Description

Technical Field

[0001] The present invention relates to the field of mold technology, and in particular to a mold and an injection molding machine. Background Technology

[0002] Plastic parts are generally formed by molds. For plastic parts with hollow structures, a molding part needs to be placed in the mold to fill the cavity of the plastic part. After the plastic part is formed in the mold, the molding part is first extracted from the cavity of the plastic part, and then the plastic part is removed from the mold.

[0003] For some plastic parts with cavities, when the area of ​​the cavity opening is smaller than the area of ​​the cavity bottom, the molded part includes at least a first filling part and a second filling part. After the plastic part is molded in the mold, the first filling part needs to be extracted from the cavity along the first direction, and then the second filling part needs to be moved along the second direction to a position where the cavity opening allows the second filling part to pass through. Then the second filling part is extracted from the cavity along the first direction, and finally the plastic part is taken out of the mold.

[0004] In the implementation of this invention, the inventors discovered that when the area of ​​the cavity opening of the plastic part is smaller than the area of ​​the cavity bottom of the plastic part, at least two cylinders are generally used to drive the movement of the second filling part. One cylinder is used to drive the second filling part to move along the second direction, and the other cylinder is used to drive the second filling part to move along the first direction. Furthermore, an algorithm is needed to control one cylinder to first drive the second filling part to move along the second direction to a position where the cavity opening allows the second filling part to pass through, and then control the other cylinder to drive the second filling part to move along the first direction to a position where the second filling part separates from the cavity of the plastic part. Summary of the Invention

[0005] The main technical problem solved by the embodiments of the present invention is to provide a mold and an injection molding machine that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this embodiment of the invention is: providing a mold, including a first mold body, a second mold body assembly, a cavity forming module, and a limiting rod. The first mold body is provided with a first cavity; the second mold body assembly is provided with a second cavity, a first movable groove, and a limiting groove. When the first mold body and the second mold body assembly are closed, the first cavity and the second cavity together form a finished product cavity. The first movable groove communicates with the finished product cavity, and the limiting groove is disposed at the bottom of the first movable groove, and the limiting groove is inclined away from the first sidewall of the finished product cavity. The cavity forming module includes a first forming component, a second forming component, a guide component, a connector, and a first driving component. The guide component and the first driving component are slidably disposed in a first movable groove. The two ends of the connector are respectively connected to the first driving component and the guide component. The guide component is provided with an insertion groove and a through groove.

The insertion groove is located above the limiting groove, and one end of the limiting rod is inserted into the limiting groove to restrict the movement of the guide assembly in the first direction. When the first driving member moves from the first preset position to the second preset position, under the combined action of the first sliding structure, the second sliding structure, and the guide assembly, the second molded part moves in the second direction, which is perpendicular to the first direction. The clearance groove moves to the top of the insertion groove, allowing one end of the limiting rod to slide along the first side wall so that the other end of the limiting rod is received in the clearance groove, thereby releasing the restriction on the guide assembly. When the first driving member moves from the second preset position to the third preset position, under the action of the connecting member, the guide assembly drives the second molded part to move in the first direction until the second molded part leaves the finished product cavity.

[0007] Optionally, the guiding component is further provided with a guiding groove, which is connected to the side wall of the through groove perpendicular to the bottom of the first movable groove, and the center line of the guiding groove is parallel to the second direction; the second molded part is provided with a guiding part, which is slidably engaged with the guiding groove.

[0010] Optionally, the second mold assembly includes a second mold body, a mounting base, a first fixing strip, and a second fixing strip. The second cavity is disposed in the second mold body, and the second mold body is fixed to the mounting base. The second mold body and the mounting base together form the first movable groove. The first fixing strip and the second fixing strip are both mounted on the mounting base. The first fixing strip protrudes from the second sidewall of the first movable groove, so that the first fixing strip, the second sidewall, and the bottom of the first movable groove together form a first guide groove. The second fixing strip protrudes from the third sidewall of the first movable groove, so that the second fixing strip, the third sidewall, and the bottom of the first movable groove together form a second guide groove. The second sidewall and the third sidewall are opposite to each other. The first driving member is further provided with a first slide and a second slide. The first slide is slidably disposed in the first guide groove, and the second slide is slidably disposed in the second guide groove.

[0011] Optionally, the guide assembly is provided with a third slide and a fourth slide, the third slide being slidably disposed in the first guide groove, and the fourth slide being slidably disposed in the second guide groove.

