Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to a rain shoe mold structure. Background Art

[0002] As labor protection and rain and snow weather utensils, rain shoes can well protect people's travel. During the processing of rain shoes, when the sole is injection molded, hot-melt rubber is injected into the mold. After the rubber solidifies, the mold is opened, and the molded rain shoes are taken off from the core. During the operation, since there is no air inside the rain shoes and they are tightly attached to the core, the external atmospheric pressure presses the rain shoes and the core tightly together, making it difficult to take off the rain shoes. In addition, when injecting hot-melt rubber into the mold, the hot-melt rubber will be unevenly distributed during the flow from the feed port, resulting in uneven problems such as thickness and quality in the later stage of rain shoe molding.

[0003] Therefore, we provide a rain shoe mold structure to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rain shoe mold structure. By installing an air ejector tube in the air channel opened in the core, when the solidified rain shoes need to be taken off, the air compressor ventilates into the air channel, so that the air ejector tube jacks up and discharges compressed air from the air outlet holes of the air ejector tube, thereby separating the rain shoes from the core. By dividing the top mold with a feed port into a mold closing panel and a feed panel, after the hot-melt rubber enters from the feed port, it is further divided by the feed capillary of the mold closing panel, so that the hot-melt rubber is evenly filled into the mold, solving the problems of laborious removal of rain shoes from the mold and uneven filling of hot-melt rubber.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a rain shoe mold structure, including a core and a cavity. The cavity includes a first mold closing part, a second mold closing part and a top mold. The core is in the shape of a cavity inside the rain shoe. The core is provided with an air channel along the shoe upper inlet to the sole. The two ends of the air channel are respectively opened at the shoe upper inlet and the shoe bottom surface of the core. An air ejector tube is installed in the air channel. A sealing cover matching the air outlet is fixedly installed at the air outlet of the air ejector tube in the air channel. The side wall of the air ejector tube near one end of the sealing cover is provided with air outlet holes. A limiting edge is fixedly arranged along the circumference at the pipe orifice of the air ejector tube far from the sealing cover end. A retaining ring is fixedly arranged inside the pipe wall of the air channel near the air inlet end of the air channel. An air ejector spring is sleeved between the limiting edge on the air ejector tube and the retaining ring inside the air channel. The air inlet of the air channel is connected with the air output end of the air compressor through a pipeline.

[0007] The present utility model is further configured such that the top mold includes a mold - closing panel and a feeding panel. The mold - closing panel is provided with a cavity concave surface in the shape of a shoe sole on one side within the mold cavity, and feeding capillary holes penetrating the mold - closing panel are arrayed along the edge of the cavity concave surface.

[0008] The present utility model is further configured such that one side of the feeding panel is provided with a feeding concave surface in the shape of a shoe sole, a feeding port is provided on the panel of the feeding panel, and the feeding panel is fixedly installed on the side of the mold - closing panel where the feeding concave surface is opened.

[0009] The present utility model is further configured such that a cooling water pipeline is provided within the core, and the input end of the cooling water pipeline is connected to a cooling water circulation device.

[0010] The present utility model is further configured such that one side of the first mold - closing part and the second mold - closing part are both hinged on a rotating shaft.

[0011] The present utility model is further configured such that one end of the rotating shaft is hinged to the mold - closing panel.

[0012] The present utility model has the following beneficial effects:

[0013] In the present utility model, compressed air is introduced into the air - jacking pipe within the internal air passage of the core through an air compressor to jack up the air - jacking pipe, so that the sealing cover at one end of the air - jacking pipe jacks up the rain boots from the core, and the compressed gas is discharged from the air outlet holes and fills the gap between the rain boots and the core, separating the rain boots from the core, thus facilitating the removal of the rain boots from the mold core.

[0014] In the present utility model, the top mold provided with the feeding port is divided into a mold - closing panel and a feeding panel. After the hot - melt rubber enters from the feeding port, it is further divided through the feeding capillary tubes of the mold - closing panel, enabling the hot - melt rubber to uniformly fill the mold.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0025] Please refer to Figures 1 to 2 , the present invention is a rain shoe mold structure, including a core 1 and a cavity 2. The cavity 2 includes a first mold closing 201, a second mold closing 202 and a top mold 203. Compressed air is introduced into the air ejector pipe 102 in the air channel 101 inside the core 1 through the air compressor 104 to lift the air ejector pipe 102, so that the sealing cap 102a at one end of the air ejector pipe 102 lifts the rain shoe from the core 1, and the compressed gas is discharged from the air outlet hole and fills the gap between the rain shoe and the core 1, so that the rain shoe is separated from the core 1, making it easy to remove the rain shoe from the mold core 1.

