Description

Technical Field

[0001] This utility model relates to the technical field of rubber roller manufacturing equipment, specifically to an injection molding device for rubber rollers. Background Technology

[0002] In the textile industry, rubber rollers are an indispensable key component in various textile machinery, playing a vital role in the dyeing, printing, and finishing processes of textiles. Traditional rubber roller forming methods, such as mechanical or manual pasting, require a lot of manpower and time in the forming process. They are not only cumbersome to operate, but also have low production efficiency and cannot meet the needs of large-scale production. In order to improve this situation, it is particularly important to develop a rubber roller injection molding device.

[0003] According to CN218948370U, a rubber roller injection molding device includes a frame. An upper injection mold and a lower injection mold are mounted on the top of the frame. An injection pipe is connected through the top of the upper injection mold, and a hydraulic rod is connected for transmission. The hydraulic rod, support frame, guide rod, and buffer components form a longitudinal lifting structure. The screw drive component, transition connecting plate, guide plate, and slide rail form a transverse reciprocating movement structure. The longitudinal lifting structure, transverse reciprocating movement structure, and the upper and lower injection molds are integrated into a single assembly. After installation, a multi-functional injection molding device for rubber rollers will be formed. In the specific operation process, the hydraulic rod drives the upper injection mold, and the screw drive component drives the lower injection mold through the transition connecting sleeve plate, so that the upper and lower injection molds automatically reset and close for injection molding, and automatically separate and remove the mold after injection molding. As can be seen from the above, although this device can be used well, it is usually not convenient to air cool the mold components, which makes the mold easy to be in a high temperature state, and thus easily causes deformation and damage, affecting the injection molding effect of the rubber roller. Further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an injection molding device for rubber rollers, so as to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to air-cool the mold components, which makes the mold easy to be in a high temperature state, and thus easily causes deformation and damage, thereby affecting the injection molding effect of rubber rollers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection molding device for rubber rollers, comprising a frame, a worktable fixed to the top of the frame, a component holder provided on one side of the top of the worktable, a lower mold mounted on the top of the worktable on one side of the component holder, an upper mold above the lower mold, the bottom of the upper mold contacting the top of the lower mold, a support seat provided on the outer wall behind the frame, a component holder provided at the top of the support seat, guide rails provided at both ends of the surface of the component holder, and a component slidably mounted on one side of each guide rail surface.

[0008] Preferably, the surface of the upper mold at the upper mold cavity position is provided with injection holes, one end of which extends into the interior of the upper mold cavity. The injection holes are provided to inject hot melt material into the upper mold cavity and the lower mold cavity.

[0009] Preferably, a lifting cylinder is installed at the top of the component holder, the bottom end of the lifting cylinder passes through the component holder and is connected to the top of the upper mold, the input end of the lifting cylinder is connected to the top of the upper mold, and guide cylinders are provided on the top of the component holders on both sides of the lifting cylinder.

[0010] Preferably, two positioning corner seats are provided on both outer walls at the lower end of the frame, and a positioning hole is provided at the center of the bottom of each positioning corner seat. The positioning hole and the positioning corner seat are used to bolt and position the injection molding device.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the injection molding device for the rubber roller not only reduces the phenomenon of deformation damage to the upper and lower molds caused by high temperature, thus ensuring the injection molding effect of the rubber roller, but also improves the convenience of using the injection molding device and ensures the stability of the injection molding device during use.

The blower can be moved and aligned to one side of the upper mold and the lower mold. When the motor is started to drive the built-in fan blades of the blower to rotate, the blower can blow air energy to the upper mold and the lower mold to cool the upper mold and the lower mold, thereby reducing the deformation and damage of the upper mold and the lower mold due to high temperature, and ensuring the injection molding effect of the rubber roller.

[0013] (2) The upper mold is driven to move downward by the lifting cylinder, so that the upper mold drives the guide column to slide downward inside the guide cylinder, so that the upper mold moves down smoothly and contacts the lower mold. Then, the hot melt material used for the rubber roller is injected into the upper mold cavity and the lower mold cavity through the injection hole, so that the rubber roller can be injection molded, thereby improving the convenience of using the injection molding device.

[0014] (3) By setting up several positioning angle seats and positioning holes, the frame can be bolted and locked to the ground by means of bolts passing through the positioning holes and screwing into the ground, thereby ensuring the stability of the injection molding device during use.

[0031] A support seat 11 is provided on the outer wall behind the frame 1. A component placement seat 12 is provided at the top of the support seat 11. Guide rails 13 are provided at both ends of the surface of the component placement seat 12. A rail block 18 is slidably installed on one side of the surface of the guide rail 13.

When the starter motor 16 drives the fan blades built into the blower 15 to rotate, the blower 15 can blow air onto the upper mold 9 and the lower mold 10 to cool them down. This effectively reduces the deformation and damage to the upper mold 9 and the lower mold 10 caused by high temperature, thus completing the use of the injection molding device.
