Description

Technical Field

[0001] The utility model relates to the technical field of positioning metal parts of rubber-coated molds, in particular to a mold positioning mechanism and a rubber-coated mold. Background Art

[0002] With the widespread adoption of injection molding in modern manufacturing, metal inserts, encapsulated within plastic products to enhance their structural and functional properties, have become a common design technique. However, the actual injection molding process presents a number of challenges, most notably the stability of the metal inserts. These issues include, but are not limited to, the metal insert falling out of the mold, difficulty accurately placing the insert due to interference, and, in particular, the potential for metal inserts to deform during installation.

[0003] The stability of metal inserts directly impacts the quality and production efficiency of injection molded products. To overcome these issues, optimizing the strength and shape of metal parts to improve the reliability of overmolding has been a common approach. However, while this strategy can address stability issues to a certain extent, it also comes with significant additional costs. On the one hand, the use of high-strength materials significantly increases the cost of metal inserts; on the other hand, the complex shape design not only increases mold design difficulty and manufacturing costs, but also increases the number of mold trials, prolonging the product development cycle, and affecting overall production efficiency.

[0004] In summary, the traditional structure directly presses the metal parts into the mold core, which is not only difficult to place and the force is difficult to control, but also easy to deform the metal parts. Utility Model Content

[0005] The purpose of the utility model is to provide a mold positioning mechanism and a rubber-coated mold to alleviate the technical problem in the prior art that the traditional structure directly presses the metal parts into the mold core, which is not only difficult to insert and the force is difficult to control, but also easy to deform the metal parts.

[0008] The position adjustment block is slidably mounted on the mold body;

[0009] One end of the elastic member is connected to the position adjustment block, and the other end of the elastic member is connected to the fixed block. The elastic member is configured so that the fixed block has a movement tendency to move away from the position adjustment block, so that the fixed block clamps the metal part.

[0010] In an alternative embodiment,

[0015] In an alternative embodiment,

[0016] The position adjustment block is provided with an elongated hole, and the connecting member passes through the elongated hole and is connected to the mold body, so that the position adjustment block can be adjusted to a fixed position in the mounting groove.

[0017] In an alternative embodiment,

[0028] In a second aspect, the rubber-coated mold provided by the present invention includes the mold positioning mechanism.

[0029] The mold positioning mechanism provided by the utility model is realized by slidingly installing a fixed block and a position adjusting block on the mold main body.

[0039] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0040] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the mold positioning mechanism provided in this embodiment is used to position the metal part 500, including: a fixed block 100, a position adjustment block 200 and an elastic member 300; the fixed block 100 is slidably installed on the mold body 400, and the fixed block 100 is used to support the metal part 500. Specifically, a mounting groove 410 is provided on the mold body 400, and the fixed block 100 is placed in the mounting groove 410 so that the fixed block 100 can slide along the mounting groove 410.

[0041] The position adjustment block 200 is slidably mounted on the mold body 400 . Specifically, the position adjustment block 200 is placed in the mounting groove 410 and can be fixed in the mounting groove 410 to keep the position of the position adjustment block 200 different.

[0042] One end of the elastic member 300 is connected with the position adjusting block 200, and the other end of the elastic member 300 is connected with the fixing block 100, and the elastic member 300 is specifically provided as a compression spring, and the elastic member 300 is configured to have a movement tendency of moving away from the position adjusting block 200, so as to make the fixing block 100 clamp the metal piece 500.

[0043] When the metal piece 500 is placed on the fixing block 100, the fixing block 100 moves towards the position adjusting block 200, and the elastic member 300 is compressed, and the elastic force generated by the elastic member 300 makes the fixing block 100 clamp the metal piece 500, and the position of the position adjusting block 200 in the installation groove 410 is adjusted, so as to adjust the size of the elastic force generated by the elastic member 300, when the metal piece 500 is observed to be deformed, it means that the clamping force is too large, the position of the position adjusting block 200 is adjusted away from the fixing block 100, and the clamping force is reduced, when the metal piece 500 is clamped and then falls off, it means that the clamping force is too small, and the position of the position adjusting block 200 is adjusted towards the fixing block 100, and the clamping force is increased.

[0044] In an optional embodiment, the mold positioning mechanism further comprises a connecting member 600; the connecting member 600 is connected with the mold body 400 through the position adjusting block 200, so as to fix the position adjusting block 200 in the installation groove 410.

