[0006] Furthermore, a through hole is opened on the upper surface of the upper mold frame corresponding to the position of the ejector, and the through hole is connected to the groove. The lower end of the ejector is expanded outward in a trumpet shape to form a conical head, and one end of the through hole located in the groove is expanded outward to form a trumpet-shaped inclined annular surface that fits the lower end of the ejector. When the upper mold frame descends to the extreme position, the conical head is embedded in the through hole.

[0007] Furthermore, it also includes a controller, which is communicatively connected with the driving mechanism to control the driving mechanism to move downward or drive the lower mold frame downward.

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 3 As shown, the utility model provides a mold opening synchronous ejection mold frame, including a base 10, an ejector 20, a lower mold frame 30, an upper mold frame 40, an ejector pin 21, and a driving mechanism 50; a guide column 11 is arranged between the base 10 and the ejector 20, the ejector 20 is located above the base 10 and at the top of the guide column 11, the base 10 is located at the bottom of the guide column 11, and an injection molding opening is opened on the base 10; the lower mold frame 30 is arranged on the upper surface of the base 10; the upper mold frame 40 is sleeved on the guide column 11, and can be lifted and slid along the guide column 11, The side facing the base 10 is concave to form a groove 41, and when the upper mold frame 40 descends to the extreme position, the lower mold frame 30 and the groove 41 are sealed to form a cavity 411, and the injection opening is connected with the cavity 411; the ejector pin 21 is arranged on the lower surface of the top seat 20 and extends vertically downward, the upper mold frame 40 is sleeved on the ejector pin 21, and slides up and down along the ejector pin 21. When the upper mold frame 40 descends to the extreme position, the bottom of the ejector pin 21 is flush with the bottom of the groove 41; the driving mechanism 50 is connected and drives the upper mold frame 40 to rise or descend to the extreme position.

[0021] The upper mold frame 40 of the utility model moves upward, so that the sealed cavity 411 is opened, thereby opening the mold. When the upper mold frame 40 moves upward, the ejector pin 21 pushes the injection molding mold, so that the mold moves downward relative to the upper mold frame 40, so that the mold is separated from the upper film frame. Therefore, the utility model can eject the material while opening the mold, which simplifies the demoulding process, saves time, reduces production costs, and has a relatively simple overall structure.

[0022] Furthermore, a through hole 42 is provided on the upper surface of the upper mold frame 40 at a position corresponding to the ejector pin 21, and the through hole 42 is connected to the groove 41. The lower end of the ejector pin 21 is expanded outward in a trumpet shape to form a conical head 211, and one end of the through hole 42 located in the groove 41 is expanded outward to form a trumpet-shaped inclined annular surface that fits the lower end of the ejector pin 21. When the upper mold frame 40 is lowered to the limit position, the conical head 211 is embedded in the through hole 42. Specifically, the conical head 211 can increase the contact area between the ejector pin 21 and the mold, increase the force-bearing area of ​​the mold, so as to facilitate the separation of the mold and the upper mold frame 40, and also prevent the local pressure of the mold from being too large, resulting in mold rupture. Specifically, when the upper mold frame 40 is lowered to the limit position, the conical head 211 is embedded in the inclined annular surface in the through hole 42 to position the upper mold frame 40, so that the upper mold frame 40 cannot continue to move downward. Specifically, the number of ejector pins 21 is not limited here and can be set according to actual conditions.