[0026] Specifically, the core 1 is in the shape of the cavity inside the rain boots. The core 1 is provided with an air duct 101 that runs from the entrance of the shoe upper towards the sole. The two ends of the air duct 101 are respectively opened at the entrance of the shoe upper and the bottom surface of the core 1. An air jacking tube 102 is installed inside the air duct 101. At the air outlet of the air duct 101, the air jacking tube 102 is fixedly installed with a sealing cap 102a that matches the air outlet. On the side wall of the air jacking tube 102 near one end of the sealing cap 102a, air outlet holes 102b are provided. Along the circumference of the pipe orifice at the end of the air jacking tube 102 far from the sealing cap 102a, a limiting edge 102c is fixedly provided. Inside the pipe wall of the air duct 101 near the air inlet end of the air duct 101, a retaining ring 101a is fixedly provided. Between the limiting edge 102c on the air jacking tube 102 and the retaining ring 101a inside the air duct 101, an air jacking spring 102d is sleeved on the air jacking tube 102. The air inlet of the air duct 101 is connected to the air output end of the air compressor 103.

[0027] The operation process of this embodiment is as follows:

[0028] Close the first mold clamping plate 201, the second mold clamping plate 202 and the top mold 203, and inject the hot melt rubber into the mold. After the injection is completed, the air compressor 103 injects compressed air into the air jacking tube 102. The compressed air is discharged from the air outlet holes 102b on the air jacking tube 102 and fills the air duct 101. When the air duct 101 is filled with compressed air, the compressed air jacks up the sealing cap 102a of the air jacking tube 102 and injects the compressed air into the gap between the rain boots and the core 1, separating the core 1 from the inner wall of the rain boots that are adhered to the core 1 after shaping, so that the rain boots can be more easily removed from the core 1. Embodiment 2

[0029] Please refer to Figures 1 to 5 , on the basis of Embodiment 1, the top mold 203 includes a mold clamping panel 203a and a feeding panel 203b. By dividing the top mold 203 with a feeding port into a mold clamping panel 203a and a feeding panel 203b, after the hot melt rubber enters from the feeding port, it is further divided through the feeding capillary 203a-2 of the mold clamping panel 203a, so that the hot melt rubber is evenly filled into the mold.

[0030] Specifically, on one side of the mold cavity of the mold clamping panel 203a, a cavity concave surface 203a-1 in the shape of the sole is provided. Along the edge, a series of feeding capillary holes 203a-2 that penetrate through the mold clamping panel 203a are provided, so that the hot melt rubber can be fully and evenly filled into the mold.

[0031] Further, a sole-shaped feeding concave surface 203b-1 is formed on one side of the feeding panel 203b, and a feeding port 203b-2 is formed on the panel of the feeding panel 203b. The feeding panel 203b is fixedly installed on the side of the mold clamping panel 203a where the feeding concave surface 203b-1 is formed. The hot melt rubber is injected from the feeding port 203b-2, reaches the feeding concave surface 203b-1, and evenly distributes the hot melt rubber to the feeding capillary holes 203a-2 through the feeding concave surface 203b-1.

[0032] Further, a cooling water pipe 104 is provided in the core 1, and the input end of the cooling water pipe 104 is connected to a cooling water circulation device 105. The cooling water circulation device 105 pumps the cooling water into the cooling water pipe 104 to quickly cool and harden the shaped hot melt rubber.

[0033] Further, one side of the first mold clamping part 201 and the second mold clamping part 202 is hinged to a rotating shaft 204, which is convenient for the mold clamping and docking of the first mold clamping part 201 and the second mold clamping part 202 when injecting the hot melt rubber.

[0034] Further, one end of the rotating shaft 204 is hinged to the mold clamping panel 203a, so as to facilitate opening and closing the mold clamping panel 203a and ensure the integrated structure of the mold.

[0035] The operation process of this embodiment is as follows: After the hot melt rubber is injected from the feeding port 203b-2, it enters the feeding capillary holes 203a-2 on the mold clamping panel 203a, and finally is injected into the mold through the shunt of the feeding capillary holes 203a-2, so that the hot melt rubber is more evenly filled into the mold to prevent the quality and thickness of the rain shoes from being inconsistent due to uneven filling. After the injection of the hot melt rubber is completed, the cooling water circulation device 105 injects cooling water into the cooling water pipe 104 in the core 1 to quickly cool and harden the shaped hot melt rubber, thereby preventing the high-temperature shaped product from scalding the operator, reducing the cooling time after shaping, and improving the production efficiency.
