channel flows through the outer ring 1 of the bracket plate, the inner ring 2 of the bracket plate and the inside of the drainage tube 4, wherein the material diversion structure between the outer ring 1 of the bracket plate and the inner ring 2 of the bracket plate can break up the material, and the material diversion structure can effectively guide the molten material to different parts of the mold to ensure that each area in the mold cavity can be evenly filled. In this process, the front side of the outer ring 1 of the bracket plate needs to be impacted by the high-temperature molten material. At this time, the guide ring 3 and the four-point support arm structure are used to improve the structural strength of the outer ring 1 of the bracket plate and the inner ring 2 of the bracket plate, so that the bracket plate is more stable and reliable when subjected to molten materials under high pressure and high temperature, reducing the risk of deformation or damage, and helping to ensure the long-term stable operation of the mold during the production process and extending its service life.