[0012] Optionally, the second mold assembly is further provided with a second movable groove, which communicates with the finished product cavity; the mold also includes a filling module, which includes a second driving member and a third molding member, the second driving member being slidably disposed in the second movable groove, and one end of the third molding member being fixed to the second driving member; when the second driving member is in a fourth preset position, the other end of the third molding member is received in the finished product cavity, and when the second driving member moves to a fifth preset position, the third molding member separates from the finished product cavity.

[0015] To solve the above-mentioned technical problems, another technical solution adopted in the embodiments of the present invention is to provide an injection molding machine, including the above-mentioned mold.

[0016] The beneficial effects of this invention are as follows: Unlike existing technologies, this invention provides a first cavity in a first mold body, and a second cavity, a first movable groove, and a limiting groove in a second mold body assembly. The limiting groove has an inclined first sidewall. When the first and second mold bodies are closed, the first and second cavities together form the finished product cavity. A first driving member is slidably disposed in the first movable groove, and a first molding member is fixed to the first driving member. The first molding member has a first sliding structure, and the second molding member has a second sliding structure. The first and second sliding structures are slidably engaged. The second molding member is slidably disposed in a guide assembly, and the sliding direction of the second molding member in the guide assembly is perpendicular to the sliding direction of the first driving member in the first movable groove. When the first driving member is in a first preset position, the first and second molding members are partially housed in the finished product cavity. An insertion groove is located above the limiting groove, and one end of a limiting rod is inserted into the limiting groove to restrict the guide assembly and the second molding member from moving along the first... Directional movement; when the first driving member moves from the first preset position to the second preset position along the first direction, under the combined action of the first molding member and the guide assembly, the second molding member moves along the second direction. When the first driving member is in the second preset position, the clearance groove of the first molding member is located above the insertion groove of the guide assembly. At this time, one end of the limiting rod is allowed to slide along the first side wall so that the limiting rod can move along the insertion groove until the other end of the limiting rod is received in the clearance groove, thereby releasing the limitation on the guide assembly. When the first driving member moves from the second preset position to the third preset position, under the action of the connecting member, the guide assembly drives the second molding member to move along the first direction to the position where the second molding member leaves the finished product cavity. The first molding member can be extracted from the finished product cavity simply by the first driving member moving along the first direction. At the same time, the second molding member moves first along the second direction and then along the first direction. There is no need to set up two additional cylinders, and there is no need to set up a program to control the movement of the two cylinders, which is beneficial to saving energy.

The guide portion 3052 is inserted into the guide groove 3023 and can slide along the guide groove 3023, thereby allowing the second molded part 305 to reciprocate only in the second direction relative to the guide assembly 302. The second sliding structure 3051 is disposed on the surface of the second molded part 305 facing the first molded part 304, and the first sliding structure 3042 and the second sliding structure 3051 are slidably engaged. When the first driving member 301 is in the first preset position, please refer to... Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 14 and Figure 18 The other end of the first molding part 304 and the other end of the second molding part 305 are both received in the finished product cavity 9, and there is a gap between the other end of the first molding part 304 and the other end of the second molding part 305 and the inner wall of the finished product cavity 9, so that the raw material can fill the gap to form the product 200. The insertion groove 3021 of the guide component 302 is located above the limiting groove 208. One end of the limiting rod 4 is inserted into the limiting groove 208. The first molding part 304 covers the end of the insertion groove 3021 away from the limiting groove 208, thereby restricting the movement of the limiting rod 4 along the insertion groove 3021 and preventing one end of the limiting rod 4 from leaving the limiting groove 208, thereby restricting the movement of the guide component 302 in the first direction. It should be noted that the other end of the first molding component 304 and the other end of the second molding component are both away from the first driving component 301. The first molding component 304 and the second molding component 305 are used together to form the first cavity 2001 of the product 200. When the first driving component 301 moves from the first preset position to the second preset position along the first direction, Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18The first molded part 304 moves along the first direction. Under the combined action of the first sliding structure 3042, the second sliding structure 3051, the guide part 3052, the guide assembly 302, and the limiting rod 4, the second molded part 305 moves along the second direction to a position where the other end of the second molded part 305 can pass through the opening of the first cavity 2001 of the product 200. When the first driving member 301 is in the second preset position, the clearance groove 3041 of the first molded part 304 is located above the insertion groove 3021. At this time, the limiting rod 4 is allowed to move away from the limiting groove 208 to release the limiting of the guide assembly 302. At the same time, the protrusion 3031 of the connecting member 303 abuts against the bottom of the first receiving groove 3012. When the first driving member 301 moves from the second preset position to the third preset position along the first direction, please refer to... Figures 19 to 21 One end of the limiting rod 4 slides away from the limiting groove 208 along the first side wall 2081 of the limiting groove 208, so that the other end of the limiting rod 4 is received in the clearance groove 3041. The first side wall 2081 is away from the finished product cavity 9. Under the action of the connecting member 303, the guiding component 302 and the second molding member 305 move along the first direction to a position where the other end of the second molding member 305 is completely separated from the product 200 in the finished product cavity 9. By fixing the first molding member 304 and the first driving member 301, the second molding member 305 cooperates with the first sliding structure 3042 of the first molding member 304 through the second sliding structure 3051. At the same time, the movement of the second molding member 305 is restricted by the guiding component 302 and the limiting rod 4. This achieves the goal that when the first driving member 301 moves along the first direction, the second molding member 305 can move along the second direction first and then along the first direction. There is no need to set up two cylinders to drive the movement of the second molding member 305, which helps to simplify the structure of the mold 100. It is worth noting that the first sidewall 2081 is inclined, and one end of the limiting rod 4 is provided with a first inclined surface 401. The first inclined surface 401 is used to cooperate with the first sidewall 2081, so that when the guide component 302 moves along the first direction, one end of the limiting rod 4 slides away from the limiting groove 208 along the first sidewall 2081.