[0045] Specifically, the connecting member 600 is specifically provided as a connecting bolt, and a connecting hole is formed in the position of the mold body 400 corresponding to the installation groove 410, and the connecting bolt is inserted into the connecting hole through the position adjusting block 200, so as to fix the position of the position adjusting block 200.

[0046] In an optional embodiment, the position adjusting block 200 is provided with a long hole 210, and the connecting member 600 is connected with the mold body 400 through the long hole 210, so that the position adjusting block 200 can be adjusted at the fixed position of the installation groove 410.

[0047] Specifically, the long hole 210 is formed in the position adjusting block 200, and the long hole 210 is configured to make the connecting member 600 slide relative to the position adjusting block 200, so as to freely adjust the position of the position adjusting block 200 in the installation groove 410, and then adjust the distance between the position adjusting block 200 and the fixing block 100, so as to achieve the effect of adjusting the elastic force of the elastic member 300.

[0048] In addition, optionally, as an alternative to setting a long hole 210 in the position adjustment block 200, a long hole 210 can also be opened at the position of the mold body 400 located in the installation groove 410, and a connecting hole can be set on the position adjustment block 200. Through the cooperation of the long hole 210 and the connecting member 600, the position of the position adjustment block 200 in the installation groove 410 can be adjusted. The specific setting position of the long hole 210 is selected according to actual conditions.

[0049] In an optional embodiment, a chamfered structure 110 is provided at the end of the fixing block 100, and the chamfered structure 110 contacts the metal part 500. The chamfered structure 110 is adapted to the side wall shape of the metal part 500 to ensure that the chamfered structure 110 is in stable contact with the metal part 500. The setting of the chamfered structure 110 avoids scratching the metal part 500.

[0050] In an optional embodiment, the mold positioning mechanism further includes a guide block 700 ; the guide block 700 is mounted on the mold body 400 , and the guide block 700 can abut against the side of the fixed block 100 , and the guide block 700 is used to limit the movement direction of the fixed block 100 .

[0051] Specifically, the guide block 700 is located on the side of the fixed block 100 . The guide block 700 contacts the fixed block 100 and plays a guiding role to ensure that the moving direction of the fixed block 100 is correct.

[0052] In an optional embodiment, the fixing block 100 is provided with a connecting groove 120 , one end of the elastic member 300 extends into the connecting groove 120 , and the end of the elastic member 300 extending into the connecting groove 120 is connected to the bottom of the connecting groove 120 .

[0053] Specifically, a connecting groove 120 is opened on a side of the fixed block 100 close to the position adjustment block 200, and the notch of the connecting groove 120 faces the position adjustment block 200. The elastic member 300 extends into the connecting groove 120. The connecting groove 120 partially wraps the elastic member 300, connecting the elastic member 300 while preventing the elastic member 300 from bending.

[0054] The other end of the elastic member 300 away from the fixed block 100 is connected to the end surface of the position adjustment block 200 facing the fixed block 100 .

[0055] In an optional embodiment, the fixing blocks 100 and the position adjustment blocks 200 are each provided in two groups, the two groups of fixing blocks 100 and the two groups of position adjustment blocks 200 are relatively arranged on both sides of the metal part 500, and the two groups of fixing blocks 100 and the two groups of position adjustment blocks 200 are symmetrically arranged on the mold body, and the metal part 500 is clamped using the two groups of fixing blocks 100 and the two groups of position adjustment blocks 200 respectively.

[0056] The mold positioning mechanism provided in this embodiment is achieved by slidingly installing a fixed block 100 and a position adjustment block 200 on the mold main body 400. The fixed block 100 and the position adjustment block 200 are connected by an elastic component 300. The elastic force generated by the elastic component 300 causes the fixed block 100 to have a movement tendency toward moving away from the position adjustment block 200. After the metal part 500 is pressed in, the elastic component 300 is in a compressed state, and the metal part 500 is clamped. After a period of time, the metal part 500 can be removed to observe or measure whether the metal part 500 is deformed. If deformed, the position adjustment block 200 can be adjusted backward to reduce the clamping force. If the metal part 500 is loose and falls, the position adjustment block 200 can be adjusted forward to increase the clamping force, thereby alleviating the technical problem that the traditional structure in the prior art directly presses the metal part 500 into the mold core, which is not only difficult to insert but also difficult to control the force, and easily deforms the metal part 500.

[0057] On the basis of the above embodiment, the overmolding mold provided in this embodiment includes a mold positioning mechanism.

[0058] Since the technical effect of the overmolding mold provided in this embodiment is the same as the technical effect of the mold positioning mechanism provided in the above embodiment, it will not be repeated here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
