A sole production mold

Abstract

The present invention discloses a sole production mold, which includes a lower mold and a mounting seat. The lower mold is composed of two side molds and an intermediate mold. In this device, the lower mold is divided into an intermediate mold and two side molds hinged on both sides thereof. In the demolding process, when two first U-shaped handles are used to press down the two side molds simultaneously, the side molds are separated from the intermediate mold, and both sides of the sole and both sides of the bottom of the sole will be exposed on both sides of the intermediate mold, facilitating the worker to drag the sole from both sides to demold it. Moreover, as the side mold is pressed down, the semi-circular guard plate fixed at the side end of the side mold rotates together. At this time, the bottom end of the semi-circular guard plate no longer abuts against the cross plate, and the arc-shaped ejector rod at the bottom of the side mold pushes up the cross plate through the ball at its end. In this way, the cross plate drives the ejector plate to move upward, and then the sole in the sole forming groove of the intermediate mold can be effectively ejected, so that the sole can be easily demolded from the sole forming groove of the intermediate mold without the need for the worker to drag it.

Description

Technical Field

[0001] The present invention relates to the technical field of sole molds, and particularly relates to a sole production mold. Background Art

[0002] In the production process of soles, the mold is an indispensable key device. When traditional sole molds are demolded, it is usually necessary for workers to operate with the help of tools, or rely on the structural design of the mold itself to achieve demolding. However, there are some problems with the existing sole molds during demolding. For example, manual demolding is difficult and requires contact with tools such as pliers and screwdrivers to achieve demolding. When demolding by mechanical ejection, it is easy to cause damage to the sole and also easy for the raw material to flow out from the gaps of the ejection mechanism, affecting product quality and production efficiency. Especially for some soles with complex shapes, the demolding difficulty is greater and more time and effort are required. Therefore, how to design a sole mold that is convenient for demolding has become an urgent problem for those skilled in the art.

[0003] To solve the above problems, the present invention proposes a sole production mold. Summary of the Invention

[0004] To solve the above existing problems, the present invention provides a sole production mold.

[0005] The present invention is realized through the following technical solutions:

[0006] A sole production mold includes a lower mold and a mounting seat. The lower mold is composed of two side molds and an intermediate mold. The two side molds are respectively symmetrically attached to both sides of the intermediate mold, and the bottom surface of the side mold is hinged to one side of the bottom surface of the intermediate mold through a hinge structure. A sole forming groove is commonly opened in the middle area of the top surface of the intermediate mold and in the areas of the top surfaces of the two side molds close to the intermediate mold. A plurality of semi-circular guard plates are evenly fixed on the side of the side mold close to the intermediate mold. The axis line of the hinge between the side mold and the intermediate mold is the same as the axis line of the semi-circular guard plate. The top end of the semi-circular guard plate is aligned with the bottom surface of the sole forming groove. The semi-circular guard plate penetrates through the intermediate mold and is slidably connected to the contact part therewith. An arc-shaped groove for the semi-circular guard plate to pass through is opened on the side of the intermediate mold close to the side mold. A limiting block is fixed at the bottom end of the inner arc surface of the semi-circular guard plate.

[0007] Preferably, a connecting plate is fixed at one end of the intermediate mold, and positioning bolts are respectively screwed at both ends of the connecting plate. The end of the positioning bolt is inserted into the side wall of the side mold, and a positioning hole for the end of the positioning bolt to be inserted is opened on the side wall of the side mold.

[0008] Preferably, an upper mold is hinged to the other end of the intermediate mold through a hinge structure, and a second U-shaped handle is fixed on the upper mold.

[0009] Preferably, a plurality of reserved grooves are evenly formed in the bottom surface of the sole forming groove of the middle mold. A ejector plate matching the volume thereof is arranged in each reserved groove. The top surface of the ejector plate is aligned with the bottom surface of the sole forming groove of the middle mold. A sliding plate is fixed to the bottom surface of the ejector plate. The bottom end of the sliding plate vertically penetrates through the middle mold and is slidably connected to the contact portion thereof. A cross plate is arranged at the lower end of the middle mold. The bottom end of each sliding plate is fixedly connected to the top surface of the cross plate. Guide rods are vertically penetrated through the four corners of the cross plate respectively. The guide rods are slidably connected to the cross plate. The top end of the guide rod is fixedly connected to the bottom surface of the middle mold. A T-shaped slider is fixed to the bottom end of the guide rod. The bottom end of the semi-circular guard plate is attached to the top surface of the cross plate. A plurality of arc-shaped ejector rods are evenly fixed to the bottom surface of the side mold. The axis line of the hinge between the side mold and the middle mold is consistent with the axis line of the arc-shaped ejector rod. A ball is fixedly arranged at the end of the arc-shaped ejector rod.

[0010] Preferably, the mounting seat includes a base. Support plates are respectively fixed at both ends of the top surface of the base. Two guide plates are symmetrically fixed between the two support plates. T-shaped chutes are formed in the top surfaces of the two guide plates. The T-shaped slider is slidably arranged in the T-shaped chute.

