Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a thermally conductive and insulating polyphenylene sulfide (PPS) demolding device. Background Technology

[0002] Polyphenylene sulfide (PPS) is a new type of high-performance thermoplastic resin with advantages such as high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties. It has wide applications in the electronics, automotive, machinery, and chemical industries. In the processing of PPS, it requires heating and molding using molds.

[0003] Existing technologies, such as the thermally conductive and insulating polyphenylene sulfide (PPS) demolding device disclosed in CN221436937U, include a base, four guide support rods fixed at the top corners of the base, with an upper mold base fixed at their top ends, a lower mold base slidably mounted on the support rods, a molding block fixed at the center of the top surface of the lower mold base, an adaptable molding cavity opened on the bottom surface of the upper mold base, an installation groove provided on the bottom surface of the lower mold base containing a movable seat, sliding rods at both ends of the top surface of the lower mold base, a sliding hole opened on the top surface of the lower mold base, and an abutment rod fixed at the corresponding position in the center of the movable seat on the bottom surface of the base. This allows for convenient demolding and improves the efficiency of the device.

[0004] However, this technical solution has the following problems in practical use:

[0005] The upper mold base is fixed to the top of four support rods. The lower mold base has a corresponding sliding hole on its top surface, with the end of the sliding rod extending out of the top surface of the upper mold base. During demolding, the sliding rod and the sliding hole guide the smooth ejection of the part. However, since the upper mold base lacks an ejection mechanism, when the sliding rod pushes the molded part upwards, the part is prone to sticking to the molding cavity of the upper mold base due to demolding resistance. This requires additional external force for a secondary operation, increasing working time and operational complexity, and affecting production efficiency. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art where the upper mold base does not have an ejection mechanism, and when the sliding rod pushes the molded part upward, the part is prone to sticking to the upper mold base molding cavity due to demolding resistance, requiring additional external force to perform a secondary operation. Therefore, a thermally conductive and insulating polyphenylene sulfide (PPS) demolding device is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A thermally conductive and insulating polyphenylene sulfide (PPS) demolding device includes a base, a top plate fixedly mounted on the top of the base, a bidirectional lead screw 1 rotatably connected to the opposite side walls of the top plate and the base, a movable mold base 1 and a movable mold base 2 respectively threaded onto the bidirectional lead screw 1, a motor 1 for driving the bidirectional lead screw 1 to rotate fixedly connected to the top of the top plate, and semi-circular openings provided on the opposite side walls of the movable mold base 1 and the movable mold base 2, with limit posts horizontally slidably inserted into the semi-circular openings;

[0009] Also includes:

[0010] A synchronization component is disposed on the base, and the synchronization component drives the two limiting columns to move synchronously relative to each other or in opposite directions.

[0011] Preferably, a pair of support rods are fixedly connected to the opposite sidewalls of the base and the top plate, and both the first moving mold base and the second moving mold base are vertically slidably connected to the support rods.

[0012] Preferably, the synchronization component includes a pair of Z-shaped plates fixedly mounted on the base, the two Z-shaped plates are rotatably connected to the same bidirectional lead screw II on opposite sidewalls, the bidirectional lead screw II is threaded with a pair of movable plates, and the movable plates are fixedly connected to the limiting post.

[0013] Preferably, a second motor for driving the second bidirectional lead screw to rotate is fixedly connected to the Z-shaped plate.

[0014] Preferably, the Z-shaped plate has a sliding groove, and the moving plate and the sliding groove are horizontally slidably connected.