[0023] Furthermore, a controller (not shown in the figure) is included, and the controller is in communication connection with the driving mechanism 50 to control the driving mechanism 50 to drive the lower mold frame 30 downward or upward;

[0024] Specifically, a stop block 22 is provided on the lower surface of the top seat 20, and a first sensor (not shown in the figure) is provided on the stop block 22. The first sensor is communicatively connected to the controller, and the driving mechanism 50 drives the upper mold frame 40 to rise, so that the first sensor is triggered when the upper surface of the upper mold frame 40 abuts against the stop block 22. The first sensor controls the driving mechanism 50 to stop through the controller. Specifically, the first sensor can be, for example, a pressure sensor, which can transmit a sensor signal to the controller after detecting the pressure given by the upper mold, so as to control the upper mold frame 40 to stop rising through the driving mechanism 50. The first sensor can also be other sensors that can be triggered when the upper mold frame 40 abuts against the stop block 22, and transmit a signal to the controller to control the driving mechanism 50 to stop rising, which is not limited here; specifically, the driving mechanism 50 is, for example, a cylinder, a linear motor, etc. that can drive the upper mold frame 40 to rise and fall, and is fixed on the top seat 20, which is not limited here.

[0025] Furthermore, a matching structure 12 is provided on the base 10, and a locking structure 43 is also provided on the upper mold frame 40. The locking structure 43 is used to lock with the matching structure 12 when the lower mold frame 30 descends to the extreme position, so as to lock the upper mold frame 40 and the base 10 together.

[0026] Specifically, the locking structure 43 includes an arm 431, which is vertically arranged, with its upper end fixed on the side wall of the upper mold frame 40, and its lower end extending vertically downward to the base 10. The arm 431 rises or falls synchronously with the upper mold frame 40, and a spring pin 432 is arranged at its lower end; the matching structure 12 is a socket 121 on the base 10 located on the descending path of the lower end of the arm 431, and the spring pin 432 is aligned with the socket 121 when descending with the arm 431, and is inserted into the socket 121 to lock the upper mold frame 40 and the base 10 together. Specifically, the upper mold frame 40 and the base 10 are unlocked by manually pulling the spring pin 432; specifically, the locking structure 43 and the matching structure The structure 12 may also be other structures that can lock the base 10 and the upper mold frame 40 together by cooperation, which is not limited here; it can be understood that the lower end of the support arm 431 extends vertically downward to the base 10, and the spring pin 432 is arranged at the lower end of the support arm 431, so that the spring pin 432 is in a compressed state, even when the upper mold frame 40 rises to the position of the stop block 22, the lower end of the support arm 431 is still located at the base 10, and the spring pin 432 is still in a compressed state, that is, the spring pin 432 rises and falls on the side wall of the base 10 in a compressed state, and aligns with the socket 121 when descending and stretches to be inserted into the socket 121, so the spring pin 431 will only stretch when it is aligned with the socket 121;

[0027] Specifically, a second sensor (not shown in the figure) is provided at the socket 121, and the second sensor is communicatively connected with the controller. The second sensor is used to be triggered when the spring pin 432 is inserted into or out of the socket 121, so as to control the driving mechanism 50 to stop driving the upper mold frame 40 to descend, or to control the driving mechanism 50 to drive the upper mold frame 40 to lift upward. Specifically, when the spring pin 432 is inserted into the socket 121, the second sensor controls the driving mechanism 50 to stop, and when the spring pin 432 is out of the socket 121, the second sensor controls the driving mechanism 50 to rise, and drives the upper mold frame 40 to rise. Specifically, when the spring pin 432 is inserted into the socket 121, the second sensor controls the driving mechanism 50 to rise, and drives the upper mold frame 40 to rise. When 432 is inserted into the socket 121, pressure is applied to the second sensor, and the second sensor is triggered to transmit a signal to the controller, and the controller controls the driving mechanism 50 to stop. When the spring pin 432 is pulled out, the pressure applied to the second sensor by the spring pin 432 disappears, and the second sensor is triggered to transmit a signal to the controller, and the controller controls the driving mechanism 50 to move upward, thereby driving the upper mold frame 40 to move upward. The second sensor can be, for example, a pressure sensor, or other sensors that are triggered to transmit signals to the controller and control the driving mechanism 50 when the spring pin 432 is inserted into and out of the socket 121, and are not limited here.

[0028] Furthermore, when the upper mold frame 40 descends to the limit position, the lower mold frame 30 is embedded in the groove 41 to form the cavity 411 and maintain the sealing of the cavity 411 .