[0011] Preferably, two trapezoidal support plates are symmetrically fixed on the top surface of the base.

[0012] Preferably, a first U-shaped handle is fixed on the side wall of the side mold.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The device divides the lower mold into a middle mold and two side molds hinged on both sides thereof. In the demolding process, when the two first U-shaped handles are used to simultaneously press down the two side molds, the side molds are separated from the middle mold. At this time, the sole forming groove on the side mold is separated from the sole forming groove of the middle mold. The formed sole remains in the sole forming groove of the middle mold. Both sides of the sole and both sides of the bottom of the sole will be exposed on both sides of the middle mold, which is convenient for workers to drag it from both sides of the sole to demold it. Moreover, as the side mold is pressed down, the semi-circular guard plate fixed to the side end of the side mold rotates together. At this time, the bottom end of the semi-circular guard plate no longer abuts against the cross plate. The arc-shaped ejector rod at the bottom of the side mold pushes up the cross plate through the ball at its end. In this way, the cross plate drives the ejector plate to move upward, and then the sole in the sole forming groove of the middle mold can be effectively ejected, and the sole can be easily demolded from the sole forming groove of the middle mold without the need for workers to drag it.

[0015] 2. Through the provision of the trapezoidal support plate, during the hot pressing process, the top surface of the trapezoidal support plate abuts against the side mold, preventing the side mold from rotating around the hinge of the hinge joint with the middle mold when the hot press squeezes the mold. Furthermore, it ensures that the side mold and the middle mold are also tightly fitted during the hot pressing process, effectively preventing the raw material from flowing out through the gap between the side mold and the middle mold.

[0016] 3. Through the provision of the semi-circular guard plate, during the hot pressing process, the bottom end of the semi-circular guard plate abuts against the cross plate, preventing the ejector plate from detaching from the reserved groove in the sole forming groove of the middle mold during the hot pressing process, ensuring that the ejector plate is tightly buckled in the reserved groove, effectively preventing the raw material from flowing out through the reserved groove. Moreover, during the demolding process, through the provision of the semi-circular guard plate, when the sole forming groove on the side mold separates from the sole forming groove of the middle mold, it can not only play a role in guiding and stabilizing, but also the outer arc surface of the semi-circular guard plate can effectively protect the sole, preventing the sole from directly contacting and bumping against the edges and corners on the side mold and the middle mold during the separation process, thereby effectively avoiding damage to the sole.

[0023] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0024] Such as Figure 1 , Figure 2 , Figure 3 ,Figure 4 , Figure 5 As shown in Figure 5 , a sole production mold includes a lower mold 2 and a mounting seat 23. The lower mold 2 is composed of two side molds 4 and an intermediate mold 3. The two side molds 4 are symmetrically attached to both sides of the intermediate mold 3 respectively, and the bottom surface of the side mold 4 is hinged to one side of the bottom surface of the intermediate mold 3 through a hinge structure. A sole forming groove is commonly opened in the middle area of the top surface of the intermediate mold 3 and the areas of the top surfaces of the two side molds 4 close to the intermediate mold 3. A plurality of semi-circular guard plates 14 are uniformly fixed on one side of the side mold 4 close to the intermediate mold 3. The axis line of the hinge between the side mold 4 and the intermediate mold 3 is consistent with the axis line of the semi-circular guard plate 14. The top end of the semi-circular guard plate 14 is aligned with the inner bottom surface of the sole forming groove. The semi-circular guard plate 14 penetrates through the intermediate mold 3 and is slidably connected to the contact part therewith. An arc-shaped groove 22 for the semi-circular guard plate 14 to pass through is opened on one side of the intermediate mold 3 close to the side mold 4. A limiting block 21 is fixed at the bottom end of the inner arc surface of the semi-circular guard plate 14.

[0025] Preferably, a connecting plate 6 is fixed at one end of the intermediate mold 3. Positioning bolts 7 are respectively screwed at both ends of the connecting plate 6. The end parts of the positioning bolts 7 are inserted into the side wall of the side mold 4. Positioning holes for the end parts of the positioning bolts 7 to be inserted are opened on the side wall of the side mold 4.

[0026] Preferably, an upper mold 1 is hinged to the other end of the intermediate mold 3 through a hinge structure. A second U-shaped handle 24 is fixed on the upper mold 1.

