Description

Technical Field

[0001] The invention relates to an injection molding demoulding mechanism. Background Art

[0002] Plastic molds are tools used in the plastics processing industry to match plastic molding machines and give plastic products complete configurations and precise dimensions. Due to the wide variety of plastics and processing methods, and the varying complexity of the structures of plastic molding machines and plastic products, there are also many types and structures of plastic molds.

[0003] In actual injection molding production, the structural characteristics of the product necessitate the installation of multiple sets of internal sliders in both the front and rear molds. Furthermore, during the mold opening process, the opening sequence of each mold surface must be controlled to ensure that the front and rear mold sliders operate in the set sequence for smooth product demolding. This necessitates designing different slider demolding angles and a sequential mold opening sequence within the mold structure. To address this, an injection molding demolding mechanism was developed. Summary of the Invention

[0017] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0018] The technical solution specifically implemented in the present invention is: like Figures 1 to 7 As shown, an injection molding demoulding mechanism includes a front mold, a rear mold, a first sequence mold opening assembly 1, a second sequence mold opening assembly 2, multiple groups of front mold inner slider assemblies and multiple groups of rear mold inner slider assemblies; The first sequential mold opening assembly 1 and the second sequential mold opening assembly 2 are arranged between the front mold and the rear mold; The front mold includes an A plate 3 and a B plate 4, and the back mold includes a C plate 5 and a D plate 6. A cavity for molding the product 100 is formed between the B plate 4 and the C plate 5. The plurality of groups of front mold inner slider assemblies are arranged in the front mold, and each group of the front mold inner slider assemblies includes a front mold inner slider 7 and a front mold inner slider shovel base 8, the front mold inner slider shovel base 7 is arranged on the A plate 3, the front mold inner slider 8 is arranged on the B plate, and the front mold inner slider 7 is connected to the front mold inner slider shovel base 8; The multiple groups of rear mold slider assemblies are arranged in the rear mold, and each group of the rear mold slider assemblies includes a rear mold slider 9 and a rear mold slider shovel base 10. The rear mold slider shovel base 10 is arranged on the D plate 6, and the rear mold slider 9 is arranged on the C plate 5, and the rear mold slider 9 is connected to the rear mold slider shovel base 10.

[0019] Furthermore, the front mold inner slider assembly also includes a front mold slider bead 11, and the front mold slider bead 11 is arranged between the front mold inner slider 7 and the front mold inner slider shovel base 8.

[0020] Furthermore, the rear mold slider assembly also includes a rear mold slider bead 12, and the rear mold slider bead 12 is arranged between the rear mold slider 9 and the rear mold slider shovel base 10.

[0021] Furthermore, the rear mold further includes an ejector plate 13 and an ejector pin 14 , one end of the ejector pin 14 is connected to the ejector plate 13 , and the other end of the ejector pin 14 extends into the mold cavity.

[0022] The working method of an injection molding demoulding mechanism of the present invention comprises the following steps: Step 1: The mold is closed, the distance between the A plate 3 and the B plate 4 is 0, the distance between the B plate 4 and the C plate 5 is 0, and the distance between the C plate 5 and the D plate 6 is 0, and the product 100 is injection molded in the cavity; Step 2: The mold is opened for the first time. Under the action of the first-order mold opening assembly 1 and the second-order mold opening assembly 2, the A plate 3 and the B plate 4 are opened first, and the front mold inner slider 7 is driven to move by the front mold inner slider shovel base 8 provided on the A plate 3, so that the distance between the A plate 3 and the B plate 4 increases from 0 to X1, thereby making the front mold inner slider 7 escape from the undercut; then the C plate 5 and the D plate 6 are opened, and the rear mold inner slider shovel base 10 provided on the D plate 6 drives the rear mold inner slider 9 to move, so that the distance between the C plate 5 and the D plate 6 increases from 0 to X2, thereby making the rear mold inner slider 9 escape from the undercut, and at this time the distance between the B plate 4 and the C plate 5 does not change to 0; Step 3: The mold is opened for the second time. The first-order mold opening component 1 and the second-order mold opening component 2 remove the restriction on the C plate 5. First, the B plate 4 and the C plate 5 are opened, so that the distance between the B plate 4 and the C plate 5 increases from 0 to X3. At this time, the mold is fully opened. Finally, the ejector plate 13 drives the ejector 14 to move, and the product 100 is ejected from the cavity.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
