DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figures 1-5 The device for demoulding a product of an injection molding machine shown in the figure comprises a device support 100, a static mold seat 101 fixed to the inner side wall of the device support 100, and a movable mold seat 102 which can translate inside the device support 100. A translatory seat 200 which can translate is provided inside the device support 100. The translatory seat 200 is used to drive the horizontal lateral movement of the movable mold seat 102. A connecting slide 204 is fixedly connected to the corner of the translatory seat 200 which is away from the movable mold seat 102. One end of the connecting slide 204 passes through the side wall of the device support 100 and is fixedly connected to a connecting plate 2 03. A telescopic cylinder 205 is fixedly connected to one side of the device bracket 100 away from the static mold base 101. The telescopic cylinder 205 is used to drive the connecting plate 203 to move horizontally. The extension or retraction of the telescopic cylinder 205 is controlled by an external switch, so that the translation seat 200 is driven to move through the connecting plate 203 and the connecting slide rod 204. Since the translation seat 200 and the movable mold base 102 are relatively fixedly arranged, the movable mold base 102 can be driven to move horizontally, thereby achieving the purpose of tightly fitting or separating the movable mold base 102 and the static mold base 101.

[0023] Furthermore, a sliding seat 208 is movably provided between the translation seat 200 and the movable mold seat 102, and fixed rods are fixedly connected to the two side positions between the movable mold seat 102 and the translation seat 200, and the outer wall of the fixed rod is movably plugged into the side of the sliding seat 208. The fixed rod keeps the movable mold seat 102 and the translation seat 200 in a fixed position, and at the same time supports and guides the sliding seat 208, so that the sliding seat 208 can stably move laterally between the movable mold seat 102 and the translation seat 200. A ejector pin 201 is fixedly provided on the side of the sliding seat 208 facing the movable mold seat 102, and the outer wall of the ejector pin 201 can penetrate the side wall of the movable mold seat 102. The outer wall of the ejector pin 201 is sleeved with an elastic compression spring 202 fixedly connected to the sliding seat 208 and the movable mold seat 102 respectively, and a top extension block 207 is fixedly connected to the side of the sliding seat 208 away from the movable mold seat 102, and one end of the top extension block 207 penetrates the side wall of the translation seat 200 and extends To the outside, a convex seat 206 is fixedly connected to one side of the inner side of the device bracket 100 facing the ejection block 207. When the translation seat 200 moves in the direction of the convex seat 206 to drive the movable mold seat 102 to separate from the static mold seat 101, as the translation seat 200 continues to move, the ejection block 207 contacts and squeezes the convex seat 206, so that the convex seat 206 is used to push the ejection block 207 to move, driving the ejector pin 201 to extend from the side of the movable mold seat 102 facing the static mold seat 101, thereby ejecting the injection molded product attached to the movable mold seat 102 to achieve the demoulding effect. In this way, the movable mold seat 102 can achieve the purpose of automatic demoulding during the separation process from the static mold seat 101, the process is simple and the efficiency is high. The setting of the elastic compression spring 202 can enable the movable mold seat 102 to move back and reset, drive the sliding seat 208 to reset, and automatically retract the ejector pin 201 into the movable mold seat 102 for reset, so as to facilitate subsequent continued use.

[0024] In a preferred embodiment, the extension block 207 includes an internally threaded tube body 271 fixedly connected to the side wall of the sliding seat 208, a baffle 272 is provided on the side of the internally threaded tube body 271 facing away from the translation seat 200, a threaded rod 273 is fixedly connected to the side of the baffle 272 facing the internally threaded tube body 271, and the outer wall of the threaded rod 273 is connected to the inner thread of the internally threaded tube body 271. By manually rotating the baffle 272 clockwise or counterclockwise, the threaded rod 273 is driven to rotate and extend into or out of the internally threaded tube body 271, so that the length of the extension block 207 can be adjusted to meet the control of the demolding position of the injection molded product, which helps to improve the adaptability of use and the quality of work.

[0025] Immediately above the stationary mold base 101, there is an air injection pipe 300 fixed to the device bracket 100. A plurality of air nozzles 301 are fixedly inserted into the side wall of the air injection pipe 300. The plurality of air nozzles 301 are arranged obliquely downward and communicate with the inside of the air injection pipe 300. A gas supply mechanism is provided between the moving mold base 200 and the device bracket 100. The gas supply mechanism is used to transport gas into the air injection pipe 300. When the moving mold base 102 moves, it drives the gas supply mechanism to act, so that the gas supply mechanism sends gas into the air injection pipe 300 and sprays it out from the air nozzles 301. In this way, the injection-molded product on it can be cooled during the movement of the moving mold base 102, reducing the adhesion between the injection-molded product and the moving mold base 102 and improving the convenience of subsequent demolding. Preferably, the gas supply mechanism includes an air cylinder 302 fixed to the inner side of the device bracket 100. A piston rod 303 is movably inserted into one end of the air cylinder 302. A connecting seat 304 is fixedly connected between one end of the piston rod 303 and the moving seat 200. A connecting hose 306 is provided between the air cylinder 302 and the air injection pipe 300. The connecting hose 306 is used to connect the air outlet of the air cylinder 302 and the air inlet of the air injection pipe 300. A one-way intake pipe 305 is provided at the end of the air cylinder 302. The one-way intake pipe 305 is used for the transmission of external gas into the inside of the air cylinder 302. During the process of the moving mold base 102 moving horizontally and separating from the stationary mold base 101, it drives the piston rod 303 to press into the air cylinder 302, pressing the gas in the air cylinder 302 out through the connecting hose 306, into the air injection pipe 300, and then spraying it out from the air nozzles 301. Since the air nozzles 301 are arranged obliquely downward, with the horizontal movement of the moving mold base 102, jet cooling of the surface of the injection-molded product is achieved. The one-way intake pipe 305 is provided with a one-way valve, which can allow external gas to enter the air cylinder 302 during the process of the piston rod 303 being withdrawn from the air cylinder 302 to achieve the purpose of air replenishment.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