[0053] In some embodiments, please refer to Figure 15 The first sliding structure 3042 is a sliding boss, and the second sliding structure 3051 is a sliding groove, wherein the sliding boss and the sliding groove are in sliding engagement.

[0054] In some embodiments, please refer to Figure 12The cavity forming module 3 further includes a guide assembly 306, which includes a guide rod 3061 and an elastic element 3062. The first driving member 301 is also provided with a guide hole 3016 and a second receiving groove 3017. The second receiving groove 3017 is disposed on the surface of the first driving member 301 facing the guide assembly 302. The guide hole 3016 communicates with the bottom of the second receiving groove 3017. One end of the guide rod 3061 is fixed to the guide assembly 302, and the other end of the guide rod 3061 passes through the second receiving groove 3017 and the guide hole 3016 in sequence. The guide rod 3061 is slidable relative to the first driving member 301. The elastic element 3062 is sleeved on the guide rod 3061, and the elastic element 3062 is partially received in the second receiving groove 3017. When the first driving member 301 is in the first preset position, one end of the elastic element 3062 abuts against the bottom of the second receiving groove 3017, and the other end of the elastic element 3062 abuts against the surface of the guide component 302 facing the first driving member 301, so that when the first driving member 301 moves to the first preset position in the opposite direction of the first direction, the elastic element 3062 can push the guide component 302 to move, thereby allowing the second molding member 305 to move to the position where the other end of the second molding member 305 is received in the finished product cavity 9.

[0055] In some embodiments, please refer to Figure 7 , Figure 14 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 and Figure 21 The other end of the limiting rod 4 is provided with a second inclined surface 402, and the clearance groove 3041 has an inclined sixth side wall 30411. The sixth side wall 30411 is away from the finished product cavity 9, and the sixth side wall 30411 cooperates with the second inclined surface 402. When the first driving member 301 moves from the third preset position to the second preset position, under the action of the elastic member 3062, the guiding component 302 moves in the opposite direction of the first direction to the position where the guiding component 302 abuts against the second mold body 201, and at this time the insertion groove 3021 communicates with the limiting groove 208; when the first driving member 301 moves from the second preset position to the first preset position, under the action of the sixth side wall 30411 and the second inclined surface 402, the other end of the limiting rod 4 slides away from the clearance groove 3041 along the sixth side wall 30411, and one end of the limiting rod 4 gradually inserts into the limiting groove 208. At this time, the limiting rod 4 prevents the guiding component 302 from moving in the first direction.

[0056] For the filling module 5 mentioned above, please refer to... Figure 1 , Figure 3 and Figure 7 The filling module 5 includes a second driving member 501, a third forming member 502, and a screw connector 503. The second driving member 501 is slidably disposed in the second movable groove 211. One end of the third forming member 502 is fixed to the second driving member 501 by the screw connector 503. The other end of the third forming member 502 is used to form the second cavity 2002 of the product 200. The other end of the second driving rod 7 is connected to the second driving member 501 and is used to drive the second driving member 501 to move.

