Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a special slide-position secondary core-pulling parting mold. Background Technology

[0002] A delayed core-pulling mechanism, also known as a secondary core-pulling mechanism, is used on the slide of an injection mold. The original slide structure has a single action and can only pull the core once, which is not suitable for products with more complex structures. At the same time, during core pulling, it is easy to cause the injection molded part to stick to the slide seat. Utility Model Content

[0003] The purpose of this utility model is to provide a special sliding secondary core-pulling parting mold to solve the technical problems existing in the prior art where the secondary core-pulling structure can only cast relatively simple injection molded parts, and the injection molded parts are prone to adhesion to the sliding seat. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides a special sliding secondary core-pulling parting mold, including a support frame, a first sliding seat, a second sliding seat, a third sliding seat, sliding inserts, and a driving assembly symmetrically arranged on the support frame;

[0006] The second row seat and the third row seat are combined together by a first fastener, and one end of the row insert is mounted on the second row seat. The first row seat and the second row seat are provided with a first through hole for the row insert to pass through. The row insert passes through the first through hole and connects to form a core.

[0007] The first row seat is provided with a second through hole, and a first step is provided in the second through hole. The second fastener passes through the second through hole and is fixed on the second row seat. The end of the second fastener can abut against the first step so that the third row seat can drive the first row seat to move.

[0008] The driving component is connected to the third row seat, and the driving component drives the third row seat to move so as to disengage the row insert from the injection molded workpiece.

[0009] Preferably, the device further includes a rear mold insert, the rear mold insert having a first protrusion and a second protrusion at both ends. The side of the second protrusion away from the first protrusion abuts against the first slide seat to limit the first slide seat. The third slide seat has a first sliding groove that mates with the first protrusion, and the second slide seat has a second sliding groove that mates with the second protrusion. The end of the first sliding groove near the second sliding groove is set as a first inclined surface, and the side of the first protrusion near the second protrusion is set as a second inclined surface that mates with the first inclined surface. An elastic element is provided between the rear mold insert and the support frame. When the first inclined surface abuts against the second inclined surface, the rear mold insert can be moved away from the third slide seat, so that the height of the second protrusion is lower than the bottom of the first slide seat, and the first slide seat is moved by the second fastener.

[0010] Preferably, the support frame is provided with a connecting rod, the elastic element is sleeved on the connecting rod, and the two ends of the elastic element abut against the support frame and the rear mold insert, respectively.

[0011] Preferably, it further includes a first guide post, and the first row seat, the second row seat, and the third row seat are all provided with a third sliding groove that cooperates with the first guide post, and the first guide post is fixed in the third sliding groove on the first row seat.

[0012] Preferably, the drive assembly includes an inclined column and an inclined hole, the inclined hole being disposed on the support frame and the third row seat, and the inclined column passing through the support frame, the third row seat, and the inclined hole on the support frame in sequence.

[0013] Preferably, it also includes a pressure plate, and the first row seat, the second row seat, and the third row seat are provided with second steps on both sides along the direction of movement. The pressure plate is pressed on the second steps and the pressure plate is fixed on the support frame.

[0014] Preferably, the first row seat has a third inclined surface at one end near the second protrusion, and the position of the third inclined surface corresponds to the position of the second protrusion.

[0015] Preferably, one of the second row seat and the first row seat is provided with a limiting protrusion, and the other is provided with a limiting groove, wherein the limiting groove matches the limiting protrusion.

[0016] The technical solution provided in this application document has the following beneficial effects:

[0017] This utility model provides a special secondary core-pulling parting mold with a special slide position, including a support frame, a first slide seat, a second slide seat, a third slide seat, slide inserts, and a drive assembly symmetrically arranged on the support frame. That is, two sets are symmetrically arranged on the support frame, each set including a first slide seat, a second slide seat, a third slide seat, slide inserts, and a drive assembly, which facilitates core pulling at both ends, thereby forming a secondary core-pulling structure.

[0018] The second and third row seats are combined together by a first fastener. When the third row seat moves, it drives the second row seat. Since one end of the row insert is installed on the second row seat, the movement of the second row seat drives the movement of the row insert. The first and second row seats are provided with a first through hole for the row insert to pass through. The row insert passes through the first through hole and connects to form a core. The support frame is provided with an outer wall, and a space for liquid to pass through is formed between the outer wall and the core. In this way, the injection molded part generates the required structure according to the shape of the space.

[0019] To facilitate the movement of the first row seat, a second through hole is provided on the first row seat, and a first step is provided inside the second through hole. A second fastener passes through the second through hole and is fixed on the second row seat, and the end of the second fastener can abut against the first step, so that the third row seat can drive the first row seat to move, thereby separating the first row seat from the injection molded part.

[0020] To facilitate the movement of the third row seat, the drive assembly is connected to the third row seat, and the drive assembly drives the third row seat to move so as to disengage the drive insert from the injection molded workpiece.

[0021] With this configuration, since there are two sets of slide inserts, core pulling can be performed at both ends, which facilitates the processing of more complex workpieces. At the same time, since there is a second connector, the second connector drives the first slide seat to move, thus solving the problem of injection molded parts sticking to the slide seat.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] This specific embodiment provides a special slide secondary core-pulling parting mold, which solves the technical problem that the secondary core-pulling structure in the prior art can only cast injection molded parts with relatively simple structures, and that the injection molded parts are prone to sticking to the slide seat.