[0015] Preferably, the limiting post and the semi-circular opening are adapted to each other, and the limiting post is correspondingly provided with the first moving mold base and the second moving mold base.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] This invention, through the setting of a synchronous component, allows the motor to drive the bidirectional lead screw to reverse after the PPS material is poured and cooled. This reverses the motor, causing the moving mold base one and the moving mold base two to separate in opposite directions along the support rod until the molded part is fully exposed and securely held in the air by the double limiting columns. After the operator places the receiving tool below, the moving plate drives the two limiting columns to slide synchronously in opposite directions, releasing the constraint on the molded part, achieving non-destructive demolding, improving the demolding success rate, and shortening the overall demolding operation time.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-3 A thermally conductive and insulating polyphenylene sulfide (PPS) demolding device includes a base 1, a top plate 5 fixedly mounted above the base 1, and a bidirectional lead screw 6 rotatably connected to the opposite sidewalls of the top plate 5 and the base 1. A movable mold base 2 and a movable mold base 3 are threadedly connected to the bidirectional lead screw 6. Under the action of the bidirectional lead screw 6, the movable mold base 2 and the movable mold base 3 move in opposite directions, and their positions are separated from the molded parts. A motor 7 for driving the bidirectional lead screw 6 is fixedly connected to the top of the top plate 5. Semi-circular openings 9 are provided on the opposite sidewalls of the movable mold bases 2 and 3. The semi-circular openings 9 are designed to facilitate the insertion of limiting posts 8, which clamp and fix the molded parts after insertion. The limiting posts 8 are horizontally slidably inserted into the semi-circular openings 9.

[0027] Also includes:

[0028] The synchronization component is set on the base 1 and drives the two limit posts 8 to move synchronously relative to each other or in opposite directions.

[0029] A pair of support rods 4 are fixedly connected to the opposite side walls of the base 1 and the top plate 5, and both the moving mold base 1 2 and the moving mold base 2 3 are vertically slidably connected to the support rods 4. The support rods 4 not only provide support for the top plate 5, but also ensure that the moving mold base 1 2 and the moving mold base 2 3 can move stably vertically along the axis of the bidirectional lead screw 6.

[0030] The synchronization assembly includes a pair of Z-shaped plates 81 fixedly mounted on the base 1. The two Z-shaped plates 81 are rotatably connected to the same bidirectional lead screw 82 on their opposite sidewalls. A pair of movable plates 84 are threaded onto the bidirectional lead screw 82, and the movable plates 84 are fixedly connected to the limiting posts 8. After the bidirectional lead screw 82 rotates, it drives the two movable plates 84 to move in opposite directions, causing the two limiting posts 8 to loosen their clamping and fixing of the molded part.

[0031] A motor 83 for driving the bidirectional lead screw 82 is fixedly connected to the Z-shaped plate 81.

[0032] The Z-shaped plate 81 has a sliding groove 85, and the movable plate 84 and the sliding groove 85 are horizontally slidably connected.

[0033] The limiting post 8 and the semi-circular opening 9 are compatible, and the limiting post 8 is correspondingly set with the moving mold base 1 2 and the moving mold base 2 3. The end of the limiting post 8 away from the moving plate 84 is flush with the inner wall of the moving mold base 1 2 and the moving mold base 2 3, in order to ensure the integrity of the part molding.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] First, start motor 7 to drive the bidirectional lead screw 6 to rotate, causing the moving mold base 2 and the moving mold base 3 to move relative to each other along the support rod 4 until they close. At this time, the two semi-circular openings 9 are joined together to form a complete circular hole, and the limiting post 8 is horizontally inserted into the circular hole.

[0036] When casting and demolding are performed after cooling, start motor 7 to drive the bidirectional lead screw 6 to rotate in the opposite direction, causing the moving mold base 2 and the moving mold base 3 to move in opposite directions along the support rod 4 until the entire molded part is fully exposed. At this time, the part is suspended in the air by two limit posts 8.

[0037] Subsequently, after placing a tool below to support the component, start motor 83, which drives the bidirectional lead screw 82 to rotate, causing a pair of movable plates 84 threaded onto it to move synchronously in opposite directions along the slide groove 85, thereby pushing the two limit posts 8 away from the component, loosening the clamping and fixing of the component, and thus removing the molded component.

[0038] Throughout the process, the synchronous drive of the two-way lead screw 16 and the two-way lead screw 282 ensures the movement of the moving mold base 12, the moving mold base 23 and the limiting post 8, guaranteeing the stability and completeness of demolding, and improving the production efficiency and quality of thermally conductive and insulating PPS products.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
