DETAILED DESCRIPTION

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] One of the preferred embodiments of the present application is as follows: Figures 1 to 5 As shown, a heat shield mold frame includes a mold frame body 1, a driving device 2, an upper mold 3, a lower mold 4 and an ejection mechanism 7, the driving device 2 is installed at the top of the mold frame body 1, the upper mold 3 is installed at the output end of the driving device 2, the lower mold 4 is installed at the lower end of the mold frame body 1, the ejection mechanism 7 is installed at the lower end of the mold frame body 1 and cooperates with the lower mold 4, and the ejection mechanism 7 is connected to the output end of the driving device 2.

[0025] It is understandable that when the mold is opened, the drive device 2 can drive the upper mold 3 to move upward and away from the lower mold 4. Of course, the drive device 2 can also drive the ejection mechanism 7 to operate, so that the ejection mechanism 7 can eject the product A in the lower mold 4 from the mold.

[0026] In layman's terms, the ejection mechanism 7 and the upper mold 3 share a driving device 2, which can save resources and reduce costs, and can also reduce the complexity of the control system, thereby achieving stable operation between the two and improving production efficiency and accuracy.

[0027] It should be noted that the specific structure and working principle of the driving device 2 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here; common driving devices 2 include hydraulic cylinders, pneumatic cylinders, and linear motors, etc., and those skilled in the art can choose according to actual needs.

[0028] One of the embodiments of the present application is as follows: Figure 4 As shown, the ejection mechanism 7 includes a plurality of ejector columns 701, a mounting plate 702 and a moving block 703. The ejector column 701 is vertically slidably installed in the lower mold 4 and the bottom end is connected to the mounting plate 702. The moving block 703 is elastically slidably installed at the lower end of the mold frame body 1 through a spring and is connected to the output end of the driving device 2 through a rope 6.

[0029] It is understandable that when the mold is opened, the upper mold 3 moves upward, and then the moving block 703 is pulled by the rope 6 to move, and the moving block 703 and the mounting plate 702 are wedge-shaped pressed together, so that the mounting plate 702 moves vertically upward, so that the ejector 701 extends out of the lower mold 4 to eject the product A. When the mold is closed, the same is true. At this time, the lower mold 4 moves downward, and the moving block 703 moves and resets under the elastic force of the spring, and the mounting plate 702 moves downward and resets to the initial state under the action of gravity. It should be known that the ejector 701 is flush with the inner bottom of the lower mold 4 in the initial state, that is, it does not affect the molding and injection molding of the mold.

[0030] Further, such as Figure 3 As shown, in order to facilitate the guidance of the rope 6, a guide wheel 9 can be installed at the lower end of the mold frame body 1, and the rope 6 passes through the guide wheel 9 so that the rope 6 moves smoothly along the set path. The guide wheel 9 can effectively reduce the friction resistance of the rope 6 and ensure the smoothness of the movement.

[0031] As we all know, after the molding of product A, since the ejector pin 701 also participates in the molding process in the lower mold 4, the ejector pin 701 will also be bonded to product A. If the diameter of the ejector pin 701 is too small, its own strength is low, and when ejecting product A, since the contact area with product A is too small, although it is easy to separate from product A, it is easy to cause product A to be damaged by local pressure. Moreover, using many groups of ejector pins 701 will make the structure complicated. If the diameter of the ejector pin 701 is too large, it will be difficult to separate product A from the ejector pin 701.

[0032] In order to solve the above problem, one of the embodiments of the present application is aimed at the case where the diameter of the top column 701 is large, such as Figure 4 and Figure 5 As shown, the top column 701 is rotatably mounted on the mounting plate 702 , and the top column 701 and the lower mold 4 are matched through the guide structure 12 .

[0033] It is understandable that, when the mold is opened, the top column 701 can be driven by the guide structure 12 to move vertically upward and rotate axially at the same time, so that the top column 701 is separated from the product A. In layman's terms, the top column 701 can rotate while lifting the product A upward, and the top of the top column 701 is separated from the product A through rotation, thereby facilitating the subsequent removal work.

[0034] As a further description of the above technical solution: Figure 5 As shown, the guide structure 12 includes a guide block 1201 and a guide groove 1202. The guide block 1201 is installed on the lower mold 4. The guide groove 1202 is arranged on the outside of the top column 701. The guide groove 1202 includes a vertical section and a spiral section that are connected.

[0035] It is understandable that when the top column 701 moves upward or downward, if the guide block 1201 cooperates with the spiral section, the top column 701 rotates and moves axially. When the guide block 1201 cooperates with the vertical section, the top column 701 moves axially.