[0034] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0035] Reference Figures 1-8 This utility model provides a special secondary core-pulling parting mold with a special slide position, including a support frame 10, a first slide seat 1, a second slide seat 2, a third slide seat 3 symmetrically arranged on the support frame 10, slide inserts, and a drive assembly 6. That is, two sets are symmetrically arranged on the support frame 10, each set including the first slide seat 1, the second slide seat 2, the third slide seat 3, the slide inserts 5, and the drive assembly 6, which facilitates core pulling at both ends.

[0036] The second row seat 2 and the third row seat 3 are combined together by a first fastener. When the third row seat 3 moves, it drives the second row seat 2. Since one end of the row insert 5 is installed on the second row seat 2, the movement of the second row seat 2 drives the movement of the row insert 5. The first row seat 1 and the second row seat 2 are provided with a first through hole for the row insert 5 to pass through. The row insert 5 passes through the first through hole and connects to form a core. The specific support frame is provided with an outer wall. A space for liquid to pass through is formed between the outer wall and the core. In this way, the injection molded part generates the required structure according to the shape of the space.

[0037] To facilitate the movement of the first row seat 1, a second through hole 13 is provided on the first row seat 1, and a first step is provided inside the second through hole 13. The second fastener 11 passes through the second through hole 13 and is fixed on the second row seat 2, and the end of the second fastener 11 can abut against the first step, so that the third row seat 3 can drive the first row seat 1 to move, thereby separating the first row seat 1 from the injection molded part.

[0038] To facilitate the movement of the third row seat 3, the drive assembly 6 is connected to the third row seat 3. The drive assembly 6 drives the third row seat 3 to move so as to disengage the drive insert 5 from the injection molded workpiece.

[0039] With this configuration, since there are two sets of slide inserts 5, core pulling can be performed at both ends, which facilitates the processing of more complex workpieces. At the same time, since there is a second connector, the second connector drives the first slide seat 1 to move, thus solving the problem of injection molded parts sticking to the slide seat.

[0040] To further optimize the design and prevent the first row seat from initially moving with the third row seat 3, a rear mold insert 4 is also included. The upper surface of the rear mold insert 4 has a first protrusion 41 and a second protrusion 42 at both ends. The third row seat 3 has a first sliding groove 31 that mates with the first protrusion 41, and the second row seat 2 has a second sliding groove 21 that mates with the second protrusion 42. The end of the first sliding groove 31 closest to the second sliding groove 21 is configured as a first inclined surface 311, and the side of the first protrusion 41 closest to the second protrusion 42 is configured as a second inclined surface 411 that mates with the first inclined surface 311. The side of the second protrusion 42 furthest from the first protrusion 41 is configured as a second inclined surface 411 that mates with the first inclined surface 311. The slide seat 1 abuts against each other to limit the first slide seat 1. An elastic member 7 is provided between the rear mold insert 4 and the support frame 10. When the first inclined surface 311 abuts against the second inclined surface 411, the rear mold insert 4 can be moved away from the third slide seat 3, so that the height of the second protrusion 42 is lower than the bottom of the first slide seat. At this time, the first slide seat 1 is moved by the second fastener 11. That is, the length of the first sliding groove is the same as the distance of the second fastener to the far east of the first slide seat. In this way, when the top of the second protrusion drops to be flush with the bottom of the second slide seat, the end of the second fastener just abuts against the first step on the first slide seat 1, causing the first slide seat to move away from the injection molded part.

[0041] To further optimize the design, in order to ensure that the elastic element can move straight up and down, a connecting rod 102 is provided on the support frame 10. The elastic element 7 is sleeved on the connecting rod 102, and the two ends of the elastic element 7 abut against the support frame 10 and the rear mold insert 4 respectively. The connecting rod 102 plays a guiding role.

[0042] To further optimize the design and reduce the swaying of the second row seat 2 and the third row seat 3, a first guide post 9 is also included. The first row seat 1, the second row seat 2, and the third row seat 3 are provided with a third sliding groove 101 on both sides that cooperates with the first guide post 9. The first guide post 9 is fixed in the third sliding groove 101 on the first row seat 1 to ensure that the first row seat 1, the second row seat 2, and the third row seat 3 can move in a straight line.

[0043] Further optimizing the scheme, the drive component 6 includes an inclined column 61 and an inclined hole 62. The inclined hole 62 is set on the support frame 10 and the third row seat 3. The inclined column 61 passes through the support frame 10, the third row seat 3, and the inclined hole 62 on the support frame 10 in sequence. When the inclined column 61 moves upward, it can cause the third row seat 3 to move away from the injection molded part, so that the row insert 5 is disengaged from the injection molded part. When the inclined column 61 moves downward, it drives the third row seat 3 to move closer to the injection molded part, so that the two row inserts 5 abut against each other, which facilitates the injection of the molded part.

[0044] To further optimize the scheme and prevent the first row seat 1, the second row seat 2, and the third row seat from rising, a pressure plate 8 is also included. The first row seat 1, the second row seat 2, and the third row seat 3 are provided with second steps on both sides along the direction of movement. The pressure plate 8 is pressed on the second steps and is fixed to the support frame 10.

[0045] To further optimize the design, in order to facilitate the smooth movement of the first row seat 1 away from the injection molded part, a third inclined surface 12 is provided at the end of the first row seat 1 near the second protrusion 42. The position of the third inclined surface 12 corresponds to the position of the second protrusion 42, so that the first row seat can pass over the second protrusion 42.

[0046] To further optimize the design, one of the second row seat 2 and the third row seat 3 is provided with a limiting protrusion 32, and the other is provided with a limiting groove 22. The limiting groove 22 matches the limiting protrusion 32, thus ensuring that the end faces of the second row seat 2 and the third row seat 3 are flush.