[0027] Preferably, a plurality of reserved grooves are uniformly opened on the inner bottom surface of the sole forming groove of the intermediate mold 3. A ejector plate 8 with a volume matching that of each reserved groove is arranged in each reserved groove. The top surface of the ejector plate 8 is aligned with the inner bottom surface of the sole forming groove of the intermediate mold 3. A sliding plate 15 is fixed at the bottom surface of the ejector plate 8. The bottom end of the sliding plate 15 vertically penetrates through the intermediate mold 3 and is slidably connected to the contact part therewith. A cross plate 20 is arranged at the lower end of the intermediate mold 3. The bottom end of each sliding plate 15 is fixedly connected to the top surface of the cross plate 20. Guide rods 16 are vertically penetrated through the four corners of the cross plate 20 respectively. The guide rods 16 are slidably connected to the cross plate 20. The top end of the guide rod 16 is fixedly connected to the bottom surface of the intermediate mold 3. A T-shaped slider 17 is fixed at the bottom end of the guide rod 16. The bottom end of the semi-circular guard plate 14 is attached to the top surface of the cross plate 20. A plurality of arc-shaped ejector rods 18 are uniformly fixed on the bottom surface of the side mold 4. The axis line of the hinge between the side mold 4 and the intermediate mold 3 is consistent with the axis line of the arc-shaped ejector rod 18. A ball 19 is fixed at the end part of the arc-shaped ejector rod 18.

[0028] Preferably, the mounting base 23 includes a base 9. At both ends of the top surface of the base 9, support plates 10 are respectively fixed. Between the two support plates 10, two guide plates 11 are symmetrically fixed left and right. T-shaped chutes 12 are formed on the top surfaces of the two guide plates 11, and the T-shaped sliders 17 are slidably disposed in the T-shaped chutes 12.

[0029] Preferably, two trapezoidal support plates 13 are symmetrically fixed left and right on the top surface of the base 9.

[0030] Preferably, a first U-shaped handle 5 is fixed on the side wall of the side mold 4.

[0031] Working principle: When the present invention is in use, the part of the trapezoidal support plate 13 provided on the base 9 is installed in the hot press. An appropriate amount of raw materials for making shoe soles is placed in the shoe sole forming groove of the upper mold 1, and then the upper mold 1 is closed through the second U-shaped handle 24. Then, the lower mold 2 is pushed, so that the lower mold 2 slides into the hot press along the guide plate 11. At this time, the bottom surfaces of the two side molds 4 of the lower mold 2 are attached to the top surface of the trapezoidal support plate 13, preventing the side molds 4 from rotating around the hinge at the hinge joint with the middle mold 3 when the hot press squeezes the molds, thereby ensuring that the side molds 4 and the middle mold 3 are also closely attached during the hot pressing process, effectively preventing the raw materials from flowing out through the gap between the side mold 4 and the middle mold 3. When the hot pressing work is completed, the upper mold 1 and the lower mold 2 are pulled out of the hot press through the second U-shaped handle 24. At this time, the bottom surfaces of the two side molds 4 of the lower mold 2 are separated from the trapezoidal support plate 13. Then, the upper mold 1 is opened from the lower mold 2 through the second U-shaped handle 24. Subsequently, the positioning bolt 7 is loosened, so that the end of the positioning bolt 7 is disengaged from the positioning hole on the side mold 4. Then, the two side molds 4 are simultaneously pressed down through the two first U-shaped handles 5. In this way, the side molds 4 rotate around the hinge at the hinge joint with the middle mold 3, and the side molds 4 and the middle mold 3 are separated. At this time, the shoe sole forming groove on the side mold 4 is separated from the shoe sole forming groove of the middle mold 3, and the formed shoe sole remains in the shoe sole forming groove of the middle mold 3. Both sides of the shoe sole and both sides of the bottom of the shoe sole will be exposed on both sides of the middle mold 3, facilitating the worker to drag the shoe sole from both sides to demold it. Moreover, as the side mold 4 is pressed down, the semi-circular guard plate 14 fixed to the side end of the side mold 4 rotates together. At this time, the bottom end of the semi-circular guard plate 14 no longer abuts against the cross plate 20, and the arc-shaped ejector rod 18 at the bottom of the side mold 4 pushes the cross plate 20 upward through the ball 19 at its end. In this way, the cross plate 20 drives the ejector plate 8 to move upward, thereby effectively ejecting the shoe sole in the shoe sole forming groove of the middle mold 3, so that the shoe sole can be easily demolded from the shoe sole forming groove of the middle mold 3 without the need for the worker to drag it. And through the setting of the semi-circular guard plate 14, during the hot pressing process, the bottom end of the semi-circular guard plate 14 abuts against the cross plate 20, preventing the ejector plate 8 from disengaging from the reserved groove in the shoe sole forming groove of the middle mold 3 during the hot pressing process, ensuring that the ejector plate 8 is tightly buckled in the reserved groove, effectively preventing the raw materials from flowing out through the reserved groove. Moreover, during the demolding process, through the setting of the semi-circular guard plate 14, during the separation process of the shoe sole forming groove on the side mold 4 and the shoe sole forming groove of the middle mold 3, the outer arc surface of the semi-circular guard plate 14 can effectively protect the shoe sole, preventing the shoe sole from directly contacting and bumping against the edges and corners on the side mold 4 and the middle mold 3 during the separation process, thereby effectively avoiding damage to the shoe sole.