[0036] It should be known that when the ejector pin 701 is in the initial state in the lower mold 4, the guide block 1201 is located in the spiral section. Therefore, when the ejector pin 701 is initially moved upward, the ejector pin 701 will rotate and disengage from the product A, while the product A is still located in the lower mold 4. When the guide block 1201 and the vertical section cooperate, the ejector pin 701 will eject the product A out of the concave mold of the lower mold 4 or remain in the concave mold, and will not rotate to affect the ejection stability of the product A.

[0037] Based on the above embodiments, another embodiment of the present application is that the heat shield mold frame also includes an ejector assembly 8, which is installed on the mounting plate 702 and cooperates with the moving block 703; when opening the mold, the ejector column 701 will first lift the product A upward and position it above the concave mold of the lower mold 4, and then the ejector assembly 8 can lift and tilt one end of the product A upward under the drive of the moving block 703, so that the product A is moved out of the lower mold 4 under the action of gravity, thereby realizing the process of demolding and taking the material, that is, there is no need for manual material taking, which greatly improves the convenience.

[0038] As a further description of the above technical solution: Figure 4 As shown, the ejector column 701 is arranged on the front and rear sides of the lower mold 4, and the ejector assembly 8 includes a plurality of ejector pins 801. The ejector pins 801 are vertically slidably installed on the mounting plate 702 and are connected and cooperated with the ejector column 701 on one side (the front side or the rear side), and a mounting block 802 is arranged at the bottom end of the ejector pin 801.

[0039] It is understandable that when the mold is opened, the ejector pin 801 is vertically moved upward and extended out from the ejector column 701 under the wedge-shaped extrusion cooperation of the moving block 703 and the mounting block 802, and at this time, the ejector column 701 remains stationary.

[0040] In order to facilitate a clearer understanding of the ejection mechanism 7 and the ejection assembly 8, the working principles thereof are described below:

[0041] like Figure 4 As shown, first, two wedge blocks 10 arranged front and back are installed on the moving block 703, and wedge blocks 10 are also installed at the bottom ends of the mounting plate 702 and the mounting block 802, and the wedge blocks 10 are of a right-angled trapezoidal structure, and the two wedge blocks 10 on the moving block 703 are arranged front and back and correspond to the wedge blocks 10 on the mounting plate 702 and the mounting block 802 respectively.

[0042] When the mold is opened, the moving block 703 will move under the pull of the rope 6. When moving, the wedge block 10 located on the front side of the moving block 703 will first cooperate with the wedge block 10 on the mounting plate 702. The inclined surfaces of the two are squeezed and matched to make the ejector column 701 move upward (of course, the ejector pin 801 and the mounting block 802 will also move upward synchronously). While moving upward, the ejector column 701 is rotated through the guide structure 12. When the ejector column 701 moves to the extreme position (product A will be ejected out of the groove of the lower mold 4), the horizontal surfaces of the two wedge blocks 10 will cooperate.

[0043] Then the moving block 703 continues to move, and the wedge block 10 on the rear side of the moving block 703 cooperates with the wedge block 10 on the mounting block 802. The inclined surfaces of the two are squeezed and matched to make the ejector pin 801 in the rear (or front) ejector column 701 move upward to lift the product A and make it tilted, as shown in FIG. Figure 1 and Figure 2 As shown, the product A slides down under the action of gravity. Of course, the wedge block 10 on the front side and the wedge block 10 on the mounting plate 702 are always matched in a horizontal plane, so that the top column 701 remains stationary.

[0044] It should be noted that, although ejector pin 801 and product A are in a bonded state at this time, due to the small diameter of ejector pin 801, that is, the bonding force is also small, and product A is in an inclined state, the ejector pin 801 and product A will be forcibly separated under the action of gravity.

[0045] In a preferred embodiment, Figure 4 As shown, after the moving block 703 moves and resets, that is, the mounting plate 702 and the mounting block 802 lose the wedge-shaped extrusion fit, they will move down and reset under the action of gravity, but there may be a stuck phenomenon, so the mounting plate 702 and the bottom end of the lower mold 4 are connected by an elastic member 11, and the mounting block 802 and the bottom end of the mounting plate 702 are also connected by an elastic member 11, so that the mounting plate 702 and the mounting block 802 can be smoothly and stably moved down and reset under the action of elastic force, and the elastic member 11 here is preferably a spring. It should be noted that the force of the elastic member 11 will not be very large, that is, it will not interfere with the movement and reset of the moving block 703.

[0046] In one of the embodiments of the present application, Figure 1 As shown, the mold frame body 1 is also equipped with an inclined material guide plate 5, and a collection frame or a belt conveyor can be placed at the lower end of the material guide plate 5 to facilitate material collection of the product A removed from the lower mold 4.

[0047] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