[0057] For the second drive unit 501 mentioned above, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 9 The second driving member 501 is provided with a second screw hole 5011, a snap-fit ​​groove 5012, a second driving hole 5013, a fifth slide 5014, and a sixth slide 5015. The second screw hole 5011 is located at the bottom of the snap-fit ​​groove 5012. The fifth slide 5014 and the sixth slide 5015 are opposite to each other, and the fifth slide 5014 is slidably engaged with the third guide groove 2051, and the sixth slide 5015 is slidably engaged with the fourth guide groove 2052, so that the second driving member 501 can only move along the third guide groove 2051 and the fourth guide groove 2052. From one end of the second drive hole 5013 near the bottom of the second movable groove 211 to the other end of the second drive hole 5013 away from the bottom of the second movable groove 211, the distance between the second drive hole 5013 and the finished product cavity 9 becomes smaller and smaller. The other end of the second drive rod 7 is inserted into the second drive hole 5013. When the first mold body 1 moves away from the second mold body 201, under the combined action of the first drive rod 6, the first drive hole 3015, the fifth slide 5014, the third guide groove 2051, the sixth slide 5015 and the fourth guide groove 2052, the second drive member 501 moves away from the finished product cavity 9.

[0058] For the third molded part 502 mentioned above, please refer to... Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 9The third molded part 502 has a snap-fit ​​portion 5022 at one end, which snaps into the snap-fit ​​groove 5012, so that the second driving member 501 can drive the third molded part 502 to move. The third molded part 502 also has a second through hole 5021, which passes through the snap-fit ​​portion 5022. The screw member 503 passes through the second through hole 5021 and is screwed into the second screw hole 5011 to prevent the snap-fit ​​portion 5022 from separating from the snap-fit ​​groove 5012. When the second driving member 501 is in the fourth preset position, the other end of the third molding member 502 is received in the finished product cavity 9, and there is a gap between the other end of the third molding member 502 and the inner wall of the finished product cavity 9 for raw materials to fill, so as to form the second cavity 2002 of the product 200; when the second driving member 501 moves from the fourth preset position to the fifth preset position, the second driving member 501 drives the third molding member 502 to a position where the other end of the third molding member 502 is separated from the finished product cavity 9. Through the second driving rod 7 and the second driving hole 5013, when the mold is opened, moving the first mold body 1 in a direction away from the second mold body 201 can drive the second driving member 501 to move, thereby driving the third molding member 502 away from the finished product cavity 9. There is no need to set up an additional cylinder or motor, which helps to save energy and simplifies the structure.

[0059] In some embodiments, the movement directions of the second driving member 501 and the third molding member 502 are parallel to the second direction.

[0060] In this embodiment of the invention, a first cavity 101 is provided in the first mold body 1, and a second cavity 2011, a first movable groove 207, and a limiting groove 208 are provided in the second mold body assembly 2. The limiting groove 208 has an inclined first sidewall 2081. When the first mold body 1 and the second mold body 201 are closed, the first cavity 101 and the second cavity 2011 together form the finished product cavity 9. The first driving member 301 is slidably disposed in the first movable groove 207, and the first molding member 304 is fixed to the first driving member 301. The first molding member 304 is provided with a first sliding structure 3042, and the second molding member 305 is provided with a second sliding structure 3042. The sliding structure 3051, the first sliding structure 3042, and the second sliding structure 3051 are slidably engaged. The second molded part 305 is slidably disposed on the guide assembly 302, and the sliding direction of the second molded part 305 on the guide assembly 302 is perpendicular to the sliding direction of the first driving member 301 in the first movable groove 207. When the first driving member 301 is in the first preset position, the first molded part 304 and the second molded part 305 are partially housed in the finished product cavity 9. The insertion groove 3021 is located above the limiting groove 208, and one end of the limiting rod 4 is inserted into the limiting groove 208 to limit the guide assembly 302 and... The second molded part 305 moves along the first direction; when the first driving member 301 moves from the first preset position to the second preset position along the first direction, under the combined action of the first molded part 304 and the guide assembly 302, the second molded part 305 moves along the second direction, and when the first driving member 301 is in the second preset position, the clearance groove 3041 of the first molded part 304 is located above the insertion groove 3021 of the guide assembly 302. At this time, one end of the limiting rod 4 is allowed to slide along the first side wall 2081, so that the limiting rod 4 can move along the insertion groove 3021 until the other end of the limiting rod 4 is received in the clearance groove 304. 1. This releases the limit on the guide component 302. When the first drive component moves from the second preset position to the third preset position, under the action of the connector 303, the guide component 302 drives the second molding component 305 to move along the first direction to the position where the second molding component 305 leaves the finished product cavity 9. The first molding component 304 can be extracted from the finished product cavity 9 simply by the first drive component 301 moving along the first direction. At the same time, the second molding component 305 moves first along the second direction and then along the first direction. There is no need to set up two additional cylinders, and there is no need to set up a program to control the movement of the two cylinders, which is conducive to saving energy.
