Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an in-mold pedal device of an injection molding machine. Background Art

[0002] The injection molding machine is a widely used equipment in the plastic processing industry, mainly used to manufacture various plastic products. It melts plastic granules or powders by heating them, injects them into the mold, and applies high pressure to fill the mold cavity to form the desired shape and size. The working process of the injection molding machine includes the following key steps: First, the plastic granules or powders are loaded into the hopper of the injection molding machine. Then, the plastic in the barrel is heated to the melting temperature by the heating system, usually between 150 and 300 degrees Celsius, depending on the type of plastic. Once the plastic is completely melted, the injection molding machine will inject it into the mold. The injection system of the injection molding machine uses high pressure to push the molten plastic into the mold cavity to ensure that every detail in the mold is fully filled. After the injection is completed, the mold is opened and the molded plastic product is taken out after the plastic cools and solidifies. These products can be parts of various shapes and sizes, used in many industries such as the automotive industry, electronic equipment, and household goods. The advantages of the injection molding machine include short production cycle, high molding accuracy, and stable product quality, so it has been widely used in industrial production. With the advancement of technology, modern injection molding machines are not only capable of automated operation, but also have higher intelligence and energy-saving and environmental protection features, bringing greater efficiency and sustainability to the production of plastic products.

The displacement of the pedal device may cause the demolding process to be unsmooth or interrupted, thereby increasing the production downtime; therefore, it does not meet the existing needs. In this regard, we propose an in-mold pedal device for an injection molding machine. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1: This embodiment is intended to solve the problem that when the pedal device is demoulding, if the force is unevenly applied or the direction is incorrect during the demoulding process, the pedal device may be displaced. The displacement of the pedal device may cause the demoulding process to be unsmooth or interrupted, thereby increasing the production downtime. Please refer to Figure 1-6An in-mold pedal device of an injection molding machine includes a driving plate 110 and a movable pedal 120. The driving plate 110 is correspondingly arranged on the side of the movable pedal 120. A support frame 130 is connected to the bottom of the movable pedal 120. A telescopic component 140 is installed on the side of the support frame 130. The telescopic component 140 is used in conjunction with the movable pedal 120. A cylinder is arranged on the side of the driving plate 110, and the cylinder drives the driving plate to rise.

[0024] A sliding groove 121 is provided on the surface of the moving pedal 120, and the sliding groove 121 is set as a piston groove. A sliding rod 111 is connected to the surface of the driving plate 110, and the sliding rod 111 is set as a rubber rod. The sliding rod 111 is slidably matched with the sliding groove 121. The telescopic assembly 140 includes a fixed rod 141 and a telescopic column 142. The fixed rod 141 is set as an L-shaped rod. The fixed rod 141 is connected to the side of the support frame 130, and the telescopic column 142 is connected to the side of the fixed rod 141.

[0025] Setting a rubber rod as the sliding rod 111 can enable it to run smoothly in the sliding groove 121, reducing the friction caused by direct contact between metal and metal, while also improving wear resistance and extending the service life of the sliding rod 111. The elasticity of the rubber rod can absorb impact and vibration when sliding on the surface of the moving pedal 120, providing smooth and stable movement, reducing noise and vibration during operation, and improving operating comfort.

[0026] A return spring 145 is sleeved on the outer side of the telescopic column 142. The telescopic column 142 includes a fixed cylinder 143 and a sliding cylinder 144. The fixed cylinder 143 is connected to the side of the fixed rod 141. The sliding cylinder 144 is connected to the bottom of the moving pedal 120. The sliding cylinder 144 is sleeved on the outer side of the fixed cylinder 143. The inner wall of the sliding cylinder 144 is connected to a stabilizing rod 150. The bottom of the stabilizing rod 150 is connected to a sliding disk 151. The sliding disk 151 is set as a rubber disk. The sliding disk 151 is slidably matched with the inside of the fixed cylinder 143.

[0027] The rubber disc as the sliding disc 151 and the contact with the inner wall of the fixed cylinder 143 can effectively reduce the friction and noise generated during movement. This setting can maintain the stability and quietness of the movement process, improve the operating comfort of the equipment, and the stabilizing rod 150 slides in the fixed cylinder 143 through the sliding disc 151, ensuring the stability and accuracy of the telescopic column 142 during the demoulding process, which is particularly critical for the opening and closing process of the mold, and can ensure the consistency of the size and shape of the product.

[0028] In this embodiment: through the setting of the telescopic component 140, when demoulding is required, the driving plate 110 rises, squeezing the telescopic column 142 and the return spring 145, and the sliding cylinder 144 drives the stabilizing rod 150 and the moving plate to slide inside the fixed cylinder 143, so that the sliding rod 111 slides inside the sliding groove 121. The use of the telescopic component 140 makes the demoulding process more efficient and reliable. Precise control and stable movement ensure the continuous operation of the production line, reduce the production line downtime caused by poor demoulding, improve production efficiency and capacity utilization, and solve the problem that when the pedal device is demoulding, if the force is unevenly applied or the direction is incorrect during the demoulding process, the pedal device may be displaced. The displacement of the pedal device may cause the demoulding process to be unsmooth or interrupted, thereby increasing the production downtime.

[0029] Embodiment 2: This embodiment is intended to promote the solution to the problem of the sliding rod 111 sliding stuck. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 The inner wall of the sliding groove 121 is rollingly connected with a ball 152, and the ball 152 is slidingly matched with the sliding rod 111. The use of the ball 152 makes the sliding rod 111 more stable and controllable during the demoulding process, reducing the possibility of accidents caused by improper operation or uneven force application. This is beneficial to the safety and work efficiency of the operator.

[0030] In the present embodiment, the ball 152 is arranged to cooperate with the sliding groove 121 and the sliding rod 111. When the sliding rod 111 slides with the sliding groove 121, the ball 152 and the sliding rod 111 roll. The rolling contact between the ball 152 and the sliding groove 121 and the sliding rod 111 greatly reduces the friction resistance. Compared with the traditional direct sliding method, it can reduce energy loss and improve movement efficiency.
