The automatic mold shaking device includes a base 1, a mold opening and closing mechanism 2 and a mold shaking drive mechanism 3, wherein the mold opening and closing mechanism 2 is provided with a mold for thermoplastic compression molding, and the amplitude and speed of the reciprocating movement of the mold shaking push plate 301 are adjusted and controlled by the drive component 302, so as to drive the mold opening and closing mechanism 2 to rotate around the axis, thereby realizing the precise and adjustable mold shaking amplitude and speed forward and backward. After shaking the mold, the mold can be reset to the flat mold state, the mold can be opened to take out the workpiece, which replaces the working method of manually shaking the mold in the prior art, which can not only effectively reduce labor intensity and save labor costs, but also has a high degree of automation and strong continuous working stability, and can effectively improve production efficiency and production quality.

[0029] Preferably, the rocking mold push plate 301 is slidably connected to the base 1 through a sliding connection mechanism 4, and the sliding connection mechanism 4 includes a slide rail 401 and a slider 402. The slide rail 401 is fixedly connected to the base 1, and the rocking mold push plate 301 is fixedly connected to a group of sliders 402. In this embodiment, the sliding connection mechanism 4 adopts the form of a slider 402 slidingly connected to the slide rail 401, which has the advantages of simple structure, convenient and fast installation and disassembly process, and good operation stability. Specifically, the slide rail 401 is arranged on the base 1 along the horizontal direction, that is, the rocking mold push plate 301 reciprocates along the horizontal direction to realize linear rocking.

[0030] Preferably, the driving assembly 302 is slidably connected to the base 1 through the sliding connection mechanism 4. The driving assembly 302 includes a first driving cylinder 3021 and a second driving cylinder 3022 arranged in opposite directions. The cylinder bodies of the first driving cylinder 3021 and the second driving cylinder 3022 are both fixedly connected to another group of sliders 402. The piston rod of the first driving cylinder 3021 is connected to the rocking mold push plate 301, and the piston rod of the second driving cylinder 3022 is connected to the base 1. In this embodiment, the cylinder bodies of the first driving cylinder 3021 and the second driving cylinder 3022 are both fixedly connected to the same group of sliders 402, that is, the first driving cylinder 3021 and the second driving cylinder 3022 can move relative to the base 1. When the mold opening and closing mechanism 2 is in the rear rocking state (such as Figure 3 As shown in FIG. 2 ), the piston rods of the first driving cylinder 3021 and the second driving cylinder 3022 are both in an extended state, and when the mold opening and closing mechanism 2 is in a forward swing state (as shown in FIG. 2 ), the piston rods of the first driving cylinder 3021 and the second driving cylinder 3022 are both in an extended state. Figure 2As shown in the figure, the piston rods of the first driving cylinder 3021 and the second driving cylinder 3022 are both in a retracted state, and the rocking mold push plate 301 is reciprocated by the telescopic cooperation between the driving components 302, and the driving cylinders run along a straight line, which has good working stability and is conducive to extending the service life. In other embodiments, the driving component 302 can also use a component with a reciprocating movement function such as a gear rack transmission, a chain transmission, etc., which is not limited to this embodiment.

In this embodiment, the adjusting screw 5 is threadedly connected to the bottom of the mold swinging push plate 301, and the head of the adjusting screw 5 is used to abut against the end of the base 1. The rotation angle of the mold opening and closing mechanism 2 is adjusted by screwing the adjusting screw 5 in and out of the mold swinging push plate 301. Specifically, when the mold opening and closing mechanism 2 needs to be swung back at a larger angle (such as Figure 3 As shown), the adjusting screw 5 is screwed inward on the rocking mold push plate 301, and when the head of the adjusting screw 5 is in contact with the base 1, the distance between the rocking mold push plate 301 and the end of the base 1 is small, and the rotation angle of the opening and closing mold mechanism 2 is large; when the opening and closing mold mechanism 2 needs to be swung back at a smaller angle, the adjusting screw 5 is screwed outward on the rocking mold push plate 301, and when the head of the adjusting screw 5 is in contact with the base 1, the distance between the rocking mold push plate 301 and the end of the base 1 is large, and the rotation angle of the opening and closing mold mechanism 2 is small; in addition, the rotation angle of the opening and closing mold mechanism 2 can be adjusted by controlling the stroke of the first driving cylinder 3021 and the second driving cylinder 3022, and the front and rear rocking angles can be adjusted steplessly from 25° to 50°.

