Description

Technical Field

[0001] The utility model relates to a hot runner system, and more particularly to a hot runner manifold plate. Background Art

[0002] The hot runner system is a technology widely used in plastic injection molding. It uses a heating system to keep specific areas in the mold at a high temperature, thereby ensuring the fluidity and filling performance of the plastic during the injection molding process. The hot runner manifold is a core component in the hot runner system. It is responsible for distributing the plastic melt transmitted from the main runner nozzle to the nozzles of each injection point through the runner.

[0003] Existing hot runner manifolds are divided into two types: internal heating and external heating. The externally heated hot runner manifold is formed by opening a heating groove in the direction parallel to the plate body and filling the heating groove with a heating rod to heat the runner from the outside of the runner. The external heating method can avoid local overheating. At the same time, the flow resistance in the runner is small, the runner is easy to process, and the maintenance is convenient.

[0004] Existing hot runner manifolds usually have copper attached to the surface of the heating tank. Copper has very good thermal conductivity, which enables the attached copper strips to better transfer the heat of the heating rod to various parts of the manifold. At the same time, the copper strips effectively shield the heating rods, thereby reducing heat loss from the heating rods. However, the existing copper strips are embedded in the heating tank by hammering. If the operator does not operate properly, the hammer hitting the surface of the manifold can easily cause damage to its internal structure. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a hot runner manifold.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a hot runner diverter plate, comprising a plate body and a plurality of heating grooves provided on the plate body, wherein buffer strips are detachably installed on both sides of the heating grooves on the plate body, a plurality of insert heads are provided at the bottom of the buffer strips, a plurality of embedding grooves for embedding the insert heads are provided on the plate body, a convex ring 1 is circumferentially provided on the outer peripheral wall of the embedding head, and a convex ring 2 is provided in the embedding groove for interfering with the convex ring 1 and limiting the embedding head from escaping from the embedding groove.

[0007] The present invention is further configured as follows: a receiving groove for receiving the bottom of the buffer strip is opened on the plate body, and the thickness of the buffer strip is greater than the depth of the receiving groove.

[0008] The utility model is further configured as follows: the accommodating groove and the heating groove are communicated with each other, and one side of the buffer bar is used to contact the copper bar.

[0009] The utility model is further configured as follows: an easy-to-tear piece is integrally formed at one end of the buffer strip.

[0010] The utility model is further configured as follows: a positioning groove is provided on the side wall of the accommodating groove at the shortest distance from the embedding groove to the side wall of the accommodating groove, and a positioning strip is provided on the buffer strip for embedding into the positioning groove and keeping the embedding head aligned with the embedding groove.

[0011] The utility model is further configured as follows: the buffer strip, the embedded head, the convex ring and the positioning strip are all integrally formed of rubber material.

[0012] In summary, the utility model has the following beneficial effects: the utility model can avoid direct contact between the hammer and the plate body and buffer the impact force generated by the hammer hitting by setting a buffer strip, thereby reducing damage to the diverter plate caused by improper operation of the operator. At the same time, the convex ring 1 is driven to move by the embedded head, thereby controlling the position change between the convex ring 1 and the convex ring 2 in the embedded groove, thereby realizing the disassembly and assembly of the buffer strip, and the operation is relatively convenient.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] See Figure 1-2As shown, a hot runner manifold comprises a plate body 1 and a plurality of heating grooves 2 provided on the plate body 1, buffer strips 3 are detachably mounted on both sides of the heating grooves 2 on the plate body 1, a plurality of inserting heads 4 are provided at the bottom of the buffer strips 3, a plurality of embedding grooves 5 for embedding the inserting heads 4 are provided on the plate body 1, a convex ring 6 is provided circumferentially on the outer peripheral wall of the inserting head 4, and a convex ring 2 7 is provided in the embedding groove 5 for contacting with the convex ring 6 and limiting the inserting head 4 from escaping from the embedding groove 5. Before performing the copper attaching operation, the buffer pad can be installed first. It is fixed on the plate body 1. The specific operation is to align the embedding head 4 at the bottom of the buffer strip 3 with the embedding groove 5 until the convex ring 1 6 and the convex ring 2 7 conflict with each other, and then press the buffer strip 3 to apply a downward pressure on the embedding head 4. At this time, the convex ring 1 6 and the convex ring 2 7 squeeze and deform each other, and the embedding head 4 drives the convex ring 1 6 to continue to move downward until the convex ring 1 6 passes over the convex ring 2 7. At this time, the two sides of the convex ring 1 6 conflict with the convex ring 2 7 and the inner bottom wall of the embedding groove 5 respectively, and the convex ring 1 6 is limited in the embedding groove 5, thereby limiting the embedding head 4 is released from the embedding groove 5. The locking mechanism of the convex ring 1 6 and the convex ring 2 7 can firmly fix the buffer strip 3 on the plate body 1. When the copper attaching operation of the manifold is performed, the buffer strip 3 has a buffering effect on the falling hammer. After the copper attaching operation is completed, the buffer strip 3 can be pulled upward to drive the embedding head 4 to move upward. The force generated by the upward movement of the embedding head 4 causes the convex ring 1 6 and the convex ring 2 7 to squeeze and deform each other until the convex ring 1 6 passes over the convex ring 2 7. The limit state of the convex ring 1 6 in the embedding groove 5 is released. The buffer strip 3 can be removed from the plate body 1, thereby avoiding the presence of the buffer strip 3 affecting the normal operation of the diverter plate. By setting the buffer strip 3, direct contact between the hammer and the plate body 1 can be avoided and the impact force generated when the hammer hits can be buffered, thereby reducing damage to the diverter plate caused by improper operation of the operator. At the same time, the convex ring 1 6 is driven to move by the inserting head 4, thereby controlling the position change between the convex ring 1 6 and the convex ring 2 7 in the inserting groove 5, thereby realizing the disassembly and assembly of the buffer strip 3, and the operation is relatively convenient.

