Description
Technical Field
The invention relates to a safety protection mechanism, in particular to an adjustable switch for limiting the travel of a sliding part in injection molding equipment and preventing high potential energy from impacting.
Background
In addition to the mold for opening and closing operations, some sliding parts with larger weight and inertia are controlled to operate in the injection manufacturing process in the current injection molding equipment. Typically, such sliding components require stroke control, but due to inertia effects there is often a risk of an out-of-stroke impact even at the end of the electrical power supply. For this purpose, designers have provided anti-collision mechanisms for the sliding members.
However, since the injection molding apparatus processes a wide variety of products, sliding potential energy of the sliding member is different under different working conditions. For this reason, a single stiffness spring-based impact mechanism is not universally applicable. If the anti-collision mechanism with different buffer capacities is replaced every time, the processing efficiency tends to be low, and the production cost is increased intangibly.
Disclosure of Invention
In view of the defects of the prior art, the invention aims to provide an adjustable switch for injection molding of a mold, which can realize flexible regulation and control of the buffer capacity of an anti-collision mechanism through simple operation.
The aim of the invention is achieved by the following technical scheme: an adjustable switch for injection molding of a mold is arranged at the stroke end of a sliding part in injection molding equipment, and is characterized in that: the adjustable switch is formed by assembling a basic positioning block, a spring, a bolt, a magnet block and a limit anti-collision switch, wherein the magnet block is provided with a contact cap facing the sliding part, the spring is arranged between the basic positioning block and the magnet block, the bolt sequentially penetrates through the basic positioning block and the spring and is in threaded connection with the magnet block and the tensioning spring, and the limit anti-collision switch is fixedly connected to the side of the basic positioning block, senses magnetic field change and feeds signals back to a main control unit of the injection molding equipment; and the tensioning force of the spring is adjustable in depth through bolt screwing.
Further, the adjustable switch is provided with two sets of bolts and springs, and the two sets of bolts and springs are symmetrically distributed relative to the contact cap.
Further, the adjustable switch is provided with three sets of bolts and springs, and the three sets of bolts and springs are uniformly distributed in the circumferential direction relative to the contact cap.
The adjustable switch has the beneficial effects that: reasonable switch reaction action can be obtained through simple test die and adjusting bolt screw connection depth, so that the stroke control of the switch on sliding parts in injection equipment is greatly improved, die rejection caused by abnormal die closing is prevented, and the product manufacturing period is delayed. And simultaneously, the operation noise and depreciation loss of the equipment are reduced.
Drawings
Fig. 1 is a schematic diagram of an adjustable switch according to the present invention.
Description of the embodiments
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings, so that the technical scheme of the present invention can be understood and mastered more easily.
The adjustable switch for injection molding of the mold is arranged at the stroke end of a sliding part in injection molding equipment. The structural characteristics of the adjustable switch can be seen from fig. 1, and the adjustable switch is generally formed by assembling a basic positioning block 1, a spring 2, a bolt 3, a magnet block 4 and a limit anti-collision switch 5, wherein the magnet block 4 is provided with a contact cap 6 facing a sliding part (not shown), the spring 2 is arranged between the basic positioning block 1 and the magnet block 4, and the bolt 3 sequentially penetrates through the basic positioning block 1 and the spring 2 and is in threaded connection with the magnet block 4, so that the spring maintains a certain external tension, namely the spring is tensioned. On the other hand, the limit anti-collision switch 5 is fixedly connected to the side of the basic positioning block 1, and is mainly used for sensing magnetic field change caused by displacement of the magnet block 4 and feeding back signals to a main control unit of the injection molding equipment, so that the action energy supply of the sliding part is further emergently cut off. As creation bright spots, an adjustable switch capable of adapting to various sliding potential energy is realized by: the tension of the spring can be adjusted by the depth of the bolt engagement.
In the illustrated embodiment, the adjustable switch is provided with two sets of bolts 3 and springs 2, and is symmetrically arranged with respect to the contact cap 6.
In addition to the above embodiments, the adjustable switch may be configured with three or more bolts and springs, and disposed in a circumferentially uniform distribution with respect to the contact cap. The adjusting precision of the switch is further improved.
From the foregoing, it can be clearly understood that: by applying the adjustable switch, reasonable switch reaction action can be obtained through simple test die and adjusting bolt screwing depth, so that the stroke control of the switch on sliding parts in injection equipment is greatly improved, die rejection caused by abnormal die assembly is prevented, and the product manufacturing period is delayed. And simultaneously, the operation noise and depreciation loss of the equipment are reduced.
The invention has various embodiments, and all technical schemes formed by equivalent transformation or equivalent transformation fall within the protection scope of the invention.