[0033] Preferably, the mold base 201 is connected to the rocking mold push plate 301 via a first sliding connection mechanism 6, and the first sliding connection mechanism 6 includes a first pin 601 provided on the mold base 201 and a first guide groove 602 provided on the rocking mold push plate 301, and the first pin 601 is provided through the first guide groove 602. In this embodiment, the first guide groove 602 on the rocking mold push plate 301 is provided along the vertical direction, and during the process of the mold opening and closing mechanism 2 rotating around the axis on the base 1, the first pin 601 on the mold base 201 moves up and down in the first guide groove 602. Specifically, when the mold opening and closing mechanism 2 is in the forward or backward rocking state (such as Figure 2 and Figure 3As shown in FIG. 1 ), the first pin 601 is located at the upper part of the first guide groove 602. When the mold opening and closing mechanism 2 is in the flat mold state (as shown in FIG. 1 ), the first pin 601 is located at the upper part of the first guide groove 602. Figure 1 As shown in FIG. 6A ), the first pin shaft 601 is located at the lower part of the first guide groove 602 .

[0034] Preferably, the rocker arm driving assembly 204 includes a first rocker arm 2041, a second rocker arm 2042, a pressing arm 2043, an upper mold pull rod 2044 and a third driving cylinder 2045, the pressing arm 2043 is hingedly connected to the mold base 201, the first rocker arm 2041 is hingedly connected to the mold base 201, one end of the first rocker arm 2041 is hingedly connected to the piston rod of the third driving cylinder 2045, the other end of the first rocker arm 2041 is hingedly connected to one end of the second rocker arm 2042, the other end of the second rocker arm 2042 is hingedly connected to the pressing arm 2043, one end of the upper mold pull rod 2044 is connected to the pressing arm 2043, and the other end of the upper mold pull rod 2044 is hingedly connected to the upper mold 203. In this embodiment, as Figure 4 As shown, the cylinder body of the third driving cylinder 2045 is hingedly connected to the mold base 201, and the extension and retraction of the piston rod of the third driving cylinder 2045 drives the first rocker arm 2041 to rotate around the axis on the mold base 201, thereby driving the second rocker arm 2042 to rotate around the axis on the pressure arm 2043, and then driving the pressure arm 2043 to rotate around the axis on the mold base 201, and finally driving the upper mold 203 to rotate around the axis on the lower mold 202 to complete mold opening or mold closing; when the upper mold 203 and the lower mold 202 are in the mold closing state (combined with Figure 1 and Figure 7 As shown in the figure), the hinge point between the mold base 201 and the pressure arm 2043, the hinge point between the second rocker arm 2042 and the pressure arm 2043, and the hinge point between the first rocker arm 2041 and the second rocker arm 2042 form a 90° angle, which can achieve unpowered self-locking, that is, when the third driving cylinder 2045 is unpowered, even if the opening and closing mold mechanism 2 performs the forward and backward rocking process on the base 1, the upper mold 203 and the lower mold 202 are always in the mold closing state.

[0035] Preferably, the upper mold pull rod 2044 is connected to the pressure arm 2043 via a second sliding connection mechanism 7, which includes a second pin shaft 701 arranged on the upper mold pull rod 2044 and a second guide groove 702 arranged on the pressure arm 2043, and the second pin shaft 701 is arranged through the second guide groove 702.

[0036] Preferably, the pressing arm 2043 is provided with a limiting protrusion 8 for contacting with the second rocker arm 2042. Figure 7As shown, a limiting protrusion 8 is provided on the pressing arm 2043. When the upper mold 203 and the lower mold 202 are in the mold closing state, if the piston rod of the third driving cylinder 2045 is excessively extended, the second rocker arm 2042 will abut against the limiting protrusion 8, thereby preventing the second rocker arm 2042 from rotating on the pressing arm 2043 at too large an angle, resulting in mold closing failure, which is beneficial to improving operation stability.

[0037] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