[0018] See Figure 1-2As shown, a receiving groove 8 is provided on the plate body 1 for accommodating the bottom of the buffer bar 3, and the thickness of the buffer bar 3 is greater than the groove depth of the receiving groove 8. Through the setting of the receiving groove 8, the bottom of the buffer bar 3 can be accommodated in the receiving groove 8, and the receiving groove 8 further limits the buffer bar 3, thereby preventing the buffer bar 3 from slipping on the surface of the plate body 1 during installation or impact. At the same time, the part exposed by the receiving groove 8 reserves sufficient buffering distance, which is conducive to ensuring the buffering effect of the buffer bar 3. The receiving groove 8 is interconnected with the heating groove 2, and one side of the buffer bar 3 is used to contact the copper bar. Since the receiving groove 8 and the heating groove 2 are interconnected, when the buffer bars 3 on both sides of the heating groove 2 are fixed in the receiving groove 8, they can limit the copper bar. When the copper bar is placed on the surface of the plate body 1, the two sides of the copper bar respectively contact the buffer bars 3 on both sides, thereby preventing the copper bar from slipping on the surface of the plate body 1 during knocking, which is convenient for the operator to perform copper attaching operations.

[0019] See Figure 1-2 As shown, an easy-tear piece 9 is integrally formed at one end of the buffer strip 3. The easy-tear piece 9 provides a stable fulcrum for the operator, so that the operator can hold the easy-tear piece 9 to apply tension during the operation of removing the buffer pad, making it easier for the operator to remove the buffer pad. A positioning groove 10 is provided on the side wall of the accommodating groove 8 at the shortest distance from the embedding groove 5 to the side wall of the accommodating groove 8. A positioning strip 11 is provided on the buffer strip 3 for embedding into the positioning groove 10 and keeping the embedding head 4 aligned with the embedding groove 5. When fixing the buffer strip 3, the operator can align the positioning strip 11 with the positioning groove 10 and embed it. Since the positioning groove 10 is located on one side of the accommodating groove 8, the corresponding positioning strip 11 is also located on one side of the buffer strip 3. The operator can more intuitively see the position change between the positioning groove 10 and the positioning strip 11. By embedding the positioning strip 11 into the positioning groove 10, the embedding head 4 can be easily aligned with the embedding groove 5 and embedded, eliminating the alignment operation of the embedding groove 5 and the embedding head 4, thereby facilitating the operator to fix the buffer strip 3. At the same time, the positioning strip 11 is embedded in the positioning groove 10, further improving the connection stability between the buffer strip 3 and the plate body 1. The buffer strip 3, the embedding head 4, the convex ring 6 and the positioning strip 11 are all integrally formed of rubber material. The rubber material has good elasticity and resilience, thereby ensuring that the buffer strip 3 has a good buffering effect. At the same time, the convex ring 7 has good deformation ability.
